The invention discloses an electromechanical integrated die capable of adjusting temperature, and particularly relates to the technical field of casting processing. The electromechanical integrated die comprises a lower die body and an upper die body, the upper die body is arranged over the lower die body, a working base table is arranged at the bottom of the lower die body, and a heating tank is arranged at the top of the lower die body. The lower die body is buckled with the upper die body, a lower die shell and the upper die body are fixed by a connecting sleeve, an electric heater is electrified to enable a heat conduction wire to heat a heat accumulator, when a workpiece is subjected to injection molding, plastic is continuously melted, old skin on the surface of the workpiece is reduced, the surface of the workpiece is uniform, redundant gas is exhausted from an exhaust hole, the injection molding density is guaranteed, the quality of the workpiece is improved, a second water chamber and a heat insulation layer effectively insulate heat, potential safety hazards are avoided, after injection molding is completed, the upper die body is lifted up, the lower die shell carrying the injection molded workpiece is separated from the lower die body to be away from a heat source, meanwhile, a miniature water pump works to draw cold water to enter the first water chamber and heat exchange fins for heat exchange, the workpiece is cooled, and the machining efficiency of the workpiece is improved.
