Casting mold for the production of a casting having a front and a back from a hardenable casting compound

Abstract

A casting mold for producing a casting having a front side and a rear side from a curable casting compound, including at least a first mold part shaping the front side and a second mold part shaping the rear side, the mold parts together delimiting a casting cavity. The first mold part has a first metal layer delimiting the casting cavity and the second mold part has a second metal layer delimiting the casting cavity. At least one metal layer is at least partially deformable for the purpose of changing the casting cavity volume. At least one mold part has an areal intermediate layer which is composed of an elastically deformable and compressible material and against which the metal layer of the mold part is movable with build-up of a restoring force on the part of the deforming intermediate layer.
