Description

囊袋之製造方法及其模具Pouch manufacturing method and its mold

本發明係有關一種囊袋之製造方法及其模具，特別是指一種利用內凹式模具，以真空成型的方式生產可罩住耳朵之囊袋。The invention relates to a method for manufacturing a pouch and its mold, in particular to a pouch that can cover ears by vacuum molding using a concave mold.

請參閱第1、2圖所示，一耳罩10為中空環形結構，係為一耳罩式耳機20或打靶專用耳罩籠罩使用者耳朵部分，令使用者可隔絕外界噪音並盡情享用音樂，該耳罩10係由一中空環狀之襯墊以及一塑片14結合而成，該塑片14之一面與該襯墊結合，而另一面固定在該耳罩式耳機20上；該襯墊係包括一囊袋11，其具有一開放之連接部112以及可容置一海綿12之一容置空間111，而該連接部112上設有一黏性物質13可與該塑片14結合。Please refer to Figures 1 and 2, an earmuff 10 is a hollow ring structure, which is an earmuff earphone 20 or a special earmuff for the target to cover the ear part of the user, so that the user can isolate the external noise and enjoy the music, The earmuff 10 is formed by combining a hollow ring-shaped gasket and a plastic sheet 14, one surface of the plastic sheet 14 is combined with the gasket, and the other surface is fixed on the over-ear earphone 20; the gasket It includes a pouch 11 with an open connection portion 112 and an accommodating space 111 capable of accommodating a sponge 12, and a viscous substance 13 on the connection portion 112 can be combined with the plastic sheet 14.

請參閱第3、4圖所示，習知該囊袋11之製造方式包括：Please refer to Figures 3 and 4, the conventional manufacturing method of the bag 11 includes:

步驟1：準備一環形之成形模具70並置於一基座90上，而該基座90上沿該成形模具70之內外緣周圍設有複數氣孔91；Step 1: Prepare an annular forming mold 70 and place it on a base 90, and the base 90 is provided with a plurality of air holes 91 along the inner and outer edges of the forming mold 70;

步驟2：準備一可塑性之皮料60，經高溫後呈具可塑之柔軟狀；以及Step 2: Prepare a plastic skin 60, which is plastic and soft after high temperature; and

步驟3：透過該等氣孔91往下吸氣，將該皮料60貼合於該成形模具70上，此時該成形模具70與該皮料60間為真空狀，此為真空成型法。Step 3: Inhale downward through the air holes 91 to attach the leather 60 to the forming mold 70. At this time, the forming mold 70 and the leather 60 are in a vacuum state. This is a vacuum forming method.

步驟4：藉由該皮料60之可塑性，該皮料60往下貼合於該成形模具70上，進一步該皮料60被向上撐開塑形成一立體囊袋80。Step 4: By the plasticity of the leather material 60, the leather material 60 is attached to the forming mold 70 downward, and the leather material 60 is stretched upward to form a three-dimensional bag 80.

步驟5：接著廠商進行裁切、填裝該海綿12、黏貼該塑片14，即形成該耳罩10(請參閱第1圖所示)。Step 5: The manufacturer then cuts, fills the sponge 12, and sticks the plastic sheet 14 to form the earmuff 10 (see FIG. 1).

然，請再參閱第4、5圖所示，因該等氣孔91為往下吸氣抽真空，因此該立體囊袋80上受真空吸力影響，會貼緊該基座以及該成形模具70，導致在對應該等氣孔91處會形成複數氣孔壓痕84，進而影響該立體囊袋80之整體美觀；再來，因皮料為具有伸縮性之材質，當該立體囊袋80被撐開成形後，在該成形模具70上時其皮料60存有被撐開的張力，當冷卻後自該成形模具70上取下該立體囊袋80時，依據冷縮熱脹的原理，該立體囊袋80會自周圍的餘料整體收縮，造成其尺寸與原先設定不符，當該連接部112尺寸與原始設定不合時，會影響到與該塑片14結合的貼合度。However, please refer to Figures 4 and 5 again. Because the air holes 91 are sucked down and evacuated, the three-dimensional pouch 80 is affected by the vacuum suction, and will closely adhere to the base and the forming mold 70. As a result, a plurality of air hole indentations 84 are formed at the corresponding air holes 91, which affects the overall appearance of the three-dimensional bag 80; again, because the leather is a stretchable material, when the three-dimensional bag 80 is stretched to form After that, the leather 60 of the forming mold 70 has a stretched tension. When the three-dimensional pouch 80 is removed from the forming mold 70 after cooling, the three-dimensional pouch is based on the principle of cold shrinkage and thermal expansion. The bag 80 will shrink overall from the surrounding residual material, causing its size to be inconsistent with the original setting. When the size of the connecting portion 112 is different from the original setting, it will affect the fit of the plastic sheet 14.

