The die-casting engine bracket is an important part of the automobile engine suspension system. It mainly connects the engine and the vibration reduction element. During the operation of the vehicle, it usually needs to withstand road impact and engine vibration. Therefore, it has high requirements for its mechanical properties and needs to have sufficient strength, rigidity, and service life.
Its material is generally aluminum alloy, etc. The engine bracket die casting produced by the die casting process has the advantages of precise size, mechanical properties, dense internal structure, etc., and can be mass-produced.
However, during the casting process, due to the uneven wall thickness and complex structure of the engine bracket, it is easy to produce defects such as shrinkage and shrinkage holes, which will affect the strength and rigidity and endanger the driving safety of the car. In order to improve the comprehensive yield rate of die-casting parts of the engine bracket, die-casting process design is usually carried out, and numerical simulation is performed using relevant software to analyze the location and cause of possible defects, and then the process is improved and optimized to avoid the occurrence of casting defects.
For example, the die-casting process design of the engine bracket die-casting made of aluminum alloy includes the selection of parting surface, ingates design, cross runner design, etc. When selecting the parting surface, the plane where the projected area is located will be selected as the parting surface according to the structure of the casting; the design of the position of the ingates needs to consider making the metal liquid flow as short as possible to reduce heat loss and avoid direct impact on the core; the structural form of the cross runner depends on the shape, position, direction and size of the ingates, and its thickness also has a corresponding calculation method and a certain draft angle will be set for easy demoulding.
In short, the quality of engine bracket die castings is crucial to the performance and safety of the car, and its manufacturing process needs to be carefully designed and strictly controlled to ensure that all requirements are met. Engine bracket die castings made of different materials and processes may vary in performance and characteristics. The specific design and manufacturing will be adjusted and optimized according to factors such as the type of car, performance requirements, and the technical level of the manufacturer.
