The fluid material takes the shape of the diecavity and this geometry is finally stabilized by the solidification of the material.
液体材料充满型腔，随着材料的凝固，零件的几何形状最终固定下来。

So it adopt cubic spline function to structure diecavity outline in this article, the model points may be surveyed on diecavity surface.
因此，这里采用三次样条函数拟合曲线构造模具型腔廓线，其型值点由已有模具型腔测得。

The temperature-time curve of the heated diecavity and the relation between temperature and time under different initiatory temperature were determined.
