Aimed at a series of bolt hole leakage in aluminum alloy cylinder head

the AnyCasting software was used to analyze the origination of the leakage problem

which was attributed to the generation of shrinkage porosities.According to the simulated results

the optimized schemes were designed such as cooling system optimization and product rounded corner structure optimization

and the feasibility of the modified scheme was verified by simulation analysis.The results show that

when the cooling opening time of side mold point is 50 sand waterjacket rounded corner is optimized to R7

the isolated liquid region at the leakage site basically disappears

then production verification was carried out with these schemes.The practical production reveals that the simulated results are highly consistent with the verification ones

and the product leakage rate is rapidly reduced from 3.5% to 0

which greatly reduces the cycle and cost.
