Improvement of Cold-core Water Jacket Technology of Thin-walled Lightweight Engine Cylinder Head
This paper introduces the quality improvement and application of the cold core technology development process for water jacket sand core of 11 L cylinder head.Based on the shortcomings of the original hot core process,from the cold core process and tooling design,and the use of CAE sand shooting simulation analysis to optimize the sand shooting and exhaust system,through multiple rounds of different feedings to facilitate verification,the process parameters that can meet the requirements of mass production of complex structure water jacket cold core process are obtained,and the quality and size of the test cooling core sand core and castings have been significantly improved.At the same time,the core production efficiency is improved,the dimensional accuracy of the casting is stable and reliable,and the performance of the whole machine is effectively improved.It provides a reference for the popularization of water jacket sand core cold core technology of complex structure cylinder head.
