Method and Device for Batched Compression Molding of Rubber and Plastic Products by Means of Multiple Mold Cavities
20200039123 · 2020-02-06 ·

Provided is a method and device for batched compression molding of rubber and plastic products by means of multiple mold cavities, including alternate operation of a blank shuttle and a male mold that is in a bottle cap mold, being controlled by means of engagement of two incomplete gear sets. Mold opening motion, isostatic pressing energy storage, and spring energy storage are implemented by means of the engagement characteristic of the incomplete gear sets, and mold closing and compression molding are implemented by means of the non-engagement characteristic, isostatic pressing energy storage, and pressurization of the incomplete gear sets. The method and device effectively resolve the general problem of low production efficiency and poor precision and stability of existing compression molding cap manufacturing equipment.

METHOD FOR PRODUCING FIBER-REINFORCED RESIN MOLDED BODY
20180178414 · 2018-06-28 · ·

A method for producing a fiber-reinforced resin molded body, including heating a fiber-reinforced resin molded body precursor containing thermoplastic resin as matrix resin to soften it and molding it in a molding die, where temperature unevenness between the inside and surface of the fiber-reinforced resin molded body precursor can be reduced. The method includes a first step of storing a fiber-reinforced resin molded body precursor containing thermoplastic resin as the matrix resin and containing conductive fibrous materials therein into a heating furnace with heating apparatuses while holding the precursor using a pair of holding tools, which also function as electrodes, and then actuating the heating apparatuses while supplying current to the precursor from the electrodes, thereby softening the precursor; and a second step of transferring the softened precursor to a molding die using the holding tools, and molding a fiber-reinforced resin molded body in the molding die.
