[0002] Coated sand. The surface of the sand is covered with a layer of solid resin film before molding. There are two coating processes: cold method and hot method. The cold method is to dissolve the resin with ethanol and add urotropine during the sand mixing process, so that the two are coated on the surface of the sand. The ethanol evaporates to obtain coated sand. The hot method is to preheat the sand to a certain temperature, add resin to melt it, stir to coat the resin on the surface of the sand, add urotropine aqueous solution and lubricant, cool, crush and screen to obtain coated sand. It is used for casting steel and iron parts. Coated sand mainly uses high-quality selected natural quartz sand as raw sand, thermoplastic phenolic resin, urotropine and reinforcing agent as raw materials.

[0024] In a preferred embodiment, one end of the extrusion rod 10 passes through the interior of the trough body 4 and the extrusion rod 10 is slidably connected to the collection box body 3. The end of the extrusion rod 10 away from the movable plate 7 is fixedly connected to a movable plate 11. A sliding groove 12 is provided on the outer wall of the movable plate 11. When the movable plate 11 moves, the movable plate 11 will drive the extrusion rod 10 to move, so that the extrusion rod 10 can drive the movable plate 7 to move.
[0025] In a preferred embodiment, a slider 13 is slidably connected inside the slide groove 12, a rotating plate 14 is fixedly connected to the outer wall of the slider 13, a driving shaft 15 is fixedly connected to the outer wall of the rotating plate 14, one end of the driving shaft 15 passes through the outer wall of the collection box 3 and the driving shaft 15 is rotatably connected to the collection box 3, a motor 16 is fixedly connected to the outer wall of the collection box 3, one end of the output shaft of the motor 16 is fixedly connected to the driving shaft 15, when the driving shaft 15 moves, the driving shaft 15 can drive the rotating plate 14 to move, so that the rotating plate 14 can drive the slider 13 to move.

When the gas enters the first through pipe 8, the gas can pass through the No. 1 one-way valve 18 inside the first through pipe 8, so that the movement trajectory of the gas is restricted.
[0027] The working principle of the utility model is as follows: when the device is used, the box in the automatic spraying equipment 2 is opened, and the motor 16 is started at this time, so that the output shaft of the motor 16 drives the driving shaft 15 to move, so that the driving shaft 15 rotates inside the slot 4, and the driving shaft 15 drives the rotating plate 14 to move, so that the rotating plate 14 moves in a circular motion inside the slot 4, and the rotating plate 14 drives the slider 13 to move at the same time, so that the slider 13 moves in a circular motion inside the slot 4, and the slider 13 can slide inside the slide groove 12, so that the rotating plate 14 can drive the moving plate 11 to move through the slider 13 and the slide groove 12, so that the moving plate 11 slides inside the slot 4, and the moving plate 11 drives the extrusion rod 10 to move, so that the extrusion rod 10 slides inside the slot 4 and the connecting slot 5. The movable plate 7 moves. When the movable plate 7 moves toward the direction of the tank body 4, the gas can enter the connecting tank 5 from the first through pipe 8 through the No. 1 one-way valve 18.

[0029] In a preferred embodiment, one end of the pull rod 23 is slidably connected to the positioning groove 21, and a slide plate 24 is fixedly connected to the outer wall of the pull rod 23, and a spring 25 is fixedly connected to the outer wall of the slide plate 24.
