Abstract

The nozzel, installed under a manifold within a runner of the injection molder, gets heated by heating wires inserted into a groove formed in a circumference so that it can prevent the molten resin from solidifying before the resin gets in the molds. It comprises the manifold(2) installed within the runner(1); an insertion hole(5) formed on the lower part of the runner(1); a passage hole(5) formed within the manifold(2); the other passage hole formed in the nozzel(3); a spiral shaped groove(10) formed in the circumference of the nozzel; the heating wire(4) inserted into the groove(10); a copper pipe(11), installed close to the nozzel, for distributing the heat of the heating wire(4); and a stainless pipe(12) forming a space for insulating the heat.
