The invention relates to the technical field of molds and particularly discloses a relay coil skeleton injection mold. The relay coil skeleton injection mold comprises a first template, a second template detachably connected to the first template, and third and fourth templates sliding between the first template and the second template. The third and fourth templates can slide toward each other oraway from each other. The first, second, third and fourth templates form a mold cavity. The third and fourth templates are respectively connected to first and second mold sheets extending into the mold cavity. The first or second template is provided with two architrave needles extending into the mold cavity. The two architrave needles respectively press against the first and second mold sheets.Through one-step injection molding, the coil skeleton is prepared without an injection molding coil skeleton and the coil skeleton is drilled through a tool so that the manufacturing efficiency of thecoil skeleton is improved
