The invention provides a fluidity test die for die-casting alloy, which comprises a die body, a pouring gate, a flow channel and a cavity, wherein the pouring gate, the flow channel and the cavity are arranged on the die body; the die cavities at least comprise a first die cavity and a second die cavity, the first die cavity and the second die cavity are respectively communicated with the flow channel, the first die cavity is in one of a rectangular shape, a convoluted shape, a stepped shape, a bent shape and a cylindrical shape, and the second die cavity is in the other of the rectangular shape, the convoluted shape, the stepped shape, the bent shape and the cylindrical shape.

Please refer to fig. 1 and fig. 2 in combination. The embodiment provides a die 100 for testing the fluidity of die-casting alloy, in particular to a die for testing the fluidity of die-casting aluminum alloy, which can accurately test the flow capacity and the filling performance of the alloy, better evaluate the prospect of the alloy in engineering application and provide auxiliary support for the optimization of alloy components and performance.

The die body 10 may include a male die and a female die that are matched with each other, and the die body 10 may further include functional components such as an ejector pin, a fixing member, and a positioning member, which are known to those skilled in the art, but are not innovative to the fluidity testing die 100 for die-casting alloy, and are not described herein again.

That is, at least two cavities 30 are provided, and the flow channel 20 is an inlet for liquid alloy to enter the cavities 30. Therefore, when the liquid alloy is injected, the liquid alloy flows into the runner 20 through the pouring gate, then flows into the cavity 30, and finally is condensed to form the fluid sample casting 200.
The shape of the first cavity 31 is one of a rectangular shape, a convoluted shape, a stepped shape, a curved shape and a cylindrical shape. Wherein, rectangular means: the overall space of the cavity is a rectangular parallelepiped, i.e. the cross section (the section obtained by slicing the mold body in the direction of the angle shown in fig. 1) and the longitudinal section (the section obtained by slicing the mold body in the transverse direction shown in fig. 1) of the cavity are both substantially rectangular, so that after the liquid alloy is formed in the space, a rectangular parallelepiped fluid sample casting 210 is finally obtained. The winding shape means: the cavity is centered at a point of the mold body 10, the cavity of the cavity surrounds the periphery of the point, and cavity units extending in different directions and communicating with each other are arranged in the cavity. If one cavity unit extends along the length direction (or tends to the length direction), and the other cavity unit communicated with the cavity unit extends along the width direction (or tends to the width direction), when the liquid alloy flows into the cavity, the liquid alloy flows towards different directions when flowing to different cavity units due to the guidance of different cavity units. So that after the liquid alloy is formed in this space, a fluid sample casting 220 is finally obtained which is surrounded back and forth. The stair-stepping refers to: the cavity is divided into a plurality of (at least two) cavity units which are communicated with each other, and the thickness of the cavity units is gradually reduced or gradually increased along one direction, so that when the liquid alloy is formed in the space, the fluid sample casting 230 with different thicknesses can be finally obtained.

The second cavity 32 is in the shape of another one of a rectangular shape, a convoluted shape, a stepped shape, a curved shape, and a cylindrical shape. That is, the shape of the second cavity 32 is different from the shape of the first cavity 31, and if the first cavity 31 is rectangular, the second cavity 32 is one of a winding shape, a step shape, a bending shape, and a cylinder shape; when the first cavity 31 is in a winding shape, the second cavity 32 is in one of a rectangular shape, a step shape, a curved shape and a cylindrical shape … ….
