[0002] A die-casting machine is an industrial casting machine that hydraulically injects molten metal into a mold under pressure, cools it and forms it, and then obtains a solid metal casting after the mold is opened.

[0003] The existing die-casting machine hydraulic oil filtration device is divided into two processes: coarse filtration and fine filtration. In the coarse filtration stage, the main purpose is to filter out large particles. However, these large particles tend to adhere to the surface of the filter element. Over time, the filtration efficiency of the filter element will be significantly reduced, thereby affecting the performance of the entire filtration system. Utility Model Content

[0004] Based on this, the purpose of the utility model is to provide a hydraulic oil filter device for a die-casting machine to solve the technical problem that large particles tend to adhere to the surface of the filter element.

[0006] By adopting the above technical solution, when the hydraulic oil enters from the oil inlet, it will drive the driving fan to rotate, and then drive the scraper to continuously scrape the surface of the filter element. The large particles of impurities attached to the filter element will be scraped off, thereby avoiding impurities clogging the filter element and ensuring the filtering effect.

[0007] Furthermore, a collecting groove is provided on one side of the bottom of the coarse filter cartridge, and a sliding groove is provided on one side of the collecting groove.

[0008] By adopting the above technical solution, the collection groove opened on one side of the bottom of the coarse filter cartridge can effectively collect large particles of impurities scraped off by the scraper. Since these impurities will adhere to the filter element during the filtration process, affecting the filtration effect and may even cause the filter element to be blocked, if they are not collected in time, they may block the oil inlet and affect the oil inlet efficiency.

[0009] Furthermore, the interior of the sliding groove is slidably connected to a partition plate, and a sealing strip is provided between the partition plate and the coarse filter cartridge.

[0010] By adopting the above technical solution, the partition plate slidably connected inside the sliding groove can flexibly control the connection state between the collection groove and the coarse filter cylinder. When the partition plate is in the closed position, it can effectively prevent the hydraulic oil from flowing out, thereby ensuring that the large particles of impurities collected in the collection groove can be cleaned and reducing the loss of oil.

[0011] Furthermore, a handle is fixedly connected to one side of the partition plate, and two sealing strips are provided, and the two sealing strips are arranged in a mirror image structure.

[0012] By adopting the above technical solution, the handle fixedly connected to one side of the partition plate provides convenience for the operator.

[0015] Furthermore, a plurality of the oil outlets are provided, and the plurality of the oil outlets are evenly arranged in a ring shape along the center line of the oil outlet plate.

[0016] By adopting the above technical solution, multiple oil outlets are evenly arranged in a ring shape along the center line of the oil outlet plate, which increases the distribution area and uniformity of the hydraulic oil when it flows out of the scraper mechanism, so that it enters the coarse filter cartridge more quickly and improves the filtration efficiency.

[0017] Furthermore, an oil inlet pipe is fixedly connected to the bottom of the coarse filter cartridge, and an end of the oil inlet pipe is fixedly connected to an oil pump.

[0018] By adopting the above technical solution, the oil inlet pipe fixedly connected to the bottom of the coarse filter cartridge provides a channel for the hydraulic oil to enter the filter device, ensuring that the hydraulic oil can smoothly enter the coarse filter cartridge for filtration under the drive of the oil pump, thereby ensuring the normal operation of the filter device.

[0019] Furthermore, a fine filter cartridge is provided on one side of the coarse filter cartridge, the fine filter cartridge and the coarse filter cartridge are connected via an oil pipe, and a cartridge cover is provided on the top of the coarse filter cartridge.

[0020] By adopting the above technical solution, the hydraulic oil after preliminary filtration by the coarse filter cartridge can enter the fine filter cartridge for finer filtration, thereby removing smaller impurity particles and improving the cleanliness of the hydraulic oil.

[0021] Furthermore, a fixing rod is rotatably connected inside the upper fixing block, a filter element is fixedly connected to the bottom of the fixing rod, and the fixing rod is engaged with the cylinder cover.

[0022] By adopting the above technical solution, the fixed rod rotatably connected inside the upper fixed block provides stable support for the filter element, and the bottom of the fixed rod is fixedly connected to the filter element, ensuring the stability and reliability of the filter element during the filtration process. When the hydraulic oil flows through the filter element, the filter element can effectively intercept and adsorb impurities to ensure the cleanliness of the hydraulic oil.

[0023] Furthermore, a scraper blade is fixedly connected to the inner wall of the scraper plate, and a plurality of scrapers are provided, and the plurality of scrapers are evenly arranged at equal distances.

[0024] By adopting the above technical solution, the provision of the scraper increases the contact area between the scraper and the filter element, thereby improving the scraping effect. When the scraper scrapes on the surface of the filter element, multiple scrapers can act simultaneously to quickly scrape off impurities.

