Application of Squeeze Casting in Hybrid Car Suspension
Aiming at the suspension fracture problem of hybrid car produced by gravity casting,the application of squeezing casting in producing hybrid car was mainly analyzed.During the design process of squeezing casting die,the local squeezing pin diameter was modified from φ18 mm to φ16 mm to solve the problem of squeezing pin stuck,and the ingate was shifted to 15 mm from the maximum stress area of the casting.The parts produced by the mold were qualified with high safety margin.The tensile strength and yield strength of suspension by metal gravity casting and squeezing casting are similar,while the elongation is increased by over 100％,greatly alleviating the risk of brittle frac-ture caused by impact.In the light weight approach,squeeze casting can replace forged aluminum and cast iron parts.
