With the development of 4.0 industry, the application of oem plastic mold is inseparable in industrial production and people's lives, and custom injection molding tooling parts as an important part of the mold are closely related to the mold. Mold accessories are widely used in various manufacturing fields, such as plastic molds, stamping molds, automobiles, electrical and aviation. The quality characteristics of injection molding die parts are determined by the quality and service life of the mold. The wear resistance of mold parts absolutely affects its characteristics is the hardness of the mold parts. Generally, the higher the hardness of the mold parts, the smaller the amount of wear and the better the wear resistance. In addition, wear resistance is also related to the type, quantity, shape, size and distribution of carbides in the material.
1. Strength
Most of the working conditions of injection molding tooling are very bad, and some of them are often subjected to larger impact loads, which leads to brittle fracture. In order to prevent sudden brittle fracture of mold parts during work, the mold must have high strength and toughness. The toughness of the mold mainly depends on the carbon content, grain size and organization state of the material.
2. Wear resistance
When the blank is plastically deformed in the mold cavity, it flows and slides along the surface of the cavity, causing violent friction between the surface of the cavity and the blank, which causes the mold to fail due to wear. Therefore, the wear resistance of the material is one of the most basic and important properties of the mold.
3. Fatigue fracture performance
During the working process of the mold parts, under the long-term action of cyclic stress, fatigue fractures are often caused. Its forms include low-energy multiple impact fatigue fracture, tensile fatigue fracture, contact fatigue fracture, and bending fatigue fracture.
