Abstract
A press for molding plastic materials wherein a stationary head and a movable head, arranged for receiving the two parts of a mold, are mounted on a base in which is installed a horizontal longitudinal member having pivoted at its ends vertical rocker levers. The upper ends of the rocker levers are connected to the stationary head and to the movable head respectively, and the lower ends thereof are connected to the ends of a hydraulic piston-cylinder assembly, which, thereby, applies to the heads a clamping force adequate to join the parts of the mold during the molding operation, without loading the base of the machine.
