Abstract:

A method and apparatus for dividing the output flow of molten plastic from a conventional molding machine into a plurality of independent molten plastic flows to permit a plurality of plastic articles to be molded simultaneously from a single molding machine. The apparatus comprises a molding tool having a distributor member which divides the flow of molten plastic from an output port of a molding machine evenly into a pair of fluid flow bores. A pair of conventional flow nozzles are incorporated which receive the independent flow streams of molten plastic and independently charge a pair of molding cavities of a molding die generally simultaneously. The molding tool enables a more than 100% increase in the flow of molten plastic therethrough due to the reduction of back pressure seen by the molding machine and more than doubles the efficiency of the molding machine.
