摘要
以超薄壁复杂铝合金滤波器散热壳体（散热片最小壁厚为0.8-1.0mm）为研究对象,采用RSF半固态快速制浆压铸成形,运用MAGMA软件对壳体的半固态铸造成形过程进行了模流分析,探讨了不同压射低速值和压射高低速切换位置对半固态浆料流动和充型的影响。结果表明,当压射低速值为0.1m/s,高速值为3.5m/s,高低速切换位置为720mm时,可以得到完全符合技术要求的超薄壁铝合金滤波器散热壳体,并且对该工艺参数进行了实际生产验证。
The priduction of heat radiating shell of ultrathin-walled aluminum alloy radio filter with the heat sink in range of 0.8-1.0mm,was investigated by the RSF rapid slurry forming of semisolid die casting with the help of the MAGMA simulation software to analyze the forming process of semisolid die casting.And influence of different value of low/high injecting velocity and high speed switching positions on the flow and filling of semi-solid slurry was analyzed.The result reveals that with the low injucting velocity of 0.1m/s,the high injecting velocity of 3.5m/s and the high speed switching position of 720 mm,it can be satisfied for the technical shaping requirements of the heat radiating shell of ultrathin-walled aluminum alloy radio filter.And the process parameters were verified by the actual production.
