The present invention is an improved injection molding nozzle. The
improved nozzle includes a nozzle body having a central melt channel and
a terminal end. A distributor block is formed on the terminal end of the
nozzle body, the distributor block having a nozzle melt channel and a
series of distributor melt channels radiating from the nozzle melt
channel. The nozzle melt channel is coupled to the central melt channel
and each distributor melt channel terminates in a melt well. The improved
nozzle further includes a nozzle ring which is formed on the end of the
terminal end of the nozzle. The nozzle ring surrounds the distributor
block and has a plurality of gate feeders, each of said gate feeders
being in communication with a melt well. The distributor melt channels
radiate symmetrically from the nozzle melt channel to feed the melt
wells. The distributor block is made of a highly thermally conductive
alloy such as BeCu and a heating mantle is provided on the nozzle body
for keeping the nozzle at a suitable melt temperature.
