Description

Technical Field

[0001] This utility model relates to the field of injection molding, and more specifically, to an injection molding device for a fine ceramic potter's wheel. Background Technology

[0002] Linglong porcelain is a gem of traditional Chinese ceramic art. Its characteristic is that various transparent holes (called "Linglong eyes") are carved into the body of the porcelain body in the shape of rice grains, flowers and other shapes. Then, a special Linglong glaze is filled in, and after firing, it presents an artistic effect of being translucent but not leaking water.

[0003] The existing technology still has the following drawbacks: the traditional Linglong ceramic casting process mainly relies on manual glazing, which depends entirely on the individual skills of craftsmen. It is difficult to keep the amount of glaze filling consistent, resulting in significant differences in product quality and extremely low output, which cannot meet the actual needs of large-scale production.

[0004] Therefore, a casting and forming device for a delicate ceramic potter's wheel is proposed. Utility Model Content

[0005] The purpose of this utility model is to address the problems of the current traditional Linglong ceramic casting process, which mainly relies on manual glazing and depends entirely on the individual skills of craftsmen. The amount of glaze filling is difficult to keep consistent, resulting in significant differences in product quality and extremely low output, which cannot meet the actual needs of large-scale production. This utility model provides a casting device for a Linglong ceramic wheel to solve the above problems.

[0009] The leveling assembly includes a bracket bolted to the top of the blank holder. A third motor is bolted to the top of the bracket. A screw is installed at the output end of the third motor, and a second electric push rod is slidably connected to the screw via a slider. A first spring is fixedly connected to the other end of the second electric push rod, and a first damper is fixedly connected to the other end of the first spring. A silicone scraper is bolted to the side of the first damper facing the ceramic blank, and the other side of the silicone scraper is tightly fitted to the outer wall of the ceramic blank.

[0010] As a preferred technical solution of this utility model, a telescopic cylinder is rotatably installed on the top of the bracket, and a telescopic rod is installed at the other end of the telescopic cylinder. A positioning block is bolted to the end of the telescopic rod away from the bracket.

[0024] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby providing a clearer and more definite definition of the scope of protection of the present invention.

[0025] Example: Figures 1-5 As shown, this embodiment proposes a casting forming device for a fine ceramic throwing machine, including: a blank holder 1 and a ceramic blank 2. A casting component 3 for casting material into the fine holes on the ceramic blank 2 is fixedly installed on the top of the blank holder 1. A leveling component 4 for assisting the casting component 3 in leveling is fixedly installed on the top of the blank holder 1. The casting component 3 and the leveling component 4 are arranged at intervals on the top of the blank holder 1.

[0026] The filling assembly 3 includes a filling rack 301 bolted to the top of the blank 1. A first motor 302 is bolted to the top of the filling rack 301. A lead screw 303 is installed at the output end of the first motor 302. A first electric push rod 304 is slidably installed on the lead screw 303 via a slider. An annular plate 305 is bolted to the other end of the first electric push rod 304. A filling box 306 is connected to the annular plate 305 via a support rod. A discharge nozzle 307 is provided through the end of the filling box 306 facing the ceramic blank 2. A second motor 308 is bolted to the other end of the filling box 306. A conveying auger 309 is installed at the output end of the second motor 308 and is located inside the filling box 306. When performing the filling of the crystalline eye, the first motor 302 is started first. The first motor 302 drives the lead screw 303 to rotate. The rotation of the lead screw 303 causes the slider to drive the first electric push rod 304 to rise and fall on the lead screw 303, thereby adjusting the height of the annular plate 305 and the filling box 306 so that they are aligned with the ceramic blank 2. Then, the first electric push rod 304 is started. The first electric push rod 304 can further fine-tune the horizontal position of the filling box 306 so that the discharge nozzle 307 is precisely aligned with the crystalline eye on the ceramic blank 2. The second motor 308 is started. The second motor 308 drives the conveying auger 309 to rotate, and the material in the filling box 306 is evenly conveyed into the crystalline eye through the discharge nozzle 307.

[0027] The leveling assembly 4 includes a bracket 401 bolted to the top of the blank 1. A third motor 402 is bolted to the top of the bracket 401. A screw 403 is installed at the output end of the third motor 402. A second electric push rod 404 is slidably connected to the screw 403 via a slider. A first spring 405 is fixedly connected to the other end of the second electric push rod 404. A first damper 406 is fixedly connected to the other end of the first spring 405. A silicone scraper 407 is bolted to the side of the first damper 406 facing the ceramic blank 2. The other side of the silicone scraper 407 is tightly fitted to the outer wall of the ceramic blank 2. During the leveling operation, the third motor 402 is first started to drive the screw 403 to rotate. The rotation of the screw 403 drives the slider, which in turn causes the second electric push rod 404 to rise and fall on the screw 403, thereby adjusting the height of the silicone scraper 407. The second electric push rod 404 is then started to finely adjust the horizontal position of the silicone scraper 407, ensuring that the silicone scraper 407 is in close contact with the outer wall of the ceramic blank 2. When the silicone scraper 407 contacts the outer wall of the ceramic blank 2 and begins the leveling operation, the buffer mechanism composed of the first spring 405 and the first damper 406 is activated, effectively absorbing the impact force generated by minor unevenness or vibration between the scraper and the blank. This ensures that the silicone scraper 407 always adheres to the surface of the blank with a constant and gentle pressure, avoiding damage to the not-fully-dried and relatively soft ceramic blank 2 caused by the rigid scraper.

