中文摘要:
      为了缩短传统注塑模具的开发周期与制备成本,基于快速原型技术的快速模具逐渐发展了起来。其中光固化快速原型技术可以实现模具型腔从设计到原型的一步成型,对于产品开发初期的小批量生产具有重要意义。根据近年来国内外光固化快速模具的研究现状,笔者分析光固化快速模具与传统模具的主要区别,探讨了光固化模具的导热特性对注塑产品结晶度、收缩率和机械强度的影响,总结了光固化模具的机械特性与模具失效形式的关系以及光固化模具的导热率与机械特性对注塑工艺选择范围的影响。提出光固化模具适合成型中小尺寸的产品,未来将在含有复杂曲面的微注塑中得到广泛应用。
英文摘要:
      In order to shorten the development cycle and preparation cost of traditional injection molds, rapid molds based on rapid prototyping technology have gradually been developed. The light curing rapid prototyping technology can realize the one step molding of the mold cavity from design to prototype, which is of great significance for small batch production in the early stage of product development. According to the research status of light curing rapid molds at home and abroad in recent years, the main differences between light curing rapid molds and traditional molds were investigated, and the effect of thermal conductivity of light curing molds on the crystallinity, shrinkage rate and mechanical strength of injection molded products was reviewed. At the same time, the relationship between the mechanical characteristics and failure modes of the light curing mold was analyzed. The influence of thermal conductivity and mechanical properties of light curing molds on the selection range of injection molding process was concluded. It is suggested that the light curing molds are suitable for molding small and medium sized products, and will be widely used in micro injection molding with complex curved surfaces in the future.
