置。 In a reaction injection molding device that molds a product by injecting a reaction-curing resin into the cavity of a mold with a slide core in the core body, a sliding surface formed between the slide core and the core body or the mold. A heat insulating material is provided on the slide core and the core body or the mold facing the surface, and the sliding surface is surrounded by the heat insulating material to maintain the inside of the sliding surface at a temperature lower than the cavity temperature. A sealant discharge port is opened on the sliding surface, and a thermosetting sealant that does not harden within the insulated sliding surface but hardens at the cavity temperature is applied to the sealant discharge port into the cavity of the mold using a reaction-curing resin. 1. A reaction injection molding apparatus characterized in that a sealant supply mechanism is connected to the sealant supply mechanism for discharging the sealant before the injection.
