摘要
介绍了导轨钻机铝合金壳体金属型重力铸造模具的设计过程。在模具的设计制造过程中,运用CAD/CAM计算机辅助技术,并进行了浇注过程的计算机模拟(CAE),发现浇注成形时可能出现的缺陷,并进行合理的改进。针对在试模过程中所出现的砂芯偏心、铸件缩松缺陷,改进了树脂砂芯芯头结构和冒口高度,将模具温度控制在200℃左右和金属液温度控制在750℃等措施,得到了合格的铸件。
The design of permanent mould for aluminum alloy drill housing of guide-rail in gravitational casting was described. During deigning and manufacturing process,the CAD/CAM was employed to simulate the filling process to observe the potential defect generation during filling, and rational improvement was conducted. Resin sand core-end structure and runner height were adjusted to eliminate the eccentric sand core and shrinkage porosity (hole) occurred in trial-mould process, meanwhile, mould temperature is controlled at about 200 ℃ with temperature of liquid metal at about 750 ℃. The qualified aluminum alloy housing was produced by adopting above-mentioned measures.
