利用材料的可塑性与流动性特点,对某些材料进行成形加工的模具在第二次世界大战后在技术上获得迅速发展,目前在汽车、家电、塑料制品等许多方面广泛应用。模具生产已成为一个不可缺少的重要产业部门。利用模具成形比切削加工具有不少优点,如:(1)品质均一;(2)加工时间短;(3)进行少无切屑加工;(4)适合于大批量生产;(5)效率高、成本低。而模具生产也有它本身的一些特点:(1)模具大多为单件、少量生产,机械化、自动
Utilizing the plasticity and fluidity characteristics of materials, the molds for forming certain materials have been rapidly developed technically after the Second World War and are now widely used in many fields such as automobiles, home appliances and plastic products. Mold production has become an indispensable important industry sector. The use of mold forming than cutting has many advantages, such as: (1) uniform quality; (2) processing time is short; (3) less no chip processing; (4) suitable for mass production; (5) low cost. The mold production also has some of its own characteristics: (1) molds are mostly single, a small amount of production, mechanization, automatic
