Description
本案係關於一種閥門結構，特別是一種用於真空系統之純機械式之閥門結構。This case relates to a valve structure, in particular to a purely mechanical valve structure for a vacuum system.
於傳統壓鑄製程中，通常係將液體灌入於一成形模具中，待液體凝固後，即製成一鑄件產品。然而，依此製程卻難以避免會發生殘留氣體於該鑄件之問題，因而形成氣孔、浮泡等缺陷。這樣一來，不但會影響生產線之良率，更使該鑄件產品無法再進行熱處理，進而限制了該鑄件產品的機械強度，以及減縮該鑄件產品的應用範圍。In the conventional die-casting process, liquid is usually poured into a forming mold, and after the liquid is solidified, a casting product is produced. However, according to this process, it is difficult to avoid the problem that residual gas may be generated in the casting, thereby forming defects such as pores and buoys. In this way, not only will the yield of the production line be affected, but the casting product can no longer be heat treated, thereby limiting the mechanical strength of the casting product and reducing the application range of the casting product.
於是，目前業者藉由使用「真空壓鑄法」以有效解決氣孔缺陷的壓鑄製程。如台灣專利案521669號所揭露之壓鑄機之真空閥結構改良，即是利用此原理來達成產品品質的提升。不過與傳統壓鑄製程相較之下，就相對存在著設備成本高與保養維護不易等問題。其中，真空閥係為掌控真空壓鑄系統中真空效果的關鍵零組件，更是影響整個真空壓鑄系統的成本。再者，目前市售的真空閥多需搭配迂迴流道與電子感應控制系統，因此更使得成形時間拉長。綜上所述，目前使用真空壓鑄法製造之廠商，有著製造成本高、產能下降、設備操作以及維護成本提高的結果。Therefore, the current manufacturer uses the "vacuum die casting method" to effectively solve the hole casting process of the hole defect. For example, the improvement of the vacuum valve structure of the die casting machine disclosed in Taiwan Patent No. 521669 is to use this principle to achieve an improvement in product quality. However, compared with the traditional die-casting process, there are relatively high problems such as high equipment cost and difficult maintenance. Among them, the vacuum valve is the key component to control the vacuum effect in the vacuum die-casting system, and it also affects the cost of the entire vacuum die-casting system. Moreover, the currently available vacuum valves are often required to be combined with a helium return channel and an electronic induction control system, thereby further prolonging the forming time. In summary, manufacturers currently using vacuum die casting have the consequences of high manufacturing costs, reduced capacity, improved equipment operation and maintenance costs.
有鑑於此，若能提供一種閥門結構，以純機械結構搭配簡單的流道系統，除毋需進行額外的操作與計算外，並可同時降低真空閥的製造成本、不影響產能，更能減省保養次數及真空壓鑄系統整體成本，此乃為業界亟待解決的問題。In view of this, if a valve structure can be provided, a pure mechanical structure with a simple flow channel system can eliminate the need for additional operations and calculations, and at the same time reduce the manufacturing cost of the vacuum valve without affecting the production capacity. The number of maintenance and the overall cost of the vacuum die-casting system is an urgent problem for the industry.

The passage 115 extracts the air remaining in the liquid passage 113, thereby avoiding the occurrence of holes and defects due to residual air in the liquid passage 113 when the liquid is hardened to form the casting, thereby improving the quality of the casting after the liquid hardening is formed. .
於本案之第一實施例中，活動件13具有基部130、自基部130之相對兩表面分別突出形成之第一配合部132以及瓣膜部134。其中，第一配合部132、基部130以及瓣膜部134較佳為一體成形，不但使活動件13於製作上方便，更能整體提高活動件13之強度，而增加耐用性；但亦可視情況而採元件組裝方式，並不以此為限。In the first embodiment of the present invention, the movable member 13 has a base portion 130, a first engaging portion 132 and a valve portion 134 which are respectively protruded from opposite surfaces of the base portion 130. The first engaging portion 132, the base portion 130, and the valve portion 134 are preferably integrally formed, which not only makes the movable member 13 convenient to manufacture, but also improves the strength of the movable member 13 as a whole, thereby increasing durability; The assembly method of components is not limited to this.
