Abstract

Use: manufacture of building products used in ceilings and wall cladding. SUMMARY OF THE INVENTION: The device comprises a form fixed to the frame, composed of a base with sides, an insert and ejector devices, covers with a cavity blocked by a diaphragm, and an elastic mat with punches. New in the device is the placement of the form vertically and attaching the vibrator to the bottom in such a way that the plane of action of its disturbing force coincides with the plane passing through the vertical axes of the spring shock absorbers and the center of gravity of the form, on the top side of which grooves are formed, and the punches are elastic The cinnamon is made a height of 1.04 to 1.06 times the distance between the liner and the carpet. 3 il.

WITH

The invention relates to the process equipment used in building materials enterprises and is intended for the manufacture of building products.

The aim of the invention is to increase the productivity and quality of products.

FIG. 1 shows a general view of a device for the manufacture of gypsum sound absorbing plates; FIG. 2 - the node in FIG. 1 in section, in FIG. 3 is a view along arrow A in FIG. one.

The device contains a vibrator 1, spring dampers 2 and a form consisting of a base 3 with an upper 4 and side 5 sides, an insert 6, an ejector 7 of products, a cover 8 with a cavity blocked by a diaphragm 9, and an elastic mat 10 with punches 11. The shape is provided with frame 12

and installed vertically on the spring shock absorbers 2, the cover 8 with a cavity - with cap locks 13 and is hinged to the form. The upper bead 4 on the side of the elastic mat 10 is made with evenly spaced along the length of the molding cavity by the slots 14 for air outlet. The vibrator 1 is made in the form of a directional vibrator, in which the direction of its disturbing forces is aligned with the plane of the axes of the spring shock absorbers 2 and the center of gravity of the form. The punches 11 of the elastic mat 10 are made with a height of 1.04., 1.06 times the distance between the liner 6 and the mat 10. The liner 6 is formed by the diaphragms 15, with which the ejector 7 of the products contacts.

About

The device works as follows.

Clean and lubricate the mold work surfaces. Close the lid 8 and fix to the base 3 with locking locks 13. Compressed air is supplied to the lid space 8, under the action of which the diaphragm 9 presses the punches 11 of the mat 10 to the surface of the liner 6. The pressure is set so that the punches 11 are compressed to the size corresponding to plate thickness. At the same time, the punches 11 increase in diameter and simultaneously act on the insert 6, reduce its thickness and increase the length and width, i.e. dimensions on the ends.

A vibrator 1 is turned on and a gypsum mix is poured into the prepared mold through a hole in the top board 4. In the process of vibration, the plaster mix evenly fills the mold and compresses, and the air leaves the mold through the slots 14. As soon as the gypsum mix begins to seep through the slots 14, stop pouring and turn off the vibrator 1.

After the process of hardening the plaster mix in the cavity of the cover 8 is released, the pressure is released. In this case, the compressive load is removed from the punches 11, and they, aspiring to restore their original shape, decrease in diameter, and the insert 6 decreases in true length and width and increases in thickness, i.e. restores its original shape, contributing to the best separation of the mat 10 from the product. Then, the overhead locks 13 are opened, the lid 8 is retracted and together with it the mat 10 is smoothly removed from the perforated screen of the molded plate. Next, using the ejector 7, the product is released from the liner 6 and removed from the mold.
