Process method for vibration casting molding of lost foam casting

Abstract

The invention relates to a process method for vibration casting molding of lost foam casting. The process method comprises high-frequency vibration mold filling, high-frequency vibration crystallization, low-frequency vibration crystallization and annealing. By adopting the process method, the compactness of an internal structure of a lost foam casting product can be improved, and fatal defects that the surface structure compactness is generated in lost foam casting and internal structure crystalline grains are coarse can be overcome; and meanwhile, the unqualified rate of castings can be reduced, the enterprise cost can be reduced, and the economic benefits can be improved.

Description

[0001] technical field [0002] The invention relates to the field of casting, in particular to a process method of vibratory casting for lost foam casting. Background technique [0003] In the field of modern machinery manufacturing, the foundry industry is playing an increasingly important role. In the commonly used lost foam casting, the castings cast by it are prone to fatal defects such as poor internal structure compactness and coarse grains in the internal structure, which makes it necessary to eliminate a large number of unqualified castings every year in engineering applications. Just increased enterprise cost, is not conducive to economic benefit. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a process method of vibratory casting for lost foam casting, which can improve the compactness of the internal structure of lost foam casting products, and avoid the phenomenon of dense surface structure and coar...
