發明所屬技術領域機或塑膠射出成型機上，頂出用頂出機構之模具固本發明適用於例如壓鑄成型是有關具備著將成型品從模具内鎖裝置。、、習知之技術TECHNICAL FIELD The present invention is applicable to, for example, die-casting molding on a machine or a plastic injection molding machine. The present invention is applicable to, for example, die-cast molding, and relates to a device for locking a molded product from a mold. 、, Known technology

〇在形成塑膠等之樹脂用的射出成形機上，為了將成形时從模具中剝離而在模具固鎖裝置中配備了頂出機構。模，固鎖裝置是用來開閉模具，並在模具閉合狀態時施加既定之鎖模力於模具上之裝置。在上述模具固鎖裝置之頂出機構中，例如配置成可以出沒於於模具之模面内的頂出銷’在製品成形完而模具打開之狀態下讓此頂出銷突出而將製品取出。但是在習知之頂出機構中，頂出銷是利用與開閉模具所用作動器不同之獨立的作動器來加以驅動，因此使得模具固鎖裝置之構造變得複雜化而產生成本高漲之不利情況。〇Injection molding machines for forming resins, such as plastics, are equipped with an ejection mechanism in the mold locking device in order to peel them from the mold during molding. The mold and locking device is a device used to open and close the mold and apply a predetermined clamping force to the mold when the mold is closed. In the ejection mechanism of the mold locking device described above, for example, an ejection pin ′ which can be located in the mold surface of the mold is configured to allow the ejection pin to protrude while the product is formed and the mold is opened to take out the product. However, in the conventional ejection mechanism, the ejection pin is driven by an independent actuator that is different from the actuator used for the opening and closing mold, so that the structure of the mold locking device is complicated and the cost is disadvantageous.

在例如特公平4-2416號公報中已經揭示了將模具之開閉動作與頂出機構之動作以同一作動器來加以驅動之技術。圖22所示為利用特公平4-2416號公報中所揭示之模具固鎖裝置，將固定模具174與移動模具175予以固鎖，在射出成形完冷卻後利用移動模板110將移動模具175從固定模具174處分離開，同時也具備著以推出銷117來將成形品頂For example, Japanese Unexamined Patent Publication No. 4-2416 has disclosed a technique for driving the mold opening and closing operation and the ejection mechanism operation by the same actuator. FIG. 22 shows the use of the mold locking device disclosed in Japanese Patent Publication No. 4-2416 to lock the fixed mold 174 and the mobile mold 175. After the injection molding is cooled, the mobile mold 175 is fixed from the fixed mold The mold 174 is separated, and it is also equipped with a push pin 117 to eject the molded product.

Description of the invention (2) The ejection mechanism used. Specifically, it includes a crank arm 1 15 for moving the mold plate 11 back and forth, and a mold opening / closing motor 107 for driving the crank arm 1 15 is arranged on the inside of the movable mold plate 11 along the spring 112. The ejection plate 111 which is elastically pressured in its backward direction, and the ejection plate 103 which allows the front end of the ejection plate 111 to contact the ejection plate 111 and prevent the ejection plate 111 from retreating further when the ejection plate 111 is retracted to a predetermined position.

此類模具固鎖裝置是利用驅動曲軸臂115使得移動模板110產生移動而將移動模具175打開，及讓頂出板111觸及頂出桿103而限制頂出板ill之後退。在頂出板Hi之停止狀態下繼續讓移動模板11 〇後退時，經由彈簧丨丨2而保持在壓縮狀態之推出銷117則會相對突出於移動模具175。以此方式可以將成形品從移動模具175中頂出。再驅動曲轴臂115而讓移動模板11〇前進時，頂出板hi會自頂出桿1〇3 中脫離，此時推出銷11 7則利用彈簧112之施壓力而相對沒入於移動模具175内，而回復至固定位置處。發明欲解決之課題如上所述之模具固鎖裝置中具備著讓推出銷與模具之開閉操作連動而作用之頂出機構，除了可以使用於塑膠射出成形機外也可適用在壓鑄成形機上。但是在壓鑄成形機上所使用之成形材料為鋁合金等金屬溶液。因此射出至模具内之金屬熔液的一部分可能會飛濺至移動模板110上，而可能會沾附在配置於移動模板11〇内之彈簧112上。當彈簧112上有金屬熔液沾附凝固時就會This type of mold locking device uses the driving crankshaft arm 115 to move the movable mold plate 110 to open the movable mold 175, and allows the eject plate 111 to contact the eject rod 103 to restrict the eject plate ill from moving backward. When the moving platen 11 is moved backward in the stopped state of the ejector plate Hi, the ejection pin 117 which is maintained in a compressed state via the spring 丨 2 will relatively protrude from the moving mold 175. In this way, the molded article can be ejected from the movable mold 175. When the crank arm 115 is driven again to move the movable platen 110 forward, the ejection plate hi will disengage from the ejection rod 103. At this time, the ejection pin 11 7 is relatively submerged in the movable mold 175 by the pressure of the spring 112. And return to a fixed position. Problems to be Solved by the Invention The above-mentioned mold locking device includes an ejection mechanism that interlocks the ejection pin with the opening and closing operation of the mold. The ejection mechanism can be used not only in a plastic injection molding machine but also in a die-casting molding machine. However, the forming material used in the die-casting molding machine is a metal solution such as an aluminum alloy. Therefore, a part of the molten metal ejected into the mold may be splashed on the movable template 110, and may be attached to the spring 112 disposed in the movable template 110. When the molten metal adheres to the spring 112 and solidifies,

