Technical Field

[0001] The utility model belongs to the technical field of casting wellhead fixing piles, in particular to an adjustable fixing pile for a deep well casting wellhead. Background Art

[0002] Deep well casting is a high-end casting process. It is a method in which liquid metal is filled into a casting mold under air pressure in a casing that carries heavy objects, and then uniformly cooled and solidified by constant pressure and temperature to obtain precision castings. After the mold plate is replaced, an anti-falling frame will be set at the wellhead of deep well casting. The anti-falling frame of the wellhead of deep well casting is fixed by four fixed piles set at the wellhead.

[0003] The four fixing piles of the existing deep well casting wellhead are directly fixed around the wellhead by welding. Every time the mold plate wellhead anti-falling frame is replaced, scratches will occur due to the mismatch of the fixed pile positions. There is a 20cm-45cm mark on the entire furnace when the machine is started during production, and there is a risk of personnel falling or the entire furnace of finished products being dumped due to the displacement and misalignment of the anti-falling frame at the end of casting. Therefore, hot work is required when actually adjusting and replacing the mold plate, which delays the production order and increases the labor efficiency and risk of hot work. For this reason, the utility model proposes adjustable fixing piles for deep well casting wellheads. Utility Model Content
