Closed has carried on the reasonable determination highly to the mold, but also designs the mold the major parts to fall the material concave mold, the convex-concave mold, the counter- drawing raised mold, the counter- drawing concave mold, the concave mold dead plate and so on.

对模具的闭合高度进行了合理的确定，还设计出模具的主要零件落料凹模、凸凹模、反拉深凸模、反拉深凹模、凹模固定板等。

Certain mold components (for example convex-concave mold) the shapeand the size by the product decided thus is unable in the moduledesign time foresees, therefore only can according to the common shapedesign module (for example circular or rectangular drift), is suitablethe surface to be narrow; Certain mold components (for example flush压模work piece localization components) although mutuallycoordinates to carry out some function, but their space arrangesdifficult to seek the rule and the general character, therefore evenif divides according to the function cannot have the module.

某些模具零件的形状和尺寸由产品决定因而无法在模块设计时预见到，所以只能按常见形状设计模块，适用面窄；某些模具零件（如冲压模的工件定位零件）虽然互相配合执行某一功能，但它们的空间布置难寻规律与共性，因此即使按功能划分也不能产生模块。

The properties of the materials used for making models of sodium silicate bonded sand core curing by microwave energy are suggested.

结果表明，塑料模具和陶瓷模具都可用于水玻璃砂芯的微波固化。

This is a compound mould of metal type. Cast iron is utilized to make the two moulds. The pour system of this mould is shaped by sand core.

本模具是金属型复合模具，其上下两模采用铸铁，而其浇注系统是用砂芯形成。
