A linkage assembly (38) for a multiple level stack mold molding machine (10) having a fixed platen (14), a movable platen (32), a plurality of carriage assemblies (70). The linkage assembly (38) includes an arm (92, 94) on each carriage assembly (70) pivotally connected to a central pivot point on one of the carriage assemblies (70). An arm (86) also extends between the fixed platen (14) and an end of one of the arms (92) on a carriage assembly (70). Another arm (88) extends between the movable platen (32) and an end of another of the arms (94) on another of the carriage assemblies (70). A pair of arms (96, 98) extend between each adjacent carriage assembly (70), each one of the pair of arms (96, 98) extends from an end of an arm (92, 94) of one carriage assembly (70) to a central pivot point on an adjacent carriage assembly (70). Each arm (96, 98) of the pair of arms is shaped to extend around a periphery portion of a mold opening to enable full access to the core (42) and cavity plates (50).

L'invention porte sur un ensemble de tringlerie pour une machine de moulage à moules empilés à de multiples niveaux comprenant un plateau fixe, un plateau mobile et une pluralité d'ensemble chariots. L'ensemble de tringlerie de l'invention comprend, sur chaque ensemble chariot, un bras relié pivotant à un point de pivotement central sur l'un des ensembles chariots. Un bras s'étend également entre le plateau fixe et une extrémité de l'un des bras d'un ensemble chariot. Un autre bras s'étend entre le plateau mobile et une extrémité d'un autre bras d'un autre ensemble chariot.Une paire de bras s'étendent entre chaque ensemble chariot adjacent, chacune des paires de bras s'étendant entre une extrémité d'un bras d'un ensemble chariot et un point de pivotement central d'un ensemble chariot adjacent. Chaque bras de la paire de bras possède une forme telle qu'il s'étend autour d'une partie périphérique d'une ouverture de moule, permettant le plein accès au noyau et aux plaques de matrice.
