Abstract

L'invention concerne un dispositif d'arrêt (9) d'un ensemble noyau de moule (4) d'un outil de moulage (1) comprenant des parties de moule (2, 3). L'ensemble noyau de moule de moule est guidé de manière réglable entre une position de travail et une position d'ouverture. Un premier élément d'arrêt (10) est prévu sur un levier de verrouillage (13) d'un système de leviers (12) qui comprend en outre un levier de commande (14) relié au levier de verrouillage (13). Le système de leviers est supporté sur l'une des parties de moule de manière à pouvoir pivoter autour d'un axe de pivotement (15). Un système de commande (16) fait pivoter le levier de commande et le levier de verrouillage relié à celui-ci lorsque l'ensemble noyau de moule atteint une position intermédiaire, passant d'une position de libération dans une position d'arrêt. Lorsque l'ensemble noyau de moule atteint la position d'ouverture, le premier élément d'arrêt s'ajuste sur un second élément d'arrêt prévu sur l'ensemble noyau de moule.
