Description

Technical Field

[0001] This utility model relates to the technical field of aluminum alloy casting, and in particular to a cooling device for aluminum alloy casting molds. Background Technology

[0002] Die casting is a manufacturing process that uses pressure to inject molten metal into a reusable mold, where it cools and solidifies, resulting in complex-shaped metal parts. The main raw material for aluminum alloy die casting is aluminum alloy ingots. The molten aluminum alloy solution is injected into the mold cavity under high pressure, and after cooling, it forms a fixed-shape aluminum alloy part. This process is well-suited for modern large-scale production of a wide range of metal parts and has relatively mature production and post-processing techniques. It can produce perfect and complex metal parts. The die casting process involves the use of a furnace, metal, a die casting machine, and molds.

[0003] In existing technologies, water cooling is typically used to rapidly cool the mold during die casting. The mold is designed with a cooling chamber, through which flowing cooling water lowers the mold temperature, allowing the aluminum alloy to cool and solidify quickly within the mold. However, currently widely used cooling devices rely solely on the inlet and outlet pipes of the cooling water channel for circulation. This design can lead to a chaotic flow path of the cooling water within the cooling chamber, potentially weakening the cooling effect on the mold. Utility Model Content

[0004] This utility model aims to at least partially solve one of the technical problems in the related art.

[0005] Therefore, the purpose of this utility model is to propose a cooling device for aluminum alloy casting molds. By introducing a separator, the internal space of the cooling chamber is cleverly divided in an orderly manner, thereby enabling precise control of the flow path of cooling water in the cooling chamber, thus optimizing the flow efficiency of cooling water, improving the cooling rate and forming quality of the casting, and helping to achieve rapid cooling and forming of the casting.

[0006] To achieve the above objectives, this utility model proposes a cooling device for an aluminum alloy casting mold, including a die-casting mold. The die-casting mold has a cooling chamber inside, with an inlet and an outlet. The inlet is connected to a cooling water tank via an inlet pipe, and the outlet is connected to the cooling water tank via an outlet pipe. A partition is provided inside the cooling chamber, dividing it into a cooling zone and a drainage zone. The cooling zone and the drainage zone are connected by two channels, located above and below the partition, respectively. A sealing head is provided in the lower channel to block the lower channel. The sealing head is hollow, with its top end abutting against the partition and its bottom end penetrating the outlet and connected to a driving component.

[0007] In addition, the aluminum alloy casting mold cooling device proposed in the application may also have the following additional technical features:

[0008] Specifically, the water outlet is located at the lower part of the cooling chamber.

[0009] Specifically, the partition includes two partitions, wherein a drainage zone is formed between the two partitions and the inner wall of the cooling chamber, and the drainage zone is located inside the cooling zone.

[0010] Specifically, the driving component includes a rotating sleeve, wherein the rotating sleeve is movably disposed outside the die-casting mold and sleeved outside the sealing head, the outer wall of the sealing head is provided with a spiral groove, the inner wall of the rotating sleeve is provided with a slider, and the slider is slidably disposed in the groove.

[0011] Specifically, the top of the sealing head is provided with an embedding groove, and the bottom of the separator extends into the embedding groove.

[0012] Specifically, the sealing head has a silicone layer on its outer side.

[0013] Compared with the prior art, the beneficial effects of this application are:

[0014] 1. By introducing partitions, the internal space of the cooling chamber is cleverly divided in an orderly manner, thereby enabling precise control of the flow path of cooling water in the cooling chamber, thus optimizing the flow efficiency of cooling water, improving the cooling rate and molding quality of castings, and helping to achieve rapid cooling and molding of castings.

[0015] 2. By moving the plug, the opening and closing status of the corresponding channels can be precisely controlled, thereby ensuring smooth water circulation and efficient drainage in the cooling chamber.

Detailed Implementation

[0022] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0023] The cooling device for aluminum alloy casting molds according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0024] like Figures 1-3 As shown, the aluminum alloy casting mold cooling device of this utility model embodiment may include a die-casting mold 10, and a cooling chamber 20 is provided inside the die-casting mold 10. The cooling chamber 20 is provided with an inlet 21 and an outlet 22, with the outlet 22 located at the lower part of the cooling chamber 20. The inlet 21 is connected to the cooling water tank 40 through an inlet pipe 41, and the outlet 22 is connected to the cooling water tank 40 through an outlet pipe 42.

