摘要

通过传热学理论找到了液态金属凝固结束时型内温度变化规律，从而解决了低压铸造保压延时难以控制的问题。

Abstract

this paper has found out the law of temperature variety in the impression by heat transfer theory when liquid metal has been solidified. This solves to be difficult to control the problem during the pressure maintaining and time-delay.
