DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] For example, see Figure 1-Figure 12 The present invention discloses a flange casting device for the bottom of a washing machine barrel, comprising a control disc 22, a pair of second hydraulic rods 23 are fixedly connected below the control disc 22, a control rod 24 is arranged between the second hydraulic rods 23, and a fixed ring 3 is fixedly connected to the other end of the second hydraulic rod 23. The design of the two second hydraulic rods 23 makes it possible to fix the fixed ring 3 more stably, so as to prevent the fixed ring 3 from shaking when the subsequent second hydraulic rod 23 drives the fixed ring 3 to slide. The fixed ring 3 is rotatably connected to a rotating ring 4. It should be noted that the fixed ring 3 and the rotating ring 4 will not separate, an intermittent gear 31 is arranged above the fixed ring 3, and the middle of the fixed ring 3 is rotatably connected to There are multiple filter plates 32, each of which is fixedly connected to a fixed block 33, and an arc ring 34 is rotatably connected to the fixed block 33. A first half gear 35 is fixedly connected to the rotating shaft of the middle filter plate 32, and a protruding rod 36 is fixedly connected to the first half gear 35. A first torsion spring 37 is sleeved on the rotating shaft of the first half gear 35, and one end of the first torsion spring 37 is fixedly installed inside the fixed ring 3, and the other end of the first torsion spring 37 is in contact with one side of the protruding rod 36. Through the design of the first torsion spring 37, the first half gear 35 and the filter plate 32 can be driven to be in a vertical state as much as possible, so as to prevent the filter plates 32 from being closed when the fixed ring 3 drives the filter plate 32 to slide into the filter cylinder 2.

[0031] A rack 25 is provided at the lower end of the control rod 24, and one side of the rack 25 is meshed and connected with the first half gear 35. The design of the first half gear 35 having less than half a gear allows the first half gear 35 to rotate at a very small angle to flatten and align the filter plates 32, so that when the fixed ring 3 and the rotating ring 4 slide to the outside of the filter cylinder 2, the filter plates 32 can be quickly flattened, so that the filter plates 32 can quickly enter the working state.

[0032] First, the raw material is fed into the melting device 11 through the feeding device 1, and the raw material is melted into aluminum liquid through the melting device 11, and then the aluminum liquid is transferred to the filtering cylinder 2 for filtering the aluminum liquid. Then, the second hydraulic rod 23 is started, so that the second hydraulic rod 23 drives the fixed ring 3 and the rotating ring 4 to gradually slide into the interior of the filtering cylinder 2. Figure 2 At this time, the filter plates 32 are all in a vertical state, so that when the fixed ring 3 and the rotating ring 4 slide into the inside of the filter cylinder 2, the flow of impurities in the aluminum liquid will not be affected, and the impurities in the aluminum liquid are prevented from being pressed into the inside of the filter cylinder 2 as much as possible; It should be noted that the fixed ring 3 is Figure 5 The circular plate shown has a hollow design in the middle.

[0033] It should be noted that see Figure 8 and Fig. 9 When the fixed ring 3 drives the filter plate 32, the first half gear 35 and the protruding rod 36 to slide downward, the first half gear 35 will also touch the rack 25 but will not mesh with it. The first half gear 35 will touch the rack 25, but the outermost side tooth of the first half gear 35 will collide with the rack 25, causing the filter plate 32 to deflect slightly. Combined with the design of the first torsion spring 37, the first half gear 35 can be reset, so that when the fixed ring 3 and the rotating ring 4 slide into the filter cylinder 2, the filter plate 32 can always be in a relatively vertical state, and will not affect the flow of impurities in the aluminum liquid.

[0034] In the present embodiment, by sliding the vertical filter plate 32 into the interior of the filter cylinder 2, it is possible to effectively prevent the filter plate 32 from pressing impurities in the aluminum liquid into the interior of the filter cylinder 2 when sliding into the filter cylinder 2, so that when the fixed ring 3 and the rotating ring 4 slide into the interior of the filter cylinder 2, sufficient flow space can be left between the filter plates 32 for impurities in the aluminum liquid, so that when the filter plate 32 slides into the interior of the filter cylinder 2, the impurities will not be pressed under the filter plate 32, so that the impurities in the aluminum liquid can be cleaned more thoroughly.

