Abstract

A device has a first mold plate mounted rotatably using a shaft, and a second mold plate, between which a cavity is formed. The device further has an apparatus for applying an erecting force to the first mold plate such that in the open state of the device the first mold plate is inclined to the second mold plate, and an angle of inclination decreases with increasing degree of clamping of the device. The device further contains an axial guide in which the shaft of the first mold plate is mounted rotatably and at the same time displaceably in the direction of the second mold plate.