再者，閥體11係由可相互組合之一前閥板111以及一後閥板112所組合而成，且活動件13被前閥板111以及後閥板112前後夾設，以使活動件13得輕易地被裝設於閥體11內。於本實施例中，前閥板111具有一容置空間110，而活動件13之第一配合部132適可容置於容置空間110；前閥板111以及後閥板112相接處形成有一凹槽119，凹槽119係空間連通於容置空間110，而基部130適以容置於凹槽119；後閥板112具有液體通道113以及抽氣通道115，活動件13之瓣膜部134適可容置於液體通道113。當然，前閥板111以及後閥板112之設置僅為方便說明之結構例舉，熟知本技術領域者可輕易變化其設計以及外觀，故並不以此為限。Furthermore, the valve body 11 is formed by combining a front valve plate 111 and a rear valve plate 112, and the movable member 13 is sandwiched by the front valve plate 111 and the rear valve plate 112 to move the movable member. 13 is easily installed in the valve body 11. In the present embodiment, the front valve plate 111 has an accommodating space 110, and the first engaging portion 132 of the movable member 13 is adapted to be received in the accommodating space 110; the front valve plate 111 and the rear valve plate 112 are joined to each other. There is a groove 119, the groove 119 is spatially connected to the accommodating space 110, and the base 130 is adapted to be received in the groove 119; the rear valve plate 112 has a liquid passage 113 and an air suction passage 115, and the valve portion 134 of the movable member 13 Suitably placed in the liquid channel 113. Of course, the arrangement of the front valve plate 111 and the rear valve plate 112 is merely for convenience of description. It is well known in the art that the design and appearance of the valve plate 111 can be easily changed.
請進一步合併參閱圖1至圖3，瓣膜部134具有一被推動端134a，當被推動端134a面對於液體通道113之注入口116設置時，瓣膜部134係處於該初始位置；此時抽氣通道115係氣體連過於液體通道113，故可利用抽氣通道115將液體通道113內之氣體抽出，使液體道通內之氣體降於一大氣壓之下，甚至達到接近真空狀態。當操作者欲利用具有本案之閥門結構1之該一系統執行鑄模而灌入液體時，液體適可迅速流入液體通道113，故被推動端134a適可接受液體之衝擊，而使瓣膜部134被帶動且沿第一旋轉方向D1旋轉至該封阻位置(如圖4以及圖5所示)，而封阻了液體通道113與抽氣通道115之間之氣體連通。藉此以避免液體灌至抽氣通道115，而保護抽氣通道115之抽氣功能不受損害。Referring further to FIG. 1 to FIG. 3, the valve portion 134 has a pushed end 134a. When the pushed end 134a is disposed on the injection port 116 of the liquid passage 113, the valve portion 134 is in the initial position; The passage 115 is connected to the gas passage 113, so that the gas in the liquid passage 113 can be extracted by the suction passage 115, and the gas in the liquid passage can be lowered to a pressure below atmospheric pressure, even reaching a vacuum state. When the operator wants to use the system having the valve structure 1 of the present invention to perform the casting and pouring the liquid, the liquid can quickly flow into the liquid passage 113, so that the pushed end 134a can receive the impact of the liquid, and the valve portion 134 is It is driven and rotated in the first rotational direction D1 to the blocking position (as shown in FIGS. 4 and 5), and the gas communication between the liquid passage 113 and the suction passage 115 is blocked. Thereby, liquid is prevented from being poured into the suction passage 115, and the suction function of the suction passage 115 is protected from damage.
