1引言
日用品,有时采用精度和强度不太高的塑料传动,由于塑料具有可塑性强,密度小、比强度高、结缘性、化学稳定性高、外观多样的特点,因而受到越来越多的厂家及人民的喜爱。塑料工业是新兴的工业,是随着石油工业的发展而应而生的,目前塑料制件几乎已经进入一切工业部门以及人民日常生活的各个领域。随着机械工业电子工业,航空工业、仪器仪表工业和日常用品工业的发展,塑料成型制件的需求量越来越多,质量要求也越来越高,这就要求成型塑件的模具的开发,设计制造的水平也须越来越高。本文也就对日用品中的笔盖模具设计过程进行阐述。
Daily necessity, sometimes adopt the not that high plastics of accuracy and strengths to spread to move, because the plastics has the plasticity strong, the density is small, higher than strength, the knot good luck, the chemistry stability is high, diverse characteristics of external appearance, as a result be subjected to more and more factories house and the people's plastics industry is a newly arisen industry, is along with the development of the petroleum industry but should but living of, the plastics system piece almost have already entered each realm of the whole industry sections and people's daily lifes c
