压铸模是日本模具行业的主要生产品种之一。其产量仅次于冲模和塑料模,与锻模相当。现在,压铸件的应用范围已从家用电器、照相机、摩托车、汽车、电器产品等行业逐步扩展到自动化办公机器、计算机、录象机等行业。随着应用范围的不断扩大,对压铸件的质量要求也越来越高。因而对压铸模的结构、质量、制造周期及成本也提出了更高的要求。有关压铸模具技术、压铸件牛产技术及生产组织的发展动态如下。1、对压铸件的质量要求主要是提高其内部的致密度,欲将压铸件内的砂眼减少到最低限
Die casting mold industry in Japan is one of the major production varieties. Its output is second only to die and plastic mold, and forging die quite. Nowadays, the application range of die-castings has been gradually expanded from the household appliances, cameras, motorcycles, automobiles, electrical products and other industries to automation office machines, computers, video recorders and other industries. With the continuous expansion of the scope of application, the quality requirements of die casting are also getting higher and higher. Therefore, the structure of the die-casting mold, quality, manufacturing cycle and cost also put forward higher requirements. Die casting technology, die casting cattle technology and production organization of the development of the following. 1, the quality requirements of the die-casting is mainly to improve its internal density, want to die-casting to reduce the blisters to a minimum
