Claims

[Scope of utility model registration request]

An outer die that is fixedly attached to the grip die and is divided into two parts, an inner die that is installed inside each of the outer dies so as to be able to move forward and backward in the mold closing direction, and each of the above-mentioned parts is A mold structure for closed forging comprising a forming wedge that engages with a rear portion of an inner die to advance the inner die, and a forming punch fixedly installed on the hedding slider, wherein the forming wedge is provided on the forming wedge. a collar that engages the inner die between before and after completion of molding and forcibly pulls out the inner die from the molded product when the molding wedge returns, and is arranged in parallel at a position that does not interfere with the molding wedge. 1. A mold structure for closed forging, characterized in that it is provided with an auxiliary wedge that is reciprocally movable at the inner die and operates the inner die in a direction to move the molded product away from the outer die.
