A detachable sand box for sand casting

Abstract

The invention relates to a detachable sand box for sand casting, which includes a bottom plate, front and rear side plates, left and right side plates and a cleaning unit. There are left and right side plates, and the front and rear side plates and the outer ends of the left and right side plates are equipped with cleaning units; the invention adopts the design of opening and closing the sand box, so that after the casting is completed, the casting can be taken out directly by opening the sand box without It is necessary to turn over the heavy sand box for blanking, so that the blanking of castings can be completed manually without mechanical assistance; at the same time, the invention completes the closing of the detachable sand box through the setting of the clamping and locking mechanism. When the sealing treatment, at the same time through the adjustable cleaning brush, without affecting the internal space, the inner surface of the sand box after blanking 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
