Zusammenfassung:	The utility model relates to a mould, in particular to a punching mould. The punching mould comprises a concave mould and a protruding mould. The concave mould is provided with a round hole. The punching mould is characterized in that the round hole is a cone-shaped hole and a plurality of line cutting lines are arranged on the inner wall of the cone-shaped hole. As the cone-shaped hole is adopted and the line cutting lines are arranged on the inner wall of the hole, waste materials with clamping points can be clamped into the concave mould, the protruding mould does not bring out the waste materials during returning, defective products are avoided, and production efficiency is not influenced.
