Description
本創作係有關於一種使用水壓及蒸汽壓的成形方法及一成形裝置。The present invention relates to a forming method using water pressure and vapor pressure and a forming device.
當人造皮或裝飾箔膜被形成為高級內裝的表面材料及被施用在車輛,電子部件,及類此者的外部材料時,會使用成形方法(譬如像是,真空成形,熱壓成形,低壓注模,及***成形)。When the artificial leather or decorative foil film is formed into a surface material of a high-grade interior and applied to an exterior material of a vehicle, an electronic component, and the like, a forming method (such as, for example, vacuum forming, hot press forming, Low pressure injection molding, and insert molding).
然而,在真空成形的例子中,一材料可藉由加熱而被變形或氣泡會在一變形處理期間發生。又,一深抽成形物件在與一模具有非均勻的接觸時會擴張。在此例子中,該物件在成形處理之後的厚度會變得不均勻。再者,當印刷圖案存在於該物件的表面上時,該印刷圖案會因為該不均勻的成形而無法與該物件一起同在焦點上。However, in the case of vacuum forming, a material may be deformed by heating or bubbles may occur during a deformation process. Also, a deep drawn article expands when it is in non-uniform contact with a mold. In this example, the thickness of the article after the forming process may become uneven. Furthermore, when a printed pattern is present on the surface of the article, the printed pattern may not be in focus with the article due to the uneven shaping.
在liebling模製例子中,產生高壓是很困難的,且一箔膜受到一高壓空氣而變成細長形。因此,會產生像是該箔膜白化(whitening)的問題。In the liebling molding example, it is difficult to generate high pressure, and a foil film is elongated by a high pressure air. Therefore, there arises a problem that the foil film is whitening.
低壓注模是一種熔融樹脂在其被射出的同時即被模製 的方法。然而,因為該樹脂的流動性不足且該高溫樹脂與該模具直接接觸,所以該模具會受損。又,該模具的厚度不均勻是因為在該模具內的有壓力差,且該模具的表面會白化說該表面沒有被加熱。Low-pressure injection molding is a molten resin that is molded while it is being ejected. Methods. However, since the fluidity of the resin is insufficient and the high temperature resin is in direct contact with the mold, the mold may be damaged. Also, the thickness of the mold is not uniform because of a pressure difference in the mold, and the surface of the mold is whitened to say that the surface is not heated.
在熱壓成形的例子中,以上所述的問題都會發生,且無法形成具有一底切部件的複雜形狀。In the case of hot press forming, the problems described above occur, and a complicated shape having an undercut member cannot be formed.

A variety of decorative foil or artificial leather for the interior and exterior materials of this person. In the present creation, when the foil film is formed as a surface material, the shape including a water pressure or vapor pressure generator is used. Therefore, a uniform high pressure state can be effectively formed in which a uniform pressure can be temporarily applied to the entire object inside the mold. In one embodiment, the water pressure or vapor pressure generator according to the present creation may be a water or steam generator. The method can include a uniform high pressure condition in the mold and by injecting water or steam into the mold and injecting the water or steam into the mold to use the pressure to shape the item to be formed (eg, Foil film) is formed.
在依據本創作的成形方法中,使用例如圖1所示的成形裝置。然而,示於圖1中的成形裝置只是本創作的一個例子。亦即,除了圖1所示的成形裝置之外,任何成形裝置都可被使用,只要它包括一水壓或蒸汽壓產生器及能夠使用該產生器所產生的水壓或蒸汽壓來將一物件成形即可。In the forming method according to the present invention, for example, a forming device as shown in Fig. 1 is used. However, the forming apparatus shown in Fig. 1 is only an example of the present creation. That is, any forming device other than the forming device shown in Fig. 1 can be used as long as it includes a water pressure or vapor pressure generator and a water pressure or vapor pressure which can be generated using the generator. The object can be formed.
如圖1所示,依據本創作的成形裝置包括一水壓或蒸汽壓產生器1,一入口/出口埠2,該水壓或蒸汽壓產生器所產生的水壓或蒸汽壓可經由該入口/出口埠被印入到該模具中或從該模具中排出,及一模具3其連接至該入口/出口埠2。As shown in Figure 1, the forming apparatus according to the present invention comprises a water pressure or vapor pressure generator 1, an inlet/outlet port 2 through which the water pressure or vapor pressure generated by the water pressure or vapor pressure generator can pass. The /out port is printed into or discharged from the mold, and a mold 3 is connected to the inlet/outlet port 2.
