| 注塑机注射系统 Injection system of injection molding machine 注射系统的作用：注射系统是注塑机最主要的组成部分之一，一般有柱塞式、螺杆式、螺杆预塑柱塞注射式3种主要形式。目前应用最广泛的是螺杆式。其作用是，在注塑料机的一个循环中，能在规定的时间内将一定数量的塑料加热塑化后，在一定的压力和速度下，通过螺杆将熔融塑料注入模具型腔中。注射结束后，对注射到模腔中的熔料保持定型。 The function of injection system: the injection system is one of the most important parts of injection molding machine. There are three main forms of injection system: plunger type, screw type and screw pre molding plunger injection type. At present, the screw type is the most widely used. Its function is that in a cycle of injection molding machine, a certain amount of plastic can be heated and plasticized within a specified time, and the molten plastic is injected into the mold cavity through the screw under a certain pressure and speed. At the end of the injection, the molten material injected into the mold cavity is kept in shape. 注射系统的组成：注射系统由塑化装置和动力传递装置组成。 Composition of injection system: the injection system is composed of plasticizing device and power transmission device. 螺杆式注塑机塑化装置主要由加料装 保定平面设计培训 收费岛模具 挡土墙模具 防撞墙模具 防撞墙模具 防撞护栏模具 大棚遮阳网 遮阴网 置、料筒、螺杆、过胶组件、射嘴部分组成。动力传递装置包括注射油缸、注射座移动油缸以及螺杆驱动装置（熔胶马达）。The plasticizing device of screw injection molding machine is mainly composed of feeding device, barrel, screw, glue passing component and nozzle. The power transmission device includes injection cylinder, injection seat moving cylinder and screw driving device (melt glue motor). |
