The invention relates to the technical field of rapid molding, solves the problems of insufficient uniform and stable feeding of melt used for rapid molding and poor preparation effect, and provides a rapid molding feeding device which comprises a cylinder body, a piston, a driving mechanism, an electromagnetic valve, a heating element and a metal nozzle; the cylinder body is provided with a melting cavity, the top of the cylinder body is provided with a discharge hole communicated with the melting cavity, and the bottom of the cylinder body is provided with a liquid discharge port communicated with the melting cavity; the piston is in sliding fit with the melting cavity; the driving mechanism is connected with the piston to drive the piston to slide into the cylinder body from the discharge hole or slide out of the cylinder body from the discharge hole; the heating element is arranged at the bottom of the melting cavity and is positioned at the liquid discharge port. The printing material in the melting cavity is melted by the heating element heating cylinder body to form molten liquid, the external air is effectively prevented from entering the melting cavity, the air content in the melting cavity is reduced, the piston moves to enable the molten liquid to be stably discharged from the metal nozzle, and the quality of a formed product is improved. |
