主要元件

1. 標(biao)準(zhun)部品及規(gui)格模具用(yong)(yong)(yong)(yong)標(biao)準(zhun)規(gui)格之選擇方(fang)法zui好考量下(xia)列事項(xiang)：(A).使(shi)用(yong)(yong)(yong)(yong)的規(gui)格內容不受(shou)限制時，zui好采用(yong)(yong)(yong)(yong)zui高層者(zhe)。(B).原則上采用(yong)(yong)(yong)(yong)標(biao)準(zhun)數。(C).模具標(biao)準(zhun)部品無此尺(chi)寸時，漢陽塑膠(jiao)模具，采用(yong)(yong)(yong)(yong)zui接近者(zhe)再進行加(jia)工(gong)。

2.沖頭(tou)(tou)之設計沖頭(tou)(tou)依其功能可(ke)大致(zhi)分為三大部(bu)(bu)(bu)(bu)(bu)份：(A).加工(gong)材料之刃部(bu)(bu)(bu)(bu)(bu)先(xian)端（切刃部(bu)(bu)(bu)(bu)(bu)，塑膠(jiao)模具加工(gong)，其形(xing)(xing)(xing)狀(zhuang)(zhuang)有不規則(ze)形(xing)(xing)(xing)、方(fang)形(xing)(xing)(xing)、圓形(xing)(xing)(xing)等(deng)）。(B).與沖頭(tou)(tou)固(gu)定(ding)板接(jie)觸部(bu)(bu)(bu)(bu)(bu)（固(gu)定(ding)部(bu)(bu)(bu)(bu)(bu)或(huo)柄(bing)部(bu)(bu)(bu)(bu)(bu)，其斷面形(xing)(xing)(xing)狀(zhuang)(zhuang)有不規則(ze)形(xing)(xing)(xing)、方(fang)形(xing)(xing)(xing)、圓形(xing)(xing)(xing)等(deng)）。(C).刃部(bu)(bu)(bu)(bu)(bu)與柄(bing)部(bu)(bu)(bu)(bu)(bu)之連結部(bu)(bu)(bu)(bu)(bu)份 （中間部(bu)(bu)(bu)(bu)(bu)）。沖頭(tou)(tou)各部(bu)(bu)(bu)(bu)(bu)份之設計基準分別從 (A).切刃部(bu)(bu)(bu)(bu)(bu)長度，(B).切刃部(bu)(bu)(bu)(bu)(bu)之研磨方(fang)向，(C).沖頭(tou)(tou)之固(gu)定(ding)法及柄(bing)部(bu)(bu)(bu)(bu)(bu)之形(xing)(xing)(xing)狀(zhuang)(zhuang)等(deng)方(fang)面簡述(shu)之。

塑(su)料模(mo)具(ju)是塑(su)料加工工業中(zhong)和(he)(he)塑(su)料成型(xing)(xing)機配套(tao)，賦予(yu)塑(su)料制(zhi)品(pin)以完整(zheng)構(gou)型(xing)(xing)和(he)(he)精l確(que)尺寸的工具(ju)。由于(yu)塑(su)料品(pin)種(zhong)(zhong)和(he)(he)加工方法(fa)繁多，塑(su)料成型(xing)(xing)機和(he)(he)塑(su)料制(zhi)品(pin)的結(jie)(jie)構(gou)又繁簡不一，塑(su)膠模(mo)具(ju)制(zhi)造，塑(su)料模(mo)具(ju)的種(zhong)(zhong)類和(he)(he)結(jie)(jie)構(gou)也是多種(zhong)(zhong)多樣的。

模具設(she)(she)(she)計和(he)制造與塑料加(jia)工有密切關系。塑料加(jia)工的成(cheng)敗，很大程度上取決于(yu)模具設(she)(she)(she)計效果和(he)模具制造質量(liang)，而(er)塑料模具設(she)(she)(she)計又以正確的塑料制品設(she)(she)(she)計為基礎(chu)。

加工種類

1．粗加(jia)工粗加(jia)工策略需要根(gen)據毛(mao)坯的類型(xing)和模具型(xing)面(mian)的情況而定(ding)。如果(guo)毛(mao)坯為鍛件(jian)或鋼(gang)件(jian)，那么粗加(jia)工zui好(hao)先選用(yong)區域清(qing)除模型(xing)加(jia)工，將毛(mao)坯的大(da)部分余量去(qu)除掉，得到均(jun)勻的毛(mao)坯余量，為后序加(jia)工提供(gong)方便。

2．半精(jing)加(jia)工(gong)半精(jing)加(jia)工(gong)的主要目的是(shi)(shi)保證(zheng)精(jing)加(jia)工(gong)時余量均勻，塑膠(jiao)模具(ju)批發，zui常用(yong)的方法是(shi)(shi)先(xian)算出殘留材料的邊界輪廓（參考刀具(ju)未加(jia)工(gong)區(qu)域(yu)的三(san)維輪廓），然后選用(yong)較小的刀具(ju)來加(jia)工(gong)這些三(san)維輪廓區(qu)域(yu)，而不(bu)用(yong)重新(xin)加(jia)工(gong)整(zheng)個模型。

3．局(ju)部(bu)精加(jia)工(gong)(gong)(gong)局(ju)部(bu)精加(jia)工(gong)(gong)(gong)一般是(shi)指清(qing)(qing)角(jiao)加(jia)工(gong)(gong)(gong)。清(qing)(qing)角(jiao)加(jia)工(gong)(gong)(gong)應采用多次加(jia)工(gong)(gong)(gong)或系列(lie)刀具(ju)從大(da)到小的加(jia)工(gong)(gong)(gong)方(fang)法。
