Description

Fixing structure for linear member and injection molding machine

This disclosure relates to a fixing structure for a linear member and an injection molding machine.

Japanese Patent Application Laid-Open Publication No. 2002-232161 discloses a structure for fixing lead wires to a substrate. Two through holes are formed in the substrate. A worker passes one end of a cable tie from the surface of the substrate through one of the through holes. Next, the worker inserts their hand into the back of the substrate and passes the end of the cable tie that passed through the through hole through the other through hole. This allows the worker to pull one end of the cable tie out to the surface of the substrate. A lead wire is positioned between the two through holes on the surface of the substrate. The worker connects both ends of the cable tie to fix the lead wire to the substrate.

There is a strong demand for a fixing structure that can simply and easily fix linear members used in injection molding machines to the injection molding machine.

A first aspect of the present disclosure is a fixing structure for fixing a linear member used in an injection molding machine to the injection molding machine, the fixing structure for a linear member comprising a plate member having a through hole formed therein, and a tongue portion that protrudes from the inner wall of the through hole of the plate member and is positioned within the through hole.

A second aspect of the present disclosure is an injection molding machine equipped with the linear member fixing structure of the first aspect.

In industrial machinery such as injection molding machines, linear members used in the industrial machinery may need to be fixed to the industrial machinery. In this case, for example, two through holes are formed in the plate member that makes up the industrial machinery. A worker passes one end of a cable tie from the surface of the plate member through one of the through holes. Next, the worker inserts their hand into the back of the plate member and passes the end of the cable tie that passed through the through hole through the other through hole. This allows the worker to pull one end of the cable tie to the surface of the plate member. Next, the worker places the linear member between the two through holes on the surface of the plate member. After that, the worker secures the linear member to the plate member by connecting both ends of the cable tie.

However, when two through holes are formed in a relatively narrow location, the worker cannot reach behind the plate member. The objective of the technology disclosed herein is to provide a fixing structure and injection molding machine that can simply and easily fix a linear member to a plate member.

[Present embodiment]
Figure 1 is a side view of an injection molding machine 10 of this embodiment. The injection molding machine 10 includes a machine base 12, a mold clamping device 14, an injection device 16, and a plurality of control devices 18. The front-to-rear direction of the injection molding machine 10 is the left-to-right direction in Figures 1 and 2. The height direction of the injection molding machine 10 is the up-to-down direction in Figure 1. The width direction of the injection molding machine 10 is a direction perpendicular to the front-to-rear direction and the height direction.

The machine base 12 is placed on the floor (not shown) of the installation location of the injection molding machine 10. The machine base 12 may be supported on the floor via multiple support mechanisms (not shown). The machine base 12 has an upper frame 20, a lower frame 22, multiple support columns 24, a first floor plate 26, and a second floor plate 28.

The lower frame 22 is installed on the floor. The lower frame 22 is made of, for example, steel. As shown in Figures 1 and 2, the lower frame 22 has a first member 30, a second member 32, and multiple third members 34. Note that the upper frame 20 and multiple support columns 24 are not shown in Figure 2.

The first member 30, the second member 32, and the multiple third members 34 are pipe-shaped members. The first member 30 and the second member 32 extend in the front-to-rear direction of the injection molding machine 10. The first member 30 and the second member 32 are arranged on the floor surface at intervals in the width direction of the injection molding machine 10. The multiple third members 34 are arranged at intervals in the front-to-rear direction between the first member 30 and the second member 32. Each of the multiple third members 34 extends in the width direction. The multiple third members 34 connect the first member 30 and the second member 32.

As shown in FIG. 1, the multiple support columns 24 extend upward from the first member 30 or the second member 32. The multiple support columns 24 are made of, for example, steel.

The upper frame 20 is joined to the upper end surfaces of multiple support columns 24. The upper frame 20 is positioned above the lower frame 22. The upper frame 20 is supported by the lower frame 22 via multiple support columns 24. The upper frame 20 is made of, for example, steel.

