Description

The invention relates to equipment for the manufacture of products from cementitious materials, in particular, to the design of molds for the manufacture of products from concrete, artificial stone, etc.

A known form for the manufacture of concrete products, including detachable metal snap-in, which houses a polymer liner (RF patent No. 2228262 B28B 7/36, publ. 05/10/2004). For products with different surface shapes, the liner is made integral.

However, the implementation of the composite polymer liner limits the range of manufactured products.

As a prototype, a form has been adopted for the manufacture of bulk products (USSR copyright certificate No. 1025517, B28B 7/22, publ. 02/18/1983). The mold contains a rigid base and walls (outer and inner formwork) of elastic material, for example, of sheet rubber. A liner is installed along the axis of the mold with diameter and height adjustable sectors interacting with the elastic inner formwork, and outside, screws interacting with the elastic outer formwork. Thus changing the shape of the elastic wall, shape the product.

However, this form can be used only for the manufacture of products such as bowls and it is difficult to ensure the exact shape of the product with mechanical regulators; deformation of sheet rubber in unintended places is possible. It is not intended to receive products with a pattern.

These shortcomings are eliminated by the proposed solution.

The task at hand is the creation of a universal, simple in design form for mass production of products, for example, facade, asphalt and other tiles, artificial stone.

EFFECT: expansion of technological capabilities of forms due to simplification of installation with high surface quality: glossy, embossed and with a pattern.

This technical result is achieved in that in the mold for the manufacture of products from cementitious compositions containing a rigid base and walls of elastic material, the walls are made of vulcanized rubber with a shaping surface of various configurations and embossments corresponding to the molded product, and

glued the bottom surface to the polymer plate mounted on the base on which the drawing is reproduced on the front surface of the manufactured product, a pressure plate is installed on the upper surface of the wall to form the back surface of the product.

The implementation of the walls of vulcanized rubber provides a combination of a low degree of elasticity and sufficient rigidity, in contrast to the sheet rubber in the prototype, to ensure the configuration of the form. Gluing the walls to the polymer plate makes it easy to remove and replace the walls and plate depending on the desired configuration and pattern on the front side of the product. In this case, the walls, in comparison with the prototype and existing forms, are broadened to the size of the molded product, which allows to improve the contact of the pressure plate with the form and the mass poured into it.

The proposed form is shown in the drawing.

It contains a rigid base 1 and wall 2 of vulcanized rubber. The walls 2 are broadened and have a forming surface 3, corresponding in shape and relief to the molded product, and glued with the lower surface 4 to the polymer plate 5 installed in the cutout of the base 1, on which, for example, by thermal vacuum molding, a pattern is reproduced that is reproduced on the front surface of the product . On the upper surface 6 of the wall 2, a pressure plate 7 of corrugated glass is installed, forming the back side of the product.

The form is collected as follows.

A polymer plate 5 is mounted on the rigid base 1. The bottom surface 4 of the wall 2 is glued to the plate 5. The mold is mounted on a vibrating plate, filled to the upper edge with the composition from which the product will be made. Close the pressure plate 7. The composition hardens at room temperature. The formwork is carried out in the reverse order. Remove the pressure plate 7. The mold with the product is removed from the base and the product is removed. With a curly side surface of the product, a transverse shape connector may be provided.

The product is easily separated from the polymer plate 5 and the walls 2, because they have little adhesion to the composition.

The proposed form can be used for mass production of products with the texture of natural stone with a polished surface, given the relief and pattern.
