摘要
基于正交实验设计方法,对微连接器在不同的微注射成型工艺参数下的充填情况进行研究,选择制品的质量作为实验指标,确定模具温度、熔体温度、注射速度、保压压力、保压时间、冷却时间等6个工艺参数为实验因素,通过对实验数据进行极差分析,得到了各因素对指标值的影响的主次顺序。实验结果表明,模具温度是影响制品质量精度的主要工艺参数因素,而冷却时间的影响最小。通过因素水平影响趋势图分析,得出了微连接器的最优工艺参数组合方案为模具温度80℃、熔体温度335℃、注射速度100 mm/s、保压压力20 MPa、保压时间1.5 s、冷却时间3.0 s,为微型器件生产中的工艺设计提供了理论依据和实际指导。
Based on the orthogonal experimental method, micro-injection molding processes of micro-connectors with various processing parameters were studied. The weight of micro plastic part was selected as the experimental indicator. Six processing parameters, mold temperature, melt temperature, injection velocity, packing pressure, packing time, and cooling time were taken as influencing factors. The order in importance of the influencing factors was determined through range analysis （RS）. The mold temperature was the most important process parameter, and the cooling time was the least important process parameter. According to the change trends of factors and levels, the optimized process parameter scheme was mold temperature 80℃, melt temperature 335℃, injection velocity 100 mm/s, packing pressure 20 MPa, packing time 1.5 s, and cooling time 3.0 s, which could be taken as a reference in the process design of micro plastics parts.
