Aluminum material stamping die

The utility model relates to the technical field of stamping dies, and discloses an aluminum stamping die which comprises a workbench, the top end of the workbench is fixedly connected with a bearing frame, and the bottom of the bearing frame is fixedly connected with a hydraulic rod. According to the connecting device, the lower die is placed on the placing table, the telescopic rod is controlled to be matched with the clamping block to clamp and position the lower die, the micro threaded rod is rotated, the connecting plate extrudes the fixing plate, secondary fixing is carried out, and the problems that under long-time punching of a press machine, the connecting device can deform, and later-period disassembly is not facilitated are solved; the metal rod is pulled upwards, the tail end of the metal rod and the impact block move downwards, meanwhile, the metal rod is loosened, the metal rod rebounds rapidly through the elastic force of the spring, the impact block impacts the isolation plate, and the problem
