[0019] 1. By setting the clamping assembly and the rotating assembly, the mold to be inspected can be placed between the two rubber discs during use. After placement, the first motor is started to rotate the threaded rod, and the rotation of the threaded rod drives the clamping bar to move to the left.

After the contact, the roughness detector can detect the polishing degree of the mold, which is very convenient;

[0021] 3. By setting a cleaning component, when the polishing degree of the mold is tested, the second electric telescopic rod can be started to move the connecting frame downward, and the connecting frame moves downward to drive the sponge tube downward to fit the mold. After fitting, the water pump is started to inject the water in the water tank into the net barrel. The water entering the net barrel will be absorbed by the sponge tube. At this time, the fourth motor is started to rotate the second gear. At this time, the tooth plate will drive the moving frame to move. The moving frame moves and drives the sponge tube that has absorbed water to move to wipe the part to be tested of the mold. After wiping, the residue generated during the polishing process can be prevented from affecting the detection of the detection head;

[0022] 4. By setting up a drying component, the sponge tube starts the heater during the process of wiping the mold. The hot air generated after the heater is started will pass downward through the air outlet hose into the air outlet barrel. The hot air entering the air outlet barrel will be sprayed toward the mold through the air outlet hole to dry it. After drying, water stains can be prevented from affecting the detection of the detection head. BRIEF DESCRIPTION OF THE DRAWINGS
