摘　　要：分析了超声波施加方式对微制品上微结构成型质量的影响机理。通过可视化试验用高速摄像机实时观测记录聚合物熔体在模具型腔微结构处的充模流动与凝固定型,设计了一种以反射光方式观察超声波引入微制品注射成型过程的可视化模具。并对石英玻璃窗口进行了受力分析,以确保作为可视化窗口的石英玻璃在注射成型试验中不会被型腔内的聚合物熔体充模压力所破坏。The influence of ultrasonic vibration ways on the forming quality of micro-injec- tion plastics was analyzed. Through visualization tests that a high-speed camera was used to record the flowing and solidification of polymer melt in the micro-structure of mould cavity. A visualization mould was designed by which the injection process could be ob- served with the reflected light when ultrasonic vibration was introduced into the micro-in- jection process. And the strength of the quartz glass was analyzed in order to ensure it won＇t be destructed by pressure of the polymer melt flowing in the cavity.