Description of the invention (3) The phenomenon of abnormal expansion and contraction of the spring 112 is generated. In the ejection mechanism described above, when the spring 112 cannot normally expand and contract phase = the ejection pin 117 moved by moving the template 110, for example, the movable mold 175 and the fixed mold 4 must be closed when the ejection operation of m is completed In this state, the push pin 117 cannot be returned to the predetermined position in the movable mold 175. There is a concern that the molding will occur when the molding is performed in a state protruding from the moving mold 175, especially when inserting the insert 2 in the mold to form the mold. When the ejection pin 117 protrudes, the mold will be damaged. The object of the present invention is to provide a mold locking device capable of interlocking with the opening and closing action of a mold and allowing the ejector pin to operate in view of the above problems.

線圈彈簧64，並施加使其相互隔離之作用移動模具52上。力在頂出板68及頂出板68是經由貫穿於移動模板51内來與可動板53相連結。由於是經由連結 ^53與頂出板68相連結，故可動板53與頂出銷63也相連 ~，並利用連動於移動模板51與可動板53間之相對移動而讓頂出銷63相對出沒於移動模具52之模具内面。接著針對上述構造之模具固鎖裝置丨的動作來加以說明0The coil springs 64 are applied to isolate the coil springs 64 from each other. The force ejection plate 68 and the ejection plate 68 are connected to the movable plate 53 through the moving template 51. Since it is connected to the ejection plate 68 through the connection ^ 53, the movable plate 53 is also connected to the ejection pin 63 ~, and the ejection pin 63 is relatively infested by the relative movement between the movable template 51 and the movable plate 53 On the inner surface of the mold of the moving mold 52. Next, the operation of the mold locking device with the above structure will be described.

在圓1所不狀態之模具固鎖裝置J中，固定模具92與移動模具52是處於鎖模狀態下。、 —由此狀態而驅動鎖模用之伺服馬達3〇，讓螺桿1〇6朝既定之方向回轉，並讓十字頭1〇5朝向開模方向M移動。當十子頭105朝向開模方向A1移動時，如囷7所示經由上述之肘節機構109使得移動模板51朝向連桿箱21移動，而相對於固定模具92將移動模具52打開。此時成形於固定模具92與移動模具52間所形成模穴中的壓鑄製品，就如圖7所示隨著移動模具52 —起移動。In the mold fixing device J in the state of circle 1, the fixed mold 92 and the movable mold 52 are in the mold clamping state. --- In this state, the servo motor 30 for mold clamping is driven, the screw 106 is rotated in a predetermined direction, and the crosshead 105 is moved toward the mold opening direction M. When the ten head 105 moves toward the mold opening direction A1, as shown in Fig. 7, the moving template 51 is moved toward the link box 21 via the above-mentioned toggle mechanism 109, and the moving mold 52 is opened relative to the fixed mold 92. At this time, the die-cast product formed in the cavity formed between the fixed mold 92 and the movable mold 52 moves together with the movable mold 52 as shown in FIG. 7.

當移動模板51移動至既定開模位置之極限開模位置pA 時，配置於可動板53上之掛鉤構件58就***連桿箱21上夾緊用構件24的***孔24a内。因此、可動板53是經由夾緊用構件24及掛鉤構件58而與連桿箱21相連結。在此處圖9為顯示可動板5 3經由連桿箱21所夾緊狀態時的側面視圖，圖9中之下半部分為移動模板5丨移動至極When the movable mold plate 51 is moved to the extreme mold opening position pA of the predetermined mold opening position, the hook member 58 disposed on the movable plate 53 is inserted into the insertion hole 24a of the clamping member 24 on the link box 21. Therefore, the movable plate 53 is connected to the link box 21 via the clamping member 24 and the hook member 58. Here, FIG. 9 is a side view showing a state in which the movable plate 53 is clamped by the link box 21, and the lower half in FIG. 9 is a moving template 5 丨 moved to the extreme

