Description

Technical Field

[0001] This utility model relates to the field of sand removal for cast iron parts, specifically a vibratory sand removal device for cast iron parts. Background Technology

[0002] Casting is a forming method in which molten metal is poured into a mold of a specific shape and allowed to cool and solidify, resulting in a blank or part with a specific shape, size, and properties. Cast iron parts are an important component of cast products and are widely used in many industries such as machinery manufacturing, automobiles, and construction. Sand removal is one of the key processes in casting production. It is the operation of separating the casting from the mold (sand mold), and its efficiency and quality directly affect subsequent cleaning and machining processes. In cast iron production, once the casting has solidified and cooled to a certain degree, it needs to be removed from the sand mold as soon as possible for the next round of casting production. This also prevents defects caused by uneven cooling due to prolonged exposure to the sand mold. Therefore, a vibrating sand removal device for cast iron parts is needed.

[0003] The existing patent document with technical announcement number CN221890851U provides a casting sand removal machine, which includes a processing chamber, a sealing cover movably installed at the upper end of the processing chamber, a dust suction cover fixedly installed at the top of the sealing cover, a dust collection tank fixedly connected at the lower end of the dust suction cover, and a drawer movably installed inside the dust collection tank. This utility model incorporates a dust removal device for a sand removal machine. The dust removal device is installed at the top of the sand removal machine, and the machine vibrates internally. Impurities generated during vibration are absorbed by a suction pipe at the top. The bottom of the suction pipe is connected to a dust storage tank, inside which a movable processing drawer is installed. A suction pump is installed at one end of the dust storage tank and connected to the processing drawer. Multiple filter plates of different densities are installed inside the drawer, adsorbing impurities of different densities. This multi-layered treatment reduces filter plate clogging. A filter bag is installed at the connection point between the drawer and the suction pump for comprehensive dust removal, reducing the impact of dust generated during processing on the surrounding environment and operators. However, the CN221890851U technology has limitations in terms of rapid sand removal from cast iron parts, effective absorption and dispersion of vibration impact, and rapid collection and flow of sand particles. Therefore, a vibrating sand removal device for cast iron parts is urgently needed. Utility Model Content
