介绍了弯曲型腔结构的管、阀类产品铸造后清砂的工艺方法
分析了各种方式的操作难点和型腔内、外层强度。以降低管状型壳层强度为出发点
提出在内腔部位涂撒覆膜砂的硅溶胶熔模铸造制壳工艺
可以有效降低内腔型壳强度
从而解决内腔型壳清砂难的问题。
Technologies for sand clean of investment casting pipe and tube with bending cavity were described
focusing on operation problems in different technologies.Inner and outer strength of cavity was analyzed.To decrease the strength of pipe shell mold
silica sol shell making was introduced by coating precoated sand in cavity
which could effectively improve the strength of shell mold
eliminating the problems in sand clean.
