mold‘s life depend on designing

(1) The accuracy of the guide mechanism of the mold. Accurate and reliable guidance is more effective in reducing the wear of mold working parts and avoiding the great influence of convex and concave mold flaws, especially in the case of gapless and small clearance stamping dies, compound dies and multi-position progressive dies. In order to improve the life of the mold, the design must be based on the nature of the process and the accuracy of the parts, and the correct selection of the guide form and the accuracy of the guide mechanism must be determined. (2) Die (convex, concave die) edge geometry. The shape of the convex and concave molds, the fit clearance, and the radius of the fillet not only have a greater impact on the stamping part, but also have a great influence on the wear and life of the mold. For example, the clearance of the mold directly affects the blanking quality and die life. For higher accuracy requirements, smaller gap values should be selected in the design; otherwise, gaps can be appropriately increased to increase die life.
