Abstract

This study employed the Taguchi method, analysis of variance, and response surface methodology for plastic gear rack injection molding parameters followed by a factorial quality validation. This study was expected to reduce the time cost of mold design and injection molding by making different combinations of the molding parameters, designing an experimental method, and performing the data simulation experiment by computer-aided engineering (CAE). With the research tool of polymer (polyacetal) for plastic material, computer-aided design mold design, and CAE mold flow analysis software, a numerical analysis of plastic molding flow was conducted. Taguchi L16 (45) orthogonal array designed 16 experimental combinations including injection molding conditions of filling time, holding pressure, holding time, plastic temperature, and mold temperature. The experimental results of molding analysis of software (Moldex3D) determined the optimum molding essentials of plastic injection: filling time 0.2 s, holding pressure 98 MPa, plastic temperature 195 °C, and mold temperature 65 °C. In this study, the parameters of the response surface method were used for the actual injection verification. The CAE simulation software can greatly improve the mold design and injection molding parameter testing time to enhance the overall working efficiency and cost control.

模具流动分析在塑料齿条注塑翘曲研究中的应用

本研究采用田口方法、方差分析和响应面方法对塑料齿条注塑成型参数进行分析，然后进行因子质量验证。本研究旨在通过对成型参数进行不同的组合，设计实验方法，并通过计算机辅助工程（CAE）进行数据模拟实验，从而降低模具设计和注射成型的时间成本。利用塑料材料用聚合物（聚缩醛）研究工具、计算机辅助模具设计和CAE模具流动分析软件，对塑料成型流动进行了数值分析。田口L16（45）正交阵列设计了16个实验组合，包括填充时间、保压、保压时间、塑性温度和模具温度的注塑条件。软件（Moldex3D）的成型分析实验结果确定了注塑成型的最佳成型要点：填充时间0.2 s、保持压力98 MPa，塑性温度195 °C，模具温度65 °C。在本研究中，使用响应面法的参数进行实际注射验证。CAE仿真软件可以大大提高模具设计和注塑参数测试时间，提高整体工作效率和成本控制。
