[0001] The utility model relates to the technical field of die-casting molds, and more specifically, it relates to a die-casting mold for automobile chassis parts with an insert added to the moving inner mold. Background Art

[0002] The automobile chassis is an important part of an automobile. The main function of the automobile chassis is to receive the power of the engine, make the automobile move, and ensure its normal driving. The manufacturing processes of automobile chassis parts include casting, forging, machining, welding, etc. Among them, most of the casting of automobile chassis parts adopts the die-casting forming method. Molten alloy materials are injected into the die-casting mold under high pressure. After cooling and solidification, automobile chassis part products with complex shapes and precise dimensions can be formed.

[0003] Die-casting molds are very crucial components in the die-casting process. They determine the shape, dimensional accuracy, and surface quality of the castings.

[0004] Although die-casting forming has the advantages of high production efficiency, high dimensional accuracy, and suitability for casting complex shapes, the finished products of automobile chassis parts are more complex in structure and have higher precision requirements compared with ordinary die-castings. During long-term die-casting, the die-casting mold is prone to damage, resulting in the precision of the formed product not meeting the production requirements.

[0005] Currently, the overall service life of the mold and the precision of the formed mold products can be optimized by adding inserts. However, in the use process of this kind of die-casting mold, problems such as incorrect installation leading to incorrect product shapes will occur.

[0006] Therefore, a die-casting mold for automobile chassis parts with an insert added to the moving inner mold is proposed. By adding an anti-fooling design to the insert, the probability of installation errors is reduced. By replacing the insert, the overall service life of the mold is increased, achieving the goals of reducing the probability of installation errors of the mold, increasing the overall service life of the mold, saving the economic expenses for maintenance and repair during the use of the mold, improving the performance of the mold, and having strong practicability.
