DOUBLE COMPRESSION MOLDING MACHINE AND MANUFACTURING METHOD OF PRODUCT
20200206986 · 2020-07-02 ·

In a double compression molding machine, a supporting member supports an internal part to be sealed in an inner portion of a product to be molded. A mold includes a cavity in which the product is to be molded, a cylinder hole which communicates with the cavity and into which a plunger is inserted, an insertion hole which communicates with the cavity and into which a supporting member is inserted and a fixing member which fixes the internal part in the cavity. A plunger driving apparatus presses a resin material inserted in the cylinder hole in the cavity such that the product is molded by advancing the plunger from a retracted position toward the cavity. A supporting member driving apparatus presses the supporting member until the supporting member abuts on the internal part fixed in the cavity, and extracts the supporting member from the cavity.
