Detailed implementation manners

[0035] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0036] Example 1, please refer to Figures 1-12The present invention discloses a casting device for the bottom flange of a washing machine barrel, which includes 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. The other ends of the second hydraulic rods 23 are fixedly connected with a fixed ring 3. Through the design of the two second hydraulic rods 23, the fixation of the fixed ring 3 can be more stable, preventing the fixed ring 3 from shaking when the subsequent second hydraulic rods 23 drive the fixed ring 3 to slide. The fixed ring 3 is rotatably connected with a rotating ring 4. It should be noted that the fixed ring 3 and the rotating ring 4 will not separate. Above the fixed ring 3, there is an intermittent gear 31. In the middle of the fixed ring 3, a plurality of filter plates 32 are rotatably connected. Fixed blocks 33 are fixedly connected to the filter plates 32. An arc ring 34 is rotatably connected to the fixed blocks 33. On the rotating shaft of the middle filter plate 32, a first half gear 35 is fixedly connected. 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. 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 abuts against one side of the protruding rod 36. Through the design of the first torsion spring 37, the first half gear 35 and the filter plates 32 can be driven to be in a vertical state as much as possible, preventing the filter plates 32 from closing when the fixed ring 3 drives the filter plates 32 to slide into the interior of the filter cylinder 2.

[0037] At the lower end of the control rod 24, there is a rack 25. One side of the rack 25 is meshed with the first half gear 35. Through the design that the first half gear 35 has less than half of the gear, when the first half gear 35 rotates a very small angle, each filter plate 32 can be flattened and aligned, so that when the fixed ring 3 and the rotating ring 4 slide out of the filter cylinder 2, the filter plates 32 can quickly be in a flattened state, enabling the filter plates 32 to quickly enter the working state.

[0038] First, the raw materials are fed into the melting device 11 through the feeding device 1. The raw materials are melted into molten aluminum by the melting device 11. Subsequently, the molten aluminum is transferred into the filter cylinder 2 for filtering the molten aluminum. Then, the second hydraulic rods 23 are started, so that the second hydraulic rods 23 drive the fixed ring 3 and the rotating ring 4 to gradually slide into the interior of the filter cylinder 2, as shown in 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 interior of the filter cylinder 2, it will not affect the flow of impurities in the molten aluminum, and as much as possible, prevent the impurities in the molten aluminum from being pressed into the interior of the filter cylinder 2; it should be noted that the fixed ring 3 is a Figure 5 circular plate as shown, with a hollow design in the middle.

[0039] It should be noted that, as shown in Figure 8 and Figure 9When the fixed ring 3 drives the filter plate 32, the first half gear 35 and the convex rod 36 to slide downward, the first half gear 35 will also touch the rack 25 but not mesh. The first half gear 35 will touch the rack 25, but when the outermost side tooth of the first half gear 35 collides with the rack 25, the filter plate 32 will be slightly deflected. 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, without affecting the flow of impurities in the molten aluminum.

[0040] In this embodiment: By sliding the vertical filter plate 32 into the filter cylinder 2, it can effectively prevent the filter plate 32 from pressing the impurities in the molten aluminum into the filter cylinder 2 when sliding into the filter cylinder 2. When the fixed ring 3 and the rotating ring 4 slide into the filter cylinder 2, enough flow space can be left for the impurities in the molten aluminum between the filter plates 32, so that when the filter plate 32 slides into the filter cylinder 2, the impurities will not be pressed below the filter plate 32, and the impurities in the molten aluminum can be cleaned more thoroughly.

[0041] Embodiment 2. This embodiment aims to solve the problem that when the fixed ring 3 drives the filter plate 32 to slide into the filter cylinder 2, there is no space for the impurities to flow between the filter plates 32, resulting in the impurities being pressed into the filter cylinder 2. This embodiment is an improvement based on Embodiment 1. Specifically, please refer to Figures 1-12 , a scraping inclined block 41 is arranged above the rotating ring 4. The scraping inclined block 41 is slidably connected to the inner wall of the filter cylinder 2. The scraping inclined block 41 is used to scrape the impurities on the inner wall of the filter cylinder 2. A guiding groove 42 is opened in the middle of the scraping inclined block 41. The guiding groove 42 is used to guide the impurities scraped by the scraping inclined block 41 above the fixed ring 3. By driving the scraping inclined block 41 to rotate inside the filter cylinder 2 through the subsequent rotating ring 4, the scraping inclined block 41 can scrape the impurities on the inner wall of the filter cylinder 2.

[0042] One side of the lower end of the control rod 24 is fixedly connected with a fixed pipe 26. A sliding rod 28 is slidably connected inside the fixed pipe 26. A first spring 27 is arranged between the fixed pipe 26 and the sliding rod 28. The first spring 27 is located inside the fixed pipe 26. The other end of the sliding rod 28 is fixedly connected with a sliding ball 29. Through the design of the first spring 27, the sliding rod 28 can always have a force to slide outward.

