[0028] Compared with the prior art, the beneficial effects of the present invention are as follows: the ductile iron casting equipment capable of evacuating bubbles is symmetrically provided with a defoaming assembly above the base, so that the ductile iron can be cooled during casting, and the gas solubility in the metal liquid can be reduced, thereby prompting the gas to precipitate and be discharged from the metal liquid, and the mold can be knocked during cooling to cause the mold to vibrate slightly, and the vibration can change the pressure distribution inside the molten iron, so that the gas is more easily released from the metal liquid, so that the ductile iron is defoamed during casting, thereby avoiding affecting the production quality of the ductile iron;

[0029] 1. A defoaming assembly is symmetrically arranged above the base. When casting ductile iron, the mold is placed on the top of the placing table, and the fixed plate is driven to move by the hydraulic push rod so that the height of the casting bucket between the lifting plates can be adjusted. The casting bucket is driven to rotate by the rotating motor to add metal liquid to the mold. The driving motors on the two movable plates are started to drive the rotating shaft to rotate, so that the rotating blades rotate to cool the ductile iron. While the rotating shaft rotates, the meshing of the first bevel gear and the second bevel gear drives the rotating rod to rotate between the fixed blocks, so that the two protrusions on one side of the rotating rod rotate. After the protrusions rotate, the connecting plate can be pushed to move, so that the connecting plate drives the movable rod to move, and the movement of the movable rod can press The telescopic spring can push the sliding rod to slide on the rotating sleeve after the movable rod moves, driving the rotating sleeve to rotate, and then driving the striking block to move. After the protrusion is no longer in contact with the connecting plate, the telescopic spring drives the movable rod to reset, so that the striking block can be reset to knock on the mold. The defoaming component can be used to cool the ductile iron during casting, which can reduce the solubility of gas in the metal liquid, thereby causing the gas to precipitate and discharge from the metal liquid. The mold can be knocked while cooling, causing the mold to vibrate slightly. The vibration can change the pressure distribution inside the molten iron, making it easier for the gas to be released from the metal liquid, so that the ductile iron can be defoamed during casting to avoid affecting the production quality of the ductile iron.

[0030] 2. When the rotating shaft rotates, the first pulley and the second pulley cooperate to drive the connecting shaft to rotate. The connecting shaft can drive the reciprocating screw to rotate between the positioning blocks through the cooperation of the third bevel gear and the fourth bevel gear, so that the connecting sleeve drives the movable plate to move back and forth. When the movable plate moves, the T-shaped block slides inside the T-shaped groove to limit the movement of the movable plate, so that the movable plate can move back and forth while the mold is being cooled and knocked, thereby expanding the cooling and knocking range, improving the defoaming efficiency, avoiding repeated knocking on the same position of the mold, and improving practicality;

[0031] 3. When adjusting the defoaming range, the connecting rod is driven to move by the electric push rod, so that the movable plate can be driven to move through the mounting frame and the sliding sleeve, so that the height of the defoaming component can be changed, the cooling and knocking range can be further improved, and the defoaming efficiency is improved. When casting ductile iron, the mold is placed on the top of the placement table, and the threaded rod is driven to rotate by turning the hand wheel. The rotation of the threaded rod can drive the movable plate to move through the connection with the cross plate, so that the sliding sleeve slides on the guide rod, and then the distance between the two defoaming components can be adjusted, so that the knocking block can fit with both sides of different molds, so as to facilitate the use of different molds and improve the applicability.
