Casting shakeout machine

Abstract

The invention discloses a casting shakeout machine in the field of casting. The casting shakeout machine comprises a rack, a shakeout device, a molding sand collection device and a noise reduction and dedusting device, wherein the shakeout device is arranged at the upper part of the rack, and comprises an impact hammer and a vibration seat; the molding sand collection device is positioned below the vibration seat, and comprises a molding sand collection box; the noise reduction and dedusting device comprises a sound absorbing layer, a suction fan and a filter box; the sound absorbing layer is positioned on the inner wall of the rack; the filter box is positioned on the outer side of the rack; a plurality of layers of filter screens are arranged in the filter box; an exhaust fan is arranged on the outer side of the filter box; the bottom of the filter box is inclined andcommunicateswith the molding sand collection box; an air collecting hood is arranged at the top end of the rack; the suction fan is mounted on the air collecting hood; and an air suction pipe connected with the filter box communicates with the suction fan. According to the scheme, high-temperature sandy dust airflow arisingby shakeout is prevented from polluting the environment and harming the human bodies, the working environment is improved and is more environment-friendly and safer, the molding sand waste is avoided, the utilization rate of the molding sand is increased, and the cost is reduced.

Description

technical field [0001] The invention relates to the field of casting, in particular to a casting shakeout machine. Background technique [0002] Castings after pouring and cooling must be shaken out and cleaned before they can be machined or used. Shaking sand refers to the process of separating castings, molding sand and sand boxes by hand or machinery after sand casting. Generally, the method of shakeout in factories is carried out on a vibrating shakeout machine, which uses the collision between the mold and the shakeout machine to achieve shakeout. [0003] When the vibration shakes out, a large amount of sand and dust will be raised in the workshop. These sand and dust will not only affect the working environment and pollute the air in the workshop, but may also cause workers to suffer from lung disease. Therefore, sand and dust must be disposed of in time. [0004] Generally, the sand-out temperature of iron castings is between 400 and 500 °C, and the iron castings ...

Problems solved by technology

That is to say, the sand dust produced by falling sand not only has many particles but also has a high temperature. Working in such an environment will greatly increase the labor intensity of workers and cause greater damage to workers' health.
