A transmission member 4 is rotatably connected to the sand shooting pot body 2. A sand loosening member 5 is fixedly connected to the transmission member 4. The sand loosening member 5 is rotatably connected in the sand shooting pot body 2. The transmission member 4 is connected to a driving pressurizing member 6. The driving pressurizing member 6 is connected to the sand shooting pot body 2. The device is electrically connected to an external control device through a conductive line, and the operating state of the device is controlled by the external control device. The sand shooting pot body 2 is installed on the molding machine body 1. When adding sand to the sand box on the molding machine body 1, the molding sand is added to the storage bucket 301, and the molding sand is controlled by the gate 302 to fall into the conical tank 201. After the gate 302 is closed, the interior of the conical tank 201 is in a sealed state, and the air will not leak from the storage bucket 301. After the molding sand falls into the conical tank 201, the cylinder 605 is extended to move the fixed frame 601 upward, and the threaded column 602 fixedly connected to the fixed frame 601 is raised. Since the threaded column 602 is threadedly connected to the threaded hole 403, the guide rod 604 fixedly connected to the fixed frame 601 is slidably inserted into the insertion hole at the top of the cylinder 202, so as to limit the vertical lifting of the fixed frame 601, and the air pressure cylinder 401 is rotatably connected to the cylinder 202, so When the threaded column 602 rises, the threaded column 602 maintains vertical lifting and does not rotate, the threaded hole 403 threadedly connected to the threaded column 602 will rotate along the thread line, and the transmission member 4 will rotate in the cylinder 202. Since the sand loosening member 5 is fixedly connected to the cross block 405, when the transmission member 4 rotates, the sand loosening member 5 will rotate inside the conical tank 201. Through the design of the stirring blade 502, the molding sand inside the conical tank 201 can be stirred, so that the molding sand that is agglomerated due to heat or moisture can be loosened and the uniformity of sand addition in the later stage is improved. When the threaded column 602 rises, the sealing plug 603 slides and rises in the air pressure cylinder 401. The second one-way valve 606 provided on the sealing plug 603 is kept when the sealing plug 603 rises. The first one-way valve 404 arranged on the boss 402 remains closed when the sealing plug 603 rises, and remains open when the sealing plug 603 is pressed down, so that when the sealing plug 603 is raised and lowered in the air pressure cylinder 401, the interior of the conical tank 201 is pressurized to realize the filling and use of molding sand, so that the molding sand inside the conical tank 201 can be filled into the sand box as the pressure is increased, and the molding sand can be pre-compacted inside the sand box under a high-pressure environment, and the stirring blade 502 is designed to rotate inside the conical tank 201 to scrape off the molding sand on the inner wall of the conical tank 201, so that the inner wall of the conical tank 201 will not have residual molding sand when adding sand, which can avoid the residual molding sand on the inner wall of the conical tank 201.This results in insufficient sand addition to the sand box, affecting the molding quality of the product.