[0025] It should be noted that the inlet pipe 41 described in this embodiment can unidirectionally transport the cooling water in the cooling water tank 40 to the cooling chamber 20, and the outlet pipe 42 described in this embodiment can unidirectionally transport the cooling water in the cooling chamber 20 to the cooling water tank 40.

[0026] The cooling chamber 20 is equipped with a partition 30, which divides the cooling chamber 20 into a cooling zone 201 and a drainage zone 202. The cooling zone 201 and the drainage zone 202 are connected by two channels 60, located above and below the partition 30, respectively. A sealing head 50 is installed in the lower channel 60 to seal it. The sealing head 50 is hollow, with its top end abutting against the partition 30 and its bottom end penetrating the outlet 22 and connecting to the drive component. An embedding groove 52 is formed at the top of the sealing head 50, and the bottom of the partition 30 extends into the embedding groove 52. A silicone layer (not shown in the figure) is provided on the outside of the sealing head 50 to ensure the sealing performance of the sealing head 50 to the outlet 22.

[0027] It should be noted that the driving component described in this embodiment can control the movement of the sealing head 50, thereby precisely controlling the opening and closing state of the corresponding channel 60, and thus ensuring smooth water circulation and efficient drainage in the cooling chamber 20.

[0028] The partition 30 may include two partitions 31, wherein a drainage area 202 is formed between the two partitions 31 and the inner wall of the cooling chamber 20, and the drainage area 202 is located inside the cooling area 201.

[0029] It should be noted that the separator 30 described in this embodiment can be designed according to different models of die-casting mold 10. The separator 30 can cleverly divide the internal space of the cooling chamber 20 in an orderly manner, thereby accurately controlling the flow path of cooling water in the cooling chamber 20, thus optimizing the flow efficiency of cooling water, improving the cooling rate and molding quality of the casting, and helping to achieve rapid cooling and molding of the casting.

[0030] As one possible scenario, the drainage zone 202 and the cooling zone 201 are arranged side by side, and are located on both sides of the partition 30. The partition 30 may include a partition 31, and the drainage zone 202 is formed between the partition 31 and the inner wall of the cooling chamber 20.

[0031] The driving component may include a rotating sleeve 70, which is movably disposed on the outside of the die-casting mold 10 and sleeved on the outside of the sealing head 50. The water outlet pipe 42 is movably connected to the rotating sleeve 70, which can ensure that the water in the cooling chamber 20 is smoothly discharged from the sealing head 50 to the water outlet pipe 42. The outer wall of the sealing head 50 is provided with a spiral groove 51, and the inner wall of the rotating sleeve 70 is provided with a slider 71, which is slidably disposed in the groove 51.

[0032] It should be noted that by cooperating with the slider 71 and the groove 51, the forward and reverse rotation of the rotating sleeve 70 described in this embodiment can be controlled to control the corresponding linear movement of the sealing head 50, and the rotation of the rotating sleeve 70 can be controlled manually or mechanically.

[0033] Specifically, in the actual cooling process of aluminum alloy castings, in the initial stage, the cooling chamber 20 is first filled with water. At this time, the rotating sleeve 70 is rotated to control the movement of the sealing head 50, causing it to contact the separator 30 and close the lower channel 60. Water entering the cooling chamber 20 from the inlet pipe 41 first enters the cooling zone 201. After the cooling zone 201 is full, it enters the drainage zone 202 through the upper channel 60, and finally drains from the inside of the sealing head 50 into the outlet pipe 42, thus ensuring smooth water circulation within the cooling chamber 20. Furthermore, the flow path of the cooling water within the cooling chamber 20 is limited, thereby optimizing the flow efficiency of the cooling water, improving the cooling rate and forming quality of the casting, and facilitating rapid cooling and forming of the casting.

[0034] At the end of the die-casting cooling process for aluminum alloy castings, all the water in the cooling chamber 20 needs to be drained. At this time, the lower channel 60 is opened, and the water in the cooling zone 201 and the drainage zone 202 can be discharged from the cooling chamber 20 through the lower channel 60, thereby ensuring efficient drainage of the water flow in the cooling chamber 20.

[0035] In summary, the aluminum alloy casting mold cooling device of this utility model, through the introduction of a separator, cleverly divides the internal space of the cooling chamber in an orderly manner, thereby enabling precise control of the flow path of the cooling water in the cooling chamber, thus optimizing the flow efficiency of the cooling water, improving the cooling rate and forming quality of the casting, and helping to achieve rapid cooling and forming of the casting.
