成樹脂製品の射出成形金型。[Scope of Claim for Utility Model Registration] (1) A model core rod that has been molded and polished into an external shape corresponding to the external shape of the required synthetic resin product, with the attached part facing upward, and an appropriate thickness plated on the surface thereof. A molten lining metal is cast onto the outer peripheral surface of the nickel plating layer and is solidified and molded as an integral part, and the lining metal is freed from trapped air bubbles and shrinkage by the pressure of the presser during the molten state of casting. In injection molds for synthetic resin products in which the nests are crushed and firmly bonded by casting, the metal lining is
An injection mold for synthetic resin products characterized by being composed of zinc or a zinc alloy containing zinc as the main material. (2) The injection mold for a synthetic resin product according to claim 1, wherein zinc obtained by electrorefining is used as the backing metal. (3) The backing metal contains 83% zinc, 10% aluminum, 6.5% copper, and 0.0% magnesium.
An injection mold for a synthetic resin product according to claim 1, in which a zinc alloy containing 5% zinc as a main material is used.
