湿型砂工装模具的计算机辅助设计

A CAD System for Patterns Design in Green Sand Technology

报道了研究的湿型砂铸造用工艺装备模具的ＣＡＤ系统；该系统以ＡｕｔｏＣＡＤ软件为基础，采用交互方式设计了铸件生成、型芯型腔设计、模样设计、芯盒设计、模板工装设计等功能模块。用户通过屏幕上的流程菜单调用各功能模块。还阐述了系统的功能、结构、运行流程及实现方法。

A CAD system for moulds and patterns in green sand casting has been developed.The function,structure,running procedure and realization of the system are described.The functional modules for part drawings,input,casting forming,core and cavity design,pat-tern design,core box design and pattern design are all to be run in an interactive mode. This system is based on Auto CAD softwares arid the source programs are written in FORTRAN and Auto LISP computer languages.The system can be run in an MS-DOS software environ-mem.
