Description

一种四联阀阀体铸件及其模具 技术领域
本发明涉及阀体铸件领域，尤其涉及一种四联阀阀体铸件及其模具。
背景技术
多路阀产品主要用于各类液压泵的配套，广泛应用于各类机械液压系统中。目前国内外水平发展相当，国外产品优势表现在耐磨使用寿命长。目前国内同类铸件精度差，技术含量低，国内高端液压元器件长期依赖进口。
目前多路阀阀体铸件一直存在铸造困难问题，阀体内部流道设计必须符合设计需要，还要能够很好的铸造成功，铸造时主孔断裂，主孔弯曲，直线度大于0.6mm，浇口附近的侧孔断裂变形等问题。
阀体铸件在阀门生产和研发的技术支持上，国内阀门比国外相对落后，很多的产品在技术和创新上已经取得突破性进展。进口高压多路阀产品中四联阀阀体以及五联阀阀体由于表面由无数个曲面构成，而且壁比较薄，制造难度大，原因在于制造铸件的型腔复杂，砂型模具加工难度大，对于这种壁薄的产品的制造技术一直还没取得实质性的突破。国内阀门行业的发展应往高端现代化的方向前行，目前阀体铸件的铸造工艺中，砂芯容易开裂，浇注过程中温度低，容易导致铸件出现气孔缺陷，制成的阀门铸件成品密度不均匀，而且易产生裂缝、应用范围受限。
