A mold is placed above the vibration table, which is convenient for the sand storage mechanism to inject molding sand into the mold and vibrate the molding sand so that the molding sand fills the gap in the mold, thereby ensuring the quality of the molding sand and sand addition.

[0010] As a further configuration of the above scheme, the transfer mechanism includes a carrying plate and an armrest. The handrail is connected to the side of the carrying plate away from the clamping mechanism to facilitate workers to grasp the mold after sand addition during transportation. A plurality of supporting legs are connected to the bottom of the carrying plate, and a universal brake wheel is connected to the lower end of the supporting leg to facilitate adjustment and fixation of the position of the transfer mechanism. The upper plane of the carrying plate and the upper plane of the vibration table are on the same plane, which facilitates pushing the vibrated mold from the vibration table to the carrying plate, thereby providing convenience for the clamping mechanism to clamp the molding sand.

After the sand replenishment is completed, the first pushing mechanism is used to push it back to the supporting plate, which can further save the workers' effort.

[0013] As a further configuration of the above scheme, the clamping mechanism includes a third telescopic rod and a pressure plate. The telescopic end of the third telescopic rod is connected to the pressure plate, which can compact the vibrated molding sand and further reduce the gaps between the molding sand particles.

[0015] The size and shape of the pressing plate in the molding sand adding device for casting processing are matched with the mold. During use, the corresponding pressing plate is replaced according to different molds to ensure the quality of sand pressing by the pressing plate. Before use, the device injects a sufficient amount of molding sand into the sand storage tank through the first conveyor belt, starts the motor to drive the stirring rod to rotate, and places multiple molds on the second conveyor belt in sequence. The second conveyor belt is started by a controller, and the mold is transported to one side of the limit frame and then closed. The first telescopic rod is controlled by the controller to extend to push the mold close to the limit frame from the second conveyor belt to the vibration table, and the valve is opened to allow the molding sand in the sand storage tank to be injected into the mold through the discharge pipe. During the sand injection process, the vibration table is started to drive the mold to vibrate and vibrate the molding sand in the mold evenly. After the molding sand fills the mold, the valve is closed to stop the discharge pipe from discharging sand, and the vibration table is closed by the controller. The first telescopic rod is controlled by the controller to extend again to push the mold filled with molding sand from the vibration table to the carrying plate through the first push plate. The third telescopic rod is controlled by the controller to extend to allow the third telescopic rod to extend. The three telescopic rods drive the pressing plate to move downward to squeeze the molding sand in the mold, further reducing the gap between the molding sand particles, and then control the third telescopic rod to shrink, separate the pressing plate from the mold, and select whether to use the second pushing mechanism to push the mold from the carrying plate back to the vibration table for secondary sand injection according to the state of the mold sand after compression. If secondary sand injection is required, the first telescopic rod is controlled to shrink and the second telescopic rod is extended, and the second pushing plate is used to push the mold containing the molding sand from the carrying plate back to the vibration table, open the valve to inject an appropriate amount of molding sand into the mold again, close the valve, and use the first pushing mechanism again to push the mold together with the molding sand onto the carrying plate, and use the clamping mechanism for secondary sand pressing.

The transfer mechanism with the mold is transferred to the molding sand storage point, the mold with the molding sand is unloaded from the carrying plate, and the empty transfer mechanism is transferred to one side of the device for standby.

[0016] The present invention has the following beneficial effects in practical application: The use of cameras in the sand storage mechanism helps workers to understand in real time the amount of molding sand in the sand storage tank and the operation of the sand storage tank itself and the stirring rod, so as to replenish molding sand into the sand storage tank in time and ensure the continuity of the molding sand adding operation. When the stirring rod fails or the discharge pipe of the sand storage tank is blocked, the workers can shut down the device in time, resume the operation of the device after troubleshooting, and ensure the efficiency of the molding sand adding of the device.

[0017] The combination of the sand storage tank, the stirring rod and the motor can not only store the molding sand and break up the molding sand in the sand storage tank to facilitate the discharge of the molding sand from the discharge pipe, but also be used for mixing the molding sand raw materials, thereby enriching the applicable scenarios of the device and improving the utilization rate of the device.

