Abstract：Guide vane is an essential accessory for pump products.The flow channel is narrow and multi-layered.In order to ensure the product quality,the overall investment casting process is adopted.The mold is divided into 3 sets of molds,and the 3 parts are combined into a wax embryo product.Special grouting process is adopted in shell making to ensure that the guide vane runner will not be filled with iron after pouring,and it is convenient to clean the runner in the following process.And the reliability of pouring process design is simulated by Procast simulation software,so as to ensure the quality of products.
