How to improve the die service life of practical methods?
With the continuous improvement of industrial automation, the application of mold is more and more extensive.However, in many enterprises in China, the service life of molds is still relatively low, which is only equivalent to 1/3-1/5 of that in foreign countries.Working parts of die life is low, poor accuracy stable, will not only affect the quality of the product, and will cause the mould in serious waste of materials, processing time and cost, greatly increase the cost of product and reduce the production efficiency, serious impact on the competitiveness of the products.Research shows that the service life of mould and inappropriate improper heat treatment, material selection, mold structure is not reasonable, unreasonable mechanical processing technology, mould lubrication is not good, and poor design level of many factors.According to the analysis of the die for large failure statistics, in the cause of die failure factors, the improper heat treatment accounted for about 45%, improper material selection, mold structure is not reasonable account for about 25%, process problems accounts for about 10%, lubrication problems, equipment factors accounted for about 20%.Therefore, in the mold design and manufacturing process, choose appropriate material, the reasonable die structure design, selection and reasonable heat treatment process, the processing technology of the mould the parts shall be properly arranged route, improve the mould working conditions, improve the quality and the service life of the mold
