Automobile instrument support injection molding process parameter optimization method

Abstract

The invention discloses an automobile instrument support injection molding process parameter optimization method. According to the method, a fixed mould plate is involved. The method comprises the following steps that firstly, analog simulation of an automobile instrument support injection molding process is made through Moldflow software, and molding process parameters are set, thereby obtaining two quality evaluation indexes of volume shrinkage and warpage of a workpiece; and secondly, the molding process parameters are optimized through experiment method design and grey correlation analysis, simulation analysis on the process parameters is made, and then range and variance analysis on data of a simulation result is made. According to the automobile instrument support injection molding process parameter optimization method provided by the invention, the influence of the molding process parameters on the volume shrinkage and the warpage is researched through the experiment method design method, the process parameters are optimized, the precision and quality of the workpiece are improved by changing the molding process parameters, the method has important guiding significance on actual production, and the series of research results have a reference effect on injection molded parts which are actually produced.

Description

Technical field [0001] The present invention relates to the technical field of automotive instrument brackets, in particular a method of injection molding process parameter optimization process for automotive instrument brackets. Background technique [0002] The parts may have a lot of defects during the injection molding process, and most of these defects are unreasonable by the forming process setting, so in the case of the application of the material, structures, and molds, these problems can be improved by adjusting the molding process parameters. The forming process parameters have multiple, and each parameter is related to each other, each parameter has different degrees of impact on the quality of the parts; [0003] With the continuous development of plastics, the application of plastic parts in the automotive industry is increasingly common. For plastic parts with high precision and quality, it is necessary to study the factors affecting accuracy and quality, which is t...
