Description

Technical Field

[0001] The utility model belongs to the technical field of dust removal in foam mould production, and in particular relates to a mould dust remover for model processing. Background Art

[0002] Lost foam casting (also known as full-mold casting) is a new casting method that uses a foam plastic mold that uses binder-free dry sand combined with vacuum technology. It uses a foam mold that is similar in size and shape to the casting, brushes on a refractory coating and dries it, then buries it in dry quartz sand and vibrates it to shape it. It then pours it under negative pressure to vaporize the model, allowing liquid metal to occupy the model position and form a casting after solidification and cooling.

[0003] A large amount of dust and debris will be generated during the processing, cutting, grinding and forming of foam molds. Generally, a dust collector is used to filter and remove them. The fan is equipped with a filtering device to guide the foam debris into a closed box, and the foam debris in the air entering the box is filtered out. However, due to the large gap between the molecules of the foam, the overall weight is light and fluffy. If it is directly processed without compression, it will occupy ground area during processing, and it also needs to be cleaned repeatedly, which is more troublesome. Therefore, the utility model proposes a foam mold dust collector, which is convenient for removing foam debris and compressing the foam debris for unified processing, thereby reducing the number of cleaning times of the dust collector.

[0004] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content
