The present invention relates to an injection head of a silicone injection molding machine, wherein the injection head comprises: a head body which is installed at a lower part of a barrel of the injection molding machine and includes a silicone injection flow path inside; an injection hole opening/closing valve installed inside the head body for opening or closing the injection hole of an injection cap; and the injection cap installed at a lower end of the head body for injecting liquid silicone through the injection hole and into a mold. The injection head allows a liquid silicone mixed with a hardening agent to be injected into the mold more stably, and also can inhibit the hardening of the silicone during the silicone injection and secure the closure of the injection hole of the injection cap once the injection of the liquid silicone is completed.;COPYRIGHT KIPO 2016
