Abstract

Les machines à mouler par injection de type connu présentent des systèmes de verrouillage compliqués à deux paires de griffes nécessitant une mise en oeuvre importante de moyens pour la préparation. L'invention a en conséquence pour objet un dispositif de verrouillage dans lequel la première surface de transmission de force (20) est formée, de façon connue, entre une griffe de la colonne de fermeture (7) et un espace libre (18) de la boîte de verrouillage (14), et la deuxième surface de transmission de force (15), entre un épaulement du diamètre extérieur de la boîte de verrouillage (14) et un épaulement du diamètre intérieur du piston de fermeture (12).
