DEVICE FOR PRESSURE CASTING

摘要

A pressure die casting method and apparatus wherein the delivery tube from the melt reservoir contained in the pressurizable housing can receive the melt on the tube affixed to the mold which also is in a pressurizable housing and when the latter tube is retracted from the former, a sliding shutter closes the top of the reservoir tube. Gas communication between the upper end of the reservoir tube and the interior of the housing is permitted to ensure that a gas layer corresponding to that in the housing will overlie the melt in the reservoir portion of the tube.
