| Summary: | The Box-Behnken method in the response surface method was used to design and analyze the experiment. A multi-factor quadratic polynomial ma-thematical model of the homogenization section screw structure and extrusion effect of the rubber injection machine was established. The influence of the homogenization section screw structural para-meters on the extrusion effect and their interaction were discussed. The regression equation obtained from the experiment was used to optimize the homogenization section structural parameters of the rubber injection machine rod. The results showed that the difference between the predicted values of each parameter obtained by simulation and the si-mulated values was within 2%. The optimal parameters were the screw groove depth of 8.29 mm, screw pitch of 60.17 mm, and screw peak axial width of 5 mm. At this time, the standard deviation of the outlet temperature was reduced by 3.5%, and the temperature uniformity of the screw homogenization section improved; the average outlet velocity was increased by 9.7%, and the plasticizing capacity improved significantly.
