Casting porcelain furnace

Abstract

The invention relates to the field of dental equipment, and discloses a casting porcelain furnace. The casting porcelain furnace includes a base which is used as a bearing structure, a furnace cover,a furnace seat, a heating device, a punching rod and a punching rod driving assembly. The furnace cover is sealed with the furnace base to form an insulated furnace chamber, and a through hole, in communication with the furnace chamber, is formed in the furnace cover. The furnace seat and / or the furnace seat are provided with an air exhausting hole which is in communication with the furnace chamber. The heating device is used to heat the furnace chamber. The punching rod is inserted in the through hole in a sealed mode. The punching rod can exert pressure on material which is to be processed under the driving of the punch rod driving assembly. The high temperature and vacuum environment can be provided in the casting process through the coordination of the furnace seat, the furnace cover,the heating device, the punching rod and the punching rod driving assembly. At the same time, a casting material can be exerted pressure, so that the industrialized production of cast porcelain teethis achieved. The casting porcelain furnace is convenient to use and high in reliability.

Description

technical field [0001] The invention relates to the field of automation equipment, in particular to the field of dental equipment, in particular to a ceramic casting furnace. Background technique [0002] With the development of technology, cast porcelain teeth have become more and more widely used in the dental field. Cast porcelain teeth, also known as cast ceramic crowns, are made of castable ceramic materials. Different from traditional metal porcelain teeth, the color of cast porcelain teeth is closer to real teeth. At the same time, cast porcelain teeth do not contain metal, which can avoid the stimulation of the gums by the metal inner crown of porcelain teeth. [0003] Cast porcelain teeth need to be molded in a high temperature and vacuum environment, and at the same time, a certain amount of pressure needs to be applied during the casting process. There is still a lack of cast porcelain teeth casting that can integrate the above heating, vacuuming and pressure in t...
