90°彎管注塑模的的設(shè)計

里面有詳細的圖紙，ppt,說明書，外文翻譯。


[摘要]注塑成型是熱塑性塑料成型的主要方法之一，可以一次成型形狀復(fù)雜的精密塑件。以90°彎管注塑模具設(shè)計為例,介紹了常用注塑模具的設(shè)計方法和流程。首先根據(jù)塑件的結(jié)構(gòu)，對其進行工藝分析,然后選擇注塑機并確定型腔數(shù)目,接著確定成形方案:分型面設(shè)計、澆注系統(tǒng)設(shè)計、型腔型芯的設(shè)計、導向機構(gòu)的設(shè)計、脫模機構(gòu)設(shè)計和側(cè)向分型抽芯機構(gòu)設(shè)計等。最后進行注塑機工藝參數(shù)校核,包括注射量、鎖模力和注射機閉合高度等方面。并詳細介紹了模具的工作過程。在設(shè)計的同時，進行了部分的分析說明。該模具結(jié)構(gòu)設(shè)計巧妙，操作方便，使用壽命長，塑件達到技術(shù)要求。本文采用的設(shè)計方法和流程對其它不同結(jié)構(gòu)產(chǎn)品的注塑模具設(shè)計有一定的參考價值。

The design of elbow injection mold with 90°

【Abstract】Molding thermoplastic injection molding is one of the main methods can be a complex shape forming of precision plastic parts. To 90 ° elbow injection mold design, for example, introduced a common injection mold design methods and processes. First, the structure of plastic parts according to their conduct process analysis, and then select the number of injection molding machine and to determine the cavity, and then determine the shape programs: sub-surface design, the design of cavity-type core, lateral core pulling mechanism design type, cast system design, design-oriented institutions, the cooling system design, demanding mechanism design. Finally, injection molding machine parameters checked, including the injection volume, clamping force, injection pressure, mold thickness and the injection machine
shut height and so on. And detailed working process of the mold. While in the design, carried out part of the analysis shows. The mold structure cleverly designed easy operation, long life, and plastic parts to the technical requirements. In this paper, design methods and processes of the other products of different structural design of plastic injection mold has some reference value.
