注塑成型工艺对显示器结构件力学性能的影响
|
摘要
以某显示器结构件为研究对象,注塑件在工作状态下的Mises应力值为评价指标,结合注塑成型数值仿真和结构分析数值仿真,采用正交设计、极差和方差分析方法,获得了最佳工艺参数组合。进行了单因素变动实验,研究了单工艺参数对注塑件力学性能的影响。结果表明:随熔体温度的升高、模具温度的降低、保压压力降低和保压时间的减少,该结构件在工作状态的Mises应力会增大。研究结果对提高注塑件的结构分析精度和指导注塑工艺参数的选取具有一定的参考价值。
Taking a plastic structural components of displayer as the study object and the Von Mises stress value under the working condition as the optimization objective,combining injection molding numerical simulation with structural analysis numerical simulation,using the orthogonal design,range analysis and variance analysis methods,optimal injection molding process parameters were determined. The single factor change tests were conducted to study the influence of the single process parameter on mechanical property of plastic. The results showed that the Von Mises stress value of this structure under the working condition increased with the increase of melt temperature and the decrease of mold temperature,packing pressure and packing time. The results of the study had some reference value in respect of improving the structural analysis accuracy of injection molding parts and guiding the choice of molding process parameters.
