塑料模具的加工速度有什么要求

  為什么加工速度在注塑成型中非常重要,因為它不僅關系到零件的加工周期,還決定著加工的經濟成本。我們常說電火花加工速度(EDM machining speed)是指在一定脈沖參數下,在同一單位時間內被蝕刻掉的一定質量和體積的工件,這可以分別用體積加工速度或質量加工速度來表示。
  Why is the processing speed very important in injection molding, because it not only relates to the processing cycle of parts, but also determines the economic cost of processing. We often say that EDM machining speed refers to a certain mass and volume of workpiece etched in the same unit time under certain pulse parameters, which can be expressed by volume processing speed or mass processing speed respectively.
  在表面粗糙度相同的模具鋼上,電極丟失時相對電脈沖產生的比較大加工速度是衡量電脈沖加工和機床加工性能的重要指標。通常狀況下的加工廠得出的是較大擠壓成型交流電,在比較好擠壓成型情況下能夠超過的比較大的擠壓成型速率。因而在人們具體擠壓成型時,因為被零件加工規格與樣子的千姿百態,加工條件和排屑條件不同于理想條件。即使在加工進行粗加工時,加工速度通常也遠低于機床的比較大加工速度指標。
  On die steels with the same surface roughness, the maximum processing speed of relative electric pulse when electrodes are lost is an important index to measure the processing performance of electric pulse machining and machine tools. Usually, the processing plants get a larger AC extrusion forming, which can exceed the maximum extrusion forming rate under the best extrusion forming conditions. Therefore, in extrusion moulding, the processing conditions and chip removal conditions are different from the ideal conditions because of the various processing specifications and shapes of the parts. Even when roughing is carried out in a machining center, the processing speed is usually much lower than the maximum processing speed of a machine tool.

  每一注塑加工脈寬蓄電池充電的當時都是在鋼件表層留有1個細微的凹痕,凹痕的尺寸、蝕除材質的幾個與脈寬動能相似性正相關關聯,即脈寬動能越大,傳送給鋼件上的卡路里就會越大,被蝕除的材質也越大。從方法論上講得話激光焊成型擠壓成型速率正比于單獨脈寬動能和蓄電池充電頻率,但在具體擠壓成型中,單獨脈寬的功效沒有獨立反映的,只是好幾個脈寬相互功效的結果,脈沖電源是接連不斷地以脈寬情況向擠壓成型空隙運輸動能,其流程就繁雜得多,擠壓成型速率是和脈寬蓄電池充電時間、脈寬間距、脈寬蓄電池充電交流電、脈寬波型、擠壓成型成員變量特性、電極材料、銑面標準等相關的多樣化涵數。
  At the time of charging for each injection-moulded pulse-width battery, there is a tiny dent on the surface of the steel. The size of the dent and the material of the etched material are positively correlated with the similarity of the pulse-width kinetic energy. That is, the larger the pulse-width kinetic energy is, the larger the calories transmitted to the steel parts will be, and the larger the material of the etched part will be. From the methodological point of view, the extrusion forming rate of laser welding is proportional to the pulse width kinetic energy and battery charging frequency, but in the specific extrusion forming, the effect of the pulse width alone is not independently reflected, but the result of the mutual effect of several pulse widths. The pulse power supply is continuously transporting kinetic energy to the extrusion forming gap with the pulse width, and its process is much more complicated. Type I rate is a variety of connotations related to charging time, pulse width spacing, AC charging, pulse width wave type, variable characteristics of extrusion forming members, electrode materials, milling surface standards and so on.
  擠壓成型速率在磨具注塑加工中非常關鍵。由于它是塑膠產品出樣的必要條件。假如顧客規定品質好一點的基本上再提早交樣得話,擠壓成型時間和速率是比較關鍵的。
  Extrusion forming rate is very important in abrasive injection processing. Because it is a necessary condition for plastic products to be produced. If the customer stipulates that the quality is better and the sample is delivered earlier, the extrusion forming time and rate are the most critical.
