摩托車燈罩注塑模
摘 要
本文介紹了摩托車燈罩模具設(shè)計(jì)過(guò)程。本設(shè)計(jì)對(duì)塑件在模具中的位置和分型面位置、選擇澆注系統(tǒng)與排氣系統(tǒng)、成型零件的結(jié)構(gòu)、合模導(dǎo)向機(jī)構(gòu)、推出機(jī)構(gòu)、側(cè)向分型與抽芯機(jī)構(gòu)、溫度調(diào)節(jié)系統(tǒng)的設(shè)計(jì)方案做了充分的論證，并優(yōu)化選取最合理的設(shè)計(jì)方案。對(duì)于塑件的側(cè)孔處理，采取了斜導(dǎo)柱側(cè)抽芯脫模，帶有脫模斜度的孔，則利用塑件的脫模斜度替代側(cè)抽芯，簡(jiǎn)化了模具結(jié)構(gòu)。通過(guò)對(duì)型芯支承板和型腔板的計(jì)算，保證了模具的正常使用，優(yōu)化了模具的結(jié)構(gòu)設(shè)計(jì)，使得模具結(jié)構(gòu)緊湊。

Injection Mold for motorcycle lampshade
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 structure compact. And we has demonstrated the structure of the mould in the design of the blow mould, such as the form of knife edge and the cooling system. We has compared the form of the co-extrusion mould ,and we has selected the type of the co-extrusion machine accord the need of the producing condiction of the product.
Keywords: injection mould; Later parting Core with Angle Pin; processing teachnology.