緣此之故，習知該成形模具70在製造時會預留該立體囊袋80之收縮空間，但，無法保證每次該立體囊袋80收縮的幅度皆相同，因此仍然會有與該塑片14尺寸不合的情形發生。For this reason, it is known that the forming mold 70 will reserve the shrinkage space of the three-dimensional pouch 80 when it is manufactured, but there is no guarantee that the three-dimensional pouch 80 will contract the same amount each time, so there will still be The situation in which the size of the sheet 14 is not the same occurs.

請參閱第3至5圖所示，從該立體囊袋80的剖面圖可看出，成形的該立體囊袋80為底部開放之凹字結構，其具有兩峰81、一谷82，以及可填入該海綿14之一容置空間83，而該等峰81分別為一ㄇ字結構，因該谷82與該等峰81的交界處為該等氣孔91抽氣處，在真空成型過程中因具有吸力，因此該皮料60會貼緊該基座90，但是當成形後，該等氣孔91不再抽氣，該立體囊袋80之外緣沒有外力束縛，以及冷縮熱脹原理，該等峰81與該谷82的交界處邊緣會收縮成弧形，造成該立體囊袋80之連接部112尺寸之誤差。Please refer to FIGS. 3 to 5, as can be seen from the sectional view of the three-dimensional pouch 80, the formed three-dimensional pouch 80 is a concave structure with an open bottom, which has two peaks 81, a valley 82, and a One of the storage spaces 83 of the sponge 14 is filled, and the peaks 81 are respectively a letter-shaped structure, because the junction between the valley 82 and the peaks 81 is the exhausting place of the air holes 91, in the vacuum forming process Because of the suction force, the leather 60 will be close to the base 90, but after forming, the air holes 91 are no longer evacuated, the outer edge of the three-dimensional bag 80 is not constrained by external forces, and the principle of cold shrinkage and thermal expansion, The edge of the boundary between the peaks 81 and the valleys 82 shrinks into an arc, resulting in a size error of the connection portion 112 of the three-dimensional pouch 80.

緣此之故，因此要如何解決上述之問題，即為此行業相關業者亟欲研究之課題所在。For this reason, how to solve the above-mentioned problems is the subject that the industry-related industry is eager to study.

本發明之主要目的，在於提供一種囊袋之製造方法及其模具，利用一下凹式之成形模具，透過傳統真空成型方式產生一不受冷縮影響而尺寸變小之囊袋，進一步將該囊袋應用在籠罩耳朵之產品上，如耳罩式耳機或隔音耳罩。The main object of the present invention is to provide a method and a mold for manufacturing a pouch, using a concave forming mold to produce a pouch with a reduced size that is not affected by cold shrinkage through the traditional vacuum forming method, and further the pouch The bag is used on products that cover the ears, such as earmuff headphones or soundproof earmuffs.

為達上述之目的，其技術手段在於，該成形模具係由一中空環形之本體、一底座以及一結合於該底座中央上之柱體組合而成，而該本體與該底座以及該柱體間形成一成形凹槽，當一可塑性皮料受熱後，透過真空成型技術緊密貼合於該成形模具上成形，冷卻時，即在該成形凹槽內形成一囊袋，因該囊袋在成形時係完全固定於該成形凹槽內，且成形時受限於該成形模具為下凹式，該囊袋僅能就容置於該成形凹槽內的皮料進行收縮，因此皮料收縮幅度大為降低，且該囊袋開口為與一塑片結合之一連接部，其範圍受該成形模具所固定，因此提高該囊袋尺寸之精準度。To achieve the above purpose, the technical means is that the forming mold is composed of a hollow ring-shaped body, a base, and a column bonded to the center of the base, and the body is between the base and the column A forming groove is formed. When a plastic leather is heated, it is closely adhered to the forming mold by vacuum forming technology. When cooling, a bag is formed in the forming groove, because the bag is formed It is completely fixed in the forming groove, and the forming mold is limited to the concave type when forming. The bag can only shrink the leather contained in the forming groove, so the shrinkage of the leather is large For lowering, and the opening of the bladder is a connecting part combined with a plastic sheet, the range of which is fixed by the forming mold, thus improving the accuracy of the size of the bladder.

本發明之另一目的，在於避免於成形之該囊袋上出現真空抽氣的氣孔，以維持該囊袋之整體造型及美觀。Another object of the present invention is to avoid the occurrence of air holes for vacuum evacuation in the formed bag to maintain the overall shape and aesthetic appearance of the bag.

