Abstract
Description
本發明是有關於一種射出成型模具，且特別是有關於一種具有壓力感測器的射出成型模具。The present invention relates to an injection molding die, and more particularly to an injection molding die having a pressure sensor.
塑膠成型產品從一般日常用品、電子電器產品以至工業產品等均可利用，是現今產業界不可或缺的工具。Plastic molding products can be used from general daily necessities, electronic and electrical products as well as industrial products, and are indispensable tools in today's industry.
圖1是習知一種模具結構的局部示意圖。請參考圖1，射出成型模具100包括一第一模座110、一第二模座120、一頂出裝置130以及一復位裝置140。復位裝置140包括一連桿142與一結合件144，其中結合件144固定於頂出裝置130上。連桿142的一端固定於第一模座110，而其另一端則可移動地耦接於結合件144。Figure 1 is a partial schematic view of a conventional mold structure. Referring to FIG. 1 , the injection molding die 100 includes a first die holder 110 , a second die holder 120 , an ejection device 130 , and a reset device 140 . The reset device 140 includes a link 142 and a coupling member 144, wherein the coupling member 144 is fixed to the ejector device 130. One end of the connecting rod 142 is fixed to the first die holder 110, and the other end thereof is movably coupled to the coupling member 144.
當第一模座110與第二模座120相互分離後，頂出裝置130便會相對於第二模座120朝向第一模座110的方向移動，以使成型物(未繪示)從第二模座120中退出。接著，頂出裝置130與第二模座120便會依序復位。亦即當第一模座110與第二模座120相互閉閡時，第一模座110會帶動連桿142朝向第二模座120的方向移動，以將連桿142的一端抵壓於結合件144，並藉此將頂出裝置130推回圖式中的起始位置，以作為進行下一次射出成型預備位置。然此種連桿式的復位裝置140，其製作精度有限，且在長時間的模座110、120開闔動作之下，連桿142與結合 件144容易產生磨損，屆時更易造成復位裝置140失效而導致射出成型模具100損壞的情形發生。When the first mold base 110 and the second mold base 120 are separated from each other, the ejector device 130 moves relative to the second mold base 120 toward the first mold base 110, so that the molded product (not shown) The second mold base 120 is withdrawn. Then, the ejector device 130 and the second die holder 120 are sequentially reset. That is, when the first mold base 110 and the second mold base 120 are closed to each other, the first mold base 110 moves the connecting rod 142 toward the second mold base 120 to press one end of the connecting rod 142 against the joint. The piece 144, and thereby pushes the ejector device 130 back to the starting position in the drawing as the next injection molding preparation position. However, the link type reset device 140 has a limited manufacturing precision, and the link 142 is combined with the long-term mold bases 110 and 120. The piece 144 is prone to wear, and it is more likely to cause the failure of the resetting device 140 to cause damage to the injection molding die 100.
習知另一解決方式便是在模具結構上裝設微動開關，以藉由模座之間的距離判定是否達到預定位置。惟在模具結構可允許的經濟條件下，此種微動開關的精度並不高，因此常由於模座尚未到達預定位置便進行判可的動作。另一方面，此種微動開關亦容易因模具結構需不斷地開闔而產生磨損。一旦採用較高精度的微動開關，則其成本卻又不符經濟效益。Another solution is to install a micro switch on the mold structure to determine whether the predetermined position is reached by the distance between the mold bases. However, under the economic conditions allowed by the mold structure, the accuracy of such a micro switch is not high, and therefore the action of the mold base is often performed because the mold base has not yet reached the predetermined position. On the other hand, such a micro switch is also prone to wear due to the continuous opening of the mold structure. Once a higher precision microswitch is used, its cost is not economical.
本發明提供一種射出成型模具，其藉由壓力感測器而監測模具結構中的構件是否正確地復位。The present invention provides an injection molding die that monitors whether a component in a mold structure is properly reset by a pressure sensor.
