本(ben)實(shi)用新型涉及(ji)(ji)模具(ju)裝(zhuang)置技術(shu)領域(yu)，具(ju)體涉及(ji)(ji)一種接(jie)收透鏡(jing)光學注塑模具(ju)。

背景技術：

模(mo)(mo)(mo)(mo)具(ju)是一種在外(wai)力作用(yong)下(xia)使坯料(liao)成為有特(te)定(ding)形(xing)狀(zhuang)和尺寸的(de)制(zhi)件的(de)工具(ju)，它廣泛用(yong)于沖裁、模(mo)(mo)(mo)(mo)鍛、冷鐓、擠壓(ya)、粉末冶金件壓(ya)制(zhi)、壓(ya)力鑄造(zao)，以及(ji)工程塑料(liao)、橡膠、陶瓷等制(zhi)品的(de)壓(ya)塑或(huo)注塑的(de)成形(xing)加工中。模(mo)(mo)(mo)(mo)具(ju)具(ju)有特(te)定(ding)的(de)輪(lun)廓(kuo)或(huo)內(nei)腔(qiang)形(xing)狀(zhuang)，應(ying)用(yong)具(ju)有刃口(kou)的(de)輪(lun)廓(kuo)形(xing)狀(zhuang)可以使坯料(liao)按輪(lun)廓(kuo)線形(xing)狀(zhuang)發生分離，應(ying)用(yong)內(nei)腔(qiang)形(xing)狀(zhuang)可使坯料(liao)獲得相應(ying)的(de)立體(ti)形(xing)狀(zhuang)。模(mo)(mo)(mo)(mo)具(ju)一般(ban)包(bao)括(kuo)動模(mo)(mo)(mo)(mo)和定(ding)模(mo)(mo)(mo)(mo)兩個部(bu)分，二者可分可合。分開(kai)時(shi)取出制(zhi)件，合攏時(shi)使坯料(liao)注入模(mo)(mo)(mo)(mo)具(ju)型腔(qiang)成形(xing)。模(mo)(mo)(mo)(mo)具(ju)是精密工具(ju)，形(xing)狀(zhuang)復雜(za)，承受(shou)坯料(liao)的(de)脹力，對結構強度(du)、剛度(du)、表面硬度(du)、表面粗糙(cao)度(du)和加工精度(du)都有較高要(yao)求，模(mo)(mo)(mo)(mo)具(ju)生產(chan)的(de)發展(zhan)水平(ping)是機械制(zhi)造(zao)水平(ping)的(de)重要(yao)標(biao)志(zhi)之一。

一般光(guang)學(xue)產品都具有精密的光(guang)學(xue)鏡(jing)頭(tou)組件，而光(guang)學(xue)鏡(jing)頭(tou)大(da)致可(ke)分為(wei)球(qiu)面(mian)(mian)鏡(jing)頭(tou)與(yu)非球(qiu)面(mian)(mian)鏡(jing)頭(tou)，球(qiu)面(mian)(mian)透鏡(jing)加工(gong)工(gong)藝(yi)成(cheng)熟，成(cheng)本低，在激光(guang)準直光(guang)學(xue)系統中仍然被廣泛使(shi)用。相(xiang)對于(yu)球(qiu)面(mian)(mian)透鏡(jing)，非球(qiu)面(mian)(mian)透鏡(jing)具有更好的準直效果，可(ke)以得(de)到平(ping)行度(du)非常高(gao)的輸(shu)出(chu)光(guang)束。目前(qian)采(cai)(cai)用光(guang)學(xue)玻璃(li)的非球(qiu)面(mian)(mian)鏡(jing)主要采(cai)(cai)用金(jin)剛(gang)石(shi)切削或熱壓成(cheng)型的方法(fa)加工(gong)，其缺(que)點(dian)是(shi)加工(gong)成(cheng)本高(gao)且(qie)難(nan)以批(pi)量(liang)化加工(gong)，使(shi)用注塑技(ji)術生產的光(guang)學(xue)產品，具有低價，輕量(liang)，便(bian)于(yu)大(da)批(pi)量(liang)復制且(qie)具有高(gao)度(du)一致性。

申請號為201610008813.4的(de)中國發(fa)明專利公(gong)開了一種(zhong)新型光學模(mo)(mo)具，包(bao)括母(mu)(mu)模(mo)(mo)板(ban)和(he)公(gong)模(mo)(mo)板(ban)，所述母(mu)(mu)模(mo)(mo)板(ban)和(he)公(gong)模(mo)(mo)板(ban)中心底部設(she)(she)(she)置(zhi)有(you)(you)孔槽(cao)，所述孔槽(cao)內設(she)(she)(she)置(zhi)有(you)(you)墊塊(kuai)，所述孔槽(cao)下方的(de)母(mu)(mu)模(mo)(mo)板(ban)和(he)公(gong)模(mo)(mo)板(ban)內分(fen)別(bie)設(she)(she)(she)置(zhi)有(you)(you)模(mo)(mo)穴，所述母(mu)(mu)模(mo)(mo)板(ban)和(he)公(gong)模(mo)(mo)板(ban)內設(she)(she)(she)置(zhi)有(you)(you)模(mo)(mo)仁(ren)，所述母(mu)(mu)模(mo)(mo)板(ban)內部設(she)(she)(she)置(zhi)有(you)(you)灌嘴。該發(fa)明的(de)缺點是，結構(gou)復雜、模(mo)(mo)仁(ren)的(de)定位不(bu)夠準確，會影響(xiang)產品前后光學表面的(de)同(tong)心度。

分流道12設(she)置在動(dong)模仁10的(de)(de)表面，且(qie)分流道12垂直于型(xing)腔14設(she)置，本實用新型(xing)通過(guo)側澆口的(de)(de)結構設(she)計，改善了產品的(de)(de)留痕問題。

頂針71孔分別設(she)置在四個分流道(dao)12上，方便將(jiang)注塑好(hao)的產品頂出。

定模(mo)(mo)(mo)仁(ren)9和動模(mo)(mo)(mo)仁(ren)10均(jun)是通過淬火工(gong)藝(yi)處(chu)理的鋼材制(zhi)成，本(ben)實(shi)用新型(xing)的模(mo)(mo)(mo)具(ju)通過淬火工(gong)藝(yi)處(chu)理，使模(mo)(mo)(mo)具(ju)達(da)到高硬度，模(mo)(mo)(mo)具(ju)變形(xing)極小，從而可以制(zhi)造出高精密低(di)變形(xing)的光學產品。
