The invention discloses an injection mold of a staggered spiral line type hollow propelling pipe. The injection mold comprises a mold bottom plate, a pressing plate, a half movable template, a half fixed template, a pouring system, a cooling system and a core pulling structure, wherein the half movable template and the half fixed template are put together, the inside of the movable template and the inside of the fixed template are respectively provided with an insert component, a semi-spiral structure is machined on a mold cavity face formed by each insert component, the two semi-spiral structures are staggered and put together oppositely, a cylindrical mold core with one axial groove in one side is inserted into the middles of the mold cavity faces, the core pulling structure is connected with a hydraulic cylinder, the two sides of the mold are respectively and fixedly provided with a sliding block structure, and oil cylinder fixing blocks used for the hydraulic cylinder are arranged on the sliding block structures. According to the injection mold, the mold cavities can be in two halves and are put together oppositely, the semi-spiral structures are staggered and put together oppositely, a transition plane is formed at the joint portion of the spiral faces, the mold finished product rate is substantially improved, product performance is excellent, the long cylindrical mold core can provide power through the core pulling structure connected with the hydraulic cylinder, the hydraulic cylinder slides in a limited mode, the guide accuracy is high, the injection mold is of a structure with two cavities, and the production rate is high.
