Novel core setting tool

The utility model relates to the casting industry, provides a novel core setting tool which is simple in structure, convenient to use and capable of conveniently, rapidly and stably putting a sand core of a cast volute part into a mold cavity, and aims to solve the technical problems that in the prior art the core setting process requests great time and labor, the efficiency is low, the quality of a cast product cannot be simultaneously ensured, and the like. The novel core setting tool comprises an elastic positioning plate, wherein the elastic positioning plate is matched with a circular groove above the sand core; a radial opening groove through which a hanging rope for containing and hoisting the sand core penetrates is formed in the elastic positioning plate; the distance between an inner side edge of the radical opening groove and the center of the elastic positioning plate is accordant with the hoisting eccentric distance of the sand core.
