Ultimate Diecast Tooling System 超级压铸模具制造系统


Te plunger of a diecasting machine, moving smoothly with a minimum of lubrication, pushes a measured amount of molten alloy through a round and straight shot sleeve and injects it into the die cavity, where it almost instantly hardens. In that moment, when the liquid alloy is converted into a solid casting, most of the added value, which is the diecaster’s liveli- hood, is generated. Tis is the crux of the diecasting process and may be fairly termed, “Te moment of casting.” At one time, in the quest for increased productivity, the com-


ponent of the diecasting process that had the greatest potential for improvement was the die itself. Not all diecasters realize that in recent years this priority has changed considerably. With the use of three-dimensional computer modeling to predict the ideal flow of metal into the die and ultra-accurate multi-axis CNC machining to produce a die that can consistently make large convoluted castings with inordinately close tolerances, the diecaster should now be able to assume that the dies he is using are likely as good as they need to be. Te best opportunity for improvement now usually lies with the delivery of the alloy into the die. Analyzing the various forces that impact on the moment of casting, the diecaster of today soon will realize that to even approach maximum productivity, the plunger and the shot sleeve must work closely together, since their functions are inseparably combined. Te market for light metal die castings continues to grow. Castings are becoming bigger, more complex, and better in every way. Technology is keeping pace with the changing market, but castings are still made by diecasters, not just by machines, and the diecaster’s basic approach to the produc- tion process is more important than ever. For better diecast- ing, the effectiveness of interacting components should never be considered individually, but always together. Diecasting is a process that can improve only when all parts work together as a system. Experience has proven that always considering the casting process to be a unified system rather than merely a group of disparate components virtually assures increased productivity.—Paul Robbins, CASTOOL Tooling Systems, Uxbridge, ON Canada 


压铸机的柱塞在最小的润滑作用下平滑运动,它 使一定量的合金液通过圆形且笔直的压射缸压送到压 铸金属型(压型)型腔里,合金液在型腔中几乎立即 凝固。当合金液转变成固体的铸件时,附加值的大部 分也就产生了,这就是压铸企业的盈利之道。这一时 间段是压铸工艺的关键所在,当然可以称之为“铸造 的时刻”。


以前,如要求提高生产率,压铸工艺过程中最具 有潜力的因素就是压型本身。但是,近年来,这一趋 势已经发生了很大变化,并不是所有的压铸企业都意 识到了这个问题。使用三维计算机模型来预测金属液 进入压型的理想流程,并通过超精准多轴数控机床生 产压型,能够稳定地生产公差非常严格的大型复杂铸 件,压铸企业现在应认识到所使用的压型几乎与他们 所希望的一样好。现在,改进的最好时机在于如何使 合金液进入压型。通过对影响铸造时各种因素进行分 析,现在的压铸企业将很快认识到,为了达到最大的 生产率,柱塞和压射缸的关联性是极强的,因为它们 的功能是密不可分的。


轻合金压铸的市场在不断扩大。铸件越来越大、 越来越复杂且各方面性能都更好。科技是与市场的变 化保持同步的,但是铸件仍是由压铸作业人员生产的 而并非只靠机器。因此,压铸企业采用的基本生产工 艺比以往更加重要。对于更好的压铸工艺来说,相 关联部件的效率不应分别地考虑,而应该作为一个整 体来考虑。只有当所有的部件作为一个系统整体运 作时,压铸工艺才能得到改进。经验已经证明,事实 上,将铸造工艺过程作为一个系统考虑比仅仅作为多 种组件的群集来考虑更能提高生产率水平。——加 拿大阿克斯布里奇,CASTOOL模具系统公司,保 罗•罗宾斯 
