[0072] In this embodiment: after pouring is completed, the upper mold 4 moves toward the side away from the lower mold 21 through the connecting rod 5. During the movement, the upper mold 4 drives the insertion rod 25 to move synchronously. When the insertion rod 25 no longer resists the elastically set second limit plate 26, under the action of the first elastic member 28, the first airbag 27 contracts, and the gas inside the first airbag 27 is discharged to the inside of the second airbag 32 through the first exhaust hole 29.

The internal gas of the sixth airbag 58 will be discharged to the interior of the third airbag 40 through the second exhaust pipe 38. The third airbag 40 will expand and be inserted into the sealing groove 39, thereby sealing the connection between the push plate 23 and the lower mold 21.

[0078] Specifically, such as Figure 3 and Figure 7 As shown, a metal bellows compensator casting mold also includes a grinding assembly for grinding the cast metal bellows compensator, the grinding assembly includes a curved plate 14 rotatably arranged inside the processing table 3, and the curved plate 14 is connected to a side wall of the cast metal bellows compensator on one side.

[0080] A rotation groove 41 is formed at the center of the inner wall of the guide ring 13. A gear 42 is rotatably provided inside the rotation groove 41. A second motor 15 is provided on the outer surface of the guide ring 13 at a position corresponding to the gear 42. The output end of the second motor 15 meshes with the gear 42.

[0081] The arc plate 14 is connected to the inner wall of the gear 42, and the arc plate 14 has an arc-shaped structure;

[0082] In this embodiment: the arc-shaped plate 14 drives the flexible grinding plate 48 to rotate through the cooperation of the gear 42 and the second motor 15;

[0083] Specifically, such as Figure 3 and Figure 7 As shown, the inner wall of the curved plate 14 is provided with a plurality of first countersunk holes 43 spaced apart from each other.

[0090] In this embodiment: through the cooperation of the first motor 7 and the first transmission screw 8, the guide block 20 is driven to move along the guide groove 6, and then the automatic telescopic cylinder 9 is driven to move relative to the processing table 3. During the movement, the automatic telescopic cylinder 9 drives the first limit plate 10 to move. After the grinding is completed, the first limit plate 10 is moved to the bottom of the grinding device. At this time, when the arc plate 14 drives the elastically arranged extension rod 45 to rotate, with the cooperation of the end of the first limit plate 10, all groups of extension rods 45 are compressed to the bottom of the first limit plate 10, making it convenient for the next group of metal bellows compensators to be ejected.

[0094] The clamping assembly further includes a first limit block 11 provided on the upper end surface of the upper mold 4. A third receiving groove 49 is formed on the inner side wall of the processing table 3 at a position corresponding to the first limit block 11. A first ejector rod 12 is provided inside the third receiving groove 49. The cross section of the first ejector rod 12 is an "L"-shaped structure.

During the movement, the first limit block 11 will gradually no longer limit the elastically set first push rod 12. At this time, the first push rod 12 squeezes the third receiving groove 49 under the action of the sixth elastic member 51, and the gas inside the third receiving groove 49 is discharged to the inside of the air storage chamber 56 through the third exhaust pipe 52. The gas inside the air storage chamber 56 is then discharged to the inside of each fifth air bag 54 through the fourth exhaust pipe 57. Each fifth air bag 54 expands and pushes the corresponding clamping rod 17 outward. Each clamping rod 17 can clamp the metal bellows compensator ejected from the lower mold 21 to facilitate grinding.

[0099] Specifically, the present solution is as follows: the upper mold 4 is driven to move toward the lower mold 21 by the cooperation of the connecting rod 5 and the driving device, so that the cavities in the upper mold 4 and the lower mold 21 form a metal bellows-type compensator. Then, the pouring material in the pouring machine is discharged into the cavity formed by the upper mold 4 and the lower mold 21 by the cooperation of the injection tube 18. After the discharge is completed, the material is allowed to cool. After the cooling is completed, the upper mold 4 is driven to move away from the lower mold 21 again by the cooperation of the connecting rod 5 and the driving device.

[0100] After the pouring is completed, the upper mold 4 moves toward the side away from the lower mold 21 through the connecting rod 5. During the movement, the upper mold 4 drives the insertion rod 25 to move synchronously. When the insertion rod 25 no longer resists the elastically set second limit plate 26, under the action of the first elastic member 28, the first air bag 27 contracts, and the gas inside the first air bag 27 is discharged to the inside of the second air bag 32 through the first exhaust hole 29. The second air bag 32 expands and pushes out the second push rod 30. The second push rod 30 pushes the push plate 23 to extend, thereby ejecting the finished metal bellows compensator after pouring. At the same time, after the pouring is completed, the upper mold 4 By moving the connecting rod 5 toward the side away from the lower mold 21, the first limit block 11 will gradually stop limiting the elastically provided first ejector rod 12 during the movement. At this time, the first ejector rod 12 squeezes the third receiving groove 49 under the action of the sixth elastic member 51. The gas inside the third receiving groove 49 is discharged into the interior of the gas storage chamber 56 through the third exhaust pipe 52. The gas inside the gas storage chamber 56 is then discharged into the interior of each fifth airbag 54 through the fourth exhaust pipe 57. Each fifth airbag 54 expands and pushes the corresponding clamping rod 17 outward. Each clamping rod 17 can clamp the metal bellows-type compensator ejected from the lower mold 21.

[0101] After clamping, start the first transmission screw 8, and the first transmission screw 8 drives the first motor 7 to rotate, and then drives the first limit plate 10 to move through the guide block 20. When the first limit plate 10 no longer limits the elastically set extension rod 45, the flexible grinding plate 48 will contact the surface of the metal bellows compensator. At this time, start the second motor 15, and through the cooperation of the gears, drive the arc plate 14 to rotate around the metal bellows compensator. During the rotation process, the elastically set extension rod 45 presses the flexible grinding plate 48 to always be close to the surface of the metal bellows compensator, thereby realizing the grinding of the fold position of the metal bellows compensator.
