Description

Technical field [0001] The invention belongs to the field of casting, and specifically relates to a manufacturing process of a diesel engine. Background technique [0002] With the rapid development of automobile products, automobile manufacturers are accelerating the development of complete vehicle products in the constant competition. Although the appearance and shape of the car body, materials and supporting parts will have an impact on the performance of the motor vehicle, the heart of the car-the engine, is the most important for performance, regardless of supply, price, and performance. Matching and other aspects will directly affect the performance indicators of newly developed models. [0003] At present, diesel engines have higher and higher requirements for fuel consumption, noise, service life, emission pollution, reliability, and self-weight. However, the casting process of diesel engines has many steps and complex processes. The material of the outer membrane is groun...

AI Technical Summary

Problems solved by technology

[0003] At present, diesel engines have higher and higher requirements on fuel consumption, noise, service life, emission pollution, reliability, and self-weight, and the casting process of diesel engines has many steps and complicated processes. The material of the outer film is ground and mixed and filled into the sand box for vibration. Extrusion molding requires a lot of equipment and facilities, many operators, high labor intensity, and low production efficiency; the outer mold material and sand box pressurized vibration molding have low strength and water content, resulting in pores and blisters in the cast castings. The pass rate of finished products is low; the energy consumption of melting and returning iron is relatively large, and it will cause pollution and damage to the environment, reducing the effective utilization rate of molten iron