本發明的一實施例提出一種射出成型模具，包括一第一模座、一頂出裝置以及一第一壓力感測器。第一模座具有一固定板與一模仁座。頂出裝置可移動地組裝至第一模座。頂出裝置具有一頂出板，設置於固定板與模仁座之間。壓力感測器設置在第一模座與頂出板之間以感測壓力。An embodiment of the present invention provides an injection molding die including a first mold base, an ejection device, and a first pressure sensor. The first mold base has a fixing plate and a mold holder. The ejector device is movably assembled to the first mold base. The ejector device has an ejection plate disposed between the fixing plate and the mold holder. A pressure sensor is disposed between the first mold base and the ejector plate to sense pressure.
在本發明之一實施例中，上述之射出成型模具還包括一第二壓力感測器。頂出裝置還包括一滑塊，可移動地設置在模仁座內。第二壓力感測器設置在滑塊與模仁座之間。In an embodiment of the invention, the injection molding die further includes a second pressure sensor. The ejector device further includes a slider movably disposed within the mold holder. The second pressure sensor is disposed between the slider and the mold base.
在本發明之一實施例中，上述之第一壓力感測器與第二壓力感測器彼此電性連接。In an embodiment of the invention, the first pressure sensor and the second pressure sensor are electrically connected to each other.
在本發明之一實施例中，上述之射出成型模具還包括 一第二模座，組裝至第一模座。第一模座與第二模座彼此能相對地開闔。In an embodiment of the invention, the injection molding die described above further includes A second mold base is assembled to the first mold base. The first mold base and the second mold base can be relatively open to each other.
在本發明之一實施例中，上述之射出成型模具還包括一第三壓力感測器，設置在第一模座與第二模座之間。In an embodiment of the invention, the injection molding die further includes a third pressure sensor disposed between the first mold base and the second mold base.
在本發明之一實施例中，上述之第一壓力感測器與第三壓力感測器彼此電性連接。In an embodiment of the invention, the first pressure sensor and the third pressure sensor are electrically connected to each other.
在本發明之一實施例中，上述之第一壓力感測器包括一對導電片以及一絕緣件。絕緣件配置在此對導電片之間且具有一孔洞。當頂出板接觸第一模座時，頂出板與第一模組分別藉由此對導電片壓迫絕緣件，以使此對導電片經由孔洞互相接觸並導通。In an embodiment of the invention, the first pressure sensor comprises a pair of conductive sheets and an insulating member. The insulating member is disposed between the pair of conductive sheets and has a hole. When the ejector plate contacts the first mold base, the ejector plate and the first module respectively press the insulating member against the conductive sheet, so that the pair of conductive sheets contact and communicate with each other via the holes.
基於上述，在本發明的上述實施例中，由於壓力感測器配置在模座與頂出裝置之間，因此當射出成型模具完成成型品退出的動作之後，射出成型機能藉由壓力感測器所感測到的壓力而判斷模座與頂出裝置是否已經復位。藉此，在射出成型的製程中，一旦發生頂出裝置或模座未復位，使用者便能即時進行故障排除，以避免模具損壞。Based on the above, in the above embodiment of the present invention, since the pressure sensor is disposed between the die holder and the ejection device, the injection molding machine can be used by the pressure sensor after the injection molding die completes the action of the molded product exiting. The sensed pressure determines whether the mold base and the ejector have been reset. Thereby, in the process of injection molding, once the ejector device or the mold base is not reset, the user can immediately perform troubleshooting to avoid mold damage.
為讓本發明之上述特徵和優點能更明顯易懂，下文特舉實施例，並配合所附圖式作詳細說明如下。The above described features and advantages of the present invention will be more apparent from the following description.