為達上述之目的，其技術手段在於，該成形模具之本體底部，係與該底座結合面設有複數凸塊，進而在兩元件間形成一環形氣室，當進行真空成型時，空氣會沿著該氣室均勻的自該成形模具底部側邊抽出，保持該囊袋之完整性以及維持美觀。To achieve the above purpose, the technical means is that the bottom of the body of the forming mold is provided with a plurality of bumps on the joint surface with the base, and then an annular air chamber is formed between the two elements. When vacuum forming, the air will move along The air chamber is drawn uniformly from the bottom side of the forming mold to maintain the integrity of the pouch and maintain its aesthetic appearance.

為便於 貴審查委員能對本發明之技術手段及運作過程有更進一步之認識與瞭解，茲舉例配合圖式，詳細說明如下。In order to facilitate your examination committee to have a better understanding and understanding of the technical means and operation process of the present invention, here is an example with the drawings, detailed description is as follows.

實施例Examples

請參閱第6至8圖所示，於本實施例中，進一步將該囊袋11加工成與該耳罩式耳機20結合之耳罩10(請參閱第2圖所示)，而本發明囊袋之製造方法包含以下步驟：Please refer to FIG. 6 to FIG. 8, in this embodiment, the pouch 11 is further processed into an earmuff 10 combined with the over-ear earphone 20 (see FIG. 2), and the pouch of the present invention The manufacturing method of the bag includes the following steps:

步驟1：於該基座90上準備一成形模具30，該成形模具30係由一中空環形之本體31、一底座32以及一柱體33所組成，其中該柱體33係利用複數鎖固元件34結合於該底座之32中央，而該本體31亦透過該等鎖固元件34與該底座32結合，並與該底座32以及柱體33間形成一成形凹槽35，令該成形模具30內部形成類似「山」字結構；進一步該本體31之底部，與該底座32相臨面係設有複數凸塊36，令該本體31與該底座32無法完全緊密結合，兩者之間會存有空隙，即形成一環形之環形氣室37，在真空成型時，空氣係從該環形氣室37環形的向外被抽走。Step 1: Prepare a forming mold 30 on the base 90. The forming mold 30 is composed of a hollow ring-shaped body 31, a base 32 and a cylinder 33, wherein the cylinder 33 utilizes a plurality of locking elements 34 is combined with the center of the base 32, and the body 31 is also combined with the base 32 through the locking elements 34, and a forming groove 35 is formed between the base 32 and the column 33 to make the forming mold 30 inside Forming a similar "mountain" structure; further, the bottom of the body 31 is provided with a plurality of bumps 36 adjacent to the base 32, so that the body 31 and the base 32 cannot be completely tightly combined, there will be The gap, that is, an annular air chamber 37 is formed. During vacuum forming, air is drawn away from the annular air chamber 37 in an annular shape.

步驟2：準備經高溫使塑化之該皮料60。Step 2: Prepare the leather 60 plasticized by high temperature.

步驟3：從該成形模具30之氣室37環形且均勻地從側邊將空氣抽走。Step 3: From the air chamber 37 of the forming mold 30, the air is evacuated uniformly from the side.

步驟4：將已塑化之該皮料60靠近該成形模具30，因受抽真空影響，該皮料30完全吸附於該成形模具30上，此時兩元件間形成真空狀態；而該皮料60貼緊於該成形凹槽35並延展塑形成該囊袋11。Step 4: Move the plasticized leather 60 close to the forming mold 30. Due to the influence of vacuum, the leather 30 is completely adsorbed on the forming mold 30. At this time, a vacuum state is formed between the two components; and the leather 60 clings to the forming groove 35 and stretches to form the pouch 11.

步驟5：成形後之該囊袋11因利用延展成形，因此自該成形模具30上取下後仍為柔軟、平面之布面結構，非習知製法出來之立體囊袋80結構(請參閱第4圖所示)；然，該囊袋11依據該成形模具30其形狀為一凹字形狀，其內具有該容置空間111。Step 5: After forming, the bladder 11 is formed by extension, so it is still a soft and flat cloth structure after being removed from the forming mold 30, and a three-dimensional bladder 80 structure that is not produced by conventional methods (see 4); however, the shape of the pouch 11 is a concave shape according to the forming mold 30, and the accommodating space 111 is provided therein.

步驟6：請參閱第1、2圖所示，於該囊袋11之容置空間111內填充如該海綿12、泡棉等軟質填充物後，再將該囊袋11開口之連接部112處附著上該黏性物質13，即形成該耳罩10，即透過與之連接之該塑片14固定於一可罩住耳朵之物件上，該可罩住耳朵之物件包括：該耳罩式耳機20、隔音耳機或保暖耳罩等。Step 6: Please refer to FIG. 1 and FIG. 2, after filling the accommodating space 111 of the pouch 11 with soft fillers such as the sponge 12, foam, etc., then connect the opening portion 112 of the pouch 11 Attaching the viscous substance 13, the earmuff 10 is formed, that is, the plastic sheet 14 connected thereto is fixed to an object that can cover the ear, and the object that can cover the ear includes: the earmuff-type earphone 20. Soundproof earphones or warm earmuffs, etc.

