摘要
"双碳"目标下,气辅成型技术为塑料成型实现降低碳排放提供了有效途径.为精准规划气辅成型参数,提升气辅成型质量和效率,有效降低碳排放,采用三维数值模拟和成型实验,研究参数交互作用下气辅成型工艺正交优化.结果表明,参数交互作用对气体穿透长度影响小,而对气指缺陷的影响显著.极差分析的基础上,获得了优选参数组:熔体温度240℃,注气压力3 MPa,延迟时间4 s,模具温度40℃.经数值模拟和成型实验验证,优选参数组下得到气辅塑件的气体穿透长度及气指指标优良,可用于气辅成型实际生产.
Abstract
Based on the dual-carbon goal,the gas-assisted molding technology can provide an effective way for plastic mold-ing to reduce carbon emissions.To design the gas-assisted molding parameters accurately,improve the gas-assisted molding quality and efficiency,and reduce carbon emissions effectively,the orthogonal optimization with a parameter interaction was studied through 3D numerical simulation and experiments.The results indicated that the parameter interaction had little ef-fect on the gas penetration length but a significant effect on the gas finger defect.Based on the range analysis,the optimized parameter group was obtained at a polymer temperature of 240℃,a gas injection pressure of 3 MPa,a delay time of 4 s,and a mold temperature of 40℃.The numerical simulation and experiments indicated that the gas penetration length and gas fin-ger under the optimized parameter group were excellent,which could be used in the actual gas-assisted molding production.
