Abstract

L'invention concerne un dispositif (1) pour outils de moulage pour moulage par injection à canaux chauffants (2) de matière plastique et qui comprend des stock-moules mobiles guidés par des guides (5). Les guides (5) sont disposés dans des évidements fraisés (7) dans le coin respectif (6) du moule de forme carrée. Les évidements de réception fraisés de forme carrée (7) des guides sont orientées dans une direction commune (8) vers le centre (9) de l'outil de moulage, l'allongement thermique de l'outil étant agencé de manière à s'étendre dans la direction (8) du centre (9) de l'outil de moulage. En outre, les guides (5), qui s'étendent dans les deux stock-moules de l'outil de moulage, sont formés d'un bouchon présentant une tête de forme carrée, qui est guidée par l'évidement de réception fraisé de forme carrée (7).
