Abstract

A method for producing a casting mold from a composite mold material for foundry purposes that is composed of different kinds of mold materials that are heat-resistant for the casting of metals and that differ in substantive composition or have different contents of organic or inorganic binders. A solid mold body is prepared from a foundry mold material A that is completely or partially encased during its preparation with a free-flowing chemically bonded foundry mold material B. A composite mold material block is formed after the hardening of the foundry mold material B, which is then machined by a cutting method such as milling, boring, turning, or grinding. The mold cavity is introduced into the mold body consisting of the foundry mold material A, and the inflow system and the feed system are introduced into the mold material block consisting of the foundry mold material B, using CAD data.
