The invention provides a metal die preheating device. A first split-flow branch pipe and a second split-flow branch pipe are respectively arranged at two ends of a heating main pipe, and an initial end of the heating main pipe is provided with a tee connector which is respectively provided with a first connector through a first valve and a second connector through a second valve. The metal die preheating technology of the metal die preheating device includes the steps of firstly opening dies at two sides of a metal die, then fixing the metal die preheating device on the metal die so that the first split-flow branch pipe is floated in a shape cavity of the metal die and the second split-flow branch pipe is floated in a pouring gate of the metal die, then connecting a fuel source on the first connector and connecting a pneumatic supply on the second connector, opening valve switches so that fuel gas flows into the two split-flow branch pipes through the heating main pipe to be ignited and burned after flowing o
