The utility model provides an automatic pore opening tooling regardless of thickness of the controller casing of the electric vehicle, and discloses a pore opening mold for a controller casing of an electric vehicle, and the pore opening for a battery case can be realized normally while the depth of a special-shaped punch is adjusted. The pore opening mold comprises an upper mold plate and a lower mold plate and is characterized in that the upper mold plate is fixed on the upper surface of the lower mold plate through polyurethane; the lower surface of the upper mold plate is connected with an upper backing plate which is fixed with an upper fixing plate together; guide columns are designed on the upper fixing plate; and a concave mold on the lower mold plate is provided with round holes corresponding to the guide columns. The pore opening mold for the controller casing of the electric vehicle has the advantages that the pore opening tooling is wide in application range and safe, and can perform pore opening on controller casings with different thicknesses and protect safety of a worker.
