- 摘要:
- 采用复杂铸件无模复合成形技术快速制作砂型模具,通过设置3D打印检具直接控制铸型组装精度和砂型坎合结构间接控制铸型组装精度两组对比试验,研究了两种控制方式的组装精度误差。通过扫描分析研究了砂型组装后型芯的偏心距D。结果表明,通过3D打印检具直接控制组装精度的方式,偏心距误差值最小,可获得组装精度较高的铸型。Manufactured sand molds with complex patternless casting.Set up two group of contrast experiments which are positioned directly by 3D printing checking gauge and indirect position structure to compare sand mold assemble positioning precision.By scanning and analysis the deviation of the sand core and mold after assemble,the results shows that the deviation by 3D printing checking gauge is the smallest among the two methods,thus is the better way to control positioning precision of sand mold.
