Description

消失模铸造埋箱型砂缓冲装置
技术领域
本实用新型属于消失模铸造设备,具体涉及一种消失模铸造埋箱型砂缓冲装置。
背景技术
消失模铸造是一种精密、环保、适应性广的新型铸造工艺,是将聚苯乙烯泡沫塑料通过模具成型制成模型,俗称白模,表面涂耐火涂料,烘干后,在抽真空砂箱内用干砂填砂埋箱,浇铸成铸件。在埋箱时由于型砂对白模模型的冲击,使白模变形或涂料破裂,对薄壁易变形件尤为明显。目前解决些问题使用的方法为雨淋加砂和布袋加砂,但由于雨淋加砂器和布袋加砂距模型较高,实际上形成柱状砂流,对白模模型及其表面涂料直接冲刷,仍不能解决变形及裂纹问题。因此,防止埋箱白模变形和涂料破裂是消失模铸造埋箱亟待解决的难题。
发明内容
本实用新型所要解决的技术问题是克服上述不足,提供一种消失模铸造埋箱型砂缓冲装置,该装置使型砂形成均匀的细薄状瀑布砂流,缓解型砂自由落体时的惯性能量,从而解决了埋箱时型砂模型变形和涂料破裂的问题。
本实用新型的技术方案:一种消失模铸造埋箱型砂缓冲装置,它包括砂库、加砂器、连接板、缓冲装置和砂箱,砂库的下端设置有加砂器,加砂器通过连接板与缓冲装置连接,砂箱设置在缓冲装置的下方;所述的缓冲装置是由壳体和条状格栅组成,条状格栅与壳体连接,所述的壳体的材质为钢板,钢板的厚度为3mm,条状格栅是由两层缓冲管排列而成,相邻的缓冲管之间的间隙为5~7mm,所述的缓冲管为直径为20mm的薄壁不锈钢管。
本实用新型与现有技术相比具有以下有益效果:本实用新型缓解型砂自由落体时的惯性能量,使型砂形成均匀的细薄状瀑布砂流,避免了砂流对模型及涂料的直接冲击,从而解决了埋箱时型砂模型变形和涂料破裂的问题。
附图说明
图1是本实用新型的结构示意图;
图2是本实用新型中缓冲装置的结构示意图;
图3是图2的局部放大视图。
具体实施方式
一种消失模铸造埋箱型砂缓冲装置,如图1所示,它包括砂库1、加砂器2、连接板3、缓冲装置4和砂箱5,砂库1的下端设置有加砂器2,加砂器2通过连接板3与缓冲装置4连接,砂箱5设置在缓冲装置4的下方;所述的缓冲装置4是由外壳6和条状格栅7组成,条状格栅7与壳体6连接,所述的壳体6的材质为钢板,钢板的厚度为3mm,条状格栅7是由两层缓冲管8排列而成,相邻的缓冲管8之间的间隙为5mm,所述的缓冲管8为直径为20mm的薄壁不锈钢管。
当型砂落入缓冲装置4的壳体6中,通过缓冲管的缝隙从第一层缓慢绕过第二层,从第二层的缝隙落下,形成细薄状瀑布砂流,缓解了型砂落下的惯性能量,避免了砂流对模型及涂料的冲击。
