The utility model discloses a three-plate mold clamping and locking system for a hollow blow molding machine, belonging to the technical field of hollow blow molding machine equipment. The system comprises a mold moving base, above which an outer template, an inner template and a rear template are respectively arranged in a sliding connection manner. The system is characterized in that an inner motor is provided with a connecting rod through a reducer, the connecting rod is arranged perpendicular to the axis of a guide polished rod, a gear I is fixedly sleeved on the outer side of the connecting rod, and a rack meshed with the gear I is arranged on the shaft surface of the guide polished rod. The gear I is provided with helical teeth matched with the rack. The beneficial effects of the utility model are that: the motor cooperates with a worm and a worm gear to drive the connecting rod to rotate, realizing torque change, thereby driving the inner template to move horizontally and stably, avoiding the participation of hydraulic cylinders, increasing the stroke of the equipment, and flexibly adjusting the moving speed and moving stroke. The locking device ensures the safety and stability of mold clamping. The gear I and the rack are arranged in a helical tooth shape, avoiding tooth skipping and increasing the safety factor of the device.
