Abstract
The invention concerns an isostatic press mold for producing moldings from powdery ceramic material. The mold comprises two mold parts which are movable relative to one another between a mold-closed position and a mold-open position and which, in the mold-closed position, define between them a mold cavity. On at least one of the mold parts, there is a press diaphragm which on one side defines part of the limiting surface of the mold cavity and on the other side is subjected to a pressure fluid. On its said other side, that is to say on its side facing away from the mold cavity, the press diaphragm is designed with a plurality of recess spaces so that the press mold can be deformed, while at the same time reducing the internal stresses occurring in it.
