是真空压铸模!挺不错的哦!
挺不错的哦!请问斑竹,应该不是真空压铸模吧!
1. 真空压铸模应该要有很好的气密性,在两旁不会开排气的,否则达不到抽真空
的目的。
2. 这种排气镶块我也设计过,请问用热处理吗?如何冷却?当溢流槽把排气块卡死时如何解决(我们设计的为90度,出现卡死的问题),角度与间隙为几何?
望不吝赐教!!!谢谢<img src="attachments/dvbbs/2003-11/2003112322554619469.jpg" border="0" onload="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onmouseover="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.style.cursor=\'hand\'; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onclick="if(!this.resized) {return true;} else {window.open(\'attachments/dvbbs/2003-11/2003112322554619469.jpg\');}" onmousewheel="return imgzoom(this);" alt="" /> |
