Description

Technical Field

[0001] This utility model relates to the technical field of dental prosthesis production, and more specifically, it relates to a mold-pouring device for prosthesis production. Background Technology

[0002] In the denture manufacturing process, the mold-filling device is a key piece of equipment for achieving precise molding of denture blanks. Its performance directly affects the dimensional accuracy and production efficiency of dentures. Existing mold-filling devices usually consist of a filling tank, a mixing structure, and a mold fixing component. During operation, denture materials need to be injected into the filling tank, mixed evenly, and then injected into the mold. After the material solidifies, the mold is removed to complete the molding process.

[0003] Existing dental prosthesis molding equipment has been found to have the following issues during use: 1. Existing mixing components are mostly fixed to the filling tank by welding or multiple sets of bolts. When it is necessary to clean the mixing blades or replace damaged parts, a large number of fasteners need to be disassembled or professional tools are required, which is cumbersome and time-consuming.

[0004] 2. Existing molds are mostly directly clamped or bolted into the sleeve. After the material is cured, the mold and the inner wall of the sleeve are easily tightly adhered due to the adsorption force. When removing them, manual prying or the use of auxiliary tools is required. This not only increases the labor intensity of workers, but may also cause mold deformation or damage to the denture blank due to uneven force, affecting the continuity of production and the qualification rate of finished products. Therefore, it has poor practicality. Utility Model Content

[0005] (a) Technical problems to be solved In view of the problems existing in the prior art, this utility model provides a mold filling device for denture production, so as to solve the technical problems mentioned in the background art, such as the difficulty in disassembling the stirring structure in the filling barrel and the cumbersome process of removing the filling mold.

[0006] (II) Technical Solution To achieve the above objectives, this utility model provides the following technical solution: a mold-filling device for denture production, comprising a base, an mounting plate at the rear end of the top of the base, a mounting seat at the top front end of the mounting plate, a filling barrel inside the mounting seat, a threaded end at the top outer side of the filling barrel, a mounting ring threadedly connected to the top outer side of the filling barrel via the threaded end, a cover plate at the top inner side of the mounting ring, the bottom of the cover plate connected to the top of the filling barrel, a feed pipe at the front end of the top of the cover plate, a stirring assembly at the bottom of the cover plate, a fixing plate at the bottom front end of the mounting plate, a pre-drilled hole in the fixing plate, a sleeve inside the pre-drilled hole, a mold fitted inside the sleeve, an annular plate at the top outer side of the mold, the bottom of the annular plate being in close contact with the top of the sleeve, and an extrusion mechanism at the bottom inner side of the sleeve.

[0007] The present invention is further configured such that the extrusion mechanism includes an extrusion plate, and sliding components are provided at both the left and right ends of the inner side of the sleeve. An installation block is slidably connected to the inner side of the sleeve through the sliding components. A pre-drilled hole is provided at the top of the installation block, and a connecting rod is provided in the pre-drilled hole of the installation block. An extrusion plate is provided at the top of the connecting rod, and the extrusion plate is located below the mold. A connecting block is provided at the bottom of the outer side of the connecting rod, and a sliding rod is provided at the front end of the connecting block. A spring-loaded component is provided at the top of the sliding rod, and a fixing block is provided at the top of the sliding rod through the spring-loaded component. The rear end of the fixing block is connected to the front end of the fixing plate. The mold is pushed from the bottom by the extrusion plate, so that the mold is separated from the inner wall of the sleeve, which solves the problem that the traditional mold is difficult to remove due to the suction force. The sliding components provide guidance for the movement of the installation block and the extrusion plate, ensuring that the extrusion plate is subjected to balanced force.

[0008] The present invention is further configured such that the rebound assembly includes a connecting spring, a support block is provided at the bottom of the fixing block, a groove is provided at the bottom of the support block, a connecting spring is provided at the top of the groove of the support block, and the bottom of the connecting spring is connected to the top of the slide rod, the outer top of the slide rod is slidably connected to the groove of the support block, and a damping rod is provided on the inner side of the connecting spring; the elastic force of the connecting spring provides power for the reset of the slide rod and the extrusion plate, eliminating the need for manual operation and improving the reset efficiency after demolding; the damping rod effectively buffers the impact force when the spring resets, avoiding component wear caused by hard collision between the slide rod and the support block.

