Description

Technical Field

[0001] The utility model relates to the technical field of casting equipment, in particular to a filter screen regulating mechanism for a cylinder head casting mould. Background Art

[0002] At present, most of the cylinder heads are formed by aluminum alloy gravity casting. During gravity casting, aluminum liquid is refined and slag removal is impossible to be completely clean, including slag attached to the furnace arm. Since the cylinder head engine is the heart of the car, the requirements are relatively high, and the shape of the cylinder head is complex. During casting, the slag in the aluminum liquid may remain in the cylinder head body along with the structure of the cylinder head, causing the cylinder head to leak and be scrapped, and may even cause the sold cars to be recalled, resulting in relatively large economic losses.
