Description

The invention relates to the building materials industry and can be used to manufacture perforated gypsum boards. A device for the manufacture of perforated gypsum boards, including a base, a slab with hollowers, a perforated tray, flaps, mounted on carriages 1 is known. The disadvantage of this device is that it contains a large number of interacting mechanisms and parts and is not reliable in the work The closest to the invention is the form for the manufacture of gypsum sound bars, ayushi plates, containing a movable pallet mounted on the base with the composition of the board equipment, the insert and a bracket connected to the hinged lid, secured on the latter with an elastic mat with punches 2. However, this construction does not allow the elastic mat with punches to be pulled away from the molded product and when the lid is opened, its front surface is destroyed. When demoulding, the product is not uniformly pushed out of the mold, which leads to the formation of cracks in the slab. The purpose of the invention is to improve the quality and convenience of dismantling products. The goal is achieved by the fact that in the form for the manufacture of gypsum sound-absorbing plates containing a movable base mounted on the base with a composite board, an insert and a bracket connected to a hinged lid fixed on the last elastic pad with punches, each piece of the board provided is made of contacting inclined surfaces and spring-loaded one relative to the other sections with stops, one of which is fixed on the pallet, and the bracket with a guide groove for accommodating the axis of the hinge cap and is connected via a further scharnira with a base. Ha FIG. 1 shows a mold for making sound-absorbing gypsum boards, a slit; in fig. 2 - node I on an enlarged scale; in fig. 3 - the form is closed in a horizontal position; in fig. 4 - the form in horizontal position, a section is opened; in fig. 5 - the form when removing the product, the cut; in fig. 6 version of the mold design for the manufacture of plates with double-sided perforation. The form consists of a pallet 2 mounted on a base 1 with a bracket 3, a hinged lid 4, a liner 5 and a boring equipment, which is made up of sections 6 contacting with inclined surfaces with stops 7 and sections 8, spring-loaded by means of elastic elements 9 relative to sections 6. Bracket 3 is made with a groove 10 in which the pivot cover hinge 11 moves. On the base 1, an additional hinge 12 is mounted to secure the mold to the base 1. A hinged mat 13 with punches is fixed on the hinged lid 4 on the inside of the mold 14. On the base 1, stops 15-17 are installed, which are in contact with the bracket 3, the lid 4 and the bar 18 mounted on a pallet 2, respectively. The form is provided with locks. Y v i anv Uiiv-ii lh / gd The form works as follows. Before pouring the sludge, the hinged lid 4 is tightly pressed to the aircraft equipment of the pallet 2 and secured with locks, while the hinge 11 of the hinge of the cover 4 is offset in slot 10 to the pallet 2, and the movable sections of the aircraft 8 squeeze the elastic elements 9 and slide inside the form to form a cell for pouring sludge. The mold is in a vertical position and fixed by a hinge 12 of the base and an anvil 15. Gypsum slurry is poured through the open cavity of the mold and after the disassembly strength of the product is reached, the mold is opened. The entire shape rotates around the hinge 12 and the horizontal position of the jy is fixed by the strap 18. When opening the locks, the hinged lid 4 goes down flat-parallel to the pallet 2 and locks in this position by the stop 16 and the hinge axis 11 moving along the notch 10 to the elastic element 9 section 8 of the relatively non-movable sections 6 up to the stop 7, the outer surface of the sections 8 moves away from the product 19, forming a gap and the product 19 under its own weight remains on the lid 3 of the spacer. turns the arrows around the hinge 12 to an upright position until the bracket 3 interacts with the stop 15. The cover 4 with the product slides along the roller stop 16. t-j j t-j and remains in an inclined position. The product 19 lying on the lid 4 is removed, the mold is cleaned and lubricated. The pallet 2 rotates clockwise around the hinge 12 of the anvil 17, the lid 4 moves to the pallet 2 and is locked with locks, squeezing the movable sections 8, and rotates to its original position around the hinge 12 until it stops 15. The next plaster sludge is filled. If it is necessary to manufacture plates with double-sided perforation and an internal friction layer on the pallet, instead of the liner 5, a mat 20 is attached with a poise 21. When the mold is opened, a mat 13 with punches 14 fixed on the lid 4 is laid on the friction layer 22 (base, single, gauze, etc. ), the form is closed. And all subsequent operations are performed as described above.

The proposed form excludes the operation of pushing the product out of the mold, which

improves the quality of the product and further the possibility of automating the process up to the automatic demoulding of products.
