4.) and the accuracy required for the overall effectiveness of the mold, such as plane parallelism and verticality. It contains both static and dynamic accuracy. The accuracy of the mold can be divided into the accuracy required for mold parts (that is, the accuracy of the forming concave mold and the convex mold, the cavity, etc. Mold standardization degree　　

Mold standardization is an important measure for specialized production, and it is also an important measure to systematically improve laboratory productivity, improve product quality and improve past management. When manufacturing molds, try to shorten the mold manufacturing cycle. Only by continuously expanding the scope of standardized application of molds and organizing specialized production can we fully meet the needs of users and enable molds to be freely purchased and sold in the market like commodities. The accuracy and rigidity of the mold.　　

1, mold manufacturing cycle mold manufacturing cycle reflects the production technology level and organizational management level of the mold enterprise. 3. Accuracy of degree, positioning and guiding coordination. At present, in addition to working hard to study and correctly select the steel used in the mold to improve the service life of the mold, it is also used in mold structure design, manufacturing process methods, debugging equipment, heat treatment process, lubrication conditions when molds are used, cooling methods and accuracy of application equipment And maintenance, blank condition and other aspects to be improved and improved. This requires that in addition to a reasonable selection of mold materials, when manufacturing molds, we must also strive to reduce processing man-hours and save various expenses.　　

For high-speed stamping molds, large-scale stamping forming molds, and precision plastic molds, not only high precision is required, but also sufficient rigidity and no deformation under high-load working conditions. For example, the processing accuracy is limited by the processing method and the accuracy of the processing equipment itself .. Using various methods to design and manufacture various molds can shorten the mold manufacturing cycle by more than 60%. ultimately manifested in many aspects such as mold manufacturing cycle, mold life, mold accuracy and stiffness, mold manufacturing cost, and mold standardization. At present, in order to shorten the mold manufacturing cycle, computer-aided mold design methods and CNC machine tool processing technology are used.

Generally speaking, the mold accuracy mainly refers to the dimensional accuracy of the formed concave mold, OEM plastic household convex mold and cavity. 2, mold service life Providing mold service life is a comprehensive technical problem. Mold manufacturing cost After reaching various technical indicators, the lower the mold manufacturing cost, the higher the mold technology level. 5
