Abstract
To cast one or more metal articles, a mold structure is positioned on a support with an anchor extending upward from the support into the mold structure. The mold structure and anchor are interconnected by a retainer which extends through a portion of the mold structure into the anchor. When the mold structure is immersed in a cooling bath, force is transmitted between the mold structure and anchor to retain the mold structure against movement relative to the support.
Claims21
A method of casting metal articles, said method comprising the steps of providing a support, positioning a mold on the support with an anchor extending upward from the support into the mold, interconnecting the mold and the anchor with a retainer member which extends through a portion of the mold into the anchor, at least partially filling the mold with a molten metal while the mold is disposed on and is supported by the support, thereafter, at least partially immersing the mold in a bath, and transmitting force between the mold and the anchor to retain the mold against movement relative to the support during performance of said step of immersing the mold in a bath.
A method of casting metal articles, said method comprising the steps of providing a support having an anchor extending upward from an upper side of the support, providing a mold having a base plate with an opening which extends through the base plate and having a plurality of article molds extending upward from the base plate at locations spaced from the opening which extends through the base plate, positioning the base plate of the mold on the support with the anchor extending through the opening in the base plate and with portions of the base plate disposed between the article molds and the anchor, thereafter, moving a retainer member through a portion of the mold into the anchor to interconnect the mold and the anchor while the anchor extends through the opening in the base plate and while the base plate is disposed on the support, thereafter, at least partially immersing the mold in a bath, and transmitting force between the mold, retainer member, and anchor to retain the mold against movement relative to the support during performance of said step of immersing the mold in a bath.
