METHODS AND SYSTEMS FOR METERING AND DELIVERING A MOLDABLE COMPOSITION INTO A MOLD

摘要

A system and method for providing a desired quantity of a mold material (76) into a mold. The system includes an accumulation system and a metering and delivery system. The accumulation system (62) is a temporary reservoir which accepts and stores the 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 (64) and a pneumatically actuated piston (66) 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 (102) and a pneumatically actuated metering piston (104) 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.
