Abstract
Injection molding plastic molding is the main method of Thermo plastic molding. It can form complex precision plastic parts by one action. The mobile phone industry's rapid development requires mobile phone casing quickly update. The paper design a injection mold for a cell phone battery’s back, make the analysis the structure of the process for the part. The author Determined the type face, the pouring system,chosed the injection machine, calculated the size of the molding components.This mold use a side gate what plastic is put in. And use the core-pulling mechanism,what achived the successful release of products. So the structure can be designed to ensure that a reliable mold work. Finally, make the structure and mold injection machine to match the check.And then drawed a mold assembly and parts drafting with AutoCAD .
