201208851 圖面說明中相同元件是用相同圖號，省略重複的說明。圖 面的尺寸比例，爲了方便說明會有較誇張且與實際比例不 同的情況。 通過樹脂成形品的製造方法的實施方式，來說明本發 明，該樹脂成形品是適用於安裝面板、車門面板、控制面 板等的車輛用內裝零件。 參考第1圖及第2圖，實施方式的樹脂成形品50， 是一體化形成有：在表面形成有裝飾面67的裝飾構件60 、作成重疊於裝飾構件60的表層的透明樹脂層70、以及 作爲射出到裝飾構件60的背面69的芯材的樹脂材料80 。裝飾構件60，具備有：將外周部分65朝向背面69側 彎折所形成的第一肋部6 1。透明樹脂層7 0，具備有：將 外周部分75朝向裝飾構件60的背面69側彎折形成的第 二肋部72。在裝飾構件60所具備的第一肋部61，將透明 樹脂層70所具備的第二肋部72重疊配置。裝飾構件60 的第一肋部61的端面63，是藉由芯材用的樹脂材料80 所覆蓋。是隔介著芯材用的樹脂材料80將裝飾構件60與 透明樹脂層70接合。 針對構成樹脂成形品的各構件加以說明。 參考第2圖（A)，在本實施方式，裝飾構件60，是 利用平板狀的突板的木質裝飾構件，藉由留下突板原本具 備的木紋及顏色而形成圖樣。藉由具有該圖樣的表面而構 成裝飾面67。圖中雖然省略，而在裝飾構件60的背面69 ，安裝有用來提高剛性的背襯材。 201208851 參考第2圖（B )，在透明樹脂層70是利用形成爲平 板狀的PMMA樹脂（聚甲基丙烯酸甲酯）。要在透明樹 脂層70轉印後述的鏡面的情況，透明樹脂層70，將裝飾 構件60的裝飾面賦予光澤，發揮使目視裝飾面67時的美 觀性提升的功能。當將後述的粗糙面轉印到透明樹脂層 70的情況，透明樹脂層70，會發揮：當目視裝飾面67時 的質感或碰觸透明樹脂層70時的觸感的功能》 構成透明樹脂層70的樹脂材料，並不僅限定於 PMMA樹脂，也可利用其他的熱可塑性樹脂等。例如，甲 基丙烯酸樹脂、ABS樹脂、AS樹脂、離子鍵樹脂、聚碳 酸酯等。即使是舉例，尤其希望選擇光線穿透率8 0 %以 上的樹脂材料。是因爲要能清楚地目視到附加在裝飾面 6 7的圖樣。 參考第3圖（A)，在射出成形之前，將裝飾構件60 與透明樹脂層70暫時接合製作出預備成形體90。暫時接 合是利用由熱可塑性樹脂所構成的透明的黏接劑95 (也 參考第4圖（A ))。隔介在裝飾面67與透明樹脂層70 之間的黏接劑95，能發揮當目視裝飾面67時使折射率變 大的功能。藉此，在裝飾面67，可表現突板所具備的木 頭獨特的光澤或深度。在暫時接合之前，將透明的黏接劑 95預先塗佈在裝飾面67，也可準備成浸透於裝飾構件60 的內部的狀態。 透明樹脂層70的厚度w2，是形成爲較裝飾構件60 的厚度wl更大。在用來在預備成形體90形成肋部61、 201208851 72所進行的彎曲成形，是用來防止在裝飾構件60產生 紋。參考第4圖針對用來防止裝飾構件60的裂紋的原 加以說明。 參考第4圖，對於預備成形體90的彎曲成形，是 用具備有衝頭41及衝模43的彎曲成形用模具40來進 。當使彎曲成形用模具40的衝頭41接近裝飾構件60 壓時，在預備成形體90的內表面側主要產生壓縮應力 以第4圖（B)中的箭頭a表示），在預備成形體90的 表面側主要產生拉伸力（以第4圖（B)中的箭頭b表 )。當壓縮力與拉伸力兩者對於裝飾構件60大幅作用 ，則裝飾構件60容易產生裂紋。 因此，如第4圖（A)所示，將透明樹脂層70的 度w2形成爲大於裝飾構件6 0的厚度w 1，使作爲裝飾 件60的上面的裝飾面67位於較預備成形體90的厚度 向的中立軸c更靠近衝頭4 1側。藉由該配置方式，則 使更大的拉伸力作用於：位於預備成形體90的外表面 的透明樹脂層7 0，而可使作用於：位於預備成形體9 0 內表面側的裝飾構件6 0的拉伸力減低。對於裝飾構件 ’變成是壓縮力主要作用，所以能適當地防止產生裂紋 由於適當地防止裝飾構件6 0產生裂紋，所以可將圓角 分的曲率設定得較大來進行彎曲成形。 裝飾構件60的厚度w !，雖然沒有特別限定，例如 設定爲〇.15mm〜l.〇mm左右。而透明樹脂層70的厚 w2，例如可設定爲〇.5mm〜3.0mm左右。在該尺寸的範 裂 理 利 行 按 ( 外 示 時 厚 構 方 會 側 的 60 〇 部 可 度 圍 -9- 201208851 內’可藉由使透明樹脂層70的厚度w2比裝飾構件60的 厚度w1更厚，則可適當地防止：當彎曲成形時裝飾構件 60產生裂紋。 參考第1圖’在芯材用的樹脂材料80利用ABS樹脂 。在芯材用的樹脂材料8 0也可利用A B S樹脂以外的材料 。例如’在樹脂成形的芯材，可適當利用：—般所利用的 其他熱可塑性樹脂、及將複數的熱可塑性樹脂等混合的材 料。 在芯材用的樹脂材料8 0，利用：具備有與裝飾構件 60的顏色類似的顏色的材料較佳。是爲了防止：因爲時 間變化等，而芯材用的樹脂材料8 0染色到裝飾構件6 0的 裝飾面67的情況導致美觀性降低。 針對實施方式的樹脂成形品的製造裝置來說明。 參考第5圖〜第7圖，樹脂成形品的製造裝置5，具 備有成形模10，該成形模10是由第—模11與第二模21 所構成’該第一模1 1具備有：將透明樹脂層7 0面向合倂 配置的第一成形面12，該第二模21具備有：藉由與第一 模1 1的模具緊固而在裝飾構件6 0的背面6 9側形成膜腔 33的第二成形面22(參考第6圖）。在第二模21設置有 :用來將溶融的芯材用的樹脂材料8 0導引到模腔3 3的澆 口部 3 1。 成形模10的第二模21’設置成相對於第一模11可 自由接近分離移動。藉由使第二模21朝第一模11接近移 動’則可進行成形模1 0的模具緊固。藉由使第二模2 1從 -10- 201208851 第一模1 1離開移動，則可進行成形模1 0的模具開啓。 裝飾構件60及透明樹脂層70，是以暫時接合狀態配 置於成形模1〇(參考第5圖）。是以將裝飾構件60與透 明樹脂層70設置在成形模1 〇的狀態進行模具緊固，而形 成膜腔33(參考第6圖）。模具緊固之後，從澆口部31 將熔融的芯材用的樹脂材料80朝向模腔33內射出。 在成形模1 〇利用模具，在第一模1 1的第一成形面 12，藉由實施鏡面加工，賦予鏡面（也就是說，第一成形 面12具有鏡面性質）。藉由設定芯材用的樹脂材料80的 射出溫度及射出壓力，則可將第一成形面1 2的鏡面轉印 到透明樹脂層70。