Production process for conveniently casting copper squirrel cage rotor

The invention discloses a production process for conveniently casting a copper squirrel cage rotor. The production process comprises the following steps: (1) a silicon steel sheet pretreatment process; (2) the laminated silicon steel sheets are loaded into a preheated mold cavity to be continuously heated; (3) heating the laminated silicon steel sheet to 650-750 DEG C, and putting the silicon steel sheet into a centrifugal machine; (4) smelting a copper material, wherein the copper material is pure copper or a high-copper-content alloy; (5) molten copper obtained after smelting is poured into a mouse cage groove of the high-temperature silicon steel sheet placed in the centrifugal machine and a mold cavity, and the centrifugal machine is started to rotate and exhaust; (6) cooling: taking out the die-cast copper rotor of the motor, putting the die-cast copper rotor into room temperature water, cooling for 1 minute, and taking out the die-cast copper rotor for air cooling; the three-phase asynchronous motor rot
