Abstract
A composite mold construction for casting on the connector straps, posts, and terminals for lead acid electrical storage batteries according to the techniques of U.S. Pat. Nos. 3,718,174 and 3,802,488 wherein the mold cavity areas are alternately heated by direct flame on one face and then chilled by a coolant on their opposite face to freeze metal in the cavities without freezing molten metal flowing in adjacent flow channels. A plurality of mold cavity partition inserts are arranged to be interchangeable in the main mold assembly to enable a single mold assembly to be utilized for several arrangements of battery cells, strappings, and terminals. Thermal distortion of the mating parts is minimized to maintain the cavities free of leaks by interfitting under cuts and pinned or otherwise keyed couplings between the relatively thin inserts and the more massive primary portions of the mold assembly.
