清纱器导光件注射模设计

Design of injection mould for light guiding part of yarn clearer

针对导光件在试生产时存在导光效果差、导光柱中有气泡等缺陷,提出新的设计方法,通过弹簧侧向分型、斜导柱内侧抽芯,采用阶梯分型面,成功地解决了导光件在试生产阶段存在的缺陷,保证了产品质量,降低了生产成本,提高了生产效率。

In view of defects existing in an injection molding light guiding part that has poor light-guiding effect and gas cavities; a new design method was proposed in which some structures were adopted, such as side parting by spring, inward core-pulling by angle pin and step-shaped parting surface. The technique can eliminate the products defects, upgrade the quality, reduce costs and raise production efficiency.
