In contrast to the known methods of pressing glasses, for example, chemical laboratory, in the following way: the method of the same designation is used to form the glass from top to bottom - from the bottom of the cup to the bottom.

From the previously known molds for forming cups, made in the form of a subtle, example of detachable, matrix in the shape of the product and a fixed punch, the proposed mold is characterized in that the matrix is provided with a movable, for example spring-loaded, bottom, which is lowered under the action of the punch. The punch and die in the proposed mold are rotating relative to each other.

FIG. 1, 2 and 3 depict sequential molding patterns of a glass.

The proposed mold is a split matrix 1 provided with a movable spring-loaded bottom 2.

The matrix / is strengthened on the press table. Bottom 2 Matrix Creits

the lower end in the guide bearings below the table and the spring 5 is fed to the upper part of the die (Fig. 1). On top of the matrix is a removable ring o. Punch 4 CREIITS in the movable upper part of the iress.

After a portion of the glass from the feeder or other detector arrives in the mold, with the overlapped ring 3, the punch 4 is lowered and presses on the glass, which will fill the free space 6 (Fig. 1), the shape of the expanded upper part of the glass. Upon filling this upper part, the movable bottom 2 together with the glass will go down (Fig. 2).

In the gap between Iuanson 4 and the body of the matrix /, equal to the thickness of the wall of the glass, glass, the shape of the wall of the glass, enters during the whole downward movement.

When the glass formation is completed, the punch 4 rises up and out of the mold. The ring 3 is removed, and the movable bottom 2 under the action of the spring 2828

The cup is made from the mold, becoming its starting position for the second pressing cycle (Fig. 3).

To destroy the 1; 1 "forged surface of the product, rotation of the punch 4 and the movable bottom 2 in one direction and the die / with ring 3 in the other direction is provided.
