The water tank 521 is bidirectionally connected to the bag filter 522 and the oil-water separator 523.

[0042] The process of using this utility model:

[0043] The mold is placed on the hydraulic lifting platform 22 and lifted until the conveyor roller 1 23 is level with the transition roller 34, the conveyor roller 2 325 and the conveyor roller 3 45. The laser sensor 6 can detect the accurate position of the mold on the ultrasonic cleaning equipment. Based on the precise positioning of the mold, the operation of each part of the ultrasonic cleaning equipment is automatically or manually controlled. The drive motor 1 21 drives the conveyor roller 1 12 and the drive motor 3 3232 drives the conveyor roller 2 325 to send the mold into the suspension 324 of the lifting mechanism 32.

[0044] After the mold enters the suspension 324, the output end of the drive motor 3232 disengages from the conveyor roller 325. The lifting motor 321 drives the screw jack 322, which in turn drives the suspension 324 to sink. The mold is then immersed in the cleaning tank 31 along with the suspension 324. The cleaning liquid in the cleaning tank 31 is heated by the heating pool 511. At the same time, the mold is cleaned by the ultrasonic vibration plates 33 set on the side wall and bottom of the cleaning tank 31. After cleaning, the lifting motor 321 lifts the suspension 324 and the mold out of the cleaning tank 31 through the screw jack 322. The output end of the drive motor 3232 is then connected to the conveyor roller 325. The drive motor 3232 drives the conveyor roller 325 to send the mold from the conveyor roller 325 to the conveyor roller 45. The conveyor roller 45, driven by the drive motor 42, sends the mold between the nozzle frames 441.

[0045] The nozzle frame 441 is slidably set, and a rack 442 is set on the top of the nozzle frame 441. The drive motor 431 drives the drive gear 433 to rotate through the chain. The drive gear 433 drives the rotating shaft 432 and the driven gear 434 to rotate. The driven gear 434 meshes with the rack 442 and drives the rack 442 to move, thereby driving the nozzle frame 441 to slide. The suction pump draws the cleaning fluid from the water tank 521 and sends it to the nozzle frame 441 through the pipeline and sprays it out from the nozzle 443, thereby thoroughly cleaning the mold.

[0046] When the suspension 324 moves up and down, the pneumatic clutch assembly 323 disengages from the second conveyor roller 325. When it is necessary to drive the second conveyor roller 325 to convey the mold, it engages with the second conveyor roller 325. The cylinder 3231 pushes the sliding frame 3234 to slide back and forth on the mounting frame 3233. The third drive motor 3232 is mounted on the sliding frame 3234 and moves back and forth with the sliding frame 3234. When the third drive motor 3232 moves back and forth, the output end of the third drive motor 3232 can disengage and engage with the second conveyor roller 325. The output end of the third drive motor 3232 is provided with a protrusion. The end of the second conveyor roller 325 is provided with a groove that mates with the protrusion. The protrusion has an arc-shaped chamfer, which can help the protrusion to be quickly and accurately inserted into the groove, thereby realizing the rapid engagement of the third drive motor 3232 and the second conveyor roller 325.

[0047] Several sliding isolation doors 7 are provided between the loading and unloading mechanism 2, the cleaning mechanism 3 and the purging mechanism 4. When ultrasonic cleaning and purging cleaning are performed, the isolation doors 7 are lowered to close and isolate the water mist to prevent the water mist from escaping. A demister 37 is provided on the top of the cleaning mechanism 3 to treat the water mist that escapes from the cleaning tank 31 due to high temperature and ultrasonic vibration.

[0048] The cleaning fluid used by the cleaning mechanism 3 and the purging mechanism 4 is treated by the ultrasonic cleaning fluid treatment mechanism 51 and the purging cleaning fluid treatment mechanism 52 respectively. The oil-water separator 1 512 and the oil-water separator 2 523 can be used to remove surface oil from the cleaning fluid. The filter frame, filter screen and bag filter 522 can be used to remove particulate matter in the cleaning fluid. The treated cleaning fluid is recycled.

[0049] Unless otherwise specified or further limited to one preferred or alternative technical means being another, the preferred and alternative technical means disclosed in this utility model can be arbitrarily combined to form several different technical solutions. Therefore, equivalent changes made according to the claims are still within the scope of this utility model.
