摘要：The invention relates to a method for directly producing an investment casting mold by machining a sand mold produced using hardenable bonding agents. In particular, the wear of the tools should be reduced and the dimensional accuracy and precision should be increased during the reproduction of the mold. To this end, a blank mold (1) to be machined is produced while using a variable or fixed casting box (2) having a model assembly (4). Said blank mold comprises specified contours, with regard to volume, of the casting mold and a machining allowance for the milling of the molding material. After filling the casting box (2) with hardenable foundry molding materials, after hardening and after removal from the mold, the blank mold (1) is converted into the casting mold by removing material according to the machining allowance by means of high-speed machining, milling or three-dimensional machining of free-formed planes. The invention relates to investment casting molds for castings made of metal, and to the production of cast part prototypes and individual pieces having small and medium dimensions and masses.
