Disclosed is an injection mold. The injection mold includes a mold set having n molds (n is a natural number of 2) defining a cavity for injection molding a green body, and at least one ejector provided on at least one of the n molds to separate an injection-molded part from the mold set. The ejector is provided with a first heater capable of heating the mold set to a first temperature.

Upper and lower temperature control plates of upper and temperature control plate members are attacked so as to interpose a manifold body of a manifold therebetween. Upper and lower oil flow circuits provided in the respective upper and lower temperature control plates control the temperature of the manifold body heated by a plurality of coil heaters to a temperature suitable for preventing carbonization of a molten resin flowing in a flow-dividing type flow path of the manifold body.

A hot runner injection molding apparatus comprising an injection molding manifold having an inlet melt channel and a plurality of outlet melt channels and a plurality of hot runner nozzles coupled to the outlet melt channels. Each hot runner nozzle includes a nozzle body defining a first nozzle body melt channel having a first axis. A nozzle tip housing is coupled to the nozzle body which includes at least two auxiliary melt channel portions each auxiliary melt channel portion has a second axis which is angled with respect to the first axis. At least two nozzle tips are arranged at the nozzle tip housing and in the area of each nozzle tip a nozzle tip heater is arranged, which is oriented substantially along the first melt channel.
