原稿-收音機底蓋注塑模具設計說明書

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計能夠全面的了解塑料模具設計的基本原則、方法.并能較為熟練的使用UG、AUTOCAD軟件進行塑料模具設計提高自己的繪圖能力。為今后從事設計工作打下了堅實的基礎。隨著現(xiàn)代工業(yè)發(fā)展的需要，塑料制品在工業(yè)、農業(yè)、日常生活和軍事等各個領域的應用范圍越來越廣，質量要求也越來越高，中國已經成為全球最大的塑料市場之一，塑料制品產量全球第二。本次主要設計是對收音機底蓋注射模的設計

2、重點對塑件的成型原理、原料選用和注射技術進行分析。通過根據(jù)形狀、尺寸、精度及表面質量要求的分析結果，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、成型零件的結構、澆注系統(tǒng)等。關鍵詞：關鍵詞：工藝方案；模具結構；注塑機；模具設計AbstractAbstractPlasticinjectionmoldplasticfmingisanimptantprocessequipmentthroughthetoothbrush
