Injection molding apparatus for inserting atypical stiffener

摘要

An injection molding apparatus for inserting atypical stiffener including an upper mold provided with an upper core and an under mold provided with an under core for manufacturing an injection molding product by receiving synthetic resin melt and curing in a state in which an atypical stiffener whose size is not constant is inserted, may include elastic clampers supported by the under mold, embedded in the under core, interlocked with the size of the atypical stiffener, and elastically pressurizing both sides to hold the atypical stiffener to be inserted into a correct position between the upper core and the under core by the atypical stiffener when the synthetic resin melt is introduced.
