摘　　要：对中空保持架进行了结构分析,获得了模具设计难点。针对设计难点并结合生产实际初步设计了模具水路,将冷却水路设计成正交结构,并进行了模流分析。模流分析结果表明定模水路能较好传导热量;动模区域,热量没有很好的传导至水路区域,冷却水路需进一步优化。将制品最大投影面垂直于Z轴放置,沿制品突变处抽取分型线,得定模成型区及动模成型区。为了降低定模仁制造难度,将部分曲面特征用定模滑块、斜导柱机构成型,同时也有利于定模部分排气;对制品的部分倒扣特征,设计定模斜抽-动模斜顶抽芯机构,有效缩小了模具外形结构,使模具结构更加紧凑。针对中空制品内部所有方向都不能设置自动抽芯的难点,设置整体镶拼抽芯机构;对口部倒扣特征,设置斜顶抽芯机构,倒扣成型件选用铍铜材质,保证了动定模的冷却均衡;设计导热铍铜及法向导热片将集聚在制品内部的热量传导至整个动模,提高了动模冷却水路的冷却效果,并通过结构设计增加了模具的排气性能,避免了制品的局部烧焦。The structure of the hollow cage was analyzed and the difficulty of mold design was obtained.According to the design difficulties and production practice,the mold water channel was designed,the cooling water channel was designed as orthogonal structure,and the mold flow analysis was carried out.The results of mold flow analysis show that the fixed mold water channel can conduct heat well.In the dynamic mode area,heat is not well transmitted to the waterway area,and the cooling waterway needs to be further optimized.The maximum projection plane of the product is placed perpendicular to the Z axis,and the parting line is extracted along the mutation of the product to obtain the fixed mold forming area and the dynamic mold forming area.In order to reduce the difficulty of manufacturing the fixed mould,some surface features are formed by the fixed mould sliding block and inclined guide post mechanism,which is also conducive to the exhaust of the fixed mould part.The core pulling mechanism of fixed die oblique pull-moving die oblique top is designed to reduce the shape structure of the die effectively and make the structure of the die more compact.In view of the difficulty that automatic core-pulling cannot be set in all directions in the interior of hollow products,the whole insert core-pulling mechanism is set up.The reverse buckle feature of the mouth,the inclined top core pulling mechanism is set,and the reverse buckle forming part is made of beryllium copper to ensure the cooling balance of the dynamic fixed die.The design of thermal beryllium copper and normal heat conductive sheet will transfer the heat gathered inside the product to the whole moving mold,improve the cooling effect of the cooling water of the moving mold,and increase the exhaust performance of the mold through the structural design to avoid the local burning of the product.
