The present utility model discloses a raw material supply mechanism for a three-station injection blow molding machine, comprising a feeding base, an electric heating element, a feeding auger, a raw material tank and a stirring rod. A heating chamber is formed on the inner wall of the feeding base, the feeding auger is mounted on a horizontal shaft, the raw material tank is mounted on the feeding base and connected with the feeding base through an elastic discharging pipe, a vertically distributed rotating shaft is rotatably connected inside the raw material tank, the stirring rod is mounted on the rotating shaft, air holes are formed on the surface of the rotating shaft and communicated with a channel inside the rotating shaft, and a vertical shaft is rotatably mounted on the top of the raw material tank. The raw material supply mechanism for a three-station injection blow molding machine can realize material conveying, anti-blocking discharging and automatic hot gas conveying by using the power of a single motor, solves the problems of material blocking and incomplete melting in existing mechanisms, has a more reasonable structural design, and improves the later molding quality of products.
