とを特徴とする射出成形用金型。 A movable mold plate that forms a cavity for injection molding when in contact with the fixed mold plate is provided so as to be movable away from the fixed mold plate, and a gate portion that protrudes from the movable mold plate by the biasing force of a spring after injection molding. A cutter for cutting is provided on the side of the movable template, and a magnet is provided on the cutter and the fixed template so as to repel magnetic forces from each other, and when the movable template is in contact with the fixed template, the cutter is moved. A mold for injection molding, characterized in that the mold is configured to be retracted into a movable mold plate by the repulsive force of a magnet against the biasing force of a spring.
