3D printed sand hanging handle suitable for whole process

Abstract

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.

Description

technical field [0001] The invention relates to the field of sand casting, in particular to a hanging handle suitable for 3D printing sand cores (no hanging nose, coreless iron) for coring, transfer, drying, flow coating, core grouping, and core pack transfer. Background technique [0002] 3D printing technology is used in the field of sand casting due to its moldless casting characteristics, and is usually selected to produce multi-variety and small-batch products. Traditional hand-shaped sand cores need to be pre-embedded with core iron and hanging noses in the sand cores. During the transfer process, the hooks are hung on the hanging noses, and the cranes are used for lifting. However, due to the coreless iron and coreless nose of the sand core printed by the 3D printer based on the 3DP forming principle, the sand core needs to be transported frequently in the processes of sand cleaning, flow coating, core grouping, and modeling, so the 3D printing sand core itself needs ...
