阀盖压铸成型工艺及模具设计
摘要:压铸是一种近终形的成形方法,具有生产效率高、尺寸精度高等特点,在制造业,尤其是规模化产业获得了广泛的应用和迅速的发展。压铸件,尤其是镁、铝、锌合金压铸件,在汽车、通讯等领域获得了广泛的应用。
本设计主要进行了阀盖压铸模的设计。首先,对制件进行了工艺性分析,根据制件有长宽比例相差悬殊的特点,采用了侧浇道。其次,根据锁模力的计算,选择了DAM1113G型卧式压铸机;为了便于破损零部件的更换,采用镶拼式结构,对成型零部件进行了详细的设计计算;模具采用导柱、导套实现导向,采用推杆推出制件。最后,对压铸机及模具的强度进行了校核,且借助AutoCAD和UG、PRO/E三维设计软件绘制了模具的装配图和实体图。

Vibrator switch cover die casting molding process and mold design
Abstract:Die casting is a near-shape of its characteristics of high efficiency and dimensional precision,it is used widely and developed rapidly in manufacturing,especially in mass-produced castings,especially magnesium alloy, aluminum alloy, zinc alloy die castings,are used in various fields,such as automobile munication.
In the paper, a die casting die of Bracket is mainly ,its processing properties are gate runner is used according the characteristics of the analysis of the length and of the width of the ,die casting machine that the type is DAM1113G is design,insert construction is used in order to replace spoiled design and calculation of molding parts are made in mold is guided by guide pillars and ejector pin is used to side-core is drawn by inclined guide ,die casting machine and mold strength are assemble and
