Optimization Design of Die Casting Process for Automotive Alloy Support Frame

Aiming at the problem of low defects rate in automobile engine aluminum alloy fuel filter support frame die-casting production and lower qualified rate. The Pro CAST numerical simulation software is used to predict the process of die casting and shrinkage defects, according to the simulation results, determine the reasonable casting solution, using orthogonal test to determine the best process parameters. The results show that the fuel filter support frame best die casting technology parameters is for mold preheat temperature 200 ℃, injection speed 1 m/s, pouring temperature 630 ℃,application design and the optimal process parameters, complete casting die casting production and processing, get the casting quality is good, the effect is ideal through pressure test.