例如將芯材用的樹脂材料80的溫度設 定成較透明樹脂層70的玻璃轉移溫度更高的溫度，來進 行射出。則可使透明樹脂層70軟化，且利用射出壓力將 透明樹脂層70緊壓於第一模1 1的第一成形面1 2。則將 經過鏡面加工的第一成形面1 2的表面形狀轉印到緊壓的 透明樹脂層7 0。藉此，可將透明樹脂層7 0的外表面形成 爲平滑且有光澤的表面。 第一模1 1的第一成形面1 2的表面形狀，並沒有特別 限定，也可藉由在第一成形面12實施粗糙面加工，使第 —成形面12具有粗糙面（也就是說，第一成形面12具有 粗糙面性質）。該粗糙面，所包含的表面形狀是具有用來 形成例如皮革、锻紋表面抛光、木紋、布紋等的皴折圖樣 的細微凹凸。藉此，則能將透明樹脂層70的外表面形成 爲例如具有皮革、緞紋表面拋光、木紋、布紋等的皺折圖 -11 - 201208851 樣的表面。 這裡例如當將玻璃轉移溫度爲110°C左右的PMMA樹 脂利用爲透明樹脂層70的材料時，在芯材用的樹脂材料 80例如可利用：可將熔融溫度設定在26(TC左右的ABS 樹脂。在該情況，藉由將射出壓力設定在40MPa左右， 則可將第一成形面1 2的表面形狀適當地轉印到透明樹脂 層70的外表面。 參考第4圖，樹脂成形品的製造裝置5，具有用來對 於裝飾構件60及透明樹脂層70進行彎曲成形的彎曲成形 用模具40。藉由彎曲成形用模具40來賦形處理成爲近似 於製品形狀的預定形狀。 彎曲成形用模具40具有：用來載置裝飾構件60及透 明樹脂層70的衝模43、以及設置成可對於衝模43自由 接近分離移動的衝頭41。 彎曲成形，是將裝飾構件60及透明樹脂層70載置於 衝模43，使衝頭41接近於衝模43來進行。如圖示，也 可對裝飾構件60及透明樹脂層70兩者同時進行彎曲成形 ，也可對於裝飾構件60或透明樹脂層70的其中一方來進 行彎曲成形。 接著針對實施方式的樹脂成形品的製造方法來說明。 參考第3圖（A )，將透明樹脂層70重疊到裝飾構 件60的裝飾面67。此時，藉由預先塗佈在裝飾面67的 透明的黏接劑95將其暫時接合，來製作預備成形體90。 接著，進行賦形處理成近似於製品的形狀的彎曲成形 -12- 201208851 參考第4圖（A)，將預備成形體90載置於彎曲成 形用模具40的衝模43。 參考第4圖（B) ’使衝頭41相對於衝模43接近移 動，來按壓預備成形體90。將構成預備成形體9〇之裝飾 構件60·的外周部分65及透明樹脂層70的外周部分75分 別彎折。將作爲裝飾構件60的上面的裝飾面67，設定在 :相較於預備成形體90的厚度方向的中立軸c更靠近衝 頭41側，則彎曲成形時可使作用於裝飾構件6 0的拉伸力 減低。藉此，可適當地防止在裝飾構件6 0產生裂紋》 參考第3圖（B)，在裝飾構件60形成有朝背面69 側彎折的第一肋部61。在透明樹脂層70形成有與第一肋 部61重疊的第二肋部72。 接著進行用來射出芯材用的樹脂材料80的射出成形 〇 參考第5圖，將預備成形體90配置在成形模10。將 透明樹脂層70面向第一模1 1的第一成形面1 2合倂配置 。在將裝飾構件60與透明樹脂層70暫時接合而一體化的 狀態，進行朝向成形模1 〇的配置作業，所以能容易進行 定位作業，能使作業效率提升。 參考第6圖，在配置好預備成形體90之後，進行成 形模1 0的模具緊固。藉由模具緊固而在裝飾構件60的背 面69側形成模腔33。在模具緊固狀態，在裝飾構件60 的第一肋部61的端面63與透明樹脂層70的第二肋部72 -13- 201208851 之間區劃形成空間S。 使熔融的芯材用的樹脂材料8 〇從澆口部3 1朝向模腔 3 3內射出。將芯材用的樹脂材料8〇射出到裝飾構件6〇 的背面69。由於防止了流動的高溫的樹脂材料8〇接觸於 裝飾面67’所以能適當地防止在裝飾面67產生碳化或變 色。 藉由來自芯材用的樹脂材料80的熱量讓透明樹脂層 7 〇軟化。伴隨著芯材用的樹脂材料8 〇的射出而對於軟化 的透明樹脂層70賦予射出壓力。將透明樹脂層7〇緊壓在 :經過鏡面加工或粗糙面加工（或具有鏡面性質或粗糙面 性質）的第一模11的第一成形面12，將第一成形面12 的表面形狀轉印到透明樹脂層70。藉此因應於第一成形 面12的表面形狀’而將透明樹脂層70的外表面成形爲： 平滑且有光澤的表面或具有皮革、緞紋表面拋光、木紋、 布紋等的圖樣的表面。 參考第7圖，將芯材用的樹脂材料80充塡到模腔33 內。此時’在裝飾構件6 0的第一肋部61的端面6 3與透 明樹脂層70的第二肋部72之間區劃形成的空間s內，也 充塡有芯材用的樹脂材料80。以芯材用的樹脂材料80覆 蓋裝飾構件60的第一肋部61的端面63將其隱蔽。藉此 ’可防止從第一肋部6 1的端面63吸收濕氣。能長期維持 樹脂成形品5 0的製品品質。 充塡到區劃形成的空間s內的芯材用的樹脂材料8 0 與透明樹脂層70接觸。透明樹脂層70熔融，在與芯材用 -14- 201208851 的樹脂材料8〇的界面一邊混合一邊緊貼。藉由芯材用的 樹脂材料80使裝飾構件60與透明樹脂層70接合。將裝 飾構件60保持在內部，則能形成：維持著賦形處理過的 製品形狀的樹脂成形品5 〇。在將成形模1 〇進行模具開啓 之後’將樹脂成形品50取出。 藉由進行以上的各步驟，則可取得：讓形成有裝飾面 67的裝飾構件60、將裝飾構件60的裝飾面67覆蓋的透 明樹脂層70、芯材用的樹脂材料80 —體化的樹脂成形品 5〇 (參考第1圖）。 如上述，藉由本實施方式的樹脂成形品5 0的製造方 法’將與裝飾構件60的裝飾面67重疊的透明樹脂層70 ，面向第一模11的第一成形面12合倂配置，將芯材用的 樹脂材料8 0射出到裝飾構件60的背面69，則能防止： 熔融的芯材用的樹脂材料80接觸於裝飾面67。則可防止 伴隨射出成形所產生的裝飾面67的碳化或變色，而可提 升樹脂成形品5 0的外觀品質。則可節省在裝飾面6 7塗佈 耐熱塗料等的準備步驟’所以可提升樹脂成形品5 0的生 產性，能夠減低製造成本。 在將裝飾構件6 0與透明樹脂層7 0暫時接合而一體化 的狀態，進行朝向成形模1 〇的配置作業，所以能容易進 行定位作業，能使作業效率提升。 將透明樹脂層70的厚度w2形成爲大於裝飾構件60 的厚度wl，將作爲裝飾構件60的上面的裝飾面67，設 定在：相較於預備成形體90的厚度方向的中立軸c更靠 -15- 201208851 近衝頭4 1側。則彎曲成形時可使作用於裝飾構件60的拉 伸力減低。