Description

Technical Field

[0001] The utility model relates to the technical field of auxiliary frame processing, in particular to a sand dumping mechanism for a large-scale auxiliary frame low-pressure product. Background Art

[0002] At present, subframes are all formed by one-piece low-pressure casting. The product has a large ratio and is a hollow structure. During molding, a sand core is used inside the molding and the sand core is shaken out. Due to the complex internal structure of the subframe, there may be residues from the shaking and shaking sand. After heat treatment, the fine sand is then put into the inner cavity of the subframe. Due to the high safety requirements for the subframe, fluorescent flaw detection is required. If the sand is not poured out cleanly, it will affect the fluorescent liquid. The manual sand pouring is relatively strong, the product is relatively heavy, and the pouring time is relatively long, which is inefficient. Utility Model Content
