<p>A valve gated injection molding system having a heated nozzle (14) which is secured to a heated manifold (18) received in a well (24) in a cooled cavity plate (26). An insulative air space (28) extends around between the heated nozzle (14) and the cooled cavity plate (26). An locating flange (20) extends outwardly across the insulative air space (28) from either the nozzle (14) or the manifold (18) into contact with the surrounding cavity plate (26). The locating flange (20) has number of holes (30) extending transversely therethrough according to a predetermined configuration to reduce heat loss from the heated nozzle (14) and manifold (18) to the surroundinig cooled cavity plate (26).</p> |
