A foundry mold jacket to be positioned around a sand mold during pouring of the molten metal. The jacket has a generally rectangular body portion having a central opening to receive the sand mold. The jacket has a depth of approximately six inches and straddles the parting line of the mold. Extensions or lugs extend outwardly from opposite sides of the body portion and locating members are disposed on the upper surfaces of the extensions for positioning a weight on the upper surface of the jacket body. In addition, the extensions are provided with locating holes which receive locating pins on lifting arms that raise and lower the mold jacket relative to the sand mold.
