Claims20
An injection molding apparatus comprising:
- a gate component defining at least a portion of a mold cavity, the gate component having a draw axis and a recess extending into the gate component towards the draw axis, the recess including an alignment bore and terminating at a mold gate leading to the mold cavity, the mold gate having a gate axis intersecting the draw axis at an acute angle;
- a nozzle laterally offset to a side of the gate component, the nozzle having a melt channel for receiving a molding material from a source, the melt channel including lateral channel portion extending towards an outward facing sidewall of the nozzle and terminating at a nozzle outlet;
- and
- a nozzle tip coupled to the nozzle at an acute angle to the draw axis, the nozzle tip received in the recess in the gate component, the nozzle tip including
- an inner tip component defining at least in part a tip channel in fluid communication with the nozzle outlet and the mold cavity and an outer tip component surrounding the inner tip component and having an outer alignment surface mating with the alignment bore of the recess, and the inner tip component having an upstream end abutting the nozzle, a downstream end, a conical portion having an apex at the downstream end, and the conical portion having a cone axis that is misaligned with the gate axis.
