ズル樹脂洩れ防止構造。 A double-sided injection molding method in which a manifold occupying an appropriate capacity is positioned on the axis of symmetry of a mold device for double-sided injection molding, and a pair of movable side and fixed side cavity plates are arranged and clamped to each manifold. In order to inject and fill the cavity plate with molten resin from the injection cylinder of the molding machine into the center of one side of the mold device, a tubular core is slid inside the outer cylinder into which a cylindrical heater is fitted on the outside. A structure for preventing resin leakage of an extension nozzle in a mold device for double-sided injection molding, characterized by a freely fitting extension nozzle that is fitted through the extension nozzle.
