The utility model relates to the field of capacitor manufacturing equipment and more specifically relates to a cold-punching mould for making a rapid charging capacitor, which comprises a body and a fixed base. The body is arranged above the fixed base and is at a certain distance from the fixed base. A working platform is arranged on the fixed base. A positioning part is arranged on the working platform. The body is movably provided with a punch. The punch is arranged corresponding to the positioning part and is capable of moving towards the direction of the positioning part. The bottom of the punch is provided with a recess and a vertically and downwardly extending contact pin is arranged on the recess. By means of the cold-punching mould for making the rapid charging capacitor, the internal resistance of the capacitor can be effectively reduced. Meanwhile, the reliability of the capacitor is ensured.
