EDM equipment is mainly used to process various high-hardness materials (such as cemented carbide and hardened steel, etc.) and molds and parts with complex shapes, as well as cutting, grooving and removing tools (such as drills and taps) broken in workpiece holes.

[0003] Chinese patent CN217453162U discloses an electrospark machining device for metal mold manufacturing, which relates to the technical field of electrospark machining devices. The electrospark machining device for metal mold manufacturing includes a workbench, a storage tank is provided at the top of the workbench, a placement table is provided inside the storage tank, a fixing frame is provided at the rear of the top of the workbench, an electrospark machining device is provided at the front of the fixing frame, an air suction head is provided at the front of the electrospark machining device, a gas purifier is provided at the right part of the workbench, a controller is provided at the right part of the rear of the workbench, and ultrasonic generators are provided on the left and right parts of the storage tank.

[0004] The metal mold processing parts processed by the electrospark machining equipment will stick to metal debris, affecting the processing efficiency.

[0030] See also Figures 1-6 As shown, the utility model is an electric spark machining equipment for metal mold manufacturing, including a processing table 1, a filter screen 2 is slidably connected inside the processing table 1, a driving component 3 and a support component 4 are provided on the side of the processing table 1, a circulation component 5 is provided on the back of the processing table 1, and a cutting component 6 is provided on the top of the processing table 1. The support component 4 is rotatably connected to the processing table 1, the driving component 3 is used to push the filter screen 2 up and down and drive the support component 4 to rotate, the circulation component 5 is used to make the insulating liquid in the processing table 1 flow through the filter screen 2, and the cutting component 6 is used to cut the mold on the processing table 1.

[0031] Insulating liquid is injected into the processing table 1, and then the metal mold to be processed is placed on the boss in the processing table 1. The circulation component 5 is started to make the insulating liquid in the processing table 1 flow, and the cutting component 6 is started to process the metal mold in the processing table 1. The debris generated during the processing falls into the insulating liquid in the processing table 1, and the insulating liquid drives the debris to move downward. The debris is blocked by the filter 2 in the processing table 1 to prevent the debris from drifting in the insulating liquid and affecting normal processing. When the filter 2 needs to be cleaned, the drive component 3 is started to drive the filter 2 to move upward. At this time, the drive component 3 no longer presses down the support component 4. The support component 4 can rotate under the action of gravity, so that the support component 4 drives the circulation component 5 to avoid, making it easy to remove the filter 2.

[0032] The utility model connects the filter screen 2 and the circulation component 5. The circulation component 5 absorbs the insulating liquid in the processing table 1 and makes it move downward. The insulating liquid drives the slag to move synchronously. During the movement, the slag is blocked by the filter screen 2 in the processing table 1. Then the circulation component 5 injects the insulating liquid into the processing table 1 from above, and the circulation component 5 continuously generates suction to make the insulating liquid press down the slag, thereby preventing the slag from drifting around in the insulating liquid on the processing table 1 and affecting normal processing.

[0033] In one embodiment, for the above-mentioned drive component 3, the drive component 3 includes a first electric push rod 301, the movable end of the first electric push rod 301 is fixedly connected to a lifting plate 302, the top of the lifting plate 302 is located below the filter 2, and the bottom of the lifting plate 302 is located above the support component 4.

[0034] An ear plate is fixedly connected to the side of the filter 2, and the lifting plate 302 is located below the ear plate. When the first electric push rod 301 is started, the first electric push rod 301 pushes the lifting plate 302 to move upward, and the lifting plate 302 drives the filter 2 to move synchronously through the ear plate, so that the filter 2 is moved out of the processing table 1.

[0036] When the lifting plate 302 moves upward, the lifting plate 302 no longer presses the rotating rod 403. At this time, the rotating rod 403 can rotate around the fixed rod 401 under the action of gravity, so that the cross bar 404 and the pipe clamp 405 on the rotating rod 403 rotate downward, and the pipe clamp 405 can avoid the raised filter screen 2.

[0037] In one embodiment, for the above-mentioned circulation component 5, the circulation component 5 includes a water pump 501, and the outer surface of the water pump 501 is fixedly connected with a first connecting pipe 502 and a second connecting pipe 503, respectively. A circular hole 504 is opened inside the processing table 1, and the first connecting pipe 502 is fixedly connected to the circular hole 504, and the second connecting pipe 503 is fixedly connected to the pipe clamp 405.

[0038] The water pump 501 is started, and the water pump 501 draws the insulating liquid in the processing table 1 through the first connecting pipe 502 and the circular hole 504. The insulating liquid drives the debris generated during the processing to move. The debris is blocked by the filter screen 2. Due to the suction generated by the circular hole 504, the debris can be fixed on the filter screen 2 to prevent the debris from drifting around in the insulating liquid on the processing table 1. Then, the insulating liquid is ejected through the second connecting pipe 503 on the water pump 501 and falls into the processing table 1 again. When the pipe clamp 405 rotates, the second connecting pipe 503 on the pipe clamp 405 is bent to avoid the filter screen 2. The second connecting pipe 503 is a hose.

[0040] The bracket 601 supports the slide rail 602, allowing the sliding seat 603 to slide smoothly on the slide rail 602. The sliding seat 603 drives the tool electrode 605 to move above the metal mold to be processed, and then the second electric push rod 604 pushes the tool electrode 605 down to process the metal mold.

[0044] Through the above technical solution, 1. through the connection between the filter screen 2 and the circulation component 5, the circulation component 5 absorbs the insulating liquid in the processing table 1 and makes it move downward. The insulating liquid drives the slag to move synchronously. During the movement, the slag is blocked by the filter screen 2 in the processing table 1. Then the circulation component 5 injects the insulating liquid into the processing table 1 from above, and the circulation component 5 continuously generates suction to make the insulating liquid press down the slag, thereby preventing the slag from drifting around in the insulating liquid on the processing table 1 and affecting normal processing; 2. through the connection between the filter screen 2 and the circular hole 504, the filter screen 2 and the circular hole 504 are both located in the processing table 1.

During the movement, the slag is blocked by the filter screen 2, and the circular hole 504 continuously generates suction, thereby preventing the slag from floating around in the insulating liquid and affecting normal processing.
