Plastic products industry is an emerging industry. With the rapid development of China39。s booming plastics industry, economic modernization in China is playing an increasingly important role. Plastic products in people39。 關(guān)鍵詞 : 模具設(shè)計(jì) 注塑模具 聲控開關(guān) Pro/E II Abstract Into the 21th century, China39。隨著我國國民經(jīng)濟(jì)持續(xù)高速發(fā)展已逐步發(fā)展壯大，自上世紀(jì) 90年代以來，塑料行業(yè)一直保持在 10%以上的增長速度，已成為輕工業(yè)的支柱產(chǎn)業(yè)之一。 隨著塑料加工工業(yè)持續(xù)快速發(fā)展，塑料制品在工業(yè)、農(nóng)業(yè)、軍事及人民生活的各個(gè)領(lǐng)域得到廣泛的應(yīng)用，塑料制品的研究、生成與應(yīng)用開發(fā)得到迅速發(fā)展，塑料模具的設(shè)計(jì)、制造技術(shù)也隨之不斷 提高。首先運(yùn)用 AutoCAD 對塑件進(jìn)行二維圖的繪制，再運(yùn)用 Pro/E 軟件繪制塑件的三維模型。 塑料制品在人們的日常生活中隨處可見，因此其注塑模具的需求也日益增多，市 場前景廣泛，而且因?yàn)椴煌芗耐庑尾煌?，注塑模具也就有了很大的不同? 畢業(yè)論文 聲控開關(guān)面板注塑模具設(shè)計(jì) Voice switch panel injection mold design 系 別：機(jī)電與自動(dòng)化學(xué)院 專 業(yè) 班：機(jī)械設(shè)計(jì)制造及其自動(dòng)化 0801 姓 名： 學(xué) 號(hào)： 202229110xx 指導(dǎo)教師： 2022 年 5 月 I 摘 要 進(jìn)入二十一世紀(jì)以來，中國塑料工業(yè)取得了令世人矚目的成就，實(shí)現(xiàn)了歷史性的跨越。蓬勃發(fā)展的中國塑料工業(yè)，在中國現(xiàn)代化經(jīng)濟(jì)建設(shè)中發(fā)揮著越來越大的作用。 本設(shè)計(jì)是關(guān)于 聲控開關(guān)面板的 注塑模具設(shè)計(jì)，通過注塑機(jī)注塑成形零件。介紹了注塑機(jī)的選用，塑件的選材，澆注系統(tǒng)的設(shè)計(jì)，分型面及型腔數(shù)目的設(shè)計(jì)，導(dǎo)向、脫模及冷卻系統(tǒng)的設(shè)計(jì)等，以及對模具的校核。 塑料制品業(yè)是一個(gè)新興大行業(yè)。 隨著 CAD/CAM/CAE 技術(shù)的引用，更是顯著提高了模具設(shè)計(jì)的效率，減少模具設(shè)計(jì)過程中的失誤，提高了模具和塑件的質(zhì)量，縮短了生產(chǎn)周期，降低了模具和塑件的成本。s plastics industry has made achievements that attracted worldwide attention, achieved a historic leap. China39。s daily life everywhere, so the injection mold growing demand, broad market prospects, but also because of different shape with different plastic parts, injection molds will have a big difference. This design is about the voice switch panel injection mold design, injection molding parts by injection molding machine. First, the use of plastic parts for twodimensional AutoCAD mapping, then the use of Pro / E software to draw threedimensional model of plastic parts. Describes the selection of injection molding machines, plastics material selection, design of gating system, the number of subsurface and cavity design, direction, stripping and cooling system design, as well as checking on the mold. With the sustained and rapid development of plastic processing industry, plastic products in the industrial, agricultural, military and people39。s national economy has gradually grown since the last century, 90 years, the plastics industry has remained at over 10% growth rate, has bee one of pillar industries in light industry. With the CAD / CAM / CAE technology, reference, but also significantly improve the efficiency of mold design, mold design process to reduce errors and improve the quality of molds and plastic parts, shortening the production cycle, reducing mold and plastic parts Costs.
