Description
本發明屬加熱熱場裝置技術領域，特別係針對立體模造玻璃連續成型裝置之下加熱熱場裝置結構嶄新設計，本發明底座能將加熱塊熱場的熱有效阻絕，除具有確保立體模造玻璃產品尺寸的精準度外，並能將加熱塊熱場的熱有效阻絕，大幅降低冷卻裝置帶走之熱損失，更具有大幅降低生產成本之功效。 The invention belongs to the technical field of heating and heating field devices, in particular to the new design of the heating and heating field device under the three-dimensional mold glass continuous forming device, and the base of the invention can effectively block the heat of the heating block heat field, in addition to ensuring the three-dimensional molded glass product. In addition to the accuracy of the size, the heat of the heating block heat field can be effectively blocked, the heat loss taken by the cooling device is greatly reduced, and the production cost is greatly reduced.
按，玻璃因為具有較高透光的特性，因此顯示裝置(如手機、手錶等電子產品)多選其作為視窗部份的外殼。君可見手持電子產品表面通常設有玻璃殼體，以保護產品內部的顯示模組。目前玻璃殼體大部分都是平板的外形，所以在電子產品的上表面會形成有接縫。再者，由於電子產品的周邊必須保留一定寬度的機構部分，用以固持平板狀的玻璃，因此電子產品的頂面也就無法完全被利用。因此，立體或曲面玻璃已漸漸的被運用於電子產品的玻璃殼體上。 According to the glass, because of its high light transmission characteristics, display devices (such as mobile phones, watches and other electronic products) are often selected as the outer casing of the window portion. It can be seen that the surface of the handheld electronic product is usually provided with a glass casing to protect the display module inside the product. At present, most of the glass casings are in the shape of a flat plate, so seams are formed on the upper surface of the electronic product. Furthermore, since the peripheral portion of the electronic product must retain a certain width of the mechanism portion for holding the flat glass, the top surface of the electronic product cannot be fully utilized. Therefore, three-dimensional or curved glass has gradually been applied to the glass casing of electronic products.
平板式玻璃殼體較易製造，而具有立體形狀的玻璃殼體製造則較為不易。目前，具有立體形狀的玻璃殼體的製造通常有兩種方法：第一種為：製造多片平板式玻璃單元，然後藉由黏貼邊緣的方式形成具有立體形狀的玻璃殼體。第二種為：製造一定厚度的長方體玻璃，而後於該長方體玻璃上多次的研磨以形成具有多側面的立體造型。然而，上述二方法 均耗時耗力，生產速度非常慢。一般而言，由於玻璃素材係為一平板狀，如果要生產一具有造型之玻璃，較佳的作法係將平板狀的玻璃素材設置於一上模件與一下模件之間，接著加熱上模件、下模件以及玻璃素材，以使玻璃素材軟化。當上述之玻璃素材軟化時，上模件與下模件便可進行合模動作，以使上模件沿一合模方向與下模件共同塑造玻璃素材的外形，藉以生產相對應之模造玻璃。我國專利公告M452174號「用來製造模造玻璃之成型設備」(公告日2013年05月01日專利公告資料參照)，其包含有一母型模具件、一第一公型模具件、一第二公型模具件、一支撐頂桿以及一壓桿。該第一公型模具件以可開合之方式設置於該母型模具件上，該第二公型模具件設置於該母型模具件與該第一公型模具件之間。該支撐頂桿穿設於該母型模具件，該支撐頂桿用來推頂於該第二公型模具件，藉以支撐該第二公型模具件與該第一公型模具件共同夾持一模造玻璃。該壓桿設置於該第一公型模具件之一側，該壓桿用來下壓於該第一公型模具件，以使該第一公型模具件與該第二公型模具件相對該母型模具件移動至一合模位置，藉以成型該模造玻璃。 A flat glass housing is easier to manufacture, and a glass housing having a three-dimensional shape is relatively difficult to manufacture. At present, there are generally two methods for manufacturing a glass shell having a three-dimensional shape: the first one is to manufacture a plurality of flat glass units, and then form a glass shell having a three-dimensional shape by adhering the edges. The second type is: manufacturing a rectangular parallelepiped glass of a certain thickness, and then grinding it on the rectangular parallelepiped glass several times to form a three-dimensional shape having a plurality of sides. However, the above two methods Both are time consuming and labor intensive, and the production speed is very slow. In general, since the glass material is a flat plate, if a glass having a shape is to be produced, it is preferable to arrange a flat glass material between an upper mold and a lower mold, and then heat the upper mold. Pieces, lower molds and glass materials to soften the glass material. When the glass material is softened, the upper mold member and the lower mold member can be clamped, so that the upper mold member and the lower mold member together shape the shape of the glass material along a mold clamping direction, thereby producing a corresponding molded glass. . China Patent Publication No. M452174 "Molding Equipment for Molding Glass" (refer to the patent publication date of the announcement date of May 1, 2013), which comprises a female mold part, a first male mold