Abstract

The invention relates to the production of building products with voids by molding. The purpose of the invention is to increase reliability. A device for forming building products with voids contains a base 1 mounted on a base 2, a vertically movable cross beam 4, an intermediate cross bar 9 with pressing elements 10, and a multi-bed matrix 19. At the ends of the cross bar 9, detachable housings 13 are fixed, each of which is made facing each other wedge surfaces with guides and wedges 16 installed on the last with 17 t, 17, on the free ends of which are placed the stoppers 18 interacting with the crossmember 4.

F. I

The invention relates to the production of building products with voids by the molding method.

The purpose of the invention is to increase reliability.

FIG. 1 shows a device for forming building articles with voids, a general view; 2 is the same at the time of pressing; in fig. 3 - the same, at the time of the rise of the matrix; in fig. 4 - the same, at the time of release of the product; in fig. 5 is a section A-A in FIG. 2; FIG. 6 is a view B in FIG. 3; in fig. 7 is a view of B in FIG. five.

A device for forming building products with voids comprises a frame 1 mounted on a base 2, a drive 3 mounted on a frame for vertical movement of a movable cross member 4 with swiveling grippers 5 having hooks 6 and 7 mounted on the latter by means of supports 8 intermediate cross member 9 with pressing elements 10, carrying hollow cores 11, vibration exciters 12 are installed on the intermediate cross member 9, and at both its ends there are detachable covers 13, each of which is made with wedge facing FRIEND to a friend overhnost E forming the expandable upwardly open groove 14 with the guide 15, on which the wedges 16 are installed with the connecting rods 17. The latter have at the free ends of the guides 18, cooperating with the movable crosspiece 4 in its upper position. Under the pressing elements 10, on base 2, a multi-bed matrix 19 is provided, equipped with stops 20, which cooperate with hooks 7. On the bed 1 there is fixed a hopper 21 for loading the concrete mix and two flat protrusions 23 in contact with the wedges 16 in the lower position of the cross member 4.

The device works as follows.

I

In the initial position of the matrix 19

mounted on base 2, and carrying the yoke 4 is raised to the upper position. In this case, the intermediate yoke 9 with its supports 8 rests on the hooks 7 of the swiveling grippers 5, and the tippers 17 with their stoppers 18 rest on the carrier yoke 4, with the result that the wedge 16 is somewhat raised and moved apart by

the tracks along the guides 15 in the upwardly opening open slots 14.

In this position, from the bunker 21, the concrete mixture 22 is placed in the matrix 19 and the open surface is leveled and the excess mixture is removed. After the matrix is filled with the mixture by means of the actuator 3, the movable yoke 4 is lowered, resulting in the simultaneous lowering of the yoke 9 with the pressing elements 10 and with the two covers 13. When the spread wedges 16 of each cover 13 reach the flat protrusion 23 and the formers 11 are lowered onto the concrete mix 22, include exciters 12. As a result, the latter are quickly immersed in the concrete mix to a position where the pressing members 10 are lowered onto the mix and compact it. With this, the intermediate yoke 9 stops and the t-reverse 4 is lowered.

When lowering, the traverse 4 is detached from the stops 18, with the result that the wedge 16 under its own weight and the action of the vibration lowers, i.e. In the zone of narrowing of the grooves 14. In this case, the wedge 16, moving along the guides 15, comes into close contact with the flat protrusions 23 and engages it with the covers 13 and through the two protrusions 23 fastens both ends of the intermediate yoke 9 with the frame 1. When the yoke 4 is lowered onto the yoke 9, the claws 5 are rotated to the position in which the hooks 6 rotate beyond the supports 8, and the hooks 7 engage with the lugs 20 of the matrix 19. Then, by means of the actuator 3, the carrier yoke 4 is lifted, resulting in hooks 7 raise the matrix 19 "With this product 24 I hold with the elements 10, as at the moment the pressing elements 10 are fixed relative to the frame 1 and driven 3 are in the closed system frame. Consequently, the resulting friction forces between the walls of the die and the products 24 through the grippers 5 are transmitted to the actuator 3 (lifting the mold) and are balanced by the pressing elements 10, which, like the actuator 3, are also bonded to the frame.

When the dies 19 rises above the products 24, and the carrying bar goes up to the stoppers 18, the gigs 17 raise the wedge 16 upwards to the expanding

part of the groove 14, as a result of which the wedge releases the flat protrusions 23 and the yoke 9 from the bed 1. In this case, the matrix rises under the yoke 9 and ensures its lifting, removing the pressing elements 10 from the products and removing the forming elements 11 from the voids 25. The finished products are removed and the cycle repeats.
