[Detailed Description of the Invention] <Industrial Application Field> This invention is a machine that melts a molten metal from a holding furnace by swinging and vertically moving an arm in synchronization with a casting cycle of a die casting machine and using a ladle attached to the tip of the arm. The present invention relates to a swing arm type hot water supply device that pumps the molten metal into the injection sleeve automatically.

<Prior Art and Problems Thereof> Generally, in this type of swing arm type hot water supply apparatus, after the hot water supply to the injection sleeve is completed, the arm for tiltably supporting the ladle is swing-moved to the holding furnace side, and When the ladle is returned to and the molten metal is pumped up from the holding furnace, the detection signal (braking signal) is output from the molten metal level detector (electrode rod, etc.) that is installed in a state of protruding (drooping) from the tip of the arm. The ladle is immersed (immersed) in the molten metal in the holding furnace by lowering the arm to the moving limit, in other words, the lower moving limit where the melt level detector contacts the molten metal in the holding furnace. , The arm is moved up and the molten metal is drawn into the ladle.

However, since the conventional hot water supply device has the molten metal surface detector fixedly attached to the tip of the arm, the molten metal surface detector does not allow the arm to descend to the lower limit of movement so that the ladle is immersed in the molten metal in the holding furnace. From the time it takes to draw the molten metal into the ladle and move it upwardly, it is exposed to the high heat of the molten metal while it is in contact with the molten metal. As the oxide progresses, the oxide on the surface of the molten metal tends to adhere, and the oxide accumulates in an icicle shape, and the deposited oxide serves as a molten metal level detection contact and pumps the molten metal under regular molten metal level detection. I can't.

In other words, this kind of hot water supply device is one that quantitatively pumps the molten metal from the holding furnace for each casting cycle of the die-casting machine under preset quantitative control, and quantitatively pumps the molten metal pumped into the ladle into the injection sleeve. However, the fact that oxides adhere to and deposit on the molten metal detector in an icicle-like manner prevents normal molten metal surface detection because the lower limit position of the arm movement is displaced and the ladle is held in the molten metal in the holding furnace. The molten metal is not dipped to the proper position, so that the molten metal cannot be quantitatively pumped from the holding furnace, which also causes an insufficient situation in which the filling rate of the molten metal in the mold cavity becomes insufficient, resulting in defective products. There is danger.

Further, a bath level detector equipped in this type of hot water supply device energizes when two electrode rods are hung in parallel and both electrode rods simultaneously contact the bath surface, whereby a detection signal is sent to the hot water supply device. Since the mainstream is to output to the drive source (motor with brake, etc.) so as to brake the limit of the downward movement of the arm,
If the oxide adheres and accumulates in an icicle shape, an erroneous signal is output such that both electrode rods are energized by the oxide during swing movement of the arm or the like, causing a hot water supply problem.

<Problems to be Solved by the Invention> The present invention has been made in view of such conventional problems, and the technical problem to be solved is to make the contact time of the molten metal surface detector with the molten metal as long as possible. It should be short so that it does not receive the high heat (thermal shock) of the molten metal.
