Multiple groups of water baffles 6 and water transport rings 7 form a circulation path with a serpentine structure. During the injection molding process of the injection molding machine, the molten injection plastic will pass through the gate sleeve body 1, causing the temperature of the gate sleeve body 1 to rise. By injecting cooling water from a group of cooling water channels 12 into the water transport ring 7 and the water baffle 6, the gate sleeve body 1 is heat-absorbed and cooled. The cooling water that absorbs heat is discharged through another group of cooling water channels 12, thereby achieving rapid cooling of the gate sleeve body 1, improving the heat dissipation effect of the gate sleeve, and extending the service life of the gate sleeve. At the same time, the water transport ring 7 is opened on the bottom surface of the sealing plate 2, and the water baffle 6 and the cooling water channel 12 are vertical and horizontal through grooves, which can be directly processed by lathes and drilling machines, reducing the tediousness of traditional multi-angle drilling, making the processing technology of the gate sleeve simple and convenient.

[0026] Example 2:

[0027] See also Figure 1-6 In this embodiment, sliding grooves 11 matching the baffle 6 are symmetrically opened on both sides of the inner part of the sprue sleeve body 1 near the water guide groove 8, and the baffle 6 slides inside the sliding groove 11, and an arc-shaped water groove is opened at the bottom end of the baffle 6. A threaded groove with an arc structure is symmetrically opened on one side of the inner part of the sprue sleeve body 1 near the top of the water guide groove 8, and the threaded column 5 is screwed to the inner part of the sprue sleeve body 1 through this threaded groove. The top of the sealing block 4 is fixedly connected to the rotating part 3, and an insertion groove is opened on the side of the sealing plate 2 near the rotating part 3. The cross-sections of the sealing block 4 and the water transport ring 7 are both trapezoidal structures, and the cross-section of the water transport ring 7 matches the bottom end of the cross-section of the sealing block 4. The sliding groove 11 is convenient for moving the water guide ring 7. The interior of the groove 8 is divided and matched with the arc groove at the bottom end of the water baffle 6, so that the cooling water can flow in a serpentine shape, so that the cooling water is in full contact with the gate sleeve body 1, further improving the cooling effect of the gate sleeve body 1, the threaded column 5 is screwed into the inside of the gate sleeve body 1, and the water baffle 6 can be disassembled by rotating the rotating part 3 to separate the sealing plate 2 from the gate sleeve body 1, which is convenient for cleaning the inside of the water guide groove 8 when the water guide groove 8 is blocked. The sealing effect of the rotating part 3 after installation can be improved by the sealing block 4, and the cross-sections of the sealing block 4 and the water transport ring 7 are both trapezoidal, which improves the blocking effect of the sealing block 4 on the water flow inside the water transport ring 7, and facilitates the water flow to fully flow inside the gate sleeve body 1;

Then, cooling water is injected into the circulation passage through the cooling water channel 12 on one side to achieve cooling of the gate sleeve body 1, and the cooling effect is good, thereby improving the service life of the gate sleeve. At the same time, the water transport ring 7 is opened on the bottom surface of the sealing plate 2, and the water baffle 6 and the cooling water channel 12 are vertical and horizontal through grooves inside the gate sleeve body 1, which can be directly processed by lathes and drilling machines, avoiding the tedious traditional multi-angle drilling, making the processing technology of the gate sleeve simple and convenient.