part, and a second public A mold part, a support ram and a pressure bar. The first male mold member is disposed on the female mold member in an openable manner, and the second male mold member is disposed between the female mold member and the first male mold member. The support ejector is disposed on the female mold member, and the support ejector rod is used for pushing the second male mold member to support the second male mold member and the first male mold member A molded glass. The pressing rod is disposed on one side of the first male mold part, and the pressing rod is used for pressing down the first male mold part such that the first male mold part is opposite to the second male mold part The master mold member is moved to a clamping position to form the molded glass.
利用熱壓成型技術製作3D立體模造玻璃之成型機，有利用加熱裝置直接對模具加熱者，如申請人先前提出獲准之M524845號「模造立體玻璃連續成型裝置之加熱裝置」【105年7月1日公告】，其係特別針對立體模造玻璃連續成型裝置之加熱裝置結構嶄新設計，該加熱裝置係由熱傳導佳材質一體成型之加熱塊構成，該加熱塊並具有適當數量的槽孔以設置加熱元件，由於加熱塊係一體成型構成，沒有傳導的熱損失，熱傳導佳，適用於較高溫立體模造玻璃之連續成型。惟，由於該前案加熱元件係設置於 加熱塊的槽孔內，使用一段時間後，若加熱元件有損壞，一般僅更換損壞的加熱元件，如此當造成新更換的加熱元件與與使用一段時間的加熱元件一併使用的情形，由於新舊加熱元件加熱的溫度會有差異，如此當造成加熱塊受熱溫度不均勻，使模造立體玻璃產品良率一直降低，為其缺失。再者，由於加熱元件為了易於設置於加熱塊的槽孔內，加熱元件的外緣與槽孔的結合內緣必定存在有間隙，此間隙當具有熱傳導損失的缺失。據此，申請復提出I606017號「模造立體玻璃連續成型裝置之加熱裝置」【106年11月21日公告】，主要係由熱傳導佳材質一體成型之加熱塊及底座所構成，該加熱塊具有適當數量的槽孔以緊密結合加熱元件，且加熱元件與加熱塊槽孔間無間隙，加熱塊係以可拆式元件固定於底座上，底座則以可拆式元件固定於模造立體玻璃連續成型裝置預定位置上，在更換加熱元件時係更換含加熱元件之加熱塊，不更換底座，使連同結合於加熱塊上所有的加熱元件一併更換，也確能摒除前揭缺失。 A 3D three-dimensional molded glass forming machine is produced by a hot press forming technique, and a heating device directly heats the mold. For example, the applicant has previously proposed the approved M524845 "heating device for molding a stereoscopic glass continuous forming device" [July 1, 1 May] Japanese Announcement, which is specially designed for the structure of the heating device of the three-dimensional mold glass continuous forming device, which is composed of a heat block integrally formed by a heat conduction material, and the heating block has an appropriate number of slots to set the heating element. Since the heating block is integrally formed, there is no heat loss of conduction, and heat conduction is good, and is suitable for continuous molding of high-temperature stereo-molding glass. However, since the heating element of the previous case is set In the slot of the heating block, if the heating element is damaged after a period of use, generally only the damaged heating element is replaced, so that when the newly replaced heating element is used together with the heating element used for a period of time, due to the new The heating temperature of the old heating element will be different, so that when the heating block is heated unevenly, the yield of the molded stereoscopic glass product is always reduced, and it is missing. Furthermore, since the heating element is easily disposed in the slot of the heating block, there must be a gap between the outer edge of the heating element and the inner edge of the slot, and the gap has a loss of heat conduction loss. Accordingly, the application for the re-provision of I606017 "The heating device for the molded three-dimensional glass continuous forming device" [November 21, 2011] is mainly composed of a heating block and a base integrally formed by a heat conduction material, and the heating block has appropriate The number of slots is tightly coupled to the heating element, and there is no gap between the heating element and the heating block slot. The heating block is fixed to the base by a detachable component, and the base is fixed to the molded stereoscopic glass continuous forming device by a detachable component. In the predetermined position, when the heating element is replaced, the heating block containing the heating element is replaced, and the base is not replaced, so that all the heating elements combined with the heating block are replaced together, and the missing portion can be eliminated.
