Description

Technical Field

[0001] The utility model relates to the technical field of die-casting equipment, in particular to an aluminum alloy die-casting machine with a cooling function. Background Art

[0002] Aluminum alloy die-casting is an important metal forming process. It uses a die-casting machine to hydraulically inject molten aluminum alloy into a mold, and then cools and forms a solid metal casting. This process has the advantages of high production efficiency, high casting dimensional accuracy, and good surface quality.

[0003] In the field of die-casting processing, a common problem is that many traditional die-casting machines have a slow mold cooling rate during operation. The mold takes a long time to cool, resulting in low production efficiency. In addition, the slow cooling rate may also cause increased internal stress in aluminum alloy castings, thereby affecting the mechanical properties and dimensional stability of the castings, and even causing defects on the casting surface. In order to solve the above problems, the utility model provides an aluminum alloy die-casting machine with a cooling function. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings of the prior art and to propose an aluminum alloy die-casting machine with a cooling function.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] An aluminum alloy die-casting machine with a cooling function includes a workbench, the upper surface of the workbench is fixedly connected to a lower mold, a cooling water trough is opened inside the lower mold, the lower end of one side of the lower mold is fixedly connected to a water inlet, and the upper end of the other side of the lower mold is fixedly connected to a water outlet, the water inlet and the water outlet are both connected to the cooling water trough, one side of the water outlet is fixedly connected to a spiral cooling water pipe, the inside of the workbench is fixedly connected to a water tank, the upper surface of the workbench is fixedly connected to a support frame, and the front of the support frame is fixedly connected to several cooling fans.

[0007] As a further improvement of the present invention, the other end of the spiral cooling water pipe is fixedly connected to a circulating water pipe, and the other end of the circulating water pipe is fixedly connected to a water storage tank.

[0008] As a further improvement of the present invention, a water pump is fixedly connected to the upper surface of the water tank, a water inlet end of the water pump is fixedly connected to a water pumping pipe, and the other end of the water pumping pipe is fixedly connected to the water tank.

[0009] As a further improvement of the present invention, the water outlet end of the water pump is fixedly connected to a water pipe, and the other end of the water pipe is fixedly connected to the water inlet.

[0010] As a further improvement of the present invention, a water adding funnel is fixedly connected to the front of the water storage tank.

[0011] As a further improvement of the present invention, two hydraulic cylinders are fixedly connected to the upper surface of the support frame, the telescopic ends of the two hydraulic cylinders are fixedly connected to the same upper mold, and a feeding pipe is provided at the upper end of the upper mold.

[0012] Beneficial effects of the utility model:

[0013] By setting up the lower mold, spiral cooling water pipe and cooling fan, when in use, the device integrates a dual cooling mechanism of water cooling and air cooling to quickly reduce the mold temperature. The water pump inputs cooling water into the cooling water tank of the lower mold, directly taking away the large amount of heat generated by the aluminum alloy raw material during the die-casting process, effectively preventing the aluminum alloy material performance degradation or mold damage caused by overheating of the mold. At the same time, the spiral cooling water pipe with a spiral structure and the cooling fan are used in conjunction, which not only accelerates the heat dissipation speed of the cooling water, but also further reduces the overall temperature of the mold through the air cooling effect, significantly improving the continuity and production efficiency of the die-casting operation. The rapid and uniform cooling helps to reduce the residual stress and thermal cracking tendency inside the aluminum alloy casting, reduces the scrap rate, and improves the overall quality of the product.

[0014] By setting up a water storage tank, the circulating cooling water system reduces the waste of water resources when in use, and reduces energy consumption by optimizing cooling efficiency. At the same time, the directional air cooling design of the cooling fan ensures the cooling effect and avoids unnecessary energy consumption, making the entire cooling process more environmentally friendly and energy-saving. The effective cooling system reduces the thermal stress caused by high-temperature operation of the mold, helps maintain the precision and shape stability of the mold, extends the service life of the mold, and reduces the frequency and cost of mold replacement.

[0015] In summary, the utility model not only improves production efficiency and ensures product quality, but also achieves multiple benefits such as energy saving and consumption reduction and extends mold life. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0022] Reference Figures 1-4 , an aluminum alloy die-casting machine with cooling function, includes a workbench 1, a lower mold 2 is fixedly connected to the upper surface of the workbench 1, a cooling water trough 3 is opened inside the lower mold 2, the lower end of one side of the lower mold 2 is fixedly connected to a water inlet 4, and the upper end of the other side of the lower mold 2 is fixedly connected to a water outlet 5, the water inlet 4 and the water outlet 5 are both connected to the cooling water trough 3, one side of the water outlet 5 is fixedly connected to a spiral cooling water pipe 6, the inside of the workbench 1 is fixedly connected to a water tank 7, the upper surface of the workbench 1 is fixedly connected to a support frame 8, and the front of the support frame 8 is fixedly connected to several cooling fans 9.

[0023] In the present invention, the other end of the spiral cooling water pipe 6 is fixedly connected to a circulating water pipe 10, and the other end of the circulating water pipe 10 is fixedly connected to the water tank 7. The upper surface of the water tank 7 is fixedly connected to a water pump 11, and the water inlet end of the water pump 11 is fixedly connected to a pumping pipe 12, and the other end of the pumping pipe 12 is fixedly connected to the water tank 7. The water outlet end of the water pump 11 is fixedly connected to a water supply pipe 13, and the other end of the water supply pipe 13 is fixedly connected to the water inlet 4. A water adding funnel 14 is fixedly connected to the front of the water tank 7. The cooling water inside the water tank 7 is input into the cooling water trough 3 of the lower mold 2 through the water pump 11 through the pumping pipe 12, the water supply pipe 13 and the water inlet 4. After flowing in the cooling water trough 3, the cooling water enters the spiral cooling water pipe 6 from the water outlet 5, and finally returns to the water tank 7 through the circulating water pipe 10, and cooling water is input into the water tank 7 through the setting of the water adding funnel 14.

[0024] Two hydraulic cylinders 15 are fixedly connected to the upper surface of the support frame 8. The telescopic ends of the two hydraulic cylinders 15 are fixedly connected to the same upper mold 16. A feeding pipe 17 is provided at the upper end of the upper mold 16. The hydraulic cylinder 15 is used to drive the upper mold 16 to move up and down to complete the closing with the lower mold 2.

[0025] When the utility model is used, the hydraulic cylinder 15 is first started to drive the upper mold 16 to move downward until the upper mold 16 and the lower mold 2 are closed. At the same time, the feeding device is connected to the feeding pipe 17, and the aluminum alloy raw material is input into the lower mold 2 and the upper mold 16 through the feeding pipe 17. Then, the water pump 11 is started to extract the cooling water inside the water tank 7 through the water pumping pipe 12 and input it into the cooling water tank 3 of the lower mold 2 through the water supply pipe 13 and the water inlet 4. The cooling water flows in the cooling water tank 3 and takes away the heat of the aluminum alloy raw material in the lower mold 2. Then it enters the spiral cooling water pipe 6 from the water outlet 5, thereby achieving the water cooling effect. Finally, the cooling water returns to the water storage tank 7 through the circulating water pipe 10, and finally the cooling fan 9 is started to cool the spiral cooling water pipe 6. The spiral structure of the spiral cooling water pipe 6 can cooperate with the cooling fan 9 to quickly cool the cooling water with heat. While the cooling fan 9 cools the spiral cooling water pipe 6, it can also perform air cooling on the lower mold 2 and the upper mold 16, thereby integrating water cooling and air cooling to quickly cool the lower mold 2.
