Reasons and Solutions for Deformation of Aluminum Alloy Die Castings

Summary: First analyze why aluminum alloy die castings are deformed? One is the overall or local deformation, and the other is that the geometry of the die casting does not match the drawings. The reasons for this situation are as follows. The structure of the casting is not good and the mold is opened early, which leads to insufficient rigidity of the casting and improper setting of the ejector pin, resulting in uneven force during ejection, improper gate position or too thick gate. It is easy to deform when the gate is removed, the local rough surface of the mold causes a large resistance, the deformation of the product when the product is ejected, and the temperature of the mold is too high, resulting in no solid state of the casting, or excessive force during the ejection, resulting in deformation of the product. For this kind of deformation problem of aluminum alloy die castings, the solution can be considered from the following points, improving the casting structure, reasonably adjusting the mold opening date and pressure holding, reasonably setting the ejection position and the number of ejectors, changing the gate thickness, strengthening the mold Handling, reducing demolding resistance, controlling local mold temperature, and maintaining mold thermal balance.
