射出成形金型。A mold for injection molding a product having a rolled-up portion on one side of the molded product, the mold having a fixed side template with a sprue drilled therein, and a fixed side template that is removably engaged with the fixed side template. ,
and a movable side mold plate in which a runner and a product cavity are formed on a parting surface with the fixed side mold plate, and a movable side mold plate that is formed in a shape corresponding to the winding part of the product cavity and that is inserted through the movable side mold plate and A core knock that forms the product mold surface in cooperation with the mold plate, and a spiral submarine gate that is inserted into the movable mold plate and connects the runner and the cavity via pinpoints on the outer periphery of its tip. a second ejector bin that is inserted through the movable mold plate and whose tip is in contact with the runner; and a base of the core knock and the first and second ejector pins, When the movable mold plate is separated, the core knock is pushed out and the product is pushed up from the movable mold plate, the gate resin is separated between the two pinpoints using force, and then the first and second ejector bins are separated. An ejector mechanism that causes the sprue, runner, and gate resin to protrude and push up from the movable mold plate, and then further pushes up only the second ejector bin to separate the gate resin from the first ejector bin in a series of sequences. An injection mold consisting of.
