Method for producing a cast part, casting mould and cast part produced therewith

Abstract

A method for producing a cast part from metal, a metal alloy or from plastic, with at least one complex internal structure, in particular with at least one hollow space, by at least one casting mold, is disclosed. The method includes the following steps: a) providing at least one core element, wherein the core element peripherally reproduces the complex internal structure and has a metallic layer on its outer periphery; b) forming a first casting mold or negative mold for producing a positive mold reproducing the cast part, with one or more cast-in core elements; c) casting an enclosure around the positive mold to form a second casting mold or negative mold of the cast part and removing the positive mold; d) filling the casting mold or negative mold with casting material and cooling the casting material down; and e) removing the enclosure and removal of the cast part.
