本發明提供一種一片式防水鞋面的製造方法，包含下列步驟：請參照第1圖所示，將至少一發泡片1置於一軟質模具2，使該發泡片1的一塑形面11與該軟質模具2的一轉印面21接觸。詳言之，本實施例的發泡片1可以具有一發泡層1a連接一內面層1b，該發泡層1a可以是由聚氨酯(Polyurethane，PU)或熱塑性聚氨酯(Thermoplastic Polyurethane，TPU)等材質發泡而成，該發泡層1a未連接該內面層1b的表面可以形成該塑形面11。亦即，該發泡層1a可以被該軟質模具2塑形，並形成鞋面產品的外表面，且該塑形面11在被塑形前原則上係呈平坦狀，故該發泡層1a可按 鞋面設計需求而選用適當的厚度，例如鞋面產品的外表面需呈現較多高低層次的立體造型時，應選用較厚的發泡層1a來進行塑形，反之則可選擇較薄者；整體而言，該發泡層1a較常選用1~1.6mm左右的厚度，但並不以此為限。又，該發泡層1a的顏色較佳為淺色，使該塑形面11能較容易套色(容後詳述)。該內面層1b則是鞋面產品的內裡，故可以依照舒適性或保溫效果等需求選用合適的材質。 The present invention provides a method for manufacturing a one-piece waterproof shoe upper, which includes the following steps: Please refer to Figure 1, place at least one foam sheet 1 in a soft mold 2, so that a shaping surface of the foam sheet 1 11 is in contact with a transfer surface 21 of the soft mold 2 . Specifically, the foam sheet 1 of this embodiment may have a foam layer 1a connected to an inner surface layer 1b. The foam layer 1a may be made of polyurethane (PU) or thermoplastic polyurethane (TPU). The plastic material is foamed, and the surface of the foam layer 1a that is not connected to the inner surface layer 1b can form the shaping surface 11. That is to say, the foam layer 1a can be shaped by the soft mold 2 and form the outer surface of the shoe upper product, and the shaping surface 11 is flat in principle before being shaped, so the foam layer 1a Can be pressed The appropriate thickness should be selected according to the design requirements of the shoe upper. For example, when the outer surface of the shoe upper product needs to present more three-dimensional shapes of high and low levels, a thicker foam layer 1a should be used for shaping, and vice versa, a thinner one can be selected; Generally speaking, the thickness of the foam layer 1a is usually about 1 to 1.6 mm, but it is not limited to this. In addition, the color of the foam layer 1a is preferably light, so that the shaping surface 11 can be easily colored (described in detail later). The inner surface layer 1b is the inner lining of the upper product, so appropriate materials can be selected according to requirements such as comfort or thermal insulation effect.
該軟質模具2需具備軟質與可導電之特性，例如可選用低阻抗的導電矽膠模具，且矽膠的硬度約可以為蕭氏硬度50~90度。該軟質模具2的轉印面21係具有立體造型，用以於塑形後使該發泡片1的塑形面11具有相應的立體造型。其中，該轉印面21上的立體造型可選擇翻印自至少一母版鞋面，該母版鞋面可以為呈攤平狀的習知鞋面，該母版鞋面可以具有大至區塊設計、品牌標示或裝飾物，小至皮革紋路或縫線痕跡等飾紋的多元立體造型。 The soft mold 2 needs to be soft and conductive. For example, a low-resistance conductive silicone mold can be used, and the hardness of the silicone can be about 50 to 90 degrees Shore hardness. The transfer surface 21 of the soft mold 2 has a three-dimensional shape, so that the shaping surface 11 of the foam sheet 1 has a corresponding three-dimensional shape after shaping. Among them, the three-dimensional shape on the transfer surface 21 can be copied from at least one master shoe upper. The master shoe upper can be a conventional shoe upper in a flat shape, and the master shoe upper can have a large to block design. , brand logos or decorations, and diverse three-dimensional shapes with decorative patterns as small as leather textures or stitching marks.
