Forming method of casting wax mould of super-variable cross-section integral guider

The invention discloses a forming method of a casting wax mould of a super-variable cross-section integral guider, and the forming method is used for moulding of a double-layer bidirectional structure guider which comprises an inner ring, an outer ring and a blade ring with a super-variable cross-section, and the blade ring of the double-layer bidirectional structure guider is extracted into a support wax mould with a small variable cross-section. The method comprises the following steps of: forming a support body wax mold, performing secondary pouring on the support body wax mold to form a blade ring wax mold with a super-variable cross section, integrally stripping the blade ring wax mold in a loose piece linkage manner, effectively improving the forming precision and the working efficiency, and simultaneously pressing an inner ring wax mold and an outer ring wax mold which are integrally formed by adopting a mold, and then the blade ring wax mold, the outer ring wax mold and the inner ring wax mold are com
