    摘要： The invention relates to a plastic metering system in a device for producing plastic articles, comprising a metering unit (1) forming a block (2) comprising a material feed duct (10), a metering cavity (4) which may communicate with the said material feed duct (10), a material outlet orifice (5) placed on a wall of the said metering cavity (4), and a valve (3) in the form of a cylindrical rod designed to slide through and close off the said material outlet orifice (5), characterized in that the metering unit (1) furthermore includes a piston (7) mounted so as to slide coaxially around the valve (3) so as to allow the volume of the metering cavity (4) to be varied and the material feed duct (10) to be momentarily closed off. The invention also relates to a method for using the said system.

    摘要： 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.

    摘要： Apparatus for injection molding plastic parts. The method includes the step of melting and pressurizing plastic material, directing the molten pressurized plastic material into passages leading to a mold, a selectively opening shut-off valve disposed along the passages, selectively closing the shut-off valve after a predetermined amount of molten pressurized plastic material has entered the mold and cooling the predetermined amount of molten pressurized plastic material in the mold to form a part. The apparatus includes an extruder providing pressurized molten plastic material, a mold adjacent the extruder, passages interconnecting the extruder with the mold, and a selectively operable shut-off valve disposed along the passage.
