1.制件 PE-HD胶水瓶头是旋拧在PE-HD瓶上的,被设计成滴管形状。还有一个PE-HD外盖旋拧在瓶头上,进行密封(图1)。 2.模具模具图如图2所示,固定型芯9成形塑件的内轮廓,螺纹型芯齿轮套10由传动齿轮20驱动。螺纹型芯10由螺纹套12导向,该螺纹套齿轮的螺距与瓶头内部的螺纹螺距相同。齿轮20安装在一个大的螺纹铜套21上,它上面装有两个锥形滚柱轴承19,便于旋转。全部机构装在动模部分内,钢质芯轴17旋在铜套
1. Parts PE-HD glue bottle head is screwed on the PE-HD bottle, is designed to dropper shape. There is also a PE-HD cover screwed on the bottle head, sealed (Figure 1). 2 die mold shown in Figure 2, the fixed core 9 forming the inner contour of plastic parts, threaded core gear sleeve 10 driven by the drive gear 20. The threaded core 10 is guided by a threaded sleeve 12 which has the same pitch as the thread pitch inside the bottle head. Gear 20 is mounted on a large threaded sleeve 21 having two tapered roller bearings 19 mounted thereon for rotation. All agencies installed in the dynamic mode part, the steel mandrel 17 spin on the copper sleeve
