A die clamp for plastic moulding ma- chines, in particular injection moulding ma- chines, has four traction means that connect a fixed die platen (3) to a supporting platen (5) and that absorb reaction forces generated by a die closing mechanism (7) that is arranged on the supporting platen (5) and acts upon a moving die platen (13). The traction means (17, 17', 19, 19', 21) are at least partially C- shaped in order to ensure free access to the space between the die platens. In order to keep the fixed platens (3, 5) interconnected by the traction means in an exactly paral- lel position, all traction means, whether their shape is the same or not, are sized to present exactly the same resistance to deformation in the longitudinal direction of the machine, or the traction means (21) are connected to the fixed platens by resilient force transmission means or deformable elements (35) whose resiliency compensates for the various degrees of resistance to deformation of the traction means (17, 21).

Un mécanisme de serrage de moule pour machines de moulage de matières plastiques, notamment des machines de moulage par injection, comprend quatre organes de traction qui relient un plateau porte-outillage (3) à un plateau de support (5) et qui absorbent les forces de réaction générées sur un plateau porte-outillage mobile (13) par un mécanisme de fermeture (7) monté sur le plateau de support (5). Les organes de traction (17, 17', 19, 19', 21) ont au moins partiellement la forme d'un C afin d'assurer un libre accès à l'espace situé entre les plateaux porte-outillage. Afin d'assurer un parallélisme exact entre les plateaux fixes (3, 5) reliés par les organes de traction, les organes de traction sont tous dimensionnés de façon à présenter exactement la même résistance à la déformation dans le sens longitudinal de la machine, qu'ils aient ou non une forme identique, ou les organes de traction (21) sont reliés aux plateaux fixes par des éléments élastiques de transmission des forces ou par des éléments déformables (35) dont l'élasticité compense les différents degrés de résistance à la déformation des organes de traction (17, 21).
