INJECTION MOLDING MACHINE AND THERMOPLASTIC SYNTHETIC RESIN MOLDED PRODUCT

摘要

PROBLEM TO BE SOLVED: To perform the injection molding of a thin-walled and/or deep container-shaped molded product by a compact injection molding machine. SOLUTION: An injection molding machine 11 is constituted so that a plunger 13 being an extruder is fitted in the accumulator 12 connected to a mold 14 in a freely slidable manner and the shape of the leading end part 22 of the plunger 13 is fitted to the pointed shape of the leading end part 15 of the accumulator 12. By this injection molding machine, a thin-walled and/or deep container-shaped molded product wherein the ratio L/t of the raw material max. flow distance L in the mold 14 to the wall thickness (t) of the molded product becomes 200 or more is molded.