[0009] This invention is further configured such that the stirring assembly includes a drive motor, the drive motor is mounted on the top of the cover plate, and a stirring rod is mounted at the bottom output end of the drive motor. Multiple sets of stirring blades are evenly arranged on the outer side of the stirring rod. Scrapers are slidably attached to both ends of the inner side of the filling tank, and the other ends of both sets of scrapers are connected to one end of the corresponding stirring blade. The even distribution of the stirring blades ensures thorough mixing of the denture material, avoiding differences in denture blank performance due to uneven mixing and guaranteeing molding quality. The synchronous movement of the scrapers and stirring blades allows for real-time cleaning of residual material on the inner wall of the filling tank, solving the problem of traditional stirring structures failing to clean tank wall residue, leading to material waste or affecting subsequent mixing.

[0010] The present invention is further configured such that the sliding component includes a guide block, and the inner left and right ends of the sleeve are provided with sliding grooves, and guide blocks are slidably arranged in both sets of sleeve sliding grooves, and the two ends of the mounting block are respectively connected to one end of a set of guide blocks; the sliding cooperation between the guide block and the sliding groove provides precise guidance for the mounting block, avoids the extrusion plate from tilting due to uneven force when pushing the mold, and ensures that the mold is subjected to balanced force.

[0011] The present invention is further provided with a handle at the front end of the support block and a pressing block at the bottom of the slide bar; this provides a convenient force application point for fixing the support block during operation, avoids the support block shaking during demolding and affecting the stability of the extrusion plate, and improves the safety of operation.

[0012] The present invention is further configured such that an annular sealing ring is provided at the top of the filling barrel, and the bottom of the cover plate and the top of the annular sealing ring are in close contact; this enhances the sealing performance between the cover plate and the filling barrel, ensuring an effective seal can be formed under various working conditions.

[0013] (III) Beneficial Effects Compared with the prior art, this utility model provides a mold-pouring device for denture production, which has the following beneficial effects: 1. The installation ring and threaded connection at the threaded end enable quick assembly and disassembly of the cover plate and mixing components to the filling tank, solving the problem of cumbersome disassembly caused by the fixed connection of the traditional mixing structure. This facilitates regular cleaning of the mixing components and the inner wall of the filling tank to remove residual sticky materials, ensuring the uniformity of subsequent mixing.

[0014] 2. The die is pushed from the bottom by the extrusion plate, which separates the die from the inner wall of the sleeve. This solves the problem that traditional dies are difficult to remove due to adsorption force. The sliding component provides guidance for the movement of the mounting block and the extrusion plate, ensuring that the extrusion plate is subjected to balanced force. Attached Figure Description

[0020] Please see Figure 1-5 A mold-filling device for denture production includes a base 1, a mounting plate 2 at the rear end of the top of the base 1, a mounting seat 3 at the top front end of the mounting plate 2, a filling tank 4 inside the mounting seat 3, a threaded end at the top outer side of the filling tank 4, a mounting ring 5 threadedly connected to the top outer side of the filling tank 4 via the threaded end, a cover plate 6 at the top inner side of the mounting ring 5, the bottom of the cover plate 6 connected to the top of the filling tank 4, a feed pipe 7 at the front end of the top of the cover plate 6, a stirring assembly at the bottom of the cover plate 6, a fixing plate 8 at the bottom front end of the mounting plate 2, a pre-drilled hole in the fixing plate 8, a sleeve 9 inside the pre-drilled hole, a mold 10 fitted inside the sleeve 9, an annular plate 11 at the top outer side of the mold 10, the bottom of the annular plate 11 tightly attached to the top of the sleeve 9, and an extrusion mechanism at the bottom inner side of the sleeve 9.

[0021] In this embodiment, during use, the denture material is injected into the filling tank 4 through the feed pipe 7. The filling tank 4 is fixed to the top front end of the mounting plate 2 by the mounting base 3. The stirring assembly is started to stir the material in the filling tank 4. The stirred material is injected into the mold 10 inside the sleeve 9. The mold 10 is positioned by the annular plate 11 tightly adhering to the top of the sleeve 9. After the mold is filled, the mold 10 is removed from the sleeve 9 by the extrusion mechanism at the bottom inner side of the sleeve 9. When it is necessary to clean or maintain the stirring assembly, the mounting ring 5 is rotated to make it screw out along the threaded end of the filling tank 4. The mounting ring 5 drives the cover plate 6 and the bottom stirring assembly to detach from the filling tank 4, and the operation can then be performed.

