TPE射出成形の一般的な欠陥の解決策. Meetsthe requirements of working conditions
- 耐摩耗性
TPE射出成形の一般的な欠陥の解決策, TPE射出成形の一般的な欠陥の解決策, TPE射出成形の一般的な欠陥の解決策, 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. 一般に, the higher the hardness of the die parts, the less the wear, the better the wear resistance. 加えて, 耐摩耗性もタイプに関連しています, 量, 形, 材料中の炭化物のサイズと分布.
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, 脆性破壊をもたらす. In order to prevent the sudden brittle fracture of die parts, the die must have high strength and toughness.
金型の靭性は主に炭素含有量に依存します, 粒度
and microstructure of the material.
- 疲労破壊特性
During the working process of dies, 疲労破壊は、繰り返し応力の長期的な影響下でしばしば発生します. 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, 靭性, 材料の硬度と介在物の含有量.
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, 摩擦の増加, 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.
- 耐食性
Some molds, such as plastic moulds in the work, because of the existence of chlorine, プラスチック中のフッ素およびその他の元素, 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, 切断, 熱処理およびその他のプロセス. 金型の製造品質を確保し、製造コストを削減するために, the material should have good Forgability, 機械加工性, 硬化性, hardenability and grinding property; it should also have small oxidation, decarburization
sensitivity and quenching dehiscence tendency.
- Forgability
熱間鍛造変形抵抗が低い, 良好な可塑性, 広い鍛造温度範囲, low tendency of cold cracking and precipitation of network carbide.
- Annealing process
球状化焼鈍温度範囲が広い, 焼鈍硬さが低く、変動幅が小さい, かつ球状化率が高い.
3, 機械加工性
大きな切削パラメータ, low tool loss, 低表面粗さ.
4, oxidation and decarburization sensitivity
高温で加熱すると, 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.
- 硬化性
焼入れ後, それは均一で高い表面硬度を持っています.
6, 硬化性
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
従来焼入れの体積変化が少ない, 形状の反り、歪みが少ない, 異常変形の傾向が少ない. 従来の焼入れは割れ感受性が低く、焼入れ温度やワーク形状の影響を受けにくい.
8, grindability
The relative loss of grinding wheel is small, ヤケのない限界研削量が大きい, 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. したがって、, 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. 加えて, 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.