限開模位置PA時之狀態。如圖9所示當配置於可動板53上之掛鉤構件58***失緊用構件24的***孔24a内時，就驅動空氣缸25讓空氣缸 25上之活塞桿25a突出，並卡止在掛鉤構件58上之卡止凹部59中。以此方式’可動板5 3被連桿箱21所夾緊，而限制可動板53朝向開閉模方向A1或A2移動。接下來從上述狀態中，讓十字頭105繼續往開模方向 A1移動，如圓8所示讓移動模板51從極限開模位置pa處再繼續朝向開模方向A1移動至頂出位置PB為止。圓9中之上半部分所示為將移動模板51從極限開模位置PA處再繼績朝向開模方向A1移動至頂出位置pb為止時之狀態。由於可動板53是被連桿箱21所限制住，即使移動模板 51繼續朝向開模方向A1移動可動板53之移動也會受到阻止。因此而在移動模板51與可動板53之間產生了模具開閉方向A1或A2之相對移動了。由圖9中就可以了解，當在移動模板51與可動板5 3之間產生相對移動時線圈彈簧60就會被壓縮。接著如圖8所示，當可動板5 3之朝向開模方向A1移動受到阻止時，設置於移動模具52背後之頂出板68就會承受線圈彈簧64之施壓力而向移動模具52靠近。頂出板68靠近移動模具52後頂出銷63會突出於移動模具52外，而將移動模具52内之壓鑄製品頂出。The state when the mold opening position PA is limited. As shown in FIG. 9, when the hook member 58 disposed on the movable plate 53 is inserted into the insertion hole 24 a of the tightening member 24, the air cylinder 25 is driven so that the piston rod 25 a on the air cylinder 25 protrudes and is locked on the hook. In the locking recess 59 on the member 58. In this way, the movable plate 53 is clamped by the link box 21, and the movable plate 53 is restricted from moving toward the mold opening / closing direction A1 or A2. Next, from the above state, the crosshead 105 is continued to move in the mold opening direction A1, and the moving template 51 is moved from the extreme mold opening position pa to the mold opening direction A1 to the ejection position PB as shown by circle 8. The upper half of the circle 9 shows the state when the moving template 51 is moved from the extreme mold opening position PA and then toward the mold opening direction A1 to the ejection position pb. Since the movable plate 53 is restricted by the link box 21, even if the movable platen 51 continues to move toward the mold opening direction A1, the movement of the movable plate 53 is blocked. Therefore, a relative movement between the mold opening and closing direction A1 or A2 occurs between the movable die plate 51 and the movable plate 53. As can be understood from Fig. 9, the coil spring 60 is compressed when a relative movement occurs between the movable template 51 and the movable plate 53. Next, as shown in FIG. 8, when the movement of the movable plate 53 toward the mold opening direction A1 is prevented, the ejection plate 68 provided behind the moving mold 52 will approach the moving mold 52 under the pressure of the coil spring 64. When the ejection plate 68 approaches the movable mold 52, the ejection pin 63 projects out of the movable mold 52, and ejects the die-casting product in the movable mold 52.

2197-4995-PF(N)；ahddub.ptd 第17頁 558491 五、發明說明（14) 以此方式就完成將壓鑄製品W從模具中取出之作業。接下來由上述之狀態中將模具固鎖用伺服馬達3 〇之回轉方向加以倒轉，讓移動模板5 1從頂出位置pb處朝向極限開模位置PA移動。此時相對於連桿箱21而言可動板53仍是在被限制的狀態。當移動模板51往極限開模位置pa移動時，就如圖7所示狀態可動板53碰及導桿55前端之擋塊56而相對於移動模板51回復至固定位置處。同時、頂出銷63會確實的沉入移動模具52之模面内，而使被壓縮之線圈彈簧6〇回復原狀。2197-4995-PF (N); ahddub.ptd page 17 558491 V. Description of the invention (14) In this way, the operation of removing the die-casting product W from the mold is completed. Next, in the above state, the rotation direction of the servo motor 30 for mold locking is reversed, and the moving template 51 is moved from the ejection position pb toward the extreme mold opening position PA. At this time, the movable plate 53 is still restricted with respect to the link box 21. When the moving template 51 moves to the extreme mold opening position pa, the movable plate 53 hits the stopper 56 at the front end of the guide lever 55 as shown in Fig. 7 and returns to the fixed position with respect to the moving template 51. At the same time, the ejection pin 63 will sink into the mold surface of the movable mold 52 surely, and the compressed coil spring 60 will return to its original state.

