摘要
基于CAE软件采用正交试验设计方案对微注射成型工艺参数如模具温度、熔体温度、注射速率、保压压力、保压时间及冷却时间等与微齿轮制件质量的关系进行了数值模拟,并利用直观分析法和方差分析法对模拟结果进行了分析。结果表明,当模具温度为40℃、熔体温度为225℃、注射速率为10 cm3/s、保压压力为100 MPa、保压时间为1 s、冷却时间为20 s时,制件的质量最优,其翘曲量为0.0118 mm,收缩率为0.2897%。
Based on CAE software and using the orthogonal design programs, the relationship of micro-injection molding process parameters such as mold temperature, melt temperature, injection speed, packing pressure, packing time and cooling time etc. and the quality of micro-gear parts was simulated. By using visual analysis and variance analysis method, the simulation results were analyzed. The results showed that when the mold temperature was 40℃, the melt temperature was 225℃, the injection rate was 10 cm^3 / s, the holding pressure was 100 MPa, holding pressure time was 1 s, the cooling time was 20 s, the quality of the parts was best, the warpage was 0.118 mm, and the shrinkage rate was 0. 2897%.
