由于宏观制件尺寸与微特征尺寸的巨大差别,具有微特征的注塑充填过程是一个典型的几何多尺度结构流动和传热问题.采用数值和解析方法分析了带有微结构注塑成型过程的流动和传热行为,基于有限元/有限差分法动态模拟了宏观充模过程,并用解析法建立了微结构中的充填距离与微结构入口压力、尺寸、流动速度以及材料性质之间的定量关系,详细分析了宏观模温、注射速率及微特征尺寸等因素对微特征填充距离的影响.

Due to the huge difference between macroscopic part size and micro-feature size, the injection molding filling process with micro-feature is a typical geometric multi-scale structure flow and heat transfer problem. The flow and heat transfer behavior of the injection molding process with microstructure was analyzed by numerical and analytical methods, the macroscopic filling process was dynamically simulated based on the finite element/finite difference method, and the quantitative relationship between the filling distance in the microstructure and the inlet pressure, size, flow velocity and material properties of the microstructure was established by the analytical method, and the effects of macro mold temperature, injection rate and micro-feature size on the micro-feature filling distance were analyzed in detail.
