Therefore, the in-mold injection molding method of the surface of the finished product of the present invention is a method of gluing a textile with a plate, and forming a combination of the textile and the plate to form a predetermined shape, and then placing the combined body. The inside of the forming is formed by in-mold injection molding. The resulting finished product comprises a plastic body and a textile glued to the surface of the plastic body. By using the color or pattern of the textile itself, it can replace the traditional pattern or color on the outer surface of the injection molded product by coating the ink pigment or printing, thereby not only reducing the use of the ink pigment, but also improving the appearance of the product. Texture and yield. The above and other technical contents, features and effects of the present invention will be apparent from the following detailed description of the preferred embodiments. The in-mold injection molding method for the surface of the finished product of the present invention and the finished product thereof are mainly for attaching and affixing the textile to the outer surface of the finished product by injection molding, so that the outer surface of the finished product is The textile fabric can be used as a mobile phone, pDA $ notebook computer and other electronic devices: the shell '- can increase the quality of the electronic device shell, and the second can also replace the old direct coating pigment or The way in which the printing method forms a pattern or color on the outer casing reduces the waste of the pigment and avoids contamination of the environment by the pigment. Referring to Fig. 1, a preferred embodiment of the invention is a molded article comprising a veneer and a fabric u, a matte 12, an ancient f*, a forming 13, a cutting 14 and In-mold injection molding 15 and the like.鬲1 Referring to Figure 2, wherein the step 1" of the knee panel and the textile is coated with an adhesive layer 23 between the sheet 22 and the textile 21,
與紡織物21可相黏貼膠合而構成一結合體2。 T 主於材質:面，本實施例之板材22所使用的材質為丙溪 日月-丁一烯-苯乙烯（Acry1〇nitrile_butadie_ 吻r 如 e 、 ，ABS)，但並不以此為限，該板材22之材質亦可 聚對苯二甲酸乙醇酉旨（polyethylene terephth_e，奸丁）、 聚碳酸酯（Poly Carb〇nate，PC)等，或採用與即將進行射 出成形的塑料相同之材質，或者是採用如銅、鋁、鐵、白 鐵等至屬；I：才貝。紡織才勿21彳為經緯交織物、編織帶、針織 物、鉤針織物或刺繡織物，具體來說，如麻、紗、網、1 、棉布、毛線布料、尼龍布料、具有刺繡圖樣之布料等均 可被應用於此。而黏膠層23之材質則是採用混合液加架橋 劑，但同樣不以此為限，亦可使用如硬化劑、熱溶膠、熱 熔膠膜等或上述之組合。 、，閱圖1、圖3，熱壓的步驟12是在板材22與紡織物 21塗佈黏膠層23以相膠合成結合體2之後，再以加熱之滾 輪3對結合體2進行熱滾壓，其目的在於熱融黏膠層23而 使、、方、、哉物21與板材22之黏貼膠合達到鏈結固化，加強板 材22與、、方織物21貼合之牢固性，防止紡織物2工輕易脫落 參閱圖1、圖4 圖5，接著，於高壓成形的步驟13中 1301791 ，是以-高壓成形設備4對該結合體2進行塑形作業而形 成一預定形狀，例如，若該高壓成形設備4採用沖床，該 步驟13則是對該結合體2進行沖壓作f，使該結合體2產 生形變。其目的在於如® 8及圖9所示，使該結合體2被 放入模具5内時，結合體2之外型可與模具5内壁相貼合 ，也就是當射出成型之塑料6凝固為成品日寺，纺織物Μ ^ 可完全依照成品的外表面起伏而貼合於成品的外表面，而 該高壓成形㈣13亦可以如真空成形或熱壓成形之方式進 行。 參閱圖1、圖6、圖7,而於裁切的步驟14中，是對塑 形後的結合體2進行多餘部分之裁切，使該結合體2的外 型輪廓被裁切成-預定之形狀，以配合即將覆蓋之射出成 型成品的外表面輪廓形狀（如圖9所示），該裁切步驟Η 可以沖床4進行沖壓下料或雷射切割之加卫方式為之，但 加工方式不在此限，諸如線㈣或其㈣以裁切板材、布 料之方式亦可，當然，若紡織物21與板材22於黏合前便 已裁切成預定之形狀，此裁切步驟14亦可省略。 參閱圖1、圖8、圖9’完成結合體2之外型裁切之後 ’便可將結合豸2放置入射出成型的模具5内，以進行模 内射出成型之步驟15’且結合體2在置入模具5時，是以 纺織物21的-侧靠抵於模具5的内壁面，而板材22則是 面向模具5的腔室5卜以便塑料6注人模具5内進行射出 成里日守塑料6與板材22相結合。而待塑料6冷卻凝固後 ’便可取出成品。