INJECTION MOLD MASTER UNIT DIE BACK PLATE COOLING WITH METAL BACKFILLED PLASTIC MOLD

Abstract:

A reusable mold for injection molding and molding method includes a reusable mold member, a mold cavity defined in the mold member, and at least one heat sink recess defined in the mold member for accommodating a heat sink material. The mold member is mounted on a liquid cooled mold platen. Heat is rapidly removed from the mold cavity when the mold member is used to injection mold a molded part through the heat sink material and through an interface between the heat sink material and the liquid-cooled mold platen. The reusable mold injection molds a molded part and rapidly removes heat from the mold cavity via the heat sink material accommodated in the at least one heat sink recess and through the liquid-cooled platen.
