内容提要
CD盒的形状较为复杂,所以模具设计中要考虑的因素有很多,除考虑它的出模、分型面,还需考虑它成型的质量,表面光洁度等。更重要的是考虑它的制造难度和成本。所以我们设计应认真分析塑料制品的结构,寻求最佳的设计方案。分型面的选择也很重要,制件不是平直表面,制件的形状很不规则,分型面的选择既要考虑不影响制件表面的美观,又要达到结构要求。由于制品体积比较大,所以浇注系统的设计也很重要,在此次设计中我选顶面侧浇口,并设有冷料穴。拉料杆采用倒锥形,这就解决了制品出模的问题。

Abstract
The machine of CD the shape of the cover than plicacy, 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 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 anization, 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 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 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 to anticipate the pole adoption pour the form of Inclined, this resolved the problem of the ware a mold.
