Title:
METHOD FOR PRODUCING RESIN MOLDED ARTICLE BY INJECTION MOLDING, AND INJECTION MOLDING DEVICE
Document Type and Number:
WIPO Patent Application WO/2011/155493
Kind Code:
A1
Abstract:
Provided is a technology with which, when producing a resin molded article, the inside of which is provided with an insert component such as a terminal fitting, it is possible to prevent the insert component from being exposed at an inappropriate position, and to ensure the desired positional accuracy. In an injection molding device (100), the accuracy of the position of a terminal (90) is improved by allowing a mold core back (50) to move after a terminal (90), which is an insert component, has been inserted in a terminal tip holding section (41) of a mold slide (40). By allowing the mold core back (50) to move by only a prescribed amount (D) prior to injection molding, a resin wall is formed between the mold core back (50) and the terminal (90). The inappropriate exposure and shorting of and the adhesion of foreign substances to, and the like, the terminal (90) can thus be prevented.
