The mold design of motorcycle rear wheel
Student name :WuHao Class :078105329
Supervisor : Luo HaiQuan
Abstract: Wheels is an extremely important safety components and moving parts of aPedaling Motorcycle , which should have good mechanical properties, in the normal courseof driving should not be taken deformation and fatigue failure. And Wheel is a part of complex shape. Generally casting method used to shapee. It widely used low-pressure casting to produce wheel currently. Die Casting is a vital part in molding method. So its design andmanufacture is the key of casting quality.
This paper making solid mode-ling for wheels in order to understanding more image about the shape of the wheel ，and it mainly introduces the Wheel mold design of low pressure die casting, fromthe development of motorcycle wheelAluminum alloy molding and casting methods, process and characteristics of Low-Pressure Casting,the choice of the overall program dies the design of die structure Introduced die casting the wheel design by low pressure
Materials of this wheel used alloy material (ZL101A) .The paper Analyses the wheel parts and wheels characteristics of the main forms and characteristicsduring the program design the low-pressure casting and pressure casting, metal-gravity casting, pressure squeeze casting and pressure casting, and other methods are compared. . The Casting blank of the wheel enables it to meet the technological casting requirements. In addition, to introducethe principal Mold design elements, it covers several aspects including the contraction rate of type-casting, Riser set up the institutions and the launch. The actions of Die-Die and mold are described by the maps.process analysis he side-mode for casting wheel
Keywords： Wheels low-pressure casting mold design
