摩托车后轮轮毂的模具设计
摘要:轮毂是踏板摩托车上极为重要的行驶部件和安全部件,应具有良好的综合力学性能,在正常行驶过程中不应发生变形和疲劳失效。而轮毂又属于形状复杂的零件,一般采用铸造方法使其成型。现在,广泛采用低压铸造来生产轮毂。模具在铸造成型方法中是至关重要的一部分,因此,它的设计和制造成了铸造质量的关键所在。
本文对轮毂进行实体造型更形象的了解轮毂的外形。并主要从摩托车轮毂的发展状况、铝合金的成型与铸造方法、低压铸造的工艺及特点,模具总体方案的选择以及模具结构的设计等方面介绍了轮毂低压铸造的模具设计。
该款轮毂的材料采用了铝合金材料(ZL101A),对轮毂的铸造毛坯进行了设计,使其能够满足铸造的工艺要求。设计中将低压铸造与压力铸造、金属型重力铸造、挤压铸造以及差压铸造等铸造方法进行了对比。分析了轮毂零件的特点以及轮辋的主要形式及其特点。另外,主要从铸件收缩率、铸型分型面、冒口的设置以及推出机构等几个方面介绍了模具设计的要点。通过示意图描述了模具的分模与合模的动作方式。并对铸造轮毂的边模进行工艺分析。

Abstract: Wheels is an extremely important ponents 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 plex 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 pared. . 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
