Shanghai Daoqin Plastics Co., Ltd.

         plastics injection molding machine 基础 Knowledge has which. injection molding machine tool has can one-time molding outer type complex, dimensions or belt/tape has metal parts 质 密致 plastics products, by 广泛于 national defense, machine electrical, automotive, 交通运输, building materials, packaging, 农业, 文教卫生 and day active field/area. injection molding process for various plastics processing tool has good property, production can force relatively high, easy achieve 自动化. in plastics industrial speed development 今天, injection molding machine in amount upper or product types upper has important 位, from formed is currently plastics machine in growth most fast, production amount most more machine types 之一.

         plastics injection molding technology is according to pressure principle from 十九世纪末二十世纪初 development 起, is currently plastics processing in most using/adopting methods 之一. method suitable for full thermoplastic property plastics and separation hot solid property plastics (约占 plastics amount 1/3).

         injection molding machine as principle, injection molding machine as principle and use injection device versus 似, it is screw (or 柱塞) force, will already good melt 状态(即 viscous 流态) plastics injection combined good mold cavity inner, solid type rear products process process.

         injection molding is 一 循 ring process, cycle main/primary 包括: amount add material —熔 melt 塑化—施 pressure injection —充模 cooling —启模取 parts. 取出塑 parts rear also again 闭模, lower 一 循 ring.

         injection molding machine structure, injection molding machine according to methods separation is 柱塞式 injection molding machine and screw injection molding machine;按 machine methods also can separation is liquid pressure 式, machine and liquid pressure — machine 械(连杆)式;按操 as methods separation is 自动, semi 自动, injection molding machine.

        (1)卧式 injection molding machine: this is most Common type type. its clamping separation and injection separation 处于同一 water in upper, mold is water direction 打开. its features is: machine 身矮, easy as and repair; machine heavy low, relatively 平稳; products ejection rear can utilizing heavy force function 自动落 lower, easy achieve full 自动操 as. currently, market upper injection molding machine more using/adopting types type 式.

        (2)立式 injection molding machine: its clamping separation and injection separation 处于同一垂直 in upper, mold is 沿垂直 direction 打开. therefore, its 占 面积 relatively small, easy 安放嵌 parts, mold relatively 方便, material 斗落入 material material can relatively uniform 进行塑化. products ejection rear easy 自动落 lower, must use lower, easy achieve 自动操 as. injection molding machine used for small type injection molding machine, generally is in 60克 below/following injection molding machine using/adopting relatively more, large, in type machine using/adopting.

        (3)角式 injection molding machine: its injection direction and mold separation interface in 同一 面 upper, it especially combined processing in separation 不允许留 has gate 痕迹 平面 products. it 占 面积 ratio injection molding machine small, 但放入 mold inner parts easy 倾斜落 lower. this type of type injection molding machine used for small machine.

        (4) more 模转盘式 injection molding machine: it is types more 工位操 as injection molding machine, its features is clamping plant/unit using/adopting 转盘式 structure, mold 围绕转轴转动. this type of type injection molding machine separation injection plant/unit can force, can shrink short production cycle, improve/increase machine production can force, especially combined cooling type time long or 因安放嵌 parts need relatively more time large amount products production, clamping system large, complex, clamping plant/unit clamping force relatively small, this type of injection molding machine in plastics shoe sole and other products production in relatively more.

         generally injection molding machine injection plant/unit, clamping plant/unit, liquid pressure system and electrical control system and other separation.
