Description of the Invention: [Technical Field] The present invention relates to a three-dimensional transfer method, in which a method of driving injection molding and transferring in a mold is carried out in [Prior Art] • In addition to the color of its own, if the word or pattern is formed on the surface, it is usually printed. = ink is printed on the surface of the finished product. However, since the surface of the finished product is flat, it will be quite difficult to print. On the other hand, because the soil is stuck on the finished product, and the plastic surface is smooth, the adhesion of the ink is not Good, often easy to fade due to friction, so the way of printing and coloring is not ideal. In order to improve the aforementioned drawbacks, a coloring method for simultaneous printing transfer in an injection molding tool was developed, which is called in-mold decoration injection (m_m〇ld dec〇ration, IMD). The general steps of in-mold decoration injection include: · 1) film multi-color printing (printed film), first printing the desired printed text pattern on a substrate film; 2 · three-dimensional modeling of high pressure f0rming, HPF The high-pressure air is used to press the aforementioned substrate film into a three-dimensional shape of the mold; 3) Die cut 〇 〇 〇 , , , D D D D D D D D D D D D D D D D D D D D D D D D D D D D D D D D D After injection molding, the three-dimensional modeling substrate film is placed in a mold and then subjected to injection processing. In this way, the base film will be attached to the surface of the finished product together with the ink, so it is also 5 1279307 private, and the core is labeled. Another relatively similar process, after the ink is attached, the substrate film can be detached from the finished product, which is called in-mold transfer. ' • However, the current processing method for in-mold decoration injection has a very high defect rate. The reason is that the ink printed on the substrate film is subjected to secondary processing (including • high pressure molding, stamping cutting and injection processing), and its quality becomes less stable. The melting point of the ink is 135 ° C, and the general shot The processing of the plastic raw materials into the Φ: the degree of the dish is between 160~280 °c, so when the ink hits the high temperature of the plastic raw materials to keep the ink, the phenomenon of ink displacement occurs in the valley solution, so that the printed text or looks _ no clear. In addition, since the physical properties of the ink become brittle after printing and drying, the high-pressure molding and the punching and cutting are strongly bent by the base film, and the ink at the bending often breaks, resulting in light transmission there. . Even if the aforementioned disadvantages are all improved, the adhesion of the ink to the plastic surface after the transfer to the plastic surface is still limited, and the ink is still easy to fall off after use. On the other hand, in the process of transfer, the substrate film printed with characters or patterns must be subjected to high-pressure molding and stamping, and then the substrate film is placed in a mold for injection processing, in the manufacturing process. It is inconvenient to add the steps, and it is necessary to additionally provide a mold for high-pressure molding and punch cutting, which further increases the production cost. The plastic mold interior decoration has been known for many years, and the automatic injection processing of silicone rubber is another important development field in recent years, especially its special texture, which is in many business. ΠApplications have achieved quite good results. However, all the finished products of the silicone injection molding, if they want to add a pattern or a text to the finished product, are transferred or printed on the finished product after molding on 6 1279307. The result is as described above, and the printed surface is not flat. In the case of printing, it is quite difficult to print. On the other hand, because the ink is stuck on the finished product, the adhesion is not good, and it is often easy to fade due to friction, and the adhesive is poor, and the finished product is transferred. The saturation of the color is insufficient, and the outline of the pattern or the text is also unclear. SUMMARY OF THE INVENTION In order to improve the adhesion of the ink to the formed silicone, and at the same time improve the steps of the conversion, and reduce the equipment cost required for the process, the present invention provides a method for using the in-mold decoration. Dream gel injection molding _ use, there are: glue ink, the ink transfer printing in the mold three-dimensional transfer side: The ink containing the hair gel is combined with the body of the Shijiao gel during injection molding, which greatly increases the adhesion of the ink to the body of the 11 glue, so that the ink has no 虞 且 and at the same time has better color saturation and clearer The gallery. In terms of the design of the mold and the transfer mechanism, the injection molding process is simplified, and the step of transfer in the handle increases the efficiency of production, and the equipment cost required for low production in the same domain. Shi Xiwei The method for turning over the miscellaneous printing of the present invention comprises: (1) providing an ink mixed with (2) using the ink containing the silicone rubber on the substrate film; (7) using the base film The upper text pattern is positioned to take 杈 (4) Guan Quan 'clamping; (5) sputum injection; and (6) mold opening, out of Shishi plastic finished product. Wherein, the substrate film is wound by two roller layers, and the transfer of the next pattern character can be continued after a pattern text is transferred. ^ By this month, after a mold is closed and clamped, the transfer substrate is clamped 7 1279307; the molding space formed between the two pullers is connected for injection processing. Injection processing 砗, 叮 / Zheng 丨 ji # (four) plus Wang Ricai 'can use solid or liquid stone 夕 尉 尉 猎 猎 猎 猎 猎 猎 猎 猎 猎 猎 猎 猎 猎 猎 猎 猎 猎 猎 猎 猎 猎 猎 猎 猎 猎 猎 猎Then, by heating the stone-like collagen in the mold with the heating device connected to the =-changer and the second mold, the injected raw material is heated and then ejected in the injection mechanism, and is moved into the mold. In the process, the ink can be fused with the injection material during the heating process to increase the adhesion of the ink, so that the ink is less likely to fall off. Since the Shiyue transfer device of the present invention eliminates the steps of high pressure molding, stamping and cutting, and the equipment, the cost of the injection molding and transfer process is saved, and the production capacity can be greatly increased.
