How to evaluate the technical level of the mold?
The technical level of the mold is ultimately reflected in the following aspects.
① Mold manufacturing cycle
The manufacturing cycle of the mold reflects the technical level and organizational management level of the mold production. When manufacturing the mold, we should try to shorten the mold manufacturing cycle. At present, in order to shorten the mold cycle, computer-aided design mold methods and CNC machine tool processing technology are used.
② Mold life
The mold life refers to the durability of the mold to produce qualified products, which is generally expressed by the number of parts produced by the mold. The correct use, maintenance and storage of the mold have a great impact on the life of the mold. Improving the mold life is a comprehensive technical issue. At present, in addition to studying and correctly selecting the steel used for the mold to improve the mold life, it should also be improved and improved in terms of mold structure, manufacturing process methods, debugging equipment, heat treatment process, lubrication conditions when the mold is used, cooling methods, and the accuracy and maintenance of the equipment used, and the condition of the blank.
③ Mold accuracy
The mold accuracy can be divided into the accuracy required for the parts and the accuracy required to exert the mold efficiency. Such as the parallelism, verticality, positioning and guide matching accuracy of the surface. Its processing accuracy is limited by the processing method and the accuracy of the processing equipment itself. The mold accuracy usually refers to the dimensional accuracy of the convex and concave molds and the surface quality of the formed surface. Factors affecting mold accuracy include: the original accuracy of the mold, the type and structure of the mold, the degree of wear of the mold, the deformation of the mold and the use conditions of the mold.
④ Mold manufacturing cost
The lower the mold cost, the higher the mold technology level.
⑤ Mold standardization degree
Mold standardization is an important measure for specialized production, and it is also an important measure for systematically solving the problem of improving labor productivity, improving product quality and improving labor organization and management. The significance of mold standardization: a. Improve performance and quality b. Save labor time and raw materials, and shorten production cycle. c. Modern production technology requires standardization. d. It can effectively reduce costs and improve benefits.