As shown in Figures 1 and 2, a first floor plate 26 and a second floor plate 28 are arranged on the lower frame 22. The first floor plate 26 and the second floor plate 28 are supported by the first floor plate 26 and the second floor plate 28, for example, below the injection device 16, so as to straddle the first member 30 and the second member 32. The first floor plate 26 and the second floor plate 28 are supported by the first member 30 and the second member 32 with a gap therebetween above the floor surface. The first floor plate 26 and the second floor plate 28 are arranged side by side in the front-to-rear direction between the first member 30 and the second member 32. The first floor plate 26 and the second floor plate 28 are made of a material such as steel, for example.

The mold clamping unit 14 is arranged on the upper frame 20. The mold clamping unit 14 has a fixed platen 36, a rear platen 38, a movable platen 40, a mold 42, multiple tie bars 44, and a toggle mechanism 46. The mold 42 is composed of a fixed mold 48 and a movable mold 50.

The injection unit 16 is arranged on the upper frame 20 so as to face the mold clamping unit 14 in the front-to-rear direction. The injection unit 16 has an injection section 52, a cylinder section 54, and a nozzle 56. The mold clamping unit 14 and the injection unit 16 are arranged on the upper frame 20 so that the fixed platen 36 and the nozzle 56 face each other in the front-to-rear direction. Note that the configurations of the mold clamping unit 14 and the injection unit 16 are well known, so a detailed description thereof will be omitted.

A control panel 58 is arranged on the first floor plate 26. The control panel 58 is, for example, a high-voltage panel for controlling the mold clamping unit 14 and the injection unit 16. The control panel 58 has a duct 60 and multiple control devices 18. The duct 60 is arranged on the upper surface of the first floor plate 26. The duct 60 extends in the front-to-rear direction on the upper surface of the first floor plate 26. The duct 60 is a hollow housing. The duct 60 is composed of multiple plate-shaped frames 62 (fixed frames). The duct 60 is made of, for example, steel.

The multiple control devices 18 are fixed to the side of the duct 60. More specifically, the multiple control devices 18 are fixed to one frame 64 of the multiple frames 62 that make up the duct 60. The single frame 64 stands on the first floor plate 26 and extends in the front-to-rear direction. The multiple control devices 18 are fixed to the surface of the single frame 64 at intervals in the front-to-rear direction.

Each of the multiple control devices 18 is a high-voltage device for controlling the mold clamping device 14 and the injection device 16. In more detail, each of the multiple control devices 18 controls the mold clamping device 14 and the injection device 16 based on command signals from a numerical control device (not shown) located outside the injection molding machine 10.

The injection molding machine 10 further includes a plurality of linear members 70. The linear members 70 are flexible wiring. Examples of wiring include power cables for supplying electric power, signal cables for transmitting electrical signals, and piping for supplying air.

The injection molding machine 10 further includes a fixing structure 80 (fixing structure for the linear member) for fixing the linear member 70 to the injection molding machine 10. The fixing structure 80 will be described with reference to Figure 3A.

The fixing structure 80 has a plate member 82 and a tongue portion 84. The plate member 82 is part of the injection molding machine 10. A through hole 86 is formed in the plate member 82. The tongue portion 84 protrudes into the through hole 86 from an inner wall 88 of the plate member 82 that forms the through hole 86. The tongue portion 84 is positioned within the through hole 86.

The tongue portion 84 is rectangular in shape. Of the four sides of the tongue portion 84, one side 90 is connected to the inner wall 88 that forms the through hole 86. In Figure 3A, the side 90 is shown with a dashed line. The side 90 forms the base end of the tongue portion 84. The other three sides other than the side 90 are arranged within the through hole 86, separated from the inner wall 88 by a gap 91. Of the three sides, the side 92 facing the side 90 forms the tip of the tongue portion 84. Two sides 94 between the base end and tip of the tongue portion 84 form the side edges of the tongue portion 84. The two sides 94 face each other. The two sides 94 are connected to the side 90.

The tongue portion 84 may have parallel portions 96 that are parallel to each other. The two parallel portions 96 are formed by two sides 94 that form the side edges of the tongue portion 84. For each of the two sides 94, the entire side 94 forms the parallel portion 96. Therefore, in FIG. 3A, the two parallel portions 96 are connected to one side 90. Note that each of the two parallel portions 96 may be formed by a portion of the side 94.

