| 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. |
