1. Concept: under the action of external force, the die pin can make the blank into a tool with a specific shape and size. It is widely used in blanking, forming stamping, die forging, cold heading, extrusion, powder metallurgy parts pressing, pressure casting, as well as engineering plastics, rubber, ceramics and other products of compression molding or injection molding. The die has a specific contour or inner cavity shape, and the blank can be separated (punched) according to the contour shape by using the contour shape with cutting edge. The corresponding solid shape can be obtained by using the inner cavity shape. The die generally includes two parts: moving die and fixed die (or punch and die). The blank is put in or taken out when it is separated, and the blank is separated or formed when it is closed. Mold is a precision tool with complex shape, which bears the expanding force of blank. It has high requirements for structural strength, stiffness, surface hardness, surface roughness and machining accuracy. The development level of mold production is one of the important symbols of the level of mechanical manufacturing.

2. Types: there are many kinds of die inserts. According to the processing drawing size and processing technology, they can be divided into: standard punch, referred to as t punch, type a punch, also referred to as secondary punch, guide punch, referred to as guide pin, tooth extraction punch, sub punch, forming punch. Forming punch includes: hexagonal punch, elliptical punch, quadrangular punch, trimming punch, triangular punch and various complex special-shaped punches And so on. Including stamping die (such as blanking die, bending die, drawing die, flanging die, shrinkage die, lifting die, bulging die, shaping die, etc.), forging die (such as die forging die, upsetting die, etc.) are inseparable from the use of punch.
