Do you know the main features of mold parts?

2019-11-27


Wear resistance: when the blank is plastic in the mold cavity, it flows and slides along the surface of the mold cavity, causing severe friction between the surface of the mold cavity and the blank, resulting in the failure of the mold due to wear. So the wear resistance of the material is one of the most important properties of the mold parts.
Strength and toughness: most of the working conditions of the die are not good, some of them often bear large impact load, resulting in brittle fracture. In order to prevent the die parts from breaking suddenly when working, the die parts should have high strength and toughness. The toughness of die fittings mainly depends on the carbon content, grain size and microstructure.
Corrosion resistance: during the operation of the plastic mold, due to the presence of chlorine, fluorine and other elements in the plastic, HCl, HF and other strong corrosive gases are decomposed and precipitated after heating, which corrode the surface of the mold cavity, increase its surface roughness, and intensify the wear failure.
Corrosion resistance: wear resistance and strength and toughness are the three major characteristics of mold accessories, but at present, the production requirements are more and more strict. These three characteristics alone can not meet the application of mold accessories in production. Then, what other characteristics should new mold accessories have?
Anti fatigue and fracture performance: anti fatigue and fracture performance is a kind of performance of new mold accessories now. Because in the high-strength production process, mold accessories are prone to fatigue and fracture under long-term force, so the mold accessories with anti fatigue and fracture performance are now very important, and the anti fatigue and fracture performance of mold accessories depends on its strength Toughness, hardness and the process and materials for making mold accessories.
High temperature resistance: high temperature resistance is a basic performance required for mold accessories at present. Because the mold is constantly in and out of the production line in the process of production, high temperature work will reduce the hardness and strength of mold accessories, so mold accessories with anti tempering stability can ensure the stability of production process and high quality of products in high temperature environment.
