This utility model invention discloses a three-station layout structure for a three-station one-step injection blow molding machine that can shorten the time required for a single cycle. It includes: a rotary turntable, on which three mandrel groups are arranged in an equilateral triangle at 120-degree intervals. The three mandrel groups have the same structure, and each mandrel group includes at least one mandrel. The three stations include: an injection molding station, a blow molding station, and a cooling and demolding station, corresponding to the three mandrel groups. The injection molding station is provided with injection cavities corresponding to the mandrels in the mandrel group and injection hot runners connected to the injection cavities. The blow molding station is provided with blow molding cavities corresponding to the mandrels in the mandrel group. The cooling and demolding station is provided with cooling cavities and a demolding mechanism corresponding to the mandrels in the mandrel group. This utility model invention is particularly suitable for the injection blow molding of thick-walled plastic bottles.
