摘要

PROBLEM TO BE SOLVED: To provide an injection molding machine that can suppress the variation of the amount of molding material filled into a plurality of cavities.SOLUTION: Check valves 170 allowing the flow of a molding material from a branch portion 141 side to a cavity 321 side and preventing the flow of the molding material from the cavity 321 side to the branch portion 141 side are disposed in passages each extending from a branch portion 141 to each cavity 321, and each of the check valves 170 is provided with an escape passage allowing the escape of a part of the molding material to the branch portion 141 side when the pressure due to the molding material from the cavity 321 side to the branch portion 141 side.
