[0020] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

[0021] In the description of this utility model, it should be understood that the terms "center," "lateral," "longitudinal," "front," "rear," "left," "right," "upper," "lower," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this utility model.

The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only.

[0022] like Figures 1 to 6 As shown, the present invention relates to a cutting machine tool for mold processing, comprising: a machine tool body 100, a collection box 200, a connecting pipe, and a recycling tank 300. The machine tool body 100 is preferably a wire EDM machine tool. Wire EDM machines have low processing precision and low requirements for the working fluid; therefore, the working fluid can be reused after filtration and cooling. The collection box 200 is used to collect the working fluid during processing. The upper end of the collection box 200 has an opening, and the collection box 200 is located below the fixture. The working fluid falling during cutting falls into the collection box 200. The connecting pipe connects the collection box 200 to the recycling tank 300, which filters and cools the working fluid.

[0023] The machine tool body 100 consists of a base, a first moving mechanism 101, a second moving mechanism 102 mounted on the base, a third moving mechanism 103 mounted on the first moving mechanism 101, a collection box 200 mounted on the third moving mechanism 103, and a cutting head mounted on the second moving mechanism 102.

[0024] In this application, the first moving mechanism 101, the second moving mechanism 102 and the third moving mechanism 103 have the same structure. This application only describes the first moving mechanism 101 as an example. The second moving mechanism 102 and the third moving mechanism 103 can be adapted by referring to the first moving mechanism 101.

[0025] The first moving mechanism 101 includes a threaded rod 1011, a slider 1012, a moving plate 1013, and a guide assembly 1014. One end of the threaded rod 1011 is connected to a handwheel. The slider 1012 is threadedly connected to the threaded rod 1011, so that when the threaded rod 1011 rotates, it can drive the slider 1012 to move on it. The slider 1012 is fixedly connected to the moving plate 1013, and the movement of the slider 1012 can drive the movement of the moving plate 1013. The guide assembly 1014 is preferably a slide rail and a positioning block. The slide rail is mounted on the base, and the positioning block is mounted on the moving plate 1013.

[0026] In one embodiment, the regeneration box 300 includes: a box body 301, a pump body 302, a filter assembly, and a cooling assembly installed inside the box body 301; a fan 303 is installed at the upper end of the box body 301, and the fan 303 draws air outward, thereby cooling the pump body 302, the filter assembly, and the cooling assembly inside the box body 301.

[0027] The pump body 302 is connected to the connecting pipe and is used to pump the working fluid in the collection box 200 into the regeneration tank 300; the cooling assembly consists of a heat exchange tank 304, a compressor 305, and a condenser 306. The heat exchange tank 304 is used for heat exchange, the compressor 305 pumps the coolant into the heat exchange tank, and the condenser 306 is used to cool the coolant after heat exchange.

[0028] It should be noted that the coolant is R134a, the coolant flows inside a copper pipe, and an expansion valve needs to be connected to the copper pipe.

[0029] After the filter assembly removes impurities, it enters the heat exchange tank, and after heat exchange, it flows back to the machine tool body 100.

[0030] In this invention, the filtration assembly includes a housing 307, a magnetic roller 308, and a filter screen 309. The working fluid enters the housing 307, passes through the magnetic roller 308 to remove iron impurities, and then flows into the heat exchange tube after being filtered by the filter screen 309.

[0031] The magnetic roller 308 is connected to a motor 310 that drives its rotation. A scraper 311 is provided on one side of the magnetic roller 308. The scraper 311 is fixedly installed on the box body 307 and is used to scrape off iron impurities on the magnetic roller 308. In one application scenario, the scraper 311 is inclined. A partition 312 is fixedly installed on the box body 307, so that one side of the partition 312 is a collection area and the other side is a filtration area. The impurities in the collection area are relatively concentrated. A discharge pipe can be installed on the box body 307 to discharge the impurities in the collection area.

[0032] The inclined scraper 311 can guide impurities to the collection area, so the filter screen 309 can also be inclined, and through holes are opened in the partition 312 so that impurities on the surface of the filter screen 309 can reach the collection area.

[0033] In one embodiment, the shaft of the motor 310 is connected to the magnetic roller 308. A rotating wheel 313 is fixedly mounted on the shaft of the motor 310. A protrusion 314 is integrally connected to the rotating wheel 313. An elastic element 315 is provided below the filter screen 309. When the motor 310 drives the magnetic roller 308 to rotate, it will synchronously drive the rotating wheel 313 to rotate. The rotating wheel 313 will push the filter screen 309 downward, causing the elastic element 315 to move downward under force. Then the elastic element 315 will push the filter screen 309 back, thereby causing the filter screen 309 to vibrate up and down, thereby accelerating the movement speed of impurities.

[0034] It should be explained here that the angle of the filter screen 309 should be relatively large so that a suitable proportion of working fluid flows into the collection area, so that impurities in the collection area can flow away.

[0035] The elastic element 315 is preferably a spring, which is sleeved on the guide rod 316, and the guide rod 316 is fixedly connected to the filter screen 309.

[0036] In one embodiment, a guide plate 317 is fixedly installed inside the box 307. The guide plate 317 guides the working fluid to the magnetic roller 308. The lower end of the guide plate 317 is a horizontal section, which facilitates the magnetic roller 308 to adsorb iron impurities.

[0037] Working principle: After the working fluid is filtered by the filter assembly to remove impurities, it enters the heat exchange tank. After heat exchange, it flows back into the machine tool body 100, thus realizing the regeneration of the working fluid.

[0038] All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here. The contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0039] It should be understood that those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
