介绍精密注射塑料成型模具设计中应注意的事项,分析其原因,并提出相应解决方法。精密注射成型要求制品不仅具有较高的尺寸精度、较低的翘曲变形,而且还应有优异的光学性能等。注射成型是最重要的塑料成型方法之一,如何提高注射成型技术水平,生产出高精度的塑料制品,创造附加值高的产品,模具的设计是重要环节。在精密注射成型设计中,除了应考虑一般模具设计事项外,还要特别考虑成型收缩率误差、成型变形、脱模变形。
This article introduces the precautions that should be paid attention to in the design of precision injection plastic molds, analyzes the reasons and puts forward corresponding solutions. Precision injection molding products require not only high dimensional accuracy, low warp deformation, but also should have excellent optical properties. Injection molding is one of the most important plastic molding methods. How to improve the technical level of injection molding, to produce high-precision plastic products, and to create high added value products, is an important part of the design of the mold. In the precision injection molding design, in addition to considering the general mold design issues, but also special considerations molding shrinkage error, forming deformation, demoulding deformation.