[0025] In summary, the utility model mainly has the following beneficial effects:

[0026] 1. The utility model realizes the effect of automatically scraping off large particles of pollutants by arranging a coarse filter cartridge and a scraper mechanism, which realizes the effect of using the pressure of the incoming oil to drive the scraper, and then automatically scraping off large particles of pollutants. It not only maintains high-efficiency filtration for a long time, but also reduces the frequency of manual intervention and reduces maintenance costs;

[0027] 2. The utility model is provided with a collecting tank and a partition plate. When a certain amount of pollutants accumulate in the collecting tank, the operator can control the connection state between the collecting tank and the coarse filter cartridge by moving the partition plate.

DETAILED DESCRIPTION

[0034] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0035] The following describes an embodiment of the utility model based on its overall structure.

[0036] Embodiment 1:

[0037] A hydraulic oil filter device for a die casting machine, such as Figure 1-Figure 4 As shown, it includes a coarse filter cartridge 1, and a scraper mechanism 2 is arranged inside the coarse filter cartridge 1. The scraper mechanism 2 includes an upper fixed block 201 and a lower fixed block 202, and a scraper 203 is arranged between the upper fixed block 201 and the lower fixed block 202. The bottom of the lower fixed block 202 is fixedly connected with an oil outlet plate 204, and an oil outlet port 207 is provided on the oil outlet plate 204. An oil inlet 205 is provided at the bottom of the oil outlet plate 204, and a driving fan 206 is fixedly connected inside the oil inlet 205. When hydraulic oil enters from the oil inlet 205, the driving fan 206 is driven to rotate, thereby driving the scraper 203 to continuously scrape the surface of the filter element, and large particles of impurities attached to the filter element will be scraped off, thereby avoiding impurities clogging the filter element and ensuring the filtering effect. At the same time, the spiral scraper 203 can continuously push the scraped particles along the spiral trajectory into the subsequent collecting tank 3, so as to realize the reliable recovery of the impurity particles.

[0038] See also Figure 2A collecting groove 3 is provided on one side of the bottom of the coarse filter cartridge 1, and a sliding groove 4 is provided on one side of the collecting groove 3. The collecting groove 3 provided on one side of the bottom of the coarse filter cartridge 1 can effectively collect large particles of impurities scraped off by the scraper 203. Since these impurities will adhere to the filter element during the filtration process, affecting the filtration effect and may even cause the filter element to be blocked, if they are not collected in time, they may block the oil inlet 205 and affect the oil inlet efficiency. At the same time, the partition plate 5 can slide freely in the sliding groove 4, so as to control the connection and separation between the collecting groove 3 and the inside of the coarse filter cartridge 1. When it is necessary to clean the impurities in the collecting groove 3, it is only necessary to move the partition plate 5 to discharge the impurities from the inside of the coarse filter cartridge 1, and the operation is simple and convenient.

[0039] See also Figure 2 The partition plate 5 is connected to the sliding groove 4 internally, and a sealing strip 6 is arranged between the partition plate 5 and the coarse filter cartridge 1. The partition plate 5 connected to the sliding groove 4 internally can flexibly control the communication state between the collecting groove 3 and the coarse filter cartridge 1. When the partition plate 5 is in the closed position, it can effectively prevent the hydraulic oil from flowing out, thereby ensuring that the large particles of impurities collected in the collecting groove 3 can be cleaned up and the loss of oil can be reduced. At the same time, the sealing strip 6 arranged between the partition plate 5 and the coarse filter cartridge 1 enhances the sealing performance between the two, and can effectively prevent the hydraulic oil from leaking in the gap between the partition plate 5 and the coarse filter cartridge 1, thereby ensuring the filtering effect and overall performance of the filtering device.

[0040] See also Figure 1 and Figure 2 A handle 7 is fixedly connected to one side of the partition plate 5, and two sealing strips 6 are provided. The two sealing strips 6 are arranged in a mirror structure. The handle 7 fixedly connected to one side of the partition plate 5 provides convenience for the operator. The setting of the handle 7 makes it easier for the operator to hold and move the partition plate 5, so as to control the connection and disconnection between the collecting tank 3 and the coarse filter cartridge 1. At the same time, the two sealing strips 6 are arranged in a mirror structure between the partition plate 5 and the coarse filter cartridge 1, which further enhances the sealing performance. The mirror structure enables the sealing strip 6 to fit more closely on the contact surface of the partition plate 5 and the coarse filter cartridge 1, effectively preventing the hydraulic oil from leaking out of the gap.

