塑料制品真空注射成型工艺技术研究

Research on Vacuum Injection Molding Technology of Plastic Products

为提升塑料制品在注射成型生产中的质量,拓展塑料制品应用朝大型化精密化方向发展,分析总结了当前真空注射成型技术的应用现状,阐述了真空注射工艺的核心技术问题,在此基础上开发设计出了一种具有自主知识产权,可在普通注塑机上实施真空注射工艺生产的抽真空工艺装备,解决了常规真空注射生产时真空阀容易堵塞、抽真空效果不明显等生产问题,降低了生产制造成本,实现了真空注射成型的稳定生产。

In order to improve the quality of plastic products in injection molding production and expand the application of plastic products to the direction of large-scale precision development.This paper analyzes and summarizes the current application status of vacuum injection molding technology,based on this,a kind of vacuum process equipment with independent intellectual property right is developed and designed,which can be used in the production of vacuum injection molding on the common injection machine,the invention solves the problems such as the vacuum valve is easy to jam and the vacuum effect is not obvious in the conventional vacuum injection molding production,reduces the production cost,and realizes the stable production of the vacuum injection molding.
