Description

Technical Field

[0001] The utility model relates to the technical field of artificial teeth processing, in particular to a plaster trimmer for artificial teeth processing. Background Art

[0002] The first step in denture processing is impression making. The doctor needs to use special silicone material to make oral impressions according to the patient's oral condition. This process requires the doctor to operate carefully and patiently to ensure the accuracy and completeness of the impression. Next, the impression needs to be made into a plaster model. The silicone impression is cast into a plaster model. This step requires professional technology and experience to ensure the accuracy and completeness of the model. Then, the denture is designed based on the plaster model. The technician uses computer-aided design software to design the denture according to the patient's oral condition and the doctor's requirements. The designer needs to take into account the patient's bite, tooth shape and color and other factors to ensure the comfort and beauty of the denture. Next, the denture is processed according to the design drawings. Denture processing is usually carried out using CNC machine tools to ensure the precision and stability of the denture. Finally, the denture is debugged and run-in. The doctor will install the processed denture in the patient's mouth to debug the bite and comfort. After ensuring that the denture meets the patient's oral condition and needs, the final running-in and trimming are carried out to ensure the comfort and stability of the denture. In the process of trimming and polishing the denture plaster model, in order to see the actual polishing situation of the denture plaster model, it is often necessary to clean the polishing position. However, the traditional air blowing method can easily cause the debris generated by the grinding to fly everywhere, which is not conducive to the polishing work. Utility Model Content

At this time, the denture plaster is polished by the polishing head.

[0033] Embodiment 2

[0034] This embodiment is disclosed on the basis of the embodiment 1: a closing mechanism is provided at the upper end of the base 1, and the denture plaster surface inside the base 1 is cleaned by closing the base 1;

[0035] The sealing mechanism includes: a transfer chamber 7, the transfer chamber 7 is opened inside the upper end of the side surface of the base 1, and a connecting hole 8 is opened between the transfer chamber 7 and the pressure chamber 4, the upper end of the transfer chamber 7 passes through the upper surface of the base 1, and a sliding airtight ring 9 is installed inside the upper end of the transfer chamber 7;

[0036] The sealing mechanism further includes: an upper cover 10, which is arranged at the upper end of the base 1, and a squeeze ring 11 and a closing ring 12 are fixedly arranged on the lower end surface of the upper cover 10, a flow diversion chamber 13 is opened inside the upper end of the upper cover 10, and the inner surface of the flow diversion chamber 13 is penetrated by the upper end of the flow guide tube 14, and the lower end of the flow guide tube 14 penetrates the lower surface of the upper cover 10 between the squeeze ring 11 and the closing ring 12, a rotating turntable 15 is installed on the inner top surface of the upper cover 10, and a nozzle 16 is fixedly installed on the lower surface of the turntable 15;

[0037] The longitudinal section of the airtight ring 9 is designed in an inverted T-shape, and the outer surface of the lower end of the airtight ring 9 fits the inner top surface of the transfer chamber 7, and a spring is connected between the airtight ring 9 and the inner bottom surface of the transfer chamber 7;
