| 为解决橡胶注射成型机胶料的塑化质量差的问题，对螺杆结构参数进行优化设计和有限元模拟分析。基于522C008螺杆的结构参数优化设计的522C03901螺杆的长径比不变，而几何压缩比、螺旋升角、螺距、槽深和棱宽减小，采用有限元模拟分析和试验验证得出：与522C008螺杆相比，胶料的注射成型过程中522C03901螺杆的最高塑化温度、出口平均温度和出口最高温度升高，出口平均压力增大，注射成型的胶条的表面光滑，没有焦烧现象，即522C03901螺杆的塑化效果更好。 |

| To solve the problem of poor plasticizing quality of the compound in rubber injection molding machine，the optimization design and finite element simulation analysis of the structural parameters of the screw were carried out.Based on the structural parameters of the 522C008 screw，the optimized design 522C03901 screw maintained the same length-to-diameter ratio，while the geometric compression ratio，helix angle，pitch，groove depth and rib width were reduced.Finite element simulation analysis and test verification revealed that，compared with the 522C008 screw，during the injection molding process of the compound，the maximum plosticizing temperature，average outlet temperature and maximum outlet temperature of the 522C03901 screw increased，average outlet pressure was improved.The injection molded rubber strip displayed a smooth surface without scorching，indicating that the 522C03901 screw delivered superior plasticizing effect. |
