Abstract
A system for providing a desired quantity of a mold material into a mold. The system includes an accumulation system and a metering and delivery system. The accumulation system is a temporary reservoir which accepts and stores mold material and then provides the mold material to the metering and deliver system under pressure on demand The accumulation system is exemplified by a cylinder and a pneumatically actuated piston within the cylinder which is capable of selectively withdrawing and advancing so as to accept and then supply mold material under pressure. The metering and delivery system is exemplified by a metering cylinder and a pneumatically actuated metering piston within the cylinder that has a stroke length that defines a volume that substantially corresponds to the volume of mold material that is delivered to the mold. Adjustments to the stroke length of the metering piston may be made in order to fine tune the quantity of mold material that is placed into the mold. The system is particularly well suited for metering and delivering a desired quantity of a Binghamian pseudo-plastic fluid, such as an aqueous starch-based composition used to manufacture foamed, starch-bound articles of manufacture.