在此狀態下可動板53是相對於連桿箱21受到限制，而且是位於與移動模板51對應之固定位置處，故移動模板51 就被阻止朝向閉模方向A2來移動。也就是說，在開模狀態下只要是經由空氣缸25之夾緊動作未解除時’移動模板51就無法朝向閉模方向A2移動，即使在模具固鎖用伺服馬達3 0產生誤動作時也能防止移動模板51朝向閉模方向A2移動。In this state, the movable plate 53 is restricted with respect to the link box 21 and is located at a fixed position corresponding to the movable template 51, so the movable template 51 is prevented from moving toward the mold closing direction A2. In other words, in the mold opening state, as long as the clamping action via the air cylinder 25 is not released, the 'moving platen 51 cannot move toward the mold closing direction A2, and even when a malfunction occurs in the mold fixing servo motor 30, The moving template 51 is prevented from moving in the mold closing direction A2.

在此狀態下再次進行模具固鎖之場合，當檢知到針對模具固鎖裝置1之控制裝置所發出的模具固鎖信號時，驅動空氣缸2 5使付活塞桿2 5 a相對於掛釣構件5 §沉下，而將可動板53之夾緊動作解除。如上所述，使用本實施形態之模具固鎖裝置1時可以不需要頂出用的作動器’經由移動模板51和開模動作間之連動就可以將壓鑄製品從移動模具52中頂出。同時在本實施形態之模具固鎖裝置1中，讓移動模板When the mold lock is performed again in this state, when the mold lock signal sent to the control device of the mold lock device 1 is detected, the air cylinder 2 5 is driven to make the auxiliary piston rod 2 5 a relative to the fishing The member 5 § sinks, and the clamping action of the movable plate 53 is released. As described above, when the mold locking device 1 according to this embodiment is used, the die-casting product can be ejected from the movable mold 52 without interlocking between the movable mold 51 and the mold opening operation. At the same time, in the mold locking device 1 of this embodiment, the moving template is allowed

When moving toward pa, the ejection pin 63 can be surely sunk into the moving die surface. That is, in this embodiment, instead of using the pressing force of the coil spring 60 to let the ejection pin 63 be immersed in the mold surface of the moving mold 52, it is performed by the movement of the moving template 51. Where the coil spring ㈤ cannot be properly extended and contracted due to the solidification of the metal dazzling liquid on the spring 60, the ejection pin 63 can still be returned to a fixed position. _ Also in this embodiment, the movable plate 53 is restricted by the link box 21, so it has a safety mechanism that can reliably prevent the moving template 51 located at the extreme mold opening position PA from moving in the mold closing direction A2 due to a malfunction.

在此可動板53之連桿箱21侧的面上，設置著複數個掛鉤構件201。在此掛鉤構件2〇1之前端部位置办氣缸25之活塞桿25a用的卡止凹部2〇2。此掛鉤形狀雖然與第1實施形態中之掛鉤構件58有若但具有與掛鉤構件58相同之機能。、還有在可動板53之兩側部上，設置著卡止構件2〇3。在此卡止構件203之外側面上作出卡止凹部2〇3&。在移動模板51之兩側部上，與位於固定位置之可動板 53上的卡止構件203相對向位置處分別設置著空氣缸21〇。A plurality of hook members 201 are provided on a surface of the movable plate 53 on the link box 21 side. The locking recess 202 for the piston rod 25a of the air cylinder 25 is located at the front end position of the hook member 201. This hook shape has the same function as the hook member 58 although it has the same shape as the hook member 58 in the first embodiment. Also, on both sides of the movable plate 53, locking members 203 are provided. A locking recess 203 & is formed on the outer side of the locking member 203. On both sides of the movable template 51, air cylinders 21 are provided at positions opposite to the locking members 203 on the movable plate 53 at a fixed position.

That is, it cannot be moved in the mold opening / closing direction A1 or A2 with respect to the moving template 51. The operation of the mold locking device having the above-mentioned structure will be described next. In the mold locking device in the state shown in Fig. 10, the fixed mold 92 and the movable mold 52 are in the mold locked state, and the movable template 51 is located at the exposed fixed position. In this state, the air cylinder 21 is driven so that the piston rod 211 protrudes outward and the movable plate 53 is restricted with respect to the movable template 51. In this state, as in the case of the first embodiment, moving the mold

板51往開模方向A1移動時，就如圖"所示直到移移動至極限開模位置PA為止，掛鉤構件2〇1之前端會入夾緊用構件24之***孔24a内。以此狀態讓空氣缸25作動時，空氣缸25上之活塞桿就卡止於掛鉤構件201上的卡止凹部2〇2中，並將其夾緊。以此方式可動板5 3就相對於連桿箱21而受到限制。When the plate 51 is moved in the mold opening direction A1, as shown in FIG. "Until it is moved to the extreme mold opening position PA, the leading end of the hook member 201 is inserted into the insertion hole 24a of the clamping member 24. When the air cylinder 25 is operated in this state, the piston rod on the air cylinder 25 is locked in the locking recessed portion 202 of the hook member 201 and clamped. In this way, the movable plate 53 is restricted with respect to the link box 21.

