[0002] At present, the processing of burrs / burrs on the surface of die-cast products of mobile phone middle plates and the treatment of multi-materials basically rely on manual removal or semi-automatic processing and removal with the help of jigs.

This not only affects the assembly production and assembly quality of finished products, but also is difficult to match with the current automated assembly line body, affecting the production efficiency and production cost of finished products. On the other hand, in the current manual or semi-automatic deburring production, due to its low processing efficiency but high cost, it is necessary to improve the forming dimensional accuracy and geometric tolerance in the production of die-cast blanks and enhance the precision of the mold; with the increasing requirements for product quality in the current market, the manufacturing cycle and cost of die-casting molds, the production maintenance cycle and cost have all increased significantly, while the effective production time of the mold has been continuously shortened, and it is difficult to reduce the production cost of die-cast parts.

[0046] As shown Figure 1 in the figure, the integrated process for machining and deburring the middle plate of a mobile phone includes the following steps:

[0047] Step S1 - First punching holes and grooves and / or cutting the burrs on the side walls: Place the upper end of the mobile phone middle frame facing upwards, and punch holes and grooves and / or profile corners and / or cut the burrs on one or more side walls thereof;

[0050] Step S4 - Second punching holes and grooves and / or cutting the burrs on the side walls: Grind the burrs on the surface of the upper end of the mobile phone middle plate and / or the bottom of the groove and / or the side wall of the groove;

[0051] Step S5 - Grinding the burrs on the lower end: Grind the burrs on the surface of the lower end of the mobile phone middle plate and / or the bottom of the groove and / or the side wall of the groove.

[0052] The integrated process for machining and deburring of the present invention integrates the deburring process of die-castings with subsequent machining processes, such as punching holes, reaming holes, trimming and chamfering, etc., arranges them together for processing, optimizes the production process, greatly reduces the production turnover time, reduces the turnover cost and loss, and improves the production efficiency.
