題 目 充電器外殼注塑模具設計 摘要 I 充電器外殼注塑模具設計 摘要 本文主要介紹的是充電器外殼注塑模具的設計方法。首先分析了充電器外殼制件的工藝特點,包括材料性能、成型特性與條件、結構工藝性等,并選擇了成型設備。接著介紹了充電器外殼注塑模的分型面的選擇、型腔數目的確定及布置,重點介紹了澆注系統(tǒng)、成型零件、合模導向機構、脫模機構、定 距分型機構以及冷卻系統(tǒng)的設計。然后選擇標準模架和模具材料,并對注射機的工藝參數進行相關校核。最后對模具的工作原理進行闡述,以及在安裝調試過程中可能出現的問題進行總結、分析,并給出了相應的解決方法。 本文論述的充電器外殼注塑模具采用三板式結構,即澆注系統(tǒng)凝料和制件在不同的分型面脫出,采用一模四腔的型腔布置,最后利用推板將制件推出。 關鍵詞: 充電器外殼;注塑模;三板模;澆注系統(tǒng);脫模機構;定距分型機構 Abstract II The mould injection design of charger shell Abstract The designing methods of injection mould of the charger shell are mainly introduced in this paper. First, the technological characteristics are analysed, including material properties, forming characteristics and conditions, the process of the structure, the forming equipment is the parting line is selected, the number of cavities is specific introduction are made on gating system, cooling system,Molding parts, Steering mechanism, moulding mechanism, and spacer parting the standard mould bases and Mould materials are the technological parameters of the forming equipment is checked. Finally, problems that may emerge during the mold installation process are analysed and the appropriate solutions are provided. Threepence mould is used on the design of charger shell,that is pouring material and the plastic parts are ejected from different parting lines. there are four cavities in this mould,finally a stripper plate is used to push off the charger shells.
