注塑模設(shè)計
模具簡介
模具型腔可賦予制品其形狀，因此在塑料加工過程中模具處于非常重要的地位，這使得模具對于產(chǎn)品最終質(zhì)量的影響與塑化機構(gòu)和其他成型設(shè)備的部件一樣關(guān)鍵，有時甚至更重要。
模具材料
根據(jù)成型方法和模具使用周期（即要生產(chǎn)的產(chǎn)品數(shù)量）的不同，塑料成型模具要滿足不同的需求，模具可以由多種材料制成，甚至于可以使比較特殊的材料如紙張和石膏。然而，由于大多數(shù)成型過程需要高壓，通常還有高溫條件限制，金屬迄今為止時最重要的材料，其中剛才居首位。很多時候，模具材料的選擇不僅關(guān)系到性能和最佳性價比，還影響到模具的加工方法，甚至是整體設(shè)計。
The Injection Molding
The Introduction of Molds
The mold is at the core of a plastic manufacturing process because its cavity gives a part its shape. This makes the mold at least as critical-and many cases more so-for the quality of the end product as, for example, the plasticiting unit or other components of the processing equipment.
Mold Material
Depending on the processing parameters for the various processing methods as well as the length of the production run, the number of finished products to be produced, molds for plastics processing must satisfy a great variety of requirements. It is therefore not surprising that molds can be made from a very broad spectrum of materials, including-from a technical standpoint-such exotic materials as paper matched and plaster. However, because most processes require high pressures, often combined with high temperatures, metals still represent by far the most important material group, with steel being the predominant metal. It is interesting in this regard that, in many cases, the selection of the mold material is not only a question of material properties and an optimum price-to-performance ratio but also that the methods used to produce the mold, and thus the entire design, can be influenced.
