模具，工業(yè)生產(chǎn)上用以注塑、吹塑、擠出、壓鑄或鍛壓成型、冶煉、沖壓等方法得到所需產(chǎn)品的各種模子和工具。簡(jiǎn)而言之，模具是用來(lái)制作成型物品的工具，這種工具由各種零件構(gòu)成，不同的模具由不同的零件構(gòu)成。它主要通過(guò)所成型材料物理狀態(tài)的改變來(lái)實(shí)現(xiàn)物品外形的加工。素有“工業(yè)之母”的稱號(hào)。在外力作用下使坯料成為有特定形狀和尺寸的制件的工具。用于沖裁、模鍛、冷鐓、擠壓、粉末冶金件壓制、壓力鑄造，以及工程塑料、橡膠、陶瓷等制品的壓塑或注塑的成形加工中。模具具有特定的輪廓或內(nèi)腔形狀，應(yīng)用具有刃口的輪廓形狀可以使坯料按輪廓線形狀發(fā)生分離（沖裁）。應(yīng)用內(nèi)腔形狀可使坯料獲得相應(yīng)的立體形狀。模具一般包括動(dòng)模和定模（或凸模和凹模）兩個(gè)部分，二者可分可合。分開(kāi)時(shí)取出制件，合攏時(shí)使坯料注入模具型腔成形。模具是精密工具，形狀復(fù)雜，承受坯料的脹力，對(duì)結(jié)構(gòu)強(qiáng)度、剛度、表面硬度、表面粗糙度和加工精度都有較高要求，模具生產(chǎn)的發(fā)展水平是機(jī)械制造水平的重要標(biāo)志之一。模具種類很多根據(jù)加工對(duì)象和加工工藝可分為：①加工金屬的模具。②加工非金屬和粉末冶金的模具。包括塑料模(如雙色模具、壓塑模和擠塑模等)、橡膠模和粉末冶金模等。根據(jù)結(jié)構(gòu)特點(diǎn)。</p><div
