原稿-收音機底蓋注塑模具設(shè)計說明書

1、I摘要塑料注射模具是成型塑料的一種重要工藝裝備，通過對收音機底蓋塑料模具設(shè)計能夠全面的了解塑料模具設(shè)計的基本原則、方法.并能較為熟練的使用UG、AUTOCAD軟件進行塑料模具設(shè)計提高自己的繪圖能力。為今后從事設(shè)計工作打下了堅實的基礎(chǔ)。隨著現(xiàn)代工業(yè)發(fā)展的需要，塑料制品在工業(yè)、農(nóng)業(yè)、日常生活和軍事等各個領(lǐng)域的應(yīng)用范圍越來越廣，質(zhì)量要求也越來越高，中國已經(jīng)成為全球最大的塑料市場之一，塑料制品產(chǎn)量全球第二。本次主要設(shè)計是對收音機底蓋注射模的設(shè)計

2、重點對塑件的成型原理、原料選用和注射技術(shù)進行分析。通過根據(jù)形狀、尺寸、精度及表面質(zhì)量要求的分析結(jié)果，確定所需的模塑成型方案，制品的后加工、分型面的選擇、型腔的數(shù)目和排列、成型零件的結(jié)構(gòu)、澆注系統(tǒng)等。關(guān)鍵詞：關(guān)鍵詞：工藝方案；模具結(jié)構(gòu)；注塑機；模具設(shè)計AbstractAbstractPlasticinjectionmoldplasticfmingisanimptantprocessequipmentthroughthetoothbrush
