Description

1

The invention relates to construction and can be used to make hollow concrete products.

The purpose of the invention is to improve the quality of products by increasing the accuracy of their reometric dimensions and increasing reliability.

FIG. 1 shows a general view of the mold during the molding process; FIG. 2 shows section A-A in FIG. one; in fig. 3 shows a section BB in FIG. one; in fig. 4 shows a section B-B in FIG. 3

The device comprises a matrix 1 consisting of rigidly interconnected longitudinal and transverse sides. In the lower part of the matrix 1, the supporting elements 2, located discretely (discontinuously), are fixed on them in the inner surface. Inside the matrix 1, there are holders 3 with vibration exciters 4 horizontal oscillations. The supporting elements 2 are made with horizontal mounting slots 5, and the core holders 3 have centering lugs 6 installed in these grooves 6. Each hollow 3 has a recess 7 located along its perimeter with an elastic gasket 8 placed in it.

The device is equipped with a vertically movable figure pallet 9 and a punch 10. Pallet 9 is supported on supporting elements 2 of matrix 1, and punch 10 is made with stops 11 and protrusions 12 and 13, of which protrusions 12 are placed between matrix 1 and holders 3. and protrusions 13 between hollow bridges.

Punch 10 stops 11 contact the upper end of the matrix t. Punch TO vertically move the press (not shown). The finished product is pressed out using a pusher 14, having 2 rods 15 located between the supporting elements 2, which are in contact with the pallet 9. The concrete mixture is fed into the molding cavities, for example, from a hopper.

The device works as follows.

Before feeding the mixture into the molding cavities, the punch 10 is pulled out of the device. The device is clean, greased, and then out. bunker serves concrete mix. After filling the molding cavities with the concrete mix, vibratoyr 4 of the emptying formers 3 is turned on, and within 10 seconds they evenly distribute the concrete mix,

after which the vibrators are turned off. Next, the punch 10 is installed in the device so that the projections 12 and 13 enter the concrete mix, after which a press is turned on, which moves the punch 10 down until the lugs 11c touch the upper end of the die 1. After that the press is turned off. The concrete mix is compacted to the required value, after which the punch 10 is removed from the device.

The freshly molded product is removed as follows.

The pusher 14 is turned on and, moving vertically upwards, pushes the pallet 9 with the product by means of rods 15 to the upper level of the matrix 1, after which the product is removed, for example, by means of a manipulator, and transferred to the trolley. The pallet 9 is lowered by the pusher 14 with the rods 15, and the process is repeated.

In the proposed device, it is possible to manufacture products of exact geometric dimensions, and the device itself has greater reliability.

Claims (2)

1. A device for the manufacture of blocks with voids from a concrete mixture containing a matrix of interconnected transverse and longitudinal sides with a vertically movable figure pallet, a punch, a drive pusher, void-forming agents and vibration exciters, in order to improve quality products by increasing the accuracy of their geometrical dimensions and increasing reliability, the sides are equipped with supporting elements rigidly fixed in the lower part of their inner surfaces with horizontal elements t Basically, the core holders are made with centering protrusions installed in the latter and with perimeter depressions with resilient pads placed in them, the punch with stops in contact with the upper end of the matrix, while the beads are interconnected rigidly and the drive pusher has intersections between the supporting elements rods in contact with the figure pan. 2. The device according to claim 1, characterized in that, in order to increase the efficiency of compaction of the concrete mix, the exciters are placed inside the core holders so that their disturbing force is directed horizontally.
