The macro sense, auto parts mold mold is a general term for the entire car, such as injection molds, stamping molds and forging molds. Auto cover means constitute an automobile body or cab, engine and chassis cover shaped body surface and internal car parts. Automotive engine cover has cover, car cover, left and right side of the car around the front and rear doors, front, rear, left, right fender, trunk lid, engine front support plate, engine front apron, front Frame, front fender, wheel fenders, rear quarter panels, luggage compartment cover, rear cowl top cover, cover, front quarter panels, front panels, the front wall cover, front fender and engine enclosures.
Auto cover both exterior decorative parts, is closed shell-like force components. Cover any minor defects are painted on the surface after diffuse light and cause damage to the aesthetic appearance, and therefore does not allow covering the surface ripples, wrinkles, scars and other damage to the brink of surface beauty defects. This mold precision is very high.
Now, as people raise the level of awareness of things, users are also becoming increasingly demanding requirements of the mold, "high-precision, excellent quality, low prices, shorter delivery time and a long service life," the car to better meet the user's requirements, how in a short time with the cheapest cost to produce the highest quality products, has become a major problem.
Compared with other developed countries, the majority of the domestic auto industry in mold design and manufacture of CAD / CAE / CAM technology is imperfect, integrated design and production association is not formed. Companies not in three-dimensional software applications, summed up part of a business on a true sense of their programs and ideas, can only emulate the success stories abroad, feeling the stones. But the difference between structure and uniqueness of the mold, so that designers face the same kind of mold design, they often have to follow the same design process design is completed, mold design efficiency and thus always unsatisfactory. With the continuous development and progress of science and technology, concurrent engineering, artificial intelligence techniques, parametric modeling and design, and many other disciplines related technology continues to be linked with the modeling industry. Degree of specialization mold CAD / CAE / CAM rising, began to take shape in the CAD / CAE / CAM integrated system network architecture, eye-catching mold intelligent technology, advanced manufacturing technology are marked nascent CAD / CAE / CAM system toward specialization, artificial intelligence, networking and integration and other four aspects of development.
However, the domestic production of low-tech mold, almost all of the high-end cars and precision stamping die mold are dependent on imports. China's mold production technology gap with the international advanced level are:
(1) Die enterprise comprehensive strength of the weak, not high degree of specialization. Because the vast majority of our automobile mold companies affiliated with major automotive group, fear of new models of technical information disclosure, largely limited technical exchanges between enterprises of the mold, thus affecting the entire mold enterprise technology development and progress.
Mold manufacturing enterprises a full range of services for the automotive group, making it difficult to form their own expertise in certain aspects of their professional knowledge accumulation is also very difficult.
(2) Computer Application Technology capacity is insufficient. Even if all the big companies have the basic three-dimensional CAD / CAE / CAM software, but due to the quality of personnel, habits and design efficiency and other factors, the current design does not achieve meaningful three-dimensional, three-dimensional exploration of practical experience accumulated with The actual requirement is the difference between heaven and earth.
Practical experience (3) mold design and production, accumulation of data and information is low, the lack of a reasonable and effective measure accumulation.
To achieve our automotive body panel dies not tryout, a successful loading mode, to a large extent reduce the tryout period and production costs, it is necessary to develop a relevant and efficient software platform. Most businesses to UG platform, use one of the related modules and secondary development capabilities, research and development on the basis of an automotive die design parameters UG framework on the integration of modeling simulation technology for its
