[0035] As attached Figure 4 As shown, connecting blocks 10 are fixedly connected to both sides of the lower mold housing 3. One of the connecting blocks 10 has a threaded hole 11 inside, and the other connecting block 10 has a through hole 12 inside. The threaded hole 11 matches the thread of the lead screw 14.

[0036] As attached Figure 1As shown, fixed shells 13 are fixedly connected to both sides of the lower mold housing 3. A lead screw 14 is rotatably connected inside one of the fixed shells 13, and a limit rod 15 is fixedly connected inside the other fixed shell 13. One connecting block 10 is threaded to the outside of the lead screw 14 through a threaded hole 11, and the other connecting block 10 is slidably connected to the outside of the limit rod 15 through a through hole 12. A first bevel gear 16 is fixedly connected to one end of the lead screw 14. A fixed plate 17 is fixedly connected to the upper surface of one of the fixed shells 13. A second bevel gear 18 is rotatably connected to one side of the fixed plate 17. The first bevel gear 16 and the second bevel gear 18 are meshed. A throttle 19 is fixedly connected to the middle of the second bevel gear 18. When the limit rod 15 is connected to one of the connecting blocks 10, it is convenient to limit the upward movement of the lower mold housing 3. The throttle 19 is convenient to drive the lead screw 14 to rotate through the first bevel gear 16 and the second bevel gear 18.

[0037] As attached Figure 3 As shown, a sealing assembly is provided on the upper surface of the lower mold inner shell 1. The sealing assembly includes a first mounting groove 20, which is opened on the upper surface of the lower mold inner shell 1. A second mounting groove 22 is opened at the outer bottom end of the lower mold inner shell 1, which are used to install the first sealing bottom ring 21 and the second sealing bottom ring 23, respectively.

[0038] As attached Figure 2 As shown, a first sealing bottom ring 21 is provided inside the first mounting groove 20, and a second sealing bottom ring 23 is provided inside the second mounting groove 22, which are respectively connected to the first sealing top ring 24 and the second sealing top ring 25.

[0039] As attached Figure 4 As shown, a first sealing ring 24 is provided on the top of the inner wall of the lower mold inner shell 1 to facilitate sealing the upper surface of the lower mold inner shell 1, and a second sealing ring 25 is provided on the lower surface of the lower mold outer shell 3 to facilitate sealing the bottom of the lower mold inner shell 1.

[0040] As attached Figure 7 As shown, a spiral sealing ring 26 is provided on the outside of the lower mold inner shell 1.

[0041] Working principle: In use, open the threaded cap 9 at one end of the water inlet pipe 7 and the water outlet pipe 8, and then connect a water pipe to the water inlet pipe 7 and the water outlet pipe 8. The coolant enters through the water inlet pipe 7, allowing the coolant to flow into the water channel formed by the inner spiral water channel 4 and the outer spiral water channel 5. The coolant exits through the water outlet pipe 8 and is then exchanged through the external water channel, thereby increasing the cooling efficiency of the lower mold inner shell 1. When it is necessary to clean the inner walls of the inner spiral water channel 4 and the outer spiral water channel 5, turn the handle 19 to drive the second bevel gear 18 to rotate. When gear 18 meshes with the first bevel gear 16, it drives the first bevel gear 16 to rotate, which in turn drives the lead screw 14 to rotate. Under the action of the threaded hole 11, the lead screw 14 drives the corresponding connecting block 10 to rise, which in turn causes the connecting block 10 to move the lower mold shell 3 upward. At this time, the lower mold shell 3 simultaneously drives the connecting block 10 on the other side to slide outside the limiting rod 15, so that the lower mold shell 3 and the lower mold inner shell 1 are separated, the inner spiral water tank 4 and the outer spiral water tank 5 are separated, and the inner wall is exposed, which facilitates the cleaning and maintenance of the inner wall of the water tank.

[0042] When the lower mold outer shell 3 merges with the lower mold inner shell 1 under the action of the connecting block 10, the first sealing top ring 24 will be inserted into the inside of the first sealing bottom ring 21, and the second sealing top ring 25 will be inserted into the inside of the second sealing bottom ring 23. At this time, the spiral sealing ring 26 will be tightly attached to the inner wall of the lower mold outer shell 3, so that the inner spiral water groove 4 and the outer spiral water groove 5 are sealed and joined together to form a water channel, which facilitates the flow and transportation of coolant.

[0043] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
