The utility model relates to the technical field of blow molding, and discloses a high-density polyethylene bottle blow molding machine, comprising an equipment box. A stepping motor is arranged inside the equipment box, and an output end of the stepping motor extends to the top surface of the equipment box and is fixedly connected to a gear. A driving sprocket is fixedly installed on the gear, and the driving sprocket and the gear are distributed vertically correspondingly. The stepping motor in the equipment box drives the gear and the driving sprocket to rotate synchronously. There are two groups of gears and driving sprockets, and the two groups of driving sprockets are connected by a double-sided chain. A transmission table is arranged on the equipment box, and a plurality of loading assemblies are arranged on the transmission table. Driven by the double-sided chain, the loading assemblies rotate automatically through linkage sprockets, carrying preforms or bottles to rotate synchronously. This ensures uniform heating of preforms passing through a heating box and uniform contact with cold air during hollow blow molding, achieving uniform heating and cooling effects.
