Kender du de grundlæggende principper for valg af materialer til sprøjtestøbeform? Hvis du stadig ikke ved det, lad os skynde os og se med os.
1. Modstandsdygtighed
Under den plastiske deformation af emnet i matricehulrummet, emnet flyder og glider langs overfladen af matricehulrummet, forårsager friktion mellem overfladen af matricehulrummet og emnet. Derfor, materialernes slidstyrke er en af de mest grundlæggende og vigtige egenskaber ved matricer.
The main factor affecting the wear resistance is hardness. Generelt, the higher the hardness of injection mold parts, the less the wear, and the better the wear resistance.
2. Strength and toughness
Most of the research on working environment conditions of dies are very bad, and some of them often bear shock loads with large capacity, which can lead to brittle fracture. In order to prevent sudden brittle fracture of die design parts during operation, the die shall have relatively high strength and toughness.
The toughness of the die mainly depends on the carbon content, grain size and microstructure of the material.
3. Fatigue fracture performance
In the development process of die design, under the long-term influence of cyclic stress, students can often lead to fatigue fracture. Its forms are small energy through repeated impact fatigue fracture, tensile fatigue fracture, contact fatigue fracture and bending fatigue fracture.
The development of the research on the fatigue fracture system of the die mainly depends on its strength, sejhed, hårdhed, and the content of inclusions in the material.
4. High temperature performance
When the working temperature of the injection mold is high, the strength and hardness will decrease, resulting in wear and deformation. Derfor, a certain degree of anti tempering stability is required.
5. Cold and hot fatigue resistance
Some molds are repeatedly heated and cooled during processing, which causes the cavity surface to be pulled and the pressure changes the stress, causing surface cracking and peeling, increasing friction, hindering plastic deformation, reducing dimensional accuracy, and leading to mold failure. Cold and hot fatigue is one of the main failure forms of hot working dies, which should have high cold and hot fatigue resistance.
6. Corrosion resistance
Some injection molds will appear strong corrosive gas after being heated, which will erode the surface of the mold cavity, increase its surface roughness and intensify wear. Derfor, certain corrosion resistance is required.
