Claims

[Scope of Claim for Utility Model Registration] A fixed side mold having a cavity in a fixed side core part and a fixed side plate part, a movable side mold having a cavity in a movable side core part and a movable side plate part, and an ejector. In an injection mold comprising a plate portion and a plurality of movable elements, the stationary side mold includes a stationary side core having a cavity, and a stationary side plate disposed outside the periphery of the core. The side plate has a concave runner, and the stationary side plate part is provided with a concave part, and the concave part is movable by spring force or fluid pressure in the opening/closing direction of the mold, and the stationary side cavity is movable in the concave part. A movable element of a stationary side mold having a part of the movable element and a stopper for controlling the movement of the movable element of the stationary side mold are arranged, and the movable side mold has a movable element having a cavity. A side core, and a movable plate disposed outside the periphery of the core, the movable plate having a part of a concave runner, and the movable plate portion having:
a through hole through which a rod fixed to the ejector plate and connected to a movable element of the movable mold and a rod connected to a part of the runner can move;
A mold for injection molding, characterized in that a recess is provided, and a movable element of a movable mold that can be moved by the rod in the opening and closing direction of the mold and has a cavity is disposed in the recess.