藉此，可適當地防止在裝飾構件6 0產生裂紋 〇 在裝飾構件60的第一肋部6 1的端面63與透明樹脂 層70的第二肋部72之間區劃形成的空間s內，充塡有芯 材用的樹脂材料80。能隔介著所充塡的芯材用的樹脂材 料80將裝飾構件60與透明樹脂層70接合。以芯材用的 樹脂材料80覆蓋裝飾構件60的第一肋部61的端面63將 其隱蔽。藉此，可防止從第一肋部61的端面63吸收濕氣 。能長期維持樹脂成形品50的製品品質。 則可取得：藉由芯材用的樹脂材料80來覆蓋裝飾構 件60的第一肋部61的端面63，並且隔介著芯材用的樹 脂材料80將裝飾構件60與透明樹脂層70接合的樹脂成 形品5 0。 (變形例） 接著針對上述實施方式的變形例來說明。在本變形例 ，並不將裝飾構件60與透明樹脂層70暫時接合，而進行 彎曲成形步驟以及朝向成形模1 0的配置作業。在該要點 ，是不同於：對於暫時接合的預備成形體90進行彎曲成 形步驟以及朝成形模10的配置作業的上述實施方式。與 上述實施方式相同的構件用相同圖號，而省略局部說明。 參考第8圖（A)，準備裝飾構件60。對裝飾構件 60實施彎曲成形而進行賦形處理。 -16- 201208851 參考第8圖（B )，準備透明樹脂層7 0。透明樹脂層 70，例如能利用透明樹脂製造用的成形模來製造，該成形 模具備有··實施過鏡面加工的成形面。在圖示例子，藉由 利用透明樹脂製造用的成形模的射出成形，預先形成第二 肋部72。 參考第9圖，在將成形模1 0進行模具開啓的狀態， 配置透明樹脂層70。面向第一模11的第一成形面12合 倂配置。 參考第10圖，將裝飾面67重疊於透明樹脂層70, 來將裝飾構件60配置於成形模1 0。在將成形模1 〇進行 模具緊固之後，將芯材用的樹脂材料80射出到裝飾構件 60的背面69。而形成··將裝飾構件60、透明樹脂層70、 及芯材用的樹脂材料8 0 —體化的樹脂成形品5 0。 由於節省了將裝飾構件60與透明樹脂層70暫時接合 的步驟’所以與上述實施方式相比，能夠更減少作業程序 〇 與上述實施方式同樣地，當射出成形時能夠防止裝飾 構件60的裝飾面67產生碳化或變色，能夠提升樹脂成形 品5 0的外觀品質。則可節省在裝飾面6 7塗佈耐熱塗料等 的準備步驟’所以能提升樹脂成形品50的生產性。在變 形例’也是在裝飾構件60的第一肋部61的端面63與透 明樹脂層70的第二肋部72之間區劃形成空間5，藉由將 芯材用的樹脂材料8〇充塡到空間s內，則也能獲得：將 第一肋部61的端面63隱蔽的樹脂成形品50。 -17- 201208851 (其他變形例） 在上述實施方式，作爲裝飾構件60雖然是使用：利 用平板狀的突板的木質裝飾構件，而裝飾構件60並不限 於木質，即使是使用布、紙、金屬箔等的裝飾構件60也 可以。例如，只要是使用布的裝飾構件6 0，藉由布紋圖 樣則能構成裝飾面6 7。只要是使用紙的裝飾構件6 0的話 ，藉由紙原本表面所具備的凹凸圖樣、或紙的表面施加的 花樣、圖表、顏色區塊、色暈、文字等的圖樣，構成裝飾 面67。並且’如果是使用金燏箔等的裝飾構件60的話， 能藉由具有光澤的金屬箔的表面，構成裝飾面67。在使 用有布、紙、金屬箱等的裝飾構件60的背面，也與木質 裝飾構件同樣地能安裝用來提高剛性的背襯材。在使用布 、紙、金屬箔等作爲裝飾構件6 0的情況，樹脂成形品的 製造方法以及製造該樹脂成形品的製造裝置，與上述實施 方式相同，所以這裡省略說明。 以上’雖然針對本發明的實施方式及其變形例來說明 ’而其實施方式等，只是舉例記載用來理解本發明，本發 明並不限定於該實施方式。本發明的技術範圍，並不限於 上述實施方式等揭示的具體技術事項，也包含有由此容易 導出的各種變形、變更、代替技術等。例如，上述實施方 式的裝飾構件，雖然是將突板殘留有木紋的面利用爲裝飾 面，而裝飾面也可藉由將附有圖樣的薄膜等貼在木材等所 形成。在該情況的圖樣，並不限於木紋圖樣，可因應於使 用用途適當變更。 -18- 201208851 構成木質的裝飾構件的木材等的材質或種類、構成布 的裝飾構件的布的材質或種類、構成紙的裝飾構件的紙的 材質或種類、構成金屬箔的裝飾構件的金屬箔的材質或種 類，並沒有特別限定，可適當變更。並且，樹脂成形品的 用途，並不限於車輛用的內裝零件，可廣泛適用於家具或 構成其他圖案外觀的構件等。 本申請案，是根據2010年7月13日申請的日本特許 願第20 1 0- 1 5 9023號來主張優先權，參考該申請案的全部 內容加入本說明書。 [產業上的可利用性] 藉由本發明，藉由防止：熔融的芯材用的樹脂材料接 觸於裝飾面，可防止伴隨射出成形所產生的裝飾面的碳化 或變色。藉此，可提升樹脂成形品的外觀品質，並且節省 在裝飾面塗佈耐熱塗料等的準備步驟’能提升生產性。 【圖式簡單說明】[Technical Field] The present invention relates to a method for producing a resin molded article, a device for producing a resin molded article, and a resin molded article. [Prior Art] In order to improve the appearance of the interior parts and the like for a vehicle, a decorative member having a decorative surface formed on the surface constituting the appearance of the pattern is used. The known technique exhibits a high-grade feeling of gloss by forming a transparent resin layer on the decorative surface of the decorative member. In order to form a transparent resin layer, a method of coating a resin coating on a decorative surface may be employed. However, in the case of this