[0002] A molding machine is a foundry device used to create sand molds. Its main functions are: filling the sand flask with loose sand; and compacting the sand flask through various methods, such as vibration, compaction, shock compression, and injection. Injection molding machines use compressed air to evenly inject sand into the flask for pre-compaction, and then apply pressure for compaction.

[0003] A sand shooting box mechanism for a molding machine is disclosed in announcement number CN219074305U. Although the device can seal the delivery pipe through a movable airtight structure, the high-pressure gas can build up pressure after entering the sand shooting box, and the molding sand entering the sand shooting box can be transported to the mold cavity through high pressure, thereby improving the utilization rate of the high-pressure gas.

[0004] However, the sand shooting box mechanism used in the molding machine has the following disadvantages: it is not convenient to screen the larger particles in the sand material, and casting with large particles of sand material will affect the quality of the sand mold; it is also not convenient to quantitatively shoot the sand material, which easily causes sand material waste and increases recovery pressure.
