The utility model relates to a die head structure and a medicine bottle blow molding mechanism applying the die head, comprising an air needle body with a hollow interior and tightly fitting an opening of a preform. A free end of the air needle body has a conical part capable of extending into the preform. A gas medium is introduced into the preform through the air needle body to shape the preform in a matching mold cavity. During molding, the opening is in close contact with the air needle body to form the bottle mouth. The utility model solves the technical problem that in integrated extrusion-blow molding, thread forming of the bottle mouth in the mold produces weld lines, resulting in an uneven inner wall of the bottle mouth and cracking of the bottle mouth when twisted by external force for capping and sealing in later use.
