电磁炉上盖注塑模具设计

Development of Injection Mold for Induction Cooker Upper Shell

分析了电磁炉上盖塑件的结构工艺特点。为了优化模具结构,减少塑件缺陷,采用Moldflow软件对其进行了最佳浇口位置、填充、翘曲变形等模拟分析。以模拟结果为依据,设计了轮辐式侧浇口注塑模,介绍了模具结构及工作过程。采用此模具结构实现了从注射到塑件落料的半自动化生产模,具结构合理生,产效率较高。

The structural and technological characteristics of the molded part of induction cooker upper shell was analyzed. In order to optimize the mold structure and minimize the defects of the molded part during production, the best gate location, filling and warpage of the molded part were simulated by Moldflow software. Based on the simulation results, the injection mold with spider side gate was designed. The structure and working principle of the mold were introduced. The semi- automatic production can be realized from injection to ejection for the mold. The mold structure is reasonable, and the production efficiency is high.
