The course of action of described shaping mould is: when its upper end does not stresses, fanning strip mould 8 is due to the elastic force of helical spring 10
Effect keeps at grade and decile opens, and facilitates product to enter.Gap between every two panels fanning strip mould 8 is equidistant, interior
Hole increases, it is ensured that have sufficient space to enter for product.When shaping mould upper end is by external force effect, three fanning strip moulds 8 are at tapering
Moving down under the constraint of set 7 and gradually closing up, product stress upsetting is molded.
During work, due to the effect of fanning strip mould 8 internal helicoid spring 10 elastic force, three fanning strip mould 8 stress are opened, and
Uniform.Its upper surface is maintained on same surface, and the effect of back-up ring 12 is to prevent fanning strip mould 8 from skidding off coning sleeve 7, now, fan
Shape piece mould 8 is in open configuration, this guarantees shaped piece 11 its afterbody before making and can enter mould.Make process
In, shaped piece 11 enters open-close module, and fanning strip mould 8 stress moves down along coning sleeve 7, and three fanning strip moulds 8 gradually close up, folding
The core of mould moves down compression butterfly spring 6 under the effect of the pressure, and the stress crimp of shaped piece 11 stage casing, in forming
Recessed, when removing external force, lower thimble 22 upwards moves, and butterfly spring 6 is upheld, and shaping mould moves up and withstands formwork 4.Upper thimble 21
Shaped piece 11 is pushed up to outside by stress, and fanning strip mould 8, by the tractive force effect of internal helicoid spring 10 and shaped piece 11, upwards moves
Dynamic decile opens, until contacting with back-up ring 12, shaped piece 11 separates with mould.Product upsetting is molded.
Above example simply elaborates general principle and the characteristic of the present invention, and the present invention is not limited by above-mentioned example,
Without departing from the spirit and scope, the present invention also has various change and changes, and these changes and change both fall within
In scope of the claimed invention.Claimed scope is defined by appending claims and equivalent thereof.
