Abstract
Description
Technical Field
[0001] This invention relates to the field of ceramic component molding, specifically to a ceramic component molding equipment for manufacturing butterfly valves. Background Technology
[0002] A butterfly valve is a quick-acting industrial valve that typically controls the flow of liquid in a pipeline by rotating a disc inside the valve body to achieve opening, closing, or flow regulation. To reduce the wear and tear caused by liquid erosion and corrosion inside the butterfly valve, a ceramic valve seat ring is installed inside. The ceramic valve seat ring is partially formed by dry pressing in molds during production.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.
[0021] Example 1: like Figure 1-11 As shown, this embodiment of the invention provides a ceramic component molding device for manufacturing butterfly valves, including a mounting box 1 and a lower mold 2; the lower mold 2 is installed inside one end of the mounting box 1; a support sleeve 10 is provided on the bottom surface of the lower mold 2; a striking mechanism 4 is provided on the outer side of the lower mold 2, and the striking mechanism 4 cooperates with the support sleeve 10 and the mounting box 1; the lower mold 2 is in contact with the top surface of the support sleeve 10. The support sleeve 10 is equipped with a pusher mechanism 3, and the pusher mechanism 3 cooperates with the lower mold 2; A filling mechanism 6 is provided on the outside of the mounting box 1; a pressing mechanism 5 is provided above the lower mold 2, and the pressing mechanism 5 cooperates with the mounting box 1; an infrared sensor 9 is fixedly installed at one end of the mounting box 1 near the lower mold 2, and the infrared sensor 9 is electrically cooperated with the striking mechanism 4.
[0022] In the above process, by having the striking mechanism 4 strike the lower mold 2 with uniform force from all directions, the glass powder is made to be more compact inside the cavity of the lower mold 2, which greatly improves the quality of the die-cast ceramic valve seat ring. By having the pushing mechanism 3 move to the lower mold 2 and push the ceramic powder to the cavity of the lower mold 2, the ceramic powder falls and fills the cavity. After the lower pressing mechanism 5 has formed the die, the pushing mechanism 3 pushes it out for easy removal.
[0023] The striking mechanism 4 includes an outer gear disc 401, a sliding groove 402, a mounting plate 403, a contact wheel 404, a setting sleeve 405, a striking block 406, a rotating column 407, a sliding block 408, a setting block 409, a push spring 410, a rotating gear 411, a limiting ring 412, a contact assembly 413, and a drive assembly 414; the outer gear disc 401 is rotatably connected to the upper outer surface of the support sleeve 10; the sliding groove 402 is formed on the upper surface of the outer gear disc 401, and there are several sliding grooves 402 evenly distributed; the sliding block 408 is slidably connected to the inner side of the sliding groove 402.
[0024] In the above, by setting a number of sliding grooves 402, multiple striking blocks 406 can be set around the lower mold 2 to strike it multiple times simultaneously.
[0025] The rotating column 407 is rotatably connected to the inside of the sliding block 408 near the center of the outer gear disk 401; the setting sleeve 405 is fixedly sleeved on the outer side of the upper end of the rotating column 407; a threaded spring is fixedly connected to the outer surface of the setting sleeve 405, and the striking block 406 is fixedly connected to the end of the threaded spring away from the setting sleeve 405; the rotating gear 411 is fixedly sleeved on the outer side of the lower end of the rotating column 407; the limiting ring 412 is fixed on the upper and lower sides of the rotating gear 411, and the limiting ring 412 is rotatably connected to the rotating column 407; the contact component 413 is set on the outer side of the support sleeve 10 and cooperates with the rotating gear 411; the drive component 414 is set on the inner top surface of the mounting box 1 and cooperates with the outer gear disk 401.
[0026] In the above, by setting a threaded spring to cooperate with the striking block 406, when the striking block 406 strikes the lower mold 2 during rotation, the threaded spring allows the striking block 406 to disengage from the lower mold 2 through its elasticity, reducing the problem of jamming after striking.
