[0021] Please see Figures 1-6This utility model provides a technical solution: a scald-proof porcelain denture furnace, comprising a base 1, an oven 2, and an auxiliary mechanism 6.

A servo motor 601 is installed inside the base 1, along with a transparent protective plate 614. The output end of the servo motor 601 is connected to a first threaded post 602. A first synchronous pulley 603 is connected to the top of the outer wall of the first threaded post 602. The first synchronous pulley 603 is connected to a second synchronous pulley 604 via a synchronous belt. A second threaded post 605 is connected inside the second synchronous pulley 604. Guide seats 606 are threadedly connected to both the second threaded post 605 and the middle of the outer wall of the first threaded post 602. One side of the outer wall of the guide seat 606 is connected to the lifting platform 3. A limit seat 607 is welded to the middle of the bottom of the placement platform 4. A drive motor 6 is connected to the middle of the base 1 via a support seat. 09, and the output end of the drive motor 609 is connected to a threaded rod 610, and a fixed seat 611 is threadedly connected to the middle of the outer wall of the threaded rod 610; the bottom of the limiting seat 607 has a "U" shaped structure, the fixed seat 611 has an "I" shaped structure, and the top two sides of the fixed seat 611 have limiting grooves corresponding to the bottom of the limiting seat 607; the middle of the inner wall of the lifting platform 3 has a movable groove, and the limiting seat 607 extends into it; the bottom two sides of the placement platform 4 are slidably connected to slide rails 608, and the bottom of the outer wall of the slide rails 608 is welded to the lifting platform 3; the bottom two sides of the fixed seat 611 are slidably connected to limiting posts 612, and the outer two sides of the limiting posts 612 are connected to the support base. The threaded rod 610 is connected to the support seat via a bearing seat on the side away from the drive motor 609; a protective box 613 is provided on the outside of the guide seat 606, and the bottom end of the outer wall of the protective box 613 is welded to the base 1; the bottom end of the second threaded post 605 is connected to the base 1 via a bearing seat; a transparent protective plate 614 is connected to one side of the bottom of the oven 2; the first threaded post 602 and the second threaded post 605 are parallel to each other; the threaded rod 610 and the limiting post 612 are triangularly distributed; the fixed seat 611 is slidably connected to the base 1; the protective box 613 is symmetrically distributed about the vertical midline of the base 1; and a spring for limiting is connected to the middle of the outer wall of the limiting seat 607.

[0022] In practical implementation, when using this anti-scalding porcelain denture furnace, if the placement platform 4 needs to be moved closer to the oven 2 for sintering the denture, the servo motor 601 is first started to drive the first threaded post 602 to rotate. Since the top of the first threaded post 602 is connected to the first synchronous pulley 603, the rotation of the first threaded post 602 will drive the first synchronous pulley 603 to rotate as well. Furthermore, since the first synchronous pulley 603 is connected to the second synchronous pulley 604 via a synchronous belt, the rotation of the first synchronous pulley 603 will drive the second synchronous pulley 604 to rotate as well. Then, the rotation of the second synchronous pulley 604 will drive the second threaded post 605 to rotate as well. And because the first threaded post 602 and the second… Both the threaded column 605 and the guide seat 606 are threaded. The rotation of the first threaded column 602 and the second threaded column 605 will generate a thrust on the guide seat 606, causing the guide seat 606 to move the lifting platform 3 upward. Since the lifting platform 3 is connected to the placement platform 4, the movement of the lifting platform 3 will cause the placement platform 4 to move together. At this time, the first threaded column 602 and the second threaded column 605 are protected by the protective box 613, thereby adjusting the height of the lifting platform 3 to correspond to the actual needs, until the placement platform 4 is close to the oven 2. At this time, the transparent protective plate 614 covers the side of the placement platform 4 facing the staff, thereby providing a certain degree of protection for the staff.

[0023] When the denture needs to be removed after sintering, the servo motor 601 is activated to move the lifting platform 3 downwards. Since the bottom center of the lifting platform 3 is connected to a limiting seat 607, the movement of the lifting platform 3 will cause the limiting seat 607 to move along with it. Because the top sides of the fixed seat 611 have limiting grooves corresponding to the bottom of the limiting seat 607, the lifting platform 3 moves downwards until the bottom of the limiting seat 607 is inserted into the limiting groove. Then, the drive motor 609 is activated to rotate the threaded rod 610. The rotation of the threaded rod 610 then generates a thrust on the fixed seat 611, causing the fixed seat 611 to move the limiting seat 607 closer to the worker. The movement of the limiting seat 607 causes the placement platform 4 to move together, which in turn moves the placement platform 4 closer to the worker along the slide rail 608. Since the fixed seat 611 and the limiting post 612 are slidably connected, the limiting post 612 guides the movement of the fixed seat 611, allowing it to move smoothly until the placement platform 4 moves away from under the oven 2 and gets closer to the worker. At this point, the denture can be removed with tongs. The worker's arm does not need to get too close to the work area to remove the sintered denture, reducing safety hazards. This makes it easy to adjust the height and safely remove the denture when using a porcelain denture furnace designed to prevent burns.

[0024] In summary, when using this anti-scalding porcelain denture furnace, the oven 2 is first placed in the designated position via the base 1, then the denture is placed on top of the placement platform 4, and the denture is then positioned by the clamping component 5. The oven 2 then heats the denture on top of the placement platform 4 to sinter it. This is existing technology and will not be elaborated upon here. The height of the lifting platform 3 is adjusted by the auxiliary mechanism 6 to correspond to actual needs, allowing the placement platform 4 to move upwards closer to the oven 2 for convenient denture sintering, and downwards closer to the fixing seat 611 for convenient denture removal. The placement platform 4 can also be moved away from below the oven 2 to be closer to the worker, at which point the tongs can be used to remove the denture. This allows the worker to remove the sintered denture without their arms getting too close to the work area, reducing safety hazards. Content not described in detail in this specification is existing technology known to those skilled in the art.

[0025] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
