塑料模具分型面的選擇

  確保產品的外觀。因為有些塑料零件是用在產品的外觀上,相當于產品的外觀,外觀應該好看,那些不好看的就不能吸引顧客的注意。因此,在選擇分型面時,還應考慮產品的外觀。因此,比較好不要將分型面設置在塑料光亮光滑的外表面或圓弧的拐角處,以免對塑料的外觀質量產生不利影響。減少模具在外表面留下的痕跡。
  Ensure the appearance of the product. Because some plastic parts are used in the appearance of the product, which is equivalent to the appearance of the product. The appearance should be good. Those ugly parts can not attract the attention of customers. Therefore, when choosing the parting surface, the appearance of the product should also be considered. Therefore, it is better not to set the parting surface on the bright and smooth surface of the plastic or the corner of the arc, in order to avoid adverse effects on the appearance quality of the plastic. Reduce the marks left on the outer surface of the die.
  設計模具結構時,盡可能避免模具側抽芯。由于分型面側向抽芯模具結構的選擇會變得復雜,并將直接影響塑料零件的各種尺寸和塑料零件的裝配精度,制造成本會顯著增加,因此只能在無自我約束的情況下使用。即使選擇了抽芯模具,抽芯也應盡可能短。斜拉運動的距離越短,一方面可以減小模板的厚度,減少塑件的尺寸誤差;另一方面,有利于產品脫模。

  When designing the die structure, core pulling at the side of the die should be avoided as far as possible. Because the selection of lateral core-pulling die structure of parting surface will become complex, and will directly affect the various dimensions of plastic parts and the assembly accuracy of plastic parts, the manufacturing cost will increase significantly, so it can only be used without self-restraint. Even if the core-pulling die is selected, the core-pulling should be as short as possible. The shorter the distance of cable-stayed movement, on the one hand, it can reduce the thickness of the template and the size error of the plastic parts; on the other hand, it is conducive to product demoulding.
  一些塑料齒輪或塑料板要求高平行度、同心度和同軸度。除了提高模具的精度,它還與產品的分型面有關。
  Some plastic gears or sheets require high parallelism, concentricity and coaxiality. In addition to improving the accuracy of the die, it is also related to the parting surface of the product.
