SU768639A1 - Press mould for producing intermittent profile articles - Google Patents

Description

one

The invention relates to the molding of intermittent profile products and can be used in the manufacture of diamond and abrasive wheels.

A mold is known that includes 5 die, upper and lower punches, upper and lower guide sleeves.

Closest to the proposed technical essence and the achieved result is a mold for forming articles of a discontinuous profile, including a die, upper and lower punches and inserts 2.

However, in this mold 15, the moldable mass is unevenly distributed over the entire cross section, and therefore the same density is not ensured over the entire cross section of the product, which reduces its quality.

The purpose of the invention is to improve the quality of molded products.

This is achieved by the fact that the known mold for forming articles of a discontinuous profile, including the matrix 25, the upper and lower punches and CLS, is equipped with a platform with rods connected to liners, and the platform is installed with the possibility of reciprocating SO.

The drawing shows the described mold;

The mold consists of a platform 1 with a stem 2, a housing 3 on which the die 4 is installed, a lower punch 5, a sleeve 6 and inserts 7 moving in the grooves of the lower punch 5. and connected with rods 8 to a platform 1 equipped with a drive a spring.

When the flywheel 9 is rotated, the screw 10 is screwed into the bottom 11, and the platform 1 moves down and removes the spring 12. Under the action of its own weight, the rods 8 and liners 7 are lowered. The molding weight is leveled and evenly laid down over the entire cross section of the mold, which ensures It ensures the same density of its installation throughout the entire continuous section of the paper (liners 7 do not prevent this, since they are recessed in the grooves of the lower punch). The rotation of the flywheel 9 turns the screw 10 out of the bottom 11, while the platform 1 under the action of the spring 12 moves upwards and through the rods 8 moves the inserts 7 in the grooves of the lower punch 5 relative to
