A high-luminosity polyethylene pipeline production mold and a processing method belong to the technical field of pipeline production molds; the production mold comprises a mouth mold and core mold fittedly disposed in the mouth mold; a primer layer and a finish layer are fittedly disposed on the internal surface of the mouth mold and the external surface of the core mold respectively from the inside to the outside; the primer layer is Dupont 420-703 paint with a spraying thickness of 10-15 microns, and preheating is performed at 190-210 DEG C for 8-12 minutes after spraying; the finish layer is Dupont 857B-210 paint with a spraying thickness of 20-30 microns, and drying is performed at 390-410 DEG C for 10-30 minutes after spraying so as to allow the product surface to become shining black. A mold prepared by the high-luminosity polyethylene pipeline production mold of the invention has a simple structure, and an easy processing method; a polyethylene pipeline prepared by the mold have a smooth surface, a roughness coefficient increased from 0.009 to 0.004, beautiful appearance, and good using performance.