當可動板5 3經由空氣缸2 5而相對於連桿箱21受到限制後，接下來如圓12所示將空氣缸21〇上之活塞桿2 u降下，而讓可動板53從相對於移動模板51所受到之限制中加以解除。如此則可動板53就可以相對於移動模板51而移動了。接下來如圓13所示將移動模板51由極限開模位置PA進一步朝向開模方向A1移動，並一直移動至頂出位置pB處為止。以此方式讓可動板53相對於移動模板51產生閉模方向 A2之相對移動，而利用頂出銷將壓鑄製品頂出。在此狀態下’可動板5 3就從移動模板51之固定位置處移出。一旦完成壓鑄製品之頂出作業後，如圖14所示移動模板51再次移動至極限開模位置pa處。如此可動板53就又回歸至移動模板51上之固定位置處。同時讓頂出銷63確實的沉入移動模具52之模面内。然後將空氣缸210之活塞桿211 往外伸出，而相對於移動模板51將可動板53再次加以限制。在以此狀態下，可動板53是相對於連桿箱2 1受到限制，而且相對於移動模板5 1而言是位於固定之位置，故能After the movable plate 53 is restricted relative to the link box 21 via the air cylinder 25, the piston rod 2u on the air cylinder 21o is lowered as shown by circle 12, and the movable plate 53 is moved relative to The restrictions imposed on the template 51 have been lifted. In this way, the movable plate 53 can be moved relative to the movable template 51. Next, as shown by circle 13, the moving template 51 is further moved from the extreme mold opening position PA toward the mold opening direction A1, and continues to move to the ejection position pB. In this way, the movable plate 53 is caused to move relative to the movable mold plate 51 in the mold closing direction A2, and the die-casting product is ejected by the ejection pin. In this state, the 'movable plate 53' is removed from the fixed position of the movable template 51. Once the ejection operation of the die-cast product is completed, the moving die plate 51 is moved to the extreme die opening position pa again as shown in FIG. In this way, the movable plate 53 is returned to the fixed position on the movable template 51 again. At the same time, the ejection pin 63 is surely sunk into the die surface of the movable die 52. Then, the piston rod 211 of the air cylinder 210 is extended outward, and the movable plate 53 is restricted again with respect to the moving template 51. In this state, the movable plate 53 is restricted with respect to the link box 21 and is located at a fixed position with respect to the movable template 51, so that

Description of the invention (19) -------- It is enough to prevent the soil to move the template 51 toward the mold closing direction A2. In other words, when the mold is locked, the mold plate 51 cannot move toward the mold closing direction A2 until the clamping by the air cylinder 25 is released, even if the feeding motor for mold clamping malfunctions. It can also prevent the moving template 51 and the mold direction A2 from moving. When the mold clamping is performed again in this state, when the mold clamping signal from the control device of the mold clamping device 1 is detected, the air cylinder 25 is driven so that the piston rod 25a thereof sinks into the hook member 58 relatively. , And release the clamping action. At this time, the movable plate 53 is not released from the clamping state due to the action of the air cylinder 210. Therefore, the movable plate 53 can be reliably positioned at the fixed position of the movable template 51 until the ejecting operation is performed again. As described above, in this embodiment, except for the relative movement between the movable plate 53 and the movable platen 51, the air cylinder 21 is used to keep the movable plate 53 in a clamped state at all times, so that the eject pin 63 can be reliably fixed. It is submerged in the mold surface of the moving mold 52, and the position of the ejection pin 63 can be controlled accurately. In this embodiment, similarly to the first embodiment described above, the safety mechanism and the ejection mechanism can be used in combination with each other to simplify the device configuration. In the above-mentioned embodiment, although the case where the air cylinders 25 and 21 0 are used as actuators has been described, it is also possible to use, for example, hydraulic irises, motors, powerful electromagnets and the like that have good reactivity. Device. In the above-mentioned embodiment, although it is provided at a plurality of positions,

Description of the invention (20) The air cylinders 2 and 5, 210 can be placed, or they can only be set in a single position. At the same time, in the above-mentioned embodiment, the air cylinders 25 and 210 are separately provided, but they can also be integrated as shown in FIG. 15. In FIG. 15 (a), air cylinders 301 are provided at both ends of the movable plate 53 to allow the piston rod 3 02 to protrude outward. At the same time, a locking recess 304 for locking the piston rod 302 of the air cylinder 301 is made at a certain position of the moving template 51. On the other hand, a locking member 305 is provided on the link box 21, and a locking recess _305a in which the piston rod 302 of the air cylinder 301 can be locked in this member can be made. When the mold is locked as shown in Figure 1 In the state shown in 5 (a), the movable plate 53 can be clamped to a fixed position on the movable template 51 via the air cylinder 301. As shown in FIG. 15 (b), when the movable template 51 is moved straight to the extreme mold opening position, the piston rod 30 of the air cylinder 301 protrudes in the opposite direction and is locked on the locking member 305. In this way, the link box 21 is caused to restrict the movable plate 53. At the same time, the movable template 51 is also released from the restricted state with respect to the movable plate 53. In this way, the movable plate 5 3 which is moved outward at the fixed position of the optional plate 51 toward the mold is opened and closed, and the number of air rainbows used is reduced, so that the movable plate 5 3 is restricted from the movable mold 'or restricted to the limit. The structure of the mold opening direction movement can reduce the cost.

