A movable platen (22) for an injection molding machine (10) in which the platen (22) is in the form of a box-like structure that includes spaced front and rear plates (70, 72). The platen includes a plurality of longitudinally extending beam members (74) that interconnect the front and rear plates (70, 72) and are positioned in parallel relationship and in a generally rectangular array. The rear plate (72) includes on its rear face (84) a plurality of vertically extending pillow block members (44) pivotally carrying a pivot pin (46), the pillow block members (44) having inclined sides that intersect with the rear face (84) of the rear plate (72). Extending across the front race of the rear plate (72) and opposite from the ends of the respective pillow blocks (44) are an upper and a lower transverse beam member (104), each of which is formed integrally with the rear plate (72) to provide additional structural stiffening and thereby permit the rear plate (72) to be thinner and lighter.
Plateau mobile (22) pour machine de moulage par injection (10) dans laquelle le plateau (22) a une structure en forme de boîte comprenant des plaques avant et arrière espacées (70, 72). Le plateau comprend une pluralité d'éléments de poutres se prolongeant dans l'axe longitudinal (74) qui assurent l'interconnexion entre les plaques avant et arrière (70, 72) et sont positionnés en parallèle et dans une configuration généralement rectangulaire. La plaque arrière (72) comporte sur sa face arrière (84) une pluralité de chaises paliers verticales (44) portant de manière pivotante un tourillon (46), les chaises paliers (44) ayant des parois inclinées qui rencontrent la face arrière (84) de la plaque arrière (72). Se prolongeant à travers la face avant de la plaque arrière (72) et vis-à-vis des extrémités des chaises paliers respectifs (44) se trouvent des poutres transversales supérieure et inférieure (104), chacune étant formée intégralement avec la plaque arrière (72) de manière à procurer un raidissement additionnel de la structure et permettant ainsi d'avoir une plaque arrière (72) plus mince et plus légère.
