る、射出成形金型のゲート除去装置。[Scope of claim for utility model registration] When opening the mold after injection molding, the movable side mold plate 1
an ejector plate 6 that is moved forward from its rear side toward the front side; and an ejector plate 6 that is attached to the ejector plate and inserted into the movable side mold plate and the gate block 3 fixed to the front side thereof so as to be movable forward and backward. A sprue lock pin 7 is provided, and when the mold is opened, the sprue-equipped gate 4 separated from the product 5 in the mold is moved by the advancing movement of the sprue lock pin based on the forward movement of the ejector plate. In the gate removing device for an injection molding mold that removes the sprue lock pin from the gate block, the sprue lock pin is removed from the sleeve pin 7a.
and an inner pin 7b which is fitted into the inner side of the inner pin so as to be movable forward and backward, and one of the inner pin and the sleeve pin 7a is fixed to the ejector plate, and the other one of them 7b is fixed to the ejector plate. , a swinging member 1 whose central portion is pivotally supported by the ejector plate.
5, a fitting portion 7c for holding the sprued gate is provided at the tip of at least one of the inner pin and the sleeve pin, and the ejector plate is attached to the movable side mold plate. During the forward movement of the swinging member, the other arm 15b of the swinging member
A gate removing device for an injection mold, characterized in that a driving member 17 is provided in contact with the gate.
