ンチ構造。[Claims for Utility Model Registration] (1) A punch structure of a molding device having a mold for molding a resin material and a punch integrally provided with the mold to form a hole in a molded product. A punch structure for a forming apparatus, wherein the punch has a cooling passage through which a coolant passes. (2) a through hole provided with a refrigerant passage for passing the refrigerant in the mold, and drilled along the diameter direction of the punch so that the cooling passage communicates with the refrigerant passage; A dead-end hole bored along the axial direction of the punch so as to communicate with the through-hole and reach near the cutting edge of the punch, and both openings of the through-hole opening into the dead-end hole are blocked off. A punch structure for a forming apparatus according to claim 1, characterized in that the punch structure comprises a guide plate disposed in the dead-end hole.
