The development of mould technology in China has a new trend
In the past two years, China's domestic mould technology has made rapid progress, mainly manifested as: the popularization of mould integrated manufacturing unit and technology;Commercial Internet extends to mold and its industrial chain.3D printing is widely used in mold manufacturing.Intelligent die;The appearance and optimization of lightweight new material and large plastic mould;Mature technology of large progressive die;With standard parts refinement and so on.
(1) popularization of mould integrated manufacturing unit and technology.Mould in addition to the automatic feeding, stamping, laminated thickness measuring, grouping, combination of core and product output, the function such as hinge assembly connection, and the complex motion structure, mould heating, forging, local heat (organization) control, mould welding, tapping, inside local injection molding, die cutting, mould detection technology combination process.In particular, this exhibition on the plastic parts of the mould of the eager, boron steel mould is eager to pencil and motor iron core change new technology such as the cutting edge of marked a new epoch in mould integrated manufacturing unit.Mold products continue to be large, precision, high performance, integrated manufacturing units.
(2) the commercial Internet extends to the mold and its industrial chain.At present, many mould processing equipment enterprises have also connected with the Internet and actively built the "mould manufacturing + Internet" mode, which has strongly promoted the transformation and upgrading of the mould industry.
(3) wide application of 3D printing in mold manufacturing.3D printing is a new trend of mold cavity development.Metal material increasing reduction of material combination manufacturing technology is an important direction in the field of 3 d printing today, the current through 3 d layered material forming, based on high speed milling thickness contour reduction material finishing, the realization of high precision of complex metal parts manufacturing.
(4) intelligent mold.At present, in the plastic mold and die casting mold industry, there have been mold cavity pressure, temperature, flow, cooling process intelligent control mold.In addition, the intellectualization of mould processing equipment is also rapidly advancing the intelligent manufacture of mould.
(5) appearance and optimization of lightweight new materials and large plastic molds.With the development of the automotive lightweighting, lightweight material emerge in endlessly, mould domestic enterprises have begun to respond to this change, launched a new lightweight materials of automobile covering parts mould with large composite mould development.
(6) mature technology of large-scale progressive die, high speed and high reliability have become important characteristics of precision progressive die.At present, large progressive stamping parts are everywhere, the size of parts is getting larger and the shape is getting more and more complex, which shows that the technology of large progressive stamping has entered the mature stage.However, high precision progressive die requires more and more stability and reliability in production.Obviously, the mould design and manufacturing technology of the ultra-large forming parts and the small ultra-precision parts has become the hot spot of the mould enterprises.
(7) mold standard parts tend to be refined.In recent years, with the improvement of mold types and requirements, mold standard parts has become the important condition of mould enterprises to participate in international competition, many varieties, classification is the main trend in current mould standard parts.There are more and more traditional standard parts, and the quality requirements are higher and higher.New functional structure standard unit and more flexible standard parts are becoming more and more important, and become the new direction of new technology and innovation to enhance competitiveness.
It can be seen from the above that at present, China's mold technology has developed to another new stage, but it still needs to be optimized to achieve a bigger breakthrough.