[0035] Embodiment 2: This embodiment is intended to promote the solution of the problem that when the fixed ring 3 slides with the filter plate 32 into the filter cylinder 2, there is no space between the filter plates 32 for impurities to flow, resulting in the impurities being pressed into the filter cylinder 2. This embodiment is an improvement made on the basis of embodiment 1. For details, please refer to Figure 1-Figure 12 A scraping bevel 41 is arranged above the rotating ring 4. The scraping bevel 41 is slidably connected to the inner wall of the filter cylinder 2. The scraping bevel 41 is used to scrape impurities on the inner wall of the filter cylinder 2. A guide groove 42 is opened in the middle of the scraping bevel 41. The guide groove 42 is used to guide the impurities removed by the scraping bevel 41 to the top of the fixed ring 3. The scraping bevel 41 is driven by the subsequent rotating ring 4 to rotate inside the filter cylinder 2, so that the scraping bevel 41 can scrape the impurities on the inner wall of the filter cylinder 2.

[0036] A fixed tube 26 is fixedly connected to one side of the lower end of the control rod 24, and a sliding rod 28 is slidably connected to the inside of the fixed tube 26. A first spring 27 is provided between the fixed tube 26 and the sliding rod 28. The first spring 27 is located inside the fixed tube 26. A sliding ball 29 is fixedly connected to the other end of the sliding rod 28. Through the design of the first spring 27, the sliding rod 28 can always have a force to slide outward.

[0037] A spiral groove 43 is formed on the inner side of the rotating ring 4 . A sliding groove 410 is connected between the upper end and the lower end of the spiral groove 43 . The sliding groove 410 is slidably connected to the sliding rod 28 .

[0038] A smooth groove 44 is provided at one end of the sliding groove 410, the other end of the smooth groove 44 is connected to a vertical sliding groove 45, the other end of the vertical sliding groove 45 is connected to an inclined sliding groove 46, the smooth groove 44, the vertical sliding groove 45, the inclined sliding groove 46 and the spiral groove 43 are connected to each other, and the sliding ball 29 is slidably connected with the smooth groove 44, the vertical sliding groove 45, the inclined sliding groove 46 and the spiral groove 43; When the sliding ball 29 is located in the spiral groove 43, the rotating ring 4 rotates.

[0039] The inclined slide groove 46 is provided with a blocking oblique block 47, which is used to close the inclined slide groove 46, and the blocking oblique block 47 is slidably connected with the inside of the rotating ring 4, and the inclined surface of the blocking oblique block 47 is used to contact the sliding ball 29, and a second spring 49 is provided on one side of the blocking oblique block 47, and the second spring 49 is located inside the rotating ring 4; When the sliding ball 29 collides with the blocking bevel block 47, the blocking bevel block 47 opens the inclined slot 46. Through the design of the blocking bevel block 47, when the sliding ball 29 slides through the blocking bevel block 47 from the inclined slot 46, the vertical surface of the blocking bevel block 47 can prevent the sliding ball 29 from continuing to slide into the inclined slot 46.

[0040] The blocking block 47 is provided with a slot 48, which is used for sliding connection with the sliding rod 28. Figure 7 As shown, through such a design, the sliding ball 29 can contact with the blocking bevel 47 when sliding to the right, so that the blocking bevel 47 opens the blockage of the inclined slide groove 46. When the sliding ball 29 slides over the blocking bevel 47, the sliding ball 29 can be prevented from sliding to the left through the contact with the direct surface of the blocking bevel 47.

[0041] See Figure 6 When the second hydraulic rod 23 drives the fixed ring 3, the rotating ring 4 and the filter plate 32 to slide into the filter cylinder 2, the sliding ball 29 will first slide in the vertical slide groove 45. When the sliding ball 29 slides to the inclined slide groove 46, the sliding ball 29 will drive the sliding rod 28 to slide into the fixed tube 26 through the guidance of the inclined surface of the inclined slide groove 46. When the sliding ball 29 slides to the inclined surface of the blocking inclined block 47, the sliding ball 29 will resist the inclined surface of the blocking inclined block 47, so that the blocking inclined block 47 slides into the rotating ring 4 and squeezes the second spring 49, so that the second spring 49 is deformed to provide power for the subsequent reset of the blocking inclined block 47. After the sliding ball 29 slides over the blocking inclined block 47, the blocking inclined block 47 rebounds under the action of the second spring 49 to prevent the sliding ball 29 from sliding back into the inclined slide groove 46. At this time, the sliding ball 29 is at the end of the spiral groove 43. When the fixed ring 3 and the rotating ring 4 slide into the interior of the filter cylinder 2, when the fixed ring 3 and the rotating ring 4 need to slide out of the interior of the filter cylinder 2, the second hydraulic rod 23 is pulled to make the fixed ring 3 and the rotating ring 4 slide upward together. At this time, the sliding ball 29 will slide in the spiral groove 43. The rotating ring 4 is rotated by the guidance of the spiral groove 43. The scraping inclined block 41 is rotated together by the rotation of the rotating ring 4. The scraping inclined block 41 scrapes the impurities on the inner wall of the filter cylinder 2 by the rotation of the scraping inclined block 41; when the sliding ball 29 slides to the junction of the spiral groove 43 and the smooth groove 44, the sliding rod 28 and the sliding ball 29 are pushed to slide in the smooth groove 44 under the action of the first spring 27, so that the sliding ball 29 slides to the junction of the smooth groove 44 and the vertical sliding groove 45. At this time, the fixed ring 3 and the rotating ring 4 have already slid out of the filter cylinder 2.

