螺絲刀工具箱的虛擬裝配及其蓋板模具設(shè)計(jì)

摘要

螺絲刀工具箱，是一個(gè)結(jié)構(gòu)不是很復(fù)雜但是卻十分的精巧的產(chǎn)品，由于本設(shè)計(jì)有兩大部分：一部分是螺絲刀工具箱的整體結(jié)構(gòu)的設(shè)計(jì)，另一部分是蓋板的模具設(shè)計(jì)，本文進(jìn)行了其螺絲刀工具箱的整體結(jié)構(gòu)設(shè)計(jì)以及蓋板注塑模具一模兩件的設(shè)計(jì)，并詳細(xì)闡述了設(shè)計(jì)過(guò)程。

基于UG進(jìn)行了結(jié)構(gòu)設(shè)計(jì)，然后虛擬裝配后導(dǎo)出IGS格式到keyshot4.0進(jìn)行了渲染，讓其顏色更加的接近實(shí)際情況。

基于模流分析技術(shù)優(yōu)化了模具的成型工藝參數(shù)、澆注系統(tǒng)及冷卻系統(tǒng)。在考慮制件外觀的同時(shí)，確定了制件澆口位置在蓋板的側(cè)面；優(yōu)化后的成型工藝參數(shù)為：模具溫度100℃、熔體溫度300℃、注射時(shí)間1.9s；蓋板采用側(cè)澆口、一模兩腔成型，建立澆注系統(tǒng)后預(yù)測(cè)了其成型注射壓力和鎖模力，為注塑機(jī)規(guī)格選擇提供了依據(jù)；冷卻水溫及IPC時(shí)間分別為80℃和30s。根據(jù)模流分析結(jié)果進(jìn)行了成型設(shè)備的選擇。

基于UG注塑模向?qū)K進(jìn)行了該產(chǎn)品的模具設(shè)計(jì)。然后基于proe5.0進(jìn)行模架的設(shè)計(jì)，澆注系統(tǒng)及冷卻系統(tǒng)由模流分析確定。模具設(shè)計(jì)的難點(diǎn)在于幾個(gè)關(guān)鍵部位的抽芯，在此采用了斜導(dǎo)柱抽芯機(jī)構(gòu)、和側(cè)滑塊抽芯機(jī)構(gòu)等。完成成型零件的設(shè)計(jì)后調(diào)用標(biāo)準(zhǔn)模架，實(shí)現(xiàn)了整副模具的3D設(shè)計(jì)。最后繪制了2D裝配圖及零件圖。

Summary 

  Screwdriver kit, is a very complex structure but not very sophisticated products, due to the design of two parts: one part is the overall structure of the screwdriver toolbox design, the other part is the cover of the mold design, this paper carried out its the overall structure and design of the screwdriver toolbox injection mold cover a two-piece mold design and detail design process.

  First,based on the structural design UG were then exported to the virtual assembly IGS format keyshot4.0 were rendered, let the color is more close to the actual situation. 

  Secondly help mold flow analysis techniques to optimize the process parameters of mold forming, casting systems and cooling systems. In considering the appearance of the same parts, parts to determine the location of the gate at the side of the cover; molding process parameters optimized for: mold temperature of 100 ℃, the melt temperature of 300 ℃, the injection time of 1.9s; cover with lateral water mouth, forming a two-cavity mold, after the establishment of the gating system to predict its pressure and clamping force injection molding, injection molding machine specifications selected to provide a basis; cooling water temperature and IPC time was 80 °C and 30s. Molding equipment were selected based on mold flow analysis.

   The product has been designed based mold injection mold UG Wizard module. Then design, gating system and cooling system based on proe5, 0 conduct mold flow analysis to determine the mode. Difficulty lies in mold design several key parts of the core pulling, this uses a bevel pillar core-pulling mechanism, and side slider pulling mechanism and so on. After the completion of the molded part is called standard mold design, 3D design to achieve a whole deputy mold. Finally, draw a 2D assembly drawings and part drawings. 

Keywords: virtual assembly; injection mold; CAE analysis; Bevel column; side slider;
