The invention discloses a die-casting forming device for an experimental welding steel wire rod and a using method thereof.The die-casting forming device comprises a base, the top of the base is fixedly connected with a transmission box, the exterior of the transmission box is fixedly connected with a motor, the interior of the transmission box is rotationally connected with a cam, and the cam is fixedly connected with the output end of the motor; a swing rod is rotationally connected to the position, located on one side of the cam, in the transmission box, a first sliding groove is formed in the middle of the swing rod, and a first sliding rod is slidably connected into the first sliding groove. The device has the beneficial effects that die-cast steel wire rod forming parts can be automatically taken, manual taking is not needed, the situation that workers are scalded is avoided, meanwhile, the labor intensity of the workers is reduced, the working efficiency is improved, the stability of a second lifting plate in the device during lifting can be enhanced, and the working efficiency is improved. And the height of the electromagnet for sucking the steel wire rod forming part can be adjusted, so that the adaptability is improved.
