Description

Technical Field

[0001] The utility model relates to the technical field of sintering furnaces, in particular to a lifting denture sintering furnace. Background Art

[0002] After the denture is sintered, it needs to be carried to a designated location for cooling. However, since the surface temperature of the denture is high when it is just sintered, it is very likely that the high-temperature denture will accidentally touch others and cause burns when it is carried to the designated location for cooling. In addition, the denture may be accidentally dropped on the ground during the process of carrying it, causing damage to the denture.

[0003] The prior art CN207945975U includes a control panel, a driving device, a sintering device, a workbench and a resistance wire. When sintering the denture, first operate the control panel to control the driving device to drive the sintering device to move downward until the sintering device covers the workbench. Then turn on the heating switch on the control panel, and the resistance wire in the sintering device releases heat after being powered on, so as to sinter the denture placed therein. When the denture is sintered, take the denture out and place it on the workbench for cooling. Due to the setting of the workbench, the staff does not need to carry the sintered denture to other locations for cooling, thereby avoiding accidentally touching the high-temperature denture to others while carrying the denture to the designated location for cooling, thereby avoiding accidentally dropping the denture on the ground while carrying the denture, thereby damaging the denture.

[0004] When sintering a denture, the denture needs to be placed in a crucible. The weight of the sintering device is generally greater than the weight of the crucible. However, in the prior art, when sintering a denture, it is very inconvenient to move the sintering device to allow the denture to enter the sintering device, which reduces the practicality of the device.
