The invention relates to the manufacture of precast concrete and reinforced concrete products. The well-known form for the manufacture of products from concrete mixtures, which secures the hollow-forming anchor fixed on the pallet and the device for fixing it in the form of a conical leg and clamp, The closest to the proposed one is the form for the production of concrete mixes, which are mounted on the pallet side and slab. installed in its cavity by means of a fixture, an emptying device with an elastic sealing gasket 2. A disadvantage of the known devices is the difficulty of mounting the emptying MDL that povshaet complexity of adjustment required size forms on the article. The purpose of the invention is to reduce the labor capacity of the mold setting to the required size of the product. This goal is achieved by the fact that in the form for the manufacture of products from concrete mixtures, containing flanges mounted on the pallet and installed in its cavity by means of a fixture, a hollow core with an elastic sealing gasket, the core former is made with a wedge on the supporting surface, the fixing device is in the form of a rotary sptir in contact with the wedge stop and spaced in the segment slot formed in the body hollow core. Fig. 1 depicts a form for the manufacture of products from concrete mixtures, a general view; in fig. 2-section A-A in FIG. one; in fig. 3 - the form at the time of extraction of the finished product, the cross section. The form consists of a pallet 1, locking devices 2 and sides 3 with grooves 4. On one of the sides a hollow core 5 is mounted with a segment slot 6, a gasket 7 and a wedge support 8 on the supporting surface. A swivel pin 9 mounted on the axis 10 of the bracket 11 is mounted on the same side. The form for making concrete products works as follows. Before filling the mold with a concrete mixture, a rotary core 5 is installed on the rotary pin 9, the end of which passes through the groove 4 of the bead 3, provided with a gasket 7 on the side of the bead 3. Due to the elastic properties of the gasket 7 and the rotary pin 9 in contact with the wedge 8 and the groove edge And the bead 3, fixation of the hollow-forming agent on board 3 occurs. After the implementation of all technological operations related to the manufacture of a concrete product, namely, lubrication of the form, installation of the reinforcement cage, concreting and heat and humidity. processing, the stripping process is as follows. Using the locking devices 2, the forming surface of the beads 3 is separated from the surface of the product. When the finished product is removed, the puncher 5 with the surface of the segment slot b rotates the pivot pin 9 around the axis 10 of the bracket 1I, while the end of the pivot pin is retracted through the slot 4 inside the bead 3, thereby providing a free output of the poucher 5 with the finished product.
