A mold for manufacturing medical mask airbags

Abstract

The invention provides a mold for manufacturing medical face mask airbags, comprising: an upper mold, with an upper molding cavity around it, the middle part runs through up and down, and a locking plate is provided in the middle; The upper molding cavity is matched with the lower molding cavity. One end of the lower molding cavity is provided with an air nozzle. blocks corresponding to the two ends of the locking plate; and a locking mechanism, the locking mechanism is used to lock the locking plate and the locking block, and then connect the upper mold The mold is locked. The sealing performance of the mold is very good, which can prevent the mask slurry from overflowing, has the advantages of no edge material, no slurry return, the surface of the mold is kept clean, and the process is reduced to improve product quality.

Description

technical field [0001] The invention relates to the field of molds, in particular to a mold for manufacturing medical mask airbags. Background technique [0002] At present, disposable anesthesia devices are one of the essential medical device products for surgical operations. In recent years, the domestic and foreign disposable anesthesia equipment market has grown rapidly, and medical masks are one of them. Existing technology, the mold that produces medical mask air bag is made up of parts such as upper mold and lower mold. When producing mask airbags, the existing technology is to first place the lower mold horizontally, then pour an appropriate amount of mask slurry into the lower mold, and at the same time fill the upper mold with mask slurry, then turn the upper mold 180 degrees to make the excess The mask slurry flows out, and then the upper mold is covered on the lower mold, and the upper and lower molds are combined and placed in a high-temperature furnace for ba...

AI Technical Summary

Problems solved by technology

[0003] Existing technology, the above-mentioned method for producing mask airbag has the following problems: After the upper mold and the lower mold are all poured into the slurry and the mold is closed, due to the upper mold and the lower mold The lower mold cannot be completely sealed, so the slurry inside will overflow from the gap between the upper mold and the lower mold. After the overflowing slurry is formed at high temperature, excess trimmings will be produced, so the trimming of trimmings will be increased. process

Finally, when recycling the excess slurry that overflowed after the upper mold was turned 180 degrees, because the slurry is mixed with black slag and impurities that fell off the surface of the mold, this will greatly affect the quality of the product and increase the scrap rate of the product
