基于Moldflow流动模拟的电源按键困气缺陷改善

Improvement of Air Trap Defects of Power Buttons Based on Flow Simulation of Moldflow

选取电视机电源按键为研究对象,针对其表面困气现象,利用Moldflow软件模拟塑料熔体流动的过程,分析熔体流动过程中困气产生的原因和区域,设计并改进该套模具的浇注系统,解决按键表面困气缺陷,实现了模具的改进和产品的顺利生产。

Taking the design of TV power buttons as an example, the formation of air trap defects was analyzed with the help of Moldflow software in simulating the region of air traps generated in the flow process. The runner system of the injection mould was improved so as to eliminate the air trap defects in the surface of the button. As a result, the molding was improved and the mass production of the injection was enhanced.
