14、te、guide post in turn because of the difference of molds structure.下面以電鍍件為例,對細部保養作例圖說明(因為電鍍件對油污敏感性要求比一般塑件要高.因此,清理保養更加徹底.)Use electroplated part as example to introduce details maintenance.(The maintenance of electroplated part is more thorough than others because its requests of greasy dirt sensitiv

15、ity is more than others.),contents,從拆模開始.Start from separating mold.,首先,用天車將模具放在整洁的工作台面上,准備好拆模工具.Set mold on the clear working table by workshop traveler firstly and prepare the tools.然后,將公模與母模分開,准備拆公模Then separate the core and cavity,prepare to separate core.,第一步,公模底板上與模框連接的螺栓卸下然后將公模固定板和模腳一起拉出放于一旁S

16、eparate the screws that join cores base plate with mold frame then pull out the stable plate and mold foot together.注意點matters needing attention:對于大模具,直接拉出比較困難,可以先用拔模器拔掉底板上的導柱.拉出時要平穩,防止折彎折斷型芯.所卸螺釘導柱等放在預備好的工作盤中.It is difficult to pull out the big mold.Had better pull out the guide post on the base pl

17、ate firstly.Pull it smoothly to avoid damaging the core.Must set the screw and guide post in the prepared plate.,將,頂出底板上的螺釘卸下拆出頂出底板Separate the screw of eject base plate then separate it.注意點:Matters needing attention:如果復位彈簧是在導柱中內置的,卸螺釘時應該先卸對角,以免頂出板卡死,不易脫出.Separate the screws on the diagonal line fir

24、 in the hole of embedded lump with small oilstone and electric drill assembled steel brush.用小油石(320#以上)除去鑲塊表面的銹,并用噴槍清洗,吹乾.Use small oilstone(over 320#)to clean the rust on the surface of embedded lump and clean it with spray gun.,頂針孔或是小型芯孔內的銹污也可用頂針或型芯來清理,只要用相應的頂針或者小型芯在孔內反复抽動几次即可.Can clean the rust d

25、irt in eject pin hole or small hole of the core with eject pin or core pin,just use the corresponding eject pin or small core pin to twitch several times in the hole.,頂針孔及小型芯孔清洗,用去漬油對模仁和模框噴洗乾淨后吹乾,尤其是模仁孔內部一定要清洗乾淨.Spurt cleaning oil on core and mold frame to wash it then dry it,especially clean the ho

26、ld of core.注意點:Matters needing attention:清理的順序一般是先側面,再正面,再反面,最后又正面.In general the clean order is flank firstly,then front,then reverse side and front again at last.,模仁和模框清洗,開始公模部分組裝 Start to assemble the core組裝時注意導柱 入子等清潔,潤滑Pay attention to clean and lubricate guide post and core pin etc.when assemb

27、ling it.,接下來,Assemble embedded lump and core pin用乾淨的手裝上鑲塊及入子.Use clean hands to assemble embedded lump and core pin.注意點:Matters needing attention:注意鑲塊入子的編號要和模仁上保持一致,裝入后要檢查是否裝正确.Confirm the no.of embedded lump and core pin is same as the core,inspect the assembly is correctly or not.,裝上鑲塊及入子.,將模仁裝入裝好

28、防水圈的模框中,并用螺釘緊固好.Assemble core in the mold frame installed waterproof rings and fix it with screws.,裝防水圈及模仁,用乾淨的布條將頂針及導柱擦乾淨,在導柱上塗上少許白油潤滑.再將頂出板裝入公模板,并將所有的頂針依次裝好.Clean guide post and eject pin with clean cloth,smear a lot of white oil on guide post to lubricate it.Then install eject plate in core plate

29、,assemble all eject pin in turns.注意點:Matters needing attention:注意頂針是否裝反,對于有斜梢的模具還要檢查斜梢是否裝正确.Inspect the installing condition of eject pin and slanting pin.,裝頂針及公模板,用乾淨的布條對頂出底板稍作擦拭,再將頂出板和頂出底板合好并用螺釘緊固好.Slightly clean eject base plate with clean cloth then assemble the eject plate with base plate and f

30、ix it with screws.注意點:Matters needing attention:頂出底板裝入時要平穩,否則容易使裝好的頂針震出.鎖螺釘時先鎖對角.鎖好后最好再次檢查頂針等是否裝正确.Install eject base plate smoothly,otherwise the installed pin will be shaken out.Install the screws on diagonal line firstly.At last inspect the install condition of eject pin etc.,頂出板和頂出底板組立,用油石將模腳和底板
