Abstract

The invention discloses a vacuum light curing machine. The curing machine includes a curing cabin, the curing cabin includes a shell, a hatch cover, an inner tank and an inner cover matched with the inner tank, the inner tank is provided with an ultraviolet lamp and a tray, and the bottom of the housing is provided with an upward first protrusion Its top is provided with a downward second protrusion corresponding to the first protrusion, and corresponding grooves are opened in the first protrusion and the second protrusion, and the inner liner is embedded in the groove Inside, a nitrogen injection port is also opened above the interior, and an escape port is also opened on the hatch cover. The vacuum light curing machine of the present invention has a good sealing effect by embedding the liner in the corresponding grooves of the first protrusion and the second protrusion, and can save nitrogen, and the object to be cured can be protected from being damaged during the curing process by nitrogen. Oxidized to eliminate the antagonism of oxygen in photocuring.

Description

technical field [0001] The invention relates to a light curing machine, in particular to a vacuum light curing machine. Background technique [0002] Existing ear molds for hearing aids are divided into two types: hard ear molds and soft ear molds. Once the hard ear molds are made, the shape cannot be changed. The ear is prone to damage when it is stressed. Its airtightness is not as good as that of soft ear molds, and it is only suitable for mild, moderate, and severe hearing-impaired patients. However, it has better durability and plasticity, can be made into various shapes, and its acoustic characteristics are easy to adjust. In addition, the price is relatively cheap, and it is the most widely used type in China at present. [0003] The material of the hard ear mold can use ultraviolet light curing ear mold material, which is based on the polymer containing vinyl, the active monomer is used as the crosslinking agent, and the compound that is easy to photodecompose is u...
