方框式外观件压铸模的改进

Improvement of Die-casting Mold with Box-type Appearance Pieces

针对方框式外观压铸件的原设计方案失败的原因,对该压铸模进行了重新设计。通过分析认为,金属液充型时应尽量减少拐角,避免涡流产生,以及在适当的位置开设溢流槽和排气槽,以改善填充条件,才能提高模具质量。实践证明新模具的工艺性好,铸件质量高。对该类型压铸模的设计与制造有一定的帮助和借鉴作用。

Aiming at the failing reasons for the original design of the die-casting pieces with box-type appearance,the die-casting mold was redesigned.Through the analysis that the liquid metal filling type could minimize the corner to avoid the vortex,and open the overflow tank and exhaust ducts in the appropriate place to improve filling conditions,in order to improve mold quality.Practice has proved that the new mold art is good and the castings also have high quality,which plays a certain role of help and reference in the design and manufacture of the die - casting mold.
