  • Patent number: 4979338
    Abstract: A cryogenic deflashing apparatus is disclosed specifically adapted to rapidly remove residual flash from molded articles. The cryogenic deflashing apparatus incorporates a novel throw wheel assembly formed as a pump to create a vacuum utilized to continuously recirculate blasting media within the deflashing chamber. The throw wheel is powered by a pneumatic motor the exhaust of which is supplied to the intake port of the throw wheel to pre-accelerate the blasting media onto the throw wheel as well as supplement the magnitude of vacuum lift of the blasting media into the throw wheel. An article basket and basket drive mechanism is disposed within the deflashing chamber and includes biasing seal means for eliminating article spillover during the deflashing operation as well as facilitating ease in removal and insertion of the article basket within the deflashing chamber.
