Description

The invention relates to the production of water indicating glasses, for example, Klingers and Durance from molten glass, by vacuum forming and can be used for the production of other non-hollow glass products.

A device is known comprising a vacuum mold with an intake opening and a cavity repeating the configuration of the product, and a knife.

In order to improve the quality of the products in the proposed device, the intake opening is made with a cross section corresponding to the maximum size of the product, and the knife is mounted for movement relative to the intake opening.

FIG. 1 shows the proposed device, a longitudinal section; in fig. 2 - the mechanism of molding products in the work.

A device for forming water indicating glasses includes a frame 1, a feeder 2 and a head 3.

In the frame, a direct-current motor 4 and a gearbox 5 are installed. Transmission from the G:) Lectro-motor 4 to the gearbox 5 is carried out via a belt drive 6. A drive 8 with two cams 9 is attached to the output shaft 7 of the gearbox, which serve to switch the spool 10. On the output shaft of the gearbox has cylindrical shchestren

Y, which, by means of another gear 12 mounted on the shaft 13 of the bracket 14, rotates the disk 15. On the disk there are two cams 16, which

serve to drive the rocker / 7, transmitting movement to the air 18 and vacuum 19 valves.

Bracket 14 krenits to the frame. The motion from the cams to the valves 18 and 19 is transmitted.

through leverage 20.

Gear ratio of gears 11 and 12-1: 1. To the top of the frame krenits feeder,

It consists of two main parts: the base 21 and the sled 22. The base is a peg, sanding a platform at an angle of 15 ° to the horizon. The top of the platform serves as a bed for the sled and for fastening three

cylinders: working 23 and two buffer (not shown in the drawing). The slave cylinder communicates with the stem of the rod 24 a reciprocating motion, but to an arrow 25 (FIG. 2), a sled, and the buffer cylinders serve for

damping inertia sled.

Two pneumatic cylinders 26 of knife 27 are attached to the upper plane of the slide, connected with lever 28 and noMOHUi 29 with glass-forming knife 27 3. Lever

A doggie 31 is attached to the base of the 21 pntatel under the sled, and the stop 32 is above it, above the shaft.

The cylinders 26 are continuously supplied with compressed air in accordance with arrow 33.

The working cylinder 23 (Fig. 1) is equipped with a vacuum cylinder 34, which serves to continuously create a vacuum into the cavity of the mold 35 (Fig. 2) for a set of glass mass and compressed air to push the product 36.

Two sleeves are attached to the front cross-member 37 (Fig. 1) of the sled, which contain three end-Tube pipes.

The space between the inner 38 and the middle pipe is 39, as well as between the middle and the outer side. 40 pipes serve for the supply and removal of chilled water. The inner tube 38 is designed for vacuum and compressed air.

A head 5 is attached to the front rake 41 of the sleeves, which includes a housing 42 (FIG. 2) of the mold 35 and a knife 27. The mold 55 is fastened to the housing 42. Intuitively forms the cavity of 35, according to the configuration corresponding to the configuration of the water-glass, through the clamps 43 , the holes in the housing 42 and the pipe 38 (Fig. 1) are in communication with the vacuum cylinder 34.

The skin 27 (FIG. 2) is attached to the body 42 and has the ability to move relative to the intake opening of the mold 35, occupying successively three floor eti; 1 - the intake opening is openly partly (when glass melt is taken), II - the opening is completely closed (when cutting), III - the opening is fully open (product dispensing).

The device works as follows.

The DC motor 4 (Fig. 1) mounted on the frame, through the belt drive 6 and the gearbox 5, causes the disk 8 of the valve 10 to rotate, and through the cylindrical gear pair P and 12 - the disk / 5.

At the beginning of the operation of the device, the mechanisms of the feeder and the head capture the initial half-skein. Under the action of the following air flowing in the direction of arrow 44, the norm 45 of the working cylinder 23 retains: the sled 22 is in the leftmost (upper) position. The head 3 with the form 55 is located in the inlet furnace 46 nol 27 of the head 5 by means of the cylinder 26 is folded back, the intake opening of the form 55 is completely open (this is the floor: the snake in Fig. 2 is shown with a flat line). The clamps 18 and 19 are closed, and the vacuum cylinder 34 through the hole in the head 5 and the ishitsa 43 in the form 55 is in communication with the atmosphere.

When the disk 8 is rotated, the cam 9 and the switch;

under the piston 45 of the working cylinder 25 and moves the slide 22 with the head 5 forward. When moving the sled forward, the lever 28 of the knife 27, moving with the sled, presses the dog 31 and passes freely further. With a further slide, the upper end of the lever 28 of the knife 27 locates on the support 32, which is held apart on the frame, turns around the axis 30, moves

through knife 29 knife 27 forward. In this case, a space corresponding to the product configuration is formed by the form 55 and the full 27, and the slot of the knife 27 and v}, the morning edge of the form 35, forms a slot for the passage

glass melt at the time of its fence. In this position, the molds 55 and 27 enter the glass melt and are buried 4-5 mm into it.

By this time, the cam 16 of the valves 18 and 19 on the disk 15 opens the vacuum valve 19 and through the vacuum cylinder 34, the holes in the head 5 and the splines 43 in the form 55, the vacuum supplied to the installation and arrow 47 is transferred into the cavity of the form 55, closed from above by the form itself , and the bottom part of the knife 27 and glass melt. Absorbing the glass melt into the mold. This is the mechanism of the mechanisms in FIG. 2 Nokapao dashed line.

With further rotation of the disk 8 other

The cam 9 switches the spool 10 and the compressed air enters the pressurized cavity of the working cylinder 23, and the air under the pressure enters the atmosphere along the arrow 48. From the action of the ambient air, the slide begins to move back up. At the same time, the lever 28 of the knife 27 finds the dog 31 and, the air in the cylinder 26 is laminated, turns around the axis 30, and through the gun 29 gives the knife 27 forward.

There is a piece of the product from the glass. This position in FIG. 2 is shown with a dot-dotted line. Upon further movement of the slide, the lever 28 of the knife 27 is released from the pawl 31 and under the action of the cylinders 26

returns to the starting position.

Further rotation of the disk 15, the cam 16 switches the valve 18; Air is circulated into the vacuum cylinder and product 36 is ejected.
