Abstract

La présente invention concerne une machine à injecter pour moulage bi-matériau, qui chauffe efficacement les moules de métal, qui évite les interférences entre moules de métal quand les moules sont fermés, et qui empêche efficacement le dépassement de température de cavité. Cette machine à injecter pour moulage bi-matériau comporte deux ensembles d'une première unité d'injection et d'une seconde unité d'injection, respectivement pour le ramollissement et le remplissage au moyen de matériaux à base de résines différentes. Le chauffage des moules de métal commence alors que le plateau matrice rotatif n'a pas encore complètement effectué la rotation de 180°, avant que l'injection ne soit effectuée du côté de la première unité d'injection du côté secondaire, mais après que l'injection ait été effectuée du côté de la seconde unité d'injection du côté primaire. En outre, après le début du chauffage, mais avant l'achèvement de la rotation complète de 180° du plateau matrice, c'est-à-dire avant que les moules ne soient fermés, la température des moules de métal est maintenue dans une plage de températures qui est établie à un niveau supérieur à au niveau de température des moules de métal au début du chauffage, mais inférieur à au niveau de température des moules de métal pendant l'injection.
