Automatic casting cavity sweeping machine

Abstract

The invention discloses an automatic casting cavity sweeping machine, wherein a casting cavity comprises an upper box (7) and a lower box (10); the automatic sweeping machine is provided with a rack, a lifting system, a sweeping system and a control system; the sweeping system is provided with a hollow tubular sweeping arm (8) capable of doing rotary motion; a plurality of blowing nozzles (9) are arranged on the sweeping arm (8); the sweeping arm (8) is connected with an air supply pipeline (19) for air compression. With adoption of the technical scheme, automatic sweeping and cleaning of loose sand or fine sand attached to the surface of the casting cavity are realized, the degree of automation is high, the manual work is replaced, the labor force is liberated, and the production efficiency is improved; the loose sand or fine sand is cleaned thoroughly and the effect is obvious; durability and stability are realized, the internal quality of a casting product is improved, and the production cost is reduced; the automatic casting cavity sweeping machine is widely applicable to sweeping before sand mould modeling casting, metal mold heat preservation area redundant sand modeling casting, iron mould covered sand modeling casting and the like.

Description

technical field [0001] The invention belongs to the technical field of thermal processing of metal materials, and relates to auxiliary process technical equipment before casting and pouring. Specifically, the invention relates to an automatic purging process technology before casting and pouring. Background technique [0002] At present, in the foundry industry, loose sand or dust will inevitably adhere to the surface of the cavity after molding. If it is not removed in time, these loose sand or dust will be integrated into the casting body after pouring, causing fatal defects inside the casting and affecting the internal quality of the casting. . [0003] The traditional way to clean up the loose sand or dust left over from the modeling is: when the workers are modeling, blow with their mouth; or use a brush to remove; or use a leather tiger to blow. These methods can only clean up loose sand or dust to a certain extent, but cannot completely remove it. [0004] There is...

Problems solved by technology

[0005] However, the above-mentioned methods all require human operation and manual cleaning, and there are inevitably omissions; manual work also has fatigue phenomena, and it is easier to damage the casting cavity when encountering large parts, which cannot guarantee the stability and effectiveness of the work for a long time, and also affects the product quality. Bringing hidden dangers; simple mechanical devices combined with manual work, there is a hidden danger of equipment injury
