Automobile die casting parts have some advantages that other die casting parts can not be compared, such as beautiful, light weight, corrosion resistance, etc., which makes it widely loved by users.
Especially since the automotive lightweight, automotive die-casting parts have been widely used in the automotive industry. Car die casting parts
(1) The chain shell is used to connect the cylinder block and the oil pan, and the chain shell has been tested by oil pressure and air pressure in the car, which puts forward high requirements for the quality of the product.
This kind of automobile die-casting parts will show deformation and external quality unqualified in the use, so we should try to ensure that the product has a small processing amount and deformation amount. Although the investment cost of such automotive die-casting parts is high, the consumption rate is also high, and the total cost is not too high for the large-scale consumption of the automotive industry.
(2) The engine block is the "heart" of the car, the key to the quality of the car is whether the engine quality is good, and the central part of the engine is the cylinder block, the cylinder block uses high-pressure casting or sand casting, but from the current comparison of the car engine, the mainstream models and car manufacturers are using aluminum alloy die-casting cylinder.
Although the cost of aluminum alloy die casting cylinder is higher than the previous two manufacturing methods, with the rise of oil and the development of automotive lightweight requirements, aluminum alloy die casting cylinder is more and more widely used by automobile manufacturers.
Because the heat conduction function of aluminum alloy is better than that of cast iron, the use of aluminum cylinder head and cylinder block can improve the shape of the engine, improve the thermal efficiency, and greatly improve the efficiency of the engine.
The casting process of the cylinder block is extremely complex, known as the "pyramid" in the technology of automobile die casting parts, and the "central secret" of the manufacturing technology and process of the cylinder block is mastered.
(3) Support parts for automotive engine, transmission and other key parts of the connection, although the appearance is not as good as the cylinder block, cylinder head and other key, but in essence the quality of such parts has a decisive role in the performance of the entire car. Such automotive die-casting parts play a major role in die-casting consumption.
(4) The oil pan is the lower half of the crankcase, also known as the lower crankcase, which is used to block the crankcase as the shell of the oil storage tank, avoid impurities entering, and collect and store the smooth oil flowing back from the friction surface of the diesel engine, dissipate local heat, and avoid the oxidation of the smooth oil.
Although the aluminum alloy die-casting oil pan is not as strong and durable as the steel plate stamping, it has the advantages that the steel plate oil pan does not have, that is, light weight and good heat dissipation.
The composition and strength of aluminum alloy die casting parts have a very important influence on the quality of automobile die casting parts. By adjusting the relevant elements, the tensile strength of automobile die casting parts can be increased, and the mobility can be improved.
Based on the design and manufacturing of automobile die-casting parts, the research of aluminum alloy die-casting technology and the direction of automobile development provide a huge market for die-casting parts consumption, and manufacturers should develop more automobile die-casting parts according to market demand.
