Abstract

PURPOSE:To perform integral molding simply, by a method wherein a core member is correctly set within upper and lower molds for molding by a positioning device, molten synthetic resin is injected, the positioning device is removed out of the mold, and the resin is filled therein. CONSTITUTION:A core member 3 of metal or the like is supported at its upper and lower sides and correctly positioned within an upper mold 1 and a lower mold 2 of a metal mold for molding by a positioning device 4 using an air cylinder or hydraulic mechanism. Molten synthetic resin is injected through a fluid injection port 5 and the fluid is filled. Pressure in the air cylinder is reduced so that the positioning device is removed out of the mold naturally and the resin is injected in trace of the removed device. Thereby the core is inserted in the synthetic resin member and integral molding is performed.
