device Method for producing resin molded article by injection molding, and injection molding device By www.freepatentsonline.com Published On :: Tue, 12 May 2015 08:00:00 EDT 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, the accuracy of the position of a terminal is improved by allowing a core-back mold to move after a terminal, which is an insert component, has been inserted in a terminal tip holding section of a slide mold. By allowing the core-back mold to move by only a prescribed amount prior to injection molding, a resin wall is formed between the core-back mold and the terminal. The inappropriate exposure and shorting of and the adhesion of foreign substances to, and the like, the terminal can thus be prevented. Full Article