接下來詳細敘述活動件13之復位方式。請合併參閱圖1、圖4以及圖5，鄰設於閥體11旁之復位機構15具有一第二配合部152，第二配合部152具有與活動件13之第一配合部132相對應之形狀；故當復位機構15接受朝向閥體11之軸向頂推力時，復位機構15適可朝第一配合部132進行一非轉動式之軸向移動(non-rotating displacement)，以使第二配合部152進入容置空間110以頂推第一配合部132，而第一配合部132適可因應第二配合部152，進行一非軸向移動式之轉動(non-displacing rotation)。俾使瓣膜部134自該封阻位置沿第二旋轉方向D2旋轉回位至該初始位置。於此需說明者為，第一配合部132以及第二配合部152係各自可以為相互配合之一斜面、一雙曲線斜面180(如圖6所示)、一雙曲面181(如圖7所示)以及一螺紋斜面182(如圖8所示)等可相互作動之規則曲面或不規則曲面，但並不以此為限。Next, the reset mode of the movable member 13 will be described in detail. Referring to FIG. 1 , FIG. 4 and FIG. 5 , the reset mechanism 15 disposed adjacent to the valve body 11 has a second mating portion 152 , and the second mating portion 152 has a corresponding portion 132 of the movable member 13 . Shape; therefore, when the reset mechanism 15 receives the axial thrust toward the valve body 11, the reset mechanism 15 is adapted to perform a non-rotating displacement toward the first mating portion 132 to make the second The mating portion 152 enters the accommodating space 110 to push the first mating portion 132, and the first mating portion 132 is adapted to perform a non-displacing rotation in response to the second mating portion 152. The valve portion 134 is rotated back from the blocking position in the second rotational direction D2 to the initial position. It should be noted that the first engaging portion 132 and the second engaging portion 152 may each be a matching inclined surface, a hyperbolic inclined surface 180 (as shown in FIG. 6 ), and a hyperboloid 181 (as shown in FIG. 7 ). And a threaded slope 182 (shown in FIG. 8), such as a regular curved surface or an irregular curved surface, but not limited thereto.
為進一步限定復位裝置能於沿該軸向上位移，復位機構15具有複數定位插銷154，而閥體11具有複數插孔(圖未示)，復位機構15之定位插銷154相對應插設於閥體11之該等插孔中，使復位機構15能更穩定地與閥體11相互作動。其中，復位機構15與閥蓋17可沿該軸向作同步之位移，且復位機構15可連接有一頂出裝置(圖未示)。藉此設置，當復位機構15朝閥體11接近時，閥蓋17遠離閥體11而顯露凝固之液體，並可藉由該頂出裝置將已凝固之液體頂出，以獲取一鑄件。To further define that the reset device can be displaced along the axial direction, the reset mechanism 15 has a plurality of positioning pins 154, and the valve body 11 has a plurality of sockets (not shown), and the positioning pins 154 of the reset mechanism 15 are correspondingly inserted into the valve body. Among the jacks of 11, the reset mechanism 15 can be more stably operated with the valve body 11. Wherein, the reset mechanism 15 and the valve cover 17 can be synchronously displaced along the axial direction, and the reset mechanism 15 can be connected with an ejection device (not shown). With this arrangement, when the reset mechanism 15 approaches the valve body 11, the valve cover 17 is away from the valve body 11 to reveal the solidified liquid, and the solidified liquid can be ejected by the ejector to obtain a casting.
相似地，當復位裝置以及閥蓋17回位的同時，復位機構15遠離閥體11，閥蓋17朝閥體11接近蓋合，以密閉液體通道113。再者，基部130沿徑向方向之一長度不小於瓣膜部134之長度，且基部130較佳為呈一圓盤形，如此一來，便可解決液體凝固後之熔渣可能卡在活動件13和閥體11之間的問題。Similarly, while the resetting device and the valve cover 17 are returned, the reset mechanism 15 is away from the valve body 11, and the valve cover 17 is brought close to the valve body 11 to close the liquid passage 113. Furthermore, the length of the base portion 130 in the radial direction is not less than the length of the valve portion 134, and the base portion 130 preferably has a disc shape, so that the slag after liquid solidification may be stuck in the movable member. The problem between 13 and the valve body 11.
