PROBLEM TO BE SOLVED: To provide a quick molding method for a ceramic casting mold, which quickly dries and cures a binder in a short period of time even when the solution of a zirconium compound such as ammonium zirconium carbonate or zirconium acetate is used as a binder, and which has excellent productivity. SOLUTION: In a molding method for a ceramic casting mold, after wax is immersed in slurry containing a binder and aggregates, the surface of the mold is coated with the slurry, and sprinkling of refractory sand on the coated surface and drying of the wax are repeated. Then dewaxing and baking are performed to mold a ceramic casting mold. Ceramic slurry containing a zirconium compound solution as a binder and zirconia as an aggregate is used for the slurry for at least a first layer, and ozone is used in the drying after the coating so as to cure the binder.
