摘要： Apparatus for the gravity-cast, bottom-fill, “lost foam” casting of metal castings, including a fugitive, pyrolizable pattern (for forming a casting cavity), and a hollow sprue (for conducting melt to the casting cavity) embedded in a bed of loose sand. The sprue is free from pyrolyzable foam and conducts melt from above the pattern to a gating system supplying melt to the pattern. The sprue is constructed so as to cause the melt to approach the gating system from beneath and keep any pyrolysis products from entering the sprue.

摘要： A method and machine for forming an open riser in a mold includes a resiliently compressible plug received into the upper end of a riser sleeve, which projects above the riser sleeve and cope sand level so as to be advanced into the riser sleeve during squeezing of the mold sand. The plug is fixed to the upper squeeze plate to be withdrawn from the riser sleeve as the squeeze plates are separated, creating an open riser.

The riser sleeve further includes an annular lip (20) which is positioned adjacent the second end and extends inward into the passage. When the riser sleeve is positioned about a plug of a pattern, the annular lip deforms to seal the passage at the second end. A process for forming a cast metal article using said riser sleeve apparatus. A process for forming the riser sleeve apparatus.

摘要： A reduction casting method, in which a molten metal is poured into a cavity of a molding die and casting is performed while the oxide film formed on the surface of the molten metal is reduced by allowing the molten metal and the reducing compound to be contacted with each other in the cavity of the molding die, is characterized in that, at the time the molten metal is poured into the cavity, it is done while it is allowed to be in a turbulent flow.

摘要： A riser sleeve has a sleeve body and an evaporative pattern fit into the sleeve body to pass through a side wall thereof. The evaporative pattern is shaped to enable the casting, integrally with the riser cast by the sleeve body, of a projecting portion capable of receiving a wedge blade of an openable wedge blade type riser breaker. Even a top riser can therefore be broken off of the main casting at a neck portion by an opening force applied to the wedge blades of the riser breaker without the use of a special jig.

摘要： Apparatus and methods of die casting which reduce waste, by providing heated channels to feed solidification shrinkage. The channels are heated to a temperature which prevents solidification in the channels, thus allowing the channels to be substantially smaller than conventional risers. An insulating layer in the mold prevents excessive heat loss from the channels to the mold cavity area.
