金型。 A cavity is provided between the fixed mold and the movable mold, and a gate opening into the cavity and a runner communicating with the gate are provided in either one of the fixed mold and the movable mold, and the gate and the runner are provided with a cavity. In the injection mold in which molten resin is supplied into the cavity through the runner, when the movable mold is joined to the fixed mold by the runner, When the movable mold comes into contact with either one, it is displaced in one direction, narrowing the volume inside the runner, and when the movable mold is separated from the fixed mold, it is displaced in the other direction, expanding the volume inside the runner. An injection mold characterized by having a piston inserted therein to reduce the internal pressure.
