一、这种浇注系统的实质: 所谓楔形薄浇口,就是将一定尺寸的楔形薄片,设置在铸件上部(造型位置),用它将液态合金直接引入铸型。这种浇口属于上注式,它与雨淋式有相似之处,即浇口位于铸件的最高处。铁水直接引入型腔,具有压头大,液体金属流程短,降温少,充型快的特点。另外,浇口片上端面积大,下端面积小,带有封闭式的特点,也具有一定的挡渣能力。其实质是顶注缝隙式浇口。二、几个生产实例: 1、C616车床床头箱: 它是车床的关键件。材质HT20～40,毛重
First, the essence of this pouring system: The so-called wedge thin gate, is a certain size of the wedge-shaped sheet, set in the upper part of the casting (modeling location), with which the liquid alloy directly into the mold. This kind of gate belongs to the betting type, which has the similarities with the rain type, that is, the gate is located at the highest point of the casting. Hot metal directly into the cavity, with a large head, liquid metal flow short, less cooling, filling fast characteristics. In addition, the gate area of the upper end, the lower end of the area with a closed-type features, but also has a certain slag capacity. The essence is top-notch gap gate. Second, several production examples: 1, C616 lathe headstock: it is the key components of the lathe. Material HT20 ~ 40, gross weight
