Abstract
The invention relates to a crack-split moulding tool for producing a foam particle part, having two mould halves (2, 3). The mould halves (2, 3) are pivotably mounted relative to one another such that they can be arranged at a varying distance from each other in certain sections when being filled with foam particles and when pressing together, are moved together at a varying distance until in a closed position, due to a pivoting movement. As a result, it is possible to homogeneously compress areas of the moulding cavity (6) having a different thickness and to compress in a different manner, area having the same thickness.

Crack gap mold for the production of a particle foam part, the crack gap mold comprising two mold halves which, during filling the mold with foam particles, are arranged in a crack gap position, in which the mold halves are spaced somewhat apart from one another, as compared with a closed position, and which are designed for pressing together the foam particles therein before welding,
- wherein the mold halves are arranged so as to be movable relative to one another in such a way that, on filling with foam particles, certain areas are spaced differently apart so that, during compression into the closed position, the mold halves at least in certain areas are moved a different distance together by mounting one of the two mold halves pivotably around a swivel axis so that, on the compression from the crack gap position into the closed position, this mold half executes a swiveling movement during the compression to produce the particle foam part.
A method for producing a particle foam part, the method comprising:
- providing a crack gap mold comprising two mold halves;
- filling the mold with foam particles while arranging the two mold halves in a crack gap position, in which the mold halves are spaced somewhat apart from one another, as compared with a closed position, and which are designed for pressing together the foam particles therein before welding;
- positioning the mold halves relative to one another in such a way that, on filling with foam particles, certain areas are spaced differently apart;
- and
- compressing the two mold halves into the closed position, while moving the mold halves at least in certain areas a different distance together by mounting one of the two mold halves pivotably around a swivel axis so that, on the compression from the crack gap position into the closed position, this mold half executes a swiveling movement during the compression to produce the particle foam part, which is roughly wedge-shaped.
