1. Upper mold
The upper die is the upper half of the entire set of stamping dies, which is the part of the stamping die installed on the sliding block of the press.
2. Upper mold seat
The upper mold seat is the top plate shaped part of the upper mold, which is tightly attached to the press slide during operation and fixed directly to the press slide through the mold handle or directly.
3. Blade wall
The edge wall is the side wall of the cutting edge of the punching die hole.
4. Blade slope
The slope of the cutting edge is the slope on each side of the cutting edge of the punching die hole.
5. Guide sleeve
The guide sleeve is a tubular component that provides precise guidance for the relative movement of the upper and lower mold seats. It is mostly fixed inside the upper mold seat and used in conjunction with the guide pillar fixed on the lower mold seat.
6. Guide pillar
A guide pillar is a cylindrical component that provides precise guidance for the relative movement of the upper and lower mold seats. It is mostly fixed on the lower mold seat and used in conjunction with the guide sleeve fixed on the upper mold seat.
7. Pressure plate (circle)
A pressure plate (ring) is a component used in a stamping die to press and control the flow of stamping materials or process parts. In a deep drawing die, the pressure plate is mostly referred to as a pressure ring.
8. Pressure reinforcement
Pressure bars are rib like protrusions used to control material flow in drawing dies or deep drawing dies. Pressure bars can be local structures of concave dies or pressure rings, or individual parts embedded in concave dies or pressure rings.
