[0031] A denture processing porcelain furnace, comprising a cabinet 1 and a heating box 6 installed on the upper side of the cabinet 1;

[0032] A loading plate 4 is provided on the upper side of the cabinet 1;

[0033] A heating dish 5 is provided on the upper side of the loading plate 4;

[0034] A heater 10 is provided inside the heating box 6. A porcelain slot 12 is provided on the lower side of the heater 10 for inserting the heating dish 5 for porcelain baking operation. An operation screen 3 is embedded inside the front outer wall of the cabinet 1. The operator places the heating dish 5 on the loading plate 4 and puts the denture material to be baked into the heating dish 5. The required porcelain baking temperature and time are set through the operation screen 3. After the heater 10 is powered on, it starts to operate and heats the porcelain slot 12 and the heating dish 5 therein by heat radiation and convection. The heat is evenly distributed on the heating dish 5, so that the material reaches the required high temperature state, thereby achieving the porcelain baking effect. Within the set time, the heater 10 continues to work to ensure that the denture material is fully heated and cured, while ensuring the molding effect of the porcelain. After the porcelain baking process is completed, the operator stops the heater 10 through the operation screen 3;

[0035] The rear end outer wall of the loading plate 4 is provided with a fixing plate 7, and a slot 15 is opened inside the front end outer wall of the fixing plate 7. The rear end outer wall of the loading plate 4 is fixedly connected with an inserting plate 14 that penetrates backward into the slot 15 to pre-limit the position of the loading plate 4. When the heating dish 5 needs to be taken out, the loading plate 4 can be pulled outward so that the inserting plate 14 at the rear end of the loading plate 4 is pulled out from the slot 15 inside the fixing plate 7, and the loading plate 4 and the heating dish 5 can be removed simultaneously, avoiding the situation that the heating dish 5 falls off when the heating dish 5 is clamped alone to be taken out. When the heating dish 5 is taken out alone for cooling, the same loading plate 4 and heating dish 5 can be taken again, and the loading plate 4 can be reinserted into the fixing plate 7, and the porcelain baking operation can be performed again, thereby increasing work efficiency.

[0036] Please refer to Figure 3 A threaded hole 16 opening to the right is provided on the inner wall of the left end of the slot 15, and a through opening 19 is provided on the inner wall of the right end of the slot 15 and the inside of the insert plate 14. A threaded rod 17 is inserted between the two through openings 19 and the threaded hole 16, and an adjusting nut 18 is fixedly connected to the outer wall of the right end of the threaded rod 17.

[0037] After the loading plate 4 is inserted into the fixing plate 7 , the threaded rod 17 can be inserted to the left into the through opening 19 and the threaded hole 16 , and the adjusting nut 18 can be rotated to screw the threaded rod 17 and the threaded hole 16 together to fix the position of the loading plate 4 .

[0038] Please refer to Figure 3 , a thread is provided on one side where the threaded rod 17 and the threaded hole 16 are screwed together, and the adjusting nut 18 can rotate clockwise and counterclockwise under the action of external force.

[0039] The threaded rod 17 and the threaded hole 16 are screwed together only on one side thereof, which speeds up the insertion speed of the threaded rod 17 into the through-port 19 and the screwing speed, thereby speeding up the fixing speed between the loading plate 4 and the fixing plate 7. The threaded rod 17 and the threaded hole 16 can be screwed together by rotating the adjusting nut 18 clockwise, and the threaded rod 17 and the threaded hole 16 can be separated by rotating the adjusting nut 18 counterclockwise.

[0040] Please refer to Figure 4 A scalding prevention cover 20 is provided on the upper side of the heating dish 5. Pressure rods 23 are provided inside the circular outer walls at both ends of the anti-scalding cover 20 to abut the circular outer wall of the heating dish 5. Limiting grooves 21 are provided inside the circular outer walls at both ends of the anti-scalding cover 20 to limit the movable distance of the pressure rods 23. One end of the two pressure rods 23 is fixedly connected to a pressure plate 22.

[0041] When removing the heating dish 5 from the loading plate 4, the heating dish 5 which is still hot can be removed without the aid of a clamping tool. The anti-scalding cover 20 is placed on the heating dish 5, and then the pressing plate 22 is held and pressed inward so that the pressing rod 23 abuts against the heating dish 5 to increase friction. The heating dish 5 can then be moved by gripping.

[0042] Please refer to Figure 4 The lateral lengths of the two pressure rods 23 are greater than the lateral length of the limiting groove 21. The upper and lower outer walls of the two pressure rods 23 are provided with latching teeth, and the upper and lower inner walls of the two limiting grooves 21 are provided with multiple limiting teeth.

[0043] The pressure rod 23 is relatively long, and the movable distance of the pressure rod 23 provided ensures that the pressure rod 23 can stably abut against the circular outer wall of the heating dish 5, increasing the friction during grasping. When the pressure rod 23 moves left and right, the abutment between the latch teeth and the limiting teeth inside the limiting groove 21 limits the movable range of the pressure rod 23.

[0044] Please refer to Figure 1 and Figure 2 A guide rail 8 is fixedly connected between the cabinet 1 and the heating box 6, and a slide groove 9 is opened inside the front outer wall of the guide rail 8. A stepper motor 13 is provided inside the heating box 6, and a heat conduction groove 11 is provided inside the heater 10 to evenly transfer heat. A power switch 2 is provided on the right end outer wall of the cabinet 1, and a power module is provided inside the cabinet 1 to provide power for the operation screen 3, the heater 10 and the stepper motor 13.

[0045] The operator turns on the equipment through the power switch 2, and the power module immediately supplies power to the operation screen 3, the heater 10 and the stepper motor 13, so that the equipment is ready for work. When the heater 10 is powered on, the generated heat is effectively transferred to the heating dish 5 through the heat conduction groove 11, so that it reaches the required porcelain temperature. Through the operation screen 3, the operator can monitor the status of the heating box 6 in real time and set the required temperature and time. The specific parameter settings directly affect the effect of the porcelain. When the position of the heating dish 5 needs to be adjusted, the stepper motor 13 can drive the fixed plate 7 to move up and down under the restriction of the slide groove 9, so that the heating dish 5 can stably enter the interior of the porcelain groove 12.

[0046] The implementation principle of this embodiment is as follows: the operator places the heating dish 5 on the carrier plate 4 and puts the denture material to be porcelain-baked into the heating dish 5, and sets the required porcelain baking temperature and time through the operation panel 3. After the heater 10 is powered on, it starts to operate and heats the porcelain baking tank 12 and the heating dish 5 therein by heat radiation and convection. The heat is evenly distributed on the heating dish 5, so that the material reaches the required high temperature state, thereby achieving the porcelain baking effect. Within the set time, the heater 10 continues to work to ensure that the denture material is fully heated and solidified, while ensuring the molding effect of the porcelain. After the porcelain baking process is completed, The operator stops the heater 10 through the operation panel 3. When the heating dish 5 needs to be taken out, the operator can pull out the carrier plate 4 so that the insert plate 14 at the rear end of the carrier plate 4 is pulled out from the slot 15 inside the fixed plate 7. The carrier plate 4 and the heating dish 5 can be taken out simultaneously, avoiding the situation where the heating dish 5 falls off when the heating dish 5 is clamped and taken out separately. When the heating dish 5 is taken out separately for cooling, the same carrier plate 4 and heating dish 5 can be taken out again, and the carrier plate 4 can be reinserted into the fixed plate 7. The porcelain baking operation can be carried out again, thereby increasing work efficiency.
