汽车零部件的模具设计

摘要 目前国外模具行业广泛采用CAD/以M技术，并通过数控机床进行加工，大大的缩短 了产品开发周期和制造周期，提高了模具的技术含量，降低了成本。相比之下，我国模 具行业还有很大差距，特别是在汽车零部件生产制造方面还不具备为国产汽车(尤其是 轿车)全面配套供货的能力，参与国际竞争的能力很弱。针对目前国内汽车零部件行业 情况，我们必须根据国际汽车零部件工业的发展，综合分析国外经验，结合我国实际情 况，采取有利措施，提高我国汽车零部件工业的竞争力。 本课题通过对离合器壳设计过程的分析，以UG、Aut0CAD软件为基础，进行了离合 器壳模具的开发，同时仿真了离合器壳模具的数控加工，实现了从实物到生产的一体化， 利用参数化实体造型的方法，突破了AutoCAD二维实体造型功能不足的局限，为汽车零 部件更加高速、快捷的造型、生产提供了一种切实可行的办法。 关键词:离合器壳设计模具设计数控加工CA。/C胡技术 BSTRACT NowforeignmouldindustryhasgreatlyshortenedthemouldofmakingPeriod， heightenedthemouldoftechniealeontentandredueedtheeostbymakinguseofCAD/CAM teehniealandnumeriealeontroltool.Tothecontrary，mouldindustryinoureountryhas laggedbehind，esPeeiallyintheautomobilePartindustry.Whiehdoesn’thastheabilityto suPPorteomPletePartsforautomobilesmadeinehina.China，5abilitytoeomPetewith internationalal止omobileindustry15weak.ConsideringtheaetUaleomPlexioninoureouniry andthedeveloPmentofintemationalautomobilePartindustry，wemustmakePowerful measurestoimProveabilitiestotaPProduetandtoeomPetewithintemationalautomobile Partindustry， Baseoncornmereialsoftware一UGandCAD，weoPenuPthemouldofeluteh’5hull， simulatethenumeriealeontrolandalsorealizetheProeessfromPractiealitytoProduetion.