[0042] It should be noted that when the sliding ball 29 slides in the vertical sliding groove 45, the sliding rod 28 slides in the sliding groove 410 to prevent the sliding rod 28 and the sliding ball 29 from getting stuck. At the same time, when the sliding ball 29 slides into the inclined sliding groove 46, the sliding rod 28 is located in the empty groove 48 of the blocking inclined block 47 to prevent getting stuck.

[0043] When the second hydraulic rod 23 pulls the fixed circular ring 3 and the rotating ring 4 to slide out of the filter cylinder 2, the first half gear 35 is meshed with the rack 25, so that the first half gear 35 drives the middle filter plate 32 to rotate, and the rotation of the middle filter plate 32 drives the fixed block 33 to rotate together, and the rotation of the fixed block 33 drives the circular arc rings 34 on both sides to rotate together, and the rotation of the circular arc ring 34 makes the fixed blocks 33 on both sides rotate together, and the transmission of each circular arc ring 34 makes the filter plates 32 on both sides rotate together, so that each filter plate 32 can be aligned into a complete filter plate, so that when the aluminum liquid passes between the filter plates 32, the impurities in the aluminum liquid can be filtered out; It should be noted that the transmission structure between the filter plates 32 is the same as the principle of the air outlet of the automobile air conditioner. At the same time, when the first half gear 35 is engaged with the rack 25, the first torsion spring 37 is designed so that after the teeth on the first half gear 35 are engaged with the rack 25, the first half gear 35 can be reversed continuously. At the same time, under the continuous action of the rack 25, the first half gear 35 can only swing very slightly, and such swinging will not affect the filtration of the aluminum liquid.

[0044] In this embodiment: when the second hydraulic rod 23 drives the fixed ring 3 and the rotating ring 4 to slide outside the filter cylinder 2, the first half gear 35 and the rack 25 cooperate to enable the filter plates 32 to be spliced ​​into a complete filter plate, so that the filter plates 32 can filter out impurities in the aluminum liquid when sliding outside the filter cylinder 2; Moreover, through the cooperation between the sliding ball 29 and the spiral groove 43, the rotating ring 4 can rotate, and through the cooperation between the filter plate 32 and the scraping bevel 41, the impurities in the aluminum liquid can be filtered, and the impurities attached to the inner wall of the filter cylinder 2 can also be scraped off. At the same time, through the guidance of the guide groove 42, the impurities scraped off from the inner wall of the filter cylinder 2 can be guided to the fixed ring 3, which can facilitate the subsequent cleaning of the fixed ring 3 and the rotating ring 4 to a certain extent, and further make the impurities in the aluminum liquid be filtered more cleanly.

[0045] Embodiment 3: This embodiment is intended to promote the solution of the problem that when the scraping inclined block 41 scrapes impurities on the inner wall of the filter cylinder 2, too much impurities will remain on the scraping inclined block 41, affecting the scraping effect of the scraping inclined block 41. This embodiment is an improvement made on the basis of embodiment 2. For details, please refer to Figure 1-Figure 12The interior of the rotating ring 4 is rotatably connected with a second half gear 5, and the second half gear 5 is used to mesh with the intermittent gear 31. A knock hammer 52 is provided on one side of the second half gear 5, and the knock hammer 52 is used to knock the interior of the rotating ring 4. A second torsion spring 51 is sleeved on the rotating shaft of the second half gear 5, and one end of the second torsion spring 51 is fixedly connected to the interior of the rotating ring 4, and the other end of the second torsion spring 51 contacts one side of the knock hammer 52.

