Description

200844056 九、發明說明 【發明所屬之技術領域】 本發明是關於需要精密加工的玻璃成型用模具之製造 方法’特別是關於能夠維持高精度模具形狀的玻璃成型用 模具之製造方法。 【先前技術】 於塑膠成型的技術領域，成型模具的精密加工技術已 經確立，能夠實現具有繞射光柵等微細形狀的光學元件的 量產。於該狀況，模具的製作是在不銹鋼形成的基材表面 施以化學Ni-P鍍層處理，接著，以金剛石刀具對該鍍層 進行精密加工藉此執行模具製作。 【發明內容】 但是，當上述相同的模具應用在玻璃成型時，會導致 化學Ni-P鍍層產生龜裂的問題。該現象產生的原因是在 於成型溫度。即，Ni-P鍍層於鍍層狀態是成爲非結晶（非 晶質）構造，但加熱至約270 °C以上時就會開始結晶化，此 時，鍍層會產生體積收縮，作用著拉伸應力以致鍍層產生 龜裂。 該問題的對策是選擇熱膨脹係數爲1 0 X 1 (Γ 6〜1 6 X 1 CT 6 (K —1)的 基材，施以鍍層後，以400 °C〜500 °C進行熱處理。但是， 即使基材的熱膨脹係數是配合Ni -P鍍層，但熱處理時， 結晶化造成的體積收縮還是只發生在鍍層，因此於鍍層還 -4- 200844056 是作用著大的拉伸應力，以致還是會有龜裂產生的狀況（ 例如參照日本特開平1 1 - 1 5 7852號公報）。 此外，模具使用中變高溫時，模具會產生塑性變形’ 因此也有無法維持高精度模具形狀的問題。 本發明是以提供一種可防止表面披覆層於成型溫度產 生龜裂的同時，能夠防止模具塑性變形，藉此能夠維持高 精度模具形狀的同時，能夠增加模具使用壽命的玻璃成型 用模具之製造方法爲目的。 爲了解決上述課題達成目的，本發明的玻璃成型用模 具之製造方法是構成如下述。 對碳爲〇.3wt%以上且2.7wt%以下，鉻爲13wt%以下， 需添加的添加物：鉬爲〇.5wt%以上且3wt%以下、釩爲 O.lwt%以上且5wt%以下、鎢爲lwt%以上且7wt%以下當中 至少滿足一項的鋼製素材進行淬火處理的同時，以4 0 0 °C 以上且6 5 0 °C以下進行回火處理藉此製成基材，於上述基 材的表面，形成由非晶質Ni-P合金形成的表面披覆層， 對其施以加熱處理，使上述表面披覆層轉變成N i和N i 3 P 的共晶組織。 對碳爲〇.3wt%以上且2.7wt%以下，鉻爲13wt%以下， 需添加的添加物··鉬爲〇.5wt%以上且3wt%以下、釩爲 O.lwt%以上且5wt%以下、鎢爲lwt%以上且7wt°/〇以下當中 至少滿足一項的鋼製素材進行淬火處理的同時’進行深冷 處理藉此製成基材，於上述基材的表面形成由非晶質N i _ P合金形成的表面披覆層’對其施以加熱處理’使上述表 -5- 200844056 面披覆層轉變成Ni和Ni3P的共晶組織。 【實施方式】 [發明之最佳實施形態] 第1圖是表示本發明一實施形態相關的玻璃成型用模 具之製造方法槪要流程圖。玻璃成型用模具之製造是以下 述作業步驟執行製造。 另，基材是採用碳爲〇.3wt%以上且2.7wt%以下，鉻爲 13wt%以下，需添加的添加物：鉬爲〇.5wt%以上且3wt%以 下、釩爲O.lwt%以上且5wt%以下、鎢爲lwt%以上且7wt% 以下當中至少滿足一項的鋼製素材。 對上述基材進行粗加工（S T 1)後，接著進行淬火•高 溫回火處理（ST2)。其次，在進行鍍前加工（ST3)後’利用 化學鍍使Ni-P合金形成的表面披覆層（鍍層）形成在基材 表面（ST4)。接著，對基材及表面披覆層進行加熱處理 (S T 5 )，使表面披覆層結晶化的同時，使基材轉變成回火 組織。其次，在進行基材精加工（ST6)及表面披覆層精加 工（ST7)後，對表面披覆層施以離模膜塗敷（ST8)。 本實施形態的製造方法中’基材是採用添加有Mo、 V、W已經提昇高溫硬度的鋼材，因此即使進行高溫回火 處理但還是能夠使表面披覆層不龜裂。