The invention concerns a process for producing a mold, wherein a hollow space is formed within a rigid mold frame (2) which corresponds to the shape of the component to be produced. According to the invention one fills the mold frame, with the exception of an area which surrounds and is in close proximity to the hollow space, with a plurality of filler elements (6), which are formed into at least an essentially incompressible shape. Subsequently, a model (8) of the component to be produced is introduced into the mold and the interstitial space between the model and the filler elements is filled with a masking material or mold shell forming material (4).
Process for producing a mold, in which a hollow space is formed within a rigid mold frame, which hollow space corresponds to the shape of a component to be produced, thereby characterized, that the rigid mold frame (2) is filled with the exception of an area, which is in close proximity to and surrounds the hollow space, with a plurality of filler elements (6), which are joined into a substantially incompressible shape, a model (8) of the component to be produced is introduced into the mold, and the interstitial space between the model and the filler elements is filled with a mask material (4).
Process according to one of the preceding claims, for producing a mold for the production of precision cast models.
