查询词典 opening die

As the brittleness of low-k material,the traditional wire bonding parameter often lead to die pad crack or Au-AL matter bad;after used low-k material,die size,die pad opening and die pad pitch change to more little,wire change to lengther and density change to more higher,it\' s new challenge for molding and wire bonding;at the same time, low-k material also require to control the thermal stress in package.

由于低介电常数材料的脆性，传统的引线压焊参数设置将会导致焊盘碎裂以及金铝化合物不良；由于使用低介电常数材料后，芯片尺寸、压焊区域和压焊间距进一步减小，金线压焊长度和密度大大增加，这就为压焊和模塑提出了新的要求；同样由于低介电常数材料的应用，对封装体内部的热应力的控制也提出了更高的要求。

The die cast has opening doors and an opening hood.

压铸有开始门和一个第一次的引擎盖。

Die lands should be 3-5 times the dimension of the die opening;entrance angles to the land should be as

模具面积应是模槽尺寸的3-5倍；入口角的度根据特殊情况考虑，尽可能小而实用，但是， 10 °-60 °是常见的。

The occurrence of wrinkling is attributed to the large die gap, which is the difference between the side length of the die cavity opening and the side length of the punch head.

出现的皱折是由于模具间隙大引起的；该间隙在模具腔口的侧面距离和冲头侧面距离之间有差别。

In order to examine the effect of die gap on the wrinkling, the stamping of a tapered square cup with three different die gaps of 20 mm, 30 mm, and 50 mm was simulated. In each simulation, the die cavity opening is fixed at 200 mm, and the cup is drawn to the same height of 100 mm.

为了验证模具间隙对起皱的影响，模拟了一个在从20MM， 30MM和50MM不同模具间隙下的锥形方杯的冲压，在每次仿真中，模腔打开固定在200MM，杯形拉伸同样高度100MM。

Please not that a 250 mm wide die opening will produce a film or sheet with less width since you have a "neck in" effect when you pull out the melted resin from the die before it reaches the surface of the chill roll. the width you can achieve depends on the melt strength of the resin as well as the distance between the die lip opening and the chill roll. but in general, about 80% of the die opening width can be achieved.

注意：250毫米宽开口的模头只能获得小于此宽度的薄膜或片材，因为当熔体树脂被从模头拉至冷辊上时会产生&颈缩&效应，最终获得的实际宽度依赖于树脂的熔体强度以及模唇开口同冷辊之间的距离，但总而言之，可获得模头开口宽度80%的产品宽度。

Film die where the mandrel is equipped with spider fed spiral flow channels for uniform distribution of polymer melt around entire die area. all internal die parts are hard chromed with high polish. easy adjustable die opening for accurate film thickness control.

模头心轴处安装了蛛网供料螺旋导流槽使聚合物熔体在整个模头区域得到均匀一致的分布，所有的模头内部部件均镀硬铬并高度抛光；易于调整的模头开口容易获得准确的薄膜厚度控制。

An improvement on the die casting technology of aluminium hub includes drilling hole at the position of die, where the function of die is not affected, for preventing gas from coming into molten aluminium, mounting safety valve to the exhaust opening of die casting case for keeping proper pressure to save electricity and shorten die casting time, and increasing the water-flowing area of cooling disk or ring for higher cooling effect.

一在不影响模具本身功能部位钻孔增加排气通道，解决了压铸过程中产生的气体进入铝水问题。可使铝轮减少气孔。在压铸机箱体排气口部位，安装安全阀，能使压铸机箱体内保持适当的压力，工作时少进气、少排气，起到节电不堵浇口，缩短压铸时间，提高产量。冷却盘、冷却环改进后，增加了过水面积，提高了冷却效果。
