重点阐述了锥形套注射模结构中脱模机构的设计要点。

Importantly, the design critical points of demoulding mechanism in the structure of cone - thimble injection mold are stated.

目前锥形套圈辗扩技术只能一次成形一件，而且由于锥形套圈锥角使得芯辊应力集中严重。

At present, the ring rolling technology roll one ring in one process, and the technology can't deal with stress focus on the sharp taper Angle of mandrel roller.

锥形套圈由于它截面形状的不规则性决定了辗扩过程金属变形的不均匀性，这是导致不规则宽展、拉凹的主要原因。

The taper ring's irregular section shape decide the unequal forming of the ring metal when rolling ring, which is the main cause of irregular wide spread and draw concave on the symmetry face of ring.
