This invention discloses a one-step bottle body injection blow molding machine, including a frame, an injection molding mechanism, a blow molding mechanism, a discharge mechanism, and a turret mechanism. The frame includes a worktable. The turret mechanism includes a turret, a drive structure, and a positioning structure. A set of mandrels is mounted on three sides of the turret. The drive structure includes an outer shaft, an inner shaft, a disc, and a pusher. The inner shaft engages with and is slidably connected to the outer shaft. The turret is fixed to the upper end of the outer shaft. The inner shaft is driven to rotate by a first motor, and the inner shaft drives the outer shaft to rotate. The disc is fixed to the lower part of the outer shaft, located within the pusher's cavity, with its front and rear sides exposed outside the pusher. The pusher moves up and down driven by a first lead screw and a second motor. Three lugs are evenly distributed around the circumference of the disc. The positioning structure includes a positioning element with a limiting groove corresponding to one of the lugs. After moving upwards, the lug rotates and abuts into the limiting groove. This invention achieves the turret's…120It features precise rotation, low manufacturing cost, low maintenance cost, and long service life.
