The present invention relates to a mold for casting an impeller by combination of a top mold and a bottom mold, and, more specifically, to a mold for casting an impeller where the bottom mold comprises: a first mold; and, a second mold piled up on the top of the first mold. The first mold comprises: a body on whose center an inserting hole is formed and which has a settling surface formed around the top end; and, a bottom core formed on the inside of the inserting hole of the body to be one body. The second mold comprises: a supporting plate for getting closer to the settling surface when being piled up and overlapped on the first mold; an inserting unit formed as one body with the supporting plate to be inserted into the inserting hole; and a top core formed as one body with the inserting unit to form a cavity for forming a blade of the impeller between itself and the bottom core. The workability for manufacturing the bottom mold can be improved. |