請參閱第7、8圖所示，本實施例中使用真空成型技術，因該成形凹槽35之環形氣室37為環形結構，抽走空氣時，透過環形結構，令其吸力力道均勻，使該皮料60均勻貼附在該成形凹槽35內延展塑形，當冷卻時，因該囊袋11是被固定在該成形模具30內，尤其該連接部112之範圍係受該成形模具30所束縛，且該囊袋11因受限於該成形凹槽35內，故周圍沒有多餘的皮料可以令其收縮，因此收縮範圍有限，以至於該囊袋11之尺寸精準度較習知高，進而可降低與該塑片14結合時的誤差；且本發明利用下凹式之成形模具30，該環形氣室37抽氣處為該囊袋11凸起的部分，非該連接部112，因此，當抽氣停止時，即使該囊袋11有收縮，也不會影響到該連接部112之尺寸(請參閱第1圖所示)。Please refer to Figures 7 and 8, the vacuum forming technology is used in this embodiment, because the annular air chamber 37 of the forming groove 35 is an annular structure, when the air is evacuated, through the annular structure, the suction force is uniform, so that The leather 60 is evenly attached to the forming groove 35 to extend and shape. When cooling, the bladder 11 is fixed in the forming mold 30, especially the range of the connecting portion 112 is affected by the forming mold 30 Is constrained, and the pocket 11 is restricted by the forming groove 35, so there is no excess leather around to shrink it, so the shrinkage range is limited, so that the size accuracy of the pocket 11 is higher than that of the conventional ones , And can further reduce the error when combining with the plastic sheet 14; and the present invention uses a concave forming mold 30, the suction portion of the annular air chamber 37 is the convex portion of the pouch 11, not the connecting portion 112, Therefore, when the pumping stops, even if the bladder 11 contracts, it will not affect the size of the connecting portion 112 (see FIG. 1).

請再參閱第7圖所示，其中該成形模具30進行真空成形時，空氣從該成形模具30之底部，即該本體31與該底座32接合處，由下往上開始抽氣，接著到操作面，即該環形氣室37，空氣在該環形氣室37中環狀流動，達到環狀吸力、抽氣力道均勻，令該囊袋11均勻成形。Please refer to FIG. 7 again, wherein when the forming mold 30 is vacuum formed, air is drawn from the bottom of the forming mold 30, that is, the junction of the body 31 and the base 32, from bottom to top, and then to the operation The surface, that is, the annular air chamber 37, the air flows in the annular air chamber 37 in an annular shape to achieve an annular suction force and uniform suction force, so that the bladder 11 is uniformly formed.

請再參閱第7、8圖所示，本實施例在成形時，該皮料60受真空抽氣影響，會與該成形模具30之成形凹槽35緊密結合，因此，該成形模具30上若有任何紋路，皆會印在該囊袋11上，令該囊袋11上具有不同紋路，緣此之故，在製造該成形模具30時，可依照客戶需要，在該成形模具30上刻上Logo或文字，客制化該囊袋11。Please refer to FIG. 7 and FIG. 8 again, during the forming of this embodiment, the leather 60 is affected by the vacuum and will be closely combined with the forming groove 35 of the forming mold 30. Therefore, if the forming mold 30 has Any pattern will be printed on the pouch 11 so that the pouch 11 has different patterns. For this reason, when manufacturing the forming mold 30, the forming mold 30 can be engraved according to customer needs Logo or text to customize the bag 11.

請參閱第8圖所示，利用本發明所產生囊袋11之與習知技術相比，該囊袋11為柔軟、不成形的平面結構，平面結構之伸縮性相較立體幅度小，因此大幅降低該囊袋11整體收縮範圍，提高該囊袋11之準確性。As shown in FIG. 8, compared with the conventional technology, the bladder 11 produced by the present invention has a soft, non-formed planar structure, and the planar structure has a smaller stretch than the three-dimensional range, so it is significantly The overall contraction range of the pouch 11 is reduced, and the accuracy of the pouch 11 is improved.

惟以上所述者，僅為本發明之較佳實施例而已，當不能以此限定本發明實施之範圍；故，凡依本發明申請專利範圍及發明說明書內容所作之簡單的等效變化與修飾，皆應仍屬本發明專利涵蓋之範圍內。However, the above are only preferred embodiments of the present invention, which should not be used to limit the scope of implementation of the present invention; therefore, simple equivalent changes and modifications made according to the scope of the patent application of the present invention and the content of the invention description , Should still fall within the scope of this invention patent.