method, in order to form a smooth and glossy resin layer, work such as cutting or honing is required after the application of the resin coating. Therefore, the increase in the number of operating procedures and the complication of the work result in an increase in manufacturing costs. Patent Document 1 discloses an injection molding method for forming a resin molded article in which a transparent resin layer is formed on a decorative member of wood such as a projection (refer to Patent Document η. The injection molding method is used to form a transparent resin layer toward the decorative surface. The resin material is used to achieve the efficiency of the manufacturing process.

Since the high-temperature resin material having fluidity is brought into direct contact with the decorative surface, carbonization or discoloration of the decorative surface is caused. By performing a preparation step of applying a heat-resistant paint or the like to the decorative surface in advance, it is possible to prevent carbonization or discoloration. However, in order to solve the above problems, it is an object of the present invention to provide a resin molded article manufacturing technique, which can improve the appearance quality of a resin molded article and can improve the productivity of the resin molded article. Productive. [Means for solving the problem] The present in order to achieve the above objectives One type of the resin molded article is a method in which a transparent resin layer as a surface layer is laminated on a decorative member having a decorative surface formed on the surface thereof, and the transparent resin layer is formed on a molding surface of the molding die. a step of disposing the decorative member and the transparent resin layer; and discharging a resin material for the molten core material to the back surface of the decorative member, transferring the surface shape of the molding surface to the transparent resin layer' and allowing the decoration Step of molding the resin molded article in which the member, the transparent resin layer, and the resin material for the core material are integrated. [Embodiment] Hereinafter, the present invention will be described with reference to the drawings, in the drawings -6 - 201208851 In the description, the same elements are denoted by the same reference numerals, and the overlapping description will be omitted. The dimensional ratio of the drawings may be exaggerated and may be different from the actual ratio for convenience of explanation. The embodiment of the method for producing a resin molded article will be described. According to the invention, the resin molded article is suitable for a vehicle such as