Description

Technical Field

[0001] The utility model belongs to the technical field of zirconia ceramic forming and processing, in particular to a zirconia ceramic tape casting forming and processing device. Background Art

[0002] Zirconia ceramics are ceramics with stable cubic zirconium oxide as the main crystal phase. Zirconia toughened ceramics, developed in the 1970s using zirconium oxide phase transformation, have excellent mechanical (highest fracture toughness) and thermal properties. They are a promising new type of structural ceramic material and have been widely used in many fields.

[0003] The molding of zirconia ceramics includes dry pressing, isostatic pressing, slip casting, hot die casting, tape casting, injection molding, plastic extrusion molding, colloidal solidification molding, etc. Among them, tape casting is a commonly used method for producing thin-sheet zirconia ceramic products. However, in the existing zirconia ceramic tape casting process, the material is first accumulated on the mold surface, and then the material is evenly dropped into the mold cavity through a scraper. This method will result in more material accumulation in the initial stage, and the scraper is prone to overflow to both sides during the scraping process. In the later stage, when there is less remaining material, some mold cavities may not get enough material, affecting the consistency of the final product quality. For this reason, we propose a zirconia ceramic tape casting processing device. Utility Model Content

[0004] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a zirconia ceramic tape casting molding processing device which can overcome the above problems or at least partially solve the above problems.

[0005] In order to solve the above technical problems, the basic concept of the technical solution adopted by the utility model is: a zirconia ceramic casting molding processing device, including a workbench, and also including: a pair of slide rails and a pair of support plates are symmetrically arranged on the workbench, the slide rails are slidably connected to the mold, and the support plates are symmetrically provided with slide grooves and guide rails; a lower material bin that can move in the horizontal direction, the bottom of the lower material bin is provided with a discharge port and a scraper, the scraper is rotatably connected to the lower material bin, and a limit plate is fixedly connected to the scraper, and sliders and rollers are respectively arranged on both sides of the lower material bin, and the sliders and rollers correspond to the slide grooves and guide rails respectively; when the lower material bin moves in the horizontal direction, the zirconia ceramic material falls onto the mold from the discharge port, and the scraper scrapes off the zirconia ceramic material on the surface of the mold; when the lower material bin moves in the opposite direction in the horizontal direction, the scraper pushes the mold to slide out of the slide rail.

[0006] Preferably, the support plate is fixedly connected to a mounting plate, the mounting plate is fixedly connected to a motor, the output end of the motor passes through the mounting plate and is fixedly connected to a threaded rod, the threaded rod passes through a slide groove and is rotatably connected to the slide groove, a slider is slidably connected in the slide groove, and the slider is threadedly connected to the threaded rod.

[0007] Preferably, a spiral conveying rod is provided in the lower material bin, one end of the spiral conveying rod passes through the lower material bin and is rotatably connected to the lower material bin, and a hopper is also fixedly connected to the lower material bin.

[0008] Preferably, a ratchet is rotatably connected inside the roller, the other side of the ratchet is fixedly connected to the spiral conveying rod, and a pawl is also rotatably connected inside the roller.

[0009] Preferably, a groove is provided in the slide rail, a spring is fixedly connected in the groove, a positioning block is fixedly connected to the other end of the spring, and the positioning block corresponds to the groove.

[0010] Preferably, the workbench is also provided with a material return port, and a corresponding material return slope is fixedly connected to the lower part of the material return port.

[0012] After adopting the above technical scheme, the utility model has the following beneficial effects compared with the prior art: the utility model solves the problem of excessive material accumulation in the initial position during traditional tape casting by designing a lower material bin that can move in the horizontal direction. The rotatable scraper can not only scrape the surface of the mold, but also push the tape casting mold out of the slide rail. A spiral conveying rod driven by a roller is arranged in the lower material bin, which can evenly distribute the zirconia ceramic material in the lower material bin during the movement of the lower material bin, so that the zirconia ceramic material can evenly flow out from the lower material port, preventing too much material in some areas of the mold and too little material in other areas.

The following embodiments are used to illustrate the utility model but are not used to limit the scope of the utility model.

