What are the technical performance requirements for injection mold processing?
Injection mold processing generally requires several processes such as forging, cutting, and heat treatment. In order to improve the manufacturing quality of the mold and save production costs, its materials should have good forgeability, machinability, hardenability, hardenability, and grindability; it should also have small oxidation, decarburization sensitivity and quenching deformation Cracking tendency.
The injection mold has low resistance to hot forging deformation, good plasticity, a wide forging temperature range, and low tendency to forge cracking, cold cracking, and precipitation of network carbides.
2, annealing processability
The spheroidizing annealing temperature range is wide, the annealing hardness is low, the fluctuation range is small, and the spheroidizing rate is high.
Large amount of cutting, low tool wear and low surface roughness.
4.Sensitivity to oxidation and decarburization
When heated at high temperature, the oxidation resistance is good, the decarburization speed is slow, it is not sensitive to the heating medium, and the tendency of pitting is small.
After quenching, it has uniform and high surface hardness.
After the injection mold is quenched, a deeper hardened layer can be obtained, and it can be hardened with a mild quenching medium.
7, quenching deformation and cracking tendency
The volume of conventional quenching is small, the shape is warped, the distortion is slight, and the tendency of abnormal deformation is low. The cracking sensitivity of conventional quenching is low, and it is not sensitive to the quenching temperature and the shape of the workpiece.
The relative wear of the grinding wheel is small, the grinding amount is large, it is not sensitive to the quality of the grinding wheel and the cooling conditions, and it is not easy to wear and crack.
