Abstract
The application relates to a threaded product injection mold with a directional point and a demolding process, which comprises a lower mold assembly, an upper mold assembly and a positioning assembly. The lower mold assembly comprises a bottom plate, a lower mold base and a guide shaft, one end of the guide shaft is installed on the lower mold base, and the other end penetrates through the upper mold assembly. The upper mold assembly comprises a sliding plate, a fixed plate, a lower mold core, an upper mold core and a rotating shaft, the sliding plate and the fixed plate are both slidably arranged on the guide shaft, one end of the sliding plate abuts against the fixed plate, and the other end abuts against the lower mold base. The lower mold core is installed on the sliding plate, the upper mold core is slidably arranged on the fixed plate and the lower mold core, and a threaded strip is arranged on the outer side of one end of the rotating shaft close to the upper mold core to form the thread of the threaded product. The positioning assembly comprises a cam and an expansion piece, the cam is installed on the rotating shaft, the cam is rotationally connected to the lower mold base, one end of the expansion piece is slidably arranged on the lower mold base, and the other end is clamped to the directional point of the cam. The directional point of the product and the datum of the assembled mold are conveniently unified through the clamping of one end of the expansion piece to the directional point of the cam.
