  • Patent number: 5700499
    Abstract: A valve member locating insert to be mounted in the front end of an injection molding nozzle. The locating insert has an outer mounting collar portion and a concentric inner collar portion which receives the reciprocating valve member to accurately locate it to prevent damage around the gate. The inner collar portion is connected to the outer collar portion by a single connecting vane portion. Melt flows through the locating insert in a C-shaped space between the collar portions. The vane portion and the inner collar portion have upstream and downstream ends which extend diagonally to be washed by the melt flow to avoid deadspots and reduce turbulence.
