The mold is pushed out of the molding machine onto a self-storing automatic mold conveyor, providing unpoured mold storage and quick mold transport to the pouring line. The length of this conveyor, and corresponding number of mold positions, can be varied to suit individual customer requirements.


At the end of the mold storage conveyor, the molds are pushed off the aluminum bottom board onto a special cast iron pouring pallet. The bottom boards are then returned automatically to the molding machine. One board is returned each time a mold is pushed onto the pouring line. The bottom board return conveyor is elevated to provide unrestricted access to the molding machine, and so the machine can easily be operated from either side.


After the mold is pushed onto the pouring line, the weight and jacket are automatically set. The weight is set first, then the jacket, ensuring that setting the jacket does not cause mold shift.


The molds are then gently indexed forward, one station at a time, to the pouring zone using a unique controlled acceleration / deceleration system for smooth motion from start to stop.


Two pouring modes are standard with this system:


1. Select a pouring position and pour the molds in one spot. Molds are poured at rest as they index on command through the designated pouring position. This mode is used when pouring automatically.


2. Walk forward along the pouring line pouring molds as you go. This system can be provided with a large number of molds or positions available for pouring, based on the customer's requirements.


After pouring, the molds continue to cool under weights and jackets until they reach the end of the pouring line. At the end of the line is a combination lateral transfer pusher device. This unit transfers the pallets and molds with weights and jackets to the return line, where they are then indexed in the opposite direction, one position at a time.


Molds continue to index and cool as required. The weight and jacket is then stripped and transferred onto an optional weight and transfer cleaning device. After cleaning, (or if there is no cleaning device) the weight and jacket is precisely set upon a newly loaded unpoured mold on the pouring line. This completes the mold cooling cycle under weights and jackets. The sequence then repeats itself as additional unpoured molds automatically move onto the pouring line.


The line of pallets with molds indexes again, bringing the mold that has just been stripped to the position opposite the mold transfer plate. The transfer plate then elevates and the mold is pushed off onto a cooling tray on the top level of the mold cooling line.


Each cooling tray can carry up to three molds. By controlling the mold transfer pusher, the first mold is pushed to the far end of the empty cooling tray, then a second mold is pushed onto the center of the cooling tray, and a third mold is pushed onto the near end of the cooling tray. The operator can easily select single, double, or triple row cooling based on a specific casting's cooling requirements.


When a tray is loaded, the line of trays on the top level are indexed forward one position, bringing another empty tray into the loading position. Molds continue to cool without weights and jackets until they reach the end of the line on the upper level.


At the end of this line is a combination lowering and transfer device. This unit lowers the cooling tray from the top to the bottom level, and then indexes the line of trays on the bottom level forward one position at a time in the opposite direction.


The molds continue to cool on the bottom level as they move toward the life transfer device on the other end of the system. This unit lifts the cooling tray from the bottom level to the top level, and the indexes the line of trays on the top level forward one position at a time until they reach the mold discharge station.


At this point, the molds are finally dumped onto a vibrating pan or shake-out conveyor, provided by others. Molds are discharged one at a time, or at the same rate they are loaded onto the secondary cooling system.
