床身铸 件浇注系 统正确的引入位置:

机床铸 件控制凝固方法有很多种大型铸件、球墨铸件、机床横梁,但多种 方法全集中在一个机床铸件上下一定就是理想的通常只要根据机床铸件结构采用一项或两项就可以了。

通常有几种控制方法,浇注系 统正确的引入位置。选择内 浇道从机床铸件厚实处引入,则加强 机床铸件定向凝固,确定内 浇道与冒口位置内浇道应尽可能靠近冒口或使金属液经过冒口而进入铸型型腔,以加强凝固倾向。确定内 浇道在铸型不同高度引入有三种引入形式既顶注式、底注式和中间注入式,顶注式 有利于冒口补缩,底注式 快浇注不利于冒口补缩,铸件底部易产生缩孔、缩松、底注式 慢浇更不利冒口补缩,但对易 氧化的合金或型腔较高型腔复杂的机床铸件往往采用底注,主要是 为了金属液流入平稳,避免金属飞溅和氧化,不冲坏铸型或型芯。阶梯式 浇道即可防止合金飞溅和氧化有可获得定向凝固。


There are many kinds of large castings, spheroidal castings and machine tool beams for machine tool casting control solidification methods. However, it is ideal to concentrate all kinds of methods on a machine tool casting. Usually, one or two items can be used according to the machine tool casting structure.

There are usually several control methods for the correct introduction of the gating system. Selecting the sprue from the thick part of the machine tool casting, strengthen the directional solidification of the machine tool casting, determine that the sprue in the gate and the riser position should be as close as possible to the riser or the molten metal enters the mold cavity through the riser, Strengthen the tendency to solidify. It is determined that the inlets are introduced into different heights of the mold and there are three introduction forms: top injection type, bottom injection type and intermediate injection type. The top injection type is favorable for feeder feeding, and the bottom injection type quick casting is not conducive to feeder feeding, casting. The bottom is prone to shrinkage, shrinkage, and low-injection, which is more disadvantageous for feeder feeding. However, for the oxidized alloy or cavity, the machine tool casting with high cavity complexity often uses an underfill, mainly for the smooth flow of molten metal. To avoid metal splashing and oxidation, and not to damage the mold or core. Stepped runners prevent alloy splashing and oxidation from achieving directional solidification.