[0027] Mounting plate 403 is disposed outside mounting sleeve 405, and the inner side of mounting plate 403 near mounting sleeve 405 is rotatably connected to the outer surface of rotating column 407; mounting block 409 is fixed to the bottom surface of mounting plate 403 away from mounting sleeve 405; the lower end of mounting block 409 is fixed to the upper surface of sliding block 408; push spring 410 is disposed inside sliding groove 402, and the two ends of push spring 410 are fixed to the sliding groove 402 and the side of sliding block 408 away from the center of outer gear disk 401, respectively; contact wheel 404 is rotatably connected to the end of mounting plate 403 near outer gear disk 401.
[0028] In the above, through the cooperation between the mounting plate 403 and the rotating column 407, the mounting plate 403 further limits the rotating column 407, making the rotation of the mounting sleeve 405 driven by the rotating column 407 more stable.
[0029] The contact assembly 413 includes a fixed plate 41301, a limiting groove 41302, a pushing block 41303, a limiting rod 41304, a fixing block 41305, and an internal toothed belt 41306; the fixed plate 41301 is fixedly sleeved on the outside of the support sleeve 10; the limiting groove 41302 is formed on the upper surface of the fixed plate 41301, and there are several limiting grooves 41302 evenly distributed; the pushing block 41303 is slidably connected to the inner side of the limiting groove 41302; the fixing block 41305 is fixedly connected to the top surface of the pushing block 41303; the internal toothed belt 41... 306 is positioned above the fixed disk 41301, and the rotating gear 411 is meshed with the inner surface of the inner toothed belt 41306; the fixed block 41305 is fixedly connected to the outer surface of the inner toothed belt 41306; the limiting rod 41304 is slidably connected inside the pushing block 41303, and both ends of the limiting rod 41304 are fixedly connected to the inner side of the limiting groove 41302; a helical spring is sleeved on the outer side of the limiting rod 41304, and both ends of the helical spring are fixedly connected to the pushing block 41303 and the side of the limiting groove 41302 away from the inner toothed belt 41306, respectively.
[0030] In the above, a helical spring is set to push the push block 41303 toward the center of the fixed disk 41301 through elasticity, thereby tightening the internal toothed belt 41306 to ensure contact and engagement with the rotating gear 411.
[0031] The drive assembly 414 includes a drive gear 41401, a drive motor 41402, and a limiting ring 41403. The drive motor 41402 is fixedly mounted on the inner top surface of the mounting box 1. The inner center of the drive gear 41401 is fixedly connected to the output end of the drive motor 41402, and the drive gear 41401 meshes with the outer gear disk 401. The limiting ring 41403 is fixedly connected to the upper and lower sides of the drive gear 41401 and is fixedly connected to the output shaft of the drive motor 41402. The side of the limiting ring 41403 that is close to each other is in contact with the surface of the outer gear disk 401. The infrared sensor 9 is electrically connected to the drive motor 41402.
[0032] In the above, by setting an infrared sensor 9, the drive motor 41402 is automatically started after the infrared sensor 9 senses the signal, and automatic driving is performed.
[0033] The packing mechanism 6 includes a packing box 601, a connecting rod 602, a moving plate 603, a base 604, a lead screw 605, a stepper motor 606, and a flip cover 607; a limiting frame 8 is fixedly connected to the top surface of the mounting box 1; the packing box 601 slides inside the limiting frame 8, and the bottom end of the packing box 601 contacts the top surface of the mounting box 1; the base 604 is fixedly connected to the bottom surface of the mounting box 1; the moving plate 603 is slidably connected to the inside of the base 604; the connecting rod 602 is distributed on both sides of one end of the packing box 601; the two ends of the connecting rod 602 are fixedly connected to the surface of the packing box 601 and the end of the moving plate 603, respectively.
