Design And Manufacture Of Injection Mould For Mobile Phone Outer Shell

Plastic is one kind of new engineerig material. With its rapid development, plastic processing and molding technology have been getting more and more important, and plastics injection molding is the most commom way for polymer processing. The plastic mold has accounted for the great proportion in our daily life. The designs of electronic products' shell become an important link in product quality, especially for cell phone. Injection mould for mobile phone outer shell is the most complex in injection mould and the frame manufacture. Therefore, it has higher practical value to study .The look of mobile phone outer shell demands higher in injection mould and shaping technology for plastics for its small size and complex structure.. Its hardest point lies in the pouring system and demoulding mechanism. The paper is from the practical production and based on large quantity of design and manufacture of injection mould for mobile phone outer shell. It summarizes the practical fruit of the project on the basis of engaging in design of the injection mould for many years. It explores the integral structure design of injection mould of mobile phone outer shell's, the pouring channel, the form of gate and the position in pouring system, the design of vent-centralized slag system, the main stripping mode of major part and the manufacturing methods and technology points. It also takes the combination of face covering and lens for an example to introduce some important ways of practical design and manufacture in detail,which will serve for factories' practice. The defects in practical production and solutions are mentioned in the paper, to help to improve product quality ,and the size, data and mechanical structure are all from factories' practical drawings.