The length L of the tongue portion 84 in the protruding direction (the distance between the base end and tip end of the tongue portion 84) is shorter than the width H of the tongue portion 84 in the direction perpendicular to the protruding direction (the distance between the two side edges of the tongue portion 84) (L<H). The width H of the tongue portion 84 may be approximately the same as the width or diameter of the linear member 70. Alternatively, the width H of the tongue portion 84 may be slightly larger than the width or diameter of the linear member 70. The length L of the tongue portion 84 in the protruding direction may be slightly larger than the width of the fixing device 100, which will be described later.

The linear member 70 is positioned on the tongue portion 84 in the direction in which the tongue portion 84 protrudes. The tongue portion 84 and the linear member 70 are fixed together with a linear fastener 100 such as a cable tie. Figure 3A shows an example in which one linear member 70 is fixed to the tongue portion 84 with the fastener 100.

Specifically, the linear fastener 100 is bent into a U-shape, and the bent portion is inserted into the through-hole 86 from the surface of the plate member 82 (the surface of the plate member 82 on which the linear member 70 is arranged). Next, the fastener 100 is slid in the direction opposite the protruding direction of the tongue portion 84, so that the bent portion is arranged on the back side of the tongue portion 84 (the opposite side of the tongue portion 84 from the linear member 70). At this time, both ends of the fastener 100 pass through the through-hole 86 and protrude to the front side of the tongue portion 84 (the side of the tongue portion 84 on which the linear member 70 is arranged). Thereafter, the fastener 100 is tightened and both ends of the fastener 100 are connected, thereby fixing the linear member 70 to the tongue portion 84. As a result, the linear member 70 is fixed to the plate member 82.

In addition, two or more linear members 70 may be fixed to the tongue portion 84 by the fixing device 100.

The fixing structure 80 configured as described above is provided, for example, in the following locations in the injection molding machine 10 shown in Figures 1 and 2.

The fixing structure 80 may be provided on the injection device 16. Specifically, a bracket 110, which is a plate member 82, is fixed to the surface of the injection section 52 of the injection device 16. The bracket 110 is a plate-shaped member. Both ends of the bracket 110 are fixed to the surface of the injection section 52. The middle portion of the bracket 110 is positioned at a distance from the surface of the injection section 52. A through hole 86 (see Figure 3A) and a tongue portion 84 are formed in the middle portion of the bracket 110. The linear member 70 is fixed to the middle portion of the bracket 110. The linear member 70 is, for example, wiring connected to an electrical component arranged in the injection device 16.

The fixing structure 80 may be provided on the mold clamping unit 14. The fixing structure 80 is provided on at least one of the fixed platen 36, the rear platen 38, and the movable platen 40. Figure 1 illustrates the case where the fixing structure 80 is provided on the fixed platen 36. When the fixing structure 80 is provided on the fixed platen 36, a bracket 112, which is a plate member 82, is fixed to the surface of the fixed platen 36. The bracket 112 is a plate-shaped member. Both ends of the bracket 112 are fixed to the surface of the fixed platen 36. The middle portion of the bracket 112 is positioned at a distance from the surface of the fixed platen 36. A through hole 86 and a tongue portion 84 are formed in the middle portion of the bracket 112. The linear member 70 is fixed to the middle portion of the bracket 112. The linear member 70 is, for example, wiring connected to electrical components arranged in the mold clamping unit 14. When the fixing structure 80 is provided on the rear platen 38, the bracket 112 is fixed to the surface of the rear platen 38. When the fixing structure 80 is provided on the movable platen 40, the bracket 112 is fixed to the surface of the movable platen 40.

The fixing structure 80 may be provided on the frame 64 of the duct 60 of the control panel 58. Specifically, the frame 64 is a plate member 82. A through hole 86 and a tongue portion 84 are formed in the frame 64 adjacent to the control device 18. The linear member 70 is, for example, a wire connected to the control device 18.

