ABSTRACT:
A pre-soak station, a washing station, and a drying station are arranged in an in-line manner so that a multiplicity or group of mold support units or workpiece holders arranged single file may be moved sequentially from station to station. A first group of such units after being submersed in a hot water/detergent bath at the pre-soak station is placed on an open rail support or trackway for conveyance to the washing station where nozzles supported on corresponding manifolds surrounding the trackway direct pressurized streams of hot water against the individual units for a predetermined interval or washing cycle. The group of washed units are then conveyed along the same trackway to a tray supported within the interior of a drying chamber having movable baffle means for directing forced, heated air through the interior of each mold or mold support unit during the initial portion of the drying cycle, and for directing the forced, heated air against the top and exterior side portions of each unit during a second or later portion of the drying cycle upon selective movement of the baffle means from a first position to a second position. A plenum defining a surface for supporting the mold support units in their tray in the drying station is connected to a vacuum pump to facilitate rapid and effective drying during both phases of the drying cycle. A hinged door in the assembly comprising the baffle means facilitates removal of the tray housing the dried units so that a subsequent tray may be inserted into the drying station for receiving the next group of units to be dried.
