Description

Technical Field

[0001] The utility model relates to the technical field of die-casting mold cooling, in particular to a cyclically cooled die-casting mold. Background Art

[0002] A die-casting mold is a tool used to produce metal parts. It manufactures parts by injecting molten metal into a mold cavity and then cooling and solidifying it under high pressure. Die-casting molds are usually made of high-quality steel to withstand high temperatures and high pressures. Cooling is an important step in the die-casting process. After the metal is injected into the mold, it needs to be cooled quickly to prevent overheating and deformation. This is usually achieved by providing cooling channels in the mold, through which coolant (usually water or oil) circulates to take away the heat in the mold. The cooling rate and time need to be precisely controlled to ensure the quality of the parts. If the cooling is too fast, it may cause excessive internal stress in the parts; if the cooling is too slow, it may cause inaccurate shape or poor surface quality of the parts, and traditional cooling operations use a large amount of water. Therefore, the present application provides a die-casting mold with circulating cooling. Utility Model Content

The equipment main body 1 is provided with a mounting groove 14 on the outside, and the mold body 2 is movably connected to the inside of the mounting groove 14. A cooling bin 3 is provided inside the equipment main body 1, and a water pump 4 is fixedly connected to the inside of the cooling bin 3. The cooling exhaust pipe 5 is fixedly connected to the outside of the water pump 4. The circulating cooling pipe 19 is fixedly connected to the inside of the mold body 2. An overflow groove 6 is provided on the outside of the cooling exhaust pipe 5. A water-absorbing paperboard 22 is fixedly connected to the inside of the cooling bin 3. An exhaust port 10 is provided on the outside of the equipment main body 1. A reflux groove 11 is provided on the side of the exhaust port 10 close to the cooling bin 3. An air inlet window 12 is provided on the outside of the equipment main body 1. A ventilation fan 13 is fixedly connected to the inside of the air inlet window 12. A water inlet pipe 7 is fixedly connected to the inside of the cooling bin 3.

[0026] A water outlet groove 15 is provided on the outside of the installation groove 14, and a water inlet groove 16 is provided on the outside of the installation groove 14. The end of the cooling pipe 5 away from the water pump 4 is fixedly connected to the water outlet groove 15, the water inlet pipe 7 is fixedly connected to the water inlet groove 16, and a sinking block 8 is fixedly connected to the outside of the water inlet pipe 7. The water outlet end 17 is detachably connected to the cooling pipe 5, and the water inlet end 18 is detachably connected to the water inlet pipe 7. The absorbent paper boards 22 are horizontally interlocked and placed, and the vents 9 on the outside of the absorbent paper boards 22 are staggered and connected to each other.

[0027] Specifically, before the die-casting process, a certain amount of cooling water is injected into the cooling bin 3, and the water pump 4 is turned on for suction. The cooling pipe 5, the circulating cooling pipe 19 and the water inlet pipe 7 are interconnected to form a negative pressure to inject the cooling water into the circulating cooling pipe 19 through the water inlet pipe 7. After the circulating cooling pipe 19 is surrounded layer by layer, the heat of the mold body 2 is transported back to the cooling bin 3 through water. Under the continuous suction of the water pump 4, the cooling water completes a rapid circulation, which greatly improves the cooling efficiency of the device.

[0028] Furthermore, the outside of the mold body 2 is fixedly connected to a water outlet 17, the outside of the mold body 2 is fixedly connected to a water inlet 18, one end of the outside of the circulating cooling pipe 19 is set as a drain port 20, and the end of the circulating cooling pipe 19 away from the drain port 20 is set as a water supply port 21, the drain port 20 is fixedly connected to the water outlet 17, and the water supply port 21 is fixedly connected to the water inlet 18. The cooling pipe 5 is U-shaped and placed vertically inside the cooling bin 3. There are multiple groups of overflow troughs 6 and they are evenly distributed outside the cooling pipe 5. There are two groups of absorbent paperboards 22 and they are evenly distributed inside the cooling bin 3. Ventilation holes 9 are opened on the outside of the absorbent paperboard 22. There are multiple groups of ventilators 9 and they are evenly distributed outside the absorbent paperboard 22. There are multiple groups of ventilation fans 13 and they are evenly distributed on the inside of the air inlet window 12. There are multiple groups of reflux grooves 11 and they are evenly distributed outside the exhaust port 10. The circulating cooling pipe 19 is evenly entrenched inside the mold body 2 and is divided into multiple layers.

[0029] By making the above arrangement, during the cooling water circulation process, the water circulating back to the cooling pipe 5 is squeezed out through the overflow groove 6 and covers the surface of the cooling pipe 5. At the same time, the absorbent paper board 22 absorbs the water inside the cooling chamber 3 into the interior. Under the ventilation of the ventilation fan 13, the water evaporation efficiency is accelerated, and the splashing water is intercepted. The water droplets attached to the inner side of the exhaust port 10 are recovered. This process cools by increasing the evaporation area of ​​the liquid surface, reduces the cooling temperature difference, reduces the metal loss of the mold body 2 caused by the temperature difference, and reduces the use of cooling water.
