The utility model discloses a die head lifting mechanism for a hollow blow molding machine, comprising a fixed mounting seat, a connecting bracket and an air blowing box body. The bottom of the fixed mounting seat is fixedly connected with the connecting bracket, a hydraulic rod is installed on the side of the connecting bracket, and the air blowing box body is installed on the side of the hydraulic rod. It also includes: a connecting seat fixed to the end of the hydraulic rod by bolts, a limit post arranged inside the connecting seat, and a connecting bottom plate fixedly connected to the bottom of the limit post; a connecting pipe arranged on the outer side of the air blowing box body, with the end of the connecting pipe connected to a transfer connector. In the die head lifting mechanism for the hollow blow molding machine, by controlling the rotation of the rotating gear, the rotating gear drives the first rack and the second rack on both sides to move towards each other, so that the first blade and the second blade approach each other to automatically cut the blown product at the bottom of the blow molding head, effectively avoiding tensile deformation of the blown product during movement.