a panel, a door panel, a control panel, or the like. With reference to Fig. 1 and Fig. 2, the resin molded article 50 of the embodiment is integrally formed with a decorative member 60 having a decorative surface 67 formed on its surface, and a surface layer superposed on the decorative member 60. The resin layer 70 and the resin material 80 which is a core material which is emitted to the back surface 69 of the decorative member 60. The decorative member 60 is provided with a first rib 61 formed by bending the outer peripheral portion 65 toward the back surface 69 side. The resin layer 70 includes a second rib 72 that is formed by bending the outer peripheral portion 75 toward the back surface 69 side of the decorative member 60. The first rib 61 provided in the decorative member 60 is provided with the transparent resin layer 70. The second ribs 72 are arranged to overlap each other. The end surface 63 of the first rib 61 of the decorative member 60 is covered with a resin material 80 for the core material. The decorative member 60 is bonded to the transparent resin layer 70 by a resin material 80 for a core material. Each member constituting the resin molded article will be described. Referring to Fig. 2(A), in the present embodiment, the decorative member 60 is a wooden decorative member using a flat protruding plate, and a pattern is formed by leaving the wood grain and color originally provided by the protruding plate. The decorative surface 67 is formed by the surface having the pattern. Although omitted in the drawing, a backing material for improving rigidity is attached to the back surface 69 of the decorative member 60. 201208851 Referring to Fig. 2(B), the transparent resin layer 70 is formed of a PMMA resin (polymethyl methacrylate) formed into a flat plate shape. When the mirror surface to be described later is transferred to the transparent resin layer 70, the transparent resin layer 70 imparts a gloss to the decorative surface of the decorative member 60, and exhibits a function of improving the aesthetic appearance of the visual decorative surface 67. When the rough surface to be described later is transferred to the transparent resin layer 70, the transparent resin layer 70 functions as a texture when the decorative surface 67 is visually observed or a touch when the transparent resin layer 70 is touched. The resin material of 70 is not limited to the PMMA resin, and other thermoplastic resins or the like may be used. For example, a methacrylic resin, an ABS resin, an AS resin, an ionomer resin, a polycarbonate, or the like. Even for the sake of example, it is particularly desirable to select a resin material having a light transmittance of more