Description

Structure of objects with composite thin films and their manufacturing methods

This invention relates to a transparent, semi-transparent, or non-transparent article structure and a method for manufacturing the same; particularly, it relates to a film-combined article structure and a method for manufacturing the same; and even more particularly, it relates to a film-combined article structure and method suitable for manufacturing various shaped structures, housing structures, or optical lens devices.

Regarding conventional injection molding apparatuses and objects, for example, U.S. Patent No. US-5098281, "Injection mold capable of shearing film gate within mold," discloses an injection molding apparatus. This apparatus has an injection molding mold, and the injection molding mold mainly comprises a mold cavity, a film gate of resin, and a gate cutter.

Continuing on, the mold cavity of the aforementioned patent US-5098281 includes a die having a bore with an axis and a diameter. The resin film gate is formed within the injection mold, and the gate is sheared by the individual movement of the gate cutter.

Continuing on, the gate cutter of the aforementioned patent US-5098281 has a stepped cylindrical form, which includes a main cylindrical portion and a coaxial end cylindrical portion, wherein the main cylindrical portion has a larger diameter and the coaxial end cylindrical portion has a smaller diameter.

Continuing on, when the injection molding die of the aforementioned patent US-5098281 is closed, the cylindrical portion of the common end is inserted into the bore of the confronting die, and an annular gap is formed between the cylindrical portion of the common end and the bore of the confronting die. This annular gap has a radial size, and this radial size forms a gate thickness.

Continuing from the above, patent number US-5098281 defines a gate land by forming the outer peripheral surface of a portion of the gate cutter (the cylindrical portion at the common end) inserted into the bore of the aligned mold.

However, the injection molding die described in the aforementioned patent US-5098281 only employs the structure of the mold cavity, resin film gate, and gate knife, and how to operate the injection molding operation; it is not applicable for selectively combining the film and the injection-molded product (e.g., manufacturing plastic products or products with similar properties).

Another common method and object for preparing blown films of copolymers is, for example, U.S. Patent No. 5658526, "Method to prepare blown films of vinyl aromatic/conjugated diolefin block copolymer," which discloses a method for preparing blown films of vinyl aromatic/conjugated diolefin block copolymers. This method uses a circular die.

Continuing on, the method for blowing a film from the copolymer described in the aforementioned patent US-5658526 comprises: first, providing an elastomeric composition, wherein the block copolymer composition comprises at least one block copolymer of vinyl aromatic and at least one conjugated block copolymer.

Continuing on, the method for blowing a film from the copolymer according to the aforementioned patent US-5658526 includes: subsequently melting the block copolymer composition in an extruder or extruder to obtain a melted block copolymer composition.

Continuing on, the method for blowing a copolymer film according to the aforementioned patent US-5658526 includes: then passing the molten block copolymer composition from the extruder through a circular die, the circular die including a circular outlet and a tapered channel, the tapered channel leading to the circular outlet, the circular outlet having an opening width of approximately 2.28 × ^10⁻² inches, the tapered channel having a linearly tapered shape of approximately 1 inch in length, the linearly tapered shape forming an angle from a center away from a center of the circular outlet, the angle of a line perpendicular to the circular outlet being approximately 10°, and the die having a source of gas pressure located within the circular outlet.

Continuing on, the method for blowing a film from the copolymer described in the aforementioned patent US-5658526 includes: subsequently cooling an extruded composition that has passed through a die using a cooling gas stream.

However, the method for preparing blown films of ethylene aromatic hydrocarbon/conjugated diene block copolymers in the aforementioned patent No. US-5658526 only employs the circular mold and describes how to operate the blown film operation; it is not applicable for selectively bonding films and injection-molded products (e.g., manufacturing plastic products or products with similar properties).

Another common application is the molding of articles containing thin films and methods thereof, for example, Patent Cooperation Treaty No. WO-2014/203917, "Film, film molding method, mold, molding comprising film, and molding method therefor," which discloses a thin film, a method for molding a thin film, a mold for molding a thin film, a molded article containing a thin film, and a method thereof.

