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 technologies, lightweighting vehicle body components has become a key path to achieving vehicle energy conservation and emission reduction goals. To meet the demands of lightweighting, integration, and high performance, key automotive components are evolving toward thinner walls, greater complexity, and larger sizes. The application of die-casting in vehicle body components is also gradually expanding from small parts to large, complex, integrated components. Integrated die-casting technology, by integrating multiple aluminum alloy components into a single, large-scale structure, not only significantly improves structural integration and production efficiency, but also effectively reduces manufacturing costs, contributing to vehicle weight reduction.

[0003] However, integrated die-castings are typically large in size, complex in structure, and have dramatic variations in wall thickness. The filling paths and thermal histories of different regions during the die-casting process vary significantly. This difference in process conditions directly affects the flow behavior and solidification process of the molten metal, leading to 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. Therefore, there is an urgent need to build a set of detection equipment systems that can truly reflect and simulate the filling behavior of molten metal in complex, thin-walled cavities over long processes. This system can be used to conduct research on forming capability assessment, structural optimization verification, and regional performance prediction, providing basic support for the development of high-quality integrated die-castings.

By observing the filling of the metal melt in the step structure and analyzing the quality of the die castings at different steps, we can judge and study the filling capacity of the alloy melt with variable cross-section.

[0045] In one embodiment, if Figure 8 As shown, the rib structure cavity 1-4 includes a plurality of rib plate channels, which are arranged in a crisscross pattern, and the thickness of each rib plate channel is not fixed.

After the die-cast component is formed, the die-cast component with through-hole characteristics (such as Figure 9 (as shown in the figure) is used to map the assembly through-hole structures in large, integrated die-cast components. The diameter of the porous obstruction structures ranges from 15mm to 35mm. By analyzing the changes in microstructure and pore defects before and after the pillar wrapping, the filling characteristics of the molten metal in large, complex cavities can be reflected. Observing the filling conditions before and after the pore wrapping and analyzing the casting quality can determine the filling capacity of the alloy melt in complex cavities.
