[0002] The mobile phone back shell parts have high requirements on the texture and appearance of the mobile phone metal shell, and no defects are allowed. The R arc surface of the mobile phone appearance is the key control point of the mobile phone appearance processing. The traditional idea is to spend a lot of time on polishing after processing, and the processing qualification rate is only 10% in mass production. Reason: Due to the combined influence of factors such as tool installation error, tool handle runout, tool error, tool life, processing strategy, tool selection, etc., the trend of mobile phone appearance requirements is shifting towards metalization. The surrounding of the mobile phone is designed with R arc lines, and a tool for processing the appearance must be designed. Designing special processing tools according to the R arc surface of the mobile phone appearance is the easiest way to ensure the tolerance requirements of the parts, with high processing efficiency, reduced polishing workload after processing, and low processing cost. It is the first processing idea;

[0003] The blade structure of the existing mobile phone appearance molding tool is fixed. When in use, the cutting angle needs to be changed by a machine to complete the rounded corner molding cutting. The operation is more troublesome and it is difficult to control the cutting accuracy. Therefore, we introduce a new mobile phone appearance molding tool. Utility Model Content
