| With the China's open door policy get further, and deeper, China is gradually becoming the base of global manufacture, the Mold industry, as the essential part of the manufacture, grows fast. The fast growth of Chinese economy demands more on Mold industry, also, provided the huge power push its growth. In past 10 years, Mold industry growing fast, gained growth rate at 15 % annually, China is ranked the 3rd place in gross of the Mold products over the world. Lately, Mold industry evolves quickly, mainly those of larger, precise, complicated and long life Molds and standard molding products gain fast growth, which is above industry's average. China is still a big step behind developed country , not only on the technical aspects, but also lack of management skills, more work need to be done on deployment of CAD/CAM/CAE, high speed cutting, new materials, advanced molding technology. The progress of software and computer technology, molding CAD/CAM/CAE technology is the way of Mold designing and manufacturing. New trend is that utilizing information technology and advanced technology advance the traditional Mold industry, it will get next level if it adopt the digital control technology, fast shaping technology, high speed cutting and super fine manufacturing technology. Molds are the essential parts of manufacture assembly line, among those industries of electronics, automobiles, motors, instruments, home electronics and communications, 60% to 80% of parts are produced via Molds. Molds are "multiplex", the value of the products produced via Mold are over ten folds, or even hundred folds of Mold's value. The level of producing molding products is a major aspect of the country's manufacture industry; it is the key deciding point to the quality of the products, efficiency of the manufacturing and the capability developing the new products. The key of the product formed rapidly in molds, is the raw material's shaping ability. Dynamic stress of metal being shaped mainly depend on temperature, compounds of the metal material, and the structure of the molds, those factors are the key factors affecting, the quality of the products produced by those molds, its durability and also the safety of assembly line. If not distributed properly of those dynamic stresses, it could produce a lot of useless products, higher the products cost, or the mold itself could crash, it would danger the life of the workers. Traditionally, the mold design is based on the imperial formulas, can not simulate the actually producing process, and estimate the distribution of those dynamic stress, there are too many possibility during this type of designing phase. Shaping process is the complicated process, producing cost are huge, particularly for those extra large pieces, it is worth well to do some physical or digital simulation. This article described iterative solver technology and simulate the producing process via Software of ANSYS, calculating the stress distribution during different phases of molding, view the results of the molding, based on those, predicting the results of mold structures, provide the support for mold design. In Chapter one, introduced the background of this project, then, the theory of rapidly forming process of the molds, after that, described the contents and methods of this project used; In Chapter two, introduced the Mold producing software Pro/engineer, focus on the process of the building the molds; In Chapter three, detailed described ANSYS software's contact analysis, dynamic solver technology, and thermal analysis technology, particularly described the related industries and steps of how to apply those three methods; In Chapter four, described the functionality of the ANSYS LS-DYNA, and focus on ANSYS LS_DYNA 's Structural Analysis.
