The utility model discloses a hollow blow molding machine with convenient demolding, and relates to the technical field of hollow blow molding machines. The hollow blow molding machine with convenient demolding comprises a machine base, a sliding support is arranged at the bottom inside the machine base, and two second sliding grooves distributed left and right are formed at the front end of the upper surface of the sliding support. The serpentine cooling channels enable the coolant to quickly cool the molten plastic in the upper mold and the lower mold when flowing along the cooling channels, and fully cool the molten plastic, preventing adhesion of insufficiently cooled plastic to the inner wall of the lower mold. One end of the first push rod embedded in the notch drives the top plate to move forward, and the top plate can extrude the molded plastic out of the lower mold when moving forward, realizing convenient demolding and preventing the plastic from being stuck in the lower mold during demolding. At the same time, the spring can play a good buffering role, preventing the first push rod from pushing the top plate forward to damage the plastic surface and affect the molding quality of the plastic.