圖2是依照本發明一實施例的一種射出成型模具的方塊圖。圖3是圖2中射出成型模具的示意圖。請同時參考圖2及圖3，射出成型模具200用以設置在一射出成型機 300。射出成型模具200包括一第二模座210、一第一模座220、一頂出裝置230以及一第一壓力感測器240。第二模座210組裝於第一模座220，且射出成型機300能驅動第一模座220與第二模座210彼此相對地開闔。頂出裝置230組裝至第一模座220，且射出成型機300能驅動頂出裝置230相對於第二模座210移動。第一壓力感測器240可拆卸地設置在頂出裝置230與第一模座220之間並電性連接至射出成型機300。2 is a block diagram of an injection molding die in accordance with an embodiment of the present invention. Figure 3 is a schematic view of the injection molding die of Figure 2. Referring to FIG. 2 and FIG. 3 simultaneously, the injection molding die 200 is disposed on an injection molding machine. 300. The injection molding die 200 includes a second die holder 210, a first die holder 220, an ejection device 230, and a first pressure sensor 240. The second mold base 210 is assembled to the first mold base 220, and the injection molding machine 300 can drive the first mold base 220 and the second mold base 210 to open opposite to each other. The ejector unit 230 is assembled to the first mold base 220, and the injection molding machine 300 can drive the ejector unit 230 to move relative to the second mold base 210. The first pressure sensor 240 is detachably disposed between the ejector device 230 and the first mold base 220 and electrically connected to the injection molding machine 300.
當射出成型機300藉由將塑料注入閉閡的第一模座220與第二模座210之間，並冷卻形成一塑膠件400後。射出成型機300便驅動第一模座220相對於第二模座210展開，接著並驅動頂出裝置230相對於第一模座220移動，以將塑膠件400退出射出成型模具200。此時，第一壓力感測器240會藉由感測第一模座220與頂出裝置230之間的壓力，而使射出成型機300監測第一模座220與頂出裝置230的位置，在確保頂出裝置230與第一模座220依序完成復位動作後，射出成型機300方進行下一模次的射出成型動作。一旦頂出裝置230與第一模座220的其中之一無法完成復位動作，則立即會在射出成型機300上產生警告訊號，藉以警告使用者需立即進行故障排除。The injection molding machine 300 is formed by injecting plastic between the closed first mold base 220 and the second mold base 210 and cooling to form a plastic member 400. The injection molding machine 300 drives the first die holder 220 to be unfolded relative to the second die holder 210, and then drives the ejector device 230 to move relative to the first die holder 220 to withdraw the plastic member 400 from the injection molding die 200. At this time, the first pressure sensor 240 causes the injection molding machine 300 to monitor the position of the first mold base 220 and the ejector unit 230 by sensing the pressure between the first mold base 220 and the ejector unit 230. After ensuring that the ejector unit 230 and the first die holder 220 sequentially complete the resetting operation, the injection molding machine 300 performs the next molding injection molding operation. Once the resetting action is not completed by one of the ejector unit 230 and the first mold base 220, a warning signal is immediately generated on the injection molding machine 300 to warn the user that the fault diagnosis is required immediately.
基於上述，在本實施例的射出成型模具200中，藉由設置第一壓力感測器240，而使射出成型機300得以監測射出成型模具200中相關構件的位置，以進一步確保射出成型製程的順利進行。此舉避免習知技術的模具結構100 中，頂出裝置130或其他相關構件未復位而造成彼此干涉並損壞的情形。在本實施例中，一旦相關構件未回復至預定位置，則射出成型機300可通知使用者進行故障排除，或是再驅動射出成型模具200的相關構件移動至預定位置，因而能確保於下一次的射出成型時，射出成型模具200的相關構件皆能回復至預設位置。Based on the above, in the injection molding die 200 of the present embodiment, by providing the first pressure sensor 240, the injection molding machine 300 can monitor the position of the relevant member in the injection molding die 200 to further ensure the injection molding process. Going smoothly. This avoids the prior art mold structure 100 In the case where the ejector device 130 or other related components are not reset, causing interference and damage to each other. In the present embodiment, once the relevant member has not returned to the predetermined position, the injection molding machine 300 can notify the user to perform troubleshooting or re-drive the relevant member of the injection molding die 200 to a predetermined position, thereby ensuring the next time. At the time of injection molding, the relevant members of the injection molding die 200 can be returned to the preset position.
