| 内容： | To provide a new lost wax pattern for casting with which an inner barrel part, an outer barrel part and ribs are integrally formed, and a method for producing the casting with which an accurate gap between the inner barrel part and the outer barrel part can precisely be formed by using the lost wax pattern. ! This lost wax pattern for casting, is integrally formed with the wax to the almost cylindrical inner barrel part, the almost cylindrical outer barrel part inserting the one side end of the inner barrel part and the plurality of ribs connecting the outer barrel part with the inner barrel part, and ceramic cores are arranged as casting cores having the shape corresponding to the gap part between the ribs and the divided shape in the peripheral direction at the position formed between the adjacent ribs and corresponding to the gap part between the ribs penetrated along the axial direction of the inner barrel part. Further, the method for producing the casting, is integrally cast and formed of the inner barrel part, the outer barrel part and the ribs using the ceramic cores. ! (C)2007,JPO&INPIT |
