A resin injection mold is provided to achieve improved work convenience by assembling a core rod and a cooling pipe in a movable molding unit. A resin injection mold comprises a core rod(21), a rod connector(23), a cooling pipe(25), and a cooling hose(27). The core rod has rod hole(21a) penetrating both ends of the core rod. The core rod has one end fixed in a movable core(6) and connected to a cooling water passage(6a) after passing through the movable template, and the other end disposed in a mold hole(2a) formed at a movable molding unit(2) after passing through a slide block(8). The rod connector has an outer circumferential surface screw-coupled to the slide block, and an inner hole screw-coupled to the other end of the core rod disposed in the mold hole so as to assemble the slide block and the core rod. The cooling pipe has one end with an outer circumferential surface inserted and screw-coupled into the inner hole of the other end of the core rod where the rod connector is assembled, and the other end protruded from the core rod and located in the mold hole. The cooling hose has one end fitted to the cooling pipe in the mold hole.
