What is the design philosophy of the mould?
The domestic development situation of facing the 21st century, the enterprise to adapt to the development of market economy, as the national support industry of the automobile industry will increase production of light, the micro, cars, thus puts forward higher requirements on the precision of the die forgings. In the process of production, improving die life is a complex and comprehensive problem. All forging technology, especially the net net shape and approximate shape processing technology, to a large extent depends on the precision and quality, mould depends on the skill level of the mould. Mould technology is reflected in die design and manufacturing, and die life is related to the use of the process. ? Is of great economic benefit to improve die life, generally in the trial production mold tooling costs accounted for about 25% of the cost of production, and finalize the design production is only 10%.
In the early failure mode of the die, the fracture of the die, the collapse of the molds, the crack in the bottom of the cavity and the cracks in the bottom of the die. The factors affecting die life are more, and the design of die is the foundation of die life. The design of die design is the structure design of the die, the design of forming mould cavity and the determination of mould steel, mould hardness and so on. Mould manufacturing process refers to molding process, heat treatment specification and surface treatment technology. This paper discusses the measures to improve die life from two aspects: mould design and mould manufacturing.
The design and fabrication of precision volumetric mould and die life.
