Fig. 14 is a perspective view of a film-forming resin molded body ((10)) which is damaged on the film. The film (101) is located on the outward side of the film-inlaid resin type body (1), since the (four) resin is inlaid from the thin (4) grease-pressed body (the rear of the _ is emitted) Part of the wheel (10) is terminated by the end of the wheel (10). A portion of the film (1) of (103) (the oblique portion in the figure) is subject to damage 'as viewed from the surface, which is a trace left after being burned (104). The following is a detailed description of this situation in accordance with the fifteenth figure.

A path for forming a molten resin on the second metal mold (110) is coated with a film (1〇1) for decoration on the first metal holder (1 20), and a molten resin in a high temperature and high pressure state (such as an arrow mark). After passing through the path (111), the exit (112) which is the exit of the path (1) is directed toward the film. The result is a damage (115) on the film (101) called a gate bum. Because of the presence of the damage (115), the film inlay is observed from the surface, and the Μ月曰型型 (100) is found to have traces after burning as shown in Fig. 14 (104). The film (1) is mainly composed of an acrylic resin layer (131), a decorative layer (132), and a backing layer (133) from the side of the first metal mold (12 inch), if the decorative layer ( 132) If it is damaged, it will appear as shown in Figure 14 like the trace left after burning (1〇4). 6 200800555 ^ In order to prevent this kind of damage to the film, it is generally considered to expand the path ( The cross-sectional area of 111), the method of reducing the flow rate of the molten resin, and the method of making the ejection orifice (112) wider than the path (,), thereby reducing the flow velocity when the molten resin is emitted. The method has the following problems: In the case where the cross-sectional area of the field is enlarged (1 1 1), the hub (102) becomes thick, and as a result, when the unnecessary hub (1〇2) is removed, the method is to be cut. The broken wheel (102) becomes difficult, and a shrinkage hole is formed on the outer surface relative to the position of the hub. On the other hand, when the injection opening (112) is made wider than the path (111), although The hub formed by the overturning of the path (111) can be easily removed (1G 2), but if the ejection opening (11 2) is simply flared, the protruding portion formed by the overturning (the structure in which the projection is removed when the hub is removed) becomes thick, thereby causing shrinkage.

