The device for the closure of dies is provided with a system of levers (10), (11), (17) and (18) forming a double toggle joint each with seven pivot points and a mobile intermediate plate (14). The device permits a substantial increase in the course of the mobile plate while maintaining unchanged the connections of the connecting rods and permits achievement of a greater length of the useful course of the mobile plate while maintaining parity with the prior art in the space occupied by the course, also a reduction of the thrust forces to which the components of the device are subjected as well as a lower production cost under equal production conditions.
Le dispositif pour la fermeture des moules comporte un système de leviers (10), (11), (17) et (18) formant un joint à rotule double, chacun ayant sept points de pivotement et une plaque mobile intermédiaire (14). Le dispositif permet d'augmenter de façon substantielle la course de la plaque mobile tout en gardant inchangés les raccords des tiges de raccordement et permet d'obtenir une plus grande longueur de la course utile de la plaque mobile tout en maintenant la parité avec les techniques existantes pour ce qui est de l'espace occupé par la course, également une réduction des forces de poussée auxquelles sont soumises les composantes du dispositif, de même qu'un plus faible coût de production dans des conditions de production égales.
