[0048] See also Figure 1 and Figure 2 The polishing assembly 7 includes an L-shaped plate 71 fixedly mounted on the top of the main board 1, the L-shaped plate 71 is located on the outside of the top frame 5, and a second multi-section cylinder 72 is fixedly mounted on one side of the top of the L-shaped plate 71, a motor 73 is fixedly mounted on the driving end of the bottom of the second multi-section cylinder 72 through a transition plate, and a polishing disc 74 is connected to the driving end of the bottom of the motor 73 through a rotating shaft, and the polishing disc 74 is located directly above the placement disc 3.

[0049] The implementation and principle of the embodiments of the present application are as follows:

[0050] Step 1: Make the whole mirror polishing equipment in a complete assembly state, connect the electric push rod 63, the second multi-section cylinder 72, the motor 73, the fan group 12, and the first multi-section cylinder 19 to the external controller, and the controller can control them through programming, which is the prior art and will not be described in detail here;

[0051] Step 2: Place the high-hardness mold workpiece to be processed on the top of the placement plate 3, and then the two electric push rods 63 are synchronously driven to enable the two clamping strips 61 and the anti-slip pad 62 to clamp the mold workpiece, and in this process, the side end of the clamping strip 61 slides on the outer wall of the slide rail 65 through the slide groove, and the driving end of the electric push rod 63 performs a sealed sliding fit in the inner cavity of the dust box 64;

[0052] Step 3: Using the downward driving action of the second multi-section cylinder 72, the motor 73 and the polishing disc 74 are indirectly pushed downward until the polishing disc 74 contacts the surface of the mold workpiece. At this time, the motor 73 is started to drive the polishing disc 74 to run at a high speed, so as to achieve mirror polishing of the surface of the mold workpiece;

[0053] Step 4: Based on the operation process of step 3, the fan group 12 is started to accelerate the circulation rate of the gas inside and outside the bottom box 10, so that the fixed bucket 8, the circulation frame 9, and the interior of the bottom box 10 form a negative pressure cavity together, so that the debris generated during the polishing of the mold workpiece flows through the top frame 5 and the through groove 2 to the interior of the fixed bucket 8, the circulation frame 9, and the bottom box 10, and then indirectly discharged from the interior of the bottom box 10, and the gas mixed with the debris flows through the filter plate 14 in the bottom box 10, so that the debris can be passively filtered out, and the filtered debris is accumulated on the top of the filter plate 14 and the inner side of the built-in frame 13, so as to prevent the debris from affecting the external working environment, effectively reduce the manual cleaning labor of the debris, and indirectly improve the overall work efficiency;

[0054] Step 5: After the mirror polishing operation in step 3 is completed, the motor 73 and the polishing disc 74 are indirectly reset vertically, and the two clamping strips 61 and the anti-slip pad 62 are indirectly reset horizontally. At this time, the mold workpiece can be extracted and the next round of mirror polishing operation can be carried out;

[0055] Step six: Based on the state of step four, when it is necessary to clean the debris on the filter plate 14, first put the fan group 12 in the closed state, and use the two first multi-section cylinders 19 to synchronously drive the two connecting blocks 20 to move downward, thereby indirectly moving the bottom box 10 as a whole downward and away from the bottom of the circulation frame 9, and then use the pull rod 17 to vertically extract the filter plate 14 and the built-in frame 13, so that the block 15 is disengaged from the inside of the card slot 16, and the filter plate 14 and the built-in frame 13 are disengaged from the inside of the bottom box 10. At this time, the surface of the filter plate 14 can be cleaned.

[0056] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
