PURPOSE: A hot runner system with a valve gate type three-hole hot runner for an injection mold is provided to prevent a gate from being blocked by uniformly injecting molten resin in a regular triangular direction. CONSTITUTION: A hot runner system with a valve gate type three-hole hot runner for an injection mold comprises a three-hole hot runner nozzle(4), nozzle tips(9), and a heater(7). The nozzle tips are coupled to the bottom ends of resin injection ports(6a,6b) of the hot runner nozzle. When the nozzle tips are formed using a moldmax material with high hardness and high thermal conductivity, a cylindrical small and thin product is injection molded using fiberglass reinforced plastics, and heat from the heater is uniformly transferred to the ends of the resin injection ports.
