Abstract: PURPOSE: A method for forming a water jacket core for cylinder block casting is provided to prevent damage during forming due to thickness difference of the core by forming the insert core after interposing an insert core between each cylinders of a water jacket core forming a cooling water passage of an engine at outside the cylinders. CONSTITUTION: In a method for forming a water jacket core for cylinder block casting in which the water jacket core(1) for cylinder block casting assembled between a bore core and front, rear, left and right side cores is manufactured, the method comprises a first step(S1) of forming an insert core(9) for mounting the insert core(9) onto a tiller part of a water jacket core(1) corresponding to a space between each cylinders; a second step(S2) of installing the insert core(9) formed in the first step at a corresponding position between each cylinders of a whole water jacket core mold(11); and a third step(S3) of forming a water jacket core finished product by blowing after injecting mold sand into the water jacket core mold(11), wherein the insert core(9) is consisted of a sand tiller made of the mold sand.
