Abstract

A mold handling system and method wherein cars are moved along a closed vertical loop. A first elevator positions an empty car adjacent a mold-supply conveyor, whereupon a mold is pushed onto the car, after which the car is transferred into a pre-pour mold storage. The mold-bearing car is then moved onto a second elevator which lifts the car upwardly adjacent an elevated pouring deck. As the mold is elevated, a jacket and weight are automatically deposited thereon, and the mold is poured while the car rests on the second elevator. The mold-bearing car is then moved forwardly through a jacket-and-weight transfer station, after which the jacket and weight are automatically removed and recycled back for positioning on another mold arriving on the second elevator. The mold-bearing car is moved through a cooling region, and this is then transferred onto a third elevator which is tiltable so that the mold is dumped from the car. The third elevator is lowered and the supply car is transferred onto a lowermost return guide rail which transfers the empty cars back to the first elevator. The return guide rail and a portion of the pre-pour mold storage extend in parallel relationship beneath the elevated pouring deck.
