The classification of stamping toolings, generally we can simply divide it into two types, namely engineering dies and continuous dies;
In Raisingelec ,engineering molds can be divided into composite molds, drawing molds, riveting molds, etc. The structure and function of these metal molds are briefly introduced below;
Engineering die: Also known as “single-process die”, it refers to a die that can only complete one stamping process in one stroke of stamping. After this project is finished, the product needs to be taken out of the mold manually or by a manipulator, and then placed in the mold of the next station to continue production until the last process of the mold is completed, and the entire product is not completed. This kind of mold is easy to maintain, but it is time-consuming and labor-intensive to produce, requires more labor and time costs, and has a high product scrap rate.
Composite mold: Common composite mold structures include composite blanking, composite stretching, etc. This mold structure is slightly different from other engineering mold structures. The punch is designed in the lower die, and the other templates are the lower clamp plate , the lower stop plate and the lower stripper plate , and the upper die in turn. It is composed of a master mold , an inner stripping plate and an upper backing plate. The inner stripping is hung on the upper backing plate by a contour sleeve, and then it is supported by a rod or a spring. For example, for the composite mold used for blanking, the internal release is generally 0.50mm from the master mold, and it cannot be lower than the master mold, otherwise the knife edge of the master mold will easily collapse or not fall off. The internal force must be large enough to push the product out of the master mold. Generally, if the material is thicker, we install a nitrogen gas spring on it.
Continuous die: Also known as “progressive die”, it refers to a die that simultaneously completes two or more stamping processes at different stations during one stroke of stamping. This kind of die is difficult to maintain and requires experience. A wealth of fitter masters operate, but the production efficiency is very high. If the speed is fast, thousands of products can be produced in one hour, which saves labor and time costs, and the product scrap rate is low.
