Claims

[Scope of utility model registration request]

a first mold; a second mold movable in a direction toward and away from the first mold by a predetermined amount;
A third mold is located on the opposite side of the first mold so that a mold exists in the middle, and cooperates with the first and second molds to form a molding cavity when the molds are mated. a mold, an extrusion member provided on the first mold side that performs an extrusion operation after opening the mold, and the second
an elastic member that biases the mold and moves the second mold in a direction away from the first mold when the mold is opened, thereby releasing the molded product from the first mold; a connecting member that connects the second mold so as to transmit the movement of the second mold in the direction of separation from the first mold to the extrusion member;
The movement of the extrusion member in conjunction with the movement of the mold releases the molded product from the first mold in cooperation with the second mold, and the extrusion operation of the extrusion member after opening the mold releases the molded product into the second mold. A two-stage extrusion device for a forming die, which consists of a knock-out member that releases the mold from the mold.
