Med samfundsudviklingen, forme er meget udbredt inden for mange områder. Formdesignere skal have rig erfaring med design og sprøjtestøbning, og skal overveje forholdet mellem disse påvirkningsfaktorer og sprøjtestøbningsbetingelser og deres tilsyneladende faktorer. Because most of the working conditions of molds are poor, molds need to have a lot of performance. Now let’s follow Dj moldingto learn about it.
Folding high temperature performance
When the working temperature of the die is relatively high, it will reduce the hardness and strength, resulting in early wear or plastic deformation and failure of the die. Derfor, the die material should have high tempering stability to ensure that the die has high hardness and strength at working temperature.
Modstandsdygtighed
Når emnet er plastisk denatureret i støbeformens hulrum, det flyder og glider langs hulrummets overflade, resulterer i alvorlig friktion mellem hulrummets overflade og emnet, which will lead to the failure of the mold due to wear. Derfor, the wear resistance of materials is one of the basic and very important properties of molds.
Hårdhed er den vigtigste faktor, der påvirker slidstyrken. Generelt sagt, the higher the hardness of mold parts, the smaller the wear, and the better the wear resistance. Ud over, the wear resistance is also related to the type, antal, form, size and distribution of carbides in the material.
Folding strength and toughness
The working conditions of molds are mostly very bad, and some often bear large impact load, resulting in brittle fracture. In order to prevent sudden brittle fracture of die parts during operation, the die should have high strength and toughness.
The toughness of the die mainly depends on the carbon content, grain size and microstructure of the material.
Folding fatigue fracture performance
In the process of die working, fatigue fracture is often caused by the long-term action of cyclic stress. Its forms include small energy multiple impact fatigue fracture, tensile fatigue fracture, contact fatigue fracture and bending fatigue fracture.
The fatigue fracture performance of the die mainly depends on its strength, sejhed, hardness and the content of inclusions in the material.
Cold and hot fatigue resistance of folding
Some molds are in the state of repeated heating and cooling in the working process, so that the surface of the cavity is under the action of tensile and pressure strain stress, resulting in surface cracking and peeling, increasing friction, hindering plastic deformation and reducing dimensional accuracy, resulting in mold failure. Cold and hot fatigue is one of the main forms of hot working die failure. This kind of die should have high cold and hot fatigue resistance.
Folding corrosion resistance
When some molds such as plastic molds are working, due to the presence of chlorine, fluorine and other elements in the plastic, they decompose and precipitate strong corrosive gases such as HCI and HF after heating, which erode the surface of the mold cavity, increase its surface roughness and aggravate wear failure.