[0043] A spiral groove 43 is opened on the inner side of the rotating ring 4. A sliding groove 410 is communicated between the upper end and the lower end of the spiral groove 43. The sliding groove 410 is slidably connected with the sliding rod 28.

[0044] One end of the sliding groove 410 is provided with a smooth groove 44. The other end of the smooth groove 44 communicates with a vertical sliding groove 45. The other end of the vertical sliding groove 45 communicates with an inclined sliding groove 46. The smooth groove 44, the vertical sliding groove 45, the inclined sliding groove 46 and the spiral groove 43 communicate with each other. The sliding ball 29 is slidably connected to the smooth groove 44, the vertical sliding groove 45, the inclined sliding groove 46 and the spiral groove 43;

[0045] When the sliding ball 29 is located in the spiral groove 43, the rotating ring 4 rotates.

[0046] An anti-blocking inclined block 47 is arranged on the inclined sliding groove 46. The anti-blocking inclined block 47 is used to block the inclined sliding groove 46. The anti-blocking inclined block 47 is slidably connected to the inside of the rotating ring 4. The inclined surface of the anti-blocking inclined block 47 is used to contact the sliding ball 29. A second spring 49 is arranged on one side of the anti-blocking inclined block 47. The second spring 49 is located inside the rotating ring 4;

[0047] When the sliding ball 29 contacts the anti-blocking inclined block 47, the anti-blocking inclined block 47 opens the inclined sliding groove 46. Through the design of the anti-blocking inclined block 47, when the sliding ball 29 slides past the anti-blocking inclined block 47 in the inclined sliding groove 46, the sliding ball 29 can be prevented from continuing to slide into the inclined sliding groove 46 by the blocking of the vertical surface of the anti-blocking inclined block 47.

[0048] An empty groove 48 is formed on the anti-blocking inclined block 47. The empty groove 48 is used for slidably connecting with the sliding rod 28. As Figure 7 shown, through such a design, when the sliding ball 29 slides to the right, it can contact the anti-blocking inclined block 47 to open the block of the inclined sliding groove 46. When the sliding ball 29 slides past the anti-blocking inclined block 47, the sliding ball 29 can be prevented from sliding to the left by the contact of the straight surface of the anti-blocking inclined block 47.

[0049] 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 inside of the filter cylinder 2, the sliding ball 29 will first slide in the vertical sliding groove 45. When the sliding ball 29 slides to the inclined sliding groove 46, through the guidance of the inclined surface of the inclined sliding groove 46, the sliding ball 29 will drive the sliding rod 28 to slide into the inside of the fixed tube 26. When the sliding ball 29 slides to the inclined surface of the anti-blocking inclined block 47, by contacting the inclined surface of the anti-blocking inclined block 47 with the sliding ball 29, the anti-blocking inclined block 47 slides into the inside of the rotating ring 4, and at the same time, the second spring 49 is compressed, so that the second spring 49 deforms to provide power for the subsequent reset of the anti-blocking inclined block 47. When the sliding ball 29 slides past the anti-blocking inclined block 47, the anti-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 sliding groove 46. At this time, the sliding ball 29 is at the port of the spiral groove 43;

[0050] After the fixed ring 3 and the rotating ring 4 slide into the interior of the filter cylinder 2 and need to slide out of the interior of the filter cylinder 2, they are pulled by the second hydraulic rod 23, so that the fixed ring 3 and the rotating ring 4 slide upward together. At this time, the sliding ball 29 slides in the spiral groove 43. Under the guidance of the spiral groove 43, the rotating ring 4 rotates. Through the rotation of the rotating ring 4, the scraping inclined block 41 rotates together. Through the rotation of the scraping inclined block 41, the impurities on the inner wall of the filter cylinder 2 are scraped off; when the sliding ball 29 slides to the junction of the spiral groove 43 and the smooth groove 44, under the action of the first spring 27, the sliding rod 28 and the sliding ball 29 are pushed to slide in the smooth groove 44, 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 slid out of the filter cylinder 2.

[0051] 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.

[0052] When the second hydraulic rod 23 pulls the fixed ring 3 and the rotating ring 4 out of the interior of the filter cylinder 2, at this time, the first half gear 35 meshes with the rack 25, so that the first half gear 35 drives the middle filter plate 32 to rotate. Through the rotation of the middle filter plate 32, the fixed block 33 is driven to rotate together. While the fixed block 33 rotates, the arc rings 34 on both sides are driven to rotate together. Through the rotation of the arc rings 34, the fixed blocks 33 on both sides rotate together. Through the transmission of each arc ring 34, the filter plates 32 on both sides can also rotate together, so that each filter plate 32 can be aligned into a complete filter plate. When the molten aluminum passes between the filter plates 32, the impurities in the molten aluminum can be filtered out;

[0053] It should be noted that the transmission structure between the filter plates 32 is the same as the principle of the air outlet of an automotive air conditioner. At the same time, during the meshing of the first half gear 35 with the rack 25, through the design of the first torsion spring 37, after the teeth on the first half gear 35 are all meshed with the rack 25, the first half gear 35 can always reverse. At the same time, under the continuous action of the rack 25, the first half gear 35 can only swing slightly. Such a swing does not affect the filtration of the molten aluminum.