圖9係為本案之閥門結構之第二實施例之立體***圖，圖10係為本案之閥門結構之第二實施例之立體示意圖，並請參閱圖9以及圖10。於第二實施例中，閥門結構2仍係利用復位機構25之第二配合部252來頂推活動件23之第一配合部232，其異於第一實施例者為，活動件23具有第一配合部232以及一瓣膜部234，而未具有如第一實施例中之基部130而可相應減省前閥板111上凹槽119之設置。至於本案之閥門結構之第二實施例之瓣膜部234與復位機構25間之相互作動關係；以及其可能的實施方式，皆如同於第一實施例，故於此不再贅述。此外，瓣膜部之外觀亦可改變成為一長方體之瓣膜部234’(如圖11所示)。當然，閥體亦須隨瓣膜部234’之形狀作相對應之外形改變，而上述結構形狀僅為一列舉，於此並不對其作一限制。9 is a perspective exploded view of a second embodiment of the valve structure of the present invention, and FIG. 10 is a perspective view of a second embodiment of the valve structure of the present invention, and FIG. 9 and FIG. In the second embodiment, the valve structure 2 still pushes the first engaging portion 232 of the movable member 23 by the second engaging portion 252 of the reset mechanism 25, which is different from the first embodiment in that the movable member 23 has the first A mating portion 232 and a valve portion 234, without the base portion 130 as in the first embodiment, can correspondingly reduce the arrangement of the recess 119 on the front valve plate 111. As for the interaction between the valve portion 234 and the reset mechanism 25 of the second embodiment of the valve structure of the present invention; and the possible embodiments thereof, as in the first embodiment, the details are not described herein. In addition, the appearance of the valve portion can also be changed into a cuboid valve portion 234' (as shown in Fig. 11). Of course, the valve body also has to change with the shape of the valve portion 234', and the above-mentioned structural shape is only an enumeration, and is not limited thereto.
圖12係為本案之閥門結構之第三實施例之立體***圖，圖13係為本案之閥門結構之第三實施例之立體示意圖，並請參閱圖12以及圖13。於本案之第三實施例中，閥門結構3已並非如同前二實施例中利用相對應之兩配合部以執行復位之動作(故本實施例中之活動件33已無配合部之設置，但仍留有一基部332以及一瓣膜部334)，而是利用各種形式的復位機構35分別與閥體31以及活動件33連接，以協助瓣膜部334復位。12 is a perspective exploded view of a third embodiment of the valve structure of the present invention, and FIG. 13 is a perspective view of a third embodiment of the valve structure of the present invention, and FIG. 12 and FIG. In the third embodiment of the present invention, the valve structure 3 is not the same as the two mating portions in the first two embodiments to perform the resetting action (the movable member 33 in this embodiment has no matching portion, but A base portion 332 and a valve portion 334 are still left, but are connected to the valve body 31 and the movable member 33 by various types of reset mechanisms 35, respectively, to assist in resetting the valve portion 334.
其中，復位機構35可以係為一線彈簧，線彈簧之兩端分別連接於閥體31以及活動件33，當液體凝固且被移除後，活動件33適可藉由線彈簧自該封阻位置回位至該初始位置。抑或，復位機構35係為一多連桿，多連桿之分別連接於閥體31以及活動件33，當液體凝固且被移除後，活動件33適可藉由多連桿自該封阻位置回位至該初始位置。抑或，復位機構35係為一皮帶輪，皮帶輪之分別套接於閥體31以及活動件33，當液體凝固且被移除後，活動件33適可藉由皮帶輪自該封阻位置回位至該初始位置。抑或，復位機構35係為兩齒輪，兩齒輪之分別設置於閥體31以及活動件33，且兩齒輪相互囓合，當液體凝固且被移除後，活動件33適可藉由兩齒輪自該封阻位置回位至該初始位置。故於本實施例中之活動件33具有一基部330以及一瓣膜部334而無配合部之設置，至於第三實施中之其它元件，因如同於第一實施例，故於此不再贅述。The reset mechanism 35 can be a linear spring. The two ends of the wire spring are respectively connected to the valve body 31 and the movable member 33. When the liquid is solidified and removed, the movable member 33 can be adapted from the blocked position by the wire spring. Return to the initial position. Or, the reset mechanism 35 is a multi-link, and the multi-links are respectively connected to the valve body 31 and the movable member 33. When the liquid is solidified and removed, the movable member 33 is adapted to be blocked by the multi-link. The position is returned to the initial position. Or, the reset mechanism 35 is a pulley, and the pulleys are respectively sleeved on the valve body 31 and the movable member 33. When the liquid is solidified and removed, the movable member 33 is adapted to be returned from the blocked position by the pulley to the initial position. Or, the reset mechanism 35 is two gears, the two gears are respectively disposed on the valve body 31 and the movable member 33, and the two gears mesh with each other. When the liquid is solidified and removed, the movable member 33 is adapted to be driven by the two gears. The blocked position is returned to the initial position. Therefore, the movable member 33 in the embodiment has a base portion 330 and a valve portion 334 without a fitting portion. As for the other components in the third embodiment, as will be described in the first embodiment, the details are not described herein.
