Appl. No.:

09/608176

Billy J. Cagle - Indianapolis IN

Edward A. Reelfs - Davenport IA

Assignee:

International Engine Intellectual Property Company, LLC - Warrenville IL

International Classification:

B22C 2500

US Classification:

164 5, 164130, 164137, 164323, 164339, 164394

Abstract:

The use of green sand is eliminated by replacing green sand molds with all core sand assemblies that provide, during casting, both the internal and external surfaces of a casting, such as a cylinder head or engine block. In the process, a mold is formed from the same core sand that is used to form the core elements defining the internal passageways of the casting. A mold-core carrier is constructed with tapered sides that hold the assembled mold and core elements together during pouring of the molten iron alloy into the mold-core assembly and the cooling period to form the casting. Although the carrier sides can use a refractory liner, preferably the sides are made of replaceable sheet metal backed by an open structural framework to enhance cooling of the casting. After the casting is formed, the core sand from both the mold elements and the core elements is recovered, and may recycled and processed to form further mold elements or core elements or both.

International Classification:

B22C 910
B22C 922

US Classification:

164137

Abstract:

A one-piece cylinder head casting, including reliably located passageways for fuel-air intake, for exhaust and for coolant, is formed by a plurality of interengaging one-piece core elements including a one-piece coolant jacket core, a one-piece exhaust core and a one-piece fuel-air intake core, all reliably positioned and held together in an integral core assembly. Preferably, a further core element having a plurality of core supporting and positioning surfaces provides surfaces that mate interfacing surfaces of the one-piece water jacket core, one-piece exhaust core and one-piece intake core and support such cores in position with respect to one another, and the intake core may be provided with a plurality of interfacing surfaces to lock the plurality of core elements into a unitary core assembly. Such cylinder head casting may also be provided with integral walls forming a long, open intake manifold cavity in the side of the cylinder head. Castings, including such cylinder heads, may be provided with long, narrow, open cavities, having lengths many times their widths, formed by uniform walls of casting metal, without foreign elements, through the use of a two-piece, long, narrow core element including an inner core element-supporting portion that is adapted to permit the escape to atmosphere of gas generated during casting.

International Classification:

B28B 728

US Classification:

414761

Abstract:

The present invention permits reliable lifting and inverting of one or more casting core elements and positioning the one or more casting core elements in a mold flask. The invention generally includes an outer frame and an inner frame assembly, which are coupled such that they may move vertically relative to each other. The invention further includes apparatus which engage the casting core and invert the casting core, and further align the casting core to a mold to which the core is transferred. The present invention also allows for simultaneous engaging, inverting and aligning of a plurality of core elements. The present invention allows cores to be inventoried and located for automatic handling in a position that permits visual inspection and reliable handling and placement at high production rates therefor.

Inventors:

Billy J. Cagle - Indianapolis IN

Assignee:

Navistar International Transportation Corp. - Chicago IL

International Classification:

B22C 910
B22C 922

US Classification:

164137

Abstract:

A closed mold for a cylinder head is provided having two widely spaced wall portions, at least one of the widely spaced wall portions being in communication with the atmosphere through an opening in the closed mold. The widely spaced wall portions define the ends of a long open cavity within the mold and provide core supporting portions for a long, narrow core element adapted to form an elongated, narrow open cavity within the casting. A narrow core element is provided between the core supporting portions of the widely spaced wall portions of the mold without intervening support. The long narrow core element comprises an outer portion of casting sand adapted to form the walls of the elongated, narrow open cavity of the casting extending between the core supporting portions. The narrow core element further comprises an inner portion for supporting the long, narrow core element and for providing a gas passage extending to the one wall portion. Molten metal is poured into the closed mold and the long open mold cavity while permitting gas emitted from the casting sand to escape to the atmosphere by carrying the gas to the atmosphere with the inner portion of the long, narrow core element and the opening in the closed mold.
