RU2795294C1 - Brick mould with rhombic pyramids and pyramidal recesses on the body - Google Patents

Abstract

FIELD: pressing; manufacture of bricks.

SUBSTANCE: mould contains a clip and located in it the lower and upper half moulds. The lower half mould is made with three planes having pyramidal recesses for forming rhombic pyramids on the brick body. The upper half mould is made with three planes having pyramids to form pyramidal recesses. The holder and the upper and lower half moulds are made with the possibility of moving the half moulds inside the holder along the longitudinal axis of the brick at an angle of 45° to the horizontal plane.

EFFECT: it is possible to obtain bricks with rhombic pyramids and pyramidal recesses on the body.

Description

Pyramidal brick (patent No. UA 83588 U) can be produced at any brick factory by all known methods. For this, a mold of the original design is used.

The mold consists of a holder 1 (Fig. 1), the lower half-mould 2 (Fig. 2) and the upper half-mould 3 (Fig. 3).

The lower semi-form includes three planes with rhombic recesses for forming rhombic pyramids on the brick body.

Accordingly, the upper sub-mold includes three planes with rhombic pyramids for forming rhombic recesses on the brick body.

OPERATING PRINCIPLE OF THE PRESS FORM:

To form a pyramidal brick through hyperpressing, the method is similar to the Lego brick formation technology (https://youtu.be/A3cXBMW8LMc, https://www.youtube.com/watch?v=qZUzafpNxSM), only the upper and lower half-shapes are moved to clip not vertically, but in the longitudinal axis of the brick at an angle of 45 degrees relative to the horizontal plane.

In the initial position, the lower semi-form (2) is in the holder (1) at a depth that provides the volume of the dry mix required to form brick 4 (Fig. 4).

A bunker with a ready mixture is approaching the formed recessed space, which evenly fills the space, and the bunker is moved to the side.

The upper semi-form (3) is approaching the frame with the holder and at an angle of 45 degrees with respect to the longitudinal axis of the brick body it is lowered onto the lower semi-form (2).

To prevent the mixture from being squeezed out of the formed space, the lower half-mould (2) is deepened to a sufficient depth.

The mixture is pressed and the required shape of the brick is formed.

Upon completion of the formation process, the upper - half-form (3) is removed from the holder, the lower half-form (2) pushes the brick to remove it.

For more efficient pressing, it is necessary to use mechanical vibration. Moreover, the vibration frequency should increase as the mixture is compressed. The vibration frequencies and amplitude must be selected experimentally in the process of developing the technology.

After that, the process continues according to the available technologies.

Also, this method can be applied to the manufacture of pyramidal bricks from foam concrete. To do this, it is enough to fasten the upper and lower half-forms. To supply foam concrete, a technological hole is made in the upper corner of the connection of the three planes of the upper half-form (3).

The figure 5 shows the mold assembly.

The figures show a generalized view of the mold and brick. The number of rhombic pyramids and recesses in the brick body is taken on the basis of technological and aesthetic feasibility.