[0028] like Figure 2 , Figure 3 andFigure 5 As shown, a telescopic cylinder 5 is rotatably mounted on the top of the bracket 401, and a telescopic rod 6 is fitted to the other end of the telescopic cylinder 5. A positioning block 7 is bolted to the end of the telescopic rod 6 away from the bracket 401. When the telescopic cylinder 5 is activated, the internal piston moves to drive the telescopic rod 6 to extend and retract. The extension and retraction of the telescopic rod 6 causes the positioning block 7 at its end to precisely enter the internal cavity of the ceramic blank 2, performing preliminary positioning of the ceramic blank 2. The extension and retraction length of the telescopic rod 6 can be controlled to adapt to ceramic blanks 2 of different depths.

[0029] like Figures 1-3 and Figure 5 As shown, a second damper 8 is provided on the positioning block 7, and two sets of the second dampers 8 are symmetrically arranged. The other end of the second damper 8 is bolted with a second spring 9. When the positioning block 7 enters the internal cavity of the ceramic blank 2 for positioning, the support block 10, under the thrust of the second spring 9 and guided by the second damper 8, unfolds outward until it is tightly attached to the inner wall of the ceramic blank 2, thereby achieving internal support and fixation of the ceramic blank 2 and effectively preventing the thin-walled ceramic blank 2 from collapsing, cracking or deforming during the stress process.

[0030] like Figures 1-3 and Figure 5 As shown, the other end of the second spring 9 is bolted to a support block 10, and the outer contour of the support block 10 is adapted to the inner contour of the ceramic blank 2. The design of the support block 10 allows it to adapt to the inner wall contour of the blank within a certain size range, ensuring a firm fixation without damaging the blank due to excessive compression, thus enhancing its versatility.

[0031] like Figure 1 , Figure 3 and Figure 4 As shown, a servo motor 11 is bolted to the bottom of the blank holder 1, and a turntable 12 is bolted to the output end of the servo motor 11. The turntable 12 is located on top of the blank holder 1, and the ceramic blank 2 is located on top of the turntable 12. The servo motor 11 drives the turntable 12 to rotate, thereby causing the ceramic blank 2 placed on the turntable 12 to rotate. The rotation of the ceramic blank 2, in conjunction with the fixed injection box 306 and scraper, can easily complete the injection of all the fine holes in the circumferential direction without the need to frequently move the injection equipment.

[0032] like Figure 4 and Figure 5 As shown, the lead screw 303 is located in the limiting groove inside the material injection frame 301, and the material injection box 306 has a feed inlet 13 running through it. The movement of the lead screw 303 within the limiting groove ensures the straightness and stability of the slider movement. The feed inlet 13 is used to continuously replenish the mud into the material injection box 306, achieving uninterrupted material supply, meeting the needs of batch continuous production, and avoiding frequent machine shutdowns for material replenishment.

[0033] Working Principle: This utility model provides a casting and forming device for a delicate ceramic potter's wheel. The specific steps are as follows: Step 1: Place the ceramic blank 2 with the delicate eye carving completed on the center of the turntable 12. The telescopic cylinder 5 is activated, and its internal piston movement drives the telescopic rod 6 to extend and retract. The extension and retraction of the telescopic rod 6 drives the positioning block 7 at the end to accurately enter the internal cavity of the ceramic blank 2, performing preliminary positioning of the ceramic blank 2. When the positioning block 7 enters the internal cavity of the ceramic blank 2 for positioning, the support block 10, under the pushing force of the second spring 9, is pushed by the second damper 8. Guided by the direction, it unfolds outward until it fits tightly against the inner wall of the ceramic blank 2, thereby achieving internal support and fixation for the ceramic blank 2; Step 2: Start the first motor 302, which drives the lead screw 303 to rotate. The rotation of the lead screw 303 will cause the slider to drive the first electric push rod 304 to rise and fall on the lead screw 303, thereby adjusting the height of the annular plate 305 and the injection box 306 to align them with the ceramic blank 2. Then, start the first electric push rod 304, which can further fine-tune the horizontal position of the injection box 306, allowing the nozzle 3 to... 07. Precisely align the material with the opening on the ceramic blank 2, and start the second motor 308. The second motor 308 drives the conveying auger 309 to rotate, and evenly conveys the material in the filling box 306 into the opening through the discharge nozzle 307; Step 3: Start the third motor 402 to drive the screw 403 to rotate. The rotation of the screw 403 drives the slider, which in turn causes the second electric push rod 404 to rise and fall on the screw 403, thereby adjusting the height of the silicone scraper 407. Start the second electric push rod 404 to finely adjust the horizontal position of the silicone scraper 407, ensuring... The silicone scraper 407 is in close contact with the outer wall of the ceramic blank 2. When the silicone scraper 407 contacts the outer wall of the ceramic blank 2 and begins to scrape, the buffer mechanism composed of the first spring 405 and the first damper 406 is activated to effectively absorb the impact force caused by minor unevenness or vibration between the scraper and the blank. The turntable 12 is driven to rotate by the servo motor 11, thereby driving the ceramic blank 2 placed on the turntable 12 to rotate. The rotation of the ceramic blank 2, together with the fixed injection box 306 and the scraper, can easily complete the injection of all the fine holes in the circumferential direction.

[0034] All technical features in this embodiment can be freely combined according to actual needs.

[0035] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