The fixing structure 80 may be provided on the machine base 12. Specifically, the fixing structure 80 is provided on the first floor plate 26 or the second floor plate 28. The plate member 82 is the first floor plate 26 or the second floor plate 28.

When the fixing structure 80 is provided on the first floor plate 26, a through hole 86 and a tongue portion 84 are formed in the first floor plate 26 adjacent to the control device 18. The linear member 70 is, for example, a wire connected to the control device 18.

When the fixing structure 80 is provided on the second floor plate 28, a through hole 86 and a tongue portion 84 are formed in the second floor plate 28. The linear member 70 is, for example, wiring connected to the control device 18.

Next, we will explain how to secure the linear member 70 to the injection molding machine 10.

First, the worker bends the linear fastener 100 into a U-shape and inserts the bent portion into the through-hole 86 from the surface of the plate member 82. Next, the worker slides the fastener 100 in the direction opposite to the protruding direction of the tongue portion 84. As a result, the bent portion of the fastener 100 is positioned on the back side of the tongue portion 84. Furthermore, both ends of the fastener 100 pass through the through-hole 86 and protrude from the front side of the tongue portion 84.

Next, the worker places the linear member 70 on the front side of the tongue portion 84 in the direction in which the tongue portion 84 protrudes. This positions the linear member 70 between both ends of the fixing device 100.

Next, the worker tightens the fastener 100 to connect both ends of the fastener 100. This secures the linear member 70 to the tongue portion 84. As a result, the linear member 70 is secured to the plate member 82.

The effects of this embodiment will be explained below.

As shown in FIG. 3A, the fixing structure 80 has a plate member 82 and a tongue portion 84. A through hole 86 is formed in the plate member 82. The tongue portion 84 protrudes from an inner wall 88 of the plate member 82 that forms the through hole 86 and is disposed within the through hole 86. As a result, the tongue portion 84 and the linear member 70 can be fixed together by inserting a linear fixing device 100 into the through hole 86 and tightening the fixing device 100. As a result, the linear member 70 can be fixed to the plate member 82 simply and easily.

One side 90 of the tongue portion 84 is connected to the inner wall 88, and the other sides are positioned within the through-hole 86, separated from the inner wall 88 by a gap 91. As a result, when the middle portion of the linear fastener 100 is inserted into the through-hole 86 and positioned on the back side of the tongue portion 84, both ends of the fastener 100 protrude from the through-hole 86 to the front side of the tongue portion 84. By tightening both ends of the fastener 100, the worker can easily secure the linear member 70 to the tongue portion 84.

Because the tongue portion 84 is rectangular, it can be easily formed.

The tongue portion 84 has parallel portions 96 that are parallel to each other. As a result, when the fastener 100 tightens the tongue portion 84 and the linear member 70, the fastener 100 comes into contact with the two parallel portions 96. As a result, the tongue portion 84 and the linear member 70 can be easily fastened.

The parallel portion 96 is connected to the inner wall 88. This allows the fixing device 100 to be positioned on the inner wall 88 and then tighten the tongue portion 84 and linear member 70.

The length L of the tongue portion 84 in the protruding direction is shorter than the length H in the width direction perpendicular to the protruding direction (L<H). This prevents the tongue portion 84 from breaking.

As shown in Figures 1 and 2, the plate member 82 is provided on at least one of the mold clamping unit 14, injection unit 16, machine base 12, and frame 64. This allows the linear member 70 to be fixed to the plate member 82 at any location on the injection molding machine 10.

In other words, by providing a plate member 82 on the side of the mold clamping unit 14 or injection unit 16, the linear member 70 can be easily fixed to the mold clamping unit 14 or injection unit 16. Also, by providing a plate member 82 on the machine base 12, such as the first floor plate 26 or the second floor plate 28, the linear member 70 can be fixed to the machine base 12 without removing the components that make up the machine base 12. Furthermore, by providing a plate member 82 on the frame 64, the linear member 70 can be easily fixed to the frame 64 even when various components are provided around the frame 64.

The linear member 70 is a flexible wiring. This allows the wiring and the tongue portion 84 to be fixed together using the fixing device 100.

