的成形用模具，是在固定模具與活動模具之任一方鏡面板 上，配設複製凹洞的壓模機（以下稱之為「複製用壓模機」）， 仿真光碟基板成形用模具則代替前述壓模機，而配設無凹洞 複製之壓模機（以下稱之為「匿影(blank)壓模機」）。因此成 形仿真光碟基板時，必須在成形用模具上加裝昂貴的匿影塵 模機。此外’成形用模具上也需設置壓模機支撐座與壓模機 更換裝置。再者，前魏髓模機是屬雜品，因此每當已 達到所預定成形次數時，就需執行更換作業。 相對之下，轉真辆基板*言，形成複製光碟基板貼 200818187 合面的鏡面板表面上則未配設匿影壓模機，而且也將鏡面板 表面視為膜腔形成面。但由不銹鋼所構成的鏡面板表面則有 實施精您、加工，該表面視為膜腔形成面，再成形仿真光碟基 板貼合面後，使會發生仿真光碟基板脫模不良的問題。為了 解決脱模不良的問題’因而採用藉由放電加工機等，將鏡面 板表面作成粗面的膜腔形成面，以消除脫模不良的問題。但 此時，鏡面板表面光潔度過粗後，會發生仿真光碟基板變成 _ 霧面玻璃狀而降低透明度的問題。而且與複製光碟基板貼合 後’即使在仿真光碟基板表面上印刷，印刷後的顏色也會變 成白色混濁狀，而有損光碟製品的外觀。基於上述理由的關 係，昔知的仿真光碟基板貼合面實際上都是藉由匿影壓模機 來成形。 特開平9-212916號公報（申請項目卜圖7乃至圖1〇)

機（以下稱之為「匿影(blank)壓模機」），固定面板18之 活動模具側表面，則連同其他閘門插件19之活動模具側表 面，各構成出膜腔形成面18a，19a。 、. 200818187 此外，正如圖1、圖2所示，被安裝於未出具在圖式上的 射出成形機之活動盤的活動模具13，是由活動模板22、被黏 合於活動模板22之固定模具侧面的活動内板23、在活動模板

面並未安裝匿影壓模機，活動鏡面板24之固定模具侧表面， 則連同前述内周膜腔形成塊26固定模具侧表面，各構成出膜 腔开》成面24a、26a。而且，活動鏡面板24膜腔形成面24a， 則形成出仿真光碟基板A貼合面的A1面。 本實施形態，在活動鏡面板24膜腔形成面24a上有塗佈 Tin (氮化鈦）（維克斯硬度Hvl000乃至Hvl4〇〇)，形成出厚 度l#m乃至10//m。而且，此活動鏡面板24的塗佈Tin在形 成塗佈膜後，用鑽石膏等進行精整加工。關於此塗佈Tin精 整加工，除了前述以外的方法，也可採用物理表面處理方法， 精整加工後的表面光潔度（十點平均光潔度）為 乃至0· 4//mRz。再者，Tin與DLC (類鑽石碳膜）相較之下， 摩擦係數及表面光潔度較大，因此有利於確保上述表面光潔 度。此外，活動鏡面板24之膜腔形成面24a上所塗佈的材料， 除了 Tin之外也可塗佈TiCN、TiCrN、TiALN等鈦氮化合物、 Sin、Si—等矽氮化合物、AIN、TaN、ZrN等其他氮化合物。 此外，還可塗佈SiC、TiC等碳化合物。此外，也可塗佈DLC (類鑽石碳膜）。關於上述塗佈方面，厚度約為lam乃至10 #m。此外，也可將WCC (塗佈碳化鎢）、硬質鉻等金屬鍍、氟 樹月旨（PTFE或PFA)厚度塗佈為30/zm乃至lmm。再者，前述 塗佈材，也可塗佈數層種類不同的塗佈材。這些塗佈則依據 Ρ1Φ、CVD、電漿CVD法等進行蒸鍍、陰極濺射環、金屬喷鍍、 電鍍塗佈等。而且，有時會進行精整加工，將表面光潔度加 200818187 工成〇· 〇5_z乃至〇. 4_Rz左右。再者，本實施形態，只 在活動鏡面板24膜腔形成面24a上執行前述塗佈，但也可在 固定鏡面板18媒腔形成面i8a上執行前述塗佈。再者，内周 膜腔形成塊26、閘門插件19膜腔形成面恤、版，也可執 行前述塗佈。 接下來’將卿本實制彡態伽成卵觀n的仿真光 =板A成形工程、仿真光碟基板A貼合複製光碟基板B以 ⑩ 製化光碟C的工程。首先，對於成形用模具11固定模具12 而言，活賴具13則形成出合模的膜腔14，且從未出具在圖 式上的射出裝置，將聚碳酸醋所構成之約35(rc的熔融樹脂射 出填充於前鑛腔14。毅，前舰轉脂只在膜腔14内進 行冷卻、固化與收縮。此時本實施形態是藉由塗佈Tjn的活 動鏡面板24之膜腔形成面24a，而在仿真光碟基板A上形成 出複製光碟基板B的貼合面A1。而且，結束冷卻、固化後， 驅動未出具在圖式上的模開閉裝置，讓活動模具13開模，成 餐 形仿真光碟基板A及未出具在圖式上的澆口，則受到突出插 梢29契合部29a及活動模具13所支撐。 此時，活動模具13開模前後，來自於脫模空氣通路31 的空氣’會遍及仿真光碟基板A貼合面、與活動鏡面板24 膜腔形成面24a之間，而促進從仿真光碟基板a活動模具13 進行脫模。此時，内周膜腔形成塊26上會形成出環狀突起 26B，並朝活動鏡面板24之膜腔形成面24a方向大量供應空 氣。關於這一方面，仿真光碟基板A在冷卻、固你時的收縮， 11 200818187 是朝内周側進行收縮，因此環狀突起26B之模開閉方向面、 與膜腔14内的仿真光碟基板A之間幾乎不出現間隙，且超過 一半的空氣，則朝活動鏡面板24之膜腔形成面24a侧進行供 應。再者，此時也可從活動鏡面板24外周侧，供應脫模用空 氣。 