| 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。 Function of the injection system: the injection system is one of the most important parts of the injection molding machine, generally there are three main forms: plunger type, screw type and screw pre plastic plunger injection type. At present, the most widely used is screw type. Its function is to heat and plasticize a certain amount of plastic in a specified time in a cycle of injection molding machine, and then inject the molten plastic 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 remains set. 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 |
