[0002] Waste copper is a very important recycling resource, which can be used to manufacture marine valve bodies. When using waste copper to manufacture marine valve bodies, intelligent casting islands are usually used for casting. An intelligent casting island is an automatic working platform with intelligent production functions. It usually includes multiple casting devices and an automation system for performing a series of casting processes from mold preparation, material melting, casting, cooling to demolding. By integrating Internet of Things, artificial intelligence, robotics, etc., the intelligent casting island can achieve an efficient, accurate and automated production process.

[0037] like Figure 4 , Figure 8 and Figure 9As shown, both ends of the connecting carrier plate 54 are symmetrically hinged with movable connecting plate strips 55, and the other end of the movable connecting plate strip 55 is hinged with a supporting carrier sleeve 6, that is, the other end of the movable connecting plate strip 55 is hinged with the mounting carrier plate 61. A downward extending bearing plate 56 is fixedly arranged at the lower end of the connecting carrier plate 54, a connecting bottom frame 57 is fixedly arranged at the lower end of the downward extending bearing plate 56, a first limiting insertion plate 58 is fixedly arranged at one end of the connecting bottom frame 57 away from the downward extending bearing plate 56, and side connecting plate strips 59 are symmetrically and fixedly arranged on both sides of the connecting bottom frame 57. A driving connecting plate strip 591 is hinged on the side connecting plate strip 59.

[0038] As Figure 3 and Figure 4 shown, the auxiliary fixing component is a locking carrier plate 7. The locking carrier plate 7 is hinged with the driving connecting plate strip 591, and a matching insertion rod 71 is fixedly arranged on the locking carrier plate 7; The matching insertion rod 71 is inserted into the moving guide hole 18, and a movable bearing plate 72 is fixedly arranged on the matching insertion rod 71. A second limiting insertion plate 73 is fixedly arranged on the movable bearing plate 72. A first limiting cavity 91 is opened at one end of the lower mold 9, and second limiting cavities 92 are symmetrically opened on both sides of the lower mold 9.

[0039] In addition, the cavities of the upper mold 8 and the lower mold 9 are set according to actual use requirements.

[0040] A casting process includes the following steps: Step 1: Positioning of the molds: The upper mold 8 to be used is inserted into the supporting carrier sleeve 6 for positioning, and the lower mold 9 to be used is inserted into the limiting ring plate 16 for positioning; Step 2: Selection of the molds: Push the bearing connecting plate 3 towards the direction of the mold to be used, so that the bearing connecting column 32 is connected to the upper mold 8 to be used; Step 3: Fixing of the lower mold 9: The fixing of the lower mold 9 to be used is realized as the bearing connecting plate 3 moves; Step 4: Closing the mold: Start the electric telescopic rod 2 to drive the upper mold 8 to move downward to close with the lower mold 9; Step 5: Pouring: Pour the molten copper liquid into the mold; Step 6: Opening the mold: After the valve body is formed, open the mold to take out the valve body.

[0041] When casting the valve body, select appropriate molds and install them at both ends of the casting island table 1, that is, one set of upper and lower molds at each end. The upper mold 8 is inserted into the support carrier sleeve 6 for positioning, and the lower mold 9 is positioned by the limit ring plate 16. When inserting the upper mold 8, insert the connecting link plate 88 into the connecting chute 51, and the connecting link plate 88 is in contact with the inner wall of the connecting chute 51. Select the mold according to the usage requirements, that is, push the load-bearing connecting plate 3 towards the end where the mold to be used is located. When pushing the load-bearing connecting plate 3, the load-bearing connecting column 32 will be inserted into the connecting channel 84. As the load-bearing connecting column 32 is inserted, it will push the mating connecting column 87 to move. As the mating connecting column 87 moves, under the action of the connecting link plate 88, it will drive the U-shaped plate frame 5 to move. In this way, under the action of the movable connecting plate strip 55, it will push the support carrier sleeve 6 connected to it to move away from each other, so that it no longer supports the upper mold 8, which facilitates the up and down movement of the upper mold 8. When the U-shaped plate frame 5 moves, it will drive the first limit insertion plate 58 to be inserted into the first limit cavity 91. And as the U-shaped plate frame 5 moves, under the action of the driving connecting plate strip 591, it will drive the locking carrier plate 7 to move, so that the second limit insertion plate 73 on the locking carrier plate 7 is inserted into the second limit cavity 92 to fix the lower mold 9. When the load-bearing connecting plate 3 moves, the contact runner 47 will cross the limit clamping plate 22. In this way, under the action of the connecting spring 44, the load-bearing strip plate 43 will move, so that the limit carrier 46 is stuck at the end face of the limit clamping plate 22 to limit the load-bearing connecting plate 3 so that it cannot move in the reverse direction, ensuring the connection between the load-bearing connecting column 32 and the upper mold 8. In this way, the upper mold 8 can be driven to move down for casting. When it is necessary to change the mold, the load-bearing support table 21 moves up and resets, and then push the movable carrier plate 4 so that the limit carrier 46 is no longer restricted by the limit clamping plate 22. Then the load-bearing connecting plate 3 can be moved to the other end to be connected to another upper mold 8, so as to realize the conversion of the mold. At the same time, the previous upper mold 8 and lower mold 9 are unlocked as the load-bearing connecting plate 3 is removed. If there is a need to replace the mold, it can be replaced during casting without affecting the next casting, which is very convenient.

[0042] Although the embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made in these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
