(the mould of canopy )摘要根據(jù)蓋塞塑件的生產(chǎn)批量、PS (聚苯乙烯)塑料的成型性能特點以及蓋塞的結(jié)構(gòu)特點,設計成蓋塞注塑模具較為合理。蓋塞為通用零件,其精度要求不高但由于結(jié)構(gòu)原因,需要成型外部螺紋,使模具結(jié)構(gòu)相對復雜,增加了裝配時的難度。為成型螺紋,模具結(jié)構(gòu)上需要采用螺紋抽芯機構(gòu),為便于螺紋型芯的抽出,模具采用齒輪齒條抽芯機構(gòu),即可采用普通臥式注塑機,由與塑件對精度要求不高,成型零件加工較為容易本模具采用一模兩腔,總體上該模具機構(gòu)簡單,制造容易,生產(chǎn)周期短,節(jié)約了企業(yè)加工成本,縮短了模具制造周期。關鍵詞:外部螺紋 螺紋抽芯 齒輪齒條機構(gòu)(the mould of canopy )AbstractModel the structure characteristics that the function characteristics and covers fill according to the production batch quantity, the PS( gather the styrene) plastics that the cover fills the piece of Plastics, the design becomes the cover to fill to note the molding tool of Plasticsto compare for the reasonable.The cover fills for the in general use spare parts, its accuracy request is not highBut because of the structure reason, need to model the exterior thread, make opposite complications of the molding tool structure, increased the assemble the difficulty of the hour.In order to model the thread, need to adopt the thread to take out the organization of core on the molding tool structure, draw out for a core of easy to thread, molding tool adoption the wheel gear tooth takes out the organization of core , adopting the commonness lie type to note the machine of Plasticsthen from having not high request to the accuracy with piece of Plastics, modeling the spare parts to process more easyThis molding tool adopts two antrums of one mold, total ascend that molding tool organization simple, make easily, produce the period short, economized the business enterprise to process the cost, shorten the molding tool manufacturing period.Keyword:The exterior thread thread takes out the tooth an organization of the core wheel gear
