The preliminary cleaning stage is completed. After the preliminary cleaning is completed, under the action of the stepper motor 9, the rotating bracket 3 enters the second cleaning pool D, and the rotating motor 10 drives the rotating bracket 3 to rotate to immerse the test mold in the cleaning liquid, and then the rotating motor 10 drives the rotating bracket 3 to rotate for rotating cleaning for 10 minutes to complete the final cleaning stage. There are two ways to return the test mold after the final cleaning. One is to return to the heating zone F through the track 2 under the action of the stepper motor 9 to dry the test mold, and then send it to the installation area E and the display shows that the cleaning is completed, the indicator light is on, and the cleaning of the test mold is completed; the other is to enter the heating zone F under the action of the stepper motor 9 and the extension section 14 to dry the test mold, and then send it to the installation area E and the indicator light is on, indicating that the cleaning of the test mold is completed. At the same time, other rotating brackets 3 on the rear track 2 can still be heated, preliminarily cleaned and finally cleaned under the action of the stepper motor 9 and the rotating motor 10, forming a cycle cleaning to improve work efficiency.

[0035] The controller 11 is also connected to indicator lights that display the working status corresponding to the installation area E, the heating area F, the first cleaning pool C, and the second cleaning pool D, and controls the switches and working indicator lights for starting the stepper motor 9, the rotating motor 10, and the infrared heater 5, so that the cleaning work can be completed manually or automatically under the detection of the laser position sensor, and the personnel who need to be organized can put in the test mold to be cleaned or take out the cleaned test mold.
