Abstract
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, including forming a hollow space within a rigid mold frame, which hollow space corresponds to the shape of a component to be produced, said process comprising
- filling the rigid mold frame (2) with the exception of an area, which is in close proximity to and surrounds the hollow space, with multiple identically shaped building blocks (6), which are joined into a substantially incompressible shape,
- introducing a model (8) of the component to be produced into the area, and
- filling the area between the model and the building blocks with a mask material (4).
