A mold clamping mechanism of a plastic extrusion blow molding machine comprises an extrusion mechanism, a cutting mechanism, a mold and a mold opening and closing mechanism on a base. The plastic extrusion mechanism is a screw extrusion device connected with a blank extrusion die head after a motor passes through a reduction device, and a blow pin of a bottle blowing mechanism is arranged on the die head. The cutting mechanism is a cutting moving cylinder driving an electric heating wire on a support. The blow mold and mold opening and closing mechanism are provided with swing arm connecting rods on the back of the front and rear templates, sliders are arranged on the bottom surface of the connecting rods and connected with swing arms, the swing arms are driven by a stretching cylinder, the middle parts of the swing arms are fixed by two bottom plates, linear guide rails are arranged on the top surface of the bottom plates to cooperate with the sliders, and a synchronization mechanism is arranged on the bottom plates, consisting of a left synchronization connecting rod, a synchronization swing arm and a right synchronization connecting rod. The synchronization swing arm is fixed on the bottom plate, one end of the left synchronization connecting rod is fixed on the front template and the other end is fixed on the left end of the synchronization swing arm, and one end of the right synchronization connecting rod is fixed on the rear template and the other end is fixed on the right end of the synchronization swing arm.
