Abstract
本发明公开了一种笔记本后盖孔位冲压模，该笔记本后盖孔位冲压模包括上模和下模通过固定于上模的导向柱相互定位咬合；所述上模包括上模板、凸模固定板、垫板和卸料板，所述凸模固定板、垫板和卸料板依次叠加后通过销钉和螺丝连接固定于上模板，凸模固定板上还安装有料探针和钨钢凸模。通过上述方式，本发明能够使坯料在冲压模上快速一次成型，保证了孔位的精度，大大提高了生产效率和产品合格率。
Description
一种笔记本后盖孔位冲压模
技术领域
[0001] 本发明涉及冲压模，特别是涉及一种笔记本后盖孔位冲压摸。
背景技术
[0002] 随着科学技术的发展，冲压件的应用越来越多，尤其是电子产品制造领域，随之冲压技术也在不断的发展。冲压技术中最为关键的技术就包括冲压模具的结构设计，现代冲压技术对冲压模具的要求越来越高。笔记本后盖孔位精度要求大，加工难度大。现有的笔记本后盖孔位是利用冲压模具通过多次冲压和定位加工成的，成型后的产品因为定位误差造成产品报废率高，成本高，而且加工效率也较低。
发明内容 [0003] 本发明主要解决的技术问题是提供一种笔记本后盖孔位冲压模，能够使坯料在冲压模上快速打孔成型，大大提高了生产效率和产品合格率。
[0004] 为解决上述技术问题，本发明采用的一个技术方案是：提供一种笔记本后盖孔位冲压模，该笔记本后盖孔位冲压模包括上模和下模通过固定于上模的导向柱相互定位咬合；所述上模包括上模板、凸模固定板、垫板和卸料板，所述凸模固定板、垫板和卸料板依次叠加后通过销钉和螺丝连接固定于上模板，凸模固定板上还安装有料探针和钨钢凸摸。
[0005] 优选的是，所述下模包括下模板、垫板和凹模板，所述垫板和凹模板依次叠加通过销钉和螺丝固定于下模板，所述凹模板上对应凸模的位置设有冲切孔，凹模板上避开冲切孔的位置设有料定位块，下模板和垫板对应冲切孔的位置设有废料出孔。
[0006] 本发明的有益效果是：本发明能够使坯料在冲压模上快速一次成型，大大提高了生产效率和产品合格率。
附图说明
[0007] 图I是本发明一种笔记本后盖孔位冲压模的一较佳实施例的结构示意图。
