Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0029] During the production process of the inner panel of the rear wheel arch of a vehicle, since the inner panel of the rear wheel arch is an irregular arc-shaped part with a deep drawing depth, its manufacturing cycle is long, which easily leads to temperature changes in the mold and the raw material plate. This change easily leads to unstable formability of the raw material plate, and cracking problems often occur, resulting in increased production costs.

[0030] In the prior art, in order to control the temperature change of the mold during production, a cooling device is provided in the mold. The cold air generated by the cooling device is circulated in the air pipe provided in the mold, thereby reducing the temperature of the mold. However, a disadvantage is that since the cooling device is inside the mold, the staff cannot observe whether the cooling device is operating normally during production, and needs to check it every once in a while, which affects production efficiency.

[0031] The present invention provides a mold cooling system 100 .

[0032] See also Figure 1-Figure 2In one embodiment of the present invention, the cooling system 100 of the mold includes a cooling component 1 and a detection component 2. The cooling component 1 includes a cooling mechanism 10 and two air pipes 11 arranged in the mold. The two air pipes 11 are respectively a first air pipe 11a and a second air pipe 11b. The first air pipe 11a, the cooling mechanism 10 and the first air pipe 11a are connected in sequence. The end of the first air pipe 11a away from the cooling mechanism 10 and the end of the second air pipe 11b away from the cooling mechanism 10 are respectively connected to The air outlet and air inlet ends of the air source 13 are connected; the detection component 2 is arranged outside the mold, and the detection component 2 includes an air inlet pipe 20, a detection shell 21 and a movable part 22. An active space 210 is formed in the detection shell 21, and the movable part 22 is located in the active space 210. The air inlet pipe 20 connects the active space 210 with any gas pipe 11; gas can enter the active space 210 through the air inlet pipe 20 to drive the movable part 22 to move in the active space 210; at least a part of the area on the detection shell 21 is set as a transparent area 215.

[0033] The technical solution of the present invention cools the mold through the cooling component 1, and at the same time detects whether the cooling component 1 is operating normally through the detection component 2. It can be understood that the detection component 2 includes two air pipes 11 and a cooling mechanism 10. The two air pipes are respectively a first air pipe 11a and a second air pipe 11b. The first air pipe 11a, the cooling mechanism 10 and the first air pipe 11a are connected in sequence. The gas enters the cooling mechanism 10 through the first air pipe 11a and enters the second air pipe 11b after cooling. The second air pipe 11b is mainly used to cool the mold. The cooled gas will take away part of the heat of the mold when flowing in the second air pipe 11b. In addition, the end of the first air pipe 11a away from the cooling mechanism 10 and the end of the second air pipe 11b away from the cooling mechanism 10 are respectively connected to the air outlet and the air inlet of the air source 13, so that the air pipe 11 and the cooling mechanism 10 are connected. The air source 13 forms an air flow loop to realize the circulation of gas, and the cooling effect is better without leakage of cold air. Since the active space 210 of the detection shell 21 is connected to the gas pipe 11 through the air inlet pipe 20, when the gas flows in the gas pipe 11, part of the air flow will enter the active space 210 along the air inlet pipe 20, thereby blowing the movable part 22 into an active state in the active space 210, and a transparent area 215 is provided on the detection shell 21, through which the movement of the movable part 22 can be intuitively observed, thereby determining that the cooling component 1 is operating normally; when the cooling mechanism is not operating or the air flow loop formed by the cooling component 1 leaks, the gas does not flow or the gas leaks out from the gas pipe 11, resulting in the gas not circulating or leaking. Under the action of air pressure, most of the gas flows out from the leak, making it impossible for the gas to enter the active space 210 and causing the movable part 22 to be in a stationary state.

