The article introduced Pro/E software to having the powerful hypostatic function that build a model, of ANSYS software finite yuan of analysis function is very strong Dan Jianmo function is fragile. Be aimed at this kind of circumstance, put forward to be based on the collect of these two kinds of software to become analytic platform. Here platform falls, undertake to the temperature field of Die Casting mould finite yuan of analysis, get relatively accurate analysis result, can optimize the basis of the design as Die Casting mould. Die Casting mould is the important tooling of modern manufacturing industry. Aborning, its temperature field and thermal stress field are be not steady state, change along with time namely, each performance data all produces a change. Production carries out a proof, design of Die Casting mould, make after finishing, although discover an error. Also undertake bigger modification hard. Use numeric imitate technology before the mould is designed so. The temperature field that forecasts each position and thermal stress field distributing reach its change rule. Written guarantee to optimizing Die Casting mould compose is designed, improve cast quality, prolong mould service life, reduce cost, those who accelerate a product upgrade replacement, all have important sense. The application of technology of imitate of computer numerical value, offerred efficient way to dominate field of temperature of Die Casting mould and thermal stress field. Die Casting mould is finite yuan of concrete cast that the analysis involves. Its form is very complex, phase of pre-treatment of simulative of numerical value of as a result, namely hypostatic modelling and reseau analyse cent often spend a large number of time. Affected calculative precision and efficiency. Accordingly, undertake hypostatic modelling and unit analyse are divided well and truly. Make mould of unit analyse dispenses and cast structure appearance and mathematical model photograph harmonious. The authenticity that analyses a result to raising imitate and practical having important sense. ANSYS software is development of American ANSYS company is large and general finite yuan of analysis program, its analysis function is powerful. And field of can effective the temperature that seek solution, medicinal powder hot field and problem of much field coupling; But actually body builds modular function finite, can handle a few relatively simple models only, be competent hard the cast modelling with complex form. Pro/E is the professional CAD software that American PTC company develops, it is a hypostatic model system that is based on a feature. Its are main the function is changing a design at can undertaking convenient parameter. Build the model with complex form through what Pro/E can go to the lavatory quickly. Although it contains CAE module, but the CAE software that compares major still is not worth somewhat. Because this feasible solution is the advantage with both union, the model is built in Pro/E, obtain the model that approachs true cast appearance as far as possible. Guide undertake imitate is analysed in ANSYS next. Such, the temperature field that can use Die Casting pattern is emulated will solve real project problem. The collect of 1 ANSYS and Pro/E is become ANSYS direct and compositive in Pro/E, the model that makes Pro/E is generated can be complete guide in ANSYS. Need to have the interface of ANSYS and Pro/E the setting that be as follows: (1) issues installation to have Pro/E and ANSYS in the same operating system of the computer that be the same as a stage two kinds of software: (2) makes sure the version of two kinds of afore-mentioned software is compatible, the version of Pro/E does not get the version of the ANSYS of prep above the corresponding period: (3)ANSYS 10.

Pro; (6) opens Pro/E, menu column can appear: "ANSYS 10.

0 " option, ANSYSConconfmg and " ANSYS Ceom " show ANSYS is already compositive in Pro/E. (After 7) founds a new part, below menu of the Part in passing executive Pro/E " ANSYSCeom " , begin to transmit; Perhaps guide in ANSYS executive FileimportPro/E person file. ANSYS direct and compositive in Pro/E, whole transition can be in do not break away from Pro/E and ANSYS undertake below the circumstance of these two software, realized Pro/E and ANSYS to not have thereby seam join. Means of this kind of join guides the person's model won't happen be out of shape and of line range missing, analytic calculative precision is tall. 2 those who be based on the field of temperature of Die Casting mould below compositive platform is finite yuan of Die Casting pattern that the analysis builds I-shaped bridge with Yu Zhu. Actually body modelling is shown 1 times like the graph, mould total span is 0.

5m. Foregone molten steel is filled model before. Model initiative temperature is antrum 25 ℃ , its ambient air temperature is 25 ℃ . If the performance data of mould material and steel is expressed 1, 2 are shown, air convection coefficient is) of 65W/(m2 · ℃ . The temperature field that uses ANSYS imitate mould and cast distributings. Graph the 1 mould exterior that casts I-shaped bridge pursues 2.

1 undertake finite yuan of analytic pre-treatment (the three-dimensional model that 1) finishs the mould that casts I-shaped bridge with the modelling function module of Pro/E. To facilitate the ANSYS below compositive environment undertakes the processing of the unit, the casts I-shaped bridge mould model that makes in Pro/E integrates use international system of unit. (Of 2) model guide, start ANSYS directly in Pro/E. Pro/E is finished after building a model, click entree sheet directly " ANSYS 10.

0 " , " ANSYSCeom " . The system can open ANSYS automatically, use " Plot " in menu " Volumes " option, can show hypostatic model come (2) seeing a picture. Graph the model of 2 cast (3) reseau differentiates (build finite yuan of model) . Reseau differentiates is a very important segment in building a model, the stand or fall that reseau differentiates will affect the accuracy of computational result and computational plan directly, what because reseau differentiates,meet even is unreasonable and bring about computation not convergent. Graph 3 to differentiate the model after reseau. Graph 3 differentiate the model after reseau (attribute of 4) setting material. In material attribute dialog box, according to the performance data that sets mould material and steel. 2.

2 finite the processing seeking solution of yuan of analysis (1) adds tie load. Bring to bear on convection border condition is) of 65W/(m2 · ℃ , ambient air temperature arrives for 25 ℃ add in the surface inside the mould to suffer on convection percussive border. Will initiative temperature brings to bear on to cast the mould of I-shaped bridge for 25 ℃ . (2) seeks solution. Make stable state analysis first, determine initiative condition, undertake transient state is analysed next. After time situation long setting ends can finish automatically by the computer. 2.

3 finite yuan aftertreatment and result show the aftertreatment is the relevant operation that point to an examination and analyses the result that seek solution. This also is one of the most important segment in the analysis, the temperature that because the ultimate goal of any analysises is for research,casts I-shaped bridge mould distributings reach its be heated to be out of shape circumstance. ANSYS offerred the way of a variety of indication results, if the graph shows, isopleth graph, trochoid graph, list shows etc. Among them the graph shows is a kind of very intuitionistic and significant result shows pattern, and can show different analytic result according to different analytic goal. If imitate analysis result pursues 4 ～ are shown 7 times. Graph distributinging graph of field of temperature of 5 30s of distributinging graph of field of 4 initiative temperature when temperature of 6 cast center asks metabolic graph center of 7 moulds coping to temperature is followed at any time metabolic curve 3 summary (what 1) built two to have representative CAE and CAD software is compositive, applicable ANSYS software asks according to different manufacturing condition, change different parameter, new executive order flows, can reach in different production condition (include pouring temperature, sex of mould stuff other people and performance data of casting alloy hot physics) the field of temperature of Die Casting model below is numeric imitate, its eventuate next the numeric imitate of field of one meet an emergency offerred cast thermal stress information. (2) is like imitate result to cannot satisfy a requirement. In can returning Pro/E, undertake iteration modification, till be over of didymous mould optimize a design. (Method of this kind of numeric imitate saved 3) a large number of time, shape to cast craft and mould design have important sense. Can be in the project is actual in try to popularize application.
