Design and Optimization of Crankcase Integrated Die Casting Mold Casting System for Agricultural Cultivator Engine
The integrated die casting was used for the crankcase of agricultural cultivator engines to achieve product functional integration and lightweight.Due to the large size of casting and uneven wall thickness,the bottom surface of the casting during the molding process reveal more serious cold shut defects,and mold sticking phenomenon occurrs in some region.To eliminate these defects,Cast Supre software was used to analyze the die-casting process and optimize the design of the gating and exhaust system of the original plan.The auxiliary inner gate was introduced in the middle of the casting to increase the filling temperature of the bottom surface of the casting.Finally,the product qualification rate reached up to 97%by new scheme.