Continuing from the above, the film forming mold of the aforementioned patent No. WO-2014/203917 includes a lower mold, an upper mold, and a fixing frame. The lower mold has a protrusion, and the upper mold has a pushing component, which is positioned outside the protrusion when the mold is closed. Furthermore, the fixing frame fixes a film between the upper and lower molds, and the film forming mold shapes the film into a predetermined three-dimensional shape.

Continuing from the above, the film forming method of patent No. WO-2014/203917 employs the forming mold, which includes a heating step, a primary shaping step, and a secondary shaping step. In the heating step, while the pushing component of the upper mold is retracted, the film is fixed to the fixing frame and then heated to soften it. In the primary shaping step, when the upper and lower molds are closed, the pushing component advances and pushes the film at least outside the protrusion to perform primary shaping. In the secondary shaping step, using the pressure of the gas introduced from the upper mold side, after mold closing, the film is subjected to secondary shaping at least outside the protrusion of the lower mold, outside the protrusion.

Continuing from the above, the method for forming the molded article comprising a film according to patent number WO-2014/203917 involves printing on one surface of the film, and having a hard coating layer on one opposite side of the film to form a hard coating film. The method for forming the molded article comprising a film includes: a processing step, an embedding step, and a forming step.

Continuing from the above, patent No. WO-2014/203917 describes a process in which the hard coating film is processed corresponding to the cavity shape of an injection molding die. In the embedding step, the hard coating film is embedded within the cavity of the injection molding die, such that the hard coating surface contacts the cavity to form a film substrate. In the molding step, the film substrate is integrated into an injection molding material using injection molding to form a molded article.

However, the aforementioned patent No. WO-2014/203917's molded article containing a film and its molding method only employs the structure of the lower mold, upper mold, and fixing frame, and describes how to manufacture the molded article containing the film. It is not applicable for selectively combining films and injection-molded products (e.g., manufacturing plastic products or products with similar properties).

Another commonly used method for manufacturing PC film control panels and its molding die is exemplified by Republic of China Patent Announcement No. TW-I298288, "Method for Manufacturing a Curved PC Film Control Panel and its Molding Die," which discloses a method for manufacturing a curved PC film control panel and its molding die.

Continuing from the above, the method for manufacturing the curved PC film control panel of the aforementioned patent No. TW-I298288 includes: preparing a PC film prototype, wherein the PC film prototype includes an outer layer and an inner layer, and the PC film prototype is appropriately protruded at predetermined function operation and status display positions to form several status windows; and then a predetermined pattern or predetermined text is printed on a predetermined position on one of the outer layers of the PC film prototype.

Continuing from the above, the method for manufacturing the curved PC film control panel of the aforementioned patent No. TW-I298288 includes: a step of applying double-sided tape, applying the double-sided tape to the inner surface of the PC film prototype, and disposing a release liner on the double-sided tape to form a PC film prototype with double-sided tape applied, so that after the release liner is peeled off, the double-sided tape can be adhered to a predetermined surface of an object.

Continuing from the above, the method for manufacturing the curved PC film control panel of the aforementioned patent No. TW-I298288 includes: a heating and molding step, in which the PC film prototype with double-sided adhesive applied is placed into a molding die for heating and molding, and the molding die appropriately has a predetermined curved surface so as to appropriately shape the PC film prototype with double-sided adhesive applied into a predetermined curved surface, thereby forming a curved PC film prototype.

Continuing from the above, the method for manufacturing the curved PC film control panel of the aforementioned patent No. TW-I298288 includes: a demolding step, in which the curved PC film prototype is appropriately demolded from the molding mold to obtain a curved PC film control panel.

Continuing on, the molding die for the curved PC film control panel of the aforementioned patent No. TW-I298288 includes a female mold and a male mold, with the female mold suitably mating to the male mold. The female mold is made of a metal material and has an inner mold surface, which is suitably molded into a predetermined curved surface.

