Requirements and technical analysis of mold surface finishing

Finishing of mold surface is one of the difficult problems that cannot be solved well in mold processing. It is also one of the reasons that mold fitters are labor-intensive and become bottlenecks in mold processing. It is especially reflected in the final assembly process of harder metal and die-casting molds. China Mould Network pointed out that my country is still mainly manual grinding and polishing, not only the quality is unstable, the cycle is long, and the workers' working environment is poor, which restricts the development of casting molds in my country to a higher level.

For the surface finishing of complex cavities and some slits, traditional machining methods are no longer adequate, and other technological measures, such as electrochemical or electrochemical mechanical finishing technology, must be adopted. With the continuous development of science and technology, the processing technology requirements of various molds are getting higher and higher. Improving the speed and quality of mold polishing to make my country's mold manufacturing technology reach the world's advanced level has become an urgent and important issue.

In the mold surface finishing technology, the main ones can be divided into two parts, namely traditional finishing technology and non-traditional finishing technology. Traditional finishing technology is mainly manual grinding and polishing and now developed mechanical finishing; non-traditional finishing mainly includes chemical polishing, electrochemical polishing, electrolytic grinding, electrochemical mechanical finishing, ultrasonic processing, magnetorheological change Polishing, laser polishing technology and electric spark polishing, etc.
