一种适用于PC料的注塑机螺杆
本技术涉及注塑机
,具体涉及一种适用于PC料的注塑机螺杆。
技术介绍
注塑机又名注射成型机或注射机,它是将热塑性塑料或热固性塑料利用塑料成型模具制成各种形状的塑料制品的主要成型设备。注塑机能够加热塑料,并对熔融塑料施加高压,从而使其射出并充满模具型腔。螺杆是注塑机的重要部件,它的作用是对塑料进行输送、压实、熔化、搅拌和施压。所有这些步骤都是通过螺杆在料筒内的旋转来完成的,在螺杆旋转时,塑料对于机筒内壁、螺杆螺槽底面、螺棱推进面以及塑料与塑料之间在都会产生摩擦及相互运动。塑料在料筒内的向前推进就是这种运动组合的结果,而摩擦产生的热量也被吸收用来提高塑料温度及熔化塑料。螺杆的设计结构将直接影响到这些作用的程度。现有的注塑机在加工PC料时,由于注塑机螺杆的结构设计存在不合理的问题,从而导致了PC塑料制品的发黄以及出现黄烟的现象,进而使得PC料的生产质量变低。
