After the metal solution cools and solidifies, the staff starts the hydraulic press 4 to drive the top cavity 71 to move upward. At this time, the upper die 73 and the bottom die 78 are separated and opened to facilitate the opening and closing of the mold during the casting process.

[0052] The staff rotates the rotating rod 824 to drive the extension plate 823 to rotate to a position connected with the base 75, and then the staff pushes the dumbbell short iron bar so that the dumbbell short iron bar slides on the surface of the extension plate 823 and generates friction with the guide roller 822, so that the guide roller 822 rotates to improve the material guiding efficiency and guide and transport the dumbbell short iron bar.

[0053] The staff transports the molten metal into the casting cavity 6 through the liquid guide port 10. Since the casting cavity 6 is connected to the top cavity 71, the molten metal is transported along the top cavity 71 to the injection groove 72. At this time, the injection groove 72 fits with the molding groove 76 at the bottom, so that the molten metal fills the injection groove 72 and the molding groove 76. After cooling and molding, the dumbbell is cast. Since part of the molten metal will overflow from the gap between the upper die 73 and the bottom die 78 during casting, the staff starts the hydraulic press 4 at this time, so that the hydraulic press 4 moves downward again so that the cutting knife 96 and the inclined sheet 95 installed on the outer side of the upper die 73 clean the excess edge after the overflow cooling and molding, so as to trim the edge of the dumbbell casting to prevent the excess edge from adhering to the mold surface after solidification and affecting the opening and closing of the mold.