而且，仿真光碟基板A在脫模時，本實施形態上的活動 鏡面板24膜腔形成面24a，有塗佈被精整加工成表面光潔度 • 為0·05#·Κζ乃至0.4/zmRz的Tin，因此相較於精整加工成 〇· 〇2/zmRz乃至〇· 〇3#mRz，而由昔知的不銹鋼所構成的活動 鏡面板表面順利脫模仿真光碟基板A。此外，相較於昔知放電 加工機，是由不銹鋼所構成的活動鏡面板表面，粗面加工成 ΙΟ/zmRz乃至5.0/zmRz，讓仿真光碟基板A貼合面呈霧面玻 璃狀，而本實施形態的仿真光碟基板A表面不會形成霧面玻 璃狀’且得以維持仿真光碟基板A的透明度。再者，活動鏡 面板24膜腔形成面24a有塗佈Tin，除了脫模性佳之外，成 _ 形時也可減少活動鏡面板24之膜腔形成面24a的摩耗。但因 長期間成形而摩耗膜腔形成面24a時，也可重新將活動鏡面 板24之膜腔形成面24a精整加工成上述表面光潔度。此外， 為了修正活動鏡面板24的摩耗對策、與兩模具12、13的尺 寸誤差，也可在活動鏡面板24、活動内板23内面，放入填缝 片與隔板。 脫模的前述仿真光碟基板A ’是藉由未出具在圖式上的取 出機，從成形光碟基板機進行吸附、移出。雨且被移出的仿 12 200818187 真光碟基板A，是藉由複製凹洞的壓模機（以下稱之為「、— 用壓模機」），所配設之未出具在圖式上的成形用模具而=形 的複製光碟基板B、經過鋁蒸鍍等工程後所貼合而成。此時^ 則如圖2所示，複製光碟基板b的凹洞，則在被複製的複製 面B1上貼合仿真光碟基板A貼合面A1。而且，透過内周壓模 機支撐座爪部的突起讓複製光碟基板B上所形成的環狀凹部 B2、及藉由内周膜腔形成塊26之環狀突起2册而在仿真光碟 基板A上所形成的環狀凹部A2,在相同位置上進行對置。因 此貼合時，被塗佈於複製面B1的黏著劑D，並不會從前述環 狀凹部A2、B2而流往内周孔A3、b3。而且，其後的仿真光碟 基板A貼合面，則被印刷於相反侧的印刷面M (本實施形態 上，是藉由固定鏡面板18膜腔形成面I8a所成形的面），而 形成出擁有相反於複製光碟基板B複製面B1之讀取面β4的 DVD磁碟。此時，印刷顏色會變成白濁狀，而不影響外觀。 再者’本發明已針對藉由上述塗佈的活動鏡面板24之膜 腔形成面24a，形成仿真光碟基板a貼合面A1進行敘述，但 也可成形印刷面A4。關於藉由膜腔形成面24a所成形的仿真 光碟基板A之面，其貼合面A1比起印刷面A4可望能在後續 工程上提升印刷性。此外，設置上述表面光潔度膜腔形成面 24a的模具，由於仿真光碟基板a是受到活動模具13所支撐 而開模，因此為了提升開模後的脫模性，設置於活動模具13 上則最具效果。但，本發明並未受限於上述實施例，也可塗 佈固定模具的固定鏡面板膜腔形成面，以藉由該艤腔形成面 13 200818187 形成出仿真光碟基板A的貼合面A1。此外，被仿真光碟基板 A貼合的複製光碟基板β的成形模具方面’前述複製用壓模機 也可配設於固定模具。再者，也可同時成形2片以上仿真光 碟基板而設置數個膜腔。 接下來，將說明本發明第二實施形態上的光碟基板成形 賴具4卜圖3表示本發明第二實施形態的光碟基板成形用 模具41 #重要部位剖面圖。如第二實施形態所示，是以數個 眷酿44、45同時成形出’讓複製光碟基板Β及該複製光碟基 板Β上所貼合的仿真光碟基板a，形成於固定模具犯與活動 模具43之間的光碟基板成形用模具41。再者，在此省略說明 同於上述實施形態的部分。 第二實施形態之光碟基板成形用模具41的固定模具 42，有内置熱流道(h〇t runner)機構46，並配設了接觸未出 具在圖式上的射出裝置喷嘴的噴嘴接觸部4?，這是藉由加熱 器_前述嘴嘴接觸部47上連接加熱連座48。而且，溶融樹 ® 脂通路49則用前述連座48内部進行分岐，再將熔融樹脂供 應到前述膜腔44、45。而且，連座48兩侧則有連接透過相同 加熱器所加熱的噴嘴50、50，噴嘴5〇、5〇被連接於各澆口套 51、 51。而且，前述澆口套51、51外周上則配設了閘門插件 52、 52 ’前述閘門插件52、52外周上則配設形成冷卻溝的固 定鏡面板53、53。而且，前述固定鏡面板53、53的活動模具 側表面，皆未配設複製用壓模機或匿影壓模機，前述表面則 形成出膜腔形成面53a、53a。 200818187 此外，第二實施形態的活動模具43，是在一方膜腔44 侧上配設只有活動鏡面板54的複製用壓模機55 (厚度0· 2刪 鎳製複製用壓模機）。而且前述複製用壓模機55，是藉由外周 壓模機支撐座56、内周壓模機支撐座57、及未出具在圖式上 的壓模機吸引手段的空氣吸引方式受到前述活動鏡面板54表 面所支撐。此外，内周壓模機支撐座57内周上，則有配設固 定套管58，其内周則有配設喷射器59、公刀60、及突出插梢 61。而且，另一方膜腔45侧面的活動鏡面板62上，並未配 設複製用壓模機55或匿影壓模機，而讓活動鏡面板62固定 模具侧面形成出膜腔形成面62a。前述活動鏡面板之膜腔 形成面62a，屬於形成仿真光碟基板A貼合面A1的面，且有 執行上述實施形態般的塗饰Tin，而提升前述貼合面A1的脫 模性。此外，内周膜腔形成塊63、脫模空氣通路64等構成上 也同於上述實施形態。再者，除了在膜腔形成面62a上塗佈 Tin之外，也可塗佈至少一種dlc、氮化合物、碳化合物及碳 化鎢，關於這一點也是相同。 接下來，將說明第二實施形態之光碟基板成形用模具41 的成形。