Crack gap mold for producing a particle foam part together with an apparatus for producing a particle foam part
20200316829 · 2020-10-08 ·

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.

MOLD ASSEMBLY

An assembly includes a first mold component defining a first portion of a mold cavity and a first slot. The first slot corresponds to a first portion of a retention channel. The assembly also includes a second mold component defining a second portion of the mold cavity and a second slot. The second slot corresponds to a second portion of the retention channel. The assembly also includes a connector having a cross-sectional shape corresponding to a cross-sectional shape of the retention channel. The connector has thermal expansion characteristics that are different from thermal expansion characteristics of the first and second mold components such that when the first and second mold components are in contact and the connector is inserted into the retention channel, heating the assembly causes differential thermal expansion of the connector and the mold components resulting in a clamping force between the mold components.
