clamping plant/unit is ensure mold can 靠闭紧 and achieve mold 启闭动 as and ejection products parts. good clamping plant/unit must tool 备三方面 features: (1)足够 combined mold force and system rigid property, ensure mold in material pressure lower, generate 开缝溢 material phenomenon: (2)足够 安装 mold and mold 行程:   (3) fast speed speed degree and relatively slow combined mold speed degree, 移模时 need tool slow fast slow features.
     clamping plant/unit types type relatively more, various different clamping plant/unit its features focus/key point different. currently use most has pressure pressure, pressure 肘杆式 and electrical 动肘杆式, for/regarding different liquid distribution and structure also can separation very multiple.

油 pressure pressure 式直接 through 锁模油缸 推 force (or force) mold. clamping force and function force versus and other. this type of clamping plant/unit features is can in molding deep products provide relatively 持久平稳 mold opening force. pressure 肘杆式 clamping plant/unit clamping 油缸推动连杆 machine 构, again through machine 构 放 large function 推动模 sheet/plate and combined mold, can achieve fast speed low can consumption clamping. lower separation 别予以 introduction.
油 pressure pressure clamping plant/unit
     many machine type 移模油缸设 in 锁模尾 sheet/plate in 部, 闭模时．移动模 sheet/plate by front 移, and sheet/plate versus 连 四根顶柱便 from sheet/plate to 离开闸门 sheet/plate 位置, 此时闸门 sheet/plate 油缸驱动闸门 sheet/plate 旋转, will 四根顶柱往尾 sheet/plate 退入 位置顶住, make high pressure 油缸定位, most rear high pressure 油缸推动顶柱 combined mold. mold opening 时首先由 high pressure mold opening active 塞杆拉动模 sheet/plate to setting 位置, rear 由移模油缸 fast speed mold opening. for/regarding certain products, assembly need 一段几乎没 has 拔模斜 degree structure, if high pressure mold opening mold opening to 由移模油缸 mold opening, 会出现 mold 打开一点 rear 移模油缸打不 mold opening phenomenon, this need through rear and adjustment high pressure mold opening make high pressure mold opening 油缸起 function add long, from provide mold opening force. this type of clamping structure features has:   (1) due to high pressure clamping 油缸处于模 sheet/plate in 间, 不会出现 due to sheet/plate bending products flash; (2) mold opening large mold opening force stability, can molding deep products;   (3) due to sheet/plate and its as 切换以 and high pressure mold opening and 移模油缸 in mold opening 时 动 as consumption relatively more, difficult achieve high speed 开闭模循 ring.
     another, has small type precision liquid pressure injection molding machine due to clamping 顶柱, high speed clamping 时由充 liquid 油缸供油, decrease/reduce sheet/plate as time, make clamping ring time large large shrink short, but also 不需调模.
    油 pressure pressure clamping plant/unit clamping force 直接由 combined 紧油缸 provide, its large small 由油缸 function 面积以 and pressure 决定. in 油缸直径 already 定 情况 lower, can through increase large pressure add large clamping force.
    油 pressure 肘杆式 clamping plant/unit     ,
     many company machine is using/adopting pressure 肘杆式 clamping plant/unit, separation is 五点斜排式 or 四点斜排式, this is currently most formed 熟 油 pressure 肘杆式 clamping structure.
     in in, machine tool has relatively large ratio 系数(即行程放 large 倍数) and relatively small force large 倍数. in mold will combined 紧时, machine force expand large 倍数急剧 increase large, 而行程 ratio decrease/reduce
this 样, use relatively small relatively short clamping force 油缸, can to relatively large clamping force and 移模行程. and machine 构本身 运动 features tool has slow fast slow features, in high speed clamping for force control system requirements high.
     in pressure 肘杆式 clamping plant/unit upper, due to 联结连杆 销轴 need in 旋转运动 meanwhile relatively large surface pressure and force. for its 材质, strong/high degree, surface hardness and lubricated has relatively high requirements.
     versus for/regarding pressure pressure clamping plant/unit; pressure 肘杆式 tool has speed degree fast, speed 平稳, power/electricity, ultra- 载 property can good and other advantages, meanwhile has can molding deep products, relatively complex, clamping force heavy degree high, for mold degree requirements relatively high and other 局限. in selection machine 时, need according to above features and products features and requirements use types plant/unit.
