Sand casting detachable sand box

Abstract

The invention relates to a sand casting detachable sand box which comprises a base plate, a front side plate, a back side plate, a left side plate, a right side plate and cleaning units. The front andback ends of the base plate are connected with the front side plate and the back side plate in a hinged mode, the left and right ends of the base plate are connected with the left side plate and theright side plate in a hinged mode, and the cleaning units are installed at the outer ends of the left and right side plates and the front and back side plates. Due to the openable design of the sand box, after casting is completed, casting parts can be directly taken out by opening the sand box, discharging can be performed with no need of turning over the heavy sand box, the casting parts can bedischarged through manual work, and no mechanical assistance is needed; meanwhile, by arranging a clamping and locking mechanism, sealing treatment needed when the detachable sand box is closed is completed, and meanwhile, due to adjustable cleaning brushes, the inner surface of the sand box obtained after discharging can be cleaned.

Description

technical field [0001] The invention relates to the technical field of casting processing, in particular to a detachable sand box for sand casting. Background technique [0002] Sand casting refers to the casting method that produces castings in sand molds. Steel and most non-ferrous alloy castings can be obtained by sand casting. Because the molding materials used in sand casting are cheap and easy to obtain, and the casting mold is easy to manufacture, it can be adapted to single-piece production, batch production and mass production of castings. It has been the basic process in casting production for a long time. Compared with other casting methods, sand casting has low cost, simple production process and short production cycle. Therefore, it is more and more widely used in the foundry industry. In the future, it will play an increasingly important role in the foundry industry. [0003] Sand casting requires the use of sand boxes, but the existing sand boxes are often...

Problems solved by technology

[0003] Sand casting requires the use of sand boxes, but the existing sand boxes are often directly welded, so that the sand box needs to be turned over with mechanical assistance after each casting, which increases the cost of the enterprise. In the production of a single large casting In the process, the machinery for blanking is redundant and wasteful, so a sandbox that can be manually blanked is needed
