Abstract

PURPOSE:To provide the titled resin mold imparting surface gloss to a plastic molded product by forming a thin film of an acrylic ester resin on the surface of the resin mold for molding a plastic. CONSTITUTION:A release agent coated on a wooden mold 1 having a shape same to the cavity side of a plastic molded product to be assembled into a frame 2 and an epoxy resin 3 compounded with metallic powder is injected singly to be cured under heating. After the resin is cured the wooden mold 1 is removed and, after the resin 3 is finished to a prescribed dimension, an acrylic ester type resin is coated on the surface thereof to form a thin film 2 with a thickness of 100mm. or less and subjected to curing treatment by ultraviolet irradiation to obtain the objective resin mold.
