Claims

[Scope of utility model registration request]

It comprises a fixed die 2, a movable die 5, a core 8 attached to both dies so as to be movable forward and backward on the movable die holder 4 by a pull-out mechanism 9, and a product extrusion mechanism 18. The slide core 11 is clamped by the inclined dowel pin 3 of the fixed die holder 1, and is installed so that it can move forward and backward when the mold is opened, and its tip can be butted against the movable die. The overflow recess 13 is provided in communication with the tip of the part of the cavity where water circulation is poor, and the product extrusion mechanism has a built-in cylinder 22 and a pullback rod 24 so that the product 6 can be extruded in two stages. A core drawing and product extrusion device characterized in that a pin plate 21 is movably provided when used in combination.
