And it also reflects the level of one country’s industry. With the application of molding CAD/ CAE/CAM，Injection mold design and manufacturing has made breakthrough progress . Greatly improved mold quality and production efficiency. The mould design with the mobile phone cover for research object，designed model and the parting surface based on P/E and optimized the analysis of mould based on Moldflow software. Based on this, this paper mainly studies the following several aspects: Firstly， Introduced the characteristics of the forming process of ABS material; and analyzed the characteristics of process on the mobile phone cover. Then, using Pro/E designed the parting surface and the standard formwork. And using Moldflow determined the best location of the region, flow analysis ,warping analysis, and cooling analysis etc, and by optimizing the parameters obtained reasonable results, engineering change was done. After that , analyzed and calculated the structure of the mold forming part, and simply introduced the working principle of the mould. Finally, based on the correlation analysis and the calculation , the mobile phone cover injection mould design was completed.
