一般塑料模具用正火的45和40Cr经调质后制造,因而模具硬度低、耐磨性差,表面粗糙度值高,加工出来的塑料产品外观质量较差,而且模具使用寿命低。
The general plastic mold is made of normalized 45 and 40Cr after quenching and tempering, so the hardness of the mold is low, the wear resistance is poor, the surface roughness value is high, the appearance quality of the processed plastic products is poor, and the service life of the mold is low.
精密塑料模具及硬度高塑料模具采用CrWMo、Cr12MoV等合金工具钢制造,不仅机械加工性能差,而且难以加工复杂的型腔,更无法热处理变形问题。
Precision plastic mold and high hardness plastic mold are made of alloy tool steel such as crwmo and Cr12MoV, which not only has poor mechanical processing performance, but also is difficult to process complex cavity, and can not solve the problem of heat treatment deformation.
塑料模具钢的具有以下特点
Plastic die steel has the following characteristics
1.塑料模具用钢涵盖广泛,从普通钢材到专用钢才都有。这在塑料模具初期更加明显,如今已日趋正规和。专门用钢已自成体系,模具用钢的化学成分和合金工具钢的基本相同,但其冶金质量更高,加工精良,对热处理有利。
1. Plastic mold steel covers a wide range, from ordinary steel to special steel. This is more obvious in the early days of plastic mold, and now it has become more and more formal and advanced. The chemical composition of die steel is basically the same as that of alloy tool steel, but its metallurgical quality is higher and its processing is better, which is beneficial to heat treatment.
2.塑料模具钢性能要求严格,热处理难度大。
2. The performance of plastic mould steel is strict and the heat treatment is difficult.
3.为避免模具零件在强韧化过程中的变形或其他热处理问题,模具钢以预硬化形式供应市场已较普遍。
3. In order to avoid deformation or other heat treatment problems in the process of strengthening and toughening, die steel has been widely supplied to the market in the form of pre hardening.
4.以石化产品为原料的塑料制品,某些度不同的腐蚀性,所以耐蚀钢应用也较多。
4. Plastic products with petrochemical products as raw materials have different degrees of corrosivity, so corrosion-resistant steel is widely used.
5.配合预硬化钢、非调质刚的应用,易切sb5_23g削性也是塑料模具钢的特点
5. With the application of pre hardening steel and non quenched and tempered steel, it is easy to cut sb5_ The machinability of 23g is also a characteristic of plastic die steel
