MOLD FOR A BATTERY CAST ON STRAP

摘要

A dual temperature mold assembly (100) for maintaining a mold cavity (12,,102) used in a cast on strap process at two different temperatures facilitates the removal of the solidified strap (70, 170) after the molten metal is solidified. The mold assembly (100) includes a mold cavity (12) having walls (121, 132, 142, 144, 162) attached to different mold assembly segments (110, 130, 140, 160) that are heated or cooled by thermal energy input and coolant processes which can maintain the mold cavities (12) at different temperatures, so that molten metal (98) around the battery plate lugs (44, 46) in a mold cavity segment (140) is solidified while the side walls (132, 162) of the mold cavity are exposed to at least one adjacent heated segment (130, 160) to provide thermal energy thereinto, resulting in a reduction of the amount of molten metal (98) necessary for a cast on strap (70, 170), and reducing the amount of thermal energy input into the process for manufacturing the straps (70, 170).
