氣壓瓶蓋注塑模設(shè)計(jì)

摘 要
本設(shè)計(jì)主要針對(duì)氣壓瓶蓋外觀質(zhì)量要求和尺寸精度配合較高、結(jié)構(gòu)形狀和制造工藝較復(fù)雜的情況。在外觀和結(jié)構(gòu)設(shè)計(jì)上采用流線型設(shè)計(jì)、光亮表面處理；模具設(shè)計(jì)上采用了潛伏式澆口、開合模定位裝置、多推桿推出機(jī)構(gòu)和回路冷卻系統(tǒng)等多項(xiàng)措施。實(shí)現(xiàn)高效、質(zhì)量高、成本低的產(chǎn)品設(shè)計(jì)、生產(chǎn)原則。
設(shè)計(jì)過程中翻閱一些產(chǎn)品設(shè)計(jì)和模具設(shè)計(jì)有關(guān)的參考資料和文獻(xiàn)，結(jié)合繪圖軟件Pro/Engineer Wildfire 4.0和AutoCAD 2008對(duì)氣壓瓶蓋和模具的初步設(shè)計(jì)。對(duì)于產(chǎn)品的外型設(shè)計(jì)和模具設(shè)計(jì)，主要包括以下這些方面。外型設(shè)計(jì)：基本長(zhǎng)度尺寸、拔模斜度、最小過渡圓角、最小壁厚、粗糙度等方面的確定；模具設(shè)計(jì)：注射機(jī)的選擇、澆注系統(tǒng)、成型零件、合模機(jī)構(gòu)、脫模機(jī)構(gòu)和冷卻系統(tǒng)的設(shè)計(jì)，繪制模具零件圖和裝配圖等。

Design of the Injection Mould for the Lid of Atmospheric Pressure Bottle
ABSTRACT
This design is mainly for the situation of quality requirements for the Lid of Atmospheric Pressure Bottle and with a high dimensional accuracy, the shape of Construction and complicated manufacturing process. In the design of appearance and structure, it will adopt with sleek design and bright surface. Mold design using submarine gate, opening and closing mold positioning device, multi-putting introduction equipment and a number of measures such as loop cooling system. Thus achieve the efficient, high quality and low cost product design and production principles.
The design process has referred to some product design and mold design-related references and documents, and combined with mapping software Pro / Engineer Wildfire 4.0 and AutoCAD2008 in the Lid of Atmospheric Pressure Bottle and the preliminary design of mold. As to the outlook design and mold design of the product, is mainly including the following areas: Outlook design: the confirmation of the basic length dimensions, taper angle, the minimum fillet, minimum wall thickness, roughness, etc: Mold design: the choice of injection machine, the design of injection system, molding parts, clamping device, mold body and cooling system, and drawing die parts diagrams and assembly drawings, etc.
