Abstract:
(EN) 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.
(FR) La présente invention concerne un moule pour injection-compression, destiné à la production d'un élément en mousse de particules expansées, ledit outil de moulage comprenant deux demi-moules. Les demi-moules sont montés pivotants l'un relativement à l'autre, de manière à pouvoir être positionnés à une distance variant localement, pendant l'introduction des particules expansées et, sous l'effet du mouvement de pivotement, sont rapprochés à une distance variable lorsqu'ils sont poussés l'un contre l'autre jusqu'à une position de fermeture. De cette manière, il est possible de compresser de manière homogène des zones de la cavité de moulage présentant des épaisseurs différentes, ou de compresser de manière différenciée des zones présentant une même épaisseur.
(DE) Die vorliegende Erfindung betrifft ein Crackspalt-Formwerkzeug zum Herstellen eines Partikelschaumstoffteils mit zwei Formhälften (2, 3). Die Formhälften (2, 3) sind derart zueinander schwenkbar angeordnet, dass sie beim Füllen mit Schaumstoffpartikeln bereichsweise unterschiedlich weit voneinander beabstandet sind und beim Zusammendrücken in eine geschlossene Stellung aufgrund der Schwenkbewegung unterschiedlich weit zusammengefahren werden. Hierdurch lassen sich Bereiche des Formraumes (6) mit unterschiedlicher Dicke gleichmäßig verdichten bzw. mit gleicher Dicke unterschiedlich verdichten.
