PROBLEM TO BE SOLVED: To provide an injection molding device capable, while attempting unprecedented miniaturization, of assuredly releasing a molding from molds.SOLUTION: An injection molding device 10 of the present invention comprises: a fixed mold 11; a mobile mold 12; an injection unit 20 for injecting and feeding, on a mold fastening occasion, a molten resin in-between the fixed mold 11 and mobile mold 12; and an extrusion mechanism 40 for extruding, along the mold releasing direction, a molding molded as a result of the solidification of the molten resin injected and fed by the injection unit 20. The fixed mold 11 and mobile mold 12 are respectively a core and a cavity. The extrusion mechanism 40 is configured on the side of the core. The extrusion mechanism 40 possesses a plurality of elastic support units 42 elastically supported on the fixed mold 11. The elastic support units 42 can be mobilized, when pressed into the cavity on the mold fastening occasion, to a position where the core-side edge surface of the molding can be molded. |
