[0038] Reference Figure 2-Figure 4The inner wall of the workbench 6 is slidably connected with two groups of movable plates 9, and two groups of oblique grooves are opened on the surface of the movable plate 9. The bottom end of the outer wall of the clamping block 10 is slidably connected to the inner wall of the oblique groove, and the movable plate 9 is pushed and moved on the inner wall of the workbench 6, so that the bottom ends of the two groups of clamping blocks 10 are moved in their oblique grooves, thereby achieving the effect of approaching each other, the bottom end of the outer wall of the workbench 6 is slidably connected to the inner wall of the top of the shell 1, and the inner wall of the top of the workbench 6 is slidably connected with two groups of clamping blocks 10. The outer walls of the two groups of movable plates 9 are fixedly connected with L rods 11, and the movement of the L rods 11 pushes the two groups of movable plates 9 to move on the inner wall of the workbench 6. The L rods 11 are slidably connected to the inner wall of the workbench 6, and the movable seat 14 is slidably connected to the inner wall of the workbench 6. The inner wall of the workbench 6 is provided with a cavity, and the upper and lower positions of the movable seat 14 are matched with the inner wall of the cavity.

[0041] Reference Figure 5-Figure 6 The outer side wall of the fixed plate 2 is fixedly connected to a collecting box 7, and a cover plate is hinged on the top of the collecting box 7. By opening the cover plate, the debris in the collecting box 7 can be uniformly processed, and the collecting box 7 is provided with a fan 17, and a dust suction port 8 is fixedly connected to the surface of the fan 17. The fan 17 is a prior art, and a motor is arranged inside. A hose is connected between the dust suction port 8 and the fan 17. The dust suction port 8 is started by starting the fan 17 to generate suction to centrally suck out the processing debris on the surface of the workbench 6. The inner wall of the collecting box 7 is slidably connected to a handle 18, and the inner wall of the collecting box 7 is provided with guide grooves that fit on both sides of the handle 18, so that the handle 18 can only move up and down on the inner wall of the collecting box 7 and cannot be separated from its inner wall.

[0042] Reference Figure 6The inner wall of the handle 18 is hinged with a hinged rod 19, and one end of the hinged rod 19 away from the handle 18 is hinged to the outer wall of the bottom end of the push plate 21. By the descent of the handle 18, one end of the hinged rod 19 is synchronously descended with it, so that the bottom end of the hinged rod 19 pushes the push plate 21 to move laterally on the inner wall of the collection box 7, and the end of the dust suction port 8 away from the fan 17 is fixedly connected to the outer wall of the mounting seat 3. The inner wall of the collection box 7 is elastically connected to the push plate 21 through a connecting spring 20, and one end of the connecting spring 20 is fixedly connected to the outer wall of the push plate 21. The other end of the spring 20 is fixedly connected to the inner wall of the collection box 7. When the hinged rod 19 pushes the push plate 21 to move on the inner wall of the collection box 7, when the handle 18 is released, the push plate 21 will be elastically acted upon by the connecting spring 20, and the push plate 21 will be restored to its initial position to wait for the next movement. The push plate 21 is slidably connected to the inner wall of the collection box 7, and the push plate 21 moves laterally on the inner wall of the collection box 7, so that the mold waste in the collection box 7 can be compressed, thereby reducing the space occupied by the waste in the collection box 7 due to its shape.

[0043] Working principle: When processing the injection mold, place the mold to be processed between the two groups of clamping blocks 10 on the surface of the workbench 6. By setting four groups of clamping blocks 10, two groups of injection molds can be processed at the same time. At this time, the moving seat 14 can be pushed to move on the inner wall of the workbench 6. During the movement, the moving seat 14 will drive the two groups of L rods 11 and the moving plate 9 to move synchronously on the inner wall of the workbench 6 until the movement of the moving plate 9 allows the two groups of clamping blocks 10 to move relative to each other in the inclined groove, and because the surface of the clamping block 10 is slidably connected to the linear groove of the workbench 6 The clamping blocks 10 are brought close to each other on the inner wall of the workbench 6, thereby fixing the injection mold. At the same time, when the movable seat 14 moves, the grooves on its surface squeeze the inclined surface of the wedge block 16, pushing it upward on the inner wall of the workbench 6 until the next set of grooves, whereupon it is elastically acted upon by the reset spring 15 to restore it to its initial position, to engage with the grooves at the current position, to fix the position of the movable seat 14, and this cycle is repeated until the four sets of clamping blocks 10 complete the clamping of the injection mold, and the movable seat 14 stays at the current position of the workbench 6.

[0044] At this time, the motor in the mounting base 3 can be started to control the cutter head 4 to rotate at high speed, so as to process the surface of the injection mold. During the processing, the two sets of threaded rods 5 on the inner wall of the shell 1 can be used to adjust the workbench 6 for lateral and longitudinal movement, so as to facilitate the processing of multiple positions of the injection mold.

[0045] At the same time, excessive debris may be generated on the surface of the workbench 6 during processing. At this time, the fan 17 can be started to allow the dust suction port 8 to absorb the processing debris on the surface of the workbench 6 into the inner wall of the collection box 7. When the space inside the collection box 7 is about to be full, the handle 18 can be grasped to allow it to descend on the inner wall of the collection box 7. When the handle 18 is descending, one end of the hinged rod 19 will follow it to descend synchronously, so that the bottom end of the hinged rod 19 pushes the push plate 21 to move laterally on the inner wall of the collection box 7, so that the push plate 21 compresses the space on the inner wall of the collection box 7. After the compression is completed, when the handle 18 is released, the push plate 21 will be subjected to the elastic action of the connecting spring 20, and the push plate 21 will drive the hinged rod 19 and the handle 18 to synchronously restore to the initial position to wait for the next movement.

[0046] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
