Description

Technical Field

[0001] The utility model relates to the technical field of core shooting machines, in particular to a three-way adjustment mechanism of a sand shooting head. Background Art

[0002] The core shooter plays a key role in casting production. It uses high-pressure air or mechanical force to shoot sand into the core box to form sand cores for casting. As one of the core components of the core shooter, the accuracy of the position of the sand shooter directly affects the quality and production efficiency of the sand core. Traditional core shooter sand shooters are often fixed or can only be adjusted manually, which limits their applicability and flexibility when handling complex molds.

[0006] Furthermore, a fixing plate is provided on the outer ring of the fixing screw sleeve, and a plurality of mounting holes are distributed around the outer ring of the fixing plate.

[0007] Furthermore, one end of the screw rod is rotatably connected to the adjustment plate via a bearing.

[0008] Furthermore, the driving device is a pneumatic cylinder or an oil cylinder.