The woven fabric 21 can be adhered and glued to form a combined body 2. T is mainly used for material: surface. The material used for the sheet 22 of the present embodiment is acrylonitrile-butyrene-styrene (Acry1〇nitrile_butadie_ kiss r such as e, ABS), but not limited thereto. The material of the plate 22 may also be polyethylene terephthine (polyethylene terephth_e), polycarbonate (Poly Carb〇nate, PC), or the like, or the same material as the plastic to be injection molded, or Is the use of such as copper, aluminum, iron, white iron, etc.; I: only shellfish. Textiles are not used for warp and weft fabrics, woven belts, knitted fabrics, crocheted fabrics or embroidered fabrics, specifically, such as hemp, yarn, net, 1, cotton, wool fabric, nylon fabric, fabric with embroidery pattern, etc. Can be applied to this. The material of the adhesive layer 23 is a mixture of a bridge and a bridge, but it is not limited thereto. For example, a hardener, a hot melt, a hot melt adhesive film or the like or a combination thereof may be used. Referring to FIG. 1 and FIG. 3, the step 12 of hot pressing is to apply the adhesive layer 23 to the textile material 21 to form the bonded body 2, and then heat-roll the combined body 2 with the heated roller 3. The purpose of pressing, the purpose is to thermally melt the adhesive layer 23 to make the adhesive bond of the square, the material 21 and the sheet 22 to the chain to solidify, and to strengthen the adhesion of the sheet 22 and the square fabric 21 to prevent the textile. 2, easy to fall off, refer to FIG. 1, FIG. 4, FIG. 5, and then, in step 13 of the high-pressure forming, 1301791, the combined body 2 is shaped by the high-pressure forming apparatus 4 to form a predetermined shape, for example, if The high pressure forming apparatus 4 employs a punching machine, and in this step 13, the combined body 2 is punched to f, and the combined body 2 is deformed. The purpose is as shown in Fig. 8 and Fig. 9, when the combined body 2 is placed in the mold 5, the outer shape of the combined body 2 can be adhered to the inner wall of the mold 5, that is, when the injection molded plastic 6 is solidified into The finished Japanese temple, the textile material Μ ^ can be attached to the outer surface of the finished product according to the outer surface of the finished product, and the high-pressure forming (four) 13 can also be carried out by vacuum forming or hot press forming. Referring to FIG. 1, FIG. 6, and FIG. 7, in the step 14 of cutting, the excess portion of the combined body 2 is cut, so that the contour of the combined body 2 is cut into a predetermined The shape is matched with the contour shape of the outer surface of the injection molded product to be covered (as shown in FIG. 9), and the cutting step Η can be punched or punched by the punching machine 4, but the processing method is Except for this limitation, such as the line (4) or (4), the sheet or the cloth may be cut. Of course, if the textile 21 and the sheet 22 have been cut into a predetermined shape before being bonded, the cutting step 14 may be omitted. . Referring to FIG. 1, FIG. 8 and FIG. 9', after the outer body 2 is cut, the bonding 豸 2 can be placed in the mold 5 which is injected into the molding to perform the in-mold injection molding step 15' and the combined body 2 When the mold 5 is placed, the side of the textile 21 is placed against the inner wall surface of the mold 5, and the sheet 22 is the chamber 5 facing the mold 5 so that the plastic 6 is injected into the mold 5 to be ejected. The plastic 6 is combined with the sheet 22. After the plastic 6 is cooled and solidified, the finished product can be taken out.