than 80%. This is because it is necessary to clearly see the pattern attached to the decorative surface 67. Referring to Fig. 3(A), before the injection molding, the decorative member 60 and the transparent resin layer 70 are temporarily joined to each other to form a preliminary molded body 90. The temporary bonding is performed by using a transparent adhesive 95 composed of a thermoplastic resin (see also Fig. 4(A)). The adhesive 95 interposed between the decorative surface 67 and the transparent resin layer 70 can function to increase the refractive index when the decorative surface 67 is visually observed. Thereby, the decorative surface 67 can express the unique luster or depth of the wood head provided by the protruding plate. The transparent adhesive 95 is applied to the decorative surface 67 in advance before the temporary bonding, and may be prepared to be saturated with the inside of the decorative member 60. The thickness w2 of the transparent resin layer 70 is formed to be larger than the thickness wl of the decorative member 60. The bending forming for forming the ribs 61, 201208851 72 in the preliminary formed body 90 is for preventing the occurrence of streaks in the decorative member 60. Reference is made to Fig. 4 for the purpose of preventing the crack of the decorative member 60. Referring to Fig. 4, the bending forming of the preliminary formed body 90 is carried out by using a bending forming mold 40 including a punch 41 and a die 43. When the punch 41 of the bending mold 40 is pressed close to the decorative member 60, a compressive stress mainly occurs on the inner surface side of the preliminary molded body 90 in the arrow (a) in Fig. 4(B)), and the preliminary formed body 90 is formed. The surface side mainly produces a tensile force (indicated by an arrow b in Fig. 4(B)). When both the compressive force and the tensile force largely act on the decorative member 60, the decorative member 60 is prone to cracks. Therefore, as shown in Fig. 4(A), the degree w2 of the transparent resin layer 70 is formed to be larger than the thickness w1 of the decorative member 60, so that the decorative surface 67 as the upper surface of the garnish 60 is located on the preliminary molded body 90. The neutral axis c of the thickness direction is closer to the punch 4 1 side. By this arrangement, a larger tensile force acts on the transparent resin layer 70 located on the outer surface of the preliminary formed body 90, and acts on the decorative member located on the inner surface side of the preliminary formed body 90. The tensile force of 60 is reduced. Since the decorative member ** acts as a compressive force, it is possible to appropriately prevent