[0002] Foundry molding sand, also known as molding sand or casting sand, is raw sand used for manufacturing sand molds and sand cores in casting production, mainly composed of quartz particles with uniform particle size. The molding sand is generally formed by mixing foundry raw sand, molding sand binder and auxiliary materials in a certain proportion, and has good strength, thermal stability, fluidity, plasticity and air permeability. Before casting production, the molding sand feeding device is used to pour the mixed molding sand into the mold, and after the molding sand is shaped and demolded, the casting pouring operation can be performed.

[0003] A molding sand feeding device for casting processing is disclosed in Chinese Patent No. CN218192435U, which comprises a support chassis and a sand feeding hopper.

At least two sand discharging openings are provided through the sand feeding hopper, and a telescopic material guiding device is provided on the outer side of the sand feeding hopper corresponding to each sand discharging opening. A movable sand blocking device is provided on the outer wall of the sand feeding hopper corresponding to each telescopic material guiding device. The driving motor drives the sand discharging scraper to rotate, and the molding sand is sent into the mold through the sand discharging opening and the telescopic material guiding device. After the sand feeding is completed, the movable sand blocking device can be used to block the sand discharging opening. The telescopic material guiding device has adjustable length and can be easily adjusted and used for filling molding sand in various molds. The device can realize automatic sand feeding with high efficiency, reduce the additional consumption of labor, and greatly improve the casting processing efficiency. However, the above-mentioned sand feeding device can only perform sand filling operation of the molding sand, and cannot vibrate the molding sand filled in the mold to fill the gaps of the mold. The above-mentioned sand feeding device has single function and can only be used for sand feeding of the molding sand, and does not have the function of raw sand and raw material stirring, which affects the application range of the device to some extent, thereby affecting the utilization rate of the device. In addition, the above-mentioned sand feeding device is not convenient for workers to know the stock of the molding sand in the sand feeding hopper in real time during use, which causes the interruption of the molding sand feeding due to the inability to timely supplement the molding sand in the sand feeding hopper, affects the continuity of the molding sand feeding, and further affects the efficiency of the casting processing.
