The present utility model discloses a raw material supply mechanism for an injection blow molding machine, comprising a feed frame. Rear support blocks are fixedly installed on both sides of the bottom of the feed frame, a rotating wheel is fixedly installed at the left end of the rotating rod, and a second transmission belt is movably installed on the outer side of the rotating wheel. A discharge port is formed at the bottom of the right end of the feed frame, a fixed rod is fixedly installed on the inner wall of the storage bin, a moving rod is movably sleeved at the central position of the fixed rod, a baffle matched with the moving rod is fixedly installed at the top end of the moving rod, and a contact plate is fixedly installed at the bottom of the moving rod. A rotating rod is fixedly installed on the inner wall of the storage bin. When the auger rotates, the top outer wall of the auger fits the bottom outer wall of the contact plate at the bottom of the moving rod, forcing the moving rod to move upward, so that the outer edge of the cover plate no longer fits the inner wall of the storage bin, allowing raw materials to flow out from the gap. The rotating speed of the auger makes the cover plate move up and down periodically, thus preventing blockage.
