该机匣体为航空类产品,其材质为铝合金,该铸件的特点是结构复杂、薄壁且砂芯众多,该机匣体需用50多个砂芯才能完成其组芯造型。其叶片砂芯即为其中最主要的砂芯之一,因该砂芯为细薄的环状加层状结构,因而在热芯盒类芯盒的设计中其具有较为典型 The aircraft body for the aviation products, the material is aluminum alloy, the casting is characterized by complex structures, many thin-walled and sand cores, the machine requires more than 50 sand cores to complete its core shape. The blade sand core is one of the most important sand cores. Because the sand core is a thin annular plus layered structure, it has a typical shape in the design of a hot box core type core box
