The utility model discloses a punch press sliding block relates to punch press spare part field, and its technical scheme main points are: including main part, the buffer cavity is seted up in main part, is equipped with a plurality of buffer sheets in buffer cavity, and buffer sheet can move in vertical direction relative to main part. In the utility model, when the falling of main part slows down, the buffer sheet exerts a downward force on the main part under the action of inertia, reduces the rebound tendency of the main part and ensures the impact force of stamping, ensures the smooth stamping process, and the elastic sheet and the elastic gasket are all made of rubber material, which reduces the noise generated by the collision between the buffer sheets and the inner wall of the buffer cavity.

This utility model discloses a hot-cutting and punching mold for plastic parts, comprising an upper mold and a lower mold that slide together in an upper and lower manner; the upper mold has multiple punches and a punch heating device for heating each punch; the lower mold is located below the upper mold and is provided with a punching die, which has punching holes that movably engage with each punch. This utility model's hot-cutting and punching mold for plastic parts is used for punching holes in plastic parts and can prevent burrs from forming in the through holes of the plastic parts.
