A control panel is embedded in the upper front side of the control console. A sintering furnace body is connected to the upper right side of the control console. A placement cavity is located at the top of the sintering furnace body, and a placement base plate is located at the bottom of the placement cavity. A heat dissipation seat is fixedly mounted on the top of the placement base plate. Air inlet slots are evenly spaced around the inner wall of the heat dissipation seat. A first filter screen is fixedly mounted inside the air inlet slots. Multiple sets of cooling fans are installed to draw air in through the air inlet slots and blow it upwards through the air outlets, forming a ring-shaped upward airflow around the sintering plate inside the sintering furnace body. This quickly removes surrounding heat and promotes gas flow in the middle of the placement cavity, achieving a good heat dissipation effect. This can shorten the waiting time after the sintering of zirconia all-ceramic teeth is completed, improve production efficiency, and facilitate the promotion of this utility model.

[0004] Based on the aforementioned existing technology, the existing zirconia all-ceramic dental sintering furnace still has the following problems: after sintering, the finished product needs to be removed from the existing zirconia all-ceramic dental sintering furnace. However, if the heat inside the sintering furnace is not completely dissipated during the removal process, it may cause injury to the hands of personnel. Therefore, this utility model provides a zirconia all-ceramic dental sintering furnace. Summary of the Invention

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please refer to Figures 1-4. This utility model provides a technical solution:

[0025] A zirconia all-ceramic dental sintering furnace includes a furnace body 1. The furnace body 1 has a pull-out mechanism 2 inside for pulling out and retrieving zirconia all-ceramic teeth. The pull-out mechanism 2 includes:

[0026] The sliding unit 21 is located inside the sintering furnace body 1 and includes a lifting seat 211 that is lifted and installed inside the sintering furnace body 1. A set of sliding grooves 212 are provided on the inner wall of the lifting seat 211. A slider 213 is slidably installed inside the sliding grooves 212. A sliding plate 214 is fixedly installed on the inner side of the slider 213, and a placement cavity 215 is fixedly installed on the top of the sliding plate 214. The sliding plate 214 slides back and forth inside the lifting seat 211 through the slider 213 to realize the pulling out and taking out of the zirconia all-ceramic tooth.

[0027] Positioning unit 22 is disposed inside the positioning unit 22 and is used to limit the position of sliding plate 214;

[0028] Space unit 23 is disposed inside positioning unit 22 and is used to create space for pushing sliding plate 214.

[0029] In this embodiment, a positioning groove 216 is provided at the bottom of the sliding plate 214, and a slot 217 is provided at the bottom of the sliding plate 214, and the positioning groove 216 and the slot 217 are connected.

[0030] Users pull the sliding plate 214 by the handle on the front of the sliding plate 214. The sliding plate 214 slides in the groove 212 through the slider 213, realizing the back and forth movement, thereby moving the placement cavity 215 out of the sintering furnace body 1, thus avoiding damage to the hands of personnel when handling zirconia all-ceramic teeth inside the sintering furnace body 1.

[0031] In this embodiment, the positioning unit 22 includes a track plate 222 fixedly installed inside the lifting seat 211. A rotating shaft 229 is rotatably installed inside the track plate 222. A gear 221 and a rotating rod 2211 are fixedly installed on the surface of the rotating shaft 229. The rotating rod 2211 is inserted into the slot 217 to fix the position of the sliding plate 214. A trapezoidal groove 223 is opened inside the track plate 222. A trapezoidal block 224 is slidably installed inside the trapezoidal groove 223. A rack 225 is fixedly installed on the top of the trapezoidal block 224. The rack 225 is meshed with the gear 221.

[0032] When the user pulls the lever 227, the lever 227 moves the rack 225, which in turn drives the gear 221 to rotate. The gear 221 then drives the rotating rod 2211 to rotate synchronously via the rotating shaft 229. The rotating rod 2211 pushes the sliding plate 214 to press the second mounting plate 233 against the pressure spring 232. The rotating rod 2211 then moves out of the slot 217, thereby fixing the position of the sliding plate 214.

[0033] In this embodiment, a fixing plate 226 is fixedly installed inside the track plate 222, and a pull rod 227 is slidably installed in the through hole inside the fixing plate 226. A limit ring 228 is fixedly installed on the surface of the pull rod 227, a spring 2210 is sleeved on the surface of the pull rod 227, and one end of the pull rod 227 is fixedly connected to the rack 225.

[0034] The all-ceramic tooth to be sintered is placed inside the placement cavity 215. The sliding plate 214 is pushed, and the rear end of the sliding plate 214 contacts the rotating rod 2211, causing the rotating rod 2211 to rotate. The rotating rod 2211 drives the gear 221 to rotate through the rotating shaft 229. The gear 221 drives the rack 225 to move. The rack 225 compresses the spring 2210, and the rotating rod 2211 slides into the positioning groove 216. The spring 2210 pushes the rack 225 through its own elasticity, and the rack 225 drives the gear 221 to rotate. The gear 221 drives the rotating rod 2211 to rotate synchronously through the rotating shaft 229. The gear 221 is engaged in the slot 217, fixing the position of the sliding plate 214. The sintering furnace body 1 is started, which drives the lifting seat 211 to rise for sintering.

[0035] In this embodiment, the space unit 23 includes a first mounting plate 231 fixedly installed on the rear side of the inner cavity of the lifting seat 211. A compression spring 232 is fixedly installed on one side of the first mounting plate 231, and a second mounting plate 233 is fixedly installed on one end of the compression spring 232.

[0036] Gear 221 drives rotating rod 2211 to rotate synchronously via rotating shaft 229. Rotating rod 2211 pushes sliding plate 214 to press second mounting plate 233 and pressure spring 232, thereby enabling sliding plate 214 to have a moving space.

[0037] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0038] During operation, firstly, the user pulls the lever 227, which drives the rack 225 to move. The rack 225 drives the gear 221 to rotate, and the gear 221 drives the rotating rod 2211 to rotate synchronously through the rotating shaft 229. The rotating rod 2211 pushes the sliding plate 214 to press the second mounting plate 233 and the pressure spring 232, and the rotating rod 2211 moves out of the slot 217.

[0039] Then, the user pulls the sliding plate 214 through the handle on the front side of the sliding plate 214. The sliding plate 214 slides inside the slide groove 212 through the slider 213, so that the placement cavity 215 is moved out of the sintering furnace body 1 and the finished product sintered inside the placement cavity 215 is taken out.

[0040] Finally, the all-ceramic tooth to be sintered is placed inside the placement cavity 215, and the sliding plate 214 is pushed. The rear end of the sliding plate 214 contacts the rotating rod 2211, causing the rotating rod 2211 to rotate. The rotating rod 2211 drives the gear 221 to rotate through the rotating shaft 229. The gear 221 drives the rack 225 to move. The rack 225 compresses the spring 2210, and the rotating rod 2211 slides into the positioning groove 216. The spring 2210 pushes the rack 225 through its own elasticity, and the rack 225 drives the gear 221 to rotate. The gear 221 drives the rotating rod 2211 to rotate synchronously through the rotating shaft 229. The gear 221 is engaged in the slot 217, fixing the position of the sliding plate 214. The sintering furnace body 1 is then started for sintering.
