Mold design and development trend
The publisher:admin Release time:2015-4-22 8:42:47 Reading:68Time

    Characteristics of the development of the whole industry is currently more varieties of products, updating fast, fierce competition in the market. In order to adapt to the user pressing demand for short delivery time,high precision, low manufacturing cost, the mold will have the following trends:

    (1) die design by experience design stage to the theoretical calculation and computer aided design of the direction of development, CAD/CAM/CAE technology is widely used in the mold industry, the mold structure is more scientific and reasonable, can greatly improve the machining precision molds, shorten the cycle ofmold design and processing, reduce the product development time.

    (2) the mold to the high precision and large and small development direction. 10 years ago, the general accuracy of precision molds for the 5um, has now reached 2 3um, precision mould will soon be listed 1um.With the miniaturization and precision components increase, some mold machining accuracy within 1um,which requires the development of ultra precision machining, such as to reduce the amount of manual operation.

    (3) the multi-purpose compound mold will be further developed. Multicolor and multi material plastic moldingdie there will be rapid development, this mold shorten the production cycle and assembly cycle, the futurewill be developed in different areas and applications.

    (4) with the development of hot runner technology, hot runner mold in the proportion of plastic mold will gradually increase. Because of using hot runner mould aluminium alloy board technology can improve the productivity and quality of parts, raw materials, and can greatly save the parts therefore, the development of hot runner technology in foreign countries is very fast, has been very common.

    (5) the application of mold standard parts will be more widely. Standardized mold and mold standard parts of the application can greatly influence the mold manufacturing cycle. The use of mold standard parts can not only shorten the manufacturing cycle of mould, and can improve the quality and reduce cost, therefore, the application of mold standard parts will be more widely, such as plastic, stamping mold, thimble, sleeve, screw and spring, and the formation of standard parts.

    (6) the prospect of rapid economic mold. Now many varieties of small batch production of the era, the mode of production in twenty-first Century accounted for the proportion of industrial production will reach more than 75%. On the one hand is the product life cycle is short, on the other hand, the pattern changes frequently, mold production cycle shorter the better, so the development of rapid economic mold more and more attention. For example, the development of various superplastic material to make the mold, using epoxy resin (E), polyester (P) or (M) the filler metal, glass and other objects (G) enhanced production of simple mold, E, P, P-M, E-G, E-G-M, P-G-M to make the mold, the main characteristics of this mold is of simple manufacturing process and the precision is easy to control, low shrinkage, low price, high life, alsocan cover mold with cement and plastics production cars, this kind of mold in the United States, Japan and other countries have applied, but also the need to improve and expand the scope of application. In the low melting point alloy mold, mold spray, mold, casting mold, mold, plastic mold ceramic layer, epoxy resin modeland optical modeling of rapid economic mold will be further developed, quick change mold and fast exchanging punch will also be growing. In addition, quick die change device and rapid test mode device technology will be developed and improved with computer control and mechanical hand operation.

    (7) with the improvement and development of plastic molding, gas assisted die mold and adapt to the high-pressure injection molding process will follow the development of. The precision of plastic parts sizeprecision, geometric accuracy and precision of appearance (i.e., gloss, color) 3, in order to achieve theaccuracy, will continue to study the technology and high-pressure injection molding and injection compression molding process and mold. In injection molding, the biggest influence factors of forming precision is the molding shrinkage, high pressure injection molding resin shrinkage can be reduced,increasing the stability of plastic size. Die requirements of good rigidity, high pressure, especially in precision mold cavity to be quenched, gate seal better, mold temperature should be controlled accurately. Gas assisted injection molding technology has been more mature, it can improve the appearance and intrinsic quality of plastic parts, products with low injection pressure, deformation is small and easy to form the wall thickness difference of the products and other advantages, and can save raw materials and improve theproductivity, thereby greatly reducing the cost. The mold has appeared in China's gas assisted, and achieved good results.
