摩托车灯罩模具设计说明书
摘要
本文介绍了摩托车灯罩的模具设计过程。本设计对塑件在模具中的位置和分型面位置、选择浇注系统与排溢系统、成型零件的结构、合模导向机构、推出机构、侧向分型与抽芯机构、温度调节系统的设计方案做了充分的论证,并优化选取最合理的设计方案。对于塑件的侧孔处理,采取了斜导柱侧抽芯脱模,带有脱模斜度的孔,则利用塑件的脱模斜度替代侧抽芯,简化了模具结构。通过对型芯支承板和型腔板的计算,保证了模具的优良使用性,优化了模具的结构设计,使得模具结构紧凑。

Abstract
This text introduced the mould design process of the motorcycle lampshade. Determining the plastic part in mould and selection of the parting line, the feed and runner system design, the core/cavity creation structure design, the guide pin and guide bush , the plastic ejector structure , external undercuts and cooling and ejection system designing, they all be analyzed in this text, and choose the best design. With the hole in the side of product deal with Angle Pin, if the hole oblique, make the use of tilted detrusion straight, so the structure of the mould will be simplify. By the caculate of the cavity plate and backing plate, make the mould used working order, optimized
the mould structure, make the mould pact.
Keywords: injection mould; Raised mold;Core; Later parting Core with Angle Pin;
