①油路 system need using/adopting ratio/proportion pressure 阀, ratio/proportion amount or ring amount system.

injection molding machine liquid pressure system need using/adopting ratio/proportion pressure 阀, ratio/proportion amount 阀, achieve system different as pressure and amount. is amount liquid pressure system, also is amount liquid pressure system, in ratio/proportion 阀, control 油泵输出 工 as pressure and as amount, achieve ratio/proportion property adjustment.

② in pressure clamping machine in, clamping separation and injection separation separation 开.

this type of requirements for pressure injection molding machine 而言, is pressure injection molding machine is in clamping high pressure rear 瞬间, injection melt, filling mold type 腔. and meanwhile, must has liquid clamping 油缸, formed clamping high pressure.

否则 in sheet/plate 会因受 to pressure and force function rear 退, this is 不允许发生. this requirements clamping and injection separation 离, 否则会发生因油 liquid meanwhile clamping and injection 油缸而发生油泵 载 issues, and effect/influence injection speed degree and system stability property.

③ due to precision injection molding machine tool has high speed property, is must strong/high liquid pressure system speed degree.

precision injection molding more is in high pressure and high speed lower formed （ connectors or machine 按键）, time non short, generally has 零点几秒, this requirements system tool high property can, 否则出现响应迟滞 phenomenon, most 终导致 system 输出信号 and 输入信号 requirements relatively large, molding process debugging difficult, production in 也会直接 effect/influence made parts dimensions or weight stability property.

injection molding machine high property 取决于 control device time, 油泵 响应 time, 油阀 响应 time. for/regarding add 装伺服阀 liquid pressure system, in 响应方面 and heavy degree 方面就 has versus advantages.

for/regarding amount injection molding machine, is pressure and amount 输出, is through 油泵斜盘摆角 adjustment, therefore tool high property and high property, heavy degree can to 0.2% below/following.

④ precision injection molding machine liquid pressure system, need separation machine — electrical — liquid —仪一体 chemical industry 程.

currently injection molding machine using/adopting full electrical control, function 逐渐完善, tool 备“人 machine for 话”, fault/failure diagnosis, molding 状态监控, SPC quality and other can function. injection molding machine liquid pressure system is injection molding machine as 发生 动 force parts, control device is liquid pressure system tube/pipe in 心, type table/sheet is machine 台运行状态 辅助监控部 separation. injection molding machine its is machine, electrical, liquid, has machine combined can 体.
