The invention belongs to the field of mold machining, and particularly relates to mold grinding and cleaning equipment which comprises a base. A transmission plate is arranged at the top of the base, two supporting plates are fixedly connected to the top of the base, the top ends of the two supporting plates are fixedly connected with the same top plate, a first motor is fixedly mounted at the top of the top plate, the same lifting plate is rotatably mounted on the sides, close to each other, of the two supporting plates, a second motor is fixedly mounted at the top of the lifting plate, a rotating hole is formed in the lifting plate, a grinding shaft is rotatably mounted in the rotating hole, a grinding wheel is fixedly connected to the bottom end of the grinding shaft, the grinding shaft cooperates with the second motor, two clamping mechanisms are arranged at the top of the base, and the two clamping mechanisms cooperate with the first motor. During use, a mold can be simply and conveniently fixed so that the mold cannot shake during grinding, the grinding quality is improved, the air pressure in an air storage tank can be indirectly increased during rotation of the grinding wheel, and therefore the purpose of flushing the mold through the air pressure is achieved.
