Description

Technical Field

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

[0002] During the production process of dentures, they need to be porcelainized. When porcelainizing, you need to first mix porcelain powder and water into a paste, then stack the denture according to the measured shape of the teeth, and finally put the stacked denture into a sintering furnace for sintering and cool it after sintering. Since the surface temperature of the denture is very high after sintering, it needs to be carried and placed on a designated workbench for cooling. Currently, clamps are used to manually clamp it to a designated position for cooling. In the existing technology, the current publication number is CN214923601U, a clamp and smelting device, which records: the clamp includes The invention comprises two mutually hinged clamp arms and two clamping members, the clamping members having an inner conical surface for clamping a clamping target, and the inner conical surfaces of the two clamping members are arranged opposite to each other. When the clamp is in a clamping state, the two clamp arms are closed, and the inner conical surfaces of the two clamping members clamp the two sides of the clamping target respectively. The inner conical surfaces are easy to form surface contact with the side surfaces of the clamping target, and the contact area is large. The clamping friction force on the clamping target is large and the pressure is small. The clamping is reliable and not easy to deform. The inner conical surface can provide an upward supporting force to the clamping target, thereby improving the reliability of clamping.

[0003] In the prior art, as recorded in the above-mentioned documents, during the denture manufacturing process, the denture needs to be placed in a crucible sintering container for sintering, and then clamped out with pliers after sintering. Since the length of the pliers arms of the existing pliers are fixed, they cannot be fully adapted to pliers pot sintering containers of different sizes, and have great limitations. In addition, the pliers arms are too short, which may cause burns to the staff when clamping out, thus posing certain safety hazards. Utility Model Content
