本発明は、鋳造凝固した金地金を鋳型から離型する方法
に関する。DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a method for releasing a cast solidified gold ingot from a mold.
(従来の技術)
従来、鋳造凝固した金地金を鋳型から離型するには、作
業員が1個づつ金地金を鋳型から離型していた。(Prior Art) Conventionally, in order to release a cast solidified gold bullion from a mold, a worker had to release the gold bullion one by one from the mold.
しかし、この方法は作業能率が悪いので、機械化による
離型方法として、モールドに鋳造され固化した金地金を

ところで、上記反転方式による離型は、金地金を水槽に

、乾燥によりウォータマークが外面に残り、商品価値が
低下するという問題があった。However, this method has poor work efficiency, so a mechanized mold release method involves inverting the solidified gold that has been cast into a mold by inverting the mold using an ejector cylinder, releasing the gold from the mold, and dropping it into a water tank. There is a method. (Japanese Unexamined Patent Publication No. 1-239384 is a prior art document.) (Problems to be Solved by the Invention) By the way, in the above-mentioned mold release using the inversion method, the gold bullion is dropped into a water tank, so the gold bullion is removed from the water. The removal work and the subsequent drying process impede the streamlining of the entire gold bullion manufacturing process, and if water droplets adhere to the surface of the gold bullion, water marks will remain on the outer surface due to drying, reducing the product value. was there.
一方、金地金は鋳型に鋳込んだ上面が金地金表面となる
為、水槽に落下させない反転方式では金地金の表面に傷
が付き易(、且つその後の工程が高温状態の金地金を取
扱う工程となる為、自動化しにくいものである。On the other hand, since the top surface of the gold bullion that is cast into the mold becomes the gold bullion surface, the surface of the gold bullion is easily scratched by the inversion method that does not drop the gold bullion into a water tank (and the subsequent process is a process in which the gold bullion is handled at a high temperature). Therefore, it is difficult to automate.
そこで本発明は、鋳型を反転させることな(鋳型内の鋳

鋳造金地金の離型方法を提供しようとするものである。SUMMARY OF THE INVENTION Therefore, the present invention provides a method for releasing a cast gold ingot, in which the solidified gold in the mold is released and dropped with the cast surface facing down, without inverting the mold.

Next, the mold is moved above the cooling device by the robot's special hand, and then tilted so that the front side of the mold faces downward.Then, the special hand moves the mold up and down at high speed to remove the gold in the mold. At the same time as the mold is released, the special hand is moved backwards to tilt the mold back and catch the falling gold bullion with the front half of the mold, and then rotate it downward to place the mold in the cooling device. The method is characterized by lowering the metal to a specified position in the cooling device, then moving the mold up and down at high speed using a special hand, and then immediately retracting the mold to place the gold bullion, casting surface facing down, in a predetermined position in the cooling device. .

することが無い。(Function) As described above, the method for releasing a cast gold bullion according to the present invention involves tilting the mold containing the cast solidified gold bullion downward at a predetermined position of the cooling device using a special hand of a robot without reversing the mold. The gold bullion is removed from the mold by moving up and down at high speed and placed on the cooling device with the casting surface facing down, so the casting surface, which is the surface of the gold bullion, is easily damaged by falling. There is no such occurrence. In addition, the drop point can be lowered, so when placed on a cooling device, the impact is small, and the cast surface prevents scratches (also, unlike conventional methods, when it is dropped upside down into an aquarium). Since the removal work from water and the subsequent drying process are no longer necessary, the gold bullion manufacturing process is streamlined, and there is no water droplet adhesion to the outer surface of the gold bullion or water marks left due to drying, which reduces the product value. None.

The handle part 3 of the robot is gripped by the special hand 4 of the robot as shown in FIG. 2g, and then the special hand 4 of the robot is operated,
After moving the mold l above the cooling device 5 as shown in Fig. 2C, the front of the mold l is tilted downward, and then the dedicated hand 4 is operated to move the mold l as shown in Fig. 2C. 1 by moving up and down at high speed (as shown in Figure 2g) (the gold bullion 2 in the mold 1 is released into the air, and at the same time, the special hand 4 is moved backward to move the mold 1 backward in an inclined state and release the first half of the mold 1). (Catch the metal ingot 2 as shown in Figure 2e,
Next, operate the special hand 4 in that state and mold the mold l.
2. Rotate the mold 1 downward and lower it to the predetermined position of the cooling device 5 as shown in FIG. As shown in the figure, the mold 1 was moved back and the gold bullion 2 was placed in a predetermined position on the cooling device 5 with the casting surface 2a facing down.The gold bullion 2 was transferred to the next process while being cooled by the cooling device 5. .

が低下することが無い。As described above, the method for releasing the cast gold bullion according to the embodiment involves not inverting the mold l containing the cast and solidified gold bullion 2 using the dedicated hand 4 of the robot (i.e., placing the mold l containing the solidified gold bullion 2 under the predetermined position of the cooling device 5). It is tilted, moved up and down at high speed and retreated, and the gold bullion 2 is released from the mold l and placed on the cooling device 5 with the casting surface 2a facing down, which becomes the surface of the gold bullion 2. The casting surface 2b does not suffer any damage due to falling.Furthermore, since it is placed quietly on the cooling device, there is almost no impact.
The casting surface 2a is also less likely to be scratched. In addition, the gold bullion manufacturing process is streamlined because the conventional process of removing the gold bullion by inverting it into a water tank and the subsequent drying process is no longer required. ,
There is no remaining water mark due to drying, and the product value does not decrease.
