Abstract

本实用新型公开了砂箱箱体与箱盖的连接结构,包括箱体和箱盖,在箱体上端口的外凸板上设有与箱盖下端口的外凸板上的螺栓过孔相对的螺栓过孔,螺帽与所述螺栓的螺纹相配。本实用新型与现有技术比较具有劳动强度低和连接牢固可靠的优点。

Description

砂箱箱体与箱盖的连接结构
技术领域:
本实用新型涉及一种铸造砂箱,特别是砂箱箱体与箱盖的连接结构。
背景技术:
铸件是机械中常用的毛坯件,用量很大,铸件在浇铸过程中,由于铁水的重量和其膨胀系数较大,会导致箱盖被顶起,轻者铸件变形而板废,重者铁水溢流引发事故,为避免箱盖上移导致的上述缺陷,现行的措施是在箱盖上放置重物,而重物靠工人的经验,这种方案的缺点是,劳动强度大和效率低。
发明内容:
本实用新型的目的是提供一种劳动强度低、效率高且安全可靠的砂箱箱体与箱盖的连接结构。
实现本实用新型目的的技术方案是,砂箱箱体与箱盖的连接结构,包括箱体和箱盖,其特征在于:在箱体上端口的外凸板上设有与箱盖下端口的外凸板上的螺栓过孔相对的螺栓过孔,螺帽与所述螺栓的螺纹相配。
本实用新型与现有技术比较具有劳动强度低和连接牢固可靠的优点。
附图说明:
图1是本实用新型的结构示意图。
具体实施方式: 
结合上述附图对本实用新型作详细说明,在箱体1上端口的外凸板2设有与箱盖4下端口的外凸板3上的螺钉过孔相对的螺钉过孔,螺栓5穿于上述箱体端口外凸板和箱盖端口外凸板上螺钉过孔,螺帽与此螺栓相配。上述螺栓的数量根据砂箱规格的大小沿箱体的四壁均布多个。
本实用新型的操作方法:在浇注铁水时,首先用螺栓将箱盖固定在箱体的上端后,便可进行浇注铁水,取铸件时首先拧下螺栓的螺帽,去掉螺栓后,即可移开箱盖取出铸件。
