摘要
阐述了多孔材料在精密注射成型模具中的应用优势及其工作原理,着重分析了在排气系统、冷却系统、脱模系统、抽真空系统及模内贴标技术中的应用现状,分析指出其强度、孔率、孔径及孔径分布的控制及机械加工性是未来研究的热点和难点,实现低成本、大规模生产是多孔材料的发展趋势。
The rapid development of plastic parts brought new challenges to precision injection mold design. The advantages and working principle of porous materials in precision injection molds were re- viewed in this paper. Currently, porous materials were employed in injection molds as vent system, cooling system, demolding system, vacuum system, and In Mold Labeling （IML） technology. The strength, porosity, pore size and distribution, surface topography control, and machinability constituted the hot topics. Low cost and mass production will be the development trend in the near future.