對於固定模具42而言，活動模具43會藉由合膜而 形成出可變容積的二個膜腔44、45。此時，成形複製光碟基 板β的膜腔44上，則有配置厚度〇· 2mm複製用壓模機55,且 依據前述壓模機55的厚度，是讓固定鏡面板53之膜腔形成 面53a、與活動鏡面板54之固定模具侧表面之間的距離，比 成形仿真光碟基板A的膜腔45還長的方式所譟計而成。再 15 200818187 者’關於第二實施形態方面，為了調整藉由膜腔44、45所成 形的光碟基板A、B板厚而***填縫片或隔板、或個別控制左 右喷嘴50、50溫度’以調整對溶融樹脂膜腔44、45的射出 填充量等。而且，藉由從未出具在圖式上的射出裝置，經過 前述熱流道機構而射出填充的熔融樹脂，透過前述二個膜腔 44、45以同時成形光碟基板A、B。其後當活動模具43開模 後，仿真光碟基板A與複製光碟基板B，皆受到活動模具43 所支撐。而且，接下來在執行光碟基板A、B脫模時，關於仿

Description of the Invention: [Technical Field] The present invention relates to a disk substrate formed by a pit (Pit) formed by a cavity formed between a fixed mold and a movable mold, and a sticker The optical disk substrate molding die of the dummy optical disk substrate on which the recess is not formed. [Prior Art] The optical disk represented by the DVD-5 is a cavity formed by a fixed mold and a movable mold, and each of which is formed by a disk (reproduced by a tip) (hereinafter referred to as a disk) The "replicating optical disk substrate" and the dummy optical disk substrate (hereinafter referred to as "simulation optical disk substrate") in which the concave holes are not copied are manufactured by laminating the copying optical disk substrate and the dummy optical disk substrate. Further, in the molding of the optical disk substrate of the optical disk, the optical disk substrate molding die described in the above-mentioned Patent Document 1 is used for injection molding. The basic structure of the mold for molding a virtual disk substrate described in Patent Document 1 is almost the same as the structure for replicating the mold for molding an optical disk substrate. In short, the molding die for copying the optical disk substrate is a molding machine (hereinafter referred to as a "copying molding machine") for disposing a concave cavity on one of the fixed mold and the movable mold, and the artificial optical disk substrate is simulated. In place of the above-mentioned molding machine, a molding die is provided with a molding machine without a cavity (hereinafter referred to as a "blank molding machine"). Therefore, when simulating the optical disk substrate, it is necessary to install an expensive shadow dusting machine on the molding die. Further, a molding machine support and a press changing