[0041] See also Figure 1 and Figure 2 A discharge pipe 8 is fixedly connected to the bottom of the collecting tank 3, and a faucet 9 is fixedly connected to one end of the discharge pipe 8. The discharge pipe 8 fixedly connected to the bottom of the collecting tank 3 provides a channel for the discharge of impurities. When enough impurities accumulate in the collecting tank 3, the operator can quickly and effectively discharge the impurities from the filtering device through the discharge pipe 8, thereby avoiding the long-term retention and accumulation of impurities inside the device. At the same time, the faucet 9 fixedly connected to one end of the discharge pipe 8 provides a control means for the discharge of impurities. The operator can control the discharge timing and discharge amount of impurities by opening or closing the faucet 9.

[0042] See also Figure 2 and Figure 3 There are multiple oil outlets 207, and the multiple oil outlets 207 are evenly arranged in a ring shape along the center line of the oil outlet plate 204. The multiple oil outlets 207 are evenly arranged in a ring shape along the center line of the oil outlet plate 204, which increases the distribution area and uniformity of the hydraulic oil when it flows out of the scraper mechanism 2, so that it enters the coarse filter cartridge 1 more quickly, thereby improving the filtration efficiency. At the same time, the provision of multiple oil outlets 207 also helps to reduce the flow pressure of a single oil outlet, avoids excessive stress caused by excessive flow, ensures the stability and reliability of the filtering device, and extends its service life.

[0043] See also Figure 1 and Figure 2 An oil inlet pipe 10 is fixedly connected to the bottom of the coarse filter cartridge 1, and an oil pump 11 is fixedly connected to one end of the oil inlet pipe 10. The oil inlet pipe 10 fixedly connected to the bottom of the coarse filter cartridge 1 provides a channel for the hydraulic oil to enter the filtering device, ensuring that the hydraulic oil can smoothly enter the coarse filter cartridge 1 for filtration under the drive of the oil pump 11, thereby ensuring the normal operation of the filtering device. At the same time, the setting of the oil pump 11 not only provides power for the hydraulic oil, but also can control the flow and pressure of the hydraulic oil by adjusting the working state of the oil pump 11, so that the filtering device can adapt to the filtering needs under different working conditions, thereby improving its flexibility and practicality.

[0044] See also Figure 1 and Figure 2 A fine filter cartridge 12 is arranged on one side of the coarse filter cartridge 1. The fine filter cartridge 12 and the coarse filter cartridge 1 are connected by an oil pipe. A cartridge cover 15 is arranged on the top of the coarse filter cartridge 1. The hydraulic oil after preliminary filtration by the coarse filter cartridge 1 can enter the fine filter cartridge 12 for finer filtration, thereby removing smaller impurity particles and improving the cleanliness of the hydraulic oil. At the same time, the fine filter cartridge 12 and the coarse filter cartridge 1 are connected by an oil pipe, so that the two filter cartridges can work together to form a complete filtering system, ensuring the continuity and stability of the filtering process.

[0045] See also Figure 3 The upper fixed block 201 is internally rotatably connected with a fixing rod 14, and the bottom of the fixing rod 14 is fixedly connected with a filter element. The fixing rod 14 and the cylinder cover 15 are engaged with each other. The fixing rod 14 rotatably connected inside the upper fixed block 201 provides a stable support for the filter element, and the bottom of the fixing rod 14 is fixedly connected with the filter element, ensuring the stability and reliability of the filter element during the filtering process. When the hydraulic oil flows through the filter element, the filter element can effectively intercept and adsorb impurities to ensure the cleanliness of the hydraulic oil. At the same time, the design of the fixing rod 14 and the cylinder cover 15 engaging with each other not only facilitates the installation and disassembly of the filter element, but also ensures that the rotation of the upper fixed block 201 will not affect the filter element, thereby improving the reliability of filtering.

[0046] The implementation principle of the utility model is as follows: first, pull open the partition plate 5 and start the oil pump 11. When the oil to be filtered enters the oil inlet 205 from the inside of the oil pump 11 through the oil inlet pipe 10, the driving fan 206 is driven to rotate, and then the spiral scraper 203 is driven to rotate continuously, and the large particles of debris on the filter element are continuously scraped off. The oil passing through the driving fan 206 then enters the inside of the coarse filter cartridge 1 through the oil outlet 207 and is continuously filtered from the filter element.

[0047] The scraped large particles of debris continue to settle downward along the spiral of the scraper 230 and are swept into the interior of the collecting tank 3. When there are a lot of impurities collected in the collecting tank 3, hold the handle 7 to push the partition plate 5 to separate the interior of the collecting tank 3 and the coarse filter cartridge 1, then turn on the faucet 9, and the impurities will flow out through the discharge pipe 8 and the faucet 9, realizing a simple cleaning operation.