558491 五、發明說明（21) 【第3實施形態】圖1 6所示為本發明第3實施形態相關模具固鎖裝置中連桿箱及移動模板之周邊構成平面圖。在上述之第1及第2實施形態中如未將移動模板51移動至開模極限制置PA時，就無法進行成形品之頂出動作。例如在成形品厚度較薄等之場合，即使不將移動模板51移動至極限開模位置PA也能將成形品頂出。如果一直都需將移動模板51移動至極限開模位置pa時，就存在有作業周期長之不經濟狀況。在本實施形態中是針對即使不將移動模板51移動至極 ^ 限開模位置PA處，也能夠進行頂出動作，也就是說，具備著可以變更當要開始限制可動板時之移動模板5 1位置的構成加以說明。本實施形態相關之模具固鎖裝置與上述第2實施形態所述之模具固鎖裝置基本上具有相同之構成，差異點僅在於移動模板51中之局部構成，其它部分之構成則相同。故在相同構成部分及具有相同之基本機能構成部分使用相同之符號來加以說明。558491 V. Description of the invention (21) [Third embodiment] Fig. 16 is a plan view showing the peripheral structure of the link box and the movable template in the mold fixing device according to the third embodiment of the present invention. In the first and second embodiments described above, if the moving template 51 is not moved to the mold opening limiter PA, the ejection operation of the molded product cannot be performed. For example, when the thickness of the molded product is thin, the molded product can be ejected without moving the moving die 51 to the extreme mold opening position PA. If it is always necessary to move the movable template 51 to the extreme mold opening position pa, there is an uneconomical situation in which the operation cycle is long. In this embodiment, the ejection operation can be performed without moving the movable template 51 to the extreme opening position PA. That is, the movable template 51 can be changed when the movable plate is to be restricted. The structure of the position will be explained. The mold locking device related to this embodiment has basically the same structure as the mold locking device described in the second embodiment above, and the difference is only in the partial structure of the moving template 51, and the other portions have the same structure. Therefore, the same symbols are used to describe the same components and components with the same basic functions.

在圖16中於連桿箱21中支持部22之前端部上設置著上述之空氣缸25。還有在可動板53上設置著複數個朝向模具開閉方向A1及A2延伸之掛鉤構件2〇1。在此掛鉤構件2〇1之前端部上形成著作為卡止空氣缸25之活塞連桿25a用的卡止凹部202。此掛鉤構件201與第2實施形態中之掛鉤構件 201在形狀上並無差異且具有相同之機能。The air cylinder 25 described above is provided on the front end of the support portion 22 in the link box 21 in Fig. 16. The movable plate 53 is provided with a plurality of hook members 201 extending in the mold opening and closing directions A1 and A2. A locking recess 202 for locking the piston rod 25a of the air cylinder 25 is formed on the front end portion of the hook member 201. This hook member 201 has no difference in shape from the hook member 201 in the second embodiment and has the same function.

