This utility model discloses a PET bottle production device, which comprises a three-station injection blow molding machine. The three-station injection blow molding machine includes a machine base and a rotary worktable arranged on the machine base, with the worktable provided with three mandrel sets arranged in an equilateral triangle at 120 degrees. A preform injection station, a blow molding station and a demolding station are separately arranged beside the worktable, distributed in a triangle and matched with the mandrel sets arranged in an equilateral triangle. Both the preform injection station and the blow molding station include a fixed lower mold assembly and an upper mold assembly driven by a hydraulic press to lift and lower for matching with the lower mold assembly, and further include a lever mechanism. Guide columns slidably connected with the upper mold assembly are arranged on the machine base in the vertical direction. The clamping force generated by the hydraulic press pushing the upper mold assembly to match with the lower mold assembly via the lever mechanism is not less than 5 times the thrust of the hydraulic press. The utility model provides a PET bottle production device that generates qualified clamping force through the lever principle when the thrust of the hydraulic press is insufficient, ensuring that the produced bottles have no mold clamping lines.