包括在圖1所示的成形裝置內的該產生器1可以是一種藉由產生水以產生能夠將一物件成形的水壓並將水壓注入該模具3中的裝置;一種藉由將被加熱的及/或被加壓的水注入該模具3中以產生能夠將一物件成形的水壓的裝 置;或一種藉由將水加熱及/或加壓以產生蒸汽並將該蒸汽注入該模具3中以產生能夠將一物件成形的蒸汽壓的裝置。The generator 1 included in the forming apparatus shown in Fig. 1 may be a device for generating water pressure capable of forming an object and injecting water into the mold 3 by generating water; And/or pressurized water is injected into the mold 3 to produce a water pressure capable of forming an object. Or a device for generating steam by injecting and/or pressurizing water to inject steam into the mold 3 to produce a vapor pressure capable of shaping an object.
該加熱或加壓的範圍並沒有特別的限制,只要被安裝在該模具內的物件可被成形即可。例如,該產生器1所產生之將被用來將一物件成形的該水(或水壓)或蒸汽(或蒸汽壓)可被加壓至約150至約2000巴(bar),較佳地約150至約1000巴,更佳地為約150至約500巴,及最佳地約150至約200巴的壓力。當該壓力小於150巴時,該被產生的水壓或蒸汽壓將不足以將該物件成形。當該壓力超過2000巴時,不當的變形或損傷會發生在該物件上。The range of the heating or pressurization is not particularly limited as long as the article mounted in the mold can be formed. For example, the water (or water pressure) or steam (or vapor pressure) produced by the generator 1 that will be used to shape an article may be pressurized to between about 150 and about 2000 bars, preferably From about 150 to about 1000 bar, more preferably from about 150 to about 500 bar, and most preferably from about 150 to about 200 bar. When the pressure is less than 150 bar, the resulting water pressure or vapor pressure will not be sufficient to shape the article. When the pressure exceeds 2000 bar, improper deformation or damage can occur on the object.
在一實施例中,由該產生器1所產生之將被用來將一物件成形的該水(或水壓)或蒸汽(或蒸汽壓)可被加熱至約30至約250℃,較佳地為約30至約180℃,的溫度。當該溫度小於30℃時,該被產生的水壓或蒸汽壓將不足以將該物件成形。當該溫度超過250℃時,不當的變形或損傷會發生在該物件上。In one embodiment, the water (or water pressure) or steam (or vapor pressure) produced by the generator 1 to be used to shape an article may be heated to between about 30 and about 250 ° C, preferably. The ground is at a temperature of from about 30 to about 180 °C. When the temperature is less than 30 ° C, the resulting water pressure or vapor pressure will not be sufficient to shape the article. When the temperature exceeds 250 ° C, improper deformation or damage may occur on the article.
包括在圖1所示的裝置內的該入口/出口埠2可用來將該產生器所產生的該水(或水壓)或蒸汽(或蒸汽壓)引入到該模具3中。在一實施例中,該埠口2的一側可被接至該產生器1,而其另一側則可被連接至該模具3。The inlet/outlet port 2 included in the apparatus shown in Fig. 1 can be used to introduce the water (or water pressure) or steam (or vapor pressure) generated by the generator into the mold 3. In an embodiment, one side of the cornice 2 can be connected to the generator 1 and the other side can be connected to the mold 3.
包括在圖1所示的裝置內的該模具3是一物件4被來自該產生器1的水壓或蒸汽壓成形的所在處。在一實施例中,如圖1所示,該模具可包括一上模31及一下模32。The mold 3 included in the apparatus shown in Fig. 1 is where an object 4 is formed by water pressure or vapor pressure from the generator 1. In an embodiment, as shown in FIG. 1, the mold may include an upper mold 31 and a lower mold 32.
該上模31可被連接至該入口/出口埠2且具有一孔,經由該入口/出口埠2被引入的水或蒸汽可經由該孔被注入該模具3內。又,該下模32具有一不平處(成形不規則性)被形成於其內。該不平處(unevenness)的形狀可根據該物件4將被成形的形狀來定。The upper die 31 can be connected to the inlet/outlet port 2 and has a hole through which water or steam introduced via the inlet/outlet port 2 can be injected into the mold 3. Further, the lower mold 32 has an uneven portion (forming irregularity) formed therein. The shape of the unevenness can be determined according to the shape in which the article 4 will be formed.
