Then, the hot pressing raw material is placed in the lower die core 21 of the lower die base 2, and then the upper die base 1 is moved towards the lower die base 2 and pressed together, so that the upper die core 11, the lower die core 21, and the side die core 31 jointly enclose a final closed die cavity for preparing the power connection terminal. Then, the upper die base 1 and the lower die base 2 are respectively heated, so that the hot pressing raw material can be melted and formed under high temperature and high pressure in the final closed die cavity. Finally, the upper die core 11 moves away from the lower die core 21 to open the die, the side clamping sliders 3 slide away from the center of the lower die base 2 to open the die left and right, and the ejector rod member 4 can penetrate upwards through the bottom of the lower die base 2, so that the power connection terminal formed in the lower die core 21 is jacked up and demolded.
