One end of the second sliding groove close to the blocking block penetrates through the protection plate. A second inclined surface matching the first inclined surface is formed on the side surface of the lifting plate facing the blocking block. When the protection plate is in the closed state, the first inclined surface and the second inclined surface are in mutual contact, and the fan is located above the second sliding groove.

[0015] By adopting the above technical solution, when the protection plate blocks the operation port and is in the closed state, the blocking block will abut against the lifting plate. Under the action of the first inclined surface and the second inclined surface, the lifting plate is driven to rise. At this time, the fan rises above the protection plate, and the fan starts to blow the hot steam generated after the water cooling of the die-casting machine away from the operation port side; when the protection plate moves to the open state towards the side away from the operation port, the blocking block gradually disengages from the lifting plate, and the lifting plate moves downward under the action of gravity, and the fan retracts into the second sliding groove, which can protect the fan when it is not in use.

[0016] Preferably, the third driving member includes a spring and a bolt. The spring is located below the corresponding fan. The two ends of the spring respectively abut against the fan and the bottom wall of the movable groove. A threaded groove is vertically formed in the bottom wall of the movable groove. The bolt is threadedly connected in the threaded groove, and the bottom end of the bolt abuts against the fan. The spring is used to drive the fan to always move upward.

[0017] By adopting the above technical solution, the operator can adjust the height position of the bottom of the bolt by screwing the bolt, and adjust the height position of the fan in cooperation with the spring, which can adapt to different die-casting machines.

[0018] Preferably, a groove is formed in the bottom wall of the movable groove, and the end of the spring away from the fan abuts against the bottom wall of the groove.

[0019] By adopting the above technical solution, the groove can improve the stability of the spring and increase the moving distance of the fan at the same time.

[0020] The technical effects of the present utility model are mainly reflected in the following aspects:

[0021] 1. By arranging the surrounding baffle in the present utility model, the surrounding baffle can protect the whole body of the die-casting machine. When the protection plate is moved away from the operation port, the operator or the manipulator can perform the blanking operation on the die-casting machine from the operation port. When the die-casting machine is performing die-casting operations, the protection plate moves to face the operation port, which can block the splashing of molten metal during die-casting, thereby improving the safety during the operation of the die-casting machine;

[0022] 2. By providing a blowing device in the present utility model, after the die-casting machine discharges materials, cooling water mixed with a mold release agent is used to cool the surface of the die-casting mold.
