(1) Cetakan memenuhi kondisi kerja
- Ketahanan aus
Ketika billet didenaturasi plastik di dalam rongga, itu mengalir dan meluncur di sepanjang permukaan rongga, mengakibatkan gesekan yang parah antara permukaan rongga dan billet, which leads to the failure of the mold due to wear. So the wear resistance of materials is one of the most basic and important properties of dies.
Kekerasan adalah faktor utama yang mempengaruhi ketahanan aus. Secara umum, semakin tinggi kekerasan bagian cetakan, the smaller the wear amount and the better the wear resistance. Tambahan, ketahanan aus juga terkait dengan jenisnya, kuantitas, morfologi, ukuran dan distribusi karbida dalam material.
- Strength and tenacity
Most of the working conditions of the mold are very bad, and some of them often bear large impact load, which leads to brittle fracture. In order to prevent the sudden brittle fracture of mold parts, mold should have high strength and toughness.
The toughness of the mold mainly depends on the carbon content, grain size and structure of the material.
- Fatigue fracture properties
During the working process of the mold, fatigue fracture often occurs under the long-term effect of cyclic stress. Its forms include low energy multiple impact fatigue fracture, fraktur kelelahan tarik, patah lelah kontak dan patah lelah lentur.
Kinerja fraktur kelelahan die terutama tergantung pada kekuatannya, kekerasan, hardness and inclusion content in the material.
- Kinerja suhu tinggi
When the working temperature of the mold is higher, the hardness and strength will decrease, leading to early wear or plastic deformation of the mold and failure. Because the mold material should have high tempering stability to ensure that the mold has high hardness and strength at working temperature.
- Cold and thermal fatigue resistance
Some moulds are in the state of repeated heating and cooling in the working process, which causes the surface of the cavity to be tension and pressure variable stress, causes surface cracking and peeling, increases friction, hinders plastic deformation, reduces dimensional accuracy, and leads to mold failure. Thermal and cold fatigue is one of the main failure modes of hot-working mold, which should have high cold and thermal fatigue resistance.
- Tahan korosi
When some moulds such as plastic moulds are working, karena adanya klorin, fluorine and other elements in the plastics, strong corrosive gases such as HCI and HF are decomposed and precipitated after heating, which erode the surface of the mould cavity, increase its surface roughness and aggravate the wear failure.
(2) Mold meets process performance requirements
Mold manufacturing usually goes through forging, pemotongan, heat treatment and other processes. In order to ensure the manufacturing quality of the mold and reduce the production cost, the material should have good malleability, cutting machinability, hardenability, hardenability and grindability, and should also have small oxidation, decarbonization sensitivity and quenching deformation cracking tendency.
- Forgetability
It has low resistance to hot forging deformation, good plasticity, wide forging temperature range, low tendency of cold cracking and precipitation of network carbides.
- Annealing Processing
The spheroidizing annealing temperature range is wide, the annealing hardness is low and the fluctuation range is small, and the spheroidizing rate is high.
- Kemampuan mesin
Large cutting parameters, low tool wear, low surface roughness.
- Sensitivity of oxidation and decarbonization
When heated at high temperature, it has good antioxidant capacity, slow decarbonization speed, insensitive to heating medium and little tendency to produce pitting.
- Hardenability
Setelah pendinginan, it has uniform and high surface hardness.
- Hardenability
Setelah pendinginan, a deeper hardening layer can be obtained, and it can be hardened by using a mild quenching medium.
- Cracking Tendency of Quenching Deformation
The volume change of conventional quenching is small, the shape warpage and distortion are slight, and the tendency of abnormal deformation is low. Conventional quenching has low cracking sensitivity and is insensitive to quenching temperature and workpiece shape.
- Grindability
The relative wear of grinding wheel is small, the limit grinding amount without burn is large, and it is insensitive to the quality of grinding wheel and cooling conditions, so it is not easy to cause grinding damage and grinding cracks.
(3) Mold meets economic requirements
In the selection of mold materials, the principle of economy must be considered to reduce the manufacturing cost as much as possible. Karena itu, on the premise of meeting the service performance, the first choice is low price, carbon steel can be used instead of alloy steel, domestic materials can be used instead of imported materials. Tambahan, the production and supply situation of the market should also be taken into account when selecting materials. The selected steel grades should be as few as possible, concentrated and easy to purchase.
