[0054] refer to Figure 5 , Figure 7 and Figure 8 A limiting mechanism 7 is provided on the second adjusting block 53, and the limiting mechanism 7 includes a fixed block 71 fixedly connected to the second adjusting block 53, and a avoidance hole for the first bidirectional screw 572 to pass through is opened on the fixed block 71, and a placement groove 711 for placing the connecting pipe 24 is opened at one end of the fixed block 71 away from the second adjusting block 53; a limiting block 72 is slidably connected to the fixed block 71 to limit the connecting pipe 24 in the placement groove 711.

[0055] The fixing block 71 is provided with a sixth adjusting component 73, which includes a third rotating shaft 733 rotatably connected to the fixing block 71, one end of the third rotating shaft 733 is keyed to a third gear 7310, and a third rack 7311 meshing with the third gear 7310 is integrally provided on the limiting block 72; a second rotating shaft 732 is rotatably connected to the fixing block 71, one end of the second rotating shaft 732 close to the first rotating shaft 731 is keyed to a third bevel gear 738, and one end of the first rotating shaft 731 away from the third gear 7310 is keyed to a third rack 7311 meshing with the third gear 7310. The fourth bevel gear 739 is meshed with the three-bevel gear 738; the first rotating shaft 731 is rotatably connected to the second adjusting block 53, the end of the first rotating shaft 731 close to the second rotating shaft 732 is keyed to the first bevel gear 736, and the end of the second rotating shaft 732 away from the third bevel gear 738 is keyed to the second bevel gear 737 meshed with the first bevel gear 736; the end of the first rotating shaft 731 away from the first bevel gear 736 is keyed to the second gear 734, and the first adjusting block 52 is fixedly connected to the second rack 735 meshed with the second gear 734.

[0056] Because the fixed second rack 735 is meshed with the second gear 734, when the second adjusting block 53 moves, the second gear 734 will rotate, and the second gear 734 will drive the first rotating shaft 731 to rotate, the first bevel gear 736 on the first rotating shaft 731 drives the second bevel gear 737 to rotate, the second bevel gear 737 drives the second rotating shaft 732 to rotate, the third bevel gear 738 on the second rotating shaft 732 drives the fourth bevel gear 739 to rotate, the fourth bevel gear 739 drives the third rotating shaft 733 to rotate, the third rotating shaft 733 drives the third gear 7310 to rotate, the third gear 7310 drives the third rack 7311 to move, and the third rack 7311 will drive the limiting block 72 to move.

[0057] The implementation principle of an injection mold ejection mold in an embodiment of the present application is: first start the fourth motor 581 to make the two clamping blocks 54 clamp the rotating tube 33; then place the middle position of the connecting tube 24 in the placement groove 711 of the fixed block 71; then start the second motor 561 to make the second adjustment block 53 move in the direction away from the rotating tube 33, and the limiting block 72 will move on the fixed block 71 and limit the connecting tube 24 in the placement groove 711 of the fixed block 71.

[0058] Then the mounting block 51 is made to contact the ejection plate 11, and the fixing rod 82 is engaged with the fixing groove on the ejection plate 11. At this time, the connecting pipe 24 is located at a side of the required installation position.

[0059] The first motor 551 is started to move the first adjustment block 52 on the installation block 51; when the connecting tube 24 is aligned with the position to be installed, the second motor 561 is started to drive the second adjustment block 53 to move the connecting tube 24 to the position to be installed, that is, the connecting tube 24 is located between the transfer tube 31 on the ejection block 13 and the transfer tube 31 on the ejection plate 11. When the second adjustment block 53 moves, the limiting block 72 will also slide on the fixing block 71, so that the limiting block 72 no longer interferes with the connecting tube 24 located in the placement groove 711.

[0060] Then, the third motor 571 is started to make the two sliders 61 move in opposite directions, and the rotating tubes 33 at both ends of the connecting tube 24 will move in opposite directions, so that the rotating tube 33 at one end of the connecting tube 24 will conflict with the transfer tube 31 on the ejection block 13, and the rotating block at the other end of the connecting tube 24 will conflict with the transfer tube 31 on the ejection plate 11.

[0061] Then, the fifth motor 651 is started to move the fourth adjusting block 62 on the slider 61, and the fourth adjusting block 62 drives the fifth adjusting block 63 to move, and the two clamping blocks 54 on the fifth adjusting block 63 will drive the rotating tube 33 to rotate; when the rotating tube 33 rotates, the threaded hole 331 on the rotating tube 33 will be threadedly connected with the threaded sleeve 32 on the transfer tube 31, and the rotating tube 33 will be displaced relative to the transfer tube 31, and the fifth adjusting block 63 will move in the second groove 621 of the fourth adjusting block 62, and the second spring 64 will be deformed.

[0062] When the threaded hole 331 on the rotating tube 33 is threadedly connected with the threaded sleeve 32 on the transfer tube 31 for a certain distance, the fourth motor 581 and the fifth motor 651 are started first to make the two clamping blocks 54 move in opposite directions. The two clamping blocks 54 no longer clamp the rotating tube 33. At this time, the second spring 64 restores its elastic deformation to restore the fifth adjusting block 63 to its original position relative to the fourth adjusting block 62; the fifth motor 651 restores the fourth adjusting block 62 to its original position relative to the slider 61.

[0063] Then the fourth motor 581 is started again, so that the two clamping blocks 54 move toward each other, and the two clamping blocks 54 clamp the rotating tube 33 again; the fifth motor 651 is started again, so that the two clamping blocks 54 continue to drive the rotating tube 33 to rotate, until the rotating tube 33 is completely threadedly connected with the threaded sleeve 32 on the transfer tube 31. At this time, the end of the dredging block 46 away from the supporting block 45 contacts the blocking bead 43 and pushes the blocking bead 43 to move, so that the blocking bead 43 no longer blocks the water flow hole of the first blocking block 41, and the third connecting hole 461 on the dredging block 46 is connected with the first connecting hole 422 on the second blocking block 42.

[0064] The coolant in the water inlet pipe 21 enters the transfer pipe 31 connected to the water inlet pipe 21, then enters the connecting pipe 24, then enters the transfer pipe 31 connected to the connecting pipe 24, then enters the cooling pipe 23, then enters the transfer pipe 31 at the other end of the cooling pipe 23, then enters the connecting pipe 24, and finally flows back to the water outlet pipe 22 through the transfer pipe 31 connected to the water outlet pipe 22.

[0065] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
