A punching pad 201 is installed at the center of the top of the lower mold 1. A support groove 202 is formed on the bottom surface of the punching pad 201, and a symmetrical storage groove 203 is formed on the top surface of the punching pad 201. Supporting pad boxes 204 are evenly installed inside the storage groove 203. The top surface of the supporting pad box 204 is flush with the top surface of the punching pad 201, and both ends of the supporting pad box 204 are aligned with the two ends of the punching pad 201 to facilitate support of the punched parts. Several supporting electric actuators 205 are evenly installed inside the support groove 202. The support electric actuators 205 are staggered, and the input end of the support electric actuator 205 is electrically connected to the output end of the external power supply to ensure that the support electric actuator 205 works normally. The top end of the extended end of the support electric actuator 205 passes through the bottom surface of the support groove 202 and connects to the bottom surface of the support pad box 204. The top surface of the support pad box 204 is rounded. An inflatable pad block 206 is glued to the bottom inside the support pad box 204. A rubber pad strip 207 is glued to the top surface of the inflatable pad block 206. The sides of adjacent support pad boxes 204 are attached to each other.
