Iron mold sand coating production line and production method thereof

Abstract

An iron mold sand coating production line comprises a casting section, a lower mold section, a mold closing section, a sand washing section, a piece discharging section and a sand clearing section. The casting section, the lower mold section and the mold closing section are serially connected through an annular conveying line, the annular conveying line form a shape of a football field in a surrounding mode, and a moving trolley is arranged on the annular conveying line. The sand washing section and the sand clearing section are serially connected through a first linear conveying line, and the first linear conveying line is parallel to the straight line portion of the annular conveying line. A second linear conveying line is parallelly arranged on the side of the first linear conveying line, and the first linear conveying line is arranged between the annular conveying line and the second linear conveying line. The sand washing section and the mold closing section are communicated through third linear conveying lines, and the third linear conveying lines are arranged in a paired mode. By adopting the technical scheme, casting of multiple products can be achieved simultaneously, and occupied space and device cost are saved.

Description

technical field [0001] The invention relates to the field of iron mold sand-coated casting, in particular to an iron mold sand-coated production line and a production method thereof. Background technique [0002] The sand-coating process of iron mold is a process of producing castings by using a casting mold formed by casting a roughly formed iron mold inner cavity (core iron) surface with a thin layer of resin sand lining. The main advantage of this process is that the surface of the iron mold is covered with a layer of resin sand lining, the working conditions during pouring are greatly improved, and it can effectively withstand the thermal shock of high-temperature molten iron. The maximum temperature in the mold can be increased by 600%. When it is lowered to about 200°C, the temperature gradient in the thickness direction of the iron mold is also greatly reduced, and the thermal stress of the iron mold is significantly reduced, which is very beneficial to improving the ...

AI Technical Summary

Problems solved by technology

[0004] Iron mold sand-covered casting has been gradually realized and replaced manual labor, but the existing production lines control the corresponding equipment to achieve production after the sand box reaches the corresponding station, and the existing automation equipment only plays the role of assisting workers. For example: when unpacking, workers are required to take out the castings; when the existing production line is in production, at least one worker is required for each process, and the time for each worker to complete each process is uncontrollable, resulting in low production efficiency. Low

[0005] There is another problem in the existing iron sand-covered casting production line: each production line can only produce one product at a time, and when it is necessary to produce another product model, the original sand box and mold must be replaced before another product can be produced When a new model is produced, the original model will stop production. Therefore, according to the current production line, if an enterprise wants to produce two or more products at the same time, it needs to build multiple corresponding production lines. On the one hand, the cost of factory buildings and production lines is high. On the other hand, the cost of manpower is also high
