[0025] Specifically, a servo motor 3 is fixedly installed on the inner wall of the chassis 1, and a ball screw 4 is fixedly installed on the output end of the power of the servo motor 3. The left end of the ball screw 4 is rotatably connected to the inner wall of the chassis 1, and a movable plate 5 is threadedly connected to the outer surface of the ball screw 4. An electric push rod 6 is fixedly installed on the bottom surface of the movable plate 5. A connecting plate 7 is fixedly installed on the telescopic end of the electric push rod 6.

A stepping motor 9 is fixedly installed on the telescopic end of the automatic telescopic rod 8, and a polishing wheel 10 is fixedly installed on the output end of the power of the stepping motor 9.

[0026] Through the above technical scheme, by providing a servo motor 3, a ball screw 4, a movable plate 5, an electric push rod 6, a connecting plate 7, an automatic telescopic rod 8, a stepper motor 9 and a polishing wheel 10, the power provided by the servo motor 3 is cooperated with the ball screw 4 to drive the movable plate 5 to move left and right, and the electric push rod 6 is used to provide motor power to drive the connecting plate 7 to move forward and backward, and the power provided by the automatic telescopic rod 8 is used to drive the stepper motor 9 to move downward, thereby achieving the effect of polishing different positions on the same side of the injection mold.

[0027] Specifically, a slide bar 11 is slidably connected inside the movable plate 5 , and ends of the slide bar 11 that are away from each other are fixedly connected to the inner wall of the chassis 1 .

[0028] Through the above technical solution, by providing the slide bar 11, the moving trajectory of the moving plate 5 is limited, so as to avoid the rotation of the moving plate 5 during movement as much as possible, thereby ensuring the stability of the movement of the moving plate 5.

The installation of the pull rod 18 makes it convenient for workers to open the glass door 17.

[0037] The working principle of the utility model is as follows: when in use, the worker first uses bolts to fix the mounting plate 16 to the ground to ensure the stability of the device, and then the worker connects the rotating motor 201, the hydraulic rod 203, the rotating motor 205, the cylinder 207, the servo motor 3, the electric push rod 6, the automatic telescopic rod 8 and the stepping motor 9 to the power supply. When the worker polishes the injection mold, the worker first places the injection mold between the two clamping plates 204, and then uses the power provided by the hydraulic rod 203 to drive the two clamping plates 204 to move toward the side close to each other. The servo motor 3 is used to drive the ball screw 4 to rotate, so that the ball screw 4 drives the moving plate 5 to move left and right, and the power provided by the electric push rod 6 is used to drive the connecting rod 5 to move left and right. The connecting plate 7 moves forward and backward, so that the connecting plate 7 drives the polishing wheel 10 to move, thereby achieving the purpose of polishing different positions on the same side of the injection mold. After the polishing of one side of the injection mold is completed, the power provided by the rotating motor 201 is used to drive the turntable 202 to rotate, so that the turntable 202 cooperates with the hydraulic rod 203 and the clamping plate 204 to drive the injection mold to flip, thereby achieving the polishing of different sides of the injection mold. When it is necessary to polish the clamping position of the injection mold, the power provided by the cylinder 207 is used to drive The movable table 208 moves upward so that the upper surface of the movable table 208 contacts the bottom surface of the injection mold, and then the power provided by the hydraulic rod 203 drives the clamping plate 204 to release the fixation of the injection mold, and then the power provided by the rotating motor 205 drives the rotating table 206 to rotate ninety degrees, and then the power provided by the hydraulic rod 203 is used to make the clamping plate 204 clamp and fix the injection mold again, and then the power provided by the rotating motor 201 drives the turntable 202 to rotate, thereby achieving the purpose of polishing the initial clamping position of the injection mold.
