动模滑块侧向抽芯机构的改进设计

Improved design of the side slide core-pulling mechanism on the moving mould

分析了塑件外观面上夹线的成因,指出了传统的动模滑块侧向抽芯机构设计所存在的不足,提出了带定位锁结构的滑块改进设计方案,并对其工作原理、设计与制造中的注意事项进行了说明。模具企业的生产实践证明,新的设计方案对提高塑件外观表面质量效果显著。

Based on analyzing the cause of the parting line on the surface of the plastic part, the shortcomings of traditional design of the side slide core-pulling mechanism was pointed out. As a result, the improved design plan of the slider with locating lock, whose operational principle and instructions of design and manufacturing was illustrated in the article, came up. According to the productive practice in mould manufacturing enterprises, the new design has a remarkable effect on improving the quality of surface on the plastic part.
