| 中文摘要: |
| 为了解决弹用塑料包装箱箱体内部复杂结构不易脱模的问题以及注塑疵病问题， 采用多元件联合脱模机构， 进行了模具的改进以及工艺的匹配调试。通过生产实践表明， 多元联合式脱模设计方案彻底解决了弹用塑料包装箱箱体内部复杂结构不易脱模的问题。通过工装的改进， 解决了搬手部位熔合不好、 熔接痕变深、 近似裂纹的注塑疵病。生产效率大大提高， 确保了复杂产品的质量， 并取得了很好的经济效益。 |
| 英文摘要: |
| To solve the problems that elastic plastic packing box with complex internal structure is not easy to release and the defects of injection molding， the multi element and stripping mechanism was used， the improvement of the mold and the process of the matching and debugging was made. The production practice proved that the multi-combined-type design solution of the shell completely solved the problem of difficulty in demoulding of the complex structure of the box body of the shell. The improvement of tooling solved the problems that wrenching part fusion was not good，the weld line became deep and the crack-like injection molding defect. The production efficiency was greatly improved，the quality of complex products was ensured，and good economic benefits were achieved. |
