The plastic parts are a width of meters, meters high, the thickness of to 4 cm between the car rear bumper. Overall size larger plastic parts, nonthreaded, so do not involve thread design. The design of the mold ejection ejection mechanism with a simple way of mandrel pulling mechanism. Mandrel ejection mechanism is the most typical simple stripping mechanism, its simple structure, easy to manufacture and easy to other injection mold design, mold design currently used in this paper in the hot runner advanced technologies, including the nozzle design, flowspecific parameters of choice and design, and so on. Throughout the design work in this paper use 3 D software Pro / E to plete the modeling products. In addition, also has drawn up the mold assembly drawing as well as each kind of Molding Parts drawing using CAD . This is that the first time makes use of the software drawing to carry out design on package mould , have carried out allround consolidation on what be learned knowledge， The significance is significant！ Keywords： Hot Runner； Injection Mould Design； Pro/E。 specific structure of the mold and die various 2 D, 3D rendering of the plan。 CAD Bumper Mould Design Abstract： The birth of mobile phones has changed many people39。此外還利用 CAD 繪制了模具裝配圖以及各種成型零件圖。頂桿脫模機(jī)構(gòu)是最典型的簡單脫模機(jī)構(gòu)，它結(jié)構(gòu)簡單，制造容易且維修方便。塑件整體尺寸較大，無螺紋，所以不需要涉及螺紋設(shè)計(jì)。相比其他注塑模設(shè)計(jì)，本文采用目前模具設(shè)計(jì)中先進(jìn)的熱流道技術(shù)，包括噴嘴的設(shè)計(jì)、流道板的具體參數(shù)的選擇與設(shè)計(jì)等等。汽車保險(xiǎn)杠 注射 模 具 設(shè)計(jì) 摘要 ： 隨著汽車工業(yè)的發(fā)展，汽車保險(xiǎn)桿作為一種重要的安全裝置走向了革新的道路，保險(xiǎn)桿除了有保護(hù)功能外，還要追求與車體造型的和諧與統(tǒng)一，追求本身的輕量化和表亮化。本文敘述了其注塑模具設(shè)計(jì)的一般流程，包括塑膠件的工藝分析；模具具體結(jié)構(gòu)的設(shè)計(jì)；及模具各種 2D、 3D 工程圖的繪制；熱流道技術(shù)；注塑成型設(shè)備的選擇；相關(guān)參數(shù)的計(jì)算與說明等等。 本塑件是一個(gè)寬度 米左右，高 米左右，厚度 ~4 厘米之間的汽車后保險(xiǎn)杠。這次設(shè)計(jì)的模具的頂出方式采用簡單脫模機(jī)構(gòu)中的頂桿脫模機(jī)構(gòu)。 在整個(gè)設(shè)計(jì)工作中，本文主要運(yùn)用 3D 軟件 Pro/E 以及 CAD 軟件 來完成產(chǎn)品的造型。這是第一次利用繪圖軟件對整套模具進(jìn)行設(shè)計(jì)，對所學(xué)知識(shí)進(jìn)行了全面鞏固，意義重大！ 關(guān)鍵詞 ： 熱流道；注塑模設(shè)計(jì)； Pro/E。s living habits, and the cell phone charge at GM because of its exceptional circumstances (price, convenience, etc.) get more people liked it, so in our lives was widely used. Block, which is connected rechargeable cell phone battery charging devices and the key positions. This paper describes the design of its injection mold of the general processes, including plastic pieces of technology analysis。 hot runner technology。 CAD 目錄 1 前言 ......................................................................................................................................... 1 2 塑件結(jié)構(gòu)與成型工藝分析 ..................................................................................................... 3 汽車保險(xiǎn)杠模具的設(shè)計(jì) ...................................................................................................... 3 汽車保險(xiǎn)杠的立體示意圖 ............................................................................................... 3 汽車保險(xiǎn)杠的二維視圖 ................................................................................................... 3 汽車保險(xiǎn)杠的結(jié)構(gòu)尺寸特征分析 ................................................................................... 3 塑件工藝性分析 ............................................................................................................... 4 塑料彎管原材料的選擇分析 .............................................................................................. 4 塑料的原材料的選擇 ....................................................................................................... 4 超 高沖擊強(qiáng)度 PP 性能指標(biāo) ................................................................................................ 4 3 成型工藝方案的確定 ..............................................................
