INJECTION COMPRESSION MOLDING METHOD AND INJECTION COMPRESSION MOLDING DEVICE FOR EMBODYING THIS METHOD

摘要

With an object of providing a method for injection compression molding and an apparatus for working the method which can speedily and efficiently carry out multi-cavity molding of high-precision molded products, the method according to the present invention is characterized by carrying out in order a process comprising the steps of providing a mold comprising a movable mold and a stationary mold, and being provided with a plurality of cavities each being provided with a movable core and a hot runner through which a distributed flow of molten resin is supplied to the cavities; closing the mold (2, 3); then supplying the molten resin to fill a plurality of the cavities (1A, 1B) provided in the mold while making the molten resin distributed to flow through the hot runners (10A, 10B) provided for respective cavities; individually detecting a resin-filled state in each cavity; when the resin-filled state in the cavity is detected to become in a specified state, individually closing a gate of the cavity completely; individually advancing a top of the movable core (5A, 5B) into the cavity to individually raise a pressure in the cavity up to a specified value; and ejecting molded products after a specified cooling time. <IMAGE>
