一、模具制造方法的历史为了了解模具制造方法是怎样发展起来的,为了回忆人们何时首次用手工粗造地制作与挤压件形状相称的样板,用它作为制造模具的规准,回顾一下过去是有益的。过去,凹模底面铣平后,经钻、锯以及再用手工锉加工具洞口,直到样板能与洞口匹配,并且从形状轮廓缝隙透过的光亮均匀一致为止。然后,将模具进行热处理、研磨和手工抛光。这种模具制造方法的劳动强度很大。五十年代中期,有几家制造挤压模具的工厂开始应用一种称为电火花加工或EDM的新工艺。用这种新型机床,把手工制作的样板经热处理后粘贴到一块石墨上,并把它锉成电 First, the history of the mold manufacturing methods In order to understand how the mold manufacturing method developed, in order to recall when people for the first time by hand to make rough and extrusion shape of the template, use it as a mold manufacturing standards, look back The past is useful. In the past, after the bottom surface of the die was milled, the hole was drilled, sawed and re-hand-filled until the template matched the hole and the light transmitted through the gap of the shape was uniform. The mold is then heat treated, ground and hand polished. This method of making molds is labor intensive. In the mid-1950s several factories manufacturing extrusion dies started applying a new process called EDM or EDM. Using this new machine, the hand-made pattern is heat-treated and pasted onto a piece of graphite and filmed into electricity
