Description

Integrated device for sand falling and sand cleaning for agricultural harvester castings

technical field

The utility model relates to the technical field of casting, in particular to an integrated device for sand falling and sand cleaning for agricultural harvester castings.

Background technique

Sand casting is a casting method for producing castings in sand molds. Steel, iron and most non-ferrous alloy castings can be obtained by sand casting methods. Because the molding materials used in sand casting are cheap and easy to obtain, the casting molds are easy to manufacture. Production, batch production and mass production can be adapted. For a long time, it has been the basic process in foundry production. The outer sand mold used in sand casting is divided into clay green sand mold according to the binder used in the sand and the way to build its strength. , Clay dry sand mold and chemical hardening sand mold 3 types. Shaking and sand cleaning of castings is an important process in the production process of sand mold casting. Shaking is to break the mold after casting and cooling to a certain temperature, so that the mold is separated from the sand box, and the casting is separated from the sand. After sanding, the residual sticky sand on the casting often needs to be cleaned. The process of cleaning the residual sticky sand on the casting is called sand cleaning. After the casting is formed, the casting needs to be sand shaken and sand cleaned. The conventional method is two processes, which are carried out on different equipment, resulting in low processing efficiency.
