摘要:

为探究插座上下盖的最佳注塑工艺条件,使用Moldex3D软件对3种不同的进胶方案进行仿真,最终确定潜伏式四点进胶为最佳方案。后续采用正交试验法探究该方案下的最佳注塑成型工艺,结果表明影响塑件翘曲大小的因素,从大到小依次为保压时间>熔体温度>模具温度>保压压力,最佳工艺参数为熔体温度200 ℃、模具温度45 ℃、保压时间25 s、保压压力55 %。经过模拟验证,优化后的翘曲最大值为0.863 mm,相较于初始工艺条件降低了0.574 mm,优化了近40 %,有效提高了产品质量。

Abstract:

To investigate the optimum injection molding process conditions for the upper and lower covers of a socket, the Moldex3D software was used to simulate and compare three different feeding schemes. The latent four⁃point gluing was finally determined to be the best scheme. Subsequently, an orthogonal test method was used to explore the optimal injection molding process under this scheme. The results indicated that the factors affecting the warpage of the plastic parts was followed by an order of holding time>melt temperature>mold temperature>holding pressure. The optimum process parameters were determined to be a melt temperature of 200 ℃, a mold temperature of 45 ℃, a holding time of 25 s, a holding pressure of 55 %. After simulation verification, the maximum warpage value after optimization was determined to be 0.863 mm, which increased by 0.574 mm compared to that obtained under the initial process conditions. This result was optimized by nearly 40 %, and the product quality was effectively improved.
