摘要

摘要塑料注射成型过程中，注塑模具表面在填料的冲击下容易发生侵蚀和磨损，导致模具过早失效。填料对模具的侵蚀磨损机理尚未明确。采用数值模拟的方法，研究了侵蚀速度、侵蚀角、温度、颗粒形状等环境参数和颗粒特性对侵蚀磨损过程的影响。结果表明，冲蚀速度和冲蚀角是影响冲蚀磨损的重要因素。最后，从能量的角度研究了颗粒能量变化与材料冲蚀磨损的关系。

Investigation of erosion wear performance and mechanism of mold materials

Abstract The surface of an injection mold is prone to erosion and wear under the impact of the filler during plastics injection molding, which leads to premature failure of the mold. The mechanism of erosion and wear of a filler on the mold has not been clarified yet. A numerical technique was employed to simulate the erosion and wear process, and the influence of environmental parameters and particle characteristics, such as erosion velocity, erosion angle, temperature, and particle shape were studied. The results showed that the erosion velocity and erosion angle are important factors that affect erosion and wear. Finally, the relationship between change of particle energy and erosion and wear of the material is studied from the perspective of energy.
