汽车制动钳体是制动系统的关键零件,其铸件品质要求高,在生产中易产生缩孔缺陷。通过分析铸件冒口颈缩孔产生的原因,结合计算机凝固数值模拟,优化浇注系统和冒口设计,实现浇注液流均匀,冒口充分补缩,有效地解决了铸件冒口颈缩孔问题。 Brake caliper body brake system is the key components, the casting of high quality requirements, easy to produce in the production of shrinkage defects. By analyzing the causes of casting riser neck shrinkage, combining with the numerical simulation of computer solidification, the design of casting system and riser is optimized, the pouring flow is even and the riser is fully compensated, which effectively solves the problem of riser neck shrinkage.
