（1）. Meetsthe requirements of working conditions
- Ketahanan pakai
Apabila kosong adalah plastik dalam rongga acuan, permukaan rongga mengalir dan meluncur di sepanjang permukaan rongga, yang menyebabkan geseran antara permukaan rongga dan kosong, which causes the die to fail because of the wear. So the wear resistance of the material is one of the most basic and important properties of the mold.
Hardness is the main factor affecting the wear resistance. Secara umum, the higher the hardness of the die parts, the less the wear, the better the wear resistance. Sebagai tambahan, rintangan haus juga berkaitan dengan jenis, kuantiti, bentuk, saiz dan pengagihan karbida dalam bahan.
2, strength and toughness
Most of the working conditions of the dies are very bad, and some of them often bear a large impact load, mengakibatkan keretakan rapuh. In order to prevent the sudden brittle fracture of die parts, the die must have high strength and toughness.
Keliatan acuan bergantung pada kandungan karbon, saiz bijirin
and microstructure of the material.
- Fatigue fracture properties
During the working process of dies, fatigue fracture often occurs under the long-term effect of cyclic stress. Its forms are low energy multiple impact fatigue fracture, tensile fatigue fracture contact fatigue fracture and bending fatigue fracture.
The fatigue fracture properties of the die mainly depend on its strength, kekuatan, kekerasan dan kandungan kemasukan dalam bahan.
4, high temperature performance
When the working temperature of the die is higher, the hardness and strength of the die will decrease, resulting in early wear or plastic deformation of the die and failure. Because the mold material should have high tempering stability to ensure that the mold at the working temperature, with high hardness and strength. 5. Resistance to cold and hot fatigue
Some moulds are in the state of repeated heating and cooling in the working process, making the surface of the cavity under the action of tension and stress, causing surface cracking and peeling, meningkatkan geseran, hindering the plastic deformation and reducing the size accuracy, resulting in the failure of the mold. Cold and hot fatigue is one of the main failure modes of hot working dies, which should have high cold and hot fatigue resistance.
- Rintangan kakisan
Some molds, such as plastic moulds in the work, because of the existence of chlorine, fluorin dan unsur-unsur lain dalam plastik, decomposed and precipitated HCI, HF and other strong erosive gases after heating, eroding the mold cavity surface, increasing the surface roughness and aggravating the wear failure.
(2) Meets the requirements of the process performance
Mould manufacturing generally has to go through forging, memotong, heat treatment and other processes. Bagi memastikan kualiti pembuatan acuan dan mengurangkan kos pengeluaran, the material should have good Forgability, kebolehmesinan, kebolehkerasan, hardenability and grinding property; it should also have small oxidation, decarburization
sensitivity and quenching dehiscence tendency.
- Forgability
Ia mempunyai rintangan ubah bentuk penempaan panas yang rendah, keplastikan yang baik, julat suhu penempaan yang luas, low tendency of cold cracking and precipitation of network carbide.
- Annealing process
Julat suhu penyepuhlindapan spheroid adalah luas, kekerasan penyepuhlindapan adalah rendah dan julat turun naik adalah kecil, dan kadar spheroidizing adalah tinggi.
3, kebolehmesinan
Parameter pemotongan besar, low tool loss, low surface roughness.
4, oxidation and decarburization sensitivity
Apabila dipanaskan pada suhu tinggi, the oxidation resistance is good, the decarbonization rate is slow, and it is insensitive to the heating medium, so the tendency of pitting is small.
- Kebolehkerasan
Selepas pelindapkejutan, ia mempunyai kekerasan permukaan yang seragam dan tinggi.
6, kebolehkerasan
A deeper hardening layer can be obtained after quenching, and the hardening can be achieved by using a moderate quenching medium.
7, the tendency of quenching and dehiscence
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.
8, grindability
The relative loss 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 condition, and is not easy to occur grinding damage and grinding cracks.
(3) Meets the economic requirement
In the selection of die materials, we must consider the principle of economy, as far as possible to reduce manufacturing costs. Oleh itu, under the premise of satisfying the service performance, the first choice of low price, can use carbon steel without alloy steel, can use domestic materials without imported materials. Sebagai tambahan, the production and supply of the market should also be taken into account in the selection of materials, the selected steel should be as few and centralized as possible, easy to buy.
