摘要

应用数值模拟和试验研究相结合

以典型的关公艺术铸件为例

分析真空吸铸技术在艺术铸造领域应用的可行性

并探究真空吸铸成形中空薄壁艺术类铸件的浇注工艺方案设计。结果表明

该工艺可成功铸造出表面无缺陷的完整中空薄壁艺术铸件

且满足艺术品工艺要求。在充型速度为60 mm/s、吸铸温度为710℃、铸型温度为350℃的条件下可获得轮廓完整、纹理清晰、棱角分明的关公艺术铸件。

Abstract

The combination of numerical simulation and experimental research was used to analyze the feasibility of vacuum suction casting technology in the field of art casting by taking typical Guangong art castings as an example

and the pouring process design of vacuum suction casting hollow thin-walled art castings was explored. The results show that the process can manufacture successfully complete hollow thin-walled art castings with absence of defects on the surface

which meets the requirements of art crafts. With filling speed of 60 mm/s

the suction casting temperature of 710 ℃ and the mold temperature of 350 ℃

the Guangong art castings with complete contours

clear texture and sharp edges were obtained.
