The guide rod 35 is slidably connected to the moving frame 33. When the screw 32 drives the moving frame 33 to move, the guide rod 35 limits the moving frame 33 to prevent the moving frame 33 from rotating with the screw 32, so that the moving frame 33 moves smoothly. The surface of the moving frame 33 is fixedly connected with a sponge block 36. When the screw 32 rotates to drive the moving frame 33 to move, the sponge block 36 will wipe the threads on the surface of the screw 32 to clean the surface of the screw 32. The surface of the workbench 1 is fixedly connected with a buffer pad 39. When the servo motor 31 is suddenly powered off, the moving frame 33 will automatically fall to the workbench 1.

The anti-slip pad 44 improves the fit between the limit plate 43 and the mold when the limit plate 43 is fixing the mold, so that the limit plate 43 fixes the mold more stably.

[0033] In the embodiment of the utility model, when it is necessary to perform defect detection on the mold, the staff places the mold on the surface of the workbench 1, and the mold is placed in the middle of the limit plate 43. The limit plate 43 moves to both sides of the mold. When the limit plate 43 moves, the moving block 42 moves in the limit groove 41, and then the screw rod 45 is rotated to fix the position of the limit plate 43. The mold is fixed above the workbench 1. By setting the limit device 4, different types of molds can be fixed to avoid shaking of the mold during mold defect detection and affecting the detection result.
