HLH TYPE IV System

HLH TYPE IV System

Single row pouring plus triple row cooling line

Cooling times in excess of 1 hour

With the Type IV molds can pass through the system a second, third or fourth time without weights and jackets for additional cooling before they are discharged.

The mold is pushed out of the molding machine onto a self storing automatic mold conveyor. This conveyor provides unpoured mold storage and quickly transports molds on demand to the pouring line.

The mold is then pushed off the aluminum bottom board onto a graphite lined cast iron pouring pallet. Bottom board is returned automatically to the molding machine.

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

Molds are gently indexed forward to the pouring zone. Molds can be automatically indexed to the pourer for single station pouring or the pourer can move up the line to pour at multiple positions.

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 a combination lowering and transfer device lowers the pallet and mold (with the weight and jacket in place) from the top to the bottom level. It then pushes the line of pallets on the bottom level forward one position in the opposite direction.

The molds continue to cool on the bottom level as they move toward the lift transfer device on the other end of the system. This unit lifts the pallet from the bottom to the top level, and then pushes the line of pallets on the top level forward one position in the opposite direction.

The weight and jacket are then stripped and the cooled mold is pushed laterally onto the mold cooling line. The weight and jacket are then set down on the empty pouring pallet and the pallet is indexed forward one position to the mold loading station. The weight and jacket are picked up and the sequence repeats as a new unpoured mold is pushed onto the pouring pallet and the weight and jacket are precisely set on the incoming mold.

Each cooling tray can carry up to three molds. A first mold is pushed to the far end of the empty cooling tray, then a second mold is pushed to the middle of the cooling tray, and the third is pushed to the near end of the tray.

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

At the end of the line is a combination lowering and transfer device. This unit lowers the cooling tray from the top to the bottom level, and then pushes the line of trays on the bottom level forward one position in the opposite direction. The molds continue to cool on the bottom level as they move toward the lift transfer transfer device on the other end of the system.

The unit lifts the cooling tray from the bottom to the top level, and then pushes the line of trays on the top level forward one position to the mold discharge station, where the molds are dumped onto a vibrating pan or shakeout conveyor.

Molds are discharged one at a time, or at the same rate they are loaded onto the cooling system.

The operator can select single, double or triple row cooling based on a particular casting's cooling requirements.
