摘要模具是当代工业制造中关键的加工装备里面之一。在铸造、锻造、冷冲、树脂、 塑胶、玻璃、金属粉末成形、陶瓷等产品制造企业中获得广泛使用。有些制造业发达 国家的模具总产量以超过母机工业的总产量，就这些国家模具市场已摆脱了从属地位 而发展成单独的企业。最近，我国的模具市场亦有了偏大的变化，产品模具制造工艺 和加工设备电子化程度更加高，非常大地提升了模具加工精密度、品质和加工效率。84562

该模具的基本是设计冲模，此模具在预先设计时不但要依据钣金件的材料选择模 具钢材，还要依据钣金件的外形、尺寸公差来决定材料成型模具的类和冷冲的加工规 划。确定合理的冷冲缝隙是该模具的重中之重，它不但影响钣金件的外形、尺寸公差， 还能够影响材料成型模具的工作寿命。在模具钢材的正确选择时应重视材料特性和强 度。理应尽力挑选模具的 准件，如果这样不只能够提升模具使用次数同时能降低材 料成型模具的制作周期。

模具的具体精度十分高在用的历程中要合理的维护，察觉问题要依时的修复，如 果这样就能确保产品的品质，提升模具正常的寿命。

Abstract Mold is one of the key processing equipment inside contemporary industrial manufacturing。 In casting, forging and cold, resins, plastics, glass, metal powder molding, ceramics and other products manufacturing enterprises widely use。 Some developed countries die manufacturing output in excess of the total machine tool industry on these countries to get rid of the mold market has specific subordinate status and the development of a separate enterprise。 Recently, there has been a market motherland mold larger changes in manufacturing processes and the degree of processing equipment, electronic products mold products more high, very earth to enhance the mold precision, quality and efficiency。

The basic design of the mold die, die at this time not only to select a pre-designed mold steel based sheet metal material, but also on the basis of sheet metal shape, dimensional tolerances to determine material mold classes and cold-processing plan 。 Determining phase and reasonable cold-gap is a top priority of the mold, it not only affects the appearance of sheet metal parts, dimensional tolerances, but also can affect the working life of mold material。 Proper mold steel selection should pay attention to the material properties of strength and size。 We should try to choose the mold GB standard parts, if so mold can not only enhance the frequency of use while reducing material mold production cycle。

Specific accuracy of the mold with a very high relative to the course and reasonable maintenance to repair the problem perceived by when, and if so we can ensure product quality, enhance the mold of normal life。