請參照第2圖所示，利用高週波加熱法使該發泡片1受熱軟化，另施加壓力將該軟質模具2與該發泡片1密合，使該發泡片1的塑形面11具有與該軟質模具2的轉印面21相對應的立體造型。詳言之，本實施例可選擇利用該軟質模具2的導電性，應用高週波加熱原理使該發泡片1受熱而軟化，特別是該發泡片1接觸於該軟質模具2的塑形面11處。其中，可以是先讓該發泡片1軟化至預定程度(可利用加熱時間控制)，再施加壓力使該軟質模具2與該發泡片1密合；或者，也可以一邊加熱軟化該發泡片1，一邊施加壓力使該軟質模具2與該發泡片1密合。 Referring to Figure 2, a high-frequency heating method is used to soften the foam sheet 1, and pressure is applied to tightly contact the soft mold 2 with the foam sheet 1, so that the molding surface 11 of the foam sheet 1 It has a three-dimensional shape corresponding to the transfer surface 21 of the soft mold 2 . In detail, this embodiment can choose to utilize the conductivity of the soft mold 2 and apply the high-frequency heating principle to heat and soften the foam sheet 1 , especially when the foam sheet 1 is in contact with the shaping surface of the soft mold 2 11 places. Among them, the foamed sheet 1 can be softened to a predetermined degree (can be controlled by the heating time), and then pressure can be applied to make the soft mold 2 and the foamed sheet 1 closely adhere to each other; or, the foamed sheet 1 can also be softened by heating. While applying pressure to the sheet 1, the soft mold 2 and the foam sheet 1 are closely connected.
例如但不限制地，本實施例密合該軟質模具2與該發泡片1的壓力約可以為500~1500kg/cm2，塑形該塑形面11的持壓時間則只要大約10~30秒，相當快速。如此，軟化後的該塑形面11可在與該轉印面21相密合 的時間裡，充分地變形成符合該轉印面21上立體造型的型態。 For example, but not limited to, the pressure for tightly sealing the soft mold 2 and the foam sheet 1 in this embodiment can be about 500~1500kg/cm 2 , and the pressure holding time for shaping the shaping surface 11 is only about 10~30 Seconds, pretty fast. In this way, the softened shaping surface 11 can be fully deformed into a shape conforming to the three-dimensional shape on the transfer surface 21 during the time when it is in close contact with the transfer surface 21 .
請參照第3圖所示，自該軟質模具2取下冷卻後的該發泡片1，以製得至少一個塑形成品P。其中，較佳可選擇使該發泡片1在冷卻過程中維持與該軟質模具2密合；亦即，可以在停止加熱該發泡片1後，仍持續施加壓力以維持該軟質模具2與該發泡片1密合，而此階段的壓力可以與塑形時的壓力相同(約500~1500kg/cm2)或稍加減壓。又，前述冷卻過程的持壓時間約可以為3~5秒，以避免該發泡片1在冷卻過程中翹曲變形。 Referring to Figure 3, the cooled foam sheet 1 is removed from the soft mold 2 to produce at least one molded product P. Among them, it is better to choose to keep the foam sheet 1 in close contact with the soft mold 2 during the cooling process; that is, after stopping heating the foam sheet 1, continue to apply pressure to maintain the soft mold 2 and the soft mold 2. The foam sheet 1 is tightly sealed, and the pressure at this stage can be the same as the pressure during shaping (about 500~1500kg/cm 2 ) or slightly reduced. In addition, the pressure holding time of the aforementioned cooling process can be about 3 to 5 seconds to prevent the foam sheet 1 from warping and deforming during the cooling process.
