Zusammenfassung:	The invention provides a design method of investment precision casting chilling blocks, and the design method comprises the following steps that materials of the chilling blocks are selected, and the sizes of the required chilling blocks are determined according to the size of a hot spot part of a casting; according to the shape of the hot spot part, the shapes and the number of the chilling blocks are determined, and the number of the chilling blocks is not less than 2; the fixing positions and the fixing modes of the chilling blocks on a shell are determined in combination with the shell structure; according to a wax mold structure, the fixing mode of the chilling blocks and a wax mold is determined; and according to the shrinkage characteristics of the chilling blocks, the gap value between the chilling blocks is determined. According to the design method provided by the invention, a solution thought is provided for placement of the investment precision casting built-in chilling blocks, the problem of loos