device are also required on the forming mold. Furthermore, the pre-Wei-medullary molding machine is a groceries, so replacement work is required whenever the predetermined number of forming times has been reached. In contrast, the true substrate is formed, and the copying of the optical disk substrate is formed. The surface of the mirrored panel of the 200818187 is not equipped with a shadowing molding machine, and the surface of the mirror panel is also regarded as a cavity forming surface. However, the surface of the mirror panel made of stainless steel is finely processed and processed. This surface is regarded as the cavity forming surface, and after the embedding of the mating surface of the emulating disc substrate, the problem of defective demolding of the emulating disc substrate occurs. In order to solve the problem of mold release failure, a surface of the mirror surface is formed into a rough surface by a discharge machine or the like to eliminate the problem of mold release failure. However, at this time, when the surface finish of the mirror panel is too thick, the problem that the artificial optical disk substrate becomes _ matte glass shape and the transparency is lowered occurs. Moreover, even after printing on the surface of the emulated disc substrate, the printed color becomes white and turbid, which detracts from the appearance of the optical disc product. For the above reasons, the mating surface of the simulated optical disk substrate is actually formed by a shadow molding machine.

The annular cavity formed on the outer peripheral portion of the membrane cavity forming surface of the mold side surface is fixed. 3. Mirroring the effect of the prior art. The mirror panel of the mold for forming an optical disk substrate of the present invention is a film cavity formed between a fixed mold and a movable mold, and a disc substrate and a sticker which are reproduced by the concave hole are formed. A movable mold is disposed in the movable mold in the mold for forming the optical disk substrate on which the dummy optical disk substrate is not copied, and the dummy optical disk substrate has a bonding surface on which the optical disk substrate copied by the concave hole is formed.
