The present invention refers to an interchangeable system for support and actuation of rotary injection molds, used for the manufacture of plastic multi- component parts. This system is easily installed on conventional injection molding machines. The support system (13) is constituted by a main body that includes a sliding device and a rotary mechanism. The longitudinal sliding device is driven by cylinders (8 and 23) and is supported by the arms of the support (9,15). A rotary unit, including motorization (20) is coupled to the sliding device with two rotary support platens, upper (7) and lower (17). The central mold (4) is supported between the rotary support platens (7 and 17). The frontal mold (12) is fixed on the interior part of the support which is in- turn fixed to the machine platen. The rear mold (2) is fixed to the moving platen of the injection machine (1) as usual. The invention permits not only a rapid mold mutation but also an easy reinstallation on different injection machines.
La présente invention concerne un système interchangeable pour soutenir et actionner des moules d'injection rotatifs, utilisé pour la fabrication de pièces multi-composants en plastique.Ce système est aisément installé sur des machines de moulage d'injection conventionnelles. Le système de soutien (13) est constitué par un corps principal qui comprend un dispositif de coulissement et un mécanisme rotatif. Le dispositif de coulissement longitudinal est dirigé par les cylindres (8, 23) et il est soutenu par les bras du support (9, 15). Une unité rotative, comprenant une motorisation (20), est couplée au dispositif de coulissement avec deux plaques de support rotatives, supérieure (7) et inférieure (17).Le moule central (4) est soutenu entre les plaques de support rotatives (7, 17). Le moule frontal (12) est fixé sur la partie intérieure du soutien qui est ensuite fixée à la plaque de la machine. Le moule arrière (2) est fixé sur la plaque mobile de la machine d'injection (1) comme d'habitude. L'invention permet non seulement une mutation rapide des moules, mais aussi une réinstallation aisée sur différentes machines d'injection.
