Mold comprising outer mold parts and molding material cores inserted into same

摘要

A mold has outer mold parts and inserted molding material cores. Together, the parts and cores form a mold cavity. The inner cores of molding material are arranged in several layers one above the other. The inner cores are clamped in between the outer mold parts and a final covering core of mold material. A continuous clamping force is applied between the parts and cores. The mold cavity is formed by surfaces of the outer mold, surfaces of the inner cores and the covering core.
