Abstract
A carousel-like continuous co-injection molding system includes an arrangement of upper and lower inclined feed channels. Each of the feed channels has a valve therein positioned upstream of an inlet to an associated mold cavity. The valve is controllable so that adjustments may be made in real time to achieve or maintain delivery of molten polymeric material to the mold cavity at constant pressure.
Claims5
A system for injecting molding parts in a plurality of mold cavities, comprising:
- a source of flowing first molten polymeric material;
- a source of flowing second molten polymeric material;
- a first nozzle in communication with the source of the flowing first molten polymeric material, the first nozzle being disposed at a first elevation;
- a second nozzle in communication with the source of the flowing second molten polymeric material, the second nozzle being disposed at a second elevation;
- a plurality of upper feed channels in fluid communication with the first nozzle, each of the plurality of upper feed channels being in selective communication with a respective mold cavity at a respective first inlet of a plurality of first inlets;
- a plurality of lower feed channels in fluid communication with the second nozzle, each of the plurality of lower feed channels being in selective communication with a respective mold cavity at a respective second inlet of a plurality of second inlets,
- wherein the respective first inlet is separate from the respective second inlet.
