ABSTRACT:
Method for injecting molten lead from a reservoir into a die mold cavity formed about an aperture in the wall of a plastic battery for casting lead-alloy battery terminal connectors. Batteries are positioned adjacent the molten lead reservoir of the apparatus and mold portions move together to hold the battery containers in a clamp-like action. Molten lead is die cast under pressure into the mold cavity in which a stainless steel threaded nut is positioned. The lead is forced through a heated chamber into a portion of the mold which may be water cooled. The mold is designed to allow venting of gases, thereby eliminating porosity; and the apparatus is designed to provide casting which is free of jagged projections in the sprue hole. The aperture in the battery wall is surrounded by a series of plastic annular rings extending outward from the battery wall but being a part thereof. The molten lead surrounds the annular rings and fills the spaces therebetween when it is injected into the cavity. The heat from the molten lead partially melts the plastic rings thereby forming a good seal between the casting and the battery wall.
