发明名称 MOLD SET FOR MOLDING TRIGGER DISPENSER AND INJECTION MOLDING METHOD OF TRIGGER DISPENSER
摘要 PROBLEM TO BE SOLVED: To provide a mold set for molding a trigger dispenser constituted so as to effectively prevent the occurrence of the surface damage of molds moved while mutually slid at the time of mold release after the injection of a resin to prevent the leakage of the resin to the front of the cylinder of the trigger dispenser, having an excellent light operation feeling and excellent in productivity such as the enhancement of a molding yield, the simplification of quality control or the like. SOLUTION: The mold set 30 for molding the trigger dispenser has an almost colunnar mold 32 for a cylinder advancing and retreating with respect to a mold frame 31 so as to form the inner surface of a cylinder part 3, a mold 33 for a supply hole 3a vertically advancing and retreating with respect to the moving direction of the mold 32 for the cylinder and penetrating the cylinder part 3 with its pin-shaped in contact with the side surface of the mold 32 for the cylinder leading end part, and the hard plating layer applied and formed at least to the contact surface of the mold 32 for the cylinder with which the leading end of the mold 33 for the supply hole is brought into contact and having hardness higher than that of the leading end of the mold 33 for the supply hole.
