复杂箱体类铸件的LFC用发泡模具的国产化实践摘 要 引进国外消失模成套设备后,迅速实现发泡模具的国产化是扩大铸造产量的关键之一。合力集团依托华中科技大学,在实施发泡模具国产化的进程中经历了三个阶段。三年来共开发出多种箱体铸件的发泡模具,不仅满足了本集团的需求,还为国内外其它企业配套生产箱体类铸件,使消失模铸造不断发挥效益。关键词:发泡模具箱体铸件消失模铸造引言箱体类铸件是比较适合消失模铸造(Lost Foam Casting)的一种类型。一般而言,箱体越复杂,消失模工艺越能发挥其优势。国外用LFC法生产箱体类铸件的公司有美国GM 的Saturn(生产球铁差动器壳体)和意大利FATA的Teksid(生产灰铁曲轴箱体)。国内用LFC生产箱体类零件的企业有:重庆南川通发特种铸造厂(生产载重车齿轮箱体);山西临猗华恩公司(生产差速器壳)和山西左权龙泉冶金铸造有限公司(生产变速箱壳体)。1998年初,安徽合力叉车集团(简称合力集团)引进德国消失模白区制模技术,其产品对象主要是叉车用各类箱体铸件,如变速箱体、变矩器及离合器壳体等。当时,国内已有数家企业引进国外消失模铸造设备,其中有的因模具国产化成为瓶颈,生产状况不尽人意。如今三年有余,合力集团LFC 生产形势很好,开发出十多套模具(其中箱体类模具六套),完全具备了模具设计、制造和开发能力。本文从技术上对合力集团所实施的模具国产化的三个阶段进行总结。第一阶段:设备引进和模具培训同步进行1998年,合力集团引进德国TEUBERT公司TVZ130/90成型机。该设备为全自动卧式成型机,垂直开模,吸盘取件;该设备采用德国发泡成型模具,生产出叉车液力变速箱体泡沫模样(模片分为三块)。所生产的箱体铸件重达60多公斤。在引进设备的同时,合力集团领导意识到:要扩大LFC生产规模,就必须迅速实现模具国产化。因此,在与德方商务谈判中,中方坚持将模具培训列入合同。因为引进的德国成型机和冷粘合机在国内都是第一台,针对德国设备的发泡模具设计,国内没有设计参考资料。为更好地消化吸收德国技术,合力集团邀请华科大参与组团,赴德考察模具设计和制造。三人在德培训十天,考察的主要收获如下:1. 接受了多模独立汽室的设计概念,摸清了模具与设备的相互连接匹配关系。所谓独立汽室机构指在一台成型机上可同时安装数付模具,而每付模具的汽室相互独立,可按各自的成型工艺制作不同的泡沫产品。德国成型机工作面尺寸大(1300X900),可采用多模独立汽室模具。为此,该设备配备有4套物流接头,提供蒸汽、冷却水、压缩空气以及真空等,以便在成型机上安装四套发泡模具。独立汽室模具机构的设计概念是德国设备所独有的;
