Description

Technical Field

[0001] This utility model relates to the field of porcelain furnace technology, and in particular to a vacuum porcelain furnace for dental prosthesis processing. Background Technology

[0002] With the continuous development of modern oral medicine, dentures (false teeth) are becoming increasingly common in clinical practice as a method of restoring missing teeth. The quality of dentures directly affects the patient's chewing function, comfort, and aesthetics. To improve the durability, strength, and aesthetics of dentures, porcelain fused to metal (PFM) technology is widely used in the denture manufacturing process. PFM technology involves sintering a porcelain layer onto a metal or ceramic substrate, giving the denture not only the strength of metal but also the aesthetics of ceramic. The most important piece of equipment for PFM technology is the porcelain furnace.

[0003] However, existing porcelain furnaces still have certain drawbacks. For example, dentures are usually in a static state when heated, which leads to uneven heating on each side of the denture, thus affecting the porcelain-fused-to-metal effect. Secondly, it is necessary to control not only the opening and closing of the heating components, but also the opening and closing of the lifting and other drive components, making the operation process relatively complicated. Utility Model Content

[0004] The purpose of this invention is to provide a vacuum porcelain furnace for denture processing, which can rotate the dentures in the material tray, so that each side of the denture can be heated evenly, thereby improving the porcelain firing effect, reducing manual operation steps, and simplifying the operation process.

[0005] To achieve the above objectives, a vacuum porcelain furnace for denture fabrication is provided, comprising:

[0014] According to the vacuum porcelain furnace for dental prosthesis processing, the first motor, heating element, temperature controller, first pressure switch, second pressure switch, and second motor are all electrically connected to an external power source.

[0015] The above-mentioned solution has the following beneficial effects:

[0016] 1. By setting up a first touch switch, a second motor and a drive shaft, the denture in the tray can be rotated, so that each side of the denture can be heated evenly, thereby improving the porcelain enamel effect;

A limit groove 21 is provided on the outer surface of the fixed frame 2. The inner surface of the limit groove 21 is adapted to the slider 5. The outer surface of the lead screw 4 is rotatably connected to the fixed frame 2 and the outer surface of the lead screw 4 is rotatably connected to the base 1. The heating element 7 is electrically connected to the temperature controller 8. The temperature controller 8 is electrically connected to the second pressure switch 10. The first pressure switch 9 is electrically connected to the second motor 12. The first motor 3, the heating element 7, the temperature controller 8, the first pressure switch 9, the second pressure switch 10, and the second motor 12 are all electrically connected to an external power source.

[0028] A first contact rod 15 is slidably connected to the inner surface of the bottom frame 11. A first limiting ring 16 is fixedly connected to the outer surface of the first contact rod 15. A first spring 17 is provided on the outer surface of the first contact rod 15. A second contact rod 18 is slidably connected to the inner surface of the bottom frame 11. A second limiting ring 19 is fixedly connected to the outer surface of the second contact rod 18. A second spring 20 is provided on the outer surface of the second contact rod 18.

[0029] Working principle: During operation, the denture is placed in the material tray 14, and then the first motor 3 is started, driving the lead screw 4 to lower the furnace chamber 6 under the action of the slider 5 until the lower surface of the furnace chamber 6 is completely in contact with the upper surface of the bottom frame 11. This ensures that the subsequent porcelain firing is in a sealed heating state, thereby reducing heat loss. When the furnace chamber 6 is in contact with the bottom frame 11, it will press down on the first contact rod 15 and the second contact rod 18, thereby triggering the first contact switch 9 and the second contact switch 10, and stretching the first spring 17 and the second spring 20. At this time, under the action of the second contact switch 10, the temperature controller 8 is activated to control the heating element 7. Heating is performed to heat the dentures in the material tray 14. Under the action of the first touch switch 9, the second motor 12 is started, which in turn drives the dentures in the material tray 14 to rotate through the transmission shaft 13, so that each side of the dentures is heated evenly to improve the porcelain firing effect. After porcelain firing, the first motor 3 is started in reverse, which drives the lead screw 4 to move the furnace chamber 6 upward. At this time, under the action of the rebound force of the first spring 17 and the second spring 20, the first contact rod 15 and the second contact rod 18 will be reset, so that the first touch switch 9 and the second touch switch 10 will be automatically closed. No complicated operation steps are required, which is simple and convenient.

However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
