全立式压铸机的改造与实践

摘要

Hydraulic circuit and circuit of YTD32-100 type four-column hydraulic machine were redesigned, and it was transformed into the whole vertical die casting machine. Mode -locked oil and injection circuit were independent of the machine. It was convenient to adjust injection pressure, holding pressure time, filling time and other process parameters. The explosion-proof vibrator shell was produced by the machine, and the casting qualified rate reached 90%.%对 YTD32-100型四柱式液压机的液压油路和电路进行了重新设计，将其改造成为全立式压铸机。该机有独立的锁模油路和压射油路，可以方便调节压射比压、保压时间及充型时间等工艺参数。应用该机压铸出了防爆震动器壳体，铸件合格率达到了90%。
