摘　　要：介绍了熔模铸造工艺特点,压型型腔尺寸的计算方法。及旧模料回用处理和水玻璃预处理的机理与方法,指出在压型设计时,通过公式L=l(1+Δl)±(1/2～3/4)ΔM计算出来的尺寸数据是可靠的。The features of investment casting process, dimensions calculation method of the pattern die cavity, as well as the principle and method of returned pattern wax reclamation treatment and pretreatment of sodium silicate solution was introduced. It was pointed out that, during design process of the pattern die, the dimension data obtained by calculating with the formula of L=z（1＋△l）±（1/2～3/4）△M are reliable.