[0022] More specifically, the drive motor 22 on the top of the cover plate 6 is started, and the drive motor 22 drives the stirring rod 23 at the bottom to rotate. The multiple sets of stirring blades 24 on the outside of the stirring rod 23 rotate together to stir the denture material in the filling tank 4. At the same time, the stirring blades 24 drive the scrapers 25 at both ends to slide along the inner side of the filling tank 4 to scrape off the material remaining on the tank wall.

[0023] Please see Figure 1 and Figure 4 As one embodiment of the extrusion mechanism: the extrusion mechanism includes an extrusion plate 12, and sliding components are provided at both ends of the inner side of the sleeve 9. An installation block 13 is slidably connected to the inner side of the sleeve 9 through the sliding components. A reserved hole is provided at the top of the installation block 13, and a connecting rod 14 is provided in the reserved hole of the installation block 13. The extrusion plate 12 is provided at the top of the connecting rod 14, and the extrusion plate 12 is located below the mold 10. A connecting block 16 is provided at the bottom of the outer side of the connecting rod 14. A sliding rod 17 is provided at the front end of the connecting block 16. A spring-loaded component is provided at the top of the sliding rod 17. A fixing block 18 is provided at the top of the sliding rod 17 through the spring-loaded component. The rear end of the fixing block 18 is connected to the front end of the fixing plate 8.

[0024] Specifically, when removing the mold 10, the operating slide bar 17 moves upward. The slide bar 17 drives the connecting rod 14 and the mounting block 13 to rise along the sliding assembly through the connecting block 16. The extrusion plate 12 on the top of the mounting block 13 moves upward accordingly, pushing the mold 10 out of the sleeve 9 from the bottom of the mold 10. At this time, the springback assembly on the top of the slide bar 17 is compressed. After releasing the slide bar 17, the springback assembly drives the slide bar 17, the connecting block 16, the connecting rod 14 and the extrusion plate 12 to reset. The extrusion plate 12 returns to the initial position below the mold 10. The fixing block 18 provides support for the springback assembly to ensure the stability of the entire mechanism.

[0025] Please refer to Figures 2-4As a further embodiment of the extrusion mechanism: the springback assembly includes a connecting spring 19, a support block 20 is provided at the bottom of the fixing block 18, a groove is provided at the bottom of the support block 20, the connecting spring 19 is provided at the top of the groove of the support block 20, and the bottom of the connecting spring 19 is connected to the top of the slide rod 17, the outer top of the slide rod 17 is slidably connected to the groove of the support block 20, and a damping rod 21 is provided on the inner side of the connecting spring 19.

[0026] Specifically, when the slide bar 17 moves upward, its top compresses the connecting spring 19 in the groove of the support block 20, while the damping rod 21 contracts along with the spring. When the slide bar 17 is released, the elastic force of the connecting spring 19 pushes the slide bar 17 downward to reset. The damping rod 21 provides buffering during the spring's extension and retraction, preventing impact when the slide bar 17 resets quickly. The support block 20 provides installation space for the connecting spring 19 and the damping rod 21, ensuring a stable and controllable rebound process. In summary, the overall equipment is in use (or running): During feeding, the denture material is injected into the filling tank 4 through the feeding pipe 7. The annular sealing ring 15 at the bottom of the cover plate 6 is tightly attached to the top of the filling tank 4 to prevent leakage. The drive motor 22 is started, and the stirring rod 23 drives the stirring blade 24 to stir the material. The scraper 25 scrapes off the residue on the inner wall of the filling tank 4 along with the blade. After mixing, the material is injected into the mold 10 inside the sleeve 9. After the mold is filled, hold the handle 27 to fix the support block 20, and then press the pressing block 28 at the bottom of the slide rod 17. The slide rod 17 drives the connecting block 16, the connecting rod 14 and the mounting block 13 to rise. The guide block 26 slides along the slide groove of the sleeve 9. The extrusion plate 12 pushes the mold 10 out of the sleeve 9. Then the staff can take out the mold 10. Finally, release the pressing block 28, and the connecting spring 19 and the damping rod 21 drive the slide rod 17 and the extrusion plate 12 to reset. When disassembling the mixing assembly, rotate the mounting ring 5 along the threaded end of the filling bucket 4 to unscrew the cover plate 6, drive motor 22, mixing rod 23 and scraper 25, and then clean them.

[0027] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model 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 this utility model. The scope of this utility model is defined by the appended claims and their equivalents.
