The invention discloses a mold for recoating a multithread cutting machine guide wheel sheet. The mold for recoating a multithread cutting machine guide wheel sheet comprises a convex mold and a concave mold; the middle part of the convex mold is provided with a boss; the working surface of the convex mold is provided with a first seal ring groove; the working surface of the concave mold, which is positioned at the outer edge of the first seal ring groove, is of a wedge-shaped structure, and the working surface of the outer edge of the first seal ring groove is provided with more than two pouring gates; the inner cavity of the convex mold is provided with a second seal ring groove; the first seal ring groove is internally provided with a first rubber seal ring; the second seal ring groove is internally provided with a second rubber seal ring; the boss is mutually adaptive to the central hole of a guide wheel sheet; the first rubber seal ring and the upper end side edge of the guide wheel sheet are in seal fit; the second rubber seal ring and the lower end side edge of the guide wheel sheet are in seal fit. The mold for recoating the multithread cutting machine guide wheel sheet provided by the invention can discharge air bubbles conveniently through the design of the wedge-shaped structure, and can prevent the problems of low coating quality, raw material waste and the like caused by air bubbles.
Description
technical field [0001] The invention relates to solar silicon ingot processing technology, in particular to a mold for recoating guide wheel pieces of various multi-wire cutting square machines. Background technique [0002] The surface of the guide wheel of the multi-wire cutting square machine in the solar energy industry is coated with polyurethane material. After coating the polyurethane material, it needs to be grooved, and the track of the wire mesh is fixed through the opened guide wheel groove to cut silicon ingots. In the process of cutting silicon ingots, the grooves of the guide wheel are easily worn, and when a certain amount of wear and loss is reached, the grooves must be re-grooved. When the polyurethane layer of the guide wheel becomes thinner after repeated slotting, it can no longer be used. At this time, the polyurethane layer must be recoated on the surface of the guide wheel. Now a mold is usually used to recoat the surface of the guide wheel. . [000...
