Abstract

The invention discloses a parametric analysis method of effect of an injection molding process to plastic part buckling deformation and aims to solve the technical problem that the prior parametric analysis method of plastic part buckling deformation is low in efficiency. The technical scheme is that the parametric analysis method of effect of the injection molding process to plastic part buckling deformation comprises of first, conducting secondary development to a commercialize mold flow analysis software MoldFlow to achieve parametric calculation and background execution of injection molding numerical modeling; then embedding MoldFlow secondary development procedures into an open-type multidisciplinary parametric analysis and optimization design platform BOSS Quattro, and automatically modifying process parameters according to a BOSS Quattro parametric analysis module and invoking the MoldFlow secondary development procedures to calculate plastic part buckling deformation; and last, acquiring plastic part buckling deformation under conditions of different process parameter values after automatically modifying and calculating the plastic part buckling deformation for several times. Analysis results of the parametric analysis method of effect of the injection molding process to plastic part buckling deformation provides variation tendencies of buckling deformation within each parameter value range, and provides the basis for arrangement of process parameters in the practical production. The whole analysis process is automatically finished, human input is reduced and analysis efficiency is improved.

Description

technical field [0001] The invention relates to a parametric analysis method for the warping deformation of a plastic part, in particular to a parametric analysis method for the influence of an injection molding process on the warping deformation of a plastic part. Background technique [0002] Warpage is one of the common defects of injection molded plastic products, which seriously affects the quality of products. There are many factors affecting warping deformation, including mold structure, plastic part material, molding process parameters, etc. In the actual molding process, when the plastic part material and mold structure are determined, the molding process parameters become the main factors affecting warping deformation. Reasonable analysis of the influence of various process parameters on the warping deformation of plastic parts in the molding process, and obtaining the influence law of process parameters on warping deformation can provide the necessary reference f...
