摘要
针对偏心轮支架的结构特点和技术要求,设计了一副热流道注塑模具,通过对偏心轮支架进行结构工艺性分析并结合订单数量与工期确定最优模腔数量。采用一模四腔方式,确定了最佳分型面。设计的浇注系统通过Moldflow软件求出最佳浇口位置。采用圆柱头推杆并计算脱模力与推出面积,保证模具复位安全可靠。
According to the structural characteristics and technical requirements of eccentric support,a hot runner injection mold was designed. The optimal number of cavities was determined by analyzing the structural process of eccentric support and combining the order quantity and construction period. Using the first mock exam,the best parting surface is determined by four cavity. The optimal gate position of the gating system is obtained by Moldflow software. The cylinder head push rod is used to calculate the demoulding force and pushing area to ensure the safety and reliability of mold reset.
