The present utility model belongs to the technical field of extrusion blow molding machines, and specifically relates to a head lifting mechanism for an extrusion blow molding machine, comprising a frame. An extrusion mechanism is arranged on the upper end surface of the frame, a mounting bracket is arranged at the lower end of the extrusion mechanism, the rear end of the mounting bracket is rotatably connected to the frame, and a lifting mechanism is arranged at the front end of the mounting bracket. The lifting mechanism comprises a lifting motor, a lifting cam is mounted on the output shaft of the lifting motor, and a fixed block for being pushed by the lifting cam is arranged at the front end of the mounting bracket. During operation, the lifting motor drives the cam to rotate, and the end surface of the cam always keeps in contact with the fixed block during rotation, thereby slowly pushing the fixed block in the mounting bracket to lift the head of the extrusion mechanism. The working process is stable, reliable and easy to control.