其原因是，於淬火 處理隨後雖存在有多量殘留奧氏體，但進行高溫回火處理 時就會轉換成碳馬氏體及馬氏體的組織。 另，高溫回火處理的溫度需要在400 °C〜650 °C以下。 200844056 若高溫回火處理溫度比400 °C還低則殘留奧氏體的減低效 果不彰，但若超過650 °C則基材的軟化明顯。另外，也可 取代高溫回火處理改採用深冷處理。這是因爲深冷處理也 具有可使殘留奧氏體變成馬氏體的效果。 表面披覆層的形成，對於Ni-P合金例如是使用Ni-P 、Ni-P-B或Ni-P-W。該等的組織，於鍍層狀態是非晶質 或局部性非晶質，在約270 °C的加熱下，就轉變成完全結 晶化的Ni和Ni3P的混合組織。 加熱處理的溫度是需爲模具的使用溫度（即玻璃成型 溫度）以上。其理由是若加熱處理的溫度比模具的使用溫 度還低，則於使用中會產生尺寸變化，導致成型品尺寸精 度降低。若加熱處理溫度過高則會影響到鍍層面，因此加 熱處理溫度的上限爲700 °C程度。 其次，對基材採用上述成份鋼製素材的理由進行說明 。即，碳（C)含量需爲0.3wt%以上且2.7wt%以下。其理由 是若碳含量低於0.3 wt%時，則於回火處理中基材的體積收 縮量會太少。另一方面，若碳含量超過2.7wt%時，則基材 的體積收縮量雖足夠，但會產生韌性降低等弊害。 此外，鉻（Cr)含量需爲1 3wt%以下。其理由是若鉻含 量超過1 3 wt %則殘留奧氏體就變難以分解。另，針對鉻含 量的下限値，並無特別限制。 至於添加物鉬（Mo)、釩（V)、鎢（W)的條件，鉬需爲 0.5wt%以上且3wt%以下、釩需爲〇.lwt%以上且5wt%以下 、鎢需爲lwt%以上且7wt%以下。這是因爲該等添加物的 200844056 量若太少則基材的高溫硬度會不足恐怕於壓製加工壓力時 產生塑性變形。若添加量爲需求以上則成本會變高因此設 定上限。 對各種成份的基材進行化學鍍Ni-P製作出披覆有100 //m鍍層的模具，然對加熱處理中及成型中產生的龜裂數 及玻璃成型後基材是否產生塑性變形進行了調查。表1中 ，揭示著基材成份、回火溫度、龜裂產生率、有無塑性變 形的關係。試體7是比較例，其是使用習知進行熱處理的 塑膠成型用模具。此外，成型溫度全部都是5 5 0 °C。 表1基材成份及回火溫度、 龜裂產生率、有無塑性變形的 關係 基材 碳 鉻 組、飢、鶴 回火 龜裂 塑性 含量 含量 含量 溫度 產生率 變形 試體1 1.2 6.0 Μ Μ j\\\ 0/5 有 試體2 1.2 6.0 鉬：1.0,釩：1.0 Λ\ f Γ ΓΙΜ J\\\ 3/6 te 試體3 1.2 6.0 鎢：1.0,釩：1.0 Μ J V \Ν 1/5 Μ j\\\ 試體4 1.2 6.0 >fnr ιΙίΓ 580〇C 5/5 有 試體5 1.2 6.0 鉬：1.0,釩：1.0 580〇C 0/5 無 試體6 1.2 6.0 鎢：1.0,釩：1.0 580〇C 0/5 is： 試體7 0.3 14.0 釩：0.3 580〇C 5/5 ίκ y \ \\ 從表1中得知，根據本發明的製造方法所製成的模具（ 試體5、試體6)是沒有產生龜裂及塑性變形。 如以上所述，本實施形態相關的玻璃成型用模具之製 造方法及玻璃成型用模具，可防止表面披覆層於成型溫度 產生龜裂的同時，能夠防止模具塑性變形，因此能夠維持 -8 - 200844056 高精度模具形狀的同時，能夠增加模具使用壽命。 另外，本發明並不限於上述實施形態，例如基材及表 面披覆層的加熱處理也可在基材精加工及表面披覆層精加 工後進行。其他，只要不脫離本發明主旨範圍理所當然是 可加以各種變形實施。 [產業上之可利用性] 根據本發明時，可防止表面披覆層於成型溫度產生龜 裂的同時，能夠防止模具塑性變形，因此能夠維持高精度 模具形狀的同時，能夠增加模具使用壽命。 【圖式簡單說明】 第1圖爲表示本發明一實施形態相關的玻璃成型用模 具之製造方法槪要流程圖。 -9 -
