Centrifugal casting machine for dental denture production

Abstract

The invention discloses an efficient dental denture production centrifugal casting machine, which includes a protective cylinder with an opening on the upper side. The axis of the bottom wall in the protective cylinder is rotatably connected with a rotating cylinder body through a plane bearing, the lower end of the rotating cylinder body is provided with a driving mechanism, and the upper end ofthe rotating cylinder body is internally provided with a molten cavity; and the rotating cylinder body is provided with an annular heating cavity on the outer side of the molten cavity, an electromagnetic coil is wound on the inner wall of the heating cavity, and a feeding hopper is arranged at the upper end of the rotating cylinder body. The efficient dental denture production centrifugal castingmachine has the advantages that a solid alloy located in the molten cavity is heated and melted into a liquid alloy through the electromagnetic coil, central heating is conducted, under driving of adriving mechanism and the action of centrifugal force, a time-delay self-closing valve is opened, and in the time-delay process, the liquid alloy is thrown into an embedding ring in a casting base tocomplete casting; and one casting operation can complete casting of multiple dentures, compared with casting only one at a time in traditional techniques, the number of primary efficiency is increased, and the casting efficiency is greatly improved.

Description

technical field [0001] The invention relates to the technical field of oral machinery, in particular to a centrifugal casting machine for dental denture production. Background technique [0002] The meaning of dentures is to point to the teeth that perform "obligations" for human beings. In medicine, it is a general term for restorations made after partial or complete loss of upper and lower teeth. There are two types of dentures: removable and fixed. Fixed dentures (commonly known as "fixed dentures") cannot be taken and worn by patients themselves, while removable dentures (commonly known as "movable dentures") can be conveniently taken and worn by patients. [0003] Centrifugal casting uses a motor or spring to rotate the rotating machine arm at high speed to generate centrifugal force, and the liquid metal is thrown into the embedding ring in the casting cavity under the action of centrifugal force. The centrifugal casting machine is an ideal equipment for dental tech...

AI Technical Summary

Problems solved by technology

Centrifugal casting machines in traditional technology generally can only cast one denture at a time, and cannot cast multiple dentures at the same time. At the same time, after the casting is completed, the temperature of the casting seat is relatively high, and it can only be cooled after it is cooled by heat exchange with the outside air. Denture removal, this method directly leads to the extension of the casting cycle, and it takes a lot of time to cast a large number of dentures, the casting efficiency is low, and it cannot meet the market demand