[Modification]
Next, modified examples (1st to 16th modified examples) of the fixing structure 80 of this embodiment will be described with reference to Figures 3B to 12B. Note that, among the components of each modified example, the same components as those of this embodiment (see Figures 1 to 3A) are given the same reference numerals, and detailed description thereof will be omitted.

[First Modification]
As shown in Fig. 3B, in the first modified example, the tongue portion 84 has a trapezoidal shape. Therefore, the first modified example does not have the two parallel portions 96 (see Fig. 3A). In the first modified example, the effects of the present embodiment other than the two parallel portions 96 can be obtained.

[Second Modification]
As shown in Fig. 4A, in the second modified example, the tongue portion 84 has a triangular shape. Therefore, the second modified example does not have the two parallel portions 96 (see Fig. 3A). The second modified example also achieves the same effects as the present embodiment except for the two parallel portions 96.

[Third Modification]
As shown in Fig. 4B, in the third modified example, the tongue portion 84 has an arcuate shape. In the third modified example, one side 92 opposite one side 90 and two sides 94 are arcuate sides. Therefore, the third modified example does not have the two parallel portions 96 (see Fig. 3A). The third modified example also achieves the same effects as the present embodiment except for the two parallel portions 96.

[Fourth Modification]
5A, in the fourth modified example, the tongue portion 84 has a trapezoidal shape. However, in the fourth modified example, two parallel portions 96 are formed on the base end portion of the tongue portion 84. That is, the base end sides of the two sides 94 are formed into two parallel portions 96. The two parallel portions 96 are connected to one side 90. The fourth modified example also achieves the effects of this embodiment.

[Fifth Modification]
5B , in the fifth modified example, the tongue portion 84 has a triangular shape. However, in the fifth modified example, two parallel portions 96 are formed on the base end portion of the tongue portion 84. That is, the base end sides of the two sides 94 are formed into two parallel portions 96. The two parallel portions 96 are connected to one side 90. The fifth modified example also achieves the effects of this embodiment.

[Sixth Modification]
As shown in Fig. 5C, in the sixth modified example, the tongue portion 84 has an arcuate shape. Therefore, in the sixth modified example, the side 92 and the two sides 94 are arcuate sides, similar to the third modified example (see Fig. 4B). However, in the sixth modified example, two parallel portions 96 are formed at the base end portion of the tongue portion 84. That is, the base end sides of the two sides 94 are formed into two parallel portions 96. The two parallel portions 96 are connected to one side 90. The sixth modified example also achieves the effects of this embodiment.

[Seventh Modification]
The seventh modified example will be described with reference to FIGS. 6A and 6B.

In the seventh modified example, a pair of recesses 98 recessed toward each other are formed in the tongue portion 84. Specifically, a recess 98 is formed on each of the two opposing sides 94. The pair of recesses 98 are formed on the base end sides of the two sides 94. In other words, the pair of recesses 98 are formed adjacent to one side 90. Each of the pair of recesses 98 is rectangular in shape. Each of the pair of recesses 98 constitutes part of the parallel portion 96.

In the seventh modified example, the widthwise length H of the tongue portion 84 is the widthwise length of the portion of the tongue portion 84 where the recess 98 is not formed. Also, Figure 6A illustrates an example in which one linear member 70 is fixed to the tongue portion 84 by the fixing device 100. Figure 6B illustrates an example in which two linear members 70 are fixed to the tongue portion 84 by the fixing device 100.

In the seventh variant, when fixing the linear member 70 to the tongue portion 84, the worker moves the bent portion of the fixing device 100 to the recessed portion 98 on the back side of the tongue portion 84. As a result, both ends of the fixing device 100 protrude from the recessed portion 98 of the through-hole 86 to the front side of the tongue portion 84. When the worker tightens both ends of the fixing device 100, the fixing device 100 fits into a pair of recessed portions 98, fixing the tongue portion 84 and the linear member 70 together.

The effects of this embodiment can also be achieved with the seventh modified example. Furthermore, in the seventh modified example, a pair of recesses 98 recessed toward each other are formed in the tongue portion 84. As a result, when the tongue portion 84 and linear member 70 are fastened by the fastener 100, the fastener 100 fits into the recesses 98. As a result, the tongue portion 84 and linear member 70 can be fixed in place without the fastener 100 shifting in the protruding direction of the tongue portion 84.

