The invention relates to the technical field of extruding dies, in particular to a plastic extruding die with the anti-scalding function. The plastic extruding die comprises a feeding plate, a splitting plate and a forming plate. A transition plate is installed at the rear end of the forming plate. A cooling plate is installed at the rear end of the transition plate. A feeding cavity is formed in the feeding plate. A die core is installed inside the splitting plate. A cone-frustum-shaped extruding cavity is formed in the forming plate. A heat insulation cover is arranged between the transition plate and the cooling plate. Forming channels are formed between the transition plate, the heat insulation cover and the cooling plate. The tail portion of the die core stretches into the cooling plate. Two water-cooling channels are formed in the cooling plate and located in the two sides of the forming channels in parallel. One ends of the two water-cooling channels are both provided with pipe connectors, and a plasti