圖14係為本案之閥門結構之第四實施例之瓣膜部處於一初始位置之正面示意圖，圖15係為本案之閥門結構之第四實施例之瓣膜部處於一封阻位置之正面示意圖，並請參閱圖1114以及圖15。本實施例異於前三個實施例者為，第四實施例之瓣膜部係為可執行線性滑動之瓣膜部，來取代前三個實施例中可執行轉動之瓣膜部，但仍能達到封阻抽氣通道415之效果。再者，第四實施例中之閥門結構4可選擇利用第一實施例以及第二實施例中所揭露之相配合之第一配合部132、232以及第二配合部152、252，以使瓣膜部134、234執行復位之動作；抑或利用第三實施例中之各種形式的復位機構35使瓣膜部334執行復位之動作。由於前三個實施例中針對復位機構已作詳細說明，故於此不再贅述。Figure 14 is a front elevational view showing the valve portion of the valve structure of the fourth embodiment of the present invention in an initial position, and Figure 15 is a front elevational view showing the valve portion of the fourth embodiment of the valve structure of the present invention in a resisting position, and Please refer to FIG. 1114 and FIG. 15. The embodiment is different from the first three embodiments. The valve portion of the fourth embodiment is a valve portion that can perform linear sliding instead of the valve portion that can be rotated in the first three embodiments, but can still be sealed. The effect of the resistance pumping passage 415. Furthermore, the valve structure 4 in the fourth embodiment can select the first mating portions 132, 232 and the second mating portions 152, 252 which are combined with the first embodiment and the second embodiment to make the valve The portions 134, 234 perform a resetting action; or the various types of the reset mechanism 35 in the third embodiment are used to cause the valve portion 334 to perform a resetting action. Since the reset mechanism has been described in detail in the first three embodiments, it will not be described herein.
於第四實施例中，閥門結構4之液體通道413包括一主支道413a以及兩副支道413b，多闢支道的原因在於，額外增闢之支道亦可用以容置液體，當然，若僅設置有一主支道413a，亦能良好運作。進一步而言，活動件43可移動地設置於主支道413a上，且係設置於面對於液體通道413之一注入口416之位置，藉此設置，俾使活動件43可因應液體之衝擊而被推動至該封阻位置。In the fourth embodiment, the liquid passage 413 of the valve structure 4 includes a main branch 413a and two auxiliary branches 413b. The reason for the additional branch is that the additional branch can also be used for accommodating the liquid. If only one main branch 413a is provided, it can work well. Further, the movable member 43 is movably disposed on the main branch 413a, and is disposed at a position facing the injection port 416 of one of the liquid passages 413, thereby being disposed so that the movable member 43 can respond to the impact of the liquid. Pushed to the blocked position.
綜上所述，本案所揭露之閥門結構係為一係單純的機械結構搭配簡單的液體通道，並且藉由液體之慣性以衝擊活動件，以封阻抽氣通道；而真空閥門開啟或關閉之控制，則毋須再依賴貴重之電子儀器作偵測，藉此，將能大幅減省購買之成本。除此之外，簡單的液體流道相較於習知技術中必須搭配之迂迴流道使得成形時間拉長、設定繁瑣，更有著成形時間快，且亦無操作困難與保養維護不易的問題。In summary, the valve structure disclosed in the present case is a simple mechanical structure with a simple liquid passage, and the inertia of the liquid is used to impact the movable member to block the suction passage; and the vacuum valve is opened or closed. Control, no need to rely on valuable electronic equipment for detection, which will greatly reduce the cost of purchase. In addition, the simple liquid flow path is longer than the conventional return flow path, which makes the forming time longer, the setting is cumbersome, the forming time is fast, and there is no difficulty in operation and maintenance and maintenance.
惟以上所述僅為本發明之較佳實施例，非意欲侷限本發明的專利保護範圍，故舉凡運用本發明說明書及圖式內容所為的等效變化，均同理皆包括於本發明的權利保護範圍內，合予陳明。However, the above description is only the preferred embodiment of the present invention, and is not intended to limit the scope of the invention, and the equivalents of the present invention and the equivalents of the drawings are all included in the present invention.
