摘　　要：通过对注塑件熔接痕形成机理的研究,阐述阀式浇注技术对熔接痕的控制原理,以注射成型某平板为例,将其模具浇注系统的流道设计为热流道,并采用阀式浇注,采用CAE软件对充填过程进行模拟。结果表明,采用阀式浇注技术对控制熔接痕取得了较好的效果。The control principle of valve-injection on weld marks is analyzed based on studying the forming mechanism of weld marks. The runners of mould gating system are designed to hot styles and they are controlled by valves with a injection molding panel as example, and the filling process is simulated by CAE software. The results show that the weld marks are well controlled by this method.
