Multi-parameter, multi-layer co-extrusion blow molding machine includes a plasticizing system, a die extrusion system, and a blow molding system. The die extrusion system includes one or more dies, each die having a feed port connected to a screw. Each die includes a die body connected to an orifice die. The orifice die has a core die, and the core die and orifice die form an extrusion port. The machine is characterized by having a guide fluid A and a guide fluid C installed inside the die body. The guide fluid A has a step, and the smaller end below the step is fitted into the central hole C of the guide fluid C. The mandrel has a guide channel A and a vertical flow channel A. The larger end has a horizontal flow channel A. Guide channel A contains guide channel B. Guide channel B has a guide channel B and a vertical flow channel B. Guide channel B is connected to the feed inlet A. Guide channel C has a horizontal flow channel C. Horizontal flow channel C connects guide channel A and feed inlet B. Guide channel C has a guide channel C and a vertical flow channel C. Guide channel C is connected to feed inlet C. Vertical flow channels A, B, and C converge at the outer wall of the mandrel and connect to the extrusion port.
