[0032] The working principle of the injection mold with adjustable number of heat dissipation channels provided by the utility model is as follows:

[0033] Step 1: When in use, the screw rod 8 can be rotated by rotating the rotating block 9, and the screw rod 8 can be moved upward along the upper mold 1. At this time, the sealing block 7 can be driven to slide inside the slide groove 6. When the slide groove 6 is at the bottom, the corresponding water hole 5 can be sealed. When the slide groove 6 is at the top, the corresponding water hole 5 is connected to the through groove 4. By adjusting the position of the sealing block 7, it can be controlled whether there is coolant flowing into the corresponding water hole 5. After adjusting the sealing block 7, the coolant pipe is connected to the water inlet 3.

At this time, the sealing block 7 can be driven to slide inside the chute 6. When the chute 6 is at the bottom, the corresponding water hole 5 can be sealed. When the chute 6 is at the top, the corresponding water hole 5 is connected to the through groove 4. By adjusting the position of the sealing block 7, it can be controlled whether there is coolant flowing into the corresponding water hole 5. After adjusting the sealing block 7, the coolant pipe is connected to the water inlet 3. The coolant enters the through groove 4 from the water inlet 3, is dispersed into the water hole 5 from the through groove 4, and then passes through the first connecting hole 10 and the second connecting hole 11 to enter the cooling pipe hole inside the lower mold 2. , and finally flows out from the water outlet 12. The number of heat dissipation channels can be adjusted through this structure, and the heat dissipation efficiency can be adjusted according to needs. After the upper mold 1 and the lower mold 2 are docked, the sliding ring 24 is squeezed to make the sliding ring 24 close to the limit plate 23. At this time, the sliding ring 24 squeezes the spring 25, and then the rotating rod 21 is rotated to make the vertical rod 22 stuck into the inner side of the limit block 20. At this time, the sliding ring 24 is released, and the elastic force of the spring 25 can make the sliding ring 24 and the limit block 20 close together. At this time, the elastic force of the spring 25 can make the limit plate 23 pull the vertical rod 22 downward, so that the upper mold 1 and the lower mold 2 are close together. This structure can facilitate the close contact between the upper mold 1 and the lower mold 2.
