內(nèi) 容 提 要
CD盒的形狀較為復(fù)雜，所以模具設(shè)計(jì)中要考慮的因素有很多，除考慮它的出模、分型面，還需考慮它成型的質(zhì)量，表面光潔度等。更重要的是考慮它的制造難度和成本。所以我們設(shè)計(jì)應(yīng)認(rèn)真分析塑料制品的結(jié)構(gòu)，尋求最佳的設(shè)計(jì)方案。分型面的選擇也很重要，制件不是平直表面，制件的形狀很不規(guī)則，分型面的選擇既要考慮不影響制件表面的美觀，又要達(dá)到結(jié)構(gòu)要求。由于制品體積比較大，所以澆注系統(tǒng)的設(shè)計(jì)也很重要，在此次設(shè)計(jì)中我選頂面?zhèn)葷部?，并設(shè)有冷料穴。拉料桿采用倒錐形，這就解決了制品出模的問題。

Abstract
The machine of CD the shape of the cover than for complicacy, so want in the molding tool design the factor of the consideration have a lot of, a mold, cent type that divided by the consideration it, still need the consideration quantity that it model, surface clean an etc..More important consideration it of manufacturing difficulty with cost.So our design should analyze the construction that plastics product hard, design project looking for best. This time design most aims at the construction of the molding tool proceeded the design, because CD cover center contain a card dish, flank contain card door, so it must have the side take out organization, because of adopting a mold two space , so side take out construction I use two inclined lead the pillar guarantee, using inclined lead the pillar arouse the inclined slippery a sport, equiping the inclined slippery a smooth cent for, from but guaranteeing molding tool mold in fixed position with the fixed position.The choice of the cent type is too very important, a shape for is not straight and even surface, the piece of system is very irregular, the choice of the cent type since consider to do not affect a superficial beauty, attain the construction request again.Because producting the physical volume bigger, so sprinkle the design that note the system too very important, here a design inside I choose a side sprinkles, and establish the cold anticipating the cave.Pull to anticipate the pole adoption pour the form of Inclined, this resolved the problem of the ware a mold.
