[0002] CNC technology is a technology that uses computers to implement digital program control, mainly used to control machine tools for automated machining. During CNC machining, automatic clamping devices are needed to fix parts in place for easy processing. However, existing clamping devices have relatively simple functions and lack protective features, leading to potential worker injuries during machining. Therefore, it is necessary to propose an automatic mold clamping device for CNC machining to solve the above problems. Utility Model Content

[0004] To achieve the above objectives, this utility model provides the following technical solution: an automatic mold clamping device for CNC machining machines, including a base, a mounting seat on the base, a protective cover on the upper surface of the base, electric cylinders fixedly installed on the inner walls of both sides of the protective cover, clamping plates fixedly installed at the ends of the telescopic sections of the two electric cylinders, the two clamping plates being configured to cooperate, and a cleaning scraper being provided in the middle section of the telescopic sections of the two electric cylinders.

[0005] Preferably, the base has two waste holes at its top, and a waste collection box is provided on the base, with the waste holes communicating with the waste collection box.

[0006] Preferably, two protective doors are rotatably installed on the protective cover, and the two protective doors are symmetrically arranged on the side away from the mounting base. A perforated locking plate is provided on the inner side of the protective door. A movable plate is fixedly installed on the cleaning scraper near the protective door. A round tube is fixedly installed on the movable plate near the protective door. An insert is slidably installed on the outer side of the round tube. The insert cooperates with the perforated locking plate.

[0007] Preferably, a compression spring is provided inside the circular tube, and the two ends of the compression spring are fixedly connected to the inner walls of the circular tube and the insertion tube at opposite ends.

[0008] Preferably, the protective door is provided with an observation window, and the observation window is embedded with transparent glass.

[0009] The technical effects and advantages of this utility model are as follows:

[0010] 1. Start the electric cylinder to drive the two clamping plates to move closer to each other and automatically clamp the workpiece. At the same time, the electric cylinder can also drive the cleaning scraper to move, which can push the waste chips processed on the upper surface of the base into the waste hole and then into the waste collection box for storage. This can automatically clean up the waste chips and reduce the impact of waste chips on the workpiece processing.

[0011] 2. During operation, when the electric cylinder drives the clamping plate to hold the workpiece, the insertion tube can lock the protective door. Therefore, the protective door and protective cover can completely isolate the processing machinery and prevent workers from contacting the workpiece during processing. Thus, there will be no situation where workers are injured, the safety is high, and it can also prevent waste from flying into the working chamber and affecting the working environment, making it highly functional.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] This utility model provides, for example Figures 1-3 The automatic clamping device for molds used in CNC machining machines shown includes a base 1 and a mounting seat 2 on the base 1. The mounting seat 2 is mainly used to install milling equipment or grinding equipment, and can be set according to actual conditions, so it is not limited.

[0018] To address the issue of existing clamping devices having limited functionality and lacking protective features, which could lead to worker injuries during processing, this invention provides a protective cover 3 on the upper surface of the base 1. Electric cylinders 4 are fixedly installed on the inner walls of both sides of the protective cover 3. Clamping plates 5 are fixedly installed at the ends of the telescopic sections of the two electric cylinders 4, and the two clamping plates 5 are designed to work together. A cleaning scraper 6 is installed in the middle section of the telescopic sections of the two electric cylinders 4. Two waste holes 13 are located at the top of the base 1, and a waste collection box 14 is installed on the base 1, with the waste holes 13 connected to the waste collection box 14. During operation, the workpiece is placed within the circle at the center position, and the electric cylinders 4 are activated to move the two clamping plates 5 closer together, automatically clamping the workpiece. During or after workpiece clamping, the electric cylinders 4 also move the cleaning scraper 6, pushing the waste debris from the upper surface of the base 1 into the waste holes 13, which are then stored in the waste collection box 14. This automatically cleans the waste debris, reducing its impact on workpiece processing.

[0019] Two protective doors 11 are rotatably mounted on the protective cover 3. The two protective doors 11 are symmetrically arranged on the side away from the mounting base 2. A perforated locking plate 12 is provided on the inner side of the protective door 11. A movable plate 7 is fixedly installed on the cleaning scraper 6 near the protective door 11. A round tube 8 is fixedly installed on the movable plate 7 near the protective door 11. An insertion tube 9 is slidably installed on the outer side of the round tube 8. The insertion tube 9 cooperates with the perforated locking plate 12. During operation, after the workpiece is placed on the upper surface of the base 1, the two protective doors 11 are closed, and the clamp is driven by the electric cylinder 4. When plate 5 clamps the workpiece, the cleaning scraper 6 can drive the moving plate 7 to move closer together, and the moving plate 7 can drive the round tube 8 to move closer together, so that the two insertion tubes 9 move closer together and are inserted into the two perforated locking plates 12 on the protective door 11. At this time, the protective door 11 can be locked. In this way, during processing, the protective door 11 and the protective cover 3 can completely isolate the processing machinery, which can prevent the worker from contacting the workpiece during processing. Therefore, there will be no situation that will harm the worker, the safety is high, and it can also prevent waste from flying into the working chamber and affecting the environment of the workshop.

[0020] A compression spring 10 is installed inside the round tube 8, and the two ends of the compression spring 10 are fixedly connected to the inner walls of the round tube 8 and the insertion tube 9 respectively, which are far apart from each other. The compression spring 10 allows the round tube 8 to continue to move after the insertion tube 9 is inserted into the perforated locking plate 12, so that the clamping plates 5 can continue to move closer to each other to clamp smaller workpieces.

[0021] The protective door 11 is equipped with an observation window, which has a transparent glass panel embedded in it.
