MANUFACTURING PROCESS OF SIMULTANEOUS INJECTION MOLDING AND DECORATION ARTICLE AND MOLD FOR SIMULTANEOUS INJECTION MOLDING AND DECORATION

摘要

PROBLEM TO BE SOLVED: To prevent generation of a weld or the like in a core of the molded product, in a manufacturing process of a simultaneous injection molding and decoration article by injecting a molding resin into a molding space formed between a decoration film and a mold.;SOLUTION: The manufacturing process of the simultaneous injection molding and decoration article is as follows. A first mold 1 is equipped with a gate part 14 to inject the molding resin, the molding comprises a resin injection molding space 32, an article molding space 31 and a resin discharge molding space 33, wherein each boundary between the resin injection molding space 32, the article molding space 31 and the resin discharge molding space 33 is mutually communicating without division. The injected molding resin flows and spreads roughly radial from the gate part 14 and fills the resin injection molding space 32, filling the resin molding space 31 keeping a roughly radial shape, and flows into the resin discharge molding space 33 like being discharged from the article molding space 31, thereby filling the whole molding space.;COPYRIGHT: (C)2005,JPO&NCIPI
