Description

one

The invention relates to molds for the manufacture of products from concrete mixtures.

Known cassette forms for manufacturing reinforced concrete products are known, including the noddon and molding sections, mounted on a common frame 1.

The disadvantages of these cassette forms are that when removing items by lifting them up, mounting hinges are needed, and when the form is rolled out, tilting of items is difficult to remove.

Closest to the invention, the technical solution is a cassette for the manufacture of products from concrete mixtures, comprising a noddon, vertical separator sheets forming the forming compartments, and a plate chain connecting the separator sheets 2.

The disadvantage of this form is the pivotal attachment of the vertical separator sheets to the plate chain, which slows down the stripping and assembly of the forms.

The purpose of the invention is to ensure uniform opening of the molding compartments at the tank.

This is achieved by the fact that the chain plates are made with supporting edges that are in contact with each other, and are rigidly fixed on the separator sheets.

FIG. 1 shows schematically the proposed cassette form, a general view; in fig. 2 - the same at the time of stripping.

The cassette form is composed of noddoi 1, vertical separation sheets 2, forming molding compartments 3, lamellar values 4, the plates of which are rigidly fixed on the separation sheets 2 and are made with open edges 5. End plates 6

in chain 4 are made

with supporting edges 5 and 7 and hole 8.

Cassette form works as follows

in a way. In a working nozhozhenin dividing

sheets 2 are tightly closed. The cassette form with the reinforcement cages laid is filled with concrete, then the hydrothermal treatment of the products 9 in the mold is performed. For stripping, the elastic price 4 is raised

with a crane for the strips 8 end plates b, which, having rifled at a certain angle with their support faces 5 and 7, are in contact with the second and third plates of the chain 4, which also turning at the same angle

with its supporting edges 5, the fourth and fifth plates are involved in the work, and this is how it happens before IOLNO1-O opens all the molding compartments 3, while the products fall on the pallet under the action of their own weight.

The interaction of the support faces of the plates of the chain 4 ensures uniform and consistent disclosure of all the molding compartments 3 and ensures the absence of undisclosed 1x zones. The cassette form is brought into the working position by lifting the plate chain by the lugs in the middle parts (conventionally not shown).
