Abstract: Injection molding apparatus includes: a mold structure having a main axis and a mold cavity; a core in the mold cavity, defining a mold envelope bounded by an inner sidewall, an inner endwall at one end of the inner sidewall, an outer sidewall spaced apart from the inner sidewall, and an outer endwall spaced apart from the inner endwall; a nozzle at an end of the cavity, including an interior channel communicating with the mold envelope; a pin in the nozzle, moveable between a closed position forming a part of the outer endwall and blocking flow between the interior channel and the mold envelope, and an open position permitting fluid flow; and a locking pin within the core and moveable between a retracted position free of the outer endwall, and an extended position received within the outer endwall, preventing relative lateral movement of the core and the mold cavity.
