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.

Abstract: A permanent mold for gravity casting of light alloy cylinder heads comprising a base, a pair of lower platens slidably mounted on the base for movement horizontally toward and away from one another cooperating to define a mold cavity when they are in position adjacent one another, and a tiltable upper platen hinged on each lower platen and movable from a position adjacent and overlying a portion of the platen to a position above the platen. A top core support is adapted to be moved into position on the mold when the lower platens are adjacent one another and the upper platens are pivoted downwardly onto the lower platens. A plurality of inserts are adjustably supported on the top core support and extend downwardly to form corresponding cylinder openings in the casting.

Abstract: Battery plates are assembled into stacks forming positive and negative rows of lugs and the stacks are placed within the cells in a battery case. Molding channels are automatically formed around the positive and negative rows of lugs and molten lead alloy is automatically introduced into the molding channels to cast the straps and intercell connections simultaneously within the battery case.

Abstract: A die casting unit employing plural die members and core members which are used in closed position for die casting shaped articles of unusual configuration and particularly articles which are comprised of two or more subcomponents arranged or joined in interconnected assembly, an example of such shaped article being the slider body and pull chain used on slide fasteners. Movement of at least the die members during the molding cycle is effected by rotation of a ring member carrying structure which cooperates with structure on the die members to slide the die members between their open and closed positions.

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.

Abstract: A continuous casting apparatus mold table supports a plate that in turn supports a mold extending through both. The table has opposite side walls extending above the plate, with each side wall supporting a shaft extending lengthwise of it between it and the plate and carrying lugs that overlap the adjacent marginal portion of the plate to clamp it on the table when the shaft is turned in the right direction and locked against reverse rotation. When the shafts are released, the plate and mold can be lifted past the lugs and removed from the table.

Abstract: A method and apparatus for the direct casting of steel slabs for subsequent processing instead of casting ingots and then reducing them to slabs, blooms or billets. A flat elongated casting cavity is formed by an assembly of mold components to define a slab. Prior to casting, this mold is inclined at an angle of about 3.degree. to the horizontal with the bottom end of the casting cavity higher than the pouring end. The molten metal is poured through a sprue attached to the mold assembly adjacent the pouring end. The sprue provides a reservoir for molten metal at a level above the bottom end of the casting cavity so that the casting cavity is completely filled during pouring. When pouring is completed, the mold assembly is promptly tilted to an upright position with the pouring end and sprue at the top.
