The present invention relates to plastic machinery equipment, and specifically discloses a hollow blow molding machine and a die head core rod thereof. In the die head core rod, at least two or more layers of runners are arranged along the longitudinal direction of the die head core rod body. The hollow blow molding machine comprises an extruder, a parison die head, a blowing device, a mold clamping mechanism, a parison thickness control system and a transmission mechanism, wherein the parison die head adopts the above die head core rod. The die head core rod of the hollow blow molding machine of the present invention adopts a multi-layer design, which helps to ensure uniform wall thickness of the discharged parison and avoid fusion lines on the product, thereby improving the pressure resistance, appearance and other properties of the product and better ensuring product quality.
