Dust removal mechanism for sand box for lost foam casting

Abstract

The invention provides a dust removal mechanism for a sand box for lost foam casting, and relates to the technical field of dust removal equipment. The mechanism includes a base, a supporting column and a fixing frame, the supporting column is arranged on one side of the upper surface of the base, and a dedusting mechanism is arranged on one side of the supporting column; the fixing frame is arranged in the middle of the upper end of the base, and a first motor is installed on one side of the top end of the fixing frame; and the output end of the first motor passes through the top of the fixing frame to extend to the interior of the fixing frame and is fixedly connected to a screw rod, and a screw sleeve sleeves the screw rod, and the inner wall of one side, close to the screw rod, of thefixing frame is provided with a slide groove. The mechanism has a simple structure, the dedusting mechanism, a collection box, a dust collection pipe, a fan and a dust suction hood are arranged and used in a cooperation manner, so that the impact of dust on human health is reduced, and the processing accuracy of the sand box is improved; and when the mechanism is used, the fan is started to work,through the fan, dust and debris generated when cutting is performed on a worktable enter the dust collection pipe through the dust suction hood, and then the dust and debris enter the collection boxto complete dust collection to avoid polluting the environment.

Description

technical field [0001] The invention relates to the technical field of dust removal equipment, in particular to a sand box dust removal mechanism for lost foam casting. Background technique [0002] Lost foam casting (also known as solid mold casting) is a solid mold casting in which foam plastic molds are combined with dry sand without binders and vacuum pumping technology. It is to bond and combine foam models similar in size and shape to the castings to form a model cluster, and brush refractory coatings. After being dried, it is buried in dry quartz sand for vibration molding, poured under negative pressure to vaporize the model, liquid metal occupies the position of the model, solidifies and cools to form a new casting method. [0003] The current lost foam casting sandbox is easy to generate a lot of waste and dust during manufacture, which makes the dust waste fly around, and the dust inhalation is not conducive to human health. At the same time, when the sandbox is...

Problems solved by technology

[0003] The current lost foam casting sandbox is easy to generate a lot of waste and dust during manufacture, which makes the dust waste fly around, and the dust inhalation is not conducive to human health. At the same time, when the sandbox is processed and cut, it cannot be fixed well, affecting Cutting efficiency and quality
