MOLD FOR IN-MOLD COATING MOLDING AND IN-MOLD COATING MOLDING METHOD

摘要

PROBLEM TO BE SOLVED: To provide an in-mold coating molding means constituted so as to enable multi-impression molding, capable of injecting coating in a cavity through a runner even if a cavity has a rising surface part and capable of coating a resin molded product with a coating film having a uniform thickness. SOLUTION: A mold 10 comprises the fixed mold part 3 and the movable mold part 4. A plurality of cavities 5 and 6 being the molding spaces of the resin molded product 14, runners 7 and 8 for injecting a molten resin in a plurality of the cavities 5 and 6 and a coating material injection passage for injecting a coating into a plurality of the cavities 5 and 6 are formed to the mold 10 by the fixed mold part 3 and the movable mold part 4. The mold 10 is characterized in that the runners 7 and 8 are respectively connected to a plurality of the cavities 5 and 6 and a recessed part 17 is formed to the surface excepting the coating material flowing surface of the surfaces forming the runners 7 and 8.