[0034] In the above, by setting the bottom end of the packing box 601 to contact the top surface of the mounting box 1, the problem of glass powder leaking out of the packing box 601 is reduced.
[0035] The lead screw 605 is rotatably connected to the inside of the base 604 and is threadedly connected to the inside of the moving plate 603; the stepper motor 606 is fixedly installed inside the base 604, and the output end of the stepper motor 606 passes through the base 604 and is fixedly connected to one end of the lead screw 605; a circular groove is provided on the top surface of the filling box 601; the flip cover 607 is hinged to the upper surface of the filling box 601 near the circular groove; a feeding plate 7 is fixedly installed on the side of the mounting box 1 away from the stepper motor 606.
[0036] In the above, by setting the lead screw 605 to cooperate with the moving plate 603, the lead screw 605 limits the moving plate 603, making the moving plate 603 move more stably.
[0037] The pushing mechanism 3 includes a pushing cylinder 301, a pushing disc 302, a pushing ring 303, and a connecting rod 304. The pushing cylinder 301 is fixedly installed on the bottom surface of the mounting box 1. The pushing disc 302 is slidably connected to the inner side of the support sleeve 10, and its bottom surface is fixedly connected to the telescopic end of the pushing cylinder 301. The pushing ring 303 is disposed inside the lower mold 2 and fits into the cavity of the lower mold 2. The connecting rod 304 is fixedly connected to the bottom surface of the pushing ring 303, and the connecting rod 304 passes through the lower mold 2 and is fixedly connected to the top surface of the pushing disc 302.
[0038] In the above, the pusher ring 303 fits into the cavity of the lower mold 2, thereby reducing the problem of the pusher ring 303 obstructing the cavity of the lower mold 2 when the glass powder is die-cast.
[0039] The pressing mechanism 5 includes a mounting base 501, a lowering cylinder 502, and an upper mold 503. The mounting base 501 is fixedly connected to the top surface of the mounting box 1 on the side near the lower mold 2. The lowering cylinder 502 is fixedly installed on the top surface of the mounting base 501. The telescopic end of the lowering cylinder 502 passes through the mounting base 501 and extends downward. The upper mold 503 is fixedly installed at the telescopic end of the lowering cylinder 502, and the upper mold 503 is perpendicular to the lower mold 2.
[0040] In the above, by setting the upper mold 503 to be vertically aligned with the lower mold 2, the upper mold 503 can be made to close with the lower mold 2 when it moves downward.
[0041] Working principle: When in use, open the flip cover 607 to expose the packing box 601, then pour the prepared ceramic powder into the packing box 601 to fill it. After filling most of it, close the flip cover 607, then start the stepper motor 606 to drive the lead screw 605 to rotate in the forward direction. When the lead screw 605 rotates in the forward direction, it drives the moving plate 603 to move towards the lower material plate 7. When the moving plate 603 moves, it drives the packing box 601 to move synchronously through the fixed connecting rod 602, so that the packing box 601 moves closer to the lower material plate 7. As the packing box 601 gradually approaches the feeding plate 7, it will gradually cover the lower mold 2. The ceramic powder inside the packing box 601 will naturally fall into the cavity of the lower mold 2. At the same time, after the packing box 601 passes the infrared sensor 9, the infrared sensor 9 will sense the passage of the packing box 601 and start the drive motor 41402. The drive motor 41402 will drive the drive gear 41401 to rotate. The rotating drive gear 41401 will drive the outer gear disk 401 to rotate. When the outer gear disk 401 rotates, it will drive the sliding block 408 to move synchronously. The sliding block 408 will drive the mounting plate 403 to move synchronously through the fixed setting block 409. Prior to this, the sliding block 408 is pushed by the push spring 410 to move closer to the lower mold 2. When the sliding block 408 moves closer, it will drive the mounting plate 403 to move closer at the same time through the fixed setting block 409. When the mounting plate 403 moves closer, it will drive the rotating contact wheel 404 to contact the outer surface of the lower mold 2, thereby limiting the distance between