COOLING STRUCTURE OF METAL-MOLDING SYSTEM FOR SHOT LOCATED DOWNSTREAM OF BLOCKAGE

摘要

Disclosed is a metal molding system comprising a conduit passageway conne cted to a mold, and a cooling structure which cools molten metal in the pass ageway to form a blockage such as a plug. The blockage may be upstream of a volume of molten metal. In a metal molding process, the volume of molten met al is injected into the mold.