另外，本發明的薄膜鑲嵌型樹脂壓型體的製造方法， 尚包含將上述的射出口形狀成形為自與路徑的終端面連接 的連接面朝向射出口的開口面面積變大的形狀，所以，若 採用該薄膜鑲嵌型樹脂壓型體的製造方法的話，則熔融樹 脂在從與路徑的終端面的連接面向射出口的開口面移^ 時，能夠不捲入空氣而進行流動，使得通過射丨口的翻模 而形成的突起不捲入空氣。 另外，本發明的薄膜鑲嵌型樹脂壓型體的製造方法 尚包含將上述各射出口形成為與路徑的終端面連接的連接 面之面積大於路徑之橫截面面積的形狀，所以，若採用該 薄膜鑲嵌型樹脂壓型體的製造方法的話，則在溶融樹脂固/ 化後，因著突起和輪轂的邊界上形成明確的斷層差，而使 得在該斷層差的部位容易切斷並除去輪較。 時，能夠使熔融樹脂在金屬模具内順利流動， 如果採用本發日月，在具有加飾用薄膜的薄膜鎮嵌型樹 脂壓型體中，能夠減少注射模塑成形中對薄膜的損傷，同 減少成形後 的縮孔，並且能夠容易除去輪轂。 【實施方式】 以下，參照附圖對本發明涉及的薄膜镶嵌型樹脂壓型 體及其製造方法的適宜實施形態進行詳細說明。在各實施 9 200800555 形態中’以頂面上帶孔且呈碗形的、從頂面到侧面的表面 的一部分上鑲嵌有加飾用薄膜的薄膜鑲嵌型樹脂壓型體為 例進行說明。但是，本發明涉及的薄膜鑲嵌型樹脂壓型體， 並不限定於上述形態的薄膜鑲嵌型樹脂壓型體。 請參看第一圖’其係本發明實施形態涉及的薄膜鑲嵌 型樹脂壓型體（1)的立體圖。 薄膜鑲嵌型樹脂壓型體（V)是具有開口部（2)且呈碗形 的樹脂壓型體，其頂面上設有長方形的孔（3)，在頂面及側 面的一部分上鑲嵌有加飾用的薄膜（4)。該薄膜鑲嵌型樹脂 壓型體（1)係由聚碳酸酯（pC)/丙烯腈·丁二烯-苯乙烯樹脂 (ABS)混合塑料混合塑料構成的樹脂壓型體和薄膜（4)所構 成’其中’該薄膜（4)具有在丙烯酸類樹脂（第一薄膜（top film))和丙烯腈-丁二烯_苯乙烯樹脂樹脂（密封層）之間夾有 加飾層的三層構造。該密封層是用於在注射模塑成形時， 從熔融樹脂中保護加飾層，同時，使薄膜和注射模塑成形 樹脂溶敷的層。再者，分別將薄膜鑲嵌型樹脂壓型體（1)之 頂面稱為「表面」，將開口部（2)的内面稱為「背面」。在 薄膜鑲散型樹脂壓型體（彳）背面的孔（3)附近，並在孔（3)外 側的兩相對位置上形成有兩個突起（1〇)，該突起（1〇)是在 注射模塑成形後除去輪轂之後殘留的。 請附加參看第二圖，其係放大表示第一圖所示的突起 (10)的示意圖。 該突起（10)具有在大致呈梯形之薄板（11)的梯形面上 固定有三角形薄板（12)之端面的形狀。薄板（11)的上面（11a) 200800555 的長度W1短於薄板（11)的下面（11 b)的長度VV2。該突起（10) 是通過在注射模塑成形時從箭頭標誌L方向流過來的熔融 樹脂，並在箭頭標誌L1、箭頭標誌L2及箭頭標誌L3的 二個方向上進行分流而形成的。 再附加參看第三圖，其係表示製造第一圖所示薄膜鑲 嵌型樹脂壓型體（1)的步驟之部分示意圖。 注射模塑成形用的金屬模具（20)主要由第一金屬模具 (21)和第二金屬模具（22)構成，其中，該第一金屬模具（21) 5又有具沿著薄膜鑲嵌型樹脂壓型體（1)表面的内側的面的凹 部（23)，第二金屬模具（22)設有具沿著薄膜鑲嵌型樹脂壓 型體（1)背面的凸部（24)。在設定（setting)金屬模具（20)之 前，在第一金屬模具（21)的凹部（23)内鋪上薄膜（4);接下 來，隔著間隙（25)使第二金屬模具（22)的凸部（24)與第一金 屬模具（21)的凹部（23)相對；在第二金屬模具（22)上形成有 通過第二金屬模具（22)的内部後向凸部（24)的表面開口、 以用於朝向間隙（2 5)射出溶融樹脂的兩個溶融樹脂供給部 (30)，該熔融樹脂供給部（30)的數量實際上係兩個以上， 其僅將一部分表示於第三圖。 請參看第四圖，其係表示在熔融樹脂供給部（30)的一 部分固化的流道（40)及下澆口（41)、以及在突起（1〇)的上方 設有輪轂（15)的薄膜鑲嵌型樹脂壓型體（1)的部分示意圖。 本實施形態涉及的薄膜鑲嵌型樹脂壓型體（1 )，在相對 於輪轂（1 5)之熔融樹脂的供給上游側設有流道（40)及下澆 口（41)。該流道（40)及下澆口（41)在將第二金屬模具（22)和 11 200800555 第金屬模具（21)進行分離時被除去；該輪轂（15)及突起 (10)在第二金屬模具（22)和第一金屬模具（21)分離後，尚殘 留在薄膜鑲嵌型樹脂壓型體（1)的一側，所以若輪轂（15)過 粗的話，則成為產生縮孔，因此較佳的是形成具有大致呈 半圓形剖面的柱狀體。由於輪轂（15)對薄膜鑲嵌型樹脂壓 型體（1)來說是不需要的部分，因此成形後可藉由切斷等方 法而被除去，所得的結果是如第一圖及第二圖所示，在薄 膜鑲嵌型樹脂壓型體（1)上僅殘留有與輪轂（15)的下方連接 的突起（10)。 請參看第五圖所示，其係放大表示以第三圖中χ所標 示的虛線圍繞成圓形部分的示意圖。另外，第五圖表示從 第四圖從A所示之方向觀察金屬模具（2〇)的狀態。 該溶融樹脂供給部（3〇)係由炼融樹脂的路徑（31 )，以 及與該路徑（31)的終端面連接且向凸部（24)側開口的射出 口（32)所構成，該路徑（31)與寬度W1大於路徑寬度d的 射出口（32)連通；再者，該射出口（32)具有從與路徑（31)終 端面連接之連接面漸漸地擴大寬度、並朝向具有寬度W2 之開口面的擴散型（扇形或梯形）形狀。因此，在熔融樹脂 通過路徑（31)，並從射出口（32)射出時，其流速變小，同 時，能夠不捲入空氣而射出熔融樹脂。這樣，由於從射出 口（32)射出之熔融樹脂的流速小於通過路徑（31)時的流 速，因此能夠減少對薄膜（4)的損傷。而且，由於通過射出 口（32)形狀的翻模而形成的突起（1〇)(如第四圖所示）是氣泡 少的樹脂壓型冑，因此強度增加。其結果是在將輪轂⑽ 12 200800555 %曲進行切除時不會損壞突起（1 〇)，而能夠確實地切除輪 轂（15) 〇 明參看第六圖，其係表示從第二金屬模具（22)的凸部 (24)侧觀察射出口（32)的狀況的示意圖。 該射出口（32)係略呈τ字形狀地進行開口。其開口面 由長度W2之長方形的一面、和從長方形該面的中心在垂 直方向上僅延伸長度（W2)/2之長方形的面所構成。因此， 熔融樹脂被射出時係沿著射出口（32)的開口形狀從路徑（31) 向二個方向擴散。其結果是能夠使熔融樹脂接觸於薄膜（4) 時的流速變小，同時，能夠使在三個方向上流過間隙（25) 内之溶融樹脂的流速在某種程度上增大，從而使熔融樹脂 不會對薄膜（4)帶來大的損傷，並且能夠順利地流過金屬模 具（20)内的間隙（25)，故從表面觀察薄膜，則不會存在 有如被燃燒般的情況，並且樹脂能夠被填充到間隙（25)的 各個角落。另外，如果使射出口（32)的寬度（相當於薄板（11) 及二角形薄板（12)的厚度的部分）相對於間隙（25)的高度H 在1/2或1/2以上、且2/3或2/3以下的範圍内的話，則 不會形成大的壁厚部，所以能夠抑制縮孔的發生。 請參看第三、五及七至九圖所示，第七圖係表示薄膜 鑲嵌型樹脂壓型體（1)的主要製造步驟的流程圖。第八圖是 表不除去輪轂（15)之前的薄膜鑲嵌型樹脂壓型體（彳）的示意 圖。第九圖是放大表示第八圖所示的輪轂（15)和突起（1〇) 的部分的示意圖。 首先’在第一金屬模具（21)的内侧配置加飾用的薄膜 13 200800555 (4)(步驟S1 01 :薄膜的配置步驟）；接著，使第二金屬模 具（22)的凸部（24)與第一金屬模具（21)的凹部（23)的上方相 對’而設定金屬模具（20)(步驟S102 ··金屬模具的設定步 驟）；接下來，從射出口（32)向第一金屬模具（21)和第二金 屬模具（22)之間的間隙（25)射出由240。(：〜26〇°c的 PC/ABS混合塑料構成的熔融樹脂（步驟s1〇3··樹脂的射 出步驟），在樹脂射出步驟S1 03期間，金屬模具（20)被保 持在40 C〜60°C ;接下來，在熔融樹脂固化後，將第一金 _ 屬模具（21)和第二金屬模具（22)進行分離（步驟S1 04 :金 屬模具的分離步驟）；在進行了步驟s彳〇4之後的薄膜鑲嵌 型树脂壓型體（1)具有第八圖所示之形態的樹脂壓型體，成 為形成有輪轂（15)的狀態；接下來，將從突起（1〇)延伸的 輪轂（15)自突起（1〇)除去（步驟si05)。