Description

压铸合金的流动性测试模具Flow test mold for die casting alloys

技术领域technical field

本发明涉及铸造测试模具技术领域,尤其涉及一种压铸合金的流动性测试模具。The invention relates to the technical field of casting test molds, in particular to a fluidity test mold for die-casting alloys.

背景技术Background technique

压铸作为一种快速的近净成型工艺,具有生产效率高、尺寸精度高、力学性能优异、可以成型形状复杂和轮廓清晰的薄壁深腔铸件等特点。为了获得优质集成化的大型、复杂、薄壁汽车铝合金压铸件,研究薄壁铝合金件压铸充型流动行为成为此类零件成型的基本问题,因为其不仅直接关系到零件是否能完整成型,同时也影响铸件最终的组织力学性能。As a fast near-net forming process, die casting has the characteristics of high production efficiency, high dimensional accuracy, excellent mechanical properties, and can form thin-walled deep cavity castings with complex shapes and clear contours. In order to obtain high-quality integrated large-scale, complex, thin-walled aluminum alloy die castings for automobiles, the study of the mold filling flow behavior of thin-walled aluminum alloys has become a basic problem in the molding of such parts, because it is not only directly related to whether the parts can be formed completely, At the same time, it also affects the final microstructure and mechanical properties of the casting.

合金的充型能力指的是液态合金充满铸型,并获得形状完整轮廓清晰的铸件的能力,取决于液态合金本身的流动能力,同时受外界条件影响。当设置外界条件相同的情况下,液态合金的流动性主要取决于合金自身的成分。在实际生产过程中,必须了解合金的充型性能,才能更好地评估该合金在工程应用中的前景。The filling ability of the alloy refers to the ability of the liquid alloy to fill the mold and obtain a casting with a complete shape and clear contour, which depends on the flow ability of the liquid alloy itself and is affected by external conditions. When the external conditions are the same, the fluidity of the liquid alloy mainly depends on the composition of the alloy itself. In the actual production process, the mold filling properties of the alloy must be understood in order to better evaluate the alloy's prospects in engineering applications.

现有技术中,为了测试液态合金的流动性能通常会使用到测试模具。测试模具内设置有型腔,在测试时,将液态合金从测试模具的浇注口注入模具,使得液态合金流动填充至型腔中,来实现对液态合金流动性能的测试。In the prior art, test molds are usually used to test the flow properties of liquid alloys. The test mold is provided with a cavity. During the test, the liquid alloy is injected into the mold from the pouring port of the test mold, so that the liquid alloy flows and fills the cavity, so as to test the flow properties of the liquid alloy.

然而,现有技术中的测试模具仅设置单一形状的型腔,虽然一定程度上能实现对液态合金流动性能的检测,但无法精确测量液态合金流动性能和充型性能。However, the test mold in the prior art is only provided with a cavity of a single shape. Although it can detect the flow properties of the liquid alloy to a certain extent, it cannot accurately measure the flow properties and filling properties of the liquid alloy.