[0034] The cooling system 100 of the present invention forms an air flow circuit through the air supply pipe 11, the cooling mechanism 10 and the air source 13 to realize gas circulation to cool the mold. By connecting a detection component to the air supply pipe 11, the state of the movable part 22 in the movable space 210 can be observed to intuitively reflect whether the cooling component 1 is operating normally. When the movable part 22 is in an active state, it indicates that the cooling component is operating normally and there is no air leakage in the air flow circuit. When the movable part 22 is in a stationary state, it indicates that the cooling component is operating abnormally, which may be that the cooling mechanism has not started normally or there is an air leakage in the air flow circuit. Therefore, by observing the movable part 20, it is possible to quickly understand whether the cooling component 1 is operating normally, and there is no need to check the cooling component 1 at regular intervals, thereby improving production efficiency.

[0035] In one embodiment, the gas source 13 may be a gas pump in the prior art, which is used to promote the flow of gas in the gas pipe 11 to achieve circulation.

[0036] In one embodiment, the air inlet pipe 20 is connected to the second air delivery pipe 11b. It can be understood that the gas in the second air delivery pipe 11b is mainly the gas cooled by the cooling mechanism 10. In order to maintain a good cooling effect on the mold, the air flow in the second air delivery pipe 11b needs to maintain smooth flow. Under normal circumstances, part of the gas will enter the activity space 210 to drive the movable part 22 to move. When there is a leak, the gas in the second air delivery pipe 11b will flow outward under the action of air pressure, so that the gas does not enter the activity space 210 to drive the movable part 22 to move. Therefore, the air inlet pipe 20 and the second air delivery pipe 11b are connected. The connection enables the movable part 22 to directly reflect the air flow conditions in the second air pipe 11b, thereby determining whether the cooling assembly 1 is working normally; in another embodiment, the air inlet pipe 20 can also be connected to the first air pipe 11a. It can be understood that the first air pipe 11a mainly provides air flow to the cooling mechanism 10. When cooling the mold, the first air pipe 11a also needs to maintain smooth gas flow to continuously provide air flow to the cooling mechanism 10 for cooling. Similarly, connecting the air inlet pipe 20 with the first air pipe 11a can also detect whether the cooling assembly 1 is working normally.

[0037] In one embodiment, the two ends of the detection shell 21 are respectively a connecting end 211 and a closed end 212, the end of the air intake pipe 20 is connected to the connecting end 211, and the movable space 210 extends from the connecting end 211 to the closed end 212; a movable gap 210a is formed between the movable part 22 and the inner wall of the movable space 210, so that the gas entering the movable space 210 through the air intake pipe 20 can drive the movable part 22 to move in the movable space 210.

[0038] It can be understood that the two ends of the detection shell 21 are respectively a connecting end 211 and a closed end 212, and the air inlet pipe 20 is connected to the connecting end 211. After the air flow enters the activity space 210, its flow direction is from the connecting end 211 toward the closed end 212, so that it is easier to drive the movable part 22 to move. The movable part 22 and the inner wall of the activity space 210 have a certain activity gap 210a. This design allows the movable part 22 to move in the activity space 210. When the gas enters the activity space 210 and the air pressure rises, the gas circulates in the activity space 210 and then flows back to the gas pipe from the air inlet pipe 20 due to the action of the air pressure, thereby realizing the circulation of gas.

[0039] In one embodiment, the connection end 211 is provided with an opening 2110 communicating with the air inlet pipe 20 . The end of the air inlet pipe 20 connected to the detection shell 21 is provided with a connector 201 . The outer edge of the connector 201 is threadedly connected to the inner wall of the opening 2110 .

[0040] As will be appreciated, in this embodiment, the opening 2110 of the connection end 211 is designed to facilitate connection with the air intake pipe 20, ensuring airtightness and structural stability. The end of the air intake pipe 20 is connected to the detection housing 21 via the connector 201. The outer edge of the connector 201 is threadedly connected to the inner wall of the opening 2110, making the connection more secure and reliable, with better airtightness and easier installation and removal. To further improve airtightness, a sealing ring can be provided between the connector 201 and the inner wall of the opening 2110 to prevent gas leakage.

[0041] In one embodiment, the movable member 22 is a movable ball 22a, and the outer diameter of the movable ball 22a is larger than the size of the opening 2110. As can be understood, this size design restricts the movable ball 22a from rotating flexibly within the movable space 210 while preventing it from falling out of the opening 2110. Furthermore, the contact surface between the movable ball 22a and the inner wall of the movable space 210 is minimized, making it more easily moved by airflow.

