description The invention discloses a wax mold for precision casting of a closed centrifugal vane wheel. The wax mold comprises a base plate used for supporting and positioning of the whole mold, the base plate is provided with a lower mold used for forming of a bottom wax mold, a combined mold core used for overall mold filling of all air current channels and a combined upper mold used for forming of an upper wax mold and a lateral wax mold, and a wax mold containing cavity used for enabling the wax mold to be injected and forming the wax mold is formed by the lower mold, the combined mold core and the combined upper mold in an enclosing manner; and the combined mold core is of a complete ring-shaped structure which is formed by closely splicing multiple mold core units used for mold filling of single air current channels in the ring circumferential direction, and the combined mold core is formed by splicing the mold core units through a centering and positioning mechanism used for centering and positioning of the mold
