Claims

[Scope of utility model registration request]

A fixed mold in which a concave portion capable of forming the outer periphery of a product to be cast is formed, a first movable mold provided in the fixed mold so as to be able to close and open the mold, and this first movable mold. A second movable mold is provided that allows the mold to be clamped and opened, and the tip fixed to the second movable mold passes through the pin insertion hole of the first movable mold to the fixed part. A tapered pin having a small diameter tip that enters into the recess of the mold, and a product to be cast that is attached to the first movable mold so as to be slidable in a direction perpendicular to the mold opening direction of the first movable mold. a first sliding core forming a part of the inner wall of the mold; and a first sliding core fixed to the fixed mold that can be slid inward of the cast product when the mold is opened. a second slide hanger that forms a part of the inner wall of the product to be cast and is attached to the first movable mold so as to be slidable in a direction perpendicular to the mold opening direction of the movable mold; The second slide core is always biased to a predetermined position, and when the mold is opened, the second movable mold is first moved into the mold. After moving the first movable mold in the opening direction and extracting the taper pin from the recess of the fixed mold, the first movable mold is moved in the mold opening direction and the cast product is extracted from the recess of the fixed mold. After sliding the slide core inward to remove the product and the first slide core, slide the second lower slide core inward to bring the product into contact with the i-th slide core. A die-casting mold for manufacturing a product having an undercut on an inner wall surface, characterized in that the product and the second slide core can be automatically removed from the mold.
