Claims17
A casting furnace for low pressure casting comprising a furnace chamber and an insert for receiving a melt, said insert at least partially disposed within the furnace chamber such that a portion of the insert is in contact with the melt, the insert including a valve for controlling a flow of melt from the furnace into the insert, a riser for feeding melt from the insert into a mold, and a channel for supplying and/or discharging gas into and out of the insert, wherein the valve is comprised an elongated body defining a passage and a post disposed in said passage, said post including a top end wider than said passage and a bottom end wider than said passage.
A casting furnace for low pressure casting comprising a furnace chamber and an insert for receiving a melt, said insert is at least partially disposed within the furnace chamber such that a portion of the insert is in contact with the melt, the insert including a valve for controlling a flow of melt from the furnace into the insert, a riser for feeding melt from the chamber into a mold, and a channel for supplying and/or discharging gas into and out of the insert, wherein the insert includes a rim extending from a cup-shaped body, and wherein the lower most intersection between the rim and cup-shaped body is a curved surface, and wherein a bottom wall of the cup-shaped body includes a curved surface at an intersection of a side-wall of the cup-shaped body and the bottom wall.
