The invention relates to the field of sand mold casting, in particular to a hanging handle suitable for a 3D printed sand core. The hanging handle comprises hanging piles, anti-slip pieces and fixture holes, wherein the hanging piles are connected with a sand core body, and the section of each hanging pile is in the shape of an arc; the sand core body is divided into an upper sand core and a lower sand core; the anti-slip pieces with the outer diameter larger than that of the hanging piles are connected with the hanging piles; concave parts with an arc angle are formed at the positions of inner side joints; protruding parts higher than the hanging piles are arranged on the outer sides and used for preventing the situation that in the hanging and transporting process of the sand core, a hanging band slides and falls off, and danger is caused; the fixture holes are formed in the outer side faces of the anti-slip pieces; hanging handle bodies are arranged on the two sides of the gravity center axis of the sand core body; and the center lines of the hanging handle bodies on the two sides are coaxial. The device is simple in structure, convenient to use, capable of taking achievement of 3D printing, core taking, transferring, pre-surface-drying, sand removing, flow coating, drying, core assembling, core packet transferring, modeling, backing sand filling and other procedures into consideration, and high in functionality.
