摘要
在传统斜排五点双曲肘机构的理论基础上,通过机构运动参数分析、理论推导,建立数学模型,得到一套适用于精密全电动注塑机的斜排五点双曲肘机构的理论设计计算方法。针对高速注塑工况,建立了350 t全电动注塑机锁模单元数值仿真模型并进行迭代求解;对机构动模板后退行程曲线、动模板与十字头速度比值曲线、动模板加速度曲线和行程放大比进行分析,得到了评价和控制锁模单元开、合模平稳性和结构紧凑性的方法。
Based on the theory of traditional diagonal five-point double-toggle clamping unit,a set of theoretical design and calculation method of diagonal five-point double-toggle clamping unit suitable for precision in all electric injection molding machine is obtained through the analysis and derivation of mechanism motion parameters and the establishment of mathematical model.The numerical simulation model of the clamping mechanism of 350 ton all electric injection molding machine is established and solved.The key indexes of the mechanism motion are analyzed,and the methods of evaluating and controlling the opening and closing stationarity and structural compactness of the clamping unit are obtained.
