摘要
针对铝合金盘类零件在压铸生产中存在针孔、冷斑、流痕和大平面变形等问题,在分析其压铸工艺的基础上,对压铸模具进行了设计。根据结构特点,采用了多杆均布、扁平连接槽的设计,并采用较大面积和较宽的内浇口,实行慢浇和快速高压并保压的工艺。生产实践表明,改进后的方案能有效地减少铸造缺陷,提高了产品的合格率。
There exist problems in the practical die casting aluminum alloy disc parts,such as pin hole,cold spots,flowing mark and large plain deformation.A new die-casting die based on the analysis of die casting process was designed.According to the structural characteristics,uniform multi-rod and flat connecting groove were designed and inner gate with a larger area and width was used.The process of slow casting with rapid high pressure and pressure holding was also applied.The practical production shows that the improved scheme can reduce the casting defects effectively and improve production qualification rate.