[0023] Example: Refer to Figure 1-Figure 6, a zirconia ceramic tape casting molding processing device, including a workbench 1, also includes: a pair of slide rails 12 and a pair of support plates 2 are symmetrically arranged on the workbench 1, a mold 8 is slidably connected to the slide rails 12, and a slide groove 3 and a guide rail 32 are symmetrically arranged on the support plate 2; a lower bin 5 that can move in the horizontal direction, a lower bin 5 is provided with a lowering port 53 and a scraper 7 at the bottom, the scraper 7 is rotatably connected to the lower bin 5, a limit plate 71 is fixedly connected to the scraper 7, and sliders 42 and rollers 6 are respectively arranged on both sides of the lower bin 5, and the sliders 42 and rollers 6 correspond to the slide groove 3 and the guide rail 32 respectively; when the lower bin 5 moves in the horizontal direction, the zirconia ceramic material falls onto the mold 8 from the lowering port 53, and the scraper 7 scrapes off the zirconia ceramic material on the surface of the mold 8; when the lower bin 5 moves in the opposite direction in the horizontal direction, the scraper 7 pushes the mold 8 to slide out of the slide rail 12; a mounting plate 31 is fixedly connected to the support plate 2, and a mounting plate 31 is fixedly connected There is a motor 4, the output end of the motor 4 passes through the mounting plate 31 and is fixedly connected with a threaded rod 41, the threaded rod 41 passes through the slide 3 and is rotatably connected to the slide 3, a slider 42 is slidably connected in the slide 3, and the slider 42 is threadedly connected to the threaded rod 41; a spiral conveying rod 52 is arranged in the lower bin 5, one end of the spiral conveying rod 52 passes through the lower bin 5 and is rotatably connected to the lower bin 5, and a hopper 51 is also fixedly connected to the lower bin 5; a ratchet 521 is rotatably connected in the roller 6, and the other side of the ratchet 521 is fixedly connected to the spiral conveying rod 52, and a pawl 61 is also rotatably connected in the roller 6; a groove is provided in the slide rail 12, and a spring 122 is fixedly connected in the groove, and the other end of the spring 122 is fixedly connected to a positioning block 121, and the positioning block 121 corresponds to the groove; a material withdrawal port 13 is also provided on the workbench 1, and a corresponding material withdrawal slope 131 is fixedly connected to the lower part of the material withdrawal port 13; a support leg 11 is fixedly connected to the bottom of the workbench 1;

[0024] Align both sides of the mold 8 with the slide rail 12 and push it in. When the mold 8 contacts the inclined surface of the positioning block 121, push the positioning block 121 into the groove and compress the spring 122, and continue to push the mold 8 in. When the mold 8 is disengaged from the positioning block 121, the spring 122 pushes the positioning block 121 to reset. Add the fluid zirconia ceramic material from the hopper 51 into the lower bin 5, start the motor 4, and the motor 4 drives the threaded rod 41 to rotate, further making the slider 42 slide horizontally in the slide groove 3, and the slider 42 drives the lower bin 5 to move. At this time, the roller 6 rotates on the guide rail 32, and the pawl 61 clamps the ratchet 521 in the roller 6, so that the ratchet 521 drives the spiral conveying rod 52 to rotate, so that the zirconia ceramic material in the lower bin 5 is evenly distributed; the scraper 7 is located at In the initial position, its bottom is slightly lower than the upper surface of the mold 8. During the movement of the lower hopper 5, the lower part of the scraper 7 contacts the mold 8 and rotates until one side of the limit plate 71 rests against the bottom of the lower hopper 5. As the lower hopper 5 continues to move, the scraper 7 scrapes off the excess zirconia ceramic material on the surface of the mold 8. The excess zirconia ceramic material will eventually fall into the return port 13 and slide out of the device by the return slope 131. When the scraper 7 is separated from the mold 8, the scraper 7 returns to the initial state. At this time, the motor 4 is driven in the reverse direction to make the lower hopper 5 move in the reverse direction. At this time, the rotation of the roller 6 will no longer drive the spiral conveying rod 52, and the scraper 7 cannot rotate under the action of the limit plate 71 to push the mold 8 out of the slide rail 12.

[0025] The utility model solves the problem of excessive material accumulation at the initial position during traditional tape-casting by designing a lower material bin 5 that can move in the horizontal direction. The rotatable scraper 7 can not only scrape the surface of the mold 8, but also push the tape-casting mold 8 out of the slide rail 12. A spiral conveying rod 52 driven by a roller 6 is arranged in the lower material bin 5, which can evenly distribute the zirconia ceramic material in the lower material bin 5 during the movement of the lower material bin 5, so that the zirconia ceramic material can evenly flow out from the lower material port 53, thereby preventing excessive material in some areas of the mold 8 and less material in other areas.
