HT200底座的铸造工艺设计
摘要:
随着我国机械工业生产的不断发展，铸造工艺技术已成为机械工人和技术人员在技术革新中的一项重要任务。掌握铸造工艺技术知识是现代机械类专业学生必不可少的。
本文通过对一个简单底座零件结构分析，并对其确定工艺方案，合适的工艺方案可以满足精度要求和各零件。根据整体的结构确定铸造工艺参数的。从零件的分析到最后浇注系统的设计，都经过了一系列的思考和分析。
关键字：底座铸造工艺，砂芯，浇注系统
Abstract：
With the continuous development of China's machinery industry, foundry technology has become a major task of mechanical workers and technicians in technical innovation. Master knowledge of casting process is essential to modern mechanical engineering students.
In this paper, a simple structure of the base parts is analyzed, and its determination process, the appropriate process can meet the accuracy requirements and parts. Determining the casting process parameters according to the overall structure. From the analysis of parts to the design of the casting system, it has been a series of thinking and analysis.
Key words: base casting technology, sand core, casting system
