The utility model discloses a lightweight plastic pencil extrusion die, which comprises an inlet seat with a lead core inlet, a rod cone sleeve at the lower end of the inlet seat, a leather cone sleeve at the lower end of the rod cone sleeve and an outlet seat at the lower end of the leather cone sleeve. An outlet core is arranged on the outlet seat, and a lead core cone sleeve is connected on the inlet seat, and a lead core cone sleeve is arranged inside the lead core cone sleeve. The lead core feed chamber is connected with the lead core feed outlet, and the lead core cone sleeve extends into the rod cone sleeve, and a rod gap is formed between the lead core cone sleeve and the rod material cone sleeve. The rod material transition chamber is arranged on the rod material gap, and the rod material inlet connected with the rod material transition chamber is measured outside the rod material cone sleeve. A leather gap is formed between the sleeves, and a leather transition chamber is arranged on the leather gap, and a leather inlet connected with the leather transition chamber is arranged on the leather cone sleeve.
