贴膜手机板面注塑模具设计
摘 要
注塑模CAD/ CAE/ CAM技术是先进制造技术的基础和重要组成部分,正向集成化、网络化和智能化方向发展,对我国模具工业的发展起到了重要的推动作用。注塑模具的设计与制造,其质量要求越来越高、研发周期越来越短。
贴膜手机板面精度要求高,结构及其曲面造型复杂,需要从三侧面抽芯,模腔布局设计比较困难。采用proe 工具,根据客户提供的贴膜贴膜手机板面三维数模,完整地设计出了贴膜手机板面注塑模。
首先对制品进行了工艺分析,然后详细阐述了模具的设计过程,包括:分型面的确定,型芯和型腔的创建,标准模架的确定,浇注系统、冷却系统、滑块抽芯机构和脱模顶出机构的设计,同时对相关机构进行了校核计算。最后对其成型零件进行了加工工艺分析,编制了机械加工工艺规程。
借助于先进的CAD技术,大大缩短了注塑模设计与制造周期,提高了模具的技术含量,降低了成本。

ABSTRACT
It is foundation of an advanced manufacturing technology and important component that the injection mould CAD/CAE/CAM technology, to integrated networked to develop with intelligent direction, play a important role to of our country mould development of industry. Mould plastics design and manufacture of mould, quality requirement its more and more high researching and developing cycle to be shorter and shorter. The precision of the cell-phone panel is expected much, structure and curved surface model are complicated, need to smoke the core from three sides, the mould is more difficult in one of overall arrangements design. Adopt proe tool, according to three dimension moulds of cell-phone panel that the customer offered , designs the panel note of the cell-phone to mould completely.
The precision of the cell-phone panel is expected much, structure and curved surface model are complicated, need to smoke the core from three sides, the mould is more difficult in one of overall arrangements design. Adopt proe tool, according to three dimension moulds of cell-phone panel that the customer offered , designs the panel note of the cell-phone to mould completely.
Have carried on the craft to analyse to the products at first, then explained the design process of the mould in detail, including: Sureness the person who divide, type core and establishment , type of, standard mould sureness of shelf, pour system , cooling system , slip piece smoke core organization and drawing of patterns is it produce the design of organization to carry, checked calculating to relevant organizations at the same time . Carry on processing technology analyse to its shaping part , work out mechanical processing technology rules finally.
With the aid of advanced CAD technology, have shortenned the note and moulded and designed and made cycle greatly, have raise the technological content of the mould, has lowered costs.