在一實施例中,該將被成形的物件可被放置在該上模31與該下模32之間。In an embodiment, the article to be formed may be placed between the upper die 31 and the lower die 32.
該模具3可進一步包括一固定件34用來固定該將被成形的物件4。在此例子中,該固定件34的種類並沒有特別的限制。亦即,任何固定件都可被使用,只要它可以將被安裝在該模具3內的物件4固定即可。例如,該固定件34可以是一用矽或撓性胺基甲酸脂製成的O型環。因此,該物件可被該固定件34更穩固地安裝在該模具3內。因此,可更精確地實施該成形處理。The mold 3 may further include a fixing member 34 for fixing the article 4 to be formed. In this example, the kind of the fixing member 34 is not particularly limited. That is, any fixing member can be used as long as it can fix the article 4 mounted in the mold 3. For example, the fastener 34 can be an O-ring made of tantalum or flexible urethane. Therefore, the article can be more stably installed in the mold 3 by the fixing member 34. Therefore, the forming process can be performed more accurately.
該模具3可包括一或多個排氣溝槽33,其可防止該模具3的內部在水或蒸汽從該入口/出口埠2被引入到該模具3內以產生水壓或蒸汽壓時被過度地加壓。在一實施例中,該等排氣溝槽33可被形成在下模32上。該等排氣溝槽33可被連接至一可將空氣從該模具中排出之典型的排氣單元(例如,一真空幫浦,或類此者)。The mold 3 may include one or more exhaust grooves 33 that prevent the interior of the mold 3 from being introduced into the mold 3 from water or steam when water or steam is introduced from the inlet/outlet port 2 to generate water pressure or vapor pressure. Excessively pressurized. In an embodiment, the exhaust grooves 33 may be formed on the lower die 32. The exhaust channels 33 can be connected to a typical exhaust unit (e.g., a vacuum pump, or the like) that can evacuate air from the mold.
因為形成有這些排氣溝槽33,所以該模具的內部在成形期間就不會被過度地加壓。又,如果有必要的話,該模具的內部可在使用該水壓或蒸氣壓的該成形處理間被形成空虛的狀態(vacuous condition),這可更有效率地實施 該成形處理。Since these exhaust grooves 33 are formed, the inside of the mold is not excessively pressurized during forming. Further, if necessary, the inside of the mold can be formed into a vacuum condition between the forming processes using the water pressure or vapor pressure, which can be carried out more efficiently. This forming process.
如圖1所示,依據本創作的該成形裝置可額外地包括一撓性的輔助件5其被附裝至該上模31的下端,使得該撓性的輔助件5被放置在該上模31與該物件4之間。該撓性的輔助件5可用一撓性或可擴展的材料來製造,該材料可被該產生器1所產生的該水壓或該蒸汽壓輕易地變形。例如,氯丁二烯橡膠,矽膠,或撓性的胺基甲酸酯都可被用作為該撓性的輔助件5。當該成形裝置包括該撓性的輔助件5時,可防止該物件4被該水壓或該蒸汽壓損傷。又,即使是在一物件具有孔洞而不能使用真空成形的例子中,仍可有效地實施該成形處理。As shown in Fig. 1, the forming apparatus according to the present invention may additionally include a flexible auxiliary member 5 attached to the lower end of the upper mold 31 such that the flexible auxiliary member 5 is placed on the upper mold. 31 is between the object 4. The flexible auxiliary member 5 can be manufactured from a flexible or expandable material which can be easily deformed by the water pressure or the vapor pressure generated by the generator 1. For example, a neoprene rubber, a silicone rubber, or a flexible urethane can be used as the flexible auxiliary member 5. When the forming device includes the flexible auxiliary member 5, the article 4 can be prevented from being damaged by the water pressure or the vapor pressure. Further, even in the case where an object has a hole and vacuum molding cannot be used, the forming process can be effectively performed.
因此,當用撓性或可擴展的材料製造的該輔助件5被設置時,該產生器1所產生的該水壓或該蒸汽壓可透過該輔助件5對該物件加壓用以將該物件成形。如果有必要的話,該壓力可被直接施加至該物件上來實施該成形處理而不透過該撓性輔助件5。Therefore, when the auxiliary member 5 made of a flexible or expandable material is disposed, the water pressure or the vapor pressure generated by the generator 1 can pressurize the article through the auxiliary member 5 to apply the The object is shaped. If necessary, the pressure can be applied directly to the article to effect the forming process without passing through the flexure aid 5.