如此，所製得的該塑形成品P可以在其塑形面11充分呈現出仿造該母版鞋面的效果，無論是鞋面的造型設計、品牌標示、裝飾物，甚至是皮革紋路或縫線痕跡等，都能細緻地呈現出來。此外，由該塑形成品P經後續程序處理而製得的一片式防水鞋面，還能因為整體呈一片式地相連而沒有間隙或縫線孔隙，故能達到完全防水的效果。另一方面，該一片式防水鞋面可以呈攤平狀，故可便於將多個一片式防水鞋面堆疊放置，並做好密封包裝以杜絕潮氣，可以集中於一地生產，再運輸至多地或多國進行後續製鞋流程，對製造者而言，在包裝及運送面上均十分便利且能有效降低成本。 In this way, the molded product P can fully exhibit the effect of imitating the master shoe upper on its molding surface 11, whether it is the shape design, brand logo, decoration, or even leather texture or stitching of the shoe upper. Line traces, etc., can be presented in detail. In addition, the one-piece waterproof shoe upper made from the molded product P through subsequent processes can also achieve a completely waterproof effect because the whole is connected in one piece without gaps or seam holes. On the other hand, the one-piece waterproof shoe upper can be laid out flat, so multiple one-piece waterproof shoe uppers can be stacked and sealed and packaged to prevent moisture. Production can be concentrated in one place and then transported to multiple places. Or the subsequent shoemaking process can be carried out in multiple countries. For manufacturers, it is very convenient in terms of packaging and transportation and can effectively reduce costs.
此外，自該軟質模具2取下冷卻後的該發泡片1之後，還可以對該塑形成品P的該塑形面11噴印圖樣(圖未繪示)，使最後的一片式防水鞋面可以在其外表面呈現具有不同色彩或具有特定的品牌標示或其他裝飾物等型態。另，本實施例還可以選擇利用環保色料進行噴印，如此，可以在維持該塑形成品P之美觀性的同時，避免色料中的有害溶劑揮發而傷害操作人員的健康及環境。在其他實施例中，亦可選擇在將該發泡片1置於該軟質模具2之前，先於該塑形面11噴印圖樣。 In addition, after removing the cooled foam sheet 1 from the soft mold 2, a pattern (not shown) can be printed on the molding surface 11 of the molded product P to make the final one-piece waterproof shoe The surface can have different colors or have specific brand logos or other decorations on its outer surface. In addition, in this embodiment, you can also choose to use environmentally friendly colorants for printing. In this way, while maintaining the aesthetics of the molded product P, you can avoid harmful solvents in the colorants from volatilizing and harming the operator's health and the environment. In other embodiments, you can also choose to print a pattern on the shaping surface 11 before placing the foam sheet 1 on the soft mold 2 .
值得一提的是，本發明並不限制該軟質模具2的轉印面21上的立體造型是如何成型的，以下提供該軟質模具2的其中一種製造方法，但 並不以此為限。請參照第4圖所示，首先，可準備一容器3，並將一母版鞋面4置入該容器3內；隨後可以於真空環境下將一膠狀溶液5倒入該容器3，使該膠狀溶液5能覆蓋該母版鞋面4達預定厚度；續可對該膠狀溶液5施加壓力至該膠狀溶液5固化，即可製得該軟質模具2。 It is worth mentioning that the present invention does not limit how the three-dimensional shape on the transfer surface 21 of the soft mold 2 is formed. One of the manufacturing methods of the soft mold 2 is provided below, but It is not limited to this. Please refer to Figure 4. First, a container 3 can be prepared and a master shoe upper 4 can be placed into the container 3; then a colloidal solution 5 can be poured into the container 3 in a vacuum environment. The colloidal solution 5 can cover the master shoe upper 4 to a predetermined thickness; then pressure can be applied to the colloidal solution 5 until the colloidal solution 5 solidifies, and the soft mold 2 can be produced.
