The technical scheme that its technical problem that solves the utility model adopts is: a kind of stepped ramp type product material returned thimble main mode structure that connects material, comprise main die sleeve, the bottom of described main die sleeve is provided with rear pad, the inside of rear pad is provided with the pusher centre hole, pusher centre hole inside is provided with the pusher thimble, the pusher thimble comprises head and bar section, bar section is provided with spring between head and the rear pad, at rear pad top, pusher thimble outside and main die sleeve inside are provided with the more intermediate annular lining, be provided with the alloy mould at more intermediate annular lining top, alloy mould inside is provided with the centre hole that connects material, the connect material inside of centre hole is provided with the thimble that connects material, and is provided with the alloy matrix at alloy mould top, and main die sleeve front end is provided with alloy matrix installing hole, the alloy matrix is installed in the alloy matrix installing hole, and the alloy matrix is looped around the periphery of the thimble that connects material.
For alloy matrix and main die sleeve are cooperated closely, described alloy matrix and alloy matrix installing hole cooperation place are gradient, and its gradient is 10 °.
For convenient fixing main die sleeve and rear pad, be provided with swivel nut between described main die sleeve and the rear pad.
Further concrete, the described centre hole that connects material is counter sink, and the thimble that connects material comprises thimble head and thimble rod section, and the thickness of thimble head is consistent with the countersunk head degree of depth of counter sink; The height sum of described alloy mould and alloy matrix is than the short 0～1mm of the length of the thimble that connects material.
The beneficial effects of the utility model are: adopt spring material returned thimble to connect material behind the main mould, die life is long and cost is low, if damage parts, only need local replacing just, do not need integral replacing, require also low to the skilled worker, easily accent machine, and product quality and outward appearance also increase substantially.
