摘　　要：介绍了一种压铸模中使用的滑块反顶机构,并介绍了此滑块反顶机构的原理及详细技术条件。在规定的技术条件下制造的滑块反顶机构实际运行稳定,能有效的解决薄壁类铝合金油底壳由于抽芯滑块包紧力过大,在抽芯滑块开模时引起的压铸件变形问题。通过两个类似结构的铝合金油底壳压铸件对比,证明此滑块反顶机构在防止因滑块抽芯引起的压铸件变形问题上效果显著,优于常规滑块抽芯防变形结构。This paper will have an introduction to a slider anti-pushing mechanism application for a die-casting die and to its principles together with the specific technical conditions.The slider anti-pushing mechanism within the specified technical conditions is stable in actual operation,effectively addressing the deformation issue of thin-wall aluminum oil pan when the core-pulling sliders open the die with strong holding force.Through a contrastive study of two aluminum oil pans in homologous structures,this paper will demonstrate that this mechanism can make a great difference on the deformation issue and it is superior to other common sliders with anti-deformation structures.
