The service life of the die-casting mouldand die-casting mould materials are closely related.Die casting parts mainly divides into contact with metal parts, sliding parts and die set structure parts.Casting die cavity and sprue parts in metal pressure casting process, direct contact with high temperature and high pressure, high speed of liquid metal.On the one hand wash directly by metal corrosion, abrasion, high temperature oxidation and the various: on the other hand, due to the high efficiency production, mold temperature rise and fall is very severe, and forming a cyclical changes.Therefore, die-casting die steel requires higher thermal fatigue resistance, heat conductivity and good wear resistance, corrosion resistance and high temperature mechanical properties.
Die casting mould material, mainly according to the temperature of the casting metal and the kind of casting metal.The higher the temperature, the destruction of the die casting mould and the more serious the wear.Because of the die-casting die parts work under different conditions, the impact of cast metal and wear is also different, so the die mold hardness requirements should be according to the purpose of the parts and varies from one of the cast metal.For example, to severe wear parts, should have a higher hardness;Parts of work under heating condition, should have higher thermal fatigue resistance and high temperature performance.Table 1 is a factory of die mold hardness requirement, for reference.GeChang requirements of different hardness, should according to specific situation.
