摘要:

根据汽车右后门板的结构特点,设计了一副大型薄壁顺序阀控制的热流道注塑模具。通过前期的模流分析,确定了先进合理的模具浇注系统。通过采用“斜顶+斜顶杆”与“油缸+T形块+滑块”的侧向抽芯结构,成功解决了塑件内外倒扣多、脱模困难的难题。通过采用“直通式水管+隔片式冷却水井”近乎“随形水路”的温度控制系统,模具成型周期下降了约10 %。模具第一次试模成功,结果表明,成型塑件精度达到了设计要求。

Abstract:

In this work, we designed a large and thin?walled injection mold with a sequential valve hot runner. The advanced and reasonable mold gating system was determined using the analysis of mold flow. The difficult problem from demolding plastic parts was successfully solved using a side core?pulling structure with a configuration of ′inclined top+inclined top rod′ and ′oil cylinder+shovel base+slider′. The labor productivity increased by about 10 % by using the conformal cooling channels. The first shoot was successful and the precision of the plastic parts met the requirements of mold design.

Key words: car right?tuer hinten, large and thin?walled injection mold, sequential valve hot runner, mode flow analysis, side core?pulling mechanism, conformal cooling channel
