摘要:

针对汽车制动灯盖板的结构特点和技术要求,设计了一副热流道大型注塑模具。通过采用一种新型的交叉辅助杆斜顶抽芯结构,成功解决了大角度斜向抽芯脱模难题。通过采用热流道和圆弧潜伏式浇口,提高了塑件尺寸精度和外观质量。通过采用油缸顶出和复位的方式,保证了塑件顶出平衡和模具复位安全可靠。通过采用网格式立体冷却系统,成型周期缩短至35 s,模具的生产效率提高了约8 %。

Abstract:

In this work, we designed a large?scale injection mold with hot runners for the car bremsleuchte cover according to its structural characteristics and technical requirements. The problem in the large angle inclined roof lateral core?pulling process was successfully solved by using a new type of diagonal push rod with a cross assist bar. The accuracy and appearance of plastic parts were improved by using a hot runner and an arc latent gate. The safety and reliability of ejection balance of plastic parts and mold reset were ensured by taking the way of cylinder ejection and reset. The molding cycle was shortened to 35 s, and the production efficiency of the mold was increased by about 8% after adopting a mesh pattern 3D cooling system.

Key words: car bremsleuchte cover, large injection mold, hot runner, diagonal push rod with cross assist bar, mesh pattern and three?dimensional cooling system
