[0002] Dentures are what people often call "false teeth". Zirconia dentures have the advantages of preventing tooth sensitivity, being beautiful, not irritating the gums, and not generating magnetic fields. The disadvantages include brittle texture of the crown and poor wear resistance. The common ceramic blocks used for zirconia denture processing are made by mold molding.

[0003] At present, the zirconia ceramic block forming mold is composed of an upper mold and a lower mold. Although the upper mold can be raised and lowered on the lower mold to achieve mold closing and mold opening, the upper mold is still above the lower mold after mold opening, which causes the upper mold to hinder the demolding operation of the zirconia molded in the lower mold. The demolding operation space is small, and the zirconia ceramic block is molded in the molding groove of the lower mold core, which makes it inconvenient to demold and remove. Utility Model Content
