摘　　要：针对塑料微齿轮注射成型工艺,选用POM和ABS两种塑料,对影响熔体充填率的主要工艺参数:熔体温度、模具温度、注射速率和注射压力进行了数值模拟分析。利用单因素试验法进行了仿真,初步得到了两种塑料成型时的充填率都随着各个工艺参数的增加而提高;POM能得到较好的充填率,但ABS几乎都没有填充到型腔,不适合注射微齿轮。利用正交试验法对POM塑料齿轮的成型工艺参数进行了仿真,通过极差分析和方差分析,得到了各个工艺参数对充填率的影响程度,获得了微齿轮注射成型的最佳工艺参数组合。The plastic injection molding process for micro-gear was researched.The main process parameters influencing the micro-gear space ratio included injection temperature,mold temperature,injection rate and injection pressure was simulated,for two different plastic POM and ABS.With single factor experiment method,the preliminary conclusion is that space ratio improved by the increase of the process parameter;POM can get high space ratio;while ABS almost can’t get to the cavity,so ABS is not suitable for injecting micro-gear.With orthogonal experiment,the process parameters of POM micro-gear were simulated.Based on the range analysis and variance analysis,the influence degree of the process parameters to the space ratio is obtained,and the optimum technological parameters are gained.
