工艺参数对溢流法水辅助注射成型中纤维堵塞的影响
Influence of fiber blocking in water-assisted injection molding on overflow process parameters
摘要
Abstract
This study investigates the impact of key process parameters in overflow-type water-assisted injection molding on short glass fiber blockage within the molded part's internal channels.Experimental results reveal that melt temperature in the range of 230～240℃significantly affects fiber blocking behavior.Specifically,increasing the melt temperature from 230 to 240℃shifts the blockage location from the entire main cavity flow path to the distal end of the flow channel.Simi-larly,a water injection delay time of 3～5 s exerts a pronounced influence:extending the delay from 3 s to 5 s causes the blockage zone to migrate from the mid-section of the flow channel toward its proximal half.Additionally,injection pres-sure in the range of 6～8 MPa shows a clear effect,raising the pressure from 6 to 8 MPa relocates the blockage from the latter half of the channel to several discrete segments near the middle.These findings provide valuable insights into con-trolling fiber distribution and mitigating blockage in water-assisted injection molding of fiber-reinforced polymers.关键词