Continuing on the above, the male mold of the aforementioned patent No. TW-I298288 is made of a metal with good thermal conductivity. The male mold has an outer mold surface, which is appropriately shaped into a predetermined curved surface. The outer mold surface of the male mold mates with the inner mold surface of the female mold, and the male mold is appropriately provided with at least one heating hole at a predetermined position.

However, the manufacturing method and molding die of the curved PC film control panel in the aforementioned patent No. TW-I298288 only utilize the structure of the female mold and male mold and how to manufacture the curved PC film prototype. It is not applicable for selectively combining films and injection-molded products (e.g., manufacturing plastic products or products with similar characteristics), and it is unrelated to films and injection-molded products.

Another common method for vacuuming and adsorbing in-mold decorative molds and its in-mold decorative film adsorption device is exemplified by Republic of China Patent Publication No. TW-201309452, "Method for Vacuuming and Adsorbing in-mold Decorative Molds and In-mold Decorative Film Adsorption Device," which discloses an in-mold decorative film adsorption device and a method for vacuuming and adsorbing in-mold decorative molds.

Continuing from the above, the in-mold decorative film adsorption device of the aforementioned patent No. TW-201309452 includes several air holes and a suction device. The air holes penetrate a front end face, which is a flat end face. The air holes are symmetrically and uniformly distributed on the front end face, and each air hole is connected to a suction device at its other end.

Continuing from the above, the vacuuming and adsorption method for the in-mold decoration mold described in patent No. TW-201309452 involves: during the in-mold decoration process, an in-mold decoration film adsorption device is attached to a film, and the film is adhered and fixed to the adsorption device using an adsorption force provided by the in-mold decoration film adsorption device.

Continuing from the above, the vacuuming and adsorption method for the in-mold decorative mold described in patent No. TW-201309452 involves the following: Several air holes are provided through the front end face of the in-mold decorative film adsorption fixture. When fixing the film, one end of each air hole is correspondingly placed against the film, and then the other end of each air hole is connected to a vacuuming device so that the vacuuming device draws out gas, thus providing an adsorption and fixing force on the film.

However, the vacuuming and adsorption method for the in-mold decorative mold described in patent No. TW-201309452 only utilizes the structure of the in-mold decorative film adsorption fixture and the vacuuming device, and how the film is adsorbed and fixed on the in-mold decorative film adsorption fixture to directly perform various surface processing operations (e.g., film printing, film high-pressure molding, film punching, or other similar surface processing operations). It is not suitable for bonding and fixing the film to the mold or its accessories (e.g., male mold, female mold, mold core, or other mold accessories), thus having the disadvantage of complex processing operations (e.g., mold combined with in-mold decorative film adsorption fixture, mold combined with vacuuming device, or other complex mold combination designs).

Although the aforementioned US Patents US-5098281, US Patent US-5658526, PCT Patent No. WO-2014/203917, ROC Patent Publication No. TW-I298288, and ROC Patent Publication No. TW-201309452 have disclosed various conventional molding dies used in bonding films, there is inevitably a need for further improvement in order to provide a transparent object structure for bonding films and its manufacturing method.

Clearly, the aforementioned US Patent Nos. US-5098281, US-5658526, PCT Patent Nos. WO-2014/203917, Republic of China Patent Announcement Nos. TW-I298288 and TW-201309452 are merely for reference and explanation of the current state of technological development in this invention, and are not intended to limit the scope of this invention.

Figure 2 is a block diagram illustrating a process for manufacturing a composite film object according to a preferred embodiment of the present invention. Referring to Figures 1, 2, and 3, for example, the manufacturing method of the composite film object according to a preferred embodiment of the present invention includes step S1: First, for example, at least one airflow channel 11 is disposed on a mold core 10 using appropriate technical means (e.g., automated, semi-automated, or manual methods).