詳細而言，在本實施例中，第一模座220包括一固定板222與一模仁座224，其中固定板222組裝在射出成型機300上，模仁座224組裝在固定板222上。頂出裝置230包括一頂出板232、一頂針234與一頂出銷236。頂出板232可移動地配置在固定板222與模仁座224之間，頂針234與頂出銷236的一端連接於頂出板232，而其另一端穿過模仁座224並抵靠在已冷卻成型的塑膠件400上。藉此，頂出板232便能帶動頂針234與頂出銷236將塑膠件400退出射出成型模具200。In detail, in the present embodiment, the first mold base 220 includes a fixing plate 222 and a mold base 224, wherein the fixing plate 222 is assembled on the injection molding machine 300, and the mold base 224 is assembled on the fixing plate 222. The ejector unit 230 includes an ejector plate 232, a thimble 234 and an ejector pin 236. The ejector plate 232 is movably disposed between the fixed plate 222 and the caliper seat 224. One end of the ejector pin 234 and the ejector pin 236 is coupled to the ejector plate 232, and the other end thereof passes through the caliper seat 224 and abuts against The molded plastic part 400 has been cooled. Thereby, the ejector plate 232 can drive the thimble 234 and the ejector pin 236 to withdraw the plastic member 400 from the injection molding die 200.
在本實施例中，第一壓力感測器240配置在固定板222與頂出板232之間，藉由感測頂出板232復位時施加於固定板222的壓力，而讓射出成型機300得以監測頂出板232是否已回復至射出成型前的初始位置。圖4是圖3的壓力感測器的剖面圖。請同時參考圖3及圖4，在本實施例中，第一壓力感測器240包括一對導電片242、244以及一絕緣件246，其中導電片242、244分別電性連接至射出成型機300。絕緣件246例如是一橡膠片，其配置在此對導電片242、244之間，且絕緣件246具有孔洞246a。In the present embodiment, the first pressure sensor 240 is disposed between the fixed plate 222 and the ejector plate 232, and the injection molding machine 300 is caused by sensing the pressure applied to the fixed plate 222 when the ejector plate 232 is reset. It is possible to monitor whether the ejector plate 232 has returned to the initial position before injection molding. 4 is a cross-sectional view of the pressure sensor of FIG. 3. Referring to FIG. 3 and FIG. 4 simultaneously, in the embodiment, the first pressure sensor 240 includes a pair of conductive sheets 242, 244 and an insulating member 246, wherein the conductive sheets 242, 244 are electrically connected to the injection molding machine, respectively. 300. The insulating member 246 is, for example, a rubber sheet disposed between the pair of conductive sheets 242, 244, and the insulating member 246 has a hole 246a.
據此，當頂出板232復位而接觸固定板222時，頂出板232與固定板222會分別抵壓導電片242、244，進而導電片242、244壓迫絕緣件246並使其變形，因此導電片242、244便會經由孔洞246a互相接觸而導通。當頂出板232與固定板222相互分離時，絕緣件246即藉由其彈性恢復力而使導電片242、244恢復初始未導通時的狀態。Accordingly, when the ejector plate 232 is reset and contacts the fixing plate 222, the ejector plate 232 and the fixing plate 222 respectively press the conductive sheets 242, 244, and the conductive sheets 242, 244 press the insulating member 246 and deform it. The conductive sheets 242, 244 are electrically connected to each other via the holes 246a. When the ejector plate 232 and the fixing plate 222 are separated from each other, the insulating member 246 returns the conductive sheets 242, 244 to a state where they are not initially turned on by their elastic restoring force.
在本實施例中，第一壓力感測器240的壓力大小取決於絕緣件246的厚度，因此使用者可依據射出成型模具200中不同構件所需的壓力值而選擇適當厚度的絕緣件246，以使射出成型模具200依照所需的正確位置進行運動。惟本實施例並未限制壓力感測器的形式，凡能感測射出成型模具200中任意相鄰構件之間的壓力，以監測這些構件是否復位者，皆可適用於本實施例。In the present embodiment, the magnitude of the pressure of the first pressure sensor 240 depends on the thickness of the insulating member 246, so the user can select the insulating member 246 of an appropriate thickness according to the pressure value required to inject different components in the molding die 200, The injection molding die 200 is moved in accordance with the desired correct position. However, the present embodiment does not limit the form of the pressure sensor, and any one that can sense the pressure between any adjacent members in the injection molding die 200 to monitor whether or not these members are reset can be applied to the present embodiment.
