摘　　要：系统地介绍了微型注塑机注塑单元的结构形式,分析了各种注塑单元的特点;研制了一种基于精密齿轮泵的微分注塑机,详细地阐述了微分注射成型的机理,对比了微注射成型和微分注射成型的基本工艺流程;通过试验初步检验了微分注射成型效果。结果表明,微分注射成型可高效率地成型微型制品。The configuration and characters of several microinjection molding plasticizing units were systematically introduced. A novel concept of multi microinjection molding system was presented. The system was designed as a multi microinjection module, which was matched with a vertical injection molding machine and applied in common injection molding machines. The mechanism and basic process of the multi microinjection molding was stated; via the multi microinjection molding, multiple microparts were obtained. The molding experiment indicated the efficient microinjection capability of the multi microinjection molding machines.
