The utility model relates to the technical field of injection molds, in particular to a parison injection mold of an injection blow molding machine, comprising an injection mold body, a sealing mechanism is arranged on the outer wall of the injection mold body, a heat dissipation plate is installed on the outer wall of the injection mold body, and a heat dissipation groove is arranged on the outer wall of the heat dissipation plate; the sealing mechanism comprises a fixed plate fixedly connected to both sides of the center of the injection mold body, a sealing seat is slidably connected to the top of the fixed plate, and a connecting plate is slidably connected to the bottom of the sealing seat inside the fixed plate. By designing the parison injection mold of the injection blow molding machine and using the sealing mechanism in the device to block gaps on the outer wall of the injection mold body, the invention solves the problem that the existing parison injection mold is composed of two closed molds, resulting in small gaps after the two molds are closed, so that plasticizer flows out through the gaps during injection and affects the quality of finished products.
