[0012] This invention provides a porcelain-fused-to-metal (PFM) device for denture production. Compared with the prior art, it has the following advantages:

[0013] 1. The porcelain-fused-to-metal (PFM) device for denture production, by incorporating a storage component within the device, allows the hydraulic cylinder assembly, buffer block, drive component, two sets of rotating frames, storage cylinder, storage frame, filter block, cylinder assembly, guide frame, and drive rod to work together to store and adjust the dentures according to the user's needs. Furthermore, a vacuum pump, along with curved pipes, conduits, three-way valves, and two sets of connecting pipes, performs pre-vacuuming on the dentures located in the main body of the PFM furnace. This provides protection for the dentures after porcelain fusing. This setup, through sealing and vacuuming the porcelain-fused-to-metal end before fusing, reduces the impact of air on the porcelain-fused-to-metal process. After porcelain fusing, storing the dentures prevents direct contact between the dentures and outside air, thus avoiding any impact on the quality of the finished product.

[0014] 2. The porcelain-fused-to-metal device for denture production has a drive unit inside the device, which allows the motor to work with gears and gear rings. By adjusting the angle of the rotating frame, the positions of the two sets of storage cylinders and storage frames can be switched, which helps the device to replace dentures and improves the efficiency of porcelain-fused-to-metal production.

[0025] A cylinder assembly 245 is installed on the inner side of the lifting seat 26 near the protective frame 25. A guide frame 246 is installed on the top extended end of the cylinder assembly 245. Two sets of drive rods 247 are connected to the upper side of the guide frame 246 and are respectively fixedly connected to the bottom of the two sets of storage frames 243. A vacuuming component 248 for vacuuming the baking end is installed on the upper side of the lifting seat 26. A drive component 23 for driving the rotating frame 241 to rotate is installed on the lifting seat 26. The cylinder end of the hydraulic cylinder assembly 21 is fixedly connected to the control console 1. A first stop block is installed on the bottom extended end of the hydraulic cylinder assembly 21 and is slidably connected to the inside of the buffer block 22. A first buffer groove is provided in the buffer block 22 and is slidably connected to the first stop block. A set of slots for denture insertion is provided on both sides of the storage frame 243.

[0026] The drive rod 247 is slidably connected to the bottom of the storage cylinder 242; the extended end of the cylinder assembly 245 is fixedly connected to the second stop; the lower side of the rotating frame 241 has a second buffer groove that is slidably connected to the second stop; the rotating frame 241 is an annular frame; the bottom of the drive rod 247 is fixedly connected to an anti-detachment block; the upper side of the rotating frame 241 has an annular groove that is slidably connected to the anti-detachment block; the bottom of the storage cylinder 242 is fixedly connected to a corrugated tube that is fixedly connected to the anti-detachment block near the outer side of the drive rod 247; the top of the protective frame 25 is fitted to the bottom of the rotating frame 241; the vacuuming component 248 includes a fixed connection. On the left side of the lifting seat 26, there is a vacuum pump 2481. The right side of the vacuum pump 2481 is fixedly connected to the suction end of the vacuum pump 2481 and the bent pipe 2482 is fixedly connected to the protective frame 25 and the lifting seat 26.

[0028] The main difference between the second implementation method and the first implementation method is that:

[0029] The drive unit 23 includes a motor 231 fixedly connected to the lifting seat 26. The motor 231 is located inside the protective frame 25 and the output end is coaxially fixedly connected to a gear 232. The bottom rotating end of the rotating frame 241 is coaxially fixedly connected to a gear ring 233 of the core of the gear 232. The motor 231 is a servo motor. The motor 231 cooperates with the gear 232 and the gear ring 233. By adjusting the angle of the rotating frame 241, the positions of the two sets of storage tubes 242 and storage frames 243 can be switched, which helps the device to replace dentures.

[0030] Furthermore, all content not described in detail in this specification is existing technology known to those skilled in the art, and the model parameters of each electrical appliance are not specifically limited; conventional equipment can be used.

[0031] In use, the user moves the denture to be heated to the end of the storage frame 243, which is closer to the end furthest from the main body of the porcelain furnace. The denture is then placed inside the storage frame 243 through the slot on its side. The user then activates the cylinder assembly 245, which pulls the two sets of drive rods 247, the storage frame 243, and the filter block 244 downwards via the guide frame 246. The storage frame 243 gradually sinks into the storage cylinder 242. The user then activates the motor 231, which drives the rotating frame 241 and the two sets of storage cylinders 247 downwards via the gear 232 and gear ring 233. The cylinder 242, storage frame 243, drive rod 247, and array filter block 244 rotate, causing the storage cylinder 242 containing the dentures to be moved to the lower side of the ceramic furnace body 3. The anti-detachment block at the bottom of the drive rod 247 slides along the anti-detachment groove in the guide frame 246, allowing the hydraulic cylinder assembly 21 to drive the lifting seat 26, drive component 23, adjustment component 24, and protective frame 25 to move upward through the buffer block 22, so that the storage cylinder 242 fully enters the heating groove inside the ceramic furnace body 3. At this time, the upper end of the rotating frame 241 is tightly pressed against the bottom of the ceramic furnace body 3.

[0032] The cylinder assembly 245, in conjunction with the guide frame 246 and the drive rod 247, adjusts the height of the storage frame 243 and the denture, connecting the interior of the storage frame 243 to the heating groove inside the porcelain furnace body 3. The vacuum pump 2481 is then activated. The vacuum pump 2481, through the bent pipe 2482, the guide pipe 2483, the three-way valve 2484, the connecting pipe 2485, the air vent at the bottom of the storage cylinder 242, and the filter block 244, performs vacuuming on the connection between the storage frame 243 and the heating groove of the porcelain furnace body 3. After the vacuuming operation is complete, the three-way valve 2484 is reversed, allowing the porcelain furnace body 3 to heat and porcelain-melt the denture inside the storage frame 243. Meanwhile, another set of dentures, exposed to the outside and far from the porcelain furnace body, is used for porcelain-melting. Add the required porcelain dentures to the storage frame 243 of body 3. Since the porcelain furnace body 3 is existing technology, its internal structure and porcelain firing principle will not be described in detail. After the porcelain firing is completed, let the storage frame 243 move the porcelain-fired dentures back to their original positions. Then, separate the storage cylinder 242 and the rotating frame 241 from the porcelain furnace body 3, and let the storage cylinder 242 containing the porcelain-fired dentures rotate to its original loading position. Allow the original porcelain-fired storage cylinder 242 and storage frame 243 to cool naturally. Then, open the storage frame 243 and take out the porcelain-fired dentures. Since the position adjustment steps of the storage frame 243 have been described before, they will not be described in detail again. Repeat the above porcelain firing steps to process the subsequently added dentures.