[Eighth Modification]
As shown in Fig. 7A, in the eighth modified example, the tongue portion 84 has a trapezoidal shape. However, a pair of recesses 98 is formed on two sides 94 of the tongue portion 84. The pair of recesses 98 constitute two parallel portions 96. The eighth modified example also achieves the effects of the seventh modified example (see Figs. 6A and 6B).

[Ninth Modification]
As shown in Fig. 7B, in the ninth modified example, the tongue portion 84 has a triangular shape. However, a pair of recesses 98 is formed on two sides 94 of the tongue portion 84. The pair of recesses 98 constitute two parallel portions 96. The ninth modified example also achieves the effects of the seventh modified example (see Figs. 6A and 6B).

[Tenth Modification]
As shown in Fig. 8A, in the tenth modified example, the tongue portion 84 has an arcuate shape. However, a pair of recesses 98 are formed in the base end portion of the side edge of the tongue portion 84. The pair of recesses 98 constitute two parallel portions 96. The tenth modified example also achieves the effects of the seventh modified example (see Figs. 6A and 6B).

[Eleventh Modification]
As shown in Fig. 8B, in the eleventh modified example, the tongue portion 84 has a rectangular shape. However, a pair of recesses 98 is formed on two sides 94 of the tongue portion 84. Each of the pair of recesses 98 has a triangular shape. The eleventh modified example also achieves the effects of the seventh modified example (see Figs. 6A and 6B).

[Twelfth Modification]
As shown in FIG. 9 , in the twelfth modification, two tongue portions 84 protrude from an inner wall 88 of a plate member 82 that defines a through hole 86. The two tongue portions 84 are spaced apart in the width direction of the tongue portions 84. Each of the two tongue portions 84 has a rectangular shape, similar to the present embodiment (see FIG. 3A ). Therefore, a pair of recesses 98 (see FIGS. 6A and 6B ) is not formed in each of the two tongue portions 84. A linear member 70 is disposed on each of the two tongue portions 84. Each of the two tongue portions 84 is fixed integrally with the linear member 70 disposed on the tongue portion 84 by a fixing device 100. In the twelfth modification, the two linear members 70 can be easily fixed to the plate member 82. The effects of the present embodiment can also be achieved in the twelfth modification.

The twelfth variant may be combined with any of the variants described above. For example, the shape of the two tongue portions 84 may be triangular, trapezoidal, or arc-shaped. Furthermore, a pair of recesses 98 (see Figures 6A and 6B) may be formed in each of the two tongue portions 84.

[Thirteenth Modification]
As shown in FIGS. 10A and 10B , in the thirteenth modified example, the plate member 82 has a flat plate portion 120 and two bent portions 122. The flat plate portion 120 is a rectangular plate. A through hole 86 and a tongue portion 84 are formed in the flat plate portion 120. The two bent portions 122 are bent from the outer edge of the flat plate portion 120 in a direction perpendicular to the flat plate portion 120. The two bent portions 122 are bent toward the back side of the flat plate portion 120. The two bent portions 122 face each other in the protruding direction of the tongue portion 84. The tongue portion 84 is provided between the two bent portions 122. Specifically, the tongue portion 84 is provided in a region 123 between the two bent portions 122, which is surrounded by a dashed line. The linear member 70 is disposed on the tongue portion 84 along the protruding direction of the tongue portion 84 on the front side of the flat plate portion 120. Therefore, the linear member 70 is disposed on the tongue portion 84 without interfering with the bent portion 122.

In the thirteenth variant, even if the plate member 82 has two bent portions 122, the linear member 70 and the tongue portion 84 can be easily fixed together using the fixing device 100. Furthermore, the effects of this embodiment can also be obtained in the thirteenth variant.

[Fourteenth Modification]
11A , in the fourteenth modification, the two bent portions 122 of the plate member 82 are bent in directions perpendicular to the flat plate portion 120 at two adjacent sides of the flat plate portion 120.
