INJECTION FOAM MOLDING MACHINE

摘要

PROBLEM TO BE SOLVED: To provide an injection foam molding machine low in cost by reducing the number of core-back devices and miniaturizing them, and to provide an injection molding machine prevented from reduction of core-back resisting force and reduction of mold opening speed by applying an unloading oil in a hydraulic circuit to a mold opening oil chamber of a clamping cylinder in core-back operation.

SOLUTION: The injection foam molding machine includes a program for core-back use for performing simultaneous operation control using two sets of mold opening/closing actuators and two sets of devices for core-back use in foam core-back operation for separating a movable mold platen 3 from a fixed mold platen 2.
