Experience sharing of stamping parts manufacturers: how to define stamping parts die structure. The structural form of the die must be comprehensively considered according to the shape accuracy of stamping. On the premise of satisfying the quality of stamping parts, many problems must be solved to minimize the production cost of stamping parts and determine the structural form of the die.

As we all know: the classification of mold types, simple mold, compound mold, progressive mold, etc., the classification and determination of operation mode. Manual operation, automatic operation, semi-automatic operation, etc., the determination of feeding and discharging methods, the determination of pressing and discharging methods, should choose the precision and mode reasonably.

Designers of stamping parts manufacturers should also consider the maintenance performance, operation and safety performance of the die when designing blanking dies. For example, there are many working parts of the die, and the service life of the die is also very different. We should make those easy-to-wear and easy-to-wear working parts into quick-change structures, and try our best to adjust and compensate the sizes of those easy-to-wear parts separately. The structure of the mold should ensure that the operator's hand does not have to enter the dangerous area, and also ensure the structural size of each moving part so as not to crush the operator's hand within its range of motion.

Because of the choice of compound die, the structure of compound die can be divided into two types: forward and reverse. The following questions need to be considered in the selection of compound die mechanism:

In order to facilitate the operation, if it is required that the punching waste does not appear in the working area of the die, then the flip-chip composite die structure can be adopted, in order to facilitate the punching waste to leak downward through the convex-concave die hole. Based on the strength of the punch, if the wall thickness of the punch is small, the forward structure should be adopted. If the external dimension of the female die is too large, the upside-down structure will be adopted first when the upper die can accommodate the lower die, and if the upper die cannot accommodate the female die, then the upright structure can be considered. If the parts have higher requirements for flatness, better results will be obtained by adopting the formal structure. However, when the elastic pushing device is adopted, the compound die structure of the assembly should be considered first.

Considering the above structure, in order to facilitate operation and improve production, the design of stamping parts manufacturers adopts flip-chip compound die structure. It is preliminarily selected that the parts are pushed out by a rigid pushing device, the rubber is used for unloading, and the middle guide post mould base is used.
