Description

The proposed materials of the application relate to the field of manufacture of decorative building parts, for example, facing textured boards with various dimensions, reliefs and geometric shapes.

There are various options for molded tooling and technological devices for the manufacture of decorative building parts and blanks used to obtain decorative products from cement-containing and gypsum-containing solutions.

The known form, consisting of a pallet, walls, fasteners, factoobrazuyuschimi parts and the mechanism for disassembling equipment. (Chernykh V.F. Wall and decoration materials M. RosAgroPromizdat 1991). Similar units also has a form for concrete products (AS USSR 435112). The technical disadvantages of such forms are the complexity of the design, the duration of disassembly and assembly, inconvenience in operation.

The known form proposed in the patent of the Russian Federation No. 80876 for a utility model. The form contains a pallet, walls, fasteners and an additional screw device for moving the pallet. The pallet is movable and equipped with a removable seal that prevents the penetration of the liquid solution into the lower part of the mold, where the screw device is located. However, it is not possible to obtain a variety of decorative building parts using the form, including several different parts at the same time.

This form was adopted as a prototype, as the closest to the proposed technical solution.

The technical task of the claimed materials is to create a form that allows the simultaneous manufacture of several products, including those with complex decorative surface texture.

The solution to the technical problem is achieved by the fact that the form containing the pallet made movable, the walls, the fasteners, the screw device that drives the pallet in motion and the sealing system additionally contains a form-forming whole insert based on an elastic composite polymer material, resting flat bottom on the plane of the pallet, adjacent lateral edges to the structural walls of the mold and covering the upper edge of the structural walls of the mold, covering with shaped protrusions of its upper part.

The proposed design is illustrated in figure 1 - figure 3.

The inventive form consists of structural walls 1 inside of which there is a pallet 2 and a screw device 3 driving it. Inside the form there is also a whole textured insert 4 with a factor-forming surface 5. The insert 4 rests with its flat bottom on the plane of the pallet 2, and the shaped protrusions 6 with its own the upper part covers the upper edge of the structural walls 1 of the form. Factor-forming surface 5 can be divided into sections by partitions 7 cast at the same time with insert 4.

Thus, the walls of the mold, in combination with the pallet, perform the function of a tank with a movable bottom, inside of which there is a whole insert that acts as a replaceable functional forming element.

Depending on the set dimensions of the manufactured products and the desired mold performance, the geometric dimensions of the mold and pallet can vary widely.

The form works as follows. In the operating position, using the screw device 3, the pallet 2 is lowered so that the flat bottom of the rear insert 4 rests completely on its plane, and the protrusions 6 of the rear insert 4 cover the upper edges of the structural walls 1. Due to the elasticity of the material, the lateral edges of the insert 4 are tight adjacent to the structural walls 1 from the inside.

Use the mold in this way.

The form is filled to the required height with a cement-containing or gypsum-containing solution of the required composition, color, and consistency. Expose to cure. Before filling or during filling, technologically necessary fittings can be installed (not shown in the figure). In the presence of partitions, it is possible to simultaneously fill sections with various materials.

After curing the composition with a screw device 3, the insert 4 with molded products is lifted to the required height. The obtained products are removed and insert 4 is returned to its original working position, lowering the tray 2. When changing various inserts in this mold size, a wide range of various decorative parts and products can be obtained, the thickness of which is regulated by the degree of filling of the insert with the solution. The thickness of the products in sections may be different.

This application is illustrated by the following examples.

Example 1

A form is made for the manufacture of decorative and building products containing a whole insert made of polyurethane. The surface of the whole insert imitates chipped marble and is not divided into sections for various products. Products are cast from a mixture with the addition of white cement and pigment. After the mixture has cured, the whole insert with the pallet is lifted to the upper edge of the mold using a screw device and the molded product is removed from the whole insert. The pallet is returned to its original position, and the whole insert is placed inside the form, the facto-forming surface of which covers the edges of the structural walls with its upper part.

Example 2

A mold has been made for the manufacture of decorative and building products containing an entire insert made of silicone rubber, a surface imitating the texture of slate and divided into four identical rectangular sections. The mold is poured with a cement-containing solution filled with a mixture of sands of various fractions.

After the mixture has cured, the whole insert along with the pallet is lifted to the upper edge of the mold using a screw device and molded products are removed from the whole insert. The pallet is returned to the initial deposit, and the whole insert is placed inside the mold, pressed against the structural walls of the mold with its edges, and covering the upper edges of the walls with shaped protrusions.

Example 3

A mold is made for the manufacture of decorative and building products containing a whole insert made of a rubber mixture based on a hydrocarbon base with a surface simulating the texture of chipped limestone and divided into five sections of irregular shape. The mold is poured with a cement-containing solution filled with a mixture of sand of various fractions with the addition of yellow and orange pigments.

After the mixture has cured, the whole insert with the pallet is lifted to the upper edge of the mold using a screw device and the molded product is removed from the whole insert. The pallet is returned to the initial deposit, and the whole insert is placed inside the form.

Example 4

A mold has been made for the manufacture of decorative and building products containing a whole insert made of polyvinylchloride plastisol for the surface imitating the texture of chamotte and divided into several sections of irregular shape. The extraction is similar.

Example 5

A mold is made for the manufacture of decorative and building products containing a whole insert made of thermoplastic elastomer with a surface imitating a granite surface and divided into four different rectangular sections with chamfers at the edges. Fill with a standard cement mortar filled with granite screenings, the desired shade. The extraction is similar.

Thus, the proposed design, namely, an additional molded whole insert, having, from one to several compartments for filling with a solution, located on a pallet, adjacent to the side walls of the form and covering the shaped edges of the upper edge of the walls of the form is new and unknown from the prior art.

Thus, the task has been achieved - a form has been created that allows the simultaneous manufacture of several products, including those with a complex decorative surface texture, which makes it possible to produce products of an expanded assortment due to the quick readjustment of the whole inserts.

The form proposed for consideration was designed, manufactured and tested under the conditions of the pilot production of Technological Equipment OJSC in St. Petersburg. This form has allowed to increase the productivity of the manufacturing process of building forms with a greater variety of types of products.

The applicant asks to consider this application for the grant of a patent of the Russian Federation for a utility model.
