J1116型压铸机分罐式压射增压装置主体设计 摘要 1116型压铸机是合型力为1600kN（160吨）的卧式冷压室压铸机。压铸机运行过程中，压射装置将注入压铸室中的金属液按照先充满压铸室的同时确保不能从注入口外溢且尽量将内腔中的气体排出，再快速充型之后保持较高的压力以有效补充型腔中的金属液因为冷却和凝固而产生的体积收缩，待铸件及浇注系统完全凝固之后，压射装置回程等待进入下一循环过程的流程进行压铸机的制备。本设计主要对J1116型压铸机分罐式压射增压装置主体及相关零件加以设计，J1116型压铸机分罐式压射增压装置主体装配图及其零件图。 关键词：压铸机；压射装置设计；增压装置 Abstract 1116 die casti
