Description

Technical Field

[0001] The invention relates to the technical field of sand cleaning machines, in particular to a silica sol precision casting vibration shell sand cleaning machine. Background Art

[0002] The silica sol precision casting vibration shell sand cleaning machine is a key equipment used in the precision casting industry to clean the surface sand of castings. This equipment mainly uses the exciting force generated by the vibration motor, which will generate a periodic force to vibrate the workbench where the casting is placed, so that the sand on the surface of the casting can be effectively separated from the casting under the action of vibration.

[0003] When the existing sand cleaning machines are in use, since most of them only use vibration components to vibrate and clean the castings, and due to the complexity of the casting shape and the unevenness of the mold shell, the sand cleaning machine may not completely clean the sand locally during the process of vibrating the shell to clean the sand. As a result, after the castings are processed by the sand cleaning machine, workers still need to clean the castings a second time, which makes the sand cleaning effect of the sand cleaning machine poor, thereby increasing the workload of the workers.

[0004] Combining the above problems, we will find that it is difficult to avoid the above problems at the same time when using the existing silica sol precision casting vibration shell sand cleaning machine on the market, and even if it can be solved, it needs to be solved through external tools, which cannot achieve the desired effect.

The four telescopic rods 317 are respectively located inside the four connecting springs 309. The telescopic end of each telescopic rod 317 is fixedly connected to the bottom surface of the impact plate 310. The installation of the telescopic rods 317 serves to limit the moving trajectory of the impact plate 310, thereby preventing the impact plate 310 from deviating from the moving trajectory during movement, thereby ensuring the stability of the movement of the impact plate 310.

[0054] The specific implementation of this embodiment is as follows: when the mechanical claw 18 drives the casting to move to the top of the placement box 301, the operation of the rotating motor 16 is stopped, and then the casting is placed inside the placement box 301 by using the mechanical claw 18, and the ultrasonic generator 302 is turned on at the same time, and the ultrasonic generator 302 is used to generate ultrasonic waves, and at the same time cooperates with the sodium hydroxide solution inside the placement box 301, so that the residual molding sand on the casting falls off and dissolves. After the falling off and dissolution are completed, the casting is taken out by the mechanical claw 18, and is moved to the side close to the processing box 2101. During the movement, The power provided by the second water pump 303 is used to extract the solution inside the placement box 301 into the filter box 305, and the filter screen 307 is used to filter the solution to separate the molding sand. During the filtration, the water flows onto the impact plate 310, so that the impact plate 310 compresses the connecting spring 309, and the impact plate 310 triggers the touch switch 311, so that the touch switch 311 opens the flow valve 314, so that a certain amount of sodium hydroxide solution is added to the interior of the placement box 301, thereby ensuring the subsequent treatment of residual molding sand.