惟，前揭專利由於加熱塊係由熱傳導佳金屬材質一體成型構成，加熱塊係以可拆式元件固定於底座上，由於一般金屬之熱傳導仍不夠快，使得加熱塊與加熱元件所構成之熱場之熱傳導及均溫性能仍有改善空間。 However, in the prior patent, since the heating block is integrally formed of a heat-conducting metal material, the heating block is fixed to the base by a detachable component, and since the heat conduction of the metal is still not fast enough, the heat of the heating block and the heating element is formed. There is still room for improvement in heat transfer and temperature uniformity of the field.
再者，請參閱第1圖所示，由於下加熱裝置(A)，其加熱塊(B)及底座(C)均係由熱傳導佳金屬材質一體成型構成，加熱塊(B)具有適當數量的槽孔(F)以緊密結合加熱元件(G)而構成加熱熱場，加熱塊(B)加熱熱場的熱係直接傳導給金屬底座(C)，除將造成底座(C)因高溫而致有變形之虞，且承壓性不足，無法確保立體模造玻璃產品尺寸的精準度缺失外。如前所述 習用金屬底座(C)係以可拆式元件固定於模造立體玻璃連續成型裝置預定位置上，即第1圖所示之金屬腔體(D)，金屬腔體(D)內設有冷卻水道(E)，金屬底座(C)將加熱熱場的熱傳導至金屬腔體(D)，為避免金屬腔體(D)變形，將藉由冷卻水道(E)內冷卻水將源源不斷傳導到金屬腔體(D)的熱帶走，如此將造成極大的能源損耗，徒增加生產成本。本發明針對此缺失，提出更佳之設計，使模造立體玻璃連續成型裝置之下加熱熱場裝置專利更臻完善。 Furthermore, as shown in Fig. 1, since the lower heating device (A), the heating block (B) and the base (C) are integrally formed of a heat conductive metal material, and the heating block (B) has an appropriate number. The slot (F) constitutes a heating heat field by closely bonding the heating element (G), and the heat system of the heating block (B) heating the heat field is directly transmitted to the metal base (C), which causes the base (C) to be caused by high temperature. There is a deformation, and the pressure is insufficient, and it is impossible to ensure the accuracy of the dimensional dimension of the three-dimensional molded glass product. As mentioned earlier The conventional metal base (C) is fixed at a predetermined position of the molded stereoscopic glass continuous forming device by a detachable component, that is, the metal cavity (D) shown in FIG. 1 , and the cooling water channel is provided in the metal cavity (D) ( E), the metal base (C) conducts the heat of the heated heat field to the metal cavity (D), and in order to avoid deformation of the metal cavity (D), the source is continuously conducted to the metal cavity by the cooling water in the cooling water channel (E) The tropical movement of the body (D) will cause great energy loss and increase production costs. In view of this deficiency, the present invention proposes a better design, and the patent for heating the thermal field device under the molded stereoscopic glass continuous forming device is more perfect.
