The invention relates to construction, to the manufacture of products from concrete mixtures. The purpose of the invention is to facilitate the removal of products with rectangular edges. FIG. 1 given form, general view in the assembled state; in fig. 2 - the same, in the position after separation of the compartments; in fig. 3 - the same at the time of stripping; in fig. 4 - product, view of the bending of the separation sheet; in fig. 5 shows section A-A in FIG. one.

The multi-sided form for the manufacture of products from concrete mixes contains a framing frame 1 mounted on a pallet 2, separator sheets 3 with a side-attachment forming the forming compartments with products 4. In the central part of the mold there is a rod 5 with stops 6 and the sheets 3 are missing the straps 7, on which the clamps 8 and the locking lugs 9 are mounted. The straps are a screw 10 interacting with the frame 1.

Multiple form works as follows.

In the assembled state, the separating sheets together with the borosnakstka form the molding compartments, in which concrete is placed and compacted by any of known methods (vibration pressing, deep compaction, vibratory plate, etc.). Fixed in the assembled state of the separation sheets 3 is carried out by the stops 9 on the stitches 7.

After heat treatment, the tray with the mold is installed on the demolding station. To dismantle the mold, it is necessary to unscrew the fastening screws (another method of transferring forces to the straighteners, such as a jack, may be used).

When unscrewing, the first grippers of 8 stj 7 are in contact with the perpagus. 2

the separating sheet opens the molding compartments from the subsequent sheet and withdraws them by the size of the opening 6 compartments, after which the second grippers enter 5 in contact with the second sheet, etc., until all the molding sections are separated from one another value 60.

In this case, all the sheets come into contact with the rests 6 of the rod 5 arranged accordingly. With the further extension of the shells, the middle part of the sheets abuts against the stops, and the sheets bend under the influence of the grippers. Here, as shown in FIG. 4, articles 4 are completely disintegrated. The mold is removed by the crank 5, and the items remain on the pallet 2.

The use of the mold allows to improve the quality of the manufactured products by providing standard geometrical dimensions and, due to effective stripping, to reduce labor intensity and increase labor productivity.
