The present utility model relates to a die for a hollow blow molding machine, comprising an annular outer die and an inner die used in cooperation with the outer die. A gap for molten plastic to pass through is formed between the outer die and the inner die. Mutually matching grooves or protrusions are respectively arranged on the inner wall of the outer die and the outer wall of the inner die. The parison extruded by using the die for a hollow blow molding machine is a cylindrical sheet, which can effectively avoid mold accessories and produce more complex products.
