[0003] Its reasonable structure can clean up dust and debris generated during processing, preventing dust and debris from affecting the health of workers and subsequent processing.
[0004] The technical solution in the prior art has the effect of cleaning dust and debris, but the defects are also more obvious. For example, when using fan blades to generate airflow to clean dust, the dust will still adhere to the inside of the CNC milling machine. When using water jets to clean debris, it is well known that spraying water during milling reduces the machining accuracy of the workpiece. This solution has disadvantages in cleaning both dust and debris. Utility Model Content
[0005] To address the shortcomings of existing technologies, this utility model provides a CNC milling machine for mold processing. It solves the problems of dust still adhering to the inside of the CNC milling machine when using fan blades to generate airflow for dust removal, and water jet cleaning for debris removal, which is known to reduce the machining accuracy of the workpiece during milling. Both solutions have drawbacks in cleaning dust and debris.
[0006] To achieve the above objectives, the present invention provides the following technical solution: a CNC milling machine for mold processing, comprising a CNC milling machine, wherein an operating table is fixedly connected inside the CNC milling machine, and an air supply structure is fixedly connected to the side of the operating table; an opening at the same horizontal level as the air supply structure is provided on the back of the CNC milling machine, and a waste material assembly is fixedly connected to the side of the opening.
[0007] The waste assembly includes a conical opening fixedly connected to the side of the inlet, and a surrounding plate fixedly connected to the bottom surface of the conical opening. An equipment plate is fixedly connected inside the surrounding plate. Several air vents are opened on the top surface of the equipment plate, and a negative pressure impeller structure is fixedly connected inside the air vents. A connecting structure is fixedly connected to the side of the surrounding plate in an axially symmetrical manner, and a waste bin is fixedly connected to the side of the connecting structure.
[0008] In one specific embodiment, the connection structure includes an insert block fixedly connected to the side of the enclosure, and a square tube is inserted into the surface of the insert block. Limiting holes are opened at both ends of the insert block and the square tube, and a limiting rod is inserted into the inside of the limiting hole.
[0009] In one specific embodiment, both ends of the limiting rod are provided with insertion holes, and elastic inserts for limiting are inserted into the insertion holes.
[0010] In one specific embodiment, the top surface of the waste bin is provided with a sealing gasket to increase the sealing performance, and the bottom surface of the waste bin is fixedly connected with a gauze layer that penetrates it.
[0011] In one specific embodiment, the air supply structure includes an air collector hood fixedly connected to the side of the operating table, and a base plate is fixedly connected to the bottom surface of the air collector hood. An installation opening is provided on the top surface of the base plate, and a high-speed fan is fixedly connected inside the installation opening.
[0012] In one specific embodiment, the bottom surface of the CNC milling machine is connected to adjustable feet in a rectangular array with threaded connections, and the side of the CNC milling machine is provided with a control panel for operation.
[0013] Compared with the prior art, this utility model provides a CNC milling machine for mold processing, which has the following beneficial effects:
[0014] In the technical solution disclosed in this utility model, when the workpiece on the operating table is processed by the machining structure inside the CNC milling machine, the air supply structure blows the waste and dust towards the conical opening, and the negative pressure impeller structure generates negative pressure inside, sucking the waste and dust into the waste box, effectively improving the situation of dust adhering to the inside of the CNC milling machine and avoiding the impact of water flow cleaning on the workpiece machining accuracy.
[0015] The air supply structure and waste collection component of this invention address the dust and debris generated during workpiece processing on the workbench surface. A high-speed fan generates a high-speed airflow, which is discharged through a conical air collector. Because the air collector's outlet is narrow and closely fitted to the workbench surface, the airflow carries dust and debris closer to the conical opening. Simultaneously, multiple negative pressure impellers powered by an external power source generate a high-intensity negative pressure within the enclosure and conical opening, drawing the dust and debris carried by the airflow into the conical opening. The dust and debris then fall into the waste collection bin, effectively improving the situation where simple fan blowing causes dust to scatter and adhere to the inner surface of the CNC milling machine. Furthermore, it avoids water impact affecting workpiece processing accuracy while simultaneously cleaning dust and debris. Attached Figure Description

[0022] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.
