Auxiliary feeding device for injection molding machine

The utility model relates to an auxiliary feeding device for an injection molding machine. The auxiliary feeding device comprises a feed pipe and a worm penetrating through the feed pipe, wherein the front end of the feed pipe is connected with a material pipe of the injection molding machine; a storing barrel is arranged above the feed pipe; a feed pipe system is connected with the lower part of the storing barrel at an angle; the feed pipe is communicated with the material pipe and the storing barrel; a worm system is coaxially arranged inside the feed pipe; the front end of the worm extends to the front end of the feed pipe, and a rear end system of the worm is connected with a driving device; the driving device drives the worm to rotate in the feed pipe intermittently. The auxiliary feeding device enables the feed pipe to be fully filled with plastic materials uniformly and enables the plastic materials to flow into the material pipe, so that the precision of the injected product is improved, and the qual