the striking block 406 and the lower mold 2 within a certain range. This reduces the problem of the striking block 406 being too close or too far from the lower mold 2 facing the square outer surface when it rotates around the outer gear plate 401, resulting in failure to strike or jamming. At the same time, the striking force of the striking block 406 on the lower mold 2 is kept relatively consistent by limiting the distance. When the outer gear disk 401 rotates, the sliding block 408 will drive the setting sleeve 405 and the rotating gear 411 to move along the outer gear disk 401 simultaneously through the rotating column 407. When the rotating gear 411 moves, it will rotate due to meshing with the inner gear belt 41306. When the rotating gear 411 rotates, it will drive the setting sleeve 405, which is fixed to the rotating column 407, to rotate as well through the fixed rotating column 407. At this time, the setting sleeve 405 will drive the striking block 406 to rotate along the setting sleeve 405 through the threaded spring. With the rotation of the outer gear disk 401, the striking block 406 in the rotating state moves around the outer surface of the lower mold 2, thereby striking the outer surface of the lower mold 2 in all directions, making the striking effect more uniform, and thus making the density of ceramic powder filled inside the lower mold 2 higher. As the rotating gear 411 moves around the outer gear disk 401, it gradually passes the position where the fixed block 41305 and the inner gear belt 41306 are fixed. At this time, the fixed block 41305 will move under the influence of the inner gear belt 41306 and the rotating gear 411. At the same time, under the pushing influence of the spiral spring on the outside of the limit rod 41304, the inner gear belt 41306 and the rotating gear 411 are tightly attached, thereby ensuring that the rotating gear 411 is engaged with the inner gear belt 41306 at any position when it moves around the lower mold 2, so that the rotating gear 411 keeps rotating. Next, as the packing box 601 passes the infrared sensor 9, it continues to move forward and moves back and forth for a period of time near the edge of the mounting box 1. This ensures that the glass powder inside the packing box 601 moves more frequently, making it easier to enter the cavity of the lower mold 2 and make the filling more compact. After a period of time, the stepper motor 606 drives the lead screw 605 to rotate in the opposite direction, causing the packing box 601 to reset and move out of the sensing range of the infrared sensor 9. This causes the drive motor 41402 to stop driving, preventing the lower mold 2 from continuing to vibrate during die casting, which could lead to instability of the die-cast ceramic valve seat ring. At the same time, when the packing box 601 resets, it will smooth out the glass powder on the upper surface of the lower mold 2. When the packing box 601 is fully reset, the lowering cylinder 502 will start and push the upper mold 503 downward, so that it closes with the lower mold 2 to squeeze the glass powder, thereby forming the ceramic valve seat ring. After the upper mold 503 squeezes the ceramic valve seat ring into shape, the upper mold 503 will reset. Then, the pushing cylinder 301 will drive the pushing plate 302 upward, and with the cooperation of the connecting rod 304, it will drive the pushing ring 303 upward at the same time, so that the pushing ring 303 pushes the formed ceramic valve seat ring out of the lower mold 2 and is level with the mounting box 1. When the packing box 601 passes the lower mold 2 again, it will push the ceramic valve seat ring to the lower plate 7 and let the ceramic valve seat ring slide along the lower plate 7. At this time, a container is set under the lower plate 7 for storage, waiting for further processing of the formed ceramic valve seat ring. Then, the pushing ring 303 will reset, freeing up the cavity space of the lower mold 2, so that the glass powder falls into the lower mold 2 again for dense filling.
[0042] Example 2: The difference between this embodiment and embodiment one is that when the mounting plate 403 drives the contact wheel 404 to move along the lower mold 2, the contact wheel 404 will roll along the lower mold 2, which reduces the friction between the contact wheel 404 and the lower mold 2, making the mounting plate 403 more stable when moving along the lower mold 2.
[0043] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