如第九圖所示，由 於突起（10)上方的輪轂（15)的終端面的面積S1 (第九圖中的 以斜線表示的領域）小於突起（1〇)的上面（11a)的面積s2， 因此能夠在突起（10)的上面（11a)容易地切除輪轂（15);最 後即可獲得薄膜鑲嵌型樹脂壓型體（彳）。 ”月參看第十、十-、十二及十三圖所示，其係表示突 起（1〇)和輪轂（15)組合之變形例的示意圖。另外，在這些 圖中，考慮到輪轂（15)為最後被除去的部分，因此以點劃 線表示輪轂（1 5)。 如第五及十圖所示，突起（10)也可以具有冑兩塊大致 呈梯形的薄板（11)進行交叉（cross)的形態。若將第二金屬 模具（22)之射出口（32)的形狀設計為能夠形成這種形態的 200800555 突起（10)，則溶融樹脂從射出口（32)流向四個方向。根據 薄膜鑲嵌型樹脂壓型體（1)的形態和射出口（32)的位置，也 可採用能形成對應第十圖所示之突起（10)的射出口（32)。 再者，如第五及十一圖所示，本發明也可以將突起（10) 成形為在一長方體薄板（13)最寬的一個側面上固定一長方 體薄板（14)之端面的形 金屬模具（22)的射出 右Moreover, the method for producing a film-inserted resin molded body according to the present invention further includes a shape in which the shape of the above-described ejection opening is formed such that a surface of the connection surface connected to the end surface of the path increases toward the opening surface of the ejection opening. When the method for producing a film-inlaid resin molded body is used, when the molten resin is moved from the connection surface to the end surface of the path toward the opening surface of the ejection opening, it is possible to flow without being entrained with air, so that the molten resin can be flown through The protrusion formed by the overturning of the mouth is not caught in the air. Further, the method for producing a film-inserted resin molded body according to the present invention further comprises forming the respective ejection openings such that the area of the connection surface connected to the end surface of the path is larger than the cross-sectional area of the path, and therefore, the film is used. In the method for producing the inlaid resin molded body, after the molten resin is solidified, a clear gap difference is formed on the boundary between the projection and the hub, so that the portion where the fault is poor is easily cut and the wheel is removed. In this case, the molten resin can be smoothly flowed in the mold, and in the case of the film-inlay type resin molded body having the film for decoration, the damage to the film during injection molding can be reduced. The shrinkage cavities after forming are reduced, and the hub can be easily removed. [Embodiment] Hereinafter, a preferred embodiment of a film-inserted resin molded body and a method for producing the same according to the present invention will be described in detail with reference to the accompanying drawings. In the embodiment of the present invention, a film-inlaid resin molded body in which a decorative film is embedded in a part of a surface of a top surface to a side surface which is perforated and has a bowl shape on the top surface will be described as an example. However, the film-inserted resin molded body according to the present invention is not limited to the film-inserted resin molded body of the above aspect. Referring to the first drawing, a perspective view of a film-inserted resin molded body (1) according to an embodiment of the present invention is shown. The film-inlaid resin molded body (V) is a resin molded body having an opening portion (2) and having a bowl shape, and has a rectangular hole (3) on its top surface, and is embedded in a part of the top surface and the side surface. Film for decoration (4). The film-inserted resin molded body (1) is composed of a resin molded body and a film (4) composed of a polycarbonate (pC)/acrylonitrile butadiene-styrene resin (ABS) mixed plastic mixed plastic. The film (4) has a three-layer structure in which a decorative layer is interposed between an acrylic resin (a top film) and an acrylonitrile-butadiene-styrene resin (sealing layer). The sealing layer is a layer for protecting the decorative layer from the molten resin at the time of injection molding, and simultaneously coating the film and the injection-molded resin. Further, the top surface of the film-inlaid resin molded body (1) is referred to as "surface", and the inner surface of the opening (2) is referred to as "back surface". Two protrusions (1〇) are formed in the vicinity of the hole (3) on the back surface of the film-inserted resin molded body (彳), and at two opposite positions on the outside of the hole (3), the protrusion (1〇) is Remaining after removal of the hub after injection molding. Referring additionally to the second drawing, it is a schematic view showing the protrusion (10) shown in the first figure in an enlarged manner. The projection (10) has a shape in which an end surface of a triangular thin plate (12) is fixed on a trapezoidal surface of a substantially trapezoidal thin plate (11). The length W1 of the upper surface (11a) of the thin plate (11) 200800555 is shorter than the length VV2 of the lower surface (11b) of the thin plate (11). The projection (10) is formed by shuffling the molten resin from the direction of the arrow mark L during injection molding, and is divided in two directions of the arrow mark L1, the arrow mark L2, and the arrow mark L3. Referring additionally to Fig. 3, there is shown a partial schematic view showing the steps of manufacturing the film-inserted resin molded body (1) shown in Fig. 1. The metal mold (20) for injection molding is mainly composed of a first metal mold (21) and a second metal mold (22), wherein the first metal mold (21) 5 has a resin embedded along the film. The concave portion (23) on the inner surface of the surface of the molded body (1), and the second metal mold (22) is provided with a convex portion (24) having a back surface along the film-inserted resin molded body (1). Before the setting of the metal mold (20), the film (4) is laid in the recess (23) of the first metal mold (21); next, the second metal mold (22) is interposed via the gap (25). The convex portion (24) is opposite to the concave portion (23) of the first metal mold (21); and the second metal mold (22) is formed with the inner rearward convex portion (24) passing through the second metal mold (22) The surface of the molten resin supply portion (30) for opening the molten resin toward the gap (25), the number of the molten resin supply portion (30) is actually two or more, and only a part thereof is expressed in the first Three pictures. Referring to the fourth drawing, the