Abstract

The invention relates to the technical field of production and machining of castings and discloses a sand removing device of a casting. The sand removing device comprises a groove with an opening formed in the upper portion. Sand removing balls are arranged in the groove. Vertical springs are connected between the sand removing balls and the groove. The sand removing balls are connected with a sand removing mechanism. A rotating wheel and a connecting plate are arranged above the groove, the rotating wheel is fixedly connected with a pushing handle, a straight slide groove is formed in the connecting plate, and the pushing handle is arranged in the slide groove in a sliding mode. A hanging rod is fixedly connected to the connecting plate and rotationally connected with a fan wheel. A magnetic attraction fixing portion is arranged at the bottom of the fan wheel. An air blower is further arranged on the outer side of the groove and comprises a shell and a fan arranged in the shell. The fan is fixedly connected with a rotary shaft. The rotary shaft and the rotating wheel are connected through a belt. The shell is connected with an air blowing pipe, and the free end of the air blowingpipe is connected to the side wall of the groove and communicates with the interior of the groove. Through the sand removing device of the casting, the casting can be prevented from being collided ordamaged in the sand removing process, and the casting production and machining quality is improved.

Description

technical field [0001] The invention relates to the technical field of production and processing of castings, in particular to a sand cleaning device for castings. Background technique [0002] Castings are metal shaped objects obtained by various casting methods, that is, the smelted liquid metal is poured into the pre-prepared mold by pouring, injection, suction or other casting methods, and after cooling, it is polished and other subsequent processing methods , the resulting object has a certain shape, size and performance. [0003] Sand casting is a traditional casting process that uses sand as the main molding material to make molds. Part of the molding sand will remain on the casting after sand casting, so it is necessary to clean the casting to ensure the production and processing quality of the casting. The sand cleaning device of existing castings is usually a vibrating structure, and the sand cleaning device usually includes a processing cylinder, which is connec...
