INJECTION MOLDING NOZZLE WITH HELICAL COOLING CONDUIT |
摘要 |
An injection molding nozzle for cold runner molding thermosetting molding material in a heated mold. A bore extends centrally through the nozzle to convey liquid molding material from a cooled distribution manifold to a gate leading to a cavity. An integral cooling fluid conduit has a helical portion extending concentrically around the molding material bore. Cooling fluid circulates from a radial inlet portion to a radial outlet portion of the cooling fluid conduit to cool the liquid molding material flowing through the central bore.
