热流道注射模中充模力的计算

Calculation of the Filling Pressure of the Hot-runner Injection Mould

就热流道注射模具 ,根据塑件形状不同 ,分析了熔体在等温流动和非等温流动时 ,流经不同位置时的压力损失。推导出了计算充模压力的数学模型。

According to the different shapes of plastic parts, an analysis was made on the pressure loss at different position when melt plastics flowing in the hot_runner injection mould under isothermal and non_isothermal conditions. The mathematical model for calculating the filling pressure was deduced.
