塑料模具分型面的选择

来源:    发布时间:2019-05-07 14:50:15    点击:

  确保产品的外观。因为有些塑料零件是用在产品的外观上,相当于产品的外观,外观应该好看,那些不好看的就不能吸引顾客的注意。因此,在选择分型面时,还应考虑产品的外观。因此,比较好不要将分型面设置在塑料光亮光滑的外表面或圆弧的拐角处,以免对塑料的外观质量产生不利影响。减少模具在外表面留下的痕迹。
  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.
  设计模具结构时,尽可能避免模具侧抽芯。由于分型面侧向抽芯模具结构的选择会变得复杂,并将直接影响塑料零件的各种尺寸和塑料零件的装配精度,制造成本会显著增加,因此只能在无自我约束的情况下使用。即使选择了抽芯模具,抽芯也应尽可能短。斜拉运动的距离越短,一方面可以减小模板的厚度,减少塑件的尺寸误差;另一方面,有利于产品脱模。

  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.
  一些塑料齿轮或塑料板要求高平行度、同心度和同轴度。除了提高模具的精度,它还与产品的分型面有关。
  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.
