Abstract: This invention relates to a mold rollover apparatus including a wheel member defining an axis and selectively rotatable about the axis and at least one carrier member carried by the wheel member and adapted to carry at least one mold member having a cast part disposed therein. The at least one carrier member is selectively rotatable at least from a first position, wherein the cast part is generally retained in the at least one mold member, to a second position, wherein the cast part is generally free to fall or drop from the at least one mold member. According to the present invention, the at least one carrier member is selectively rotatable about the axis at least from the first position to the second position independent of the rotation of the wheel member about the axis.

Abstract: An apparatus for producing a plurality of cast products includes a plurality of molds, and a casting apparatus which casts products in the molds. A multi-level pallet carries the molds containing the cast products on at least two vertical levels. A loading apparatus loads the molds onto the multi-level pallet. A conveyor moves the multi-level pallet through a cooling area which is sufficient to cool the cast products for removal from the molds. An unloading apparatus unloads the molds from the multi-level pallet. In a method of producing a plurality of cast products, the products are cast in a plurality of molds. The molds are loaded onto a multi-level pallet which carries the molds on at least two vertical levels. The multi-level pallet is conveyed through a cooling area which is sufficient to cool the cast products for removal from the molds. After cooling, the molds are unloaded from the multi-level pallet.

Abstract: The invention relates to a system and method for the automated spin-casting production of molded articles. The system includes a casting turntable and a processing turntable which are rotatively mounted, immediately adjacent to one another. The casting turntable has several spin modules mounted thereon for rotatively supporting mold assemblies. Casting preparation and pouring mechanisms are mounted around the periphery of the casting turntable. The turntable indexes the mold assemblies and positions the assemblies for preparation, pouring and solidification of the cast products. The processing turntable receives the mold assemblies and solidified castings from the casting turntable. Multiple processing stations are mounted around the periphery of the processing table for the removal of the castings from the mold assemblies and preparation of the mold assemblies for additional casting operations. The mold assemblies are returned to the casting table from the processing table for additional casting processes.

Abstract: A bottom pour casting apparatus (100) includes a vessel (114) having a bottom nozzle (118). A stopper rod (112) is coupled to a programmable controller (250) by linkage mechanism (250) for controlling the movement of the stopper rod (112) according to a pouring schedule. An LDT position sensor (216) is coupled to the stopper rod (112) by a cable (238) and also electronically to the controller (250) for sensing the actual position of the stopper rod during a pouring cycle and conveying this information directly to the controller (250) thereby bypassing any backlash present in the linkage mechanism (116) to enable precise control of the stopper rod movement. A method includes rezeroing the position sensor (116) at the beginning of each pouring cycle to account for slag build-up on the nozzle (118).
