摘要
分析了PP包装盒结构特点,介绍了包装盒底注射模结构设计过程,包括浇注系统、冷却系统以及强脱模结构等。经过试模及生产证明:该模具结构设计合理,成型塑件壁厚均匀、无变形等缺陷,能达到自动脱模的目的,提高了成型效率。
This paper analyzed the structural characteristics of PP packaging box,introducedthe structure design process of its injection mold,that including gating system,cooling systemand strong demoulding structure.Trial and production has proved that the mold has a reasonablestructure design,molding plastic parts have uniform wall thickness,no deformation and otherdefects,it can achieve the purpose of automatic demoulding.The molding efficiency is improved.
