Title:
CONTINUOUS, PRESSURIZED MOLD FILLING PROCESS AND CASTING MACHINE FOR MAKING AUTOMATIVE AND AEROSPACE COMPONENTS
Document Type and Number:
WIPO Patent Application WO2003002285
Kind Code:
A3
Abstract:
Mold filling and feeding device (400) and process including using refractory filter cloth (202) to seal a mold line (100), in continuous conveyance, to a multi-stage pressurized filling and feeding device. The mold line (100) is the line formed of vertically parted green sand molds (101). These molds can be filled with molten metal which gradually solidifies under pressure. Feeding under pressure will assist shrinkage problems in the casting process. The process includes modes of treating ductile iron with magnesium for compacted graphite. A stitch (242) of filter cloth (202) holds modifying alloy (630) to the molds (101) at high speed. A vacuum and pressure controlled column (550) provides consistent flow to thin walled castings, and pressurized feeding for heavy castings. Radiant energy losses are contained in the automatic system. The process and several special purpose machine components make a unified system for hardening liquid (600) such as plastic polymer, rubber tires, or food stuff, as in molded chocolate candy.
