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.

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.

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.

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,

The 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.

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.

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.

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.

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.

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.

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
