Description

Technical Field

[0001] The present application relates to the technical field of die-casting mold structures, and in particular to a forming performance detection equipment system for long-process complex thin-walled die-casting parts of aluminum and magnesium alloys. Background Art

[0002] With the rapid development of new energy vehicle technology, lightweighting of vehicle body structural parts has become one of the key paths to achieve the energy conservation and emission reduction goals of the entire vehicle. In order to meet the needs of lightweight, integration and high performance, key automotive components are evolving towards thin-walled, complex and large-scale, and the application of die-casting technology in vehicle body structural parts has gradually expanded from small parts to large and complex integrated structural parts. Integrated die-casting technology integrates multiple aluminum alloy structural parts into a single large structural part, which not only significantly improves the structural integration and production efficiency, but also effectively reduces manufacturing costs, helping to reduce the weight of the entire vehicle.

[0003] However, integrated die castings are usually large in size, complex in structure, and with dramatic changes in wall thickness. There are significant differences in the filling paths and thermal histories of different regions during the die casting process. This difference in process conditions directly affects the flow behavior and solidification process of the molten metal, which in turn leads to the formation of differentiated microstructures and mechanical property distributions in different regions, becoming a key factor restricting the performance stability and quality consistency of large integrated die castings.
