MOLD FOR INJECTION MOLDING, AND INJECTION MOLDING METHOD, INJECTION-MOLDED ARTICLE, AND INJECTION MOLDING MACHINE USING THE MOLD FOR INJECTION MOLDING

摘要

PROBLEM TO BE SOLVED: To provide a mold for injection molding, which has a fixed side template and a movable side template, in which a cavity is formed between the fixed side template and the movable side template and the injection molding of an injection-molded article is carried out by filling a molten resin into the cavity, and to provide a technique for removing the injection molded article from the mold for injection molding without trouble even when a pin member which obstructs the smooth releasing of the injection-molded article is present.;SOLUTION: The pin mounting hole 29 for inserting and mounting the pin member 30 having a pin shape is formed on, among the inner wall surfaces of the cavity 8, a second side-wall surface 28b that is an inner wall surface other than the inner wall surfaces perpendicular to the mold removing direction of the injection-molded article 26. On the second side-wall surface 28b, a protruding portion 40 protruding from the second side-wall surface 28b is formed in the surface area 39 on a side opposite to the mold removing direction with respect to the pin mounting hole 29 as a reference.;COPYRIGHT: (C)2012,JPO&INPIT
