MANUFACTURING METHOD FOR SIMULTANEOUSLY INJECTION COMPRESSION MOLDED AND DECORATED ARTICLE AND MOLD FOR SIMULTANEOUSLY INJECTION COMPRESSION-MOLDED AND DECORATED ARTICLE

摘要

PROBLEM TO BE SOLVED: To provide a manufacturing method of a simultaneously injection compression-molded and decorated article and a mold for the simultaneously injection compression-molded and decorated article. SOLUTION: A decorative film 5 is set between an A-mold 1 and a B-mold 2 so that the film 5 is in touch with the mold. After a molding resin is cast from a gate 14 mounted in the central portion of the inner surface of the A-mold into a molding space portion 3 formed by the decorative film and the A-mold, the mold is closed and the molding resin is hardened to produce the simultaneously injection compression-molded and decorated article. The molding space portion comprises a plurality of article molding space portions communicating with each other and an outer frame molding space portion enclosing each article molding space portion. The outer frame molding space portion comprises an auxiliary molding space portion 32 in the vicinity of the gate mounted in the central portion of the inner surface of the A-mold and an additional molding space portion 33 located apart from the gate via the article molding space portion. The molten molding resin is filled in the article molding space portions 31 via the auxiliary molding space portion, and then is filled in the additional molding space portion.
