Cooling device for producing gray cast iron

The invention discloses a cooling device for producing gray cast iron. The cooling device comprises a base. Sliding grooves are symmetrically formed in the two sides of the upper surface of the base.Sliding blocks are mounted in the two sliding grooves in a sliding manner correspondingly. A driving motor is mounted at one side of the upper surface of the base, and a support plate is mounted at the other side of the supper surface of the base. The sliding grooves are formed between the driving motor and the support plate. A rotating shaft is connected to an output shaft of the driving motor. The end, far away from the output shaft, of the rotating shaft is rotatably connected to the support plate. Lead screws are symmetrically arranged at the two sides of the rotating shaft. A lead screw nut block is in threaded connection to each lead screw. A sliding block is connected to the side wall of each lead screw nut block. A connecting rod is fixed to the side wall, far away from the corresponding sliding bock, of e
