Abstract

一种免放过滤网的低压铸造升液管，升液管（1）的底部设有进液孔（2），进液孔与升液管内部连通，进液孔的入口面积为升液管流通面积的10-60％。该升液管使低压铸造生产中免放过滤网，降低了全自动化的低压铸造生产线的成本和故障率，处理浇口料头方便，使回炉料增铁更少。

Description

一种免放过滤网的低压铸造升液管 技术领域
本发明属于轻合金低压铸造技术领域。
背景技术
在低压铸造生产中一般在进水浇口处放置过滤网，对小批量生产不算大问题，对大批量连续生产尤其是想实现全自动化时问题就严重了，需要增加自动调整过滤网在空间的方位系统、把过滤网准确连续的推送到固定位置、把过滤网拿起来并安放到进水口处的机械手，这为全自动生产线安排、布置、调试带来很多麻烦，如若能将它取消会大大降低全自动生产线的故障率及成本。有鉴于此，有必要发明一种解决上述问题的用于免放过滤网的低压铸造升液管。
发明内容
本发明为解决上述技术问题，提供了一种免放过滤网的低压铸造升液管，在该升液管的底部设有进液孔，所述进液孔与升液管内部连通，所述进液孔的入口面积为升液管流通面积的10~60%。
进一步的，所述进液孔的开口朝向下方。
进一步的，所述进液孔设于升液管的侧壁上，其开口设于升液管侧壁与底部连接的位置上，并且该开口朝向侧面。
进一步的，所述进液孔的壁厚为3-40mm。
本发明使低压铸造生产中免放过滤网，处理浇口料头方便，使回炉料增铁更少。
附图说明
下面参照附图结合实施例对本发明作进一步的说明。
图1是本发明的结构示意图一；
图2是本发明的结构示意图二。
具体实施方式
请参阅图1和2，是免放过滤网的低压铸造升液管1，在该升液管1的底部设有进液孔2，所述进液孔2与升液管1内部连通，所述进液孔2的入口面积为升液管1流通面积的10-60%。
如图1，所述进液孔2的开口朝向下方。如图2，所述进液孔2设于升液管1的侧壁上，其开口设于升液管1侧壁与底部连接的位置上，并且该开口朝向侧面。所述进液孔2的壁厚为3-40mm。本发明使低压铸造生产中免放过滤网，大大降低全自动化的低压铸造生产线的成本和故障率，处理浇口料头方便，使回炉料增铁更少。
上面结合附图对本发明进行了示例性描述，显然本发明具体实现并不受上述方式的限制，只要采用了本发明的方法构思和技术方案进行的各种非实质性的改进，或未经改进将本发明的构思和技术方案直接应用于其它场合的，均在本发明的保护范围之内。
工业实用性
本发明提供一种免放过滤网的低压铸造升液管 ，在工业大批量生产的过程中能够降低成本以及故障率，方便操作，经济效益高。
