BMC注射螺杆螺槽内温度分布的研究

Study on Temperature Distribution in Channel of Screw for BMC Injection Molding

本文采用了非等温的二维流动数学模型，首次研究了ＢＭＣ材料在注射螺杆螺槽内的温度分布规律，找出温度分布与注射成型加工参数（螺杆转速、背压等）的关系，结果表明平均温度随螺杆转速和背压而变化。

? In this paper, with establishing mathematical model for nonisothermal 2D flow, the temperature distribution in channel of screw for BMC injection molding was studied. The dependence of the temperature distribution on the other process parameters (screw speed, back pressure) were discussed. The results showed that the mean temperature changes with the screw speed and back pressure.