[0046] A first hydraulic rod 21 is fixedly connected to the top of the control disc 22, and a mounting plate 12 is fixedly connected to the other end of the first hydraulic rod 21. A filter cylinder 2 is arranged on the mounting plate 12, and the filter cylinder 2 is located below the control disc 22. A melting device 11 for melting raw materials is connected to one side of the filter cylinder 2, and a feeding device 1 is arranged on the other side of the melting device 11.

[0047] See Figure 5 When the rotating ring 4 rotates, it can drive the second half gear 5 to rotate together. When the second half gear 5 rotates to the intermittent gear 31, the second half gear 5 will mesh with the intermittent gear 31. Through the meshing of the intermittent gear 31 and the second half gear 5, the second half gear 5 will rotate. When the second half gear 5 rotates, it drives the knocking hammer 52 to rotate together. At the same time, when the second half gear 5 rotates, the second torsion spring 51 can be deformed. Through the deformation of the second torsion spring 51, the second half gear 5 has a power to reset. When the second half gear 5 passes the position of the intermittent gear 31 and the second half gear 5 is not meshed with the intermittent gear 31, the second half gear 5 will rotate under the action of the second torsion spring 51, so that the second half gear 5 drives the knocking hammer 52 to knock the inside of the rotating ring 4. Through the knocking of the knocking hammer 52 on the inside of the rotating ring 4, the rotating ring 4 vibrates, so that the impurities attached to the scraping inclined block 41 can be shaken off.

[0048] It should be noted that, after the fixed ring 3 and the rotating ring 4 slide out of the filter cylinder 2, the first hydraulic rod 21 is started, so that the first hydraulic rod 21 drives the control disk 22, the second hydraulic rod 23, the control rod 24, the fixed ring 3 and the rotating ring 4 to be removed from the top of the filter cylinder 2, thereby facilitating the cleaning of the fixed ring 3 and the rotating ring 4. During the cleaning process, the fixed ring 3 and the rotating ring 4 can be heated to facilitate the cleaning of the aluminum liquid solidified on the fixed ring 3 and the rotating ring 4. At the same time, the materials used in each structure of the equipment are far higher than the melting point of aluminum, and professionals in this field can freely select them.

[0049] When the second hydraulic rod 23 drives the fixed ring 3 and the rotating ring 4 to slide downward, the sliding ball 29 is at the lowest end of the vertical slide groove 45. As the fixed ring 3 and the rotating ring 4 slide downward, the sliding ball 29 will gradually slide from the lower end of the vertical slide groove 45 to the upper end of the vertical slide groove 45. The sliding ball 29 continues to slide and slides into the inclined slide groove 46. Under the guidance of the inclined slide groove 46, the sliding ball 29 slides to the intersection of the inclined slide groove 46 and the spiral groove 43. At the same time, under the restriction of the blocking inclined block 47, when the fixed ring 3 and the rotating ring 4 are pulled upward, the sliding ball 29 can only slide in the spiral groove 43, so that the rotating ring 4 rotates; when the sliding ball 29 slides from the upper end of the spiral groove 43 to the intersection of the lower end of the spiral groove 43 and the smooth groove 44 When at the intersection, the sliding ball 29, under the action of the first spring 27, will drive the sliding rod 28 and the sliding ball 29 to slide in the smooth groove 44, so that the sliding ball 29 slides to the intersection of the smooth groove 44 and the vertical sliding groove 45. It should be noted that the upper end of the control rod 24 is fixedly installed on the lower side of the control disc 22, so that the position of the control rod 24 will not slide or shift, and the lower end of the control rod 24 will not penetrate the fixed ring 3. At the same time, when the fixed ring 3 and the rotating ring 4 slide upward, the first half gear 35 rotates, so that each filter plate 32 can be connected to form a complete filter plate, and the first half gear 35 is located in the inner cavity opened inside the fixed ring 3, and at the same time, one end of the first torsion spring 37 is fixedly connected to the side wall of the inner cavity of the fixed ring 3.

[0050] In this embodiment: through the cooperation between the intermittent gear 31 and the second half gear 5, the second half gear 5 can drive the knocking hammer 52 to rotate, and the second half gear 5 can deform while rotating, so that after the intermittent gear 31 is engaged with the second half gear 5, the second half gear 5 can be driven by the force of the second torsion spring 51 to rotate quickly, so that the second half gear 5 drives the knocking hammer 52 to knock on the inside of the rotating ring 4, so that the rotating ring 4 can vibrate, so that the impurities attached to the scraper bevel block 41 can be shaken off, and further the impurities in the aluminum liquid can be filtered more cleanly.

[0051] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0052] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
