In the following description, reference is made to or is described with reference to certain drawings for emphasis only on the description that follows, but without limitation to the description that follows, reference is made to these drawings for the most part.

Referring to fig. 1 to 3 together, fig. 1 is a schematic view of a temperature adjustment member according to an embodiment of the present invention, fig. 2 is a schematic view of a body and a first channel of the temperature adjustment member according to the embodiment of the present invention, and fig. 3 is a schematic view of the body and a second channel of the temperature adjustment member according to the embodiment of the present invention. The temperature adjustment member 100 according to an embodiment of the present invention is suitable for being disposed on a molding machine (such as, but not limited to, various injection molding machines). The temperature adjustment member 100 includes: a body 10, a first channel 11 and a second channel 12. The body 10 has a first end 10A and a second end 10B opposite to each other. The first passage 11 is formed in the body 10, and the first passage 11 is formed with a first inlet 111 and a first outlet 112 in the body 10. A fluid entering the first channel 11 from the first inlet 111 will be guided by the first channel 11, flow from the first end 10A to the second end 10B of the body 10, and leave the body 10 from the first outlet 112.

The second channel 12 is formed in the body 10, the second channel 12 is not communicated with the first channel 11, and the second channel 12 is formed with a second inlet 121 and a second outlet 122 on the body 10. Fluid entering the second channel 12 from the second inlet 121 will be guided by the second channel 12, flow from the second end 10B to the first end 10A of the body 10, and exit the body 10 from the second outlet 122.

In practical applications, the first inlet 111 and the second inlet 121 may be formed adjacent to each other on the body 10, and the body 10 may further have a first groove 101, and the first inlet 111 and the second inlet 121 can communicate with each other through the first groove 101. The first groove 101 may be used to provide a fluid supply member for fixing, or fluid may flow into the first groove 101 and enter the first channel 11 and the second channel 12 through the first inlet 111 and the second inlet 121. Similarly, the first outlet 112 and the second outlet 122 may be formed adjacent to each other in the body 10, and the body 10 may further have a second groove 102, and the first outlet 112 and the second outlet 122 can communicate with each other through the second groove 102. The second groove 102 may be, for example, for securing the fluid recovery mechanism to one another.

The fluid flowing through the first and

second passages

11 and 12 can exchange heat with the body 10. In practical applications, according to requirements, a high temperature fluid or a low temperature fluid flows into the first channel 11 and the second channel 12 from the first inlet 111 and the second inlet 121, and the high temperature fluid or the low temperature fluid flows in the body 10 along the first channel 11 and the second channel 12, and finally exits the body 10 from the first outlet 112 and the second outlet 122, and during the process that the fluid flows in the body 10 along the first channel 11 and the second channel 12, the fluid exchanges heat with the body 10, and the temperature of the body 10 is increased or decreased accordingly.

FIG. 2 is a schematic diagram of a first channel of a temperature adjustment component according to an embodiment of the invention; for the sake of clarity, the first channel 11 is not shown in fig. 2, and the second channel 12 is not shown. In this embodiment, the first channel 11 may include a first straight section 113 and a first spiral section 114, one end of the first straight section 113 is connected to the first inlet 111, the other end of the first straight section 113 is connected to the first spiral section 114, and the other end of the first spiral section 114 is connected to the first outlet 112.

Fluid entering the first channel 11 from the first inlet 111 will flow along the first straight section 113 from the first end 10A of the body 10 to the second end 10B of the body 10, and then fluid entering the first spiral section 114 will flow along the first spiral section 114 from the second end 10B of the body 10 to the first end 10A of the body 10. During the process of the fluid flowing in the first channel 11, the fluid exchanges heat with the body 10, thereby increasing or decreasing the temperature of the body 10.

It is worth mentioning that the total length of the first straight section 113 may be less than the total length of the first spiral section 114, that is, the time required for the fluid to pass through the first straight section 113 is less than the time required for the fluid to pass through the first spiral section 114 at the same flow rate. In various embodiments, the volume of the first channel 11 in the first straight section 113 may be smaller than the volume of the first channel 11 in the first spiral section 114, and the time required for the fluid to pass through the first channel 11 is shorter than the time required for the fluid to pass through the first spiral section 114.

FIG. 3 is a schematic diagram of a second channel of a temperature adjustment member according to an embodiment of the invention; for the sake of clarity, the second channel 12 is not shown in fig. 3, but the first channel 11 is not shown. In the present embodiment, the second channel 12 includes a second straight section 123 and a second spiral section 124, one end of the second straight section 123 is connected to the second outlet 122, the other end of the second straight section 123 is connected to the second spiral section 124, and the other end of the second spiral section 124 is connected to the second inlet 121. Fluid entering the second channel 12 from the second inlet 121 can flow along the second spiral section 124 from the first end 10A of the body 10 to the second end 10B of the body 10, and then fluid entering the second linear section 123 will flow along the second linear section 123 from the second end 10B of the body 10 to the first end 10A of the body 10. During the process of flowing in the second channel 12, the fluid exchanges heat with the body 10, thereby raising or lowering the temperature of the body 10.

It is worth mentioning that the total length of the second straight section 123 may be less than the total length of the second spiral section 124, that is, the time required for the fluid to pass through the second straight section 123 is less than the time required for the fluid to pass through the second spiral section 124 at the same flow rate. In various embodiments, the volume of the second channel 12 in the second straight section 123 may be smaller than the volume of the second channel 12 in the second spiral section 124, and the time required for the fluid to pass through the second channel 12 is shorter than the time required for the fluid to pass through the second spiral section 124. The shapes and sizes of the first straight section 113, the first spiral section 114, the second straight section 123 and the second spiral section 124, the pitch and the rotation direction of the first spiral section 114, and the pitch and the rotation direction of the second spiral section 124 can all be changed according to actual requirements, and are not limited to those shown in the drawings of the present embodiment.

