The invention discloses a plastic container blow molding machine for teaching, comprising a barrel and a feed hopper. An injection nozzle is arranged at one end of the barrel, a check valve is arranged in the barrel, a rotating shaft is rotatably arranged in a transmission cavity, and blades are arranged on the outer circumferential wall of the rotating shaft. A plurality of heating plates are arranged on the outer circumferential wall along the axis of the barrel. A hollow isolation chamber is fixed on the end face of the barrel near the feed hopper, a plurality of air holes are formed on the outer wall of the isolation chamber, a linkage shaft is arranged in the isolation chamber, and a meshing disc is fixed at the other end of the linkage shaft. A chuck is arranged on the extension section of the motor output end. By arranging an isolation chamber on the power output end connected to the rotating shaft for material conveying, heat conduction between the rotating shaft and the motor output end is blocked on the premise of ensuring normal rotation of the rotating shaft, preventing residual heat from the heating plates from being transmitted to the motor output shaft through the rotating shaft and reducing the probability of motor failure.
