Description

Technical Field

[0001] The utility model relates to the technical field of denture sintering, in particular to a denture sintering device for denture processing. Background Art

[0002] Dentures are what people often call "false teeth". "Denture" means teeth that fulfill their "duty" for mankind. The production process of dentures requires the use of a special sintering furnace for dentures to sinter the semi-finished dentures.

[0003] According to the existing Chinese patent CN 215766445 U, a sintering furnace for denture processing includes a sintering furnace body, which includes a control box and a sintering chamber. The lower end of the sintering chamber is provided with an opening. A lifting platform is arranged between the control box and the sintering chamber. The lifting platform is slidably connected to the sintering chamber for closing the opening at the lower end of the sintering chamber. A plurality of crucibles for placing dentures are arranged at the upper end of the lifting platform. A rotating disk is arranged between the crucible and the lifting platform. The crucible is arranged at the upper end of the rotating disk. The rotating disk is rotatably connected to the lifting platform. A rotating component for driving the rotating platform to rotate is arranged at the lower end of the lifting platform. This application has the effect of improving the sintering quality of dentures. The device can evenly heat the denture on the crucible in the sintering furnace by placing the crucible on a rotating disk. However, the crucible is inconvenient to take and place when the device is used. When placing the crucible, the positioning blocks need to be aligned with the positioning grooves one by one. When removing the crucible, the crucibles need to be unlocked and removed one by one using the clamping assembly. The steps are cumbersome and time-consuming, resulting in low work efficiency.

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] The utility model provides two technical solutions:

[0025] Figures 1 to 4 The first embodiment is shown: a denture sintering device based on denture processing, comprising a sintering device body 1, a lifting platform 2 is slidably installed on the sintering device body 1, four rotating tables 3 are symmetrically installed above the lifting platform 2, the upper edge of the rotating table 3 is chamfered, and the side walls of the rotating table 3 are symmetrically installed with snap assemblies, the inner wall of the rotating table 3 is clamped with a crucible 4 through the snap assemblies, and a positioning assembly is installed on the lifting platform 2, which enables the eight snap assemblies to simultaneously position the crucible 4 in the rotating table 3.

[0026] The buckle assembly includes a lifting block 5 which is slidably connected to the inner wall of the rotating table 3. The top of the lifting block 5 is inclined and the bottom extends outside the rotating table 3. A first spring 6 is fixedly connected to the side of the outer wall of the rotating table 3 close to the lifting block 5. The end of the first spring 6 close to the lifting block 5 is fixed to the lifting block 5. A second spring 7 is fixed to the inner wall of the rotating table 3. The end of the second spring 7 close to the crucible 4 is fixedly connected to a trapezoidal clamping block 8. The outer wall of the crucible 4 is provided with a circle of clamping grooves 9 corresponding to the trapezoidal clamping block 8.

[0027] This application symmetrically installs a snap assembly on the side wall of the rotating table 3, and opens a circle of snap grooves 9 on the outer wall of the crucible 4 corresponding to the snap assembly. The upper edge of the rotating table 3 is chamfered, so that the operator can place the crucible 4 in the rotating table 3 more conveniently and quickly, which is practical.

[0028] Figures 5 to 7A second embodiment is shown, the main difference from the first embodiment is that the positioning component includes a lifting plate 10 slidably connected to the lifting platform 2, the lifting plate 10 is located below the lifting block 5 and slidably connected to the outer wall of the rotating table 3, and a driving component for driving the lifting plate 10 to rise and fall is installed on the lifting platform 2.

[0029] The driving assembly includes a motor 11 fixed to the inner wall of the lifting platform 2. The motor 11 is a reduction motor. A screw 12 is rotatably connected to the top of the lifting platform 2 through a bearing. The output end of the motor 11 is fixed to the screw 12. The outer wall of the screw 12 is threadedly connected to the lifting plate 10 through a threaded hole.

[0030] This application sets a positioning component and a driving component so that the operator can drive the lifting plate 10 to rise and fall, lift or lower the lifting block 5, and make the eight snap components lock or unlock the crucible 4 at the same time, which saves the operator's effort and improves the production efficiency of dentures.

[0031] Working principle:

[0032] The sintering device body 1 adopts the sintering furnace body in CN 215766445 U, which is the prior art and will not be described in detail.

[0033] When the device is used, four crucibles 4 need to be placed one by one on four rotating tables 3, and then the driving motor 11 drives the screw 12 to rotate so that the lifting plate 10 slides and rises on the outer wall of the rotating table 3, and the lifting plate 10 rises to abut against the bottom of eight lifting blocks 5, and lifts up the lifting blocks 5. At the same time, the first spring 6 is compressed to drive the lifting blocks 5 to slide and rise on the inner wall of the rotating table 3. The lifting blocks 5 rise to the inclined surface at the top of the lifting blocks against the trapezoidal clamping block 8, so that the trapezoidal clamping block 8 moves on the inner wall of the rotating table 3, and the second spring 7 is stretched accordingly until the trapezoidal clamping block 8 is clamped into the clamping groove 9 on the outer wall of the crucible 4, thereby completing the locking of the crucible 4.

[0034] The sintering device body 1 can then be used to sinter the artificial tooth.

[0035] When sintering is completed and the lifting platform 2 is lowered, when the crucible 4 needs to be removed, the driving screw 12 is reversed to make the lifting plate 10 descend, and the lifting block 5 descends under the action of gravity. The first spring 6 rebounds to assist the lifting block 5 to return to its position, and the second spring 7 rebounds to move the trapezoidal block 8 to the inner wall of the rotating table 3, completing the synchronous unlocking of the four crucibles 4, and the crucible 4 can be removed.
