Patent number: 5505247Abstract: In order to effectively enhance the overall efficiency in casting operations, a process and system for cooling and cleaning a casting is disclosed. The process and system include removing the casting from a molding machine after it has been formed. The casting is then moved to a punch-out station for removing it from a sand mold. Next, the casting is moved to a shake-out station for shaking residual sand from it. The casting is then conveyed away from the shake-out station on a cooling conveyor. Next, the temperature of the casting is monitored at or near a downstream end of the cooling conveyor. The casting is then transferred from the cooling conveyor into a vibratory cooling drum where it is further cooled. In addition to these unique aspects, the process and system includes controlling the rate of cooling of the casting within the vibratory cooling drum.Type: GrantFiled: May 21, 1993Date of Patent: April 9, 1996Assignee: General Kinematics CorporationInventor: Albert Musschoot

Patent number: 5350160Abstract: An improved method and apparatus for heat treating metal castings with sand cores provides for removal of the sand core and recovery of the sand core material for reuse. The method and apparatus eliminate the need for removing the sand core from the casting prior to heat treatment and thus eliminate the labor, expense, and possible damage to the casting incidental to conventional core removal techniques such as chiseling and shaking. The method involves heating the casting with sand core therein to a temperature sufficient to burn off the binder component of the sand core. The sand comprising the sand core is then blown out of the casting by directing a flow of air over the workpiece. The sand thus dislodged is then collected for reuse. According to the disclosed apparatus, the castings are heated in a furnace having fans for directing a flow of air over the workpieces.Type: GrantFiled: November 9, 1993Date of Patent: September 27, 1994Assignee: Consolidated Engineering CompanyInventors: Paul M. Crafton, Scott P. Crafton

Patent number: 5253698Abstract: Sand castings are removed from their molds before cooling and reheated in a heat treating booster furnace. The castings are transferred from the booster furnace to a rotary drum filled with agitation media. As the castings pass through the media drum, they are simultaneously cleaned of sand particles and down-quenched by the agitation media. The system is particularly suited for austempering cast iron parts.Type: GrantFiled: February 26, 1992Date of Patent: October 19, 1993Assignee: Applied ProcessInventors: John R. Keough, William R. Keough, Bela V. Kovacs

Patent number: 5080161Abstract: A system for preparing a self-hardening casting mold including a mass of sand which contains an organic binder and which has a pattern-contact layer having a surface for contact with a pattern disposed in a flask. The pattern defines a cavity into which a melt is poured to produce a cast product. The mold further includes a mass of ceramic balls placed on the pattern-contact layer of the sand mass. The system includes a temperature adjusting device for regulating the temperature of the mass of ceramic balls prior to introduction thereof into the flask, so as to control the hardening rate of mass of sand in the flask, a separating device operable on a mixture of sand and ceramic balls obtained from the mold after the cast product is produced by the mold with the pattern removed. The separating device separates the ceramic ball from the sand, and supplies the ceramic balls to the temperature adjusting device.Type: GrantFiled: November 6, 1990Date of Patent: January 14, 1992Assignee: Okamoto Co., Ltd.Inventors: Takao Horie, Shoichi Sakai

Patent number: 5054538Abstract: In an automatic foundry plant of the kind in which at an extraction station (41) water is dosed in (at 42) in order to maintain the correct moisture content in the molding sand, which is returned to the molding station (11), and in which new molding sand (at 43), new binder (at 44), and/or new additive (at 45) may be added in a sand treatment station (46), the new feature consists in that the dosing of water and possibly of the other agents mentioned is controlled by means of an automatic control system (51-53) in dependence of information collected upstream of the extraction station regarding the condition of the individual molds arriving at the extraction station, especially with regard to whether metal has been poured in them or not, a very important factor for the moisture content, because this is greatly reduced by the hot metal poured.Type: GrantFiled: May 21, 1990Date of Patent: October 8, 1991Assignee: Dansk Industri Syndikat A/SInventor: Peter Ibsen

Patent number: 4955425Abstract: Apparatus for non-impact handling of foundry castings utilizes a sand pervious basket to receive a sand mold and casting and to segregate the casting from the mold. A turntable assembly lifts and translates the basket to a secondary conveyor which removes the casting for further processing. The secondary conveyor may be a walking beam conveyor adapted to operate inside a quenching tank and the basket adapted to align with the walking beam conveyor for removal of the casting.Type: GrantFiled: September 19, 1988Date of Patent: September 11, 1990Inventor: James F.

Patent number: 4807689Abstract: A rotary take-off system comprising an apparatus for removing manufactured objects such as cast metal anodes from a first work station and transporting these objects to a second work station. The first station, at which the object is manufactured, may preferably be a mold located upon a rotatable casting wheel, while the second work station is preferably a quenching medium for cooling and temporarily holding the manufactured object. After the object is manufactured at the first work station it is then transported through an arc of approximately 180.degree. by a pair of rotatable arms to the second work station for further processing. The arms are coupled to a motor which is operated in order to cause the rotation thereof. Within the quenching medium, a pair of pivotably connected hydraulic push arms is positioned, which accept the anode as it drops from the rotatable arms and which thereafter facilitate the sliding and stacking of the completed anodes to a rear portion of the quenching medium.Type: GrantFiled: February 10, 1987Date of Patent: February 28, 1989Assignee: Magma Copper Co.Inventor: Raymond D.
