[0002] Prior art discloses a stamping method and die for producing fuel tank connector inserts. Patent number: 201910654259.0; filing date: July 19, 2019. The die comprises an upper die, with an upper die core mounted within the upper die and a lower die core mounted within the lower die. The facing surfaces of the upper and lower die cores correspond one-to-one, and the shapes and positions of the upper and lower die cores correspond to the first through fifth stations. This die, used for stamping fuel tank chucks, has the upper and lower dies directly fixed to the upper and lower die bases, respectively. This drawback is that the integrally assembled die assembly suffers from low precision, prone to assembly and machining errors. This results in low dimensional accuracy in the produced fuel tank connector insert (chuck), making it difficult to maintain stable production over extended periods. Utility Model Content
