Casting arrangement for forming plate-shaped metal parts
First Claim
1. Apparatus for casting molten metal into plate-shaped parts, comprising a pair of spaced rolls having their axes arranged horizontally, an endless conveyor trained over said rolls forming an upper and a lower run each arranged approximately horizontally, said conveyor comprising a pair of laterally spaced link chains each comprising a plurality of serially arranged hinged links, an open casting mold plate supported on and extending between each pair of oppositely disposed said links in said chains and said mold plate having a recessed surface therein, each said mold plate having a transversely extending separating edge extending upwardly from the recessed surface in the upper run of said conveyor for separating successively arranged recessed surfaces formed by said mold plates, an approximately horizontal upper guide rail and a lower guide rail spaced below said upper guide rail provided for each of said chains, a hinge pin extending transversely of said conveyor between each pair of oppositely disposed links, a roller mounted on each end of said hinge pin and said rollers arranged to run on said upper and lower guide rails, the transverse ends of adjacent said mold plates being arranged in abutting engagement and the joints formed therebetween, in at least the upper run of said conveyor, being arranged in vertical planes passing through said hinge pins, said separating edge of each said mold plate being spaced from the leading and trailing ends of said mold plate and the recessed surface for the plate-shaped metal part extends between an adjacent pair of said separating edges on adjacent said mold plates with the abutting surfaces of the adjacent said mold plates located intermediate said adjacent pair of separating edges so that as each said mold plate is deflected about said roll at the end of its upper run it effects the separation of the leading end of the plate-shaped metal part while its trailing end remains supported in the following said mold plate, and means positioned at the downstream end of the upper run of said conveyor for lifting the leading ends of the plate-shaped metal parts separated from said mold plate as said mold plates move about said roll at the end of its upper run for removing the trailing end of the plate-shaped metal parts from the recessed surfaces in said mold plates and for moving the metal parts away from the downstream end of said conveyor.

Abstract
In casting molten metal into open recesses in moving molds for forming plate-shaped metal parts, the molds extend between and are supported on individual links of a pair of laterally spaced link chains forming a conveyor having an upper run and a lower run and trained over a pair of spaced rolls. The upper run of the conveyor in which the molten metal is poured and cooled, travels in a rectilinear horizontal path. The links are supported on hinge pins and rollers mounted on the hinge pins ride along guide rails. Each pair of adjacent molds abut at a joint located in a vertical plane which passes through the hinge pin interconnecting the links supporting the mold. Each mold plate has a transversely arranged separating edge defining a spacer between the recesses in adjacent molds. The separating edge can be located at the end of the mold or at a location intermediate its ends. At the downstream end of the upper run, as the conveyor moves around the roll, the plate-shaped metal parts are removed from the recesses in the molds.
