A movable platen structure for an injection molding machine in which the platen is in the form of a box-like structure that includes spaced front and rear plates. The platen structure includes a plurality of longitudinally extending beam members that interconnect the front and rear plates and are positioned in parallel relationship and in a generally rectangular array. The rear plate includes on its rear face a plurality of vertically extending pillow block members for pivotally carrying a pivot pin, the pillow block members having inclined sides that intersect with the rear face of the rear plate. Extending across the front face of the rear plate and opposite from the ends of the respective pillow blocks are an upper and a lower transverse beam member, each of which is formed integrally with the rear plate to provide additional structural stiffening and thereby permit the rear plate to be of a thinner and lighter structure.
