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.