the occurrence of cracks. Since the crack of the decorative member 60 is appropriately prevented, the curvature of the rounded corners can be set to be large to perform bending. The thickness w of the decorative member 60 is not particularly limited, and is set, for example, to about 15 mm to about 1. mm. The thickness w2 of the transparent resin layer 70 can be set, for example, to about 5 mm to 3.0 mm. In the case of the size of the decorative member 60, the thickness w2 of the transparent resin layer 70 can be made larger than the thickness w1 of the decorative member 60 by the thickness of the transparent resin layer 70. When it is thick, it is possible to prevent cracking of the decorative member 60 at the time of bending. Referring to Fig. 1 'ABS resin is used for the resin material 80 for the core material. The resin material 80 for the core material can also be made of ABS resin. For example, 'the resin-molded core material can be suitably used: other thermoplastic resins used in general, and a plurality of thermoplastic resins, etc.. The resin material for the core material 80 uses: It is preferable to provide a material having a color similar to that of the decorative member 60 in order to prevent deterioration of the appearance of the resin material 80 for the core material to the decorative surface 67 of the decorative member 60 due to a change in time or the like. The apparatus for manufacturing a resin molded article according to the embodiment will be described. Referring to FIGS. 5 to 7 , a manufacturing apparatus 5 for a resin molded article includes a molding die 10 which is formed by a first die 11 . The second mold 21 is configured to include a first molding surface 12 in which the transparent resin layer 70 faces the same, and the second mold 21 is provided with the first mold 11 The mold is fastened to form a second molding surface 22 of the film cavity 33 on the back surface 6 9 side of the decorative member 60 (refer to Fig. 6). The second mold 21 is provided with a resin material for melting the core material. 80 is guided to the gate portion 31 of the cavity 3 3. The second die 21' of the forming die 10 is disposed to be freely movable and separated relative to the first die 11. By moving the second die 21 toward the first die 11 close to the movement 'the mold fastening of the forming die 10. The mold opening of the forming die 10 can be performed by moving the second die 21 away from the first die 11 of -10- 201208851. The transparent resin layer 70 and the transparent resin layer 70 are disposed in a temporary state of the molding die 1 (refer to Fig. 5). The decorative member 60 and the transparent resin layer 70 are placed in the mold 