Analysis of imitate of CAE of model of 1 foreword Die Casting is to be based on cast numeric imitate to emulate a technology, through be opposite Die Casting aluminium alloy fluid is filled model field of temperature of model of the temperature field in caky process, Die Casting has the field of going from place to place in the process, aluminium alloy liquid emulation imitate, analyse the limitation that cast may appear, evaluation mould gating system, cooling system and parameter of Die Casting craft are reasonable, undertake optimizing to its thereby. Imitate of CAE of Die Casting model analyses a process to include 3 shares commonly: After designing Die Casting model above all, the input of STL interface file that will output undertakes to pre-treatment module reseau differentiates the computational module that; uses Die CastingCAE system next undertakes full model, the computational analysis; of caky process and mould temperature field uses aftertreatment module to undertake the result shows finally, analyse the limitation that cast may appear, judgement mould is designed and pouring technology design is reasonable, those who be design of Die Casting model and gating system optimize provide academic basis. Use AnycastingDie Casting process to emulate analytic software now, model of Die Casting of the lid before be opposite is in design process complementary analyse with CAE imitate, optimize Die Casting gating system and design of structure of Die Casting model according to imitate result. 2 before structure of shell spare parts analyses a scheme 1 for some lid before new-style engine, material is aluminium alloy A380 character, heavy 3.

125kg, 70mm of × of 310mm of × of 430mm of over all dimension, average wall thick 4mm. The lid parts to wait for spare parts photograph to join with lid of filter, condenser, oil pump before, basically rise prop up, defend, cooling action. Requirement of cast interior quality is stricter, stoma of spare parts sealing contact surface must not is more than 0.

5mm, stoma of other treatment surface must not be more than 2mm. Air-tightness experiment asks: It is high-pressured oil duct with condenser and filter connective oil duct, the requirement issues minutely leakage quantity to be less than 10cm3; whole housing to ask minutely below the pressure of 70kPa leakage rate is less than 10cm3 in 721kPa pressure. The graph builds 3 gating system before 1 engine design and optimize 3.

Because cast has porosity and air-tightness to ask,1 gating system is designed, according to cast umbriferous area, fill to the enough power that lock up a model assures cast model reach in-house mass, introduce 1 model 1, the Die Casting of machine of Die Casting of horizontal cold room that chooses the force that lock up a model to be 12500kN. According to experience, combinative plan 1Die Casting characteristic, stand by filter and need of condenser a side to decorate slide block and model core and runner cannot be opened in this a side, because this consideration adopts a plan,2 show gating system. Runner height takes 3mm inside, apply UG software to have branch to cast model with gating system three-dimensional build a model, cast shrinkage is taken 0.

55% , the graph is shown 3 times for sketch map of mould cent face. Graph 2 gating system pursue Nextpage3 of 3 cent face sketch map.

Analysis of imitate of 2 gating system sets chamfer of cast, gating system, overflow, pattern above all piece wait for three-dimensional number model to output STL file, guide the pre-treatment module of Anycasting software undertakes reseau differentiates respectively. Next requirement of qualitative, initiative worth, heat conducts the material of set cast and mould the craft parameter such as dimension of condition, runner. In Die Casting process, parameter of Die Casting craft has fluid of pressure, filling velocity, metal to fill up the temperature of characteristic, mould antrum and alloy, these parameter affect metallic fluid fill and final cast quality. When applied Anycasting undertakes the model circulates an analysis, above all the Die Casting of aluminium alloy fluid that situations of these parameter imitate production issue set fills up, caky process. If parameter of chosen Die Casting craft expresses 1 to show, if the physical performance with cast and mould quality material expresses 2 to show. Graph 4 for model antrum fills up process imitate, after metallic fluid passes runner, from brim of cast a side along model antrum wall fill, in 0.

4027s, place of high-pressured oil duct (A is in) produce a spirit appearance. In 0.

4154s, filter place (B is in) produce an apparent spirit appearance, final stuff place is in the upright ministry that connects with filter (C is in) . Graph 4 model antrum fills up process imitate pursues after 5 gating system are optimized model antrum fills up process imitate Nextpage4.

Analysis of imitate of field of 2 moulds temperature and mould structure optimize imitate of mould temperature field to be like a graph 6, 7, 8, 9 are shown. According to metallic fluid analysis of caky process imitate and imitate of mould temperature field are analysed, in metallic fluid the existence in caky process isolates dangerously fluid photograph area, should in mould temperature field higher position decorates local and compulsive cooling structure, control a model to provide local temperature and metallic juice caky speed. Local extruding texture adds in as conterminous as filter place, the shrinkage cavity of place of large to the spare parts wall undertakes filling shrinking. According to analysis of mould temperature field, the temperature in as caky as outfit condenser connecting place process is higher on the spare parts, easy sticking to mould, consider this place to have packets of bigger close power, the proposal increases fixed die roll out an orgnaization, if pursue,10 are shown. 5 try a model to use optimized gating system design, production pattern, hand-in-hand travel tries model and Die Casting production, manufacturing Die Casting dimension precision and interior cast quality to all satisfy design requirement. The scientific design Die Casting model, imitate analyses system of CAD/CAE of model of Die Casting of 6 last words to be an organic whole repeatedly, shortened not only mould design, production cycle, and optimized Die Casting craft, reduced the factitious element effect to mould quality greatly, it is to make sure the mould produces quality and the significant step that produce cycle, also be to reduce the cost, important way that enhances competition ability.
