Abstract: A vacuum-assisted countergravity casting apparatus 10 includes a casting mold 14 disposed on a cheek mold member 28 and supported within a vacuum box 40. The mold 14 includes bottom feed gates 24 communicating with a cavity 22 within the mold 14. The cheek mold member 28 has distribution channels 30 formed in its upper surface 32 and includes a bottom ingate passage 34. A feed stalk 42 is connected to the ingate passage 34 for immersion into an underlying supply of molten metal 12. Actuation of vacuum pump 52 produces a vacuum within the vacuum chamber 46 and draws the molten metal upwardly to fill the cavity 22. Once filled, the mold 14 is pushed sideways on the cheek 28 by ram 68 causing the feed gates 24 to move out of registry with the distribution channels 30. The molten metal is thereby retained in the cavity 22 without assistance from the vacuum.

Abstract: A method for metallurgically bonding cylinder liners (12, 12') within a cylinder block 14 of an internal combustion engine. The liners (12, 12') are cleaned (16) and their outer surfaces coated (18) with a low melting point cooling material (20) such as molten zinc forming a metallurgical bond therebetween. The coating (20) is allowed to solidify forming an outer oxidized layer (24) on the coating (20). The oxidized layer (24) is subsequently removed to expose an unoxidized outer surface (26) of the coating (20). The coated liners (12, 12') are then disposed within a casting mold and molten aluminum-based cylinder block material (36) is poured into the mold and about the coated liners (12, 12'). The molten cylinder block material (36) remelts the coating (20) on the liners (12, 12') and causes the coating to further alloy with the cylinder block material (36), whereupon cooling the cylinder liners (12, 12') are metallurgically bonded to the cylinder block (14).

Abstract: A mold within which molten metal is sand cast, is provided with strategically located chill plates which shape and rapidly cool the molten metal at predetermined locations for hardening those locations relative to the hardness of the remainder of the casting. The mold is formed of a cope and drag frame type flask within which sand is compacted to form the sand cavity. Plates are arranged transversely of the casting cavity and are secured to portions of the flask frame for dissipating heat through the plates and out through the frame. The plates are fixed to portions of the flask and are arranged in opposing pairs which are aligned, coplanar, in abutting relationship. Each plate of each pair is provided with a notch, aligned with its opposite plate, for encircling the portion of the casting to be chill hardened. The pattern used for forming the cavity extends through the aligned notches and between the plates to form the composite sand and metal plate casting surface in the cavity.

Abstract: Apparatus for the vacuum-assisted, countergravity casting of thin-walled metal parts includes a plurality of expendable casting molds supported on a top side of a reusable drag slab. Each casting mold includes a mold cavity and a mold ingate passage extending from the mold cavity into registry with a respective underlying slab ingate passage that extends between the top side and a bottom side of the drag slab and that optionally includes a molten metal filter therein. When the bottom side of the drag slab is immersed in an underlying molten metal pool with the mold cavities evacuated, the molten metal is drawn upwardly through each slab ingate passage and the molten metal filter therein and then through each mold ingate passage registered therewith into each mold cavity. The molten metal filter in each slab ingate passage removes inclusion-forming impurities from the molten metal as it is drawn upwardly into each mold cavity. The presence of objectionable, non-metallic inclusions that can adversely affect part performance is thereby minimized in the thin-walled parts cast in the molds. The drag slab can be reused in the casting of successive sets of expendable casting molds.