[0054] In this embodiment: When the second hydraulic rod 23 drives the fixed ring 3 and the rotating ring 4 to slide outward of the filter cylinder 2, through the cooperation between the first half gear 35 and the rack 25, each filter plate 32 can be spliced into a complete filter plate, so that when the filter plate 32 slides outward of the filter cylinder 2, impurities in the molten aluminum can be filtered out;

[0055] Moreover, through the cooperation between the sliding ball 29 and the spiral groove 43, the rotating ring 4 can rotate. Through the cooperation between the filter plate 32 and the scraping inclined block 41, impurities in the molten aluminum can be filtered, and at the same time, 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 guiding 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 molten aluminum be filtered more cleanly.

[0056] Embodiment Three aims to solve the problem that when the scraping inclined block 41 scrapes the impurities on the inner wall of the filter cylinder 2, too many impurities will remain on the scraping inclined block 41, affecting the scraping effect of the scraping inclined block 41. This embodiment is an improvement based on Embodiment Two. Specifically, please refer to Figures 1-12 , a second half gear 5 is rotatably connected inside the rotating ring 4. The second half gear 5 is used to engage with the intermittent gear 31. A knocking hammer 52 is arranged on one side of the second half gear 5. The knocking hammer 52 is used to knock the inside of the rotating ring 4. A second torsion spring 51 is sleeved on the rotating shaft of the second half gear 5. One end of the second torsion spring 51 is fixedly connected to the inside of the rotating ring 4, and the other end of the second torsion spring 51 abuts against one side of the knocking hammer 52.

[0057] A first hydraulic rod 21 is fixedly connected above the control disc 22. The other end of the first hydraulic rod 21 is fixedly connected to a mounting plate 12. A filter cylinder 2 is arranged on the mounting plate 12. The filter cylinder 2 is located below the control disc 22. One side of the filter cylinder 2 is connected to a melting device 11 for melting raw materials. The other side of the melting device 11 is provided with a feeding device 1.

[0058] See Figure 5When 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 engage with the intermittent gear 31. Through the engagement of the intermittent gear 31 and the second half gear 5, the second half gear 5 will rotate. While the second half gear 5 rotates, it drives the hammer 52 to rotate together. At the same time, when the second half gear 5 rotates, it can cause the second torsion spring 51 to deform. 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 engaged with the intermittent gear 31, under the action of the second torsion spring 51, the second half gear 5 will rotate back, so that the second half gear 5 drives the hammer 52 to strike the inside of the rotating ring 4. Through the strike of the hammer 52 on the inside of the rotating ring 4, the rotating ring 4 generates vibration, so that the impurities attached to the scraping inclined block 41 can be shaken off.

[0059] It should be noted that after the fixed ring 3 and the rotating ring 4 slide out of the filter cylinder 2, start the first hydraulic rod 21, so that the first hydraulic rod 21 drives the control disc 22, the second hydraulic rod 23, the control rod 24, the fixed ring 3 and the rotating ring 4 to move away from the upper part of the filter cylinder 2, so as to facilitate 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 for each structure of this equipment are all much higher than the melting point of aluminum, and professionals in this field can freely select.

[0060] 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 lowermost end of the vertical chute 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 chute 45 to the upper end of the vertical chute 45. If the sliding ball 29 continues to slide, it will slide into the inclined chute 46. Under the guidance of the inclined chute 46, the sliding ball 29 slides to the junction of the inclined chute 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 later, the sliding ball 29 can only slide in the spiral groove 43, causing the rotating ring 4 to rotate; when the sliding ball 29 slides from the upper end of the spiral groove 43 to the junction of the lower end of the spiral groove 43 and the smooth groove 44, under the action of the first spring 27, the sliding ball 29 will drive the sliding rod 28 and the sliding ball 29 to slide in the smooth groove 44, making the sliding ball 29 slide to the junction of the smooth groove 44 and the vertical chute 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, enabling each filter plate 32 to be butted into a complete filter plate. The first half gear 35 is located in the inner cavity opened in the fixed ring 3. 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.

[0061] 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. While the second half gear 5 rotates, the second torsion spring 51 can be deformed. Thus, after the intermittent gear 31 finishes meshing with the second half gear 5, the second half gear 5 can be quickly rotated back by the force of the second torsion spring 51. Thereby, the second half gear 5 drives the knocking hammer 52 to knock on the inside of the rotating ring 4, causing the rotating ring 4 to vibrate, so that the impurities adhering to the scraping inclined block 41 can be shaken off, and further enabling the impurities in the molten aluminum to be filtered more cleanly.

[0062] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or elements inherent to such process, method, article or device.

[0063] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
