[摘 要] :
分析了吸塵器彎管連接頭的工藝特點，介紹了成型該塑件注射模的對開式側抽芯結構及滑塊連桿式圓弧側抽芯機構，闡述了模具的工作過程及注意事項。模具設計中關于抽芯機構是一個難點，合適的抽芯機構直接關系到產品的合格與否，設計時既要考慮模具的機構要求，同時也要考慮模具設計的成本問題和制品要大批量生產等因素，最終采用液壓抽芯機構，應付產品在脫模過程中的彎頭，提供了較大的抽拔距和抽拔力，并且通過連桿和軸的運動使得抽芯順利抽出。本文重點介紹了這種抽芯機構及其設計要點，以及產品生產過程中的一些注意點。

Abstract :
Has analyzed the craft characteristic which the vacuum cleaner elbow piece company attaches, introduced takes shape should model to inject the mold to start out from opposite directions folio the type side to pull out the core structure and the slide long rod circular arc side pulls out the core organization continually, elaborated the mold work process and the matters needing attention. In the mold design about pulls out the core organization is a difficulty, appropriate pulls out the core organization to relate directly to the product is qualified or not, when design already must consider the mold the organization request, at the same time also needs to consider the mold designs the cost question and the product want factor and so on mass production, the connecting rod and the axis movement to pull out the coresmoothly to extract. This article introduced with emphasis this kind pulls out the core organization and its the design main point, as wellas in product production process some limelight.
Keywords : hydraulic pressure ; gear and rack ; injection mould; the arc side is smoked the core
