往復(fù)螺桿式注塑機(jī)注射系統(tǒng)設(shè)計(jì)
摘要
本文根據(jù)給定的設(shè)計(jì)參數(shù)介紹了一種往復(fù)螺桿式注射系統(tǒng)的設(shè)計(jì)，所設(shè)計(jì)的注射系統(tǒng)包括傳動(dòng)裝置、塑化裝置、注射裝置三大部分。傳動(dòng)裝置采用了單級(jí)齒輪減速器和三相異步電動(dòng)機(jī)滿足設(shè)計(jì)要求，塑化裝置采用了三級(jí)變徑螺桿與料筒結(jié)合完成對(duì)坯料的塑化，注射裝置采用了單向液壓缸與往復(fù)螺桿結(jié)合，由液壓缸活塞推動(dòng)螺桿完成注射過(guò)程并在下一循環(huán)的塑化過(guò)程中自動(dòng)完成螺桿的退回。所設(shè)計(jì)的裝置具有結(jié)構(gòu)簡(jiǎn)單、性能可靠、制造容易的特點(diǎn)。

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