[0018] The combined use of two pushing mechanisms makes it easy to change the position of the mold during the sand adding process, saving the workers' effort in carrying the mold. The use of the vibration table can vibrate the molding sand injected into the mold evenly so that the molding sand fills the gaps in the mold. The use of the compacting mechanism can compact the molding sand in the mold, further reducing the gaps between the molding sand particles and ensuring the quality of sand adding.

During the sand injection process, start the vibration table 3, so that the vibration table 3 drives the mold 4 and the molding sand in the mold 4 to vibrate, and vibrate the molding sand in the mold 4. After the molding sand fills the mold 4, close the valve 1111 to stop the discharge of sand from the discharge pipe 111. , use the controller 7 to turn off the vibration table 3, use the controller 7 again to control the first telescopic rod 82 to extend and push the mold 4 filled with molding sand from the vibration table 3 to the supporting plate 61 through the first push plate 83, use the controller 7 to control the extension of the first telescopic rod 82 and the second telescopic rod 92 to adjust the position of the mold 4 on the supporting plate 61, so that the mold 4 is aligned with the pressing plate 102, and then use the controller 7 to control the first telescopic rod 82 to shrink and reset, use the controller 7 to control the third telescopic rod 101 to extend, so that the third telescopic rod 101 drives the pressing plate 102 to move downward to extrude the molding sand in the mold 4, so as to further reduce the gap between the molding sand particles, and after the extrusion is completed, control the third telescopic rod 101 to shrink and separate the pressing plate 102 from the mold 4.

[0036] Determine whether the state of the mold sand after compaction meets the casting requirements of the casting, so as to determine whether it is necessary to use the second pushing mechanism 9 to push the mold 4 from the carrying plate 61 back to the vibration table 3 for secondary sand injection. If the casting requirements of the casting are met, no secondary sand injection is required. Open the brake of the universal brake wheel 64, hold the handrail 62 to move the transfer mechanism 6 together with the mold 4 filled with mold sand from the bottom of the clamping mechanism 10, move another empty transfer mechanism 6 to the bottom of the clamping mechanism 10, step on the brake of the universal brake wheel 64 to fix it, transfer the mold 4 to the molding sand storage point, remove the mold 4 from the carrying plate 61, and move the empty transfer mechanism 6 to one side of the clamping mechanism 10 for standby use.

[0037] If the casting requirement is not met, secondary sand injection is required. At this time, the controller 7 is used to control the second telescopic rod 92 to extend so that the push plate moves toward the mold 4 on the supporting plate 61, and the second push plate 93 is used to push the mold 4 filled with molding sand from the supporting plate 61 back to the vibration table 3. The controller 7 is used to control the second telescopic rod 92 to shrink and reset, and the valve 1111 is opened to inject an appropriate amount of molding sand into the mold 4 again. After that, the valve 1111 is closed, and the controller 7 is used again to control the first telescopic rod 82 to extend so that the first push plate 83 pushes the mold 4 together with the molding sand onto the supporting plate 61. The clamping mechanism 10 is used again for secondary sand pressing. After the sand pressing is completed, the transfer mechanism 6 can be used to transfer the mold 4 and an empty transfer mechanism 6 can be placed under the clamping mechanism 10. The controller 7 is used to start the second conveyor belt 51 again, and another mold 4 is conveyed to one side of the limit frame 52, and then the second conveyor belt 51 is closed. Then, the above operation is repeated to complete the sand adding operation for the remaining molds 4.

[0038] During the sand adding process, the worker transmits the food image back to the terminal device through the camera 14, and grasps the inventory of the molding sand in the sand storage tank 11 and the operation of the stirring rod 12 in real time. When the inventory is small, the molding sand is promptly added to the sand storage tank 11 through the first conveyor belt 22. When the stirring rod 12 fails, the valve 1111 and the motor 13 are promptly closed, and the stirring rod 12 is repaired. After the failure of the stirring rod 12 is eliminated, the motor 13 is promptly started to drive the stirring rod 12 to run, so as to ensure the continuity of the molding sand addition.