再者，本實施例亦未限定壓力感測器設置在第一模座220與頂出裝置230上的位置。Moreover, the embodiment does not limit the position where the pressure sensor is disposed on the first die holder 220 and the ejection device 230.
請再參考圖3，除此之外，為了確保第一模座220與第二模座210彼此能確實地閉閡，在本實施例中，亦可再配置一第三壓力感測器260於第一模座220與第二模座210之間且電性連接該第一壓力感測器240，從而讓第一模座220與第二模座210於每一次的射出成型前，都能達到完全閉閡的狀態。Please refer to FIG. 3 again. In addition, in order to ensure that the first mold base 220 and the second mold base 210 can be reliably closed, in the embodiment, a third pressure sensor 260 may be further disposed. The first mold base 220 and the second mold base 210 are electrically connected to the first pressure sensor 240, so that the first mold base 220 and the second mold base 210 can be reached before each injection molding. Completely closed state.
此舉讓射出成型模具200中的各個構件皆須達到所預定的位置，方能讓射出成型機300繼續下一個射出成型製程。一旦第一壓力感測器240與第三壓力感測器260的其 中之一未到達設定壓力，即代表此構件並未達到預定位置，因此便能在立即產生一斷路訊號，使射出成型機300停止動作，以藉此保護射出成型模具200中的相關構件。This allows the individual components in the injection molding die 200 to reach the predetermined position to allow the injection molding machine 300 to continue to the next injection molding process. Once the first pressure sensor 240 and the third pressure sensor 260 thereof If one of the components does not reach the set pressure, it means that the member does not reach the predetermined position, so that a disconnection signal can be immediately generated to stop the injection molding machine 300, thereby protecting the relevant member in the injection molding die 200.
另外，在本發明另一未繪示的實施例中，壓力感測器亦可常態地設置於射出成型機上，亦即使用者僅需在頂出裝置或模座上預留凹槽，當模座設置於射出成型機上後，再將壓力感測器裝設於此預留的凹槽。如此一來，便無須在每一組模具上配置壓力感測器，使用者可依據模具的設計需求，而在模具的相關構件中預留凹槽即可。此舉亦能降低壓力感測器的成本與增進射出成型的製程效率。In addition, in another embodiment of the present invention, the pressure sensor can also be normally disposed on the injection molding machine, that is, the user only needs to reserve a groove on the ejection device or the mold base. After the mold base is placed on the injection molding machine, the pressure sensor is installed in the reserved groove. In this way, it is not necessary to arrange a pressure sensor on each set of molds, and the user can reserve a groove in the relevant components of the mold according to the design requirements of the mold. This also reduces the cost of the pressure sensor and increases the efficiency of the injection molding process.
綜上所述，在本發明的上述實施例中，射出成型模具藉由壓力感測器而使射出成型機能監測構件是否達到預定的運動位置，因此能有效地避免射出成型模具中的構件彼此干涉而造成可能的損壞。再者，使用者可在射出成型模具中的任何構件中配置壓力感測器，藉以掌控在射出成型的製程中，射出成型模具的運動狀態，並進而增加製程良率與提高射出成型模具的使用壽命。In summary, in the above embodiment of the present invention, the injection molding die enables the injection molding machine to monitor whether the member reaches a predetermined movement position by the pressure sensor, thereby effectively preventing the components in the injection molding die from interfering with each other. And cause possible damage. Furthermore, the user can arrange a pressure sensor in any of the components in the injection molding mold, thereby controlling the movement state of the injection molding mold in the injection molding process, thereby increasing the process yield and improving the use of the injection molding die. life.
