本发明涉及一种铸件浇注系统，具体涉及一种用于机床灰铸铁件成型浇注系统。
背景技术
浇注系统是砂型中引导金属液进入型腔的通道。成功的浇注工艺取决于金属本身的性质、铸型的性质和浇注系统的结构。因此浇注系统的结构对于铸件的质量十分重要。好的浇注系统需要。引导金属液平稳、连续地充型，避免紊流而造成夹卷空气、产生金属氧化物夹杂和冲刷型腔；充型过程中流动的方向和速度可以控制，保证铸件轮廓清晰、完整；在合适的时间内充满型腔，避免形成夹砂、冷隔、皱皮等缺陷；具有挡渣、溢渣能力，净化金属液；浇注系统结构应当简单、可靠，减少金属液消耗，便于清理。
一般的铸件浇注系统由以下4部分构成：外浇口、直浇道、横浇道、内浇道。基于生产线大量的生产实践以及理论研究表明，用于机床灰铸铁件成型浇注系统的内浇道采用陶瓷管能有效地避渣挡渣和减少缓冲，平衡对称的开放式浇注系统能够有效降低金属液在型腔中的压力，防止金属液喷射及避免金属液高速冲刷型腔形成砂眼。因此设计合适的用于机床灰铸铁件成型浇注系统，提高机床灰铸铁件质量是十分重要。
