Injection molding apparatus having a removable nozzle seal (110) which screws onto the outside of the front end (76) of a heated nozzle (12). A mounting sleeve (98) having a threaded outer surface (104) is integrally mounted around the front end (76) of the nozzle (12). The nozzle seal (110) has a retaining portion (118) with a threaded inner surface (120) to screw onto the mounting sleeve (98) extending rearwardly from a central nut portion (112). A sealing and alignment flange portion (122) extends forwardly from the central nut portion (112) and fits into a cylindrical portion (124) of a well (14) in the mold (18) to accurately align the front end (76) of the nozzle (12) and prevent melt leakage between the heated nozzle (12) and the surrounding cooled mold (18). In another embodiment, a sealing and alignment portion (136) of the nozzle seal (110) extending forwardly into an opening (148) in the mold (18) forms the gate (90).
