Abstract
A foundry flask includes at least three discrete corner sections and at least three discrete side sections wherein the yield strength of the corner sections is greater than the yield strength of the side sections. Each one of the corner sections is connected to a pair of the side sections so as to form a foundry flask section that has at least three sides. The foundry flask further includes a bottom member that is connected to the foundry flask section.
Claims18
A foundry flask comprising:
- at least three discrete corner sections;
- at least three discrete side sections;
- each one of the corner sections being connected to a pair of the side sections so as to form a foundry flask section having at least three sides;
- and
- a bottom member connected to the foundry flask section.
A foundry flask comprising:
- at least three discrete corner sections, each one of the corner sections having a first tensile strength;
- at least three discrete side sections, each one of the side sections having a second tensile strength, and the first tensile strength being greater than the second tensile strength;
- each one of the corner sections being connected to a pair of the side sections wherein the corner section is mediate of the pair of the side sections, the corner sections and the side sections when connected together form a foundry flask section;
- and
- a bottom section connected to the foundry flask section.
A foundry flask section for use with a bottom member to form a foundry flask, the foundry flask section comprising:
- at least three discrete corner sections, each one of the corner sections having a first tensile strength and a first yield strength;
- at least three discrete side sections, each one of the side sections having a second tensile strength and a second yield strength, and the first tensile strength being greater than the second tensile strength, and the first yield strength being greater than the second yield strength;
- each one of the corner sections being connected to a pair of the side sections wherein the corner section is mediate of the pair of the side sections.
A corner section for use with one or more discrete side sections and a bottom section in a foundry flask wherein the corner section cooperates with a lifting member to move the foundry flask, the cast corner section comprising:
- a body having a mediate portion, and a pair of distal portions integral with the mediate portion, and wherein each distal portion extends away from the mediate portion;
- the mediate portion and the integral distal portions defining an interior surface of the body and an exterior surface of the body;
- the exterior surface of the body containing a channel;
- and
- an integral projection projecting from the exterior surface of the body.
