学位sing drawing, and the statement calculation. The casting technology mainly includes the process plans and parameters, besides the design of sand core and gating system. These must be based on the calculation of the original part 's size and structure to complete.
The foundry tools design comes after the casting technology design. It is mainly the design of the pattern and pattern plate. The pattern is the indispensable part in the modeling industry, used to form the mold cavity, and it has a direct relationship with the shape and dimensional precision of mold. The pattern plate, also known as plate, is assembled by the pattern mounting plate, the pattern, the pouring system, the guide pins and so on. Its design is based primarily on: the identified process drawing, the selected molding machine, the number of molds in the box and the feasibility of processing of the pattern plate. The size and fitting of pattern and plate are mainly considered in foundry tools design.
We used a hot box when choosing a core box. Therefore, the final work is the design of the hot box. The hot-core box has sand-shooting mechanism, exhausting mechanism, heating and core-drilling mechanism, besides the common structure of metal core-box. We can determine the size and type of the core-making machine on the basis of the shape and structure of sand-core, which could be confirmed in the casting processing drawing.
Key Word: casting technology design; foundry tools design; pattern; plate; sand-core; hot-core box

铸造工艺设计的概念
铸铁件广泛的应用在装备制造业，冶金，建筑，农机，给排水以及国防工业各部
门，如在机械制造业中，铸铁件所占比重约为机械重量的 40%至80%。生产的铸件是 多种多样的，质量有大有小，厚度可以薄到 2mm,也可以达到500mm,可以是各种形 状。那么什么是铸造呢？铸造工艺设计又是怎么设计的呢？现代科学技术的发展，要 求金属铸件具有高的力学性能、尺寸精度和低的表面粗糙度值；要求具有某些特殊性 能，如耐热、耐蚀、耐磨等，同时还要求生产周期短，成本低。因此，铸件在生产之 前，首先应进行铸造工艺设计，使铸件的整个工艺过程都能实现科学操作，才能有效 地控制铸件的形成过程，达到优质高产的效果。
铸造工艺设计就是根据铸造零件的结构特点、技术要求、生产批量和生产条件等，
