斜度头洗发液瓶盖脱模机构及模具设计
|
摘要
针对带斜度头洗发液异形瓶盖外形不规则、多种形状特征需不同脱模方式的特点,设计了一模二腔的模具结构,结合塑件不同部位脱模情况设计了不同的脱模机构,如在型腔侧采用前模斜顶斜螺纹嘴内孔脱模机构、哈弗滑块同步抽芯脱模机构完成塑件的型腔面脱模;在型芯侧设计了齿轮传动内螺纹脱螺纹机构、型芯块同步推出强制脱模机构;模架采用将标准模架改装成的六板式无顶出结构模架,依靠弹簧+模板顶出方式将塑件完全顶出并使用机械手取塑件及流道废料。实践证明,模具结构新颖,为同类塑件的注塑模具设计提供了有益参考。
Aimed at the characteristics of the shampoo bottle head cover shaped with different irregular features and needed various demoulding ways to finish the molding,a mould structure with two cavities was designed,different demoulding mechanisms were designed for different parts of plastic parts. For example,on the cavity side,the front mould oblique roof and oblique thread mouth hole ejection mechanism were applied,a half slider synchronization core extrating mechanism was used to complete the cavity surface demooulding for the plastic parts,on the core side,the gear transmission screw thread demoulding mechanism and a forced demoulding mechanism of core block synchronous were gived. The standard mold was converted into a mold six slab mold with no ejection mechanism,and also,spring + template ejection method was used to completely eject the plastic out and meanwhile mechanical hand was used to pick out the plastic parts and runner waste. Practice had proved that the structure of the mold had been novel,injection mold design would provided a useful reference for similar plastic parts.
