基于响应面法的汽车接插件翘曲变形优化

为减少汽车接插件在注塑成型过程中出现翘曲变形问题，以某汽车接插件为研究对象，选取模具温度、熔体温度和保压压力为响应面影响因素，以塑件的翘曲变形值为响应目标，运用响应面法Box-Behnken设计试验方案. 利用Design-Expert软件分析试验结果，建立响应面响因素与响应值之间的二阶响应面模型，获得最佳工艺参数组合为:模具温度为50 ℃、熔体温度为280 ℃、保压压力为60 MPa. 试验结果表明，采用该工艺组合生产的注塑件翘曲变形值下降21.26%，符合预期要求.

Warpage optimization of automobile connector based on response surface method

In order to reduce the warp deformation problem in injection molding process of car plug-in, a car plug-in was used as the research object, the mold temperature, solute temperature and pressure-keeping pressure were selected as the response surface influence factors, the warping deformation value of the plastic part was used as the response target, experiment scheme was designed by using the response surface method Box-Behnken. Taking advantage of Design-Expert software, the test results were analyzed, the second-order response surface model between the response surface sound factor and the response value was established, and the best combination of process parameters obtained as follow: mold temperature of 50℃, melt temperature of 280℃, pressure of 60 MPa. The experimental verification results show that the warped deformation value of injection molding parts produced by the process combination decreases by 21.26%, which can meet the expected requirements.
