The utility model discloses a hot stamping forming die for a double-layer metal surfacing ultrahigh-strength steel plate. Wherein a conformal cooling water channel (d) is arranged on the die base body(c), a transition layer (b) is formed on the die base body (c) along a copper alloy material with high build-up welding conduction efficiency and better strength and toughness, and a strengthening layer (a) is formed on the transition layer (b) by build-up welding of a high-temperature alloy low-hydrogen build-up welding wire with high strength and hardness and better toughness. The utility modelprovides a hot stamping forming die which can greatly improve the wear resistance, the deformation resistance and the like of a working area of the hot stamping forming die, prolong the service lifeof the die, reduce the manufacturing cost of the die and improve the production efficiency of hot stamping. Low-cost, low-energy-consumption, short-time, high-utilization-rate and high-performance mold manufacturing and using are achieved, and the mold has very wide application prospects and scientific research significance.