1 and the mold is fastened. The film cavity 33 is formed (refer to Fig. 6). After the mold is fastened, the molten resin material 80 for the core material is directed from the gate portion 31 toward the cavity 33. By using a mold, the first molding surface 12 of the first mold 11 is subjected to mirror processing to impart a mirror surface (that is, the first molding surface 12 has a mirror surface property) by using a mold. The injection temperature and the injection pressure of the resin material 80 for the material can transfer the mirror surface of the first molding surface 12 to the transparent resin layer 70. For example, the temperature of the resin material 80 for the core material is set to be smaller than the transparent resin layer 70. The glass is transferred to a higher temperature for injection, and the transparent resin layer 70 can be softened, and the transparent resin layer 70 is pressed against the first molding surface 12 of the first mold 1 1 by the injection pressure. Then, the surface shape of the mirror-finished first forming surface 12 is transferred to the pressed transparent resin layer 70. Thereby, the outer surface of the transparent resin layer 70 can be formed into a smooth and shiny surface. The surface shape of the first molding surface 12 of the first mold 11 is not particularly limited, and the first molding surface 12 may be subjected to rough surface processing so that the first molding surface 12 has a rough surface (that is, The first forming surface 12 has a rough surface property). The rough surface includes a surface shape having minute irregularities for forming a folded pattern such as leather, embossed surface polishing, wood grain, cloth, or the like. Thereby, the outer surface of the transparent resin layer 70 can be formed into, for example, a surface having a wrinkle pattern of leather, satin surface polishing, wood grain, cloth, or the like. Here, for example, when a PMMA resin having a glass transition temperature of about 110 ° C is used as the material of the transparent resin layer 70, the resin material 80 for the core material can be used, for example, an ABS resin having a melting temperature of about 26 (TC) can be used. In this case, by setting the injection pressure to about 40 MPa, the surface shape of the first molding surface 12 can be appropriately transferred to the outer surface of the transparent resin layer 70. Referring to Fig. 4, the manufacture of a resin molded article The device 5 has a bending molding die 40 for bending the decorative member 60 and the transparent resin layer 70. The bending molding die 40 is shaped to have a predetermined shape that approximates the shape of the product.