[0023] Figures 1-4 As an embodiment of the present utility model, a CNC milling machine for mold processing includes a CNC milling machine 1, an operating table 2 is fixedly connected inside the CNC milling machine 1, and an air supply structure 3 is fixedly connected to the side of the operating table 2. An opening with the same horizontal line as the air supply structure 3 is opened on the back of the CNC milling machine 1, and a waste material assembly 4 is fixedly connected to the side of the opening.
[0024] The specific problem addressed in this embodiment is that while using fan blades to generate airflow for dust removal results in dust still adhering to the interior of the CNC milling machine, and using water jets to remove debris is known to reduce workpiece machining accuracy during milling. Both solutions have drawbacks in dust and debris removal. This invention utilizes a system where, during the machining of the workpiece on the operating table by the internal machining structure of the CNC milling machine, the air supply structure 3 blows waste and dust towards the conical inlet 41. The negative pressure impeller structure 44 creates negative pressure inside, drawing the waste and dust into the waste bin 46. This effectively improves the situation of dust adhering to the interior of the CNC milling machine 1 and avoids the impact of water jet cleaning on workpiece machining accuracy.
[0025] The air supply structure 3 includes an air collector 31 fixedly connected to the side of the operating table 2, and a base plate 32 fixedly connected to the bottom surface of the air collector 31. An installation port is opened on the top surface of the base plate 32, and a high-speed fan 33 is fixedly connected inside the installation port. The waste assembly 4 includes a conical opening 41 fixedly connected to the side of the opening, and a surrounding plate 42 fixedly connected to the bottom surface of the conical opening 41. An equipment plate 43 is fixedly connected inside the surrounding plate 42. Several air vents are opened on the top surface of the equipment plate 43, and a negative pressure impeller structure 44 is fixedly connected inside the air vents. A connecting structure 45 is fixedly connected to the side of the surrounding plate 42 in an axially symmetrical manner, and a waste bin 46 is fixedly connected to the side of the connecting structure 45. In this specific embodiment, the connecting structure 45 includes an insert block 451 fixedly connected to the side of the surrounding plate 42, and a square tube 452 is inserted into the surface of the insert block 451. Limiting holes are opened at both ends of the insert block 451 and the square tube 452, and a limiting rod 453 is inserted into the inside of the limiting holes. Dust and debris are generated during workpiece processing on the surface of the operating table 2. The high-speed fan 33 generates a high-speed airflow, which is discharged through the conical air collector 31. Because the air outlet of the air collector 31 is narrow and fits closely to the surface of the operating table 2, the airflow carries dust and debris closer to the conical opening 41. At the same time, multiple negative pressure impeller structures 44 are powered by an external power source, which generates a high-intensity negative pressure inside the enclosure 42 and the conical opening 41. This draws the dust and debris carried by the airflow into the conical opening 41, where they fall and soak into the waste bin 46 for collection. This effectively improves the situation where dust is scattered and adheres to the inner surface of the CNC milling machine 1 due to simple fan blowing. At the same time, it avoids water flow impact from affecting the workpiece processing accuracy while completing the dust and debris cleaning operation.
[0026] In this specific embodiment, the connecting structure 45 includes an insert block 451 fixedly connected to the side of the enclosure 42, and a square tube 452 is inserted into the surface of the insert block 451. Limiting holes are opened at both ends of the insert block 451 and the square tube 452, and a limiting rod 453 is inserted into the inside of the limiting hole. Both ends of the limiting rod 453 are provided with insertion holes, and an elastic insert 5 for limiting is inserted into the inside of the insertion hole.
[0027] By setting the connecting structure 45, the insert 451, which is fixed to the side of the enclosure 42, is inserted into the inside of the square tube 452, and the square tube 452 is fixed to the side of the waste bin 46. Then, the limiting rod 453 is inserted into the limiting hole to complete the connection operation of the insert 451 and the square tube 452. This allows for quick assembly and disassembly between the waste bin 46 and the enclosure 42, facilitating the cleaning of waste inside the waste bin 46. At the same time, the elastic insert 5 can prevent the limiting rod 453 from loosening and causing the installation to fall off.
[0028] The top surface of the waste bin 46 is provided with a sealing gasket 6 to increase the sealing performance, and the bottom surface of the waste bin 46 is fixedly connected with a gauze layer 7 that passes through it.
[0029] The sealing gasket 6 can increase the sealing between the waste bin 46 and the enclosure 42 to prevent dust leakage. At the same time, the gauze layer 7 can discharge the gas inside the waste bin 46 and retain dust and debris.
[0030] The control method of this utility model is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail.
