Abstract
The invention relates to a composite stamping die. The composite stamping die comprises an upper punch and a lower punch, a material pushing block, a stroke cavity, a reset mechanism, and a thrust mechanism, wherein the outer wall of the upper punch is provided with the material pushing block which is in sliding connection with the upper punch in a sleeved mode, the stroke cavity which can enable the material pushing block to slide up and down is arranged inside an upper die, the reset mechanism which pushes the material pushing block to slide downwards is connected on the upper end face of the material pushing mechanism, and the thrust mechanism which prevents the material pushing block from dropping off the upper punch is arranged inside the upper die. When a magnetic rubber sheet is punched and cut, the material pushing block slides upwards along the stroke cavity. After products are formed and in the short stroke during which the upper die returns back, the reset mechanism pushes the material pushing block to slide downwards opposite to the outer wall of the upper punch to enable finished products to be pressed and abutted against on a lower die until the material pushing block is limited by the thrust mechanism and returns back along with the upper die together, and therefore the finished products cannot arbitrarily move between the upper die and the lower die and also cannot drop off magnetic rubber raw materials. Magnetic rubber finished products are additionally collected along with the magnetic rubber raw material to move horizontally after the magnetic rubber finished products leave the range of the die, an operator does not need to conduct shutdown operation repeatedly, and therefore continuous production of the products is benefited and the production efficiency is improved. The composite stamping die is suitable for punch forming of the magnetic rubber sheet.
