Abstract
There is disclosed a mold assembly for casting posts and plate connector straps onto stacks of plates of lead acid type batteries wherein molten metal is circulated through one or more channels in the assembly and selectively damned to overflow into adjacent mold cavities. Cycle time and properties of the posts and connector straps are improved by constructions which impart a large thermal mass to the channel walls and a small thermal mass to the mold cavity walls. Thermal isolation of the mold cavity walls from the channel walls further enhances these conditions whereby the molds can be elevated in temperature prior to the casting operation and rapidly cooled during that operation. Cooling of the post mold cavities earlier and at a faster rate than the strap mold cavities increases post strength. A mold frame construction containing the molten metal flow channel and one or more inserts for the frame provide the desirable thermal properties while lending flexibility to the apparatus. Coolant circuits are provided for the inserts with flow paths which influence the sequence and speed of cooling of mold insert portions.
