Provided is a mold cleaning system. When cleaning a mold, the mold cleaning system acquires three-dimensional image data of a molding surface of the mold by a camera and, on the basis of the acquired image data, the mold cleaning system controls the movement of arms using a control device, moves a laser head along the molding surface while irradiating with a laser beam supplied by a laser oscillator and, as a result, removes dirt adhered to the molding surface.

An object of the present invention is to provide a production method of a cover for mold cleaning which can clean a mold without removing the mold from a vulcanizer and is excellent in a mold cleaning effect while maintaining productivity. The production method of a cover for mold cleaning is produced by applying an unvulcanized rubber composition on an outer periphery of a raw cover, the method comprising a rubber strip winding step of winding a rubber strip consisting of the unvulcanized rubber composition from side wall portions to tread shoulder portions of a raw cover, and a plate-like rubber material winding step of applying a plate-like rubber material consisting of the unvulcanized rubber composition on a tread center portion of the raw cover, wherein a gauge of the rubber composition after vulcanization of the cover is not less than 1.0 mm.
