The cell phone lens is difficult to be produced.This is because of the higher requirement of the injection mould design and manufacture.Through the analysis and research,it was found out that the gate position of the runner system should be selected properly.The sector gate structure should be adopted,whose size should be met with that of the product so as to guarantee the following machining procedure.The design of the exhaust system was very pivotal.Not only four exhaust channels were designed around the plastic part,but also six cold wells were used as deposition,exhaust system and extrusion for plastic part.Three mould plates were adopted on the injection mould and the design of the reinforced pole was added to avoid the mould plate being deformed.The surface quality of the lens was very important.In order to obtain the good surface quality,the matter of the len surfuce buffing of the mould cavity should be set down.It was pivotal that how to choose the technological parameter of the electric spark process.The suitable electrode material should be adopted for the rough and finish machining and the manual polishing was not allowed.
