摘要
塑料模具作为塑料工业的基础,随着市场经济的飞速发展受到了极大的挑战。汽车的内饰件、灯具反光镜等塑制品的复杂外形,而钟表、DVD光驱用传动齿轮等塑制件又有很高的精度要求。很短的制模周期、相当的寿命是模具制造的又一重要指标,例如有的只需几十、几百模次(可用简易快速制模法),有的如制瓶用吹塑模却需要上千万模次,制造周期要求越来越短。各种特殊的成型方式的出现等等,都要求塑料模具技术有相应的提高。而计算机技术的飞速发展,适时的给模具技术配上了腾飞的翅膀,彻底改变了手工作坊式的模具设计和制作。在模具设计中广泛的运用CAD(计算机辅助设计),不但抛弃了沿用上百年的图板,而且由于计算机的快速运算和大容量的内存,使得复杂曲面的生成、快速的作图以及丰富制模技术经验的综合、推广成为可能,不少CAD软件已具有某些智能化的功能。例如,有些CAD软件可以运用人机对话的形式,输入塑料制品的某些外形特征(外形主要尺寸、分型面位置、抽心位置、脱模方向等)即可以画出模具总图。
模具技术是一种综合型技术,要求从事模具技术工作者,密切注意和学习相关知识,并运用到实际工作中为模具行业的发展而努力。
