摘　　要：介绍了如何从模具的角度来缩短成型周期的方法,为了缩短开闭模时间滑块的抽芯采用油缸和斜导柱并用的形式;为了缩短注射及保压时间,优化浇口的位置,全处筋条采用镶件的形式并加强排气使得塑料易于充填;为了缩短冷却时间,采用灵活多样的水路形式尽可能多的设置水路;为了缩短塑件的推出及取出时间,采用推块、矩形推杆等形式合理排布其位置并在其上开设油槽使其动作顺畅。经生产验证,生产效率得到提高且量产稳定,可作为同类型塑件短成型周期的结构参考。This paper introduced how to shorten the molding cycle from the design of the mold.In order to shorten the time for opening and closing the injection machine,the slider is moved by a cylinder and angle pins.In order to shorten the injecton time and holding time,the position of the gate should be optimized and the inserts were set to the ribs to help exhaustion so that the plastic is easy to be filled.In order to shorten the cooling time,adopt multiple kinds of cooling patterns to set cooling lines as much as possible.In order to shorten the time for ejecting and taking the product,the product was ejected by ejector blocks and rectangle pins and their positions were be arranged reasonably.And the blocks and pins were setted on oil groove to move smoothly.The actual production verified that productivity has risen greatly with very sable quality,which could provide reference for similar plastics to shorten the molding cycle.
