In the prior art, the liquid-cooled parts of new energy charging piles are liquid-cooled parts formed by die-casting, that is, liquid-cooled castings. Since liquid-cooled castings need to be installed with both charging electronic devices and liquid-cooled circulation devices, the shape requirements of liquid-cooled castings are relatively precise. Therefore, liquid-cooled castings need to be calibrated after die-casting.

[0003] In the prior art, liquid-cooled castings are shaped using cold shaping molds. The structure of the cold shaping mold includes a lower mold mounting plate, a lower mold plate, a lower mold shaping block, an upper mold mounting plate, an upper mold plate and an upper mold shaping plate.

The upper mold shaping plate and the lower mold shaping block are opposite to each other and cooperate with each other. When calibrating the liquid-cooled casting, first, install the lower mold mounting plate on the static pad of the hydraulic press, and install the upper mold shaping plate on the dynamic pressure plate of the hydraulic press; then, control the hydraulic press to drive the dynamic pressure plate to lift up, and then drive the upper mold mounting plate, the upper mold plate and the upper mold shaping plate to lift up and open; then, place the liquid-cooled casting on the lower mold shaping block; then, control the hydraulic press to drive the dynamic pressure plate to press down, and then drive the upper mold mounting plate, the upper mold plate and the upper mold shaping plate to press down, and the upper mold shaping plate and the lower mold shaping block cooperate with each other to calibrate the liquid-cooled casting. However, the technical problems of this cold shaping mold and shaping method are: the shaping quality is not high, the stress of the liquid-cooled casting is difficult to release, the product flatness is inconsistent and rebound is easy to occur after shaping, and secondary or repeated shaping is required.
