對講機外殼注射模設計
摘要：本文詳細介紹了interphone注射模具的設計。基于PRO/E建模，在完成塑件結(jié)構(gòu)分析后，確定采用一模一腔、點澆口進料的三板式模具。根據(jù)基體尺寸，模架從標準模架庫中調(diào)用。針對塑件兩側(cè)有側(cè)凹，特優(yōu)化設計了斜頂機構(gòu)，并對該機構(gòu)的加工工藝、使用效果進行了闡述。同時，本文對澆注系統(tǒng)、成型零件、脫模機構(gòu)、斜頂桿側(cè)抽芯機構(gòu)、合模導向機構(gòu)、溫度調(diào)節(jié)系統(tǒng)、排氣系統(tǒng)和部分零件的加工工藝也做了完整的設計計算。
關鍵詞：注射模；側(cè)澆口；斜頂桿機構(gòu)
Abstractt ：
This text has introduced the design of the interphone injection mould in detail. Because of PRO/E modeling , after analyzing the structure of the interphone, confirms using a cavity ,point gate and three plate a mould. according to the matrices size, the mould shelf was choosed from the 3D mold base standard library. There were concaves in both sides of moulding , so optimizing design the angle ejector maching ,and furthermore the producing technics,the appliation affects are discessed in detail. At the same time,in this text the feedsysterm, shaping part, drawing of patterns organization , Organization of ejection force.,shut mould lead organization , temperature control system , exhaust system and the technology analyse of some workparts were designed and calculated totally.
Key words： injection mould；point gate ；angle ejector machine
