On Deformation of the Injection Mold Core

摘要：

For injection mold with core,during the injection molding process,the pressure on the coreis usually uneven and will cause the core to deform.In this paper,on the basis of some predigestionsand assumptions of the model,formulas for forecasting the deformation of the circular cross-sectionand the rectangular cross-section cores under three different injection ways are analyzed.Thetheoretical analysis results of a core with special section are validated through finite element software.At the end,some suggestions are given to minish the core deformation when the calculation value istoo large.
