球铁件浇冒口计算机辅助设计系统的综合研制及其实用化

Studies and Application on the CAD System of Gating and Risering Design for Ductile Iron Castings

根据浇冒口设计理论和生产经验,开发了适用于球铁浇冒口系统设计的FTCAD软件。该软件可进行铸件模数和重量计算、厚大断面铸件的无冒口设计、中小件冒口设计及绘制模板布置图和浇冒口系统图。在生产应用中能提高工艺出品率,具有明显的经济效益。

Abstract Based on design theories of gating and risering system and practical experience, was developed a software FTCAD suitable to design of gating and risering system for ductile iron castings which can calculate the modulus and weight of castings, design the riserless castings with heavy section and the gating and risering system of medium or small castings, also can draw the pattern plate layout and gating and risering system. The application of the FTCAD was said to increase the casting yield and has remarkable economical profits.
