Description

Technical Field

[0001] The utility model relates to the technical field of artificial teeth production, in particular to a sintering device used for artificial teeth production. Background Art

[0002] Dentures are what people often call "false teeth". Just like "false legs" and "false limbs" are called "artificial limbs", "dentures" mean teeth that fulfill "duties" for humans. In medicine, it is a general term for restorations made after partial or complete tooth loss in the upper and lower teeth. Dentures are divided into removable and fixed. Fixed dentures (commonly known as "fixed dentures") cannot be removed and put on by the patient himself, while removable dentures (commonly known as "removable dentures") can be easily removed and put on by the patient.

[0003] After searching, the Chinese patent publication number CN209570014U discloses a denture sintering device, including a workbench, a sintering furnace is arranged on the workbench, the bottom of the sintering furnace is open and a feeding port connected to the opening is arranged on the side close to the operator, a loading plate that can close the opening is slidably arranged in the sintering furnace, a receiving groove is arranged on the loading plate, a receiving plate is slidably arranged in the receiving groove, and a closing plate that closes the feeding port is slidably connected to the side wall of the sintering furnace. The above patent has the following shortcomings: the existing denture sintering devices generally sinter each denture separately, and cannot sinter multiple dentures at the same time, thus causing a certain waste of resources and increasing production costs. At the same time, during the sintering process, the tooth-shaped blanks are heated unevenly and the defective rate is high. In view of this, we propose a sintering device for denture production.
