Technical Field
[0001] The utility model belongs to the technical field of casting molds, and particularly relates to a cooling device for die-casting mold processing. Background Art
[0002] A die-casting mold is a tool for casting metal parts, a tool for completing the die-casting process on a special die-casting forging machine. The basic die-casting process is as follows: the molten metal is first cast into the mold cavity at a low or high speed. The mold has a movable cavity surface, which is pressurized and forged during the cooling process of the molten metal, eliminating the shrinkage cavity and porosity defects of the blank, and also making the internal structure of the blank reach the broken grains in the forged state. The comprehensive mechanical properties of the blank are significantly improved. Controlling the surface temperature of the die-casting mold is very important for producing high-quality die-castings. Uneven or inappropriate die-casting mold temperature will also cause the dimensions of the castings to be unstable, the castings to be deformed during the ejection process, and defects such as thermal stress, sticking to the mold, surface depression, internal shrinkage cavity, and hot bubbles to occur. When the mold temperature difference is large, it will have varying degrees of influence on the variables in the production cycle, such as filling time, cooling time, and spraying time. The cooling device for die-casting mold processing plays an important role in the manufacturing process of die-casting molds. It can effectively control the temperature of the mold, improve the processing efficiency and the quality of the mold.
[0003] Most of the existing die-casting mold cooling devices cannot effectively remove calcium, magnesium and other ions in hard water, and thus it is easy to form scale on the surface of the device, and the metal surface under the scale will be corroded due to lack of oxygen.
[0004] The water-cooling cooling method adopted by the existing die-casting mold cooling devices often leads to uneven cooling inside the mold due to the complexity of the die-casting mold structure, which in turn affects the quality of the castings and may cause defects such as deformation and shrinkage cavity of the castings.

[0025] As Figures 1-3 shown, a die-casting mold processing cooling device includes an upper mold 1. A gate 11 is opened at the top of the upper mold 1, and raw materials are injected into the cavity through the gate 11. At the same time, a first water inlet pipe 12 is fixedly arranged outside the upper mold 1. Then, a first filter 13 threadedly connected to the first water inlet pipe 12 is fixedly arranged at one end of the first water inlet pipe 12. Cooling water is injected through the first water inlet pipe 12, and the injected water is filtered for impurities by the first filter 13, thereby preventing impurities in the injected water from accumulating inside the mold, affecting the water flow rate, and at the same time preventing impurities in the injected water from corroding the inside of the mold, improving the cooling efficiency of the cooling device and the service life of the mold.
[0026] Further, referring to the attached Figure 2 、 Figure 3 , a first water outlet pipe 14 is fixedly arranged outside the upper mold 1. At the same time, a first pipe joint 15 fixedly connected to the first water outlet pipe 14 is fixedly arranged at one end of the first water outlet pipe 14. Then, a first cooling pipe 17 is opened inside the upper mold 1. The first cooling pipes 17 all avoid each hole opened in the upper mold 1 and are mainly distributed at the central position of the upper mold 1, guiding the cooling water to be distributed at the central position of the die-casting of the upper mold 1, improving the cooling efficiency of the upper mold 1 corresponding to the moving mold position, and preventing the casting from cracking, deforming or shrinking during die-casting, thereby improving the die-casting quality of the casting.
[0027] Even further, specifically referring to the attached Figure 3 , at the same time, a first water inlet 171 connecting the first water inlet pipe 12 and the first cooling pipe 17 is opened outside the upper mold 1 corresponding to one end of the first cooling pipe 17, and a first water outlet 172 connecting the first water outlet pipe 14 and the first cooling pipe 17 is opened outside the upper mold 1 corresponding to the other end of the first cooling pipe 17.

At the same time, the first water outlet 172 is fastened by the first water outlet pipe 14 to prevent the cooling water from leaking at the interface, and further prevent the leaked cooling water from contacting the high-temperature molten metal during die-casting, generating dangerous steam, increasing the operation safety, and at the same time improving the cooling efficiency of the cooling device.
[0028] Referring to the attached Figure 1 、 Figure 2 、 Figure 3, a lower die 2 is fixedly arranged on the lower side of the upper die 1, a second water inlet pipe 23 is fixedly arranged on the outer side of the lower die 2, and a second filter 24 identical to the first filter 13 on the outer side of the upper die 1 is fixedly arranged at one end of the second water inlet pipe 23.

A second cooling pipe 27 is opened inside the lower die 2. The second cooling pipes 27 all avoid each hole position opened in the lower die 2, and the second cooling pipes 27 are mainly distributed at the central position below the moving die, guiding the cooling water to be distributed at the central position of the die casting of the lower die 2, improving the cooling efficiency of the position of the lower die 2 corresponding to the moving die.
[0029] Further, specifically refer to the appendix Figure 3 , a second water inlet 271 is opened on one side of the lower die 2, and a second water outlet 272 connected to the second water outlet pipe 25 and the second cooling pipe 27 is opened on the outer side of the lower die 2 corresponding to the other end of the second cooling pipe 27.

At the same time, the second water outlet 272 is fastened by the second water outlet pipe 25 to prevent the cooling water from leaking at the interface.
[0030] Refer to the appendix Figure 1 , Figure 2 , a fixed die base plate 3 is fixedly arranged at the bottom of the lower die 2, and two support plates 31 are fixedly arranged on the top of the fixed die base plate 3.

Thus, it is prevented that the impurities in the injected water accumulate inside the die, affecting the water flow rate, and at the same time, it is prevented that the impurities in the injected water cause corrosion to the inside of the die, improving the cooling efficiency of the cooling equipment and the service life of the die.
[0033] Secondly, by setting the structural characteristics of the first cooling pipe 17, the first cooling pipe 17 avoids all the hole positions opened on the upper die 1, and is mainly distributed at the central position of the upper die 1, guiding and distributing the cooling water at the central position of the die-casting of the upper die 1, improving the cooling efficiency of the position of the upper die 1 corresponding to the moving die, and preventing the casting from cracking, deforming or having shrinkage holes during the die-casting process, thereby improving the die-casting quality of the casting.
[0034] Finally, by setting the structural characteristics of the first cooling pipe 17 in cooperation with the first water outlet pipe 14, the cooling water is injected into the first cooling pipe 17 inside the upper die 1 through the first water inlet 171. At the same time, the cooling water is guided through the first cooling pipe 17 provided inside the upper die 1, and then the cooling water is output through the first water outlet 172. At the same time, the first water outlet 172 is fastened through the first water outlet pipe 14, preventing the cooling water from leaking at the interface, and further preventing the leaked cooling water from contacting the high-temperature molten metal during the die-casting process and generating dangerous steam, increasing the operation safety, and at the same time improving the cooling efficiency of the cooling equipment.
