Abstract

The invention relates to molds for compressing bulk materials, preferably not prone to pressure adhesion. The purpose of the invention is to expand the technological capabilities of the mold by pressing: A products of various sizes of height. In one of the diametrically located pairs of vertical valleys of the matrix 1 install the rods 8 of the limiter. After being placed on the punch 3 of the matrix 1, bulk material is poured into it and a movable punch 4 is installed with the condition that its horizontal protrusions are located above the rods. The pressing is performed up to the stop of the projections of the punch 4 into the rods. After removal of the press slide up, the die is transferred from the punch 3 to the pressing-out ring. Using the handles 7 located on the die and the die 4, the latter is rotated around its axis relative to the die with the condition of its protrusions between the rods 8, and the product is pressed out. To retrofit the mold to a different size, the rods 8 are moved into the corresponding diametrically located pair of cavities of the die, 4 slugs. cl

Description

FIG. 13

This invention relates to a mold for compressing bulk materials that are preferably not prone to pressure adhesion.

The purpose of the invention is to expand the technological capabilities of the mold by pressing products of various sizes.

Fig. 1 shows a diagram of a mold at the moment of pressing a product; FIG. 2 is a view A of FIG. 1; on fig.Z - diagram of the mold at the time of extrusion of the product; figure 4 - view B in fig.Z.

A mold for pressing bulk materials contains a matrix 1 with diametrically located at its upper end pair of vertical depressions 2 of different depths, a stationary punch 3, a movable punch 4 with two horizontal projections 5 on its non-working part, a pressing ring 6, handles 7, located on the matrix and the non-working part of the movable punch, as well as the limiter in the form of two identical rods 2. The depth of the depressions 2 within each diametrically located pair has the same value.

The mold works as follows.

Before the start of the pressing process, rods 8 of the limiter are installed in one of the diametrically located pairs of vertical valleys 2 of the matrix 1 (in accordance with the specified size of the compression product). After being placed on the immovable punch 3 of the matrix 1, the dose of bulk material is poured into the latter and the movable punch 4 is installed with the condition of its horizontal protrusions 5 above the restraint rods. The bulk material is pressed until the horizontal protrusions of the movable punch rest against the rods of the stopper. After the press slide is retracted upward, the matrix with the extruded product, the movable punch and the stopper stop from the stationary punch to the pressing out ring 6. With the help of the handles 7 located on the matrix and the movable punch, the latter is turned

around its axis relative to the matrix with the condition that its horizontal protrusions are located between the rods 8 of the stopper. The finished product is extruded.

At the end of the extrusion of products of this size, the mold is re-adjusted to another required size, for which the restrictor rods 8 are moved to the corresponding diametrically located pair of vertical cavities 2 of the matrix. At the same time, in order to reduce the time for searching for the necessary pair of vertical cavities (in the process of re-adjusting the mold), each of them is marked, for example, on the outer cylindrical surface of the die, indicating the specific size of the product to be pressed.

The proposed design has advanced technological capabilities due to the compression of products of various sizes of height, due to the possibility of re-adjusting the mold, respectively, to various sizes without the use of additional individual limiters.