flow path (40) and the lower gate (41) which are partially solidified in the molten resin supply portion (30), and the hub (15) are provided above the protrusion (1). A partial schematic view of a film inlaid resin molded body (1). The film-inserted resin molded body (1) according to the present embodiment is provided with a flow path (40) and a lower gate (41) on the upstream side of the supply of the molten resin to the hub (15). The flow path (40) and the lower gate (41) are removed when the second metal mold (22) and the 11 200800555 metal mold (21) are separated; the hub (15) and the protrusion (10) are in the second Since the metal mold (22) and the first metal mold (21) are separated from each other on the side of the thin film-inserted resin molded body (1), if the hub (15) is too thick, shrinkage holes are formed. It is preferred to form a columnar body having a substantially semi-circular cross section. Since the hub (15) is an unnecessary portion for the film-inlaid resin molded body (1), it can be removed by cutting or the like after molding, and the result is as shown in the first figure and the second figure. As shown in the figure, only the projections (10) connected to the lower side of the hub (15) remain on the film-inserted resin molded body (1). Referring to the fifth figure, it is an enlarged view showing a circular portion surrounded by a broken line indicated by χ in the third figure. Further, the fifth diagram shows a state in which the metal mold (2 turns) is viewed from the direction indicated by A in the fourth figure. The molten resin supply unit (3) is composed of a path (31) for melting the resin, and an injection port (32) connected to the end surface of the path (31) and opening to the side of the convex portion (24). The path (31) is in communication with the ejection opening (32) having a width W1 larger than the path width d; further, the ejection opening (32) has a width gradually increasing from the connecting surface connected to the end surface of the path (31), and has a width toward the width A diffused (sector or trapezoidal) shape of the open face of W2. Therefore, when the molten resin passes through the path (31) and is emitted from the ejection opening (32), the flow velocity thereof becomes small, and at the same time, the molten resin can be ejected without entraining air. Thus, since the flow velocity of the molten resin ejected from the ejection opening (32) is smaller than the flow velocity when passing through the path (31), damage to the film (4) can be reduced. Further, since the projection (1〇) formed by the overturning of the shape of the ejection opening (32) (as shown in the fourth drawing) is a resin molded crucible having a small number of bubbles, the strength is increased. As a result, the protrusion (1 〇) is not damaged when the hub (10) 12 200800555 % is cut, and the hub (15) can be surely cut out. Referring to the sixth figure, it is shown from the second metal mold (22). A schematic view of the condition of the ejection opening (32) on the side of the