Description

Technical Field

[0001] This utility model relates to the field of mold electrode processing technology, and in particular to a CNC machine tool specifically used for processing mold electrodes. Background Technology

[0002] Mold electrode machining is a machining method that uses electrical energy to remove or shape materials. It applies an electric field between the electrode and the workpiece, and uses the heat energy generated by electric spark discharge to melt and remove excess material from the workpiece, thereby achieving the machining purpose. Mold electrode machining has the characteristics of high machining accuracy, fast machining speed and good surface quality, and therefore has been widely used in mold manufacturing, aerospace and automobile manufacturing and other fields.

[0003] For example, Chinese patent CN221538363U discloses a CNC EDM machine tool suitable for mold processing. This EDM machine tool can only suck or spray exhaust gas and spray coolant from a single direction, resulting in poor exhaust gas suction and cooling effect. Therefore, we propose a CNC machine tool specifically for processing mold electrodes. Utility Model Content

[0004] The purpose of this invention is to provide a CNC machine tool specifically for processing mold electrodes, which has the advantages of good cooling effect and good exhaust gas extraction effect.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: A CNC machine tool specifically for processing mold electrodes, comprising a base plate, a Z-axis moving seat and a vertical frame mounted on the base plate, a clamping platform mounted on the Z-axis moving seat, an X-axis moving seat mounted on the vertical frame, a Y-axis moving seat mounted on the X-axis moving seat, a guide plate mounted on the Y-axis moving seat, a horizontal plate mounted on the guide plate, a mounting cover mounted on the horizontal plate, an electric spark generator mounted inside the mounting cover, and a connecting frame mounted on the clamping platform. A rotating sleeve is mounted on the outer side of the mounting cover, a rotating ring is mounted on the rotating sleeve, and a ring-shaped distribution of cleats is mounted on the inner side of the rotating ring. A drive assembly that meshes with the cleats is mounted on the horizontal plate, and a cooling assembly is mounted on the horizontal plate. One end of the cooling assembly is connected to the connecting frame, and the other end of the cooling assembly is sleeved outside the rotating sleeve. An adsorption assembly is also mounted on the rotating sleeve.

[0006] By adopting the above technical solution, the EDM generator realizes multi-dimensional processing of the mold through the Z-axis moving seat, X-axis moving seat and Y-axis moving seat. When waste gas is generated and the temperature rises during the processing, the drive component starts and engages with the cleaver, causing the rotating sleeve to rotate outside the mounting cover, thereby causing the cooling component and adsorption component to rotate, improving the adsorption effect of waste gas and the cooling effect of the mold. The sprayed coolant is collected through the connecting frame, realizing the recycling of coolant.

[0007] A further feature of this invention is that the clamping platform is provided with a clamping groove.

[0008] By adopting the above technical solution, it is convenient to fix the mold.

[0009] A further feature of this invention is that the inner bottom wall of the side of the connecting frame that communicates with the cooling assembly is inclined downwards.

[0010] By adopting the above technical solution, it is convenient for the connecting frame to collect the sprayed coolant for extraction by the cooling components.

[0011] A further feature of this invention is that the drive assembly includes a motor mounted on the horizontal plate, the output shaft of the motor passing through the horizontal plate and having a gear mounted thereon, the gear meshing with a locking tooth.

[0012] By adopting the above technical solution, the motor starts and drives the gear to rotate. The gear meshes with the clasp, causing the rotating sleeve to rotate outside the mounting cover. This, in turn, causes the cooling component and the adsorption component to rotate, improving the adsorption effect of the exhaust gas and the cooling effect on the mold.

[0013] A further feature of this invention is that the cooling assembly includes a hydraulic pump mounted on a horizontal plate and an inlet pipe connecting the connecting frame to the water inlet of the hydraulic pump, wherein the inlet pipe is a flexible hose.

[0014] A further feature of this invention is that the cooling assembly also includes a liquid reservoir installed outside the rotating sleeve and a spray pipe connected to the bottom of the liquid reservoir.

[0015] A further feature of this invention is that the inner top wall of the liquid storage tank is an opening, and the outlet of the hydraulic pump is located above the liquid storage tank.

[0016] By adopting the above technical solution, the hydraulic pump starts and draws the coolant collected in the connecting frame through the hose. When the rotating sleeve rotates outside the mounting cover, the coolant sprayed from the water outlet of the hydraulic pump will always fall into the reservoir and then be sprayed out through the nozzle, reducing the temperature generated during processing.

[0017] A further feature of this invention is that the adsorption assembly includes a fan mounted on the rotating sleeve and an adsorption pipe connected to the fan.

[0018] By adopting the above technical solution, the fan starts up and adsorbs the waste gas generated during the processing through the adsorption pipe, thus purifying the working environment.

[0019] A further feature of this invention is that the angle between the adsorption pipe and the nozzle is 180 degrees.

[0020] By adopting the above technical solution, the coolant sprayed from the nozzle and the suction generated by the adsorption pipe will not interfere with each other.

