[0001] The utility model belongs to the field of air blowing of core shooters, and particularly relates to an air blowing mechanism of a core shooter. Background Technique

[0002] At present, core shooters have been widely used in the automated production of casting sand cores. The sand cores manufactured by core shooters have high dimensional accuracy, good surface quality, and high production efficiency. After the sand core is formed, an air blowing structure is needed to blow away the impurities in the mold groove to ensure the forming quality of the sand core. However, in the current use of air guns, the pipelines are often dragged on the ground randomly. After long-term use, the pipelines will be worn, and the workshop will be messy, posing a safety hazard of tripping for the staff. Content of the Utility Model

[0003] The purpose of the utility model is to provide an air blowing mechanism of a core shooter, which has the advantages of realizing the storage and use of pipelines, reducing the wear caused by dragging the pipelines on the ground, avoiding the risk of tripping for the staff caused by the pipelines scattered on the ground, improving the use convenience of the air gun, and having flexibility, so that the operation process can be more comfortable and natural.

[0004] The above technical purpose of the utility model is achieved by the following technical solutions: an air blowing mechanism of a core shooter, including a first plate body and a second plate body, a rod body is rotatably connected between the first plate body and the second plate body, a pipeline penetrating to one side of the first plate body is arranged inside the rod body, one end of the pipeline is communicated with a rotary joint, the other end of the rod body penetrates into the second plate body and is fixedly sleeved with a first gear, a second gear is meshed on the surface of the first gear, the pipeline is wound around the surface of the rod body and is communicated with an air gun, a placing member for cooperating with the air gun is arranged on one side of the first plate body, a slider is arranged on one side of the placing member, a bolt penetrating to the other side of the first plate body is fixedly installed on one side of the slider, and a knob is threadedly connected to the surface of the bolt.
