PROBLEM TO BE SOLVED: To avoid a bend of a molding and a damage due to a twist or the like by opening a mold after an injection molding, projecting a first extruding member from one mold side into its recess to extrude a molded part, and synchronously projecting a second extruding member into the recess to push out its accessory. SOLUTION: After an original plate 3 is formed, a mold is opened. Then, a molded part of the plate 3 and a runner are lifted by respective eject pins 47, and a curled part is simultaneously lifted by a plunger 34. Since the pins 47 and a locking mechanism 68 are effectively mechanically coupled by an electromagnetic clutch 91 and a coupler 59, the plunger 34, a sliding mechanism 67, the mechanism 68 and the pins 47 are integrated, and simultaneous attitude changes of high accuracy of the pins 47 and the plunger 34 are performed. Thus, a damage such as a twist, a bend or the like is not imposed on the molding at the time of ejecting the molding, but a resin molding of high quality can be obtained. |