一種使用上述的裝置來成形一物件的方法將於下文中加以描述。A method of forming an article using the apparatus described above will be described below.
首先,如圖1所示,該將被成形的物件4被固定在該上模31與該下模32之間。First, as shown in FIG. 1, the article 4 to be formed is fixed between the upper mold 31 and the lower mold 32.
然後,如圖2所示,水(或水壓)或蒸汽(或蒸汽壓)被該產生器產生且被注入到該模具內。當此一處理被實施時,一均勻的壓力被該產生器1所產生之水壓或蒸氣壓施加至整個物件4上。因此,該物件4被朝向下模32移 動。該被移動的物件4順著形成在該模具內的不平處變形。因此,該物件可被成形為圖3所示。在此處理中,空氣可經由排氣溝槽33被適當地排出,或如果有必要的話,該模具的內部可被形成空虛的狀態以提高成形效率。Then, as shown in Fig. 2, water (or water pressure) or steam (or vapor pressure) is generated by the generator and injected into the mold. When this treatment is carried out, a uniform pressure is applied to the entire object 4 by the water pressure or vapor pressure generated by the generator 1. Therefore, the object 4 is moved toward the lower mold 32 move. The moved object 4 is deformed along the unevenness formed in the mold. Therefore, the article can be shaped as shown in FIG. In this process, air can be appropriately discharged via the exhaust groove 33, or if necessary, the inside of the mold can be formed in an empty state to improve the forming efficiency.
因為使用該產生器1所產生之水壓或蒸氣壓,所以一均勻的壓力可被施加至整個將被程形的該物件4上。因此,可以防止成形處理之後的厚度變動及類此者等問題的發生。Since the water pressure or vapor pressure generated by the generator 1 is used, a uniform pressure can be applied to the entire object 4 to be shaped. Therefore, it is possible to prevent the thickness variation after the forming process and the occurrence of problems such as this.
該物件4在很短的時間內被該產生器1所產生之水壓或蒸氣壓均勻地貼附至該下模內的不平處上,或如果有需要的話,水壓或蒸汽壓可被加熱及/或加壓,然後被完全地成形為如圖3所示。The article 4 is evenly attached to the unevenness in the lower mold by the water pressure or vapor pressure generated by the generator 1 in a short period of time, or the water pressure or vapor pressure can be heated if necessary. And/or pressurized, then fully formed as shown in FIG.
根據本創作的成形方法,當該可在有需要時被加熱及/或加壓的水壓或蒸汽壓被用來施加一恆定的壓力於該待成形的整個物件上,因此可有效地形成一無法用傳統的成形方法(如真空成形)製造的底切部件(undercut parts),及其它需要小心地形成的部件。又,本創作的方法可有效地防止成形處理之後的厚度偏差,厚度偏差會發生在真空成形處理中。再者,本創作的方法可防止該物件白化。According to the forming method of the present invention, when the water pressure or vapor pressure which can be heated and/or pressurized as needed is used to apply a constant pressure to the entire object to be formed, it is possible to effectively form a Undercut parts that cannot be made using conventional forming methods such as vacuum forming, and other parts that need to be carefully formed. Further, the method of the present invention can effectively prevent the thickness deviation after the forming process, and the thickness deviation occurs in the vacuum forming process. Furthermore, the method of the creation prevents the object from being whitened.

As shown in Fig. 4A, in the sample formed by the vacuum forming method, its exterior was damaged, in which a printed line was broken and a pattern was spread. However, in the sample formed by the forming method of the present invention, one The pattern exists in an effective area and an edge portion is clearly exposed.
本創作係有關於一種成形裝置其包括一水壓或蒸汽壓產生器及一模具其與該水壓或蒸汽壓產生器相連通且具有一不平處,藉由該不平處該物件可被該產生器所產生的水壓或蒸汽壓成形。The present invention relates to a forming apparatus comprising a water pressure or vapor pressure generator and a mold connected to the water pressure or vapor pressure generator and having an unevenness, by which the object can be produced by the unevenness The water pressure or vapor pressure generated by the device is formed.
在一實施例中,依據本創作的該成形裝置可以是一用來將上文中提到的箔膜成形的成形裝置。In an embodiment, the forming device according to the present invention may be a forming device for forming the foil film mentioned above.
