Embodiment Construction

[0037] The invention provides a casting process for a complex aluminum alloy shell of an aero-engine. The casting process for a complex aluminum alloy shell of an aero-engine comprises the following steps:

[0038] 1) Analyze the structure of the complex aluminum alloy shell to be cast to determine whether there is a mixed shell in the complex aluminum alloy shell to be cast, and if so, proceed to step 2); if not, exit directly; the mixed shell is unsealed The top-to-bottom superposition of shells that require high density and compactness requires shells;

[0039] 2) For shells without airtightness requirements, use sand casting process to form sand molds; for shells with compactness requirements, use metal mold casting process to form metal molds; wherein, the specific implementation method of sand molds is:

[0040] a1) The mold has no sealing requirements. The shell adopts the sand casting process to form a sand mold; the sand mold includes sand molds and sand cores that ar...

Abstract

The invention belongs to the technical field of aluminum alloy casting, and relates to a casting process and mold for a complex aluminum alloy shell of an aero-engine. The process comprises the stepsof analyzing the structure of a to-be-cast complex aluminum alloy shell to judge whether a mixed shell exists or not, wherein the mixed shell is composed of a shell without sealing requirement and a shell with compactness requirement which are stacked from top to bottom; carrying out a sand casting process on the shell without sealing requirement to form a sand casting mold; carrying out a metal mold casting process on the shell with compactness requirement to form a metal casting mold; closing the sand casting mold and the metal casting mold to obtain a mixed casting mold; carrying out mold flow analysis on the obtained mixed casting mold for optimizing the mixed casting mold; manufacturing a mold object; and casting the mold object to obtain a finished product. The invention provides thecasting process and mold for the complex aluminum alloy shell of the aircraft engine, which have good casting quality and high mechanical property and can realize the aims of hollow structure formingand reduced-weight manufacturing of the shell of the aircraft engine.

Description

technical field [0001] The invention belongs to the technical field of aluminum alloy casting, and relates to an aluminum alloy shell casting process and a mold, in particular to a complex aluminum alloy shell casting process and a mold for an aero-engine. Background technique [0002] The aluminum alloy shell of the fuel accessories of the aero-engine has the characteristics of precision and light weight, and most of them have the characteristics of complex structure, uneven wall thickness, hollow structure, and many casting oil channels. The performance and technical indicators of the aluminum alloy shell are very high, and the pressure chamber often needs to undergo very high strength tests and air tightness tests, which require that the casting must have a relatively high structure density, and the solenoid valve shell part The requirements for the compactness of the structure are slightly lower, and it is a complex aluminum alloy shell with different functions. In the ...
