Abstract

轻型车排气管浇注工艺，其特征在于包括以下工艺过程：将浇口的位置从边侧移到排气管中间的管口部位，使铁水从两个管口注入型腔，从而型腔内的气体在上升铁水推动下，分别由两处浇注通道排出，与此同时又及时的调整了芯头的间隙。本发明由于间隙的严密，铁水不外溢，防止封死芯头，既利于排气又减少飞边铁刺，从而解决排气管的气孔产生的根源，提高了产品合格率。

Description

轻型车排气管浇注工艺
技术领域
本发明涉及一种浇注工艺装备，特别表现在灰铸铁件和球磨铸铁件的生产工艺中，轻型车排气管浇注工艺。
背景技术
在目前的铸造生产中首先根据技术资料要求设计，包括浇口冒口为一体的金属型，并用该型具制做需要电加热覆膜砂，才能完成的砂壳，砂芯制品。
各种半成品铸件砂型需要经过人工组壳，合芯等程序完成浇注前的成品砂型制品。因此工艺生产出的产品需要投入大量的工时，原料及电费，生产效率低，成品率低，打磨也麻烦，工时消耗多。
发明内容
本发明的目的就是为克服上述现有技术存在问题与不足，而提供一种轻型车排气管浇注工艺。
采用的技术方案是：
轻型车排气管浇注工艺，其特征在于包括以下工艺过程：
将浇口的位置从边侧移到排气管中间的管口部位，使铁水从两个管口注入型腔，从而型腔内的气体在上升铁水推动下，分别由两处浇注通道排出，与此同时又及时的调整了芯头的间隙。
本发明由于间隙的严密，铁水不外溢，防止封死芯头，即利于排气又减少飞边铁刺，从而解决排气管的气孔产生的根源，提高了产品合格率。
具体实施方式
轻型车排气管浇注工艺，其特征在于包括以下工艺过程：
将浇口的位置从边侧移到排气管中间的管口部位，使铁水从两个管口注入型腔，从而型腔内的气体在上升铁水推动下，分别由两处浇注通道排出，与此同时又及时的调整了芯头的间隙。