convex portion (24). The ejection opening (32) is opened in a slightly zigzag shape. The opening surface is formed by a rectangular one surface having a length W2 and a rectangular surface extending from the center of the rectangular surface by a length (W2)/2 in the vertical direction. Therefore, when the molten resin is emitted, it is diffused from the path (31) in two directions along the opening shape of the ejection opening (32). As a result, the flow velocity at which the molten resin is brought into contact with the film (4) becomes small, and at the same time, the flow velocity of the molten resin flowing in the gap (25) in three directions can be increased to some extent, thereby melting. The resin does not cause great damage to the film (4), and can smoothly flow through the gap (25) in the metal mold (20), so that the film is not observed to be burned as it is observed from the surface, and The resin can be filled into various corners of the gap (25). Further, if the width of the ejection opening (32) (the portion corresponding to the thickness of the thin plate (11) and the rectangular thin plate (12)) is 1/2 or more or more with respect to the height H of the gap (25), and In the range of 2/3 or 2/3 or less, a large thickness portion is not formed, so that occurrence of shrinkage cavities can be suppressed. Referring to Figures 3, 5 and 7 to 9, the seventh drawing shows a flow chart showing the main manufacturing steps of the film-inlaid resin molded body (1). The eighth figure is a schematic view showing a film-inserted resin molded body (彳) before the removal of the hub (15). The ninth drawing is a schematic view showing a portion of the hub (15) and the projection (1) shown in the eighth diagram in an enlarged manner. First, a decorative film 13 200800555 (4) is disposed inside the first metal mold (21) (step S1 01: film arrangement step); then, the convex portion (24) of the second metal mold (22) is made The metal mold (20) is set opposite to the upper side of the concave portion (23) of the first metal mold (21) (step S102: setting step of the metal mold); next, from the ejection opening (32) to the first metal mold A gap (25) between (21) and the second metal mold (22) is emitted by 240. (: a molten resin composed of PC/ABS mixed plastic of ～26°°c (step s1〇3·· resin ejection step), during the resin injection step S1 03, the metal mold (20) is held at 40 C to 60 °C; next, after the molten resin is solidified, the first gold mold (21) and the second metal mold (22) are separated (step S1 04: separation step of the metal mold); after the step s彳The film-inlaid resin molded body (1) after the crucible 4 has a resin molded body of the form shown in FIG. 8 and is in a state in which the hub (15) is formed. Next, it is extended from the protrusion (1). The hub (15) is removed from the protrusion (step 05). As shown in the ninth figure, the area S1 of the end face of the hub (15) above the protrusion (10) (indicated by the slanted line in the ninth figure) The area is smaller than the area s2 of the upper surface (11a) of the protrusion (11a), so that the hub (15) can be easily cut off on the upper surface (11a) of the protrusion (10); finally, the film-inserted resin molded body can be obtained (彳". See the tenth, tenth, twelfth and thirteenth figures for the month, which means the protrusions (1〇) and the wheel A schematic view of a modification of the combination of the hubs (15). In addition, in these figures, considering that the hub (15) is the last removed portion, the hub (15) is indicated by a chain line. It is to be noted that the protrusion (10) may have a shape in which two substantially trapezoidal thin plates (11) are crossed. The shape of the exit (32) of the second metal mold (22) is designed to be able to form In the form of the 200800555 protrusion (10), the molten resin flows from the ejection port (32) in four directions. According to the shape of the film-inserted resin molded body (1) and the position of the ejection opening (32), it is also possible to form Corresponding to the ejection opening (32) of the protrusion (10) shown in Fig. 10. Further, as shown in the fifth and eleventh drawings, the present invention can also form the protrusion (10) into a rectangular parallelepiped (13). a metal mold (22) that is fixed to the end surface of a rectangular parallelepiped (14) on one side of the width

Further, since the areas above and below the protrusions are the same, the molten resin from the path (31) reduces the flow velocity when entering the ejection opening (32), and flows out from the ejection opening (32) at a substantially constant speed. Further, it is also possible to adopt a projection in which two long pieces of the body; the thin plates (13) (14) of the body are crossed. Further, as in the second and twelfth drawings, the shape of the projection (10) of the present invention can be formed into the same shape as that of the projection (10) shown in the second figure, so that the area of the end surface of the hub (15) is made. S1 (the area indicated by the oblique line in the twelfth figure) is the same as the area S2 of the upper surface (11a) of the protrusion (1〇).

As a specific evaluation standard of the gate burnt, the case where there is almost no damage is evaluated as "〇" The case where the damage is small is evaluated as Δ', and the case where the damage is large is evaluated as "X". In addition, the degree of filling of the resin in the shot 4 volume is evaluated as 17 200800555 "Insufficient" if it is not sufficiently filled. (Comparative Example 1) In the first metal mold, the path having the half-moon shape cross section is stretched as it is, and then it is extended as an exit pupil. The opening area of the one-shot is set to 4.6 mm 2 (mm 2 ), and In the second metal mold A total of three ejection ridges are provided. The same conditions as in the above embodiment are employed for the ejection volume, the resin to be ejected, the temperature at which the resin is ejected, the temperature of the molten resin, the temperature of the metal mold during injection molding, and the film.