詳言之，本實施例的A膠及該B膠可以在倒入該容器3前預先混合，並將其周遭環境抽真空(時間大約需要10~15分鐘)，以減少該膠狀溶液5中的氣泡；抽真空完成後再於真空環境下把該膠狀溶液5倒入該容器3內，藉以大幅減少後續成型的軟質模具2中具有氣泡所形成的空洞。此外，本實施例的膠狀溶液5中還可以混摻有一導電物質，使製得的軟質模具2能具有導電性，以便高週波的電流傳遞。 In detail, the A glue and the B glue in this embodiment can be pre-mixed before pouring into the container 3, and the surrounding environment can be evacuated (it takes about 10 to 15 minutes) to reduce the content of the colloidal solution 5. bubbles; after the vacuuming is completed, the colloidal solution 5 is poured into the container 3 under a vacuum environment, thereby greatly reducing the cavities formed by bubbles in the subsequent molding of the soft mold 2 . In addition, the colloidal solution 5 in this embodiment can also be mixed with a conductive substance, so that the soft mold 2 produced can be conductive to facilitate the transmission of high-frequency current.
另一方面，本實施例可以將一重物6置入該容器3內，並壓抵在該膠狀溶液5上方，以對該膠狀溶液5施加約3~5kg/cm2的壓力，使該膠狀溶液5能充分填入該母版鞋面4表面的立體造型隙縫，並經過大約6~24小時的固化時間，在該膠狀溶液5固化後將其自該容器3中取出，以獲得該軟質模具2。如此，請配合參照第1圖所示，該軟質模具2的轉印面21上即可具有與該母版鞋面4相對應的立體造型。除此之外，該軟質模具2還可在背對該轉印面21的另一面貼附一硬質金屬板(圖未繪示)，以強化該軟質模具2整體的結構強度。舉例而言，該硬質金屬板可以是一鋁板，具有輕質及提升該軟質模具2導電性的效果。 On the other hand, in this embodiment, a weight 6 can be placed into the container 3 and pressed against the colloidal solution 5 to exert a pressure of about 3~5kg/cm 2 on the colloidal solution 5 to make the colloidal solution 5 The colloidal solution 5 can fully fill the three-dimensional gaps on the surface of the master shoe upper 4, and after about 6 to 24 hours of solidification, the colloidal solution 5 is taken out from the container 3 to obtain The soft mold 2. In this way, as shown in FIG. 1 , the transfer surface 21 of the soft mold 2 can have a three-dimensional shape corresponding to the master shoe upper 4 . In addition, the soft mold 2 can also be attached with a hard metal plate (not shown) on the other side facing away from the transfer surface 21 to enhance the overall structural strength of the soft mold 2 . For example, the hard metal plate may be an aluminum plate, which is lightweight and has the effect of improving the conductivity of the soft mold 2 .
綜上所述，本發明的一片式防水鞋面的製造方法，可利用軟質模具與高週波加熱法提升對發泡片的塑形良率與精細度，使製得的一片式防水鞋面無接縫、無縫線孔隙而具有良好的防水性，且不會有因縫線斷裂而損壞的問題。此外，本發明的製程中可以省去拼接與縫製等步驟，不僅提升了生產效率，也大幅減少了人力成本而可降低生產成本。另一方面，當該軟質 模具上的立體造型係由母版鞋面翻印而來時，所製得的一片式防水鞋面上還能具有預定的凹凸的立體造型，甚至能精細呈現仿縫線痕跡或仿皮革紋路等飾紋，具有提升該一片式防水鞋面質感的功效。 In summary, the manufacturing method of the one-piece waterproof shoe upper of the present invention can use soft molds and high-frequency heating methods to improve the shaping yield and precision of the foam sheets, so that the one-piece waterproof shoe upper produced has no Seams, no seam holes and good waterproofing, and there will be no problem of damage due to seam breakage. In addition, the process of the present invention can eliminate steps such as splicing and sewing, which not only improves production efficiency, but also greatly reduces labor costs and reduces production costs. On the other hand, when the soft When the three-dimensional shape on the mold is copied from the master shoe upper, the resulting one-piece waterproof shoe upper can also have a predetermined concave and convex three-dimensional shape, and can even finely display imitation stitching marks or imitation leather textures. The pattern has the effect of improving the texture of the one-piece waterproof upper.
