注射成型机四孔斜排双曲肘合模机构的运动和力学特性分析

Analysis of motional and mechanical characteristics for diagonal four-point double-toggle clamp of injection molding machine

利用机构学的方法对注射成型机四孔斜排肘杆式合模机构进行了运动和力学特性分析。推导出模板行程、油缸行程、速度变化系数、锁模力和增力倍数等参数的计算公式 ,并介绍了初始角和临界角的计算方法 ,为注射成型机合模机构的设计提供了理论依据。

An analysis of motional and mechanical characte ri stics for the diagonal four-point double-toggle clamp is made by the method of mechanics.The formulas for calculating the mold board stroke,the oil cylinder s troke,the speed variation coefficient,the clamping force and force amplification are derived and the direct calculating method for primary angles and critical a ngles is described.The theoretic basis of the clamp unit design is proposed.
