Manual-automatic injection molding machine for denture

Abstract

The invention discloses a manual-automatic injection molding machine for a denture. The machine includes a base, a shell and an electrical control box, and the electrical control box is installed on the shell; the base is in a rectangular parallelepiped shape and is placed horizontally, a horizontally placed pressure air cylinder for providing fully automatic injection molding pressure is installed at the left end part of the base, the end part of a piston rod of the pressure air cylinder is provided with a heater for heating and melting a resin material to be injected to a certain temperature; the part, corresponding to the right end surface of the heater, of the base is provided with a model box groove extending upward for installing and fixing a dental model box and facilitating injecting molten resin to the denture in the dental model box; a locking device for pushing the dental model box in the model box groove to be tightly connected to the end surface of the right side wall of the heater is installed at the right end part of the base; and the dental model box in the model box groove is tightly fixed to the right side wall of the heater by the locking device, and the heater and pressure air cylinder are automatically controlled by the electrical control box to continuously inject the molten resin material into the denture in the dental model box.

Description

【Technical field】 [0001] The invention relates to denture processing technology, in particular to a manual and automatic denture injection machine. 【Background technique】 [0002] Dentures are artificial teeth that replace missing natural teeth, also known as dentures. Severe periodontal disease, dental caries and trauma can cause partial or even complete loss of teeth. Dentures need to be installed to help people complete functions such as chewing; denture injection molding is the process of dentures. In the production process of the denture, the production material needs to be heated to a certain temperature, extruded into the denture model, and taken out after cooling down and solidifying. For traditional denture molding, generally, the resin particles are heated and melted first, and then manual molding is used. After the adhesive is manually heated to a certain temperature, it is poured into the mold and injected into the dental mold for injection molding. The molding p...

Problems solved by technology

For traditional denture molding, generally, the resin particles are heated and melted first, and then manual molding is used. After the adhesive is manually heated to a certain temperature, it is poured into the mold and injected into the dental mold for injection molding. The molding process The equipment used is simple, but the operation is cumbersome, and the temperature and pressure are difficult to control, resulting in low product accuracy and efficiency, and difficult to guarantee the quality, which limits the service life of the manufactured dentures.

[0003] At present, the existing denture molding machines in China include screw injection equipment and hydraulic screw dual-purpose equipment; whether it is the upper three-handle screw type or the lower hydraulic jack injection equipment, they are all based on manual force, and the pressure cannot be accurate. Control, uneven movement, incomplete injection pressure, easily crushed operating rod, crushed tooth box
