構成されて成る請求項１記載のプレス金型構造。[Claims for Utility Model Registration] (1) A die punch supported by a die holder fixed to the lower surface of the upper mold, a piercing punch fitted and supported by a retainer fixed to the upper surface of the lower mold, and the above-mentioned upper mold. In a press die structure comprising at least a stripper that presses a plate-shaped workpiece inserted between the lower mold and the die from below toward the die, the stripper extends upward from approximately the center of the die through the upper die. A press mold structure characterized in that an extending scrap passage is formed, and the scrap passage is formed with an irregular cross-sectional shape to prevent the scrap press-fitted from below from falling again to the piercing punch side. (2) The above-mentioned irregular cross-sectional shape has an inlet portion with a diameter slightly larger than the diameter of the piercing punch, a tapered portion that narrows upward from this inlet portion, and an upper end of the tapered portion. 2. The press die structure according to claim 1, wherein the scrap can be press-fitted and is comprised of a narrowest part in the scrap passage and a large diameter part formed above the narrowest part.
