Description

The invention relates to the building materials industry, in particular to devices for forming, extracting and transporting hollow glass products during their manufacture, and can be used in the glass industry.

The purpose of the invention is to increase the yield of glass products by eliminating their sticking to the matrix and mechanizing the process of their removal.

FIG. 2 shows a device, a general view in FIG. 2 — section A-A in FIG. 1 in FIG. 3 — section BB in FIG. 2, in FIG. 4 - form.

The device contains a horizontal power cylinder 1 attached to the central column 2, a press machine above the unloading position, a vertical power cylinder 3 rigidly attached to the rod 4 of the cylinder 1 and movably to the cylinder; it is 5, which in turn is fixed to the cylinder 1 and with the help of the slope 6 - to the fixed parts of the press machine. The extractor 7 is rigidly attached to the rod of the power cylinder 3, which corresponds in shape and dimensions to the internal cavity of glassware 8. The mold 9 for pressing glassware 8 contains a split matrix 10, body 11 and pallet 12, to the body 11 of each form 9 a horizontal guide 13 is attached, which can be made at the same time with the housing. The horizontal guide is located symmetrically with the plane of the die socket. Its working surface is located slightly below the level of the working surface of the pallet 12, in order to avoid impact of glassware when it is transferred from the pallet to the guide.

The level difference specified working surfaces is 1-3 mm. A value of less than 1 mm requires a high precision of manufacturing these parts j, and a value of more than 3 mm can cause undesirable large skews of glass products at the time of its transition from a pallet to a guide and consequence, their deformation.

In this case, it is desirable that the guide be located as close as possible to the pallet, i.e. Size a, characterizing the thickness of the matrix in the plane of the connector along the radial

the direction of the guide, go to zero.

However, if the size is too small, the operational qualities of the form deteriorate.

There is a local overheating of the thinnest portion of the matrix during the molding of the product and rapid cooling after removal of the product, which leads to tearing at the bottom of the product.

In the lower part of the die, on the side of the plane of the connector, grooves are made that surround the guide in the closed 5 position.

The device works as follows.

In the initial position, the extractor 7 is in the extreme upper position and its vertical axis coincides with the vertical axis of the forming part of the mold 9. This position is shown in Fig. 1 by solid lines. After the rotary table 14 of the press of the automatic machine 5 is stopped, the extractor 7 under the action of 3 is lowered into the internal cavity of the glassware, which is held in the center of the pallet 12 at the moment of opening the form 9.

0 open forms, cylinder 1 is activated, the rod 4 of which moves cylinder 3 to the right along guide 5.

The extruded product 8 is driven by the extractor 7 of the slit along the guide 13 and is installed on the receiving device 15. This position is shown in Fig. 1 by a dash line. As a receiving device, a conveyor, a swivel disk or another transport mechanism can be used, through which glassware is transferred for further technological operation, for example, for fire polishing of the surface.

D5 At the end of the stroke, 4 under. by the action of the cylinder 3, the extractor 7 leaves the inner cavity of the product, and the cylinder 1 BosBpaai.aeT returns to its original position. The operation of the units of the device is coordinated with the operation of the press by combining them with pneumatic or hydraulic systems controlled by one synchronizer (not shown).

Proposed for the construction of the device allows for the capture

products before the opening of the matrix, due to what is removed, its sticking to its flaps, providing a mechanical operation for the extraction of glass from the split matrix, which increases the yield of usable products and eliminates manual labor.
