The utility model discloses a double-layer storage-type hollow molding mold with annular groove feeding, belonging to the technical field of hollow blow molding machine equipment. It comprises a thickness adjusting mold body, an injection adjusting mold body, an injection storage mold body and a molding die orifice, and is characterized in that a feeding body is set in a hollow cylindrical shape, two annular flow channels are formed on the outer wall of the feeding body, the upper end of each annular flow channel is connected with a feed hole, the feed holes are arranged perpendicular to the axial direction of the feeding cylinder, the feed hole of one annular flow channel is connected with the feed inlet of the inner core rod through a flow channel, and the feed hole of the other annular flow channel is connected with the feed inlet of the outer core rod through a flow channel. The beneficial effects of the utility model are: the annular flow channels communicated with the feed inlet of the outer core rod and the feed inlet of the inner core rod are formed on the outer wall of the feeding body, realizing uninterrupted feeding and meeting the first-in first-out principle. The annular flow channels allow material backflow, and materials can flow into the feed holes through the annular flow channels in a timely manner without any dead corners, thus preventing material scorching.