[0021] A further feature of this invention is that a filter screen may be provided on the inner wall of the inlet pipe near the connecting frame.

[0022] By adopting the above technical solution, it is easy to filter out impurities contained in the coolant.

[0023] The beneficial effects of this utility model are: when waste gas is generated and the temperature rises during the processing, the drive component starts and engages with the locking teeth, causing the rotating sleeve to rotate outside the mounting cover, thereby causing the cooling component and the adsorption component to rotate, which improves the adsorption effect of waste gas and also improves the cooling effect of the mold. The sprayed coolant is collected through the connecting frame, realizing the recycling of the coolant. Attached Figure Description

[0028] The technical solution of this utility model will now be clearly and completely described with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0029] Please see Figure 1-2 This utility model provides a CNC machine tool specifically for processing mold electrodes, including a base plate 1, a Z-axis movable seat 2 and a vertical frame 3 mounted on the base plate 1, a clamping platform 4 mounted on the Z-axis movable seat 2, an X-axis movable seat 5 mounted on the vertical frame 3, a Y-axis movable seat 6 mounted on the X-axis movable seat 5, a guide plate 7 mounted on the Y-axis movable seat 6, a horizontal plate 8 mounted on the guide plate 7, a mounting cover 9 mounted on the horizontal plate 8, an electric spark generator 10 mounted inside the mounting cover 9, and a connecting frame 11 mounted on the clamping platform 4. A rotating sleeve 12 is mounted on the outer side of the mounting cover 9, a rotating ring 13 is mounted on the rotating sleeve 12, and a ring-shaped distribution of cleats 14 is mounted on the inner side of the rotating ring 13. A drive assembly that meshes with the cleats 14 is mounted on the horizontal plate 8, and a cooling assembly is mounted on the horizontal plate 8. One end of the cooling assembly is connected to the connecting frame 11, and the other end of the cooling assembly is sleeved outside the rotating sleeve 12. An adsorption assembly is also mounted on the rotating sleeve 12.

[0030] The EDM generator 10 achieves multi-dimensional processing of the mold through the Z-axis moving seat 2, X-axis moving seat 5 and Y-axis moving seat 6. During the processing, when exhaust gas is generated and the temperature rises, the drive component starts and engages with the cleat 14, causing the rotating sleeve 12 to rotate outside the mounting cover 9, thereby causing the cooling component and adsorption component to rotate, improving the adsorption effect of exhaust gas and the cooling effect of the mold. The sprayed coolant is collected through the connecting frame 11, realizing the recycling of coolant.

[0031] The clamping platform 4 is provided with a clamping slot 41 to facilitate the fixing of the mold.

[0032] The inner bottom wall of the connecting frame 11 on the side connected to the cooling component is inclined downwards, which makes it easier for the connecting frame 11 to collect the sprayed coolant for the cooling component to extract.

[0033] The drive assembly includes a motor 15 mounted on the horizontal plate 8. The output shaft of the motor 15 passes through the horizontal plate 8 and is equipped with a gear 16. The gear 16 meshes with the retaining teeth 14. When the motor 15 starts, it drives the gear 16 to rotate. The gear 16 meshes with the retaining teeth 14, causing the rotating sleeve 12 to rotate outside the mounting cover 9. This causes the cooling assembly and the adsorption assembly to rotate, improving the adsorption effect of the exhaust gas and the cooling effect of the mold.

[0034] The cooling assembly includes a hydraulic pump 17 mounted on the horizontal plate 8 and an inlet pipe 18 connecting the connecting frame 11 to the water inlet of the hydraulic pump 17. The inlet pipe 18 is a flexible hose. The cooling assembly also includes a liquid storage cover 19 mounted outside the rotating sleeve 12 and a spray pipe 20 connected to the bottom of the liquid storage cover 19. The inner top wall of the liquid storage cover 19 is open. The water outlet of the hydraulic pump 17 is located above the liquid storage cover 19. When the hydraulic pump 17 is started, it draws the coolant collected in the connecting frame 11 through the flexible hose. When the rotating sleeve 12 rotates outside the mounting cover 9, the coolant sprayed from the water outlet of the hydraulic pump 17 will always fall into the liquid storage cover 19 and then be sprayed out through the spray pipe 20 to reduce the temperature generated during processing.

[0035] The adsorption assembly includes a fan 22 installed on the rotating sleeve 12 and an adsorption pipe 21 connected to the fan 22. When the fan 22 is started, it adsorbs the waste gas generated during the processing through the adsorption pipe 21, thus purifying the working environment.

[0036] The angle between the adsorption pipe 21 and the nozzle 20 is 180 degrees, so that the coolant sprayed from the nozzle 20 and the suction generated by the adsorption pipe 21 will not affect each other.

[0037] A filter screen can also be installed on the inner wall of the inlet pipe 18 near the connecting frame 11 to facilitate the removal of impurities contained in the coolant.
