Accordingly, as the piston of the rotary cylinder 34 moves forward or backward, the rotary piece 33, the first rotary shaft 31, and the rotary block 32 rotate left or right together. At this time, the rotation angle of the rotary block 32 is rotated at an angle between about 0 ° to 90 °.

The second rotating unit 4 includes a second rotating shaft 41 and a motor 42.

The second rotary shaft 41 passes through the lower portion of the vertical panel 322 and is installed on the vertical panel 322, and the front end is coupled to the rotary plate 51.

When the reciprocating piece 53 protrudes and moves toward the molten metal, the bucket 7 is positioned at the upper part of the molten metal. At this time, the rotating cylinder 62 is operated to rotate the rotating piece 61 while the bucket 7 rotates downward. (See Figure 7)

After the bucket 7 rotates downward, the lifting cylinder 23 is operated to lower the lifting block 22 (see Fig. 8).

When the elevating block 22 descends, the bucket 7 is locked into the molten metal, and the elevating block 22 is raised while rotating the bucket 7 upward by operating the rotation cylinder 62 and the elevating cylinder 23 simultaneously. Let's do it. Accordingly, the bucket 7 spreads the molten metal contained in the molten metal (see FIGS. 9 and 10).

When the molten metal is pumped into the bucket 7, the reciprocating cylinder 54 is operated to transfer the reciprocating piece 53 to the rear, and after the reciprocating piece 53 is transferred to the rear, the rotary cylinder 34 is operated. (See FIG. 11)

When the rotary cylinder 34 operates, the rotary block 32 and the bucket 7 rotate on the plane to the left. Then, the reciprocating cylinder 54 is operated to advance the reciprocating moving piece 53 so that the bucket 7 is located at the inlet of the forging device. (See FIGS. 12 and 13).

When the bucket 7 reaches the upper portion of the inlet of the forging device, the motor 42 is operated to rotate the second rotating shaft 41. When the second rotary shaft 41 rotates, the slide moving part 5 and the bucket 7 rotate, and the bucket 7 rotates to pour the molten metal contained in the bucket 7 into the inlet of the forging device to inject molten metal. (See Figures 14 and 15)

When the molten metal injection is completed, the motor 42 is operated to rotate the bucket 7 to its original position, and when the bucket 7 is restored to its original position, the reciprocating cylinder 54 is operated to transfer the reciprocating piece 53 to the rear. Let's do it.

Therefore, the present invention can reduce the production time and improve the productivity by supplying the molten metal contained in the molten metal to the forging apparatus within a predetermined time by repeatedly performing the above operating sequence. In addition, since the operation is performed in the same time from the first stage operation to the last stage operation, by supplying the molten metal with the same temperature to the forging device every time the product is manufactured, it is possible to minimize the deviation between forging products and improve the quality. At the same time, the failure rate can be minimized. In addition, since the automatic molten metal injection device of the present invention instead of a dangerous operation is replaced by the present invention, it is possible to prevent a safety accident for human injury and to prevent the occurrence of defective products by always supplying a certain amount of molten metal to the forging device. have. Furthermore, by preventing the mistake of pouring molten metal onto the forging apparatus, it is possible to prevent the forging apparatus from malfunctioning and to prolong the life of the forging apparatus.

In addition, the present invention by installing the third rotary part 6 in the reciprocating moving piece 53, only when the bucket (7) to move when the molten metal is pumped out, the molten metal can be pumped out with a minimum of operation to minimize the accident rate have. That is, when discharging molten metal, which is a dangerous operation, the other components of the apparatus move only in the stationary state without moving the bucket 7, thereby minimizing malfunctions and accidents and thus saving energy. The area can be minimized to minimize interference with obstacles.
