In the material gathering die structure, the inner cavity of the upper pre-upsetting die barrel 3 is in contact with a high-temperature workpiece for a long time, and the abrasion is serious. And the pre-upsetting upper die barrel 3 can be continuously used only by integrally replacing after being damaged, and half-shaft parts meeting the requirements are processed, so that the waste of die materials is serious.
For solving the problem that the mould material is wasted seriously because the upper die barrel 3 in the pre-upsetting mode can only be integrally replaced after being damaged, the embodiment provides a half-shaft forming material gathering mould which has the structure as shown in attached figures 4-7. The half shaft forming material gathering die comprises a die cylinder connecting cylinder 1, an upper die connecting cylinder 2, a pre-upsetting upper die cylinder 3 and a connecting gasket 5. Wherein, the upper die connecting cylinder 2 and the pre-upsetting upper die cylinder 3 are arranged at the hollow inner side of the die cylinder connecting cylinder 1.
