High-performance dandruff comb clay sand one-piece casting method

The invention discloses an integral forging method for a high-performance perforated strainer by clay sand, namely a method for molding and forging a high-performance perforated strainer by adopting common clay sand. The invention adopts the following specific proposal that the method comprises the following steps: using the common clay sand as a main molding material, adding 5 to 6 percent of bentonite and 3 to 5 percent of coal dust of the total weight of the clay sand into the clay sand and dry-mixing the materials, adding 3 to 4 percent of water of the total weight of the clay sand into the mixture and blending the mixture to manufacture molding sand, then molding the molding sand by an ejection molding machine with a copper molding die, and finishing the integral forging of the high-performance perforated strainer through the processes of ball-blast cleaning, painting, packing, warehousing, and the like. The method adopts the common clay sand to replace resin sand to integrally forge the high-performance
