OptimizationandImprovementoftheStructureProcessofthe Die-CastingParts fortheDryingRoad of theWashing Machine[Abstract] The structure of the diecasting parts manufacturability was analyzed based on the washing machine, The optimization idea of the local structure process of the diecasting parts was put forward. Considering the factors such as material properties, assembly requirements, usage functions, die-casting die development and filling molding, the structural process requirements such as uniform wall thickness, fillet transition and slope direction were analyzed. The concrete, reasonable and feasible process improvement methods were put forward. The optimization and improvement of diecasting parts structure technology can improve the productivity and qualified rate of the diecasting parts, and simplify the die structure, reduce the manufacturing cost and prolong the service life of the diecasting die.
Key words: drying road of washing machine; uniform wall thickness; improvement of process structure