[0042] In addition, in other embodiments, the movable member 22 may also be a movable block or other irregularly shaped objects.

[0043] As a preferred embodiment, the detection shell 21 is installed in a vertical direction perpendicular to the horizontal direction, so that the closed end 212 is located below the connecting end 211. When the movable part 22 is not blown by the airflow, the movable part 22 is close to the opening 2110 due to the action of gravity. When the gas enters the active space 210, it can drive the movable part 22 to move in the up and down directions, so that the states of the movable part 22 when under force and when not under force are obviously different, thereby avoiding misjudgment.

[0044] In one embodiment, the detection shell 21 includes a side panel 213 and two bottom panels 214. The two ends of the side panel 213 are respectively a connecting end 211 and a closed end 212. The two bottom panels 214 are respectively connected to the connecting end 211 and the closed end 212, so as to enclose an activity space 210 by the side panel 213 and the two bottom panels 214; at least a portion of the area of ​​the side panel 213 is set as a transparent area 215.

[0045] It can be understood that the detection shell 21 is composed of side panels 213 and two bottom panels 214. The air flow enters the activity space 210 from the bottom panel 214 located at the connection end 211, blowing the movable part 22 to move between the connection end 211 and the closed end 212. The transparent area 215 is set on the side panel 213 to make it easier to observe the activity status of the movable part 22; and such a setting can also make the side panels 213 and the bottom panel 214 made of high-strength materials to ensure their stability and durability during use; and the transparent area 215 on the side panel 213 can be a window opened on the side panel 213, and can be made of other materials, such as transparent glass or transparent plastic material, to facilitate observation of the conditions in the activity space 210.

[0046] Specifically, the side panels 213 and the two bottom panels 214 are integrally formed, and the structure is more airtight.

[0047] In one embodiment, the transparent area 215 extends from the connecting end 211 to the closed end 212. It can be understood that this arrangement makes it easier to observe the movable member 22 in the movable space 210.

[0048] like Figure 2 As shown, the transparent area 215 is a long strip-shaped transparent window extending from the connecting end 211 to the closed end 212. Figure 3 As shown, the entire detection shell 21 is transparent, which can also be understood as the entire detection shell 21 being regarded as a transparent area 215 , and the detection shell 21 is made of transparent material.

[0049] See also Figure 4 In one embodiment, an air outlet pipe 23 is further provided on the bottom plate 214 connected to the closed end 212 to connect the air supply pipe 11 and the activity space 210.

[0050] It can be understood that by setting up the air outlet pipe 23, the gas enters the active space 210 from the connecting end 211 to drive the movable part 22 to move, and then returns to the gas pipe 11 from the air outlet pipe 23. The gas circulates faster in the detection component 1 and does not affect the gas circulation of the cooling component 1. In addition, the detection component 2 is equivalent to forming an air flow channel. When the gas flows in the gas pipe, part of the gas flows from the air inlet pipe 20 to the active space 210 and then returns to the gas pipe from the air outlet pipe 23. Another part of the gas flows directly in the gas pipe. Therefore, the gas flow conditions in the gas pipe 11 can also be synchronously reflected through the movable part 22.

[0051] Specifically, the air outlet pipe 23 and the air inlet pipe 20 are connected to the same air delivery pipe 11 .

[0052] In one embodiment, the detection assembly 2 further includes an airflow detection meter 24 . The airflow detection meter 24 is connected to the air inlet pipe 20 through an air supply pipe 25 . A first on-off valve 26 is provided on the air supply pipe 25 .

[0053] It can be understood that the airflow detection meter 24 is mainly used to test whether there are air leaks in the air intake pipe 20 and the detection housing 21. When there is no air leak, the airflow will enter the air supply pipe 25 and be detected by the airflow detection meter 24. When there is an air leak, the gas flows toward the leak, and no gas enters the air supply pipe 25, so it cannot be detected by the airflow detection meter 24. In addition, to ensure the service life of the airflow detection meter 24, the airflow detection meter 24 and the air supply pipe 25 are detachably connected. After the airflow detection meter 24 is removed