INJECTION MOLDING DIE FOR PRODUCING MOLDED PRODUCT HAVING APPEARANCE SURFACE, INJECTION MOLDING METHOD FOR PRODUCING MOLDED PRODUCT HAVING APPEARANCE SURFACE, AND RESIN MOLDED PRODUCT MOLDED BY THE IN,JECTION MOLDING MERHOD. 5 ABSTRACT [PROBLEM] IT IS AN OBJECT TO PROVIDE AN INJECTION MOLDING DIE FOR PRODUCING A MOLDED PRODUCT HAVING AN APPEARANCE SURFACE, AN INJECTION MOLDING METHOD FOR PRODUCING A MOLDED PRODUCT,HAVING AN APPEARANCE SURFACE, AND A RESIN MOLDED PRODUCT MOLDED BY THE INJECTION MOLDING METHOD WHICH IS FREE FROM OCCURRENCE OF 10 APPEARANCE DEFICIENCY SUCH AS A FLOW MARK OR THE LIKE THAT IS A DRAWBACK IN APPEARANCE. [CONSTITUTION] A MOLTEN THERMOPLASTIC RESIN MATERIAL IS INJECTED INTO A CAVITY DEFINED BY A MOLDED PRODUCT'S APPEARANCE SURFACE FORMING PORTION 4A AND A MOLDED PRODUCT'S REAR SURFACE FORMING PORTION 6A THROUGH ONE OR MORE DIRECT GATES 15 AND ONE OR MORE HOT RUNNERS TO FILL THE CAVITY WITH THE MOLTEN RESIN MATERIAL, THEREBY PERFORMING INJECTION MOLDING.