Referring to fig. 1 and 4 together, fig. 4 is a partial cross-sectional view illustrating a temperature adjustment member according to an embodiment of the invention. In practical applications, the first spiral section 114 is spirally formed in the body 10 around a central axis C, and the second spiral section 124 is spirally formed in the body around the same central axis C. The first spiral section 114 and the second spiral section 124 are formed in the body 10 in a staggered manner.

When the fluid enters the first channel 11 and the second channel 12 from the first inlet 111 and the second inlet 121, respectively, a portion of the fluid will flow from the first end 10A of the body 10 to the second end 10B of the body 10 along the first straight section 113 of the first channel 11, and another portion of the fluid will flow from the first end 10A of the body 10 to the second end 10B of the body 10 along the second spiral section 124 of the second channel 12. During the process that part of the fluid in the second channel 12 flows from the first end 10A of the body 10 to the second end 10B of the body 10 along the second spiral section 124, another part of the fluid in the first channel 11 synchronously passes through the first straight section 113, enters the first spiral section 114 and flows from the second end 10B of the body 10 to the first end 10A of the body 10 along the first spiral section 114.

That is, the fluid flowing into the first channel 11 flows from the first end 10A of the body 10 to the second end 10B of the body 10 in a relatively short time, and then flows from the second end 10B of the body 10 to the first end 10A of the body 10 in a relatively long time; in contrast, the fluid flowing into the second channel 12 flows from the first end 10A of the body 10 to the second end 10B of the body 10 for a relatively long time, and then flows from the second end 10B of the body 10 to the first end 10A of the body 10 for a relatively short time.

As described above, by the design of the first straight section 113, the first spiral section 114, the second straight section 123 and the second spiral section 124, a part of the fluid flows from the second end 10B of the body 10 to the first end 10A of the body 10 along the first spiral section 114 at the same time, and another part of the fluid flows from the first end 10A of the body 10 to the second end 10B of the body 10 along the second spiral section 124, so that the temperature of the whole body 10 can be uniformly raised or lowered.

For example, assuming that the fluid is a 5 degree cooling fluid, the temperature of the 5 degree cooling fluid entering the first channel 11 from the first inlet 111 and located at the first end 10A of the body 10 may only rise by 5 degrees after passing through the first straight section 113 and located at the second end 10B of the body 10, and then the 10 degree cooling fluid will flow along the first spiral section 114 from the second end 10B of the body 10 to the first end 10A of the body 10; meanwhile, the cooling fluid of 5 degrees entering the second channel 12 from the second inlet 121 and located at the first end 10A of the body 10 flows from the first end 10A of the body 10 to the second end 10B of the body 10 along the second spiral section 124, the temperature of the cooling fluid flowing to the second end 10B of the body 10 may only rise by 5 degrees, and then the cooling fluid of 10 degrees flows from the second end 10B of the body 10 to the first end 10A of the body 10 along the second straight section 123. That is, at the same time, the cooling fluid of 10 degrees and the cooling fluid of 5 degrees flow from the second end 10B of the main body 10 and the first end 10A of the main body 10 to the other end of the main body 10, respectively, so that the second end 10B of the main body 10 and the first end 10A of the main body 10 have similar heat exchange degree and cooling rate, and all parts of the main body 10 are simultaneously cooled by the cooling fluid of relatively low temperature, so that the whole main body 10 is uniformly cooled, and the cooling space can be shortened.

The cooling fluid passing through the first straight section 113 and located at 10 degrees at the second end 10B of the body 10 gradually increases in temperature while flowing from the second end 10B of the body 10 to the first end 10A of the body 10 along the first spiral section 114, and the cooling fluid has a higher temperature closer to the first end 10A of the body 10, that is, the cooling fluid in the first channel 11 has less heat energy to take away from the cooling fluid during flowing from the second end 10B of the body 10 to the first end 10A of the body 10; the cooling fluid flowing along the second spiral section 124 at 5 degrees gradually increases in temperature from the first end 10A of the body 10 to the second end 10B of the body 10, and the cooling fluid has a higher temperature closer to the second end 10B of the body 10, i.e., the cooling fluid in the second channel 12 can carry less heat energy from the flowing of the cooling fluid from the first end 10A of the body 10 to the second end 10B of the body 10.

In the prior art, a single cooling channel is formed in a stub bar of a part of injection molding machines, and after entering from an inlet of the cooling channel, a cooling fluid flows from a first end of the stub bar to a second end of the stub bar and then flows back to the first end of the stub bar from the second end of the stub bar. Further, the cooling fluid at the first end of the stub bar is relatively low temperature, while the cooling fluid at the second end of the stub bar is relatively high temperature, and the heat exchange degree of the first end and the second end of the stub bar is different, so that the whole stub bar cannot be uniformly cooled.

The first channel 11 is not in communication with the pouring channel 13 and the second channel 12 is not in communication with the pouring channel 13. The pouring channel 13 is used to provide a material (such as fluid plastic) to pass through. In one embodiment, the pouring channel 13 may be disposed through the body 10 along the central axis of the body 10, and the first spiral section 114 may be spirally formed in the body 10 centering on the pouring channel 13, while the second spiral section 124 may be spirally formed in the body 10 centering on the pouring channel 13, and the first spiral section 114 and the second spiral section 124 are formed in the body 10 around the pouring channel 13 with being offset from each other.

The mold B comprises two mold plates 20, each mold plate 20 has a groove 201, the two mold plates 20 can be engaged with each other, and the two grooves 201 can form a mold cavity together.
