This invention belongs to the field of plastic processing technology, specifically relating to injection molding, and more particularly to a turret mechanism for an injection blow molding machine and its working method. It includes: a housing, an opening/closing assembly, and a clamping assembly; the housing is connected to a rotating plate; the opening/closing assembly passes through the housing; the clamping assembly is disposed within the housing and is slidably connected to the housing; the opening/closing assembly is adapted to open or close the opening on the end face of the housing, and when the opening/closing assembly opens the opening, it drives the clamping assembly to move away from the housing axis, so that the clamping assembly extends out of the housing and inserts into the rotating plate; this strengthens the connection between the mandrel and the rotating plate during the injection process, preventing mandrel vibration from affecting the injection accuracy and thus avoiding impact on product quality.
