| 中文摘要: |
| 为了解决因现有塑料样条模具采用固定模仁结构，而模座和模仁不能重复使用的缺点，设计了一种可换模仁式
样条注塑模具，以生产不同样条。采用可换式模仁、标准化的顶出系统和冷却系统设计，实现样条注塑模具的可换性和
标准化。结果表明：利用该样条注塑模具，只需更换模仁而不拆卸模具即可生产不同标准和不同类型的测试样条；通过
可拆卸的顶杆固定板能够方便地更换顶针，以适应不同样条的顶出需求，实现顶出系统的标准化；通过固定冷却水管位
置和自锁插头的设计，实现冷却系统的标准化。实际的可换模仁式样条注塑模具达到了使用要求。 |
| 英文摘要: |
| A strip specimen injection mold with alternative mold core was designed to produce different strip specimen
based on the process analysis of plastic strip specimen. Alternativeness and standardization of strip specimen injection
mold were obtained with alternative mold core. standard ejecting system and cooling system. The design results show
that: by using the proposed strip specimen injection mold, strip specimens in different standards and types can be
injected by only changing the mold core without dismounting the mold, ejecting pins can be changed conveniently by
dismounting the pin fixed planet, the standardization of the cooling system was realized by using the fixed cooling pipe
and self-lock plug. The real strip specimen injection mold with alternative mold core satisfies the demand of utilization. |
