PURPOSE: To perform insert-molding on plural members through respectively separate runners by respectively arranging plural molds at a prescribed angle on a concentric circle with a rotary shaft as the center, and successively transferring the cavity side at a prescribed angle to the core side. CONSTITUTION: A cavity 1 is brought into close contact with the core 2 side, and a part continuing with the cavity is molded in its mold through a runner 1a of a first mold 1X. Next, the cavity 1 side retreats, and can rotate by separating from the core 2 side, and a hydraulic device 8a is actuated, and the cavity 1 is rotated by a prescribed angle, that is, 120 deg. through an actuating shaft 9, an engaging claw 7 and a rotary shaft 3, and this cavity 1 side is again returned to the core 1 side, but a second mold 1Y formed in the cavity 1 is opposed in this position, and insert-molding is performed on a part continuing with the cavity through a runner 1b of the mold 1Y. Similar operation is repeated hereafter, and a third mold 1Z of the cavity 1 is opposed according to rotation of the cavity 1, and insert-molding is performed on a part continuing with the cavity through a runner 1c of the mold 1Z. |
