Abstract
An injection molding nozzle for use with a flowable molding material in a mold die having an elongated member with a fluid passage extending through it and a cap member having an exit orifice in fluid communication with the fluid passage of the elongated member. A torpedo member is located partially in the fluid passage of the elongated member and the torpedo member has a projection that extends into the exit orifice in the cap member to provide heat to the adjacent flowing molding material when the molding nozzle is in use. The heat provided by this projection on the torpedo member prevents the flowing molding material in the nozzle exit from solidifying and interrupting the molding process.
Claims8
An injection molding nozzle for use with a flowable molding material in a mold die comprising an elongated member having an input and an output end portion and a material passage therethrough from the input to the output end portion, a cap having a passage therethrough with an exit orifice removably mounted on the output end portion of said elongated member, a heater surrounding at least a portion of said elongated member and a removable torpedo member located within said cap, said removable torpedo member having a substantially cylindrical projection, said substantially cylindrical projection extending into the exit orifice in said cap whereby the junction of the molding material between the exit orifice and a part being molded has an annular shaped hollow cross section.
