This utility model discloses a parison die head replacement device for an extrusion blow molding machine, comprising a rectangular cylinder. A rectangular plate is slidably connected inside the rectangular cylinder, a rotating plate is arranged on the top of the rectangular plate, three support rods are fixed on the top of the rotating plate at equal intervals, an annular sleeve is arranged on the top of the rotating plate, a fixing ring is fixed on the outer side of the top of the annular sleeve, and the tops of the support rods are fixed to the bottom of the fixing ring. A support ring is fixed on the inner wall of the bottom of the annular sleeve. Moving the annular sleeve upward makes the die head embedded inside the annular sleeve, and the edge of the bottom of the die head fits the support ring, so that the support ring supports the die head. After all screws at the bottom of the die head are removed, turn the first hand-tightened bolt to clamp the die head, so that the die head is fixed inside the annular sleeve. The annular sleeve only needs to be moved downward without manually removing the die head, avoiding scalding of workers.
