Automotive lamp bracket die-casting process analysis and mold design

Original title: automotive lamp bracket die-casting process CAE analysis and mold design

Analyzed the structural characteristics of the automotive lamp bracket, carried out the die-casting process design, and the application of ProCAST software on the aluminum alloy die casting filling process, die casting die heat balance and temperature field numerical simulation analysis, predict the location and cause of defects, according to the prediction of the results of the optimization of the mold structure. Actual production shows that the use of optimized mold design scheme to improve the quality of castings.

Lamp bracket parts are an important part of automobile lamps, which need to have sufficient strength to support the lamp housing, and need to have high stability and corrosion resistance to ensure that they can be firmly, precisely and stably fixed on the body of the car to ensure the safety of night driving. Aluminum alloy has been widely used in the lamp bracket because of its good performance. However, due to the uneven wall thickness and complex structure of the lamp bracket, it is easy to produce defects such as shrinkage and loosening and cold segregation during the die-casting production process, which can't meet the requirements of safe driving of the car. In order to improve the comprehensive yield of a company's aluminum alloy lamp bracket, this study for the lamp bracket parts die-casting forming process, based on ProCAST casting filling solidification process CAE analysis, and for the possible defects to improve the die-casting process and mold design, improve product quality.