複數個之空氣缸210並非固定在移動模板51上，而是分別被固定在滑動塊（Slider)250上。滚珠螺桿2 51旋入在此滑動塊2 5 0之一端側上。此滾珠螺桿251之一端部是開放狀態，另一端部是連接至固定於移動模板51之伺服馬達252的回轉軸252a上。並利用沿著模具開閉方向A1及A2配置之滾珠螺桿251以可回轉方式來加以支持。在滑動塊250之另一端側上***導桿（Guide rod)253❶此導桿253之一端部是開放狀態，另一端部是利用固定構件254而被固定於移動模板51上。導桿253是沿著模具開閉方向A1及A2而配置。利用導桿253將滑動塊250以可沿著模具開閉方向A1及A2任意移動之方式來加以支持。滑動塊250可以沿著上述之滾珠螺桿251及導桿253朝向模具開閉方向A1及A2任意移動。當伺服馬達252回轉時伺服馬達2 5 2之回轉力變換成直動力，讓滑動塊250沿著模具開閉方向A1及A2而移動。並利用伺服馬達252之回轉位置控制來進行滑動塊250在模具開閉方向A1及A2之定位。在圖16中可動板53是可以沿著導桿55而任意移動，在此可動板53上形成著用來與空氣缸210上之活塞連桿211的前端部相互崁合之卡止凹部53a。此卡止凹部53a與在第2 實施形態中所說明位於卡止構件20 3上之卡止凹部203a具有相同之機能。當活塞連桿211伸長而崁合入可動板53之卡止凹部5 3a 時，可動板53就受到限制無法離開移動模板51之固定位置The plurality of air cylinders 210 are not fixed on the moving template 51, but are fixed on the slider 250 respectively. A ball screw 2 51 is screwed onto one end side of this slider 250. One end of the ball screw 251 is in an open state, and the other end is connected to a rotary shaft 252a of a servo motor 252 fixed to the movable platen 51. A ball screw 251 arranged along the mold opening and closing directions A1 and A2 is supported in a rotatable manner. A guide rod 253 is inserted on the other end side of the slide block 250. One end portion of the guide rod 253 is in an open state, and the other end portion is fixed to the movable template 51 by a fixing member 254. The guide rods 253 are arranged along the mold opening and closing directions A1 and A2. The guide block 253 is used to support the slide block 250 so that it can be arbitrarily moved in the mold opening and closing directions A1 and A2. The slide block 250 can be arbitrarily moved in the mold opening and closing directions A1 and A2 along the above-mentioned ball screw 251 and guide rod 253. When the servo motor 252 rotates, the turning force of the servo motor 2 5 2 is converted into direct power, and the slide block 250 is moved along the mold opening and closing directions A1 and A2. The rotation position control of the servo motor 252 is used to position the slide block 250 in the mold opening and closing directions A1 and A2. In Fig. 16, the movable plate 53 can be arbitrarily moved along the guide rod 55. Here, the movable plate 53 is formed with a locking recess 53a for engaging with the front end portion of the piston rod 211 of the air cylinder 210. This locking recessed portion 53a has the same function as the locking recessed portion 203a located on the locking member 203 described in the second embodiment. When the piston connecting rod 211 is extended and engaged with the locking recess 5 3 a of the movable plate 53, the movable plate 53 is restricted from leaving the fixed position of the movable template 51.

Description of the invention (23). That is, it cannot move toward the mold opening and closing directions A1 and A2 with respect to the moving template 51. The restriction position of the movable plate 53 is determined by the positions of the air cylinder 210 in the mold opening and closing directions A1 and A2. In other words, by setting the slide block 25 to the desired position of the mold opening and closing directions A1 and A2, the restricted position of the movable plate 53 can be adjusted to the desired position. The position adjustment mechanism of the present invention is composed of the above-mentioned slide block 250, a ball screw 251, a servo motor 252, and a guide rod 253.

接下來將具有上述構成之模具固鎖裝置的動作參照圖 17及圊18加以說明如下。 ' 當想要將開始進行成形品頂出動作而將時移動模板51 從上述極限開模位置p A變更至其它位置之場合，如圓17所示將滑動塊250從移動模板51朝向開模方向A1移動至所需之距離La處。同時利用空氣缸210讓可動板53成為被限制狀態。又，距離La是開始進行成形品頂出動作時移動模板 51所處位置之變更量。當以距離La來移動滑動塊250時，可動板53與移動模板5 1間之相對位置就隨之變更。Next, the operation of the mold fixing device having the above-mentioned structure will be described with reference to Figs. 17 and 18. '' When you want to start the ejection of the molded product and move the moving template 51 from the above-mentioned extreme mold opening position p A to another position, move the slide block 250 from the moving template 51 toward the mold opening direction as shown by circle 17 A1 moves to the required distance La. At the same time, the air cylinder 210 is used to bring the movable plate 53 into a restricted state. The distance La is the amount of change in the position of the moving template 51 when the ejection operation of the molded product is started. When the slider 250 is moved by the distance La, the relative position between the movable plate 53 and the movable plate 51 changes accordingly.

在圖17中以移動模具52及固定模具92在閉模狀態下時之移動模板51位置當作閉模位置％時，當成形品之成形結束後移動模板51會從閉模位置PC朝向開模方向A1而移動。接下來如圖18所示，將移動模板51定位在位於極限開模位置PA别面之頂出動作開始位置pD處。此頂出動作開始位置PD是如圖18所示位於從極限開模位置pA以距離u朝向In FIG. 17, when the position of the moving mold 51 when the movable mold 52 and the fixed mold 92 are in the closed state is regarded as the mold closing position%, when the molding of the molded product is completed, the moving mold 51 will move from the closed position PC to the mold opening. Move in direction A1. Next, as shown in Fig. 18, the movable template 51 is positioned at the ejection start position pD located on the other side of the extreme mold opening position PA. The ejection start position PD is located at a distance u from the extreme mold opening position pA as shown in FIG. 18.

