At present, the K211 shell is mostly produced by adopting double-side risers for water feeding and feeding, as shown in figure 1, because the risers occupy most of molten iron, the process yield of the method is relatively low and is about 38 percent all the time, and the process is not easy to be improved upwards. In order to better meet the requirement of product quality, expand the productivity, save the cost and improve the product yield. The common method is to increase the number of cavities and reduce the volume of a sprue cup and a riser, but the number of the cavities cannot be increased due to the limitation of production equipment; meanwhile, if the volume of the pouring cup and the riser is reduced, the quality of the product cannot be guaranteed, so that the production cost and the rejection rate are increased.

Therefore, how to design a riser with as few risers as possible by means of innovative hardware design to meet the requirements of mechanical properties and internal defects of castings, and meanwhile, the process yield is increased to about 50%, the production cost is reduced, and the problem to be solved in the industry at present is urgently needed.
