Description

technical field [0001] The invention relates to an infiltration method, in particular to an infiltration method and device for large thin-walled parts, and belongs to the technical field related to the production of thin-walled parts. Background technique [0002] Impregnation is to infiltrate the sealing medium (usually a low-viscosity liquid) into the micropores (slits) through natural infiltration (ie, micropore self-priming), vacuuming and pressure, etc., fill the gaps, and then pass through natural (room temperature) methods. ), cooling or heating to solidify the sealing medium in the gap to achieve the function of sealing the gap. During the low-pressure casting process, defects such as micropores and blisters will occur due to the solidification volume shrinkage of the metal solution, impurities or gas residues. Defective castings may leak liquid and gas and become unqualified products. Especially for large thin-walled parts, if they are scrapped due to leakage, it w...

Problems solved by technology

However, the currently commonly used vacuum impregnation equipment has a complex structure and high cost, and is suitable for batch impregnation of small-sized products. For large thin-walled parts, due to space constraints, usually only one or two products can be impregnated at a time, and It is necessary to vacuum the entire vacuum impregnation tank, and then inhale a large amount of impregnation liquid to infiltrate the product, which takes a long time, is inefficient, and wastes the impregnation liquid. Therefore, an impregnation method and device for large thin-walled parts are now needed. help to solve the above problems
