摘要： A cam and cam follower apparatus translates linear cam bar movement to perpendicular valve stem actuation in an injection molding system. The cam bars reciprocate up and down on linear bearing rails such that an actuation plate, fitted with a plurality of valve stems, is cycled normal to the direction of the cam bar movement via cam followers traveling within cam slots in the cam bars. The cam slots in the cam bars are profiled such that the cam followers affect the speed and force at which the valve stems travel while at the same time reducing frictional effects and their associated power requirement. The cam followers of the valve stem actuation plate travel in cam slots in the cam bars from a valve stem forward position, to a valve stem retracted position and ultimately, the entire actuation plate may be removed from the cam bars for maintenance via open ended slots in the cam bars.

摘要翻译： 凸轮和凸轮从动装置将线性凸轮杆运动转换成注射成型系统中的垂直阀杆致动。 凸轮杆在直线轴承轨道上往复运动，使得装配有多个阀杆的致动板通过在凸轮杆中的凸轮槽内行进的凸轮从动件垂直于凸轮杆运动的方向循环。 凸轮杆中的凸轮槽被成形，使得凸轮从动件影响阀杆行进的速度和力，同时减少摩擦效应及其相关的功率需求。 阀杆致动板的凸轮从动件在凸轮杆中的凸轮槽中从阀杆向前位置移动到阀杆缩回位置，并且最终可以将整个致动板从凸轮杆移除以通过开口槽进行维护 在凸轮杆上。
