The invention belongs to the technical field of demoulding tools and particularly relates to a tool structure for demoulding an engine nozzle diffuser. The tool structure comprises a demoulding upperring, a demoulding lower ring and a plurality of pull rods; the demoulding upper ring takes a plate shape; a first connecting part is arranged in the middle of the demoulding upper ring; a hoisting ring is arranged above the first connecting part; the demoulding lower ring takes a plate shape; a circular hole is formed in the middle of the demoulding lower ring; a gap is arranged on the circumferential edge of the circular hole; an adjusting part is further arranged on the demoulding lower ring at the gap and is suitable for adjusting the size of the circular hole through adjusting the size ofthe gap; one end of each of the pull rods is connected with the demoulding upper ring; and the other end of each of the pull rods is connected with the demoulding lower ring. Through the structure, the engine nozzle diffuser with a large size and a thin-wall structure can be easily demoulded from the core die of the diffuser without damaging the self structure, and the tool structure is high in practicality.
本发明属于脱模工装技术领域,具体涉及一种用于发动机喷管扩散段脱模的工装结构,包括:脱模上环,所述脱模上环呈板状,且中部设有第一连接部,所述第一连接部的上方设有吊环;脱模下环,所述脱模下环呈板状,且中部设有圆孔,所述圆孔周沿上设有缺口,所述缺口处的所述脱模下环上还设有调节部,所述调节部适于通过调节所述缺口的大小以调节所述圆孔的大小;拉杆,所述拉杆的数量有多根,多根所述拉杆的一端与所述脱模上环连接,另一端与脱模下环连接。通过上述结构,能够轻松地将大尺寸、薄壁结构的喷管扩散段与其芯模脱模而不会破坏其本身结构,实用性强。
