Abstract
A composite mold construction for casting on the connector straps, posts, and terminals for lead acid electrical storage batteries 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 junctions between the insert and frame free of leaks by surface geometries which provide broad surfaces of contact drawn together by bolts securing the relatively thin inserts by tapped bores in the more massive primary portions of the mold assembly.
