摘要
本文根据给定的设计参数介绍了一种往复螺杆式注射系统的设计，所设计的注射系统包括传动装置、塑化装置、注射装置三大部分。传动装置采用了单级齿轮减速器和三相异步电动机满足设计要求，塑化装置采用了三级变径螺杆与料筒结合完成对坯料的塑化，注射装置采用了单向液压缸与往复螺杆结合，由液压缸活塞推动螺杆完成注射过程并在下一循环的塑化过程中自动完成螺杆的退回。所设计的装置具有结构简单、性能可靠、制造容易的特点。关键词：注塑机；注射系统；往复螺杆式
Design of The Injection System of Reciprocating Screw Type Plastic Injection Machine
Abstract
The design according to the given design parameters describes a reciprocating screw injection system design, the design of the injection system includes gear, plastics unit, injection unit of three parts. Transmission using a single-stage gear reducer and the three-phase induction motor to meet the design requirements, plasticizing device uses three adjustable screw and barrel combined with the completion of the blank plastics, injection device using one-way hydraulic cylinder and reciprocating Screw combination of hydraulic cylinder piston driven by the injection screw to complete the process and in the course of the next cycle of the plasticizing screw back automatically.The design of the device has a simple structure, reliable performance, easy to manufacture characteristics.Keywords: injection molding machine; injection system; reciprocating screw
