In the partial diagram (a) in the drawing, the central claw portion is pushed against the die-cast product. A state before hitting is shown, and a partial view (b) in the figure shows a state when the central nail portion is abutted against the die-cast product.

  As shown in FIGS. 1 and 2, the center gripping part 11 is a member that is inserted between two die-cast products W when the die-cast product W is taken out. The central gripping portion 11 includes a shaft-like member 12 extending upward, and is attached to the shaft-like member 12 via a shaft member extending horizontally in the left and right positions of the upper side and the central portion. Four coil springs 13 as elastic bodies are arranged. The four coil springs 13 have a strong elastic force and are attached to the body of the hand 10 for taking out the die-cast product. Accordingly, the central gripping portion 11 has a configuration in which the central gripping portion 11 is suspended in a state in which it can move (swing or slide) via the four coil springs 13 and the single shaft-like member 12. With this configuration, the central gripping portion 11 according to the present embodiment is arranged in a state where it can move (swing or slide) between the two die-cast products W.

  Further, in the central grip 11, two central claws 11 a shown in FIGS. 4 and 5 are arranged inside the central grip 11. The two central claw portions 11a are arranged on the left and right outer sides from the inside of the central gripping portion 11 toward the two die cast products W after the central gripping portion 11 is inserted between the two die cast products W. It is comprised so that it can protrude in a direction.

  Here, the operation mechanism of the two central claws 11a installed in the central grip 11 will be described with reference to FIG. 5. A slope member having a slope at the root of the two central claws 11a. 11b is installed, and a pair of right and left slope members 11b are arranged so as to form a substantially V-shaped groove. Further, a wedge member 11c whose outer shape is substantially V-shaped is disposed in correspondence with the substantially V-shaped groove formed by the pair of left and right slope members 11b. When the wedge member 11c is pushed in the direction indicated by symbol α in FIG. 5 (a), the pair of left and right slope members 11b move in a direction to open in the left and right direction by the action of the wedge shape. . As a result, the two central claws 11a can project and move in the left-right direction indicated by the symbol β in the fractional view (b) of FIG. With the wedge mechanism described with reference to FIG. 5, the two central claw portions 11 a installed in the central grip portion 11 can project toward the inner side surfaces of the two die-cast products W. .

  On the other hand, the outer arm portion 21 has a configuration in which the outer sides of the two die-cast products W are pressed and gripped, as is apparent with reference to FIGS. 1 and 2. The outer arm portion 21 according to the present embodiment is configured as an arm member that can be tilted toward the die-cast product W, and one on each outer side of the two die-cast products W, two in total. It is an arranged member. In each of the two outer arm portions 21, two outer claw portions 21a for pressing the outer side of the die-cast product W are disposed. That is, in each of the two die-cast products W, the inner side surface is pressed by one central claw portion 11a, and the outer side surface is pressed by two outer claw portions 21a (in FIG. 4). (Refer to the state below the paper surface indicated by symbol (b)). Such a configuration is a mechanism for supporting the die-cast product W by the three claw portions 11a and 21a at three points. Therefore, according to the die-cast product take-out hand device 10 according to the present embodiment, a so-called multiple die-casting method. Therefore, even a plurality of die-cast products W formed simultaneously can be reliably and safely removed from the mold.

  In addition, as shown in FIGS. 1 to 3, eight ejection nozzles 31 extending downward are disposed below the die-cast product take-out hand device 10 according to the present embodiment. Using these eight ejection nozzles 31, a release agent is ejected to the cavity forming portion of the mold (movable mold 62) from which the two die-cast products W are removed, or air is ejected. This makes it possible to carry out a continuous die casting method using a mold.

  The configuration of the die-cast product take-out hand device 10 according to the present embodiment has been described above. Next, the operation of the die-cast product takeout hand device 10 according to the present embodiment will be described with reference to FIGS. Here, FIG. 6 to FIG. 10 are diagrams for explaining the operation of the die-cast product take-out hand device according to the present embodiment.

  In FIG. 6, molten metal melt is injected and injected into a cavity formed in a mating surface of a fixed mold 61 and a movable mold 62, which are a pair of molds that can be opened and closed, and the molten metal is cooled and hardened. When the die-cast product W is molded and the movable die 62 is opened from the state, the fixed die 61 and the movable die 62 are separated and opened, and the die-cast product W molded with respect to the movable die 62 remains. It is shown. 6 to 10, only one die-cast product W is drawn because the side view is shown. However, in FIGS. 6 to 10, two pieces of the die-cast product W are overlapped on the back side and the front side of the page. A die-cast product W is arranged.

  In order to take out the die-cast product W from the movable mold 62 shown in the state of FIG. 6, the die-cast product take-out hand device 10 moves between the open fixed mold 61 and the movable mold 62 as shown in FIG. 7. At this time, the position adjustment of the die-cast product take-out hand device 10 is performed so that the center gripping portion 11 has a height located between the two die-cast products W left and right.

  Next, as shown in FIG. 8, the die-cast product take-out device 10 moves toward the two die-cast products W, and the center gripping portion 11 is inserted between the two die-cast products W. In addition, after the central gripping portion 11 is inserted between the two die-cast products W, the above-mentioned wedge mechanism is operated, so that the two central claw portions 11a arranged inside the central gripping portion 11 are left and right. It protrudes toward the direction and presses the inner side surface of the two die-cast products W. Furthermore, after the two central claw portions 11a protrude, the two outer arm portions 21 tilt toward the die-cast product W, and the two outer claw portions 21a included in each of the two outer arm portions 21 are provided. The outer side surfaces of the two die cast products W are pressed. By these operations, the two die-cast products W are supported at three points by the three claw portions 11a and 21a, and a reliable gripping state by the die-cast product take-out hand device 10 is realized.

  When a reliable gripping state of the two die-cast products W by the die-cast product take-out device 10 is realized, the die-cast product take-out hand device 10 moves horizontally in the direction of the fixed die 61 as shown in FIG. From 62, two die-cast products W are completely removed. Thereafter, the die-cast product take-out hand device 10 is retreated from between the fixed die 61 and the movable die 62 which are opened by moving upward as shown in FIG. Further, in the middle of the retreat, eight ejection nozzles 31 extending downward from the die-handling product take-out hand device 10 are arranged at positions facing the movable mold 62, and two ejection nozzles 31 are used by using the eight ejection nozzles 31. A release agent may be ejected or air may be ejected to the cavity forming portion of the movable mold 62 from which the die-cast product W has been removed. By performing such an operation, it is possible to carry out a continuous die casting method using the dies 61 and 62. Thus, the two die-cast products W can be gripped with equal force by the central gripping portion 11 and the outer arm portion 21 that move (swing or slide).

  As mentioned above, although preferred embodiment of this invention was described, the technical scope of this invention is not limited to the range as described in the said embodiment. Various modifications or improvements can be added to the embodiment.

  For example, in the above-described embodiment, the apparatus configuration in the case where two die-cast products W are simultaneously taken out from the movable mold 62 has been described. However, the die-cast product take-out device according to the present invention has three or more die-cast products W. It is possible to configure as an apparatus for simultaneously taking out from one side of the mold.
