Description

Technical Field

[0001] This utility model relates to the field of mold technology, and in particular to a mold cooling water channel structure. Background Technology

[0002] In the field of mold manufacturing and application, the mold cooling water structure plays a crucial role in controlling mold temperature, ensuring product molding quality, and improving production efficiency. Existing mold cooling water structure designs mostly employ the method of directly drilling cooling channels inside the mold to construct the cooling circulation system. During mold operation, a significant temperature difference exists between the high-temperature mold environment and the circulating cooling water. This frequent thermal expansion and contraction cycle acts on the mold material, especially the interface between the cooling channels and the product molding surface. Because this area bears the dual effects of molding pressure and temperature stress, the cumulative effect over a long period leads to mold material fatigue, making it highly susceptible to cracks between the channels and the product molding surface. Once cracks form, the water used for cooling inside the mold will seep into the chamber containing the molten aluminum. During aluminum product manufacturing, the contact between water and high-temperature molten aluminum will instantly trigger a violent chemical reaction, producing a large amount of hydrogen gas. This not only leads to changes in the composition of the molten aluminum and serious defects such as porosity in the product, but may also cause catastrophic production accidents such as explosions due to the rapid expansion of the gas, seriously threatening production safety and product quality. Therefore, a new mold cooling water channel structure is proposed. Utility Model Content

The blind pipe 5 is used for heat exchange with the mold, and the return water channel 15 is used to discharge the coolant after heat exchange. The cooling pipe 1 has a first external thread 17, and the heat exchange blind pipe 5 has an internal thread 51, which is threaded onto the first external thread 17. The first external thread 17 and the internal thread 51 cooperate to achieve a threaded connection between the cooling pipe 1 and the heat exchange blind pipe 5. The cooling pipe 1 has multiple grooves 18, and a first sealing ring 19 is fitted inside each groove 18. The first sealing ring 19 is fitted into the heat exchange blind pipe 5. The grooves 18 are used to install the first sealing ring 19, which improves the sealing performance at the connection between the cooling pipe 1 and the heat exchange blind pipe 5. (Inlet water channel...) The inlet channel 11 has a water inlet hole 13, and the return channel 15 has a water outlet hole 16.

The water supply pipe 3 is provided with a third external thread 3. 1. The third external thread 31 is threaded into the second threaded hole 14. The third external thread 31 is used to cooperate with the second threaded hole 14 to realize the threaded connection between the water supply pipe 3 and the cooling pipe 1. A second sealing ring 32 is sleeved on the water supply pipe 3, and the second sealing ring 32 is set on one side of the first threaded hole 12. The second sealing ring 32 is used to improve the sealing performance at the connection between the cooling pipe 1 and the water supply pipe 3.

After the heat exchange is completed, the coolant flows from the return channel 15 into the outlet pipe. The hexagonal groove 21 is used to facilitate the unscrewing of the plug 2. The heat exchange blind pipe 5 is a thin-walled copper pipe.
