Simulation of micro-gear manufactured by differential injection molding based on Moldex 3D

摘要：

　　In this article,the structure of the differential pump is introduced,which is the core part of the differential injection system.The micro-gear with a shaft collar is simulated as it is an important micro-part and has great potential application in mechanical transmission.The Moldex 3D simulation software is used to investigate effects of processing parameters on the micro-gear such as melt temperature,mold temperature,injection time and packing time etc.By comparing the micro-gears warpage under different processing parameters,it can be concluded that melt temperature has a greater impact on the molding quality than mold temperature.In addition,the effects of injection time and packing time on the micro-gears molding quality are also investigated.
