Description

Technical Field

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

[0002] Traditional dental molds for denture fabrication present numerous challenges. For one thing, they are often difficult to remove after the denture prototype has cooled and formed. Forcible removal can easily damage the prototype, significantly impacting denture fabrication efficiency. Furthermore, traditional dental molds cannot be removed smoothly while preserving the integrity of the denture prototype, significantly complicating denture production.

[0003] On the other hand, the cooling efficiency of traditional dental molds is low, which slows down the denture prototype molding process and prolongs the denture processing cycle. The lack of an effective cooling structure prevents the hot melt material from cooling and molding quickly, making it difficult to improve denture production efficiency.

[0004] Furthermore, traditional dental molds lack a good seal. This means that hot melt material can easily leak out during the denture prototype molding process, reducing the success rate of injection molding and affecting the quality of the denture prototype. Poor sealing can lead to inaccurate denture size and shape, making subsequent processing more difficult.

[0005] Finally, the lower mold assembly of traditional dental models lacks stability. During denture production, the various parts of the lower mold can easily loosen, affecting the precision and quality of the denture. This unstable assembly can also lead to problems such as leakage during the injection molding process, further reducing the efficiency and quality of denture production. Utility Model Content
