The invention discloses a machining method of a special lower die and a surface die thereof for 5G case bending. The special lower die and the surface die thereof comprise a base, a first machine shell, a first hydraulic cylinder, a first connecting block, a first containing groove, a connecting shaft, a second connecting block, a first connecting rod, a first spring, a second connecting rod, a first male die, a second male die, a second spring, a material box, a sliding groove, a push block, a third connecting block, a second containing groove, a telescopic rod, a guide block, supporting feetand a conveying belt. The method comprises the following steps: step 1, inspection; step 2, feeding; step 3, bending; and step 4, discharging. According to the designed case bending die, the bendingprocedure is simplified, rapid bending can be achieved in cooperation with a case plate body, the production efficiency is greatly improved, an automatic feeding device is designed for the material box and can provide the case
