TYPE SL- I
SINGLE LEVEL POURING LOOP
The mold is pushed out of the molding machine onto a self-storing automatic accumulating mold conveyor, providing unpoured mold storage and quick mold transport to the pouring line. The length of this pouring line 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:
- 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.
- 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. This completes the mold cooling cycle under weights and jackets.
The mold indexes one final position to a mold dump conveyor.
The empty pallet continues to the lateral transfer pusher device and indexes across to the loading position on the pouring line where a new mold is loaded. The cycle then restarts.
