[0022] A specific application of the above embodiment is: firstly, the hydraulic cylinder 3 is started to pull the positioning frame 4, so that the upper mold body 5 moves downward and is assembled with the lower mold body 2, and then the aluminum alloy fluid is injected into the cavity between the lower mold body 2 and the upper mold body 5 to form the aluminum alloy part in the cavity; After the aluminum alloy part is cooled, the hydraulic cylinder 3 is started to push the upper mold body 5 to move upward. During the rising process of the upper mold body 5, the traction rope 48 can be pulled synchronously. Since the traction rope 48 is located between the guide seat 47 and the displacement seat 45, the displacement seat 45 can be driven to move under the limit of the linear slide rod 44, and the spiral spring 46 is squeezed, and the connection between the displacement seat 45 and the transmission rack 50 is matched. When the transmission rack 50 passes through the guide spur gear 11, the guide spur gear 11 can be moved to cause the guide shaft 10 to rotate, and the connection between the guide spur gear 11 and the conduction screw 12 can be matched to drive the conduction screw 12 to move vertically, change the height of the adjustment plate 13, and move the ejection rod 15 into the cavity to eject the formed aluminum alloy part for easy access by personnel; After the aluminum alloy part is removed, the hydraulic rod 51 is then started to pull the stop block 52 out of the locking hole, and the hydraulic cylinder 3 is continued to be started to push the upper mold body 5 up, causing the transmission rack 50 to disengage from the guide spur gear 11, and pass through the transmission spur gear 18, and then move the transmission spur gear 18, causing the support shaft 17 to rotate. Under the connection between the support shaft 17 and the assembly frame 19, the assembly frame 19 can be driven to rotate, and the air flow nozzle 20 is adjusted to the top of the cavity of the lower mold body 2. After adjustment, the hydraulic rod 51 is started to cause the stop block 52 to be stuck in the locking hole, forming a rotation lock of the support shaft 17, and The central shaft 21 is started to drive the central shaft 21 to rotate, and the eccentric transmission plate 23 is connected to the central shaft 21, so that the eccentric transmission plate 23 rotates with the central shaft 21, and moves adaptively inside the travel slot 25, thereby pushing the eccentric linkage plate 24. Since the eccentric linkage plate 24 is supported by the airflow nozzle 20, it can drive the airflow nozzle 20 to rotate, and change the air outlet direction of the airflow nozzle 20. Since the eccentric transmission plate 23 rotates in a circle, when the eccentric transmission plate 23 rotates one circle, the airflow nozzle 20 will return to the initial displacement, thereby reducing the operation blind area of ​​the airflow nozzle 20; In the process of the central shaft 21 rotating, the transmission bevel gear 29 can be used to shift the matching bevel gear 30, thereby driving the linkage shaft 28 to rotate, and the acceleration spur gear 33 can be shifted by the linkage spur gear 31, so as to cause the wind-making shaft 32 to rotate. Under the connection between the wind-making shaft 32 and the wind-making disk 34, the wind-making disk 34 can introduce the external airflow into the wind-making cylinder 26. Before the airflow enters the wind-making cylinder 26, the filter plate 36 can be used to filter the impurities in the airflow. The airflow entering the wind-making cylinder 26 will be transmitted to the airflow nozzle 20 through the transmission pipe 27, and finally ejected through the airflow nozzle 20 to blow out the impurities in the cavity of the lower mold body 2. When the application effect of the filter plate 36 is not good, the transmission screw 40 is rotated to cooperate with the connection between the transmission screw 40 and the displacement push plate 41, so that the displacement push plate 41 can be displaced along the displacement push plate 41, and because the push guide plate 42 is connected between the displacement push plate 41 and the limit plate 39, when the displacement push plate 41 is displaced, the push guide plate 42 can be used to push the limit plate 39, so that it rotates under the support of the carrying shaft 38. When the limit plate 39 is moved out from above the wind tube 26, the obstruction to the filter plate 36 can be released, and then it can be removed from the inside of the wind tube 26 for replacement; When the upper mold body 5 descends, the rebound of the coil spring 46 can be used to push the transmission rack 50 to pass through the transmission spur gear 18 and the guide spur gear 11 in sequence, and then drive the air flow nozzle 20 and the ejection rod 15 to return to the initial position.
