The invention relates to a composite structure for an upper plunger chip and a lower plunger chip of a blade forming die, which comprises an upper plunger chip composite structure and a lower plunger chip composite structure. Both the upper plunger chip composite structure and the lower plunger chip composite structure comprise a plunger chip support and a fixing sheet arranged on the plunger chip support; a plurality of conical holes are arranged in the fixing sheet; and each conical hole is internally provided with a dismountable plunger chip sheet. As the plurality of dismountable plunger chip sheets are arranged in the composite structure for the upper plunger chip and the lower plunger chip of the blade forming die, the plunger chip sheets are convenient to replace; and the single plunger chip sheet can be replaced independently; therefore, the cost is saved; and the plunger chip sheet is convenient and quick to mount; moreover, the purpose of producing a plurality of plunger chip sheets can be realized through one-step punching on the plunger chip sheets during production; therefore, the production efficiency is greatly improved; the cost is saved; and the working intensity of workers is reduced.
Description
technical field [0001] The invention relates to a mold combination structure, in particular to a combination structure of upper and lower punches of a small blade forming mold. Background technique [0002] The combined structure of the upper and lower punches of the existing small blade forming die is usually brazed to weld each set of punches on the fixed piece, and the position between the punch pieces is easy to be deformed during this welding process, and the temperature is very high during welding , affecting the performance of the punch material. Therefore, the combined structure of the existing upper and lower punches needs to be further improved. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the purpose of the present invention is to provide a combined structure of the upper and lower punches of the blade forming die that can be replaced by a single punch, which saves costs and is convenient and quick to install, so that each gro...