如表1所示，在比較例1〜6的條件下產生了澆口燒 痕。通過射出口的流速，通過將射出時間調整長而變小， 但是不至於消除洗口燒痕。另外，在比較例3、比較例4 及比較例6的情況下，由於射出時間過於長，溶融樹脂產 生固化從而使流動性降低，使得射出容積内填充不足而獲 得評價“不足”。 相對於此，在實施例的條件的情況下，由於通過射出 口的流速充分變小，因此未發生澆口燒痕的狀況。另外， 溶融樹脂充分填充於射出容積中。 20 200800555 I上述結果，採用了能夠形成對切斷除去沒有障礙的 • 粗度的輪轂’即使讓射出時間發生變化，澆口燒痕也會產 生。如果使射出時間變長的話，通過射出口的流速變小， 使看到澆口燒痕的程度有變小的傾向，但另一方面卻產生 J熔融樹脂填充不足的問題。由此可以認為在射出時間的 周正中$此多句使防止洗口燒痕產生和充分填充炼融樹脂 二者兩全（並存）。 #對於此，如果將從路徑連續的射出Π形成如實施例 m 之路徑形狀，則能夠使通過射出口的流速充分變小，同時， 能夠在分流之後使熔融樹脂的流速變小。其結果可認為是 能夠使防止》口燒痕產生和A分填充炼融樹脂二者兩全。 產業利用性 本發明可以利用於採用通過注射模塑成形镶嵌了加飾 薄膜的樹脂壓型體的電子設備、汽車的内裝零件等的製造 或使用產業上。 【圖式簡單說明】 第-圖K本發明的實施丨態涉及的薄膜镶嵌型樹脂壓 型體的立體圖。 第二圖是放大表示第一圖所示的突起的示意圖。 第三圖是表示製造第-圖所示薄膜镶嵌型樹脂壓型體 的步驟的一部分的示意圖。 第四圖I表示在炼融樹脂供給部的一部分上固化的流 道（runner)及下澆口（submarine gate)、和在突起的上方設 21 200800555 有輪轂的薄膜鑲散型樹脂壓型體的一部分的示意圖。 第五圖是放大表示以第三圖的X所示的虛線圍繞成圓 形的部分的不意圖。 第六圖疋表示從第二金屬模具的凸部側觀察射出口的 形狀的示意圖。 第七圖是表示薄膜鑲嵌型樹脂壓型體的主要製造步驟 的流程圖。 第八圖是表示除去輪轂前的薄膜鑲嵌型樹脂壓型體的 _ 示意圖。 第九圖疋放大表示第八圖所示的輪轂和突起的部分的 示意圖。 第十圖疋表示第九圖所示突起和輪轂的組合以外的變 形例的示意圖。 第十一圖是表示第九圖所示突起和輪轂的組合以外的 變形例的示意圖。 _ 第十二圖是表示第九圖所示突起和輪轂的組合以外的 變形例的示意圖。 第十三圖是表示第九圖所示突起和輪轂的組合以外的 變形例的示意圖。 第十四圖是薄膜上產生損傷的薄膜鑲嵌型樹脂壓型體 的立體圖。 第十五圖是用於說明注射模塑成形時薄膜上產生損傷 的狀況的示意圖。 【主要元件符號說明】 22 200800555 (1)薄膜鑲嵌型樹脂壓型體 （2)開口部 (3)孔 （4)薄膜As shown in Table 1, gate burns were produced under the conditions of Comparative Examples 1 to 6. The flow rate through the ejection orifice is made smaller by adjusting the injection time, but the burnout is not eliminated. Further, in the case of Comparative Example 3, Comparative Example 4, and Comparative Example 6, since the injection time was too long, the molten resin was solidified to lower the fluidity, and the filling in the ejection volume was insufficient to obtain an evaluation "insufficient". On the other hand, in the case of the conditions of the examples, since the flow velocity through the ejection openings was sufficiently small, no gate burnout occurred. Further, the molten resin is sufficiently filled in the ejection volume. 20 200800555 I As a result of the above, it is possible to form a hub which can form a thickness which is cut without removing the obstacle. Even if the injection time is changed, the gate burn marks are generated. When the injection time is made longer, the flow velocity through the ejection orifice becomes smaller, and the degree of burnt of the gate tends to be small, but on the other hand, there is a problem that the J-melting resin is insufficiently filled. From this, it can be considered that the multi-sentence in the circumference of the injection time prevents both the generation of the burn-in burn marks and the full filling of the smelting resin (coexistence). # In this case, if the path shape of the embodiment m is formed from the continuous exit pupil of the path, the flow velocity through the ejection orifice can be sufficiently reduced, and the flow velocity of the molten resin can be made small after the splitting. As a result, it can be considered that both the prevention of the occurrence of the burnout of the mouth and the filling of the resin of the A portion can be achieved. Industrial Applicability The present invention can be utilized in the manufacture or use of electronic equipment, automobile interior parts, and the like which are formed by injection molding of a resin molded body in which a decorative film is embedded.
