在压铸行业中,特别是生产铝合金铸件,对如何延长模具寿命,一直是个难题.模具寿命不长,主要反映在型腔表面早期龟裂和型腔型芯受到高速金属流的冲击,经常发生粘模,造成严重磨损。本文介绍了用碳化钨强化的方法,对延长模具使用寿命,确有效果。该设备比较简单,花钱不多,文中附有具体线路,可供参考。 In the die-casting industry, especially the production of aluminum alloy castings, it has been a dilemma on how to prolong the die life.The die life is not long, mainly due to the early cracking of the cavity surface and the impact of the cavity core by the high-speed metal flow, which often occurs Sticky mold, causing severe wear. This article describes the method of strengthening with tungsten carbide, to extend the service life of the mold, indeed effective. The device is relatively simple, not much money, the paper with specific lines for reference.