依據本創作之成形裝置的特殊配置並沒有被特別地限制。例如,上文中所描述之示於圖1中的裝置即可被使用。The special configuration of the forming device according to the present invention is not particularly limited. For example, the apparatus shown in Figure 1 described above can be used.
亦即,依據本創作的成形裝置可包括如上文中所描述之該模具其具有一與該產生器連通的上模及一其內形成有不平處之下模。That is, the forming apparatus according to the present invention may include the mold as described above having an upper mold in communication with the generator and a lower mold in which the unevenness is formed.
又,依據本創作的成形裝置可包括如上文中所描述之形成在該下模上的排氣溝槽。Further, the forming apparatus according to the present invention may include an exhaust groove formed on the lower mold as described above.

又,依據本創作的成形裝置可額外地包括一O型環,該模具可藉由該O型環固定一物件。該O型環可用矽或撓性的胺基甲酸脂來製造。Further, the forming apparatus according to the present invention may additionally include an O-ring by which an object can be fixed by the O-ring. The O-ring can be made of hydrazine or a flexible urethane.
根據本創作,一在必要時可被適當地加熱及/或加壓的水壓或蒸汽壓被短暫地(momentarily)注入到一模具內且一物件被該水壓或蒸汽壓所產生的壓力成形。因此,可顯著地縮短處理時間。又,根據本創作,一需要被小心地成形的部件及一無法用傳統的方法加以精確地成形的底切部件。又,即使是當印刷物或印刷圖案被形成在一物件上,本創作可獲得一模製物其上的印刷物或印刷圖案被形成在準確的位置上。According to the present invention, a water pressure or a vapor pressure which can be appropriately heated and/or pressurized as necessary is momentarily injected into a mold and an object is formed by the pressure generated by the water pressure or vapor pressure. . Therefore, the processing time can be significantly shortened. Further, according to the present creation, there is a need for a member that is carefully formed and an undercut member that cannot be accurately formed by a conventional method. Further, even when a printed matter or a printed pattern is formed on an object, the present invention can obtain a printed matter or a printed pattern on a molded object formed at an accurate position.
根據本創作,一均勻的壓力可藉由使用該水壓或蒸汽壓被短暫地產生在一物件的整個面積上。因此,本創作可防止缺陷的形成,該缺陷是因為當一物件的面積在傳統的方法中增加時施加在每單位面積上的壓力減小或不均勻而產生的。又,本創作可用一低很多的成本且透過一比用機械方式提高壓力的傳統方法容易許多的方法來實施高壓。According to the present creation, a uniform pressure can be instantaneously generated over the entire area of an object by using the water pressure or vapor pressure. Therefore, the present invention can prevent the formation of defects which are caused by a decrease or unevenness in pressure applied per unit area when the area of an object is increased in a conventional method. Moreover, this creation can be implemented at a much lower cost and by a conventional method that increases the pressure mechanically, and the high pressure is easily implemented in many ways.
根據本創作,可防止在一成形處理之後白化,熱損傷及發泡的發生在一物件上,如一箔膜上。又,本創作可在一物件與一模具接觸時減小因為溫差所造成的膨脹係數上的差異。因此,本創作可防止在成形處理之後因為差異或濃度的問題所造成之皺紋及厚度偏差。According to the present invention, whitening, heat damage and foaming can be prevented from occurring on an object such as a foil after a forming process. Moreover, the present invention can reduce the difference in expansion coefficient caused by the temperature difference when an object is in contact with a mold. Therefore, the present invention can prevent wrinkles and thickness deviations caused by problems of difference or concentration after the forming process.
根據本創作,因為不再需要在真空成形方法中所需要的夾具,所以空間效率可提高,且材料的損失可被顯著地減少。又,一用來固定一物件的輔助單元,譬如一固定單元(例如,夾具),或一在傳統成形方法中需要的加熱單元,都不再需要,且一單一蒸汽或水產生器可被連接至數 個成形單元(例如,模具)。因此,本創作可提高工作場所的空間利用並降低整體的投資成本。According to the present creation, since the jig required in the vacuum forming method is no longer required, the space efficiency can be improved, and the loss of material can be remarkably reduced. Further, an auxiliary unit for fixing an object, such as a fixed unit (for example, a jig), or a heating unit required in a conventional forming method, is no longer required, and a single steam or water generator can be connected. Count Forming units (eg, molds). Therefore, this creation can increase the space utilization of the workplace and reduce the overall investment cost.
