A simplified mold handling system has a linear flowpath with adjustable throughput, variable cooling cycle capability, and minimized equipment and cost. The system has a mold handling conveyor with upper and lower levels on which pouring and cooling of the molds occur. The upper level of the conveyor receives sand molds and conveys the empty molds to a pouring station wherein molten material is deposited therein to form castings. After the castings have been poured, the molds are transferred to the lower level of the pouring conveyor for cooling purposes, and then back to the upper level. The sand molds are then either pushed to another row of the pallet, or are pushed down a ramp to a vibrating conveyor for removal of the sand. Such features allow adjustability in the dwell time required for cooling of the given metal. By using a single conveyor line, with a single set of elevators, and multiple pusher arms powered by a single cylinder, the cost of the system is minimized, the system is simplified, and cooling dwell time is still adjustable.
