METHOD FOR PRODUCING A CASTING MOULD FOR FILLING WITH MELT AND CASTING MOULD

摘要

Method for producing a casting mould (6), in particular a shell (7), for filling with melt and/or a core for producing a cavity in a cast part, with a wall (8) of a refractory and gas-permeable material, wherein the casting mould (6) is built up by a generative manufacturing process. According to the invention, it is provided that the wall (8) of the casting mould (6) is formed with a supporting structure (9) especially designed for the casting mould and formed by open and/or closed voids and/or that different wall thicknesses are provided, in order to support the casting mould largely independently against the casting pressure in a dimensionally stable manner and also to specifically isolate thermal energy in the melt or dissipate it from the melt.