558491 五、發明說明（24) 開模方向A2靠近之處。當移動模板51被定位於頂出動作開始位置pD後，空氣缸25之活塞連桿25a就伸長並使得活塞連桿25a崁合在掛鉤構件201之卡止凹部202中。當活塞連桿25a嵌合在掛鉤構件2〇1之卡止凹部202中後’空氣缸2 1 0之活塞連桿2 11就縮回，而將可動板53從被空氣缸21 0之限制狀態中解除。此後之動作和上述第2實施形態完全相同，移動模板 51從頂出動作開始位置PD繼續朝向開模方向A1移動而進行成形品之頂出。如上所述由於本實施形態可以變更開始進行成形品頂出動作時之頂出動作開始位置，故不需要在每次進行成形品之頂出動作時都要將移動模板51從閉模位置pc —直移動至極限開模位置PA。因此就可以縮短壓铸機之工作週期。又’由於可以利用伺服馬達等之作動器來調整作為第 1限制裝置用的空氣缸21 0之位置，故能夠以例如將模具規格輸入控制裝置中之方式，對應於此模具規格而進行頂出動作開始位置之自動調整。還有’雖然在本實施形態中是作成利用作動器來調整作為第1限制裝置用的空氣缸210之位置，也可以配置成以手動方式來相對移動模板51而調整空氣缸210之位置之構成0558491 V. Description of the invention (24) Where the mold opening direction A2 is close. When the moving template 51 is positioned at the ejection start position pD, the piston connecting rod 25a of the air cylinder 25 is extended and the piston connecting rod 25a is engaged in the locking recess 202 of the hook member 201. When the piston connecting rod 25a is fitted in the locking recess 202 of the hook member 201, the piston connecting rod 2 11 of the air cylinder 2 1 0 is retracted, and the movable plate 53 is removed from the restricted state by the air cylinder 2 10 Dismissed. The subsequent operations are exactly the same as in the second embodiment described above. The moving template 51 continues to move from the ejection start position PD toward the mold opening direction A1 to eject the molded product. As described above, since this embodiment can change the ejection start position when the ejection operation of the molded product is started, it is not necessary to move the moving template 51 from the mold closing position pc every time when the ejection operation of the molded product is performed. Move straight to the limit opening position PA. Therefore, the working cycle of the die casting machine can be shortened. Since the position of the air cylinder 21 0 as the first restricting device can be adjusted by an actuator such as a servo motor, it is possible to eject the mold according to the mold specifications by, for example, inputting the mold specifications into the control device.

同之機能。又’在掛鉤構件58之轴部上具備著螺旋部58a，利用將此螺旋部58a螺合在可動板53上所形成之螺栓孔内而固定於可動板53上。因此經由回轉掛鉤構件58可以讓掛鉤構件58相對於可動板53而調整位置。也就是說，可以經由轉動掛鉤構件58 之方式來調整卡止凹部59與可動板53間在模具開閉方向A1 及A2上之相對位置。本發明之位置調整機構是由上述之滑動塊25〇、滾珠螺桿251、伺服馬達252及導桿253所構成。還有，與形成於掛鉤構件58上之螺紋部58a及形成於可動板53上之螺紋部58a螺合之螺孔也進一步構成本發明之位置調整機構。接下來將具有上述構成之模具固鎖裝置的動作參照圓 2 0及圖21加以說明如下。當要開始進行成形品頂出動作將移動模板5丨位置從上述極限開模位置PA變更至其它位置之場合，如圖2〇所示將滑動塊250從連桿箱21朝向閉模方向A2移動至所需之距離Same function. Further, a spiral portion 58a is provided on the shaft portion of the hook member 58, and the spiral portion 58a is screwed into a bolt hole formed in the movable plate 53 to be fixed to the movable plate 53. Therefore, the position of the hook member 58 relative to the movable plate 53 can be adjusted via the turning hook member 58. That is, the relative positions of the locking recess 59 and the movable plate 53 in the mold opening and closing directions A1 and A2 can be adjusted by rotating the hook member 58. The position adjusting mechanism of the present invention is composed of the above-mentioned slide block 250, a ball screw 251, a servo motor 252, and a guide rod 253. The screw holes 58a formed on the hook member 58 and the screw holes 58a formed on the movable plate 53 are screwed to form the position adjusting mechanism of the present invention. Next, the operation of the mold locking device having the above configuration will be described with reference to circles 20 and FIG. 21 as follows. When the ejection operation of the molded product is to be started and the position of the moving template 5 丨 is changed from the above-mentioned extreme mold opening position PA to another position, as shown in FIG. 20, the slide block 250 is moved from the link box 21 toward the mold closing direction A2.
