METHOD OF MANUFACTURING MULTI-COLORED MOLDED PRODUCT, MOLDING DIE AND MULTI-COLORED MOLDED PRODUCT

摘要

PROBLEM TO BE SOLVED: To provide a method of manufacturing a multi-colored molded product, the method which can further enhance design performance.;SOLUTION: The method includes: a slide-die entering step of forming a lower board molding space 81 by making a slide die 70 enter a molding space 80; a lower board molding step of molding a lower board 40 by injecting a melted resin into the lower board molding space 81; a slide-die retreating step of forming an upper board molding space 82 by making the slide die 70 retreat from the molding space 80; and an upper board molding step of molding an upper board 30 by injecting a melted resin different from the lower board 40 in color into the upper board molding space 82. The method is also characterized in that, in the slide-die entering step, a portion of a lower face 71 of the slide die 70 is brought into abutment with a molding face 53 for forming a flat face 30, and an opening 81A is blocked by the slide die 70, thus setting a connecting point between a connecting face 30B and a surface 40A as a boundary between the upper board 30 and the lower board 40.;COPYRIGHT: (C)2013,JPO&INPIT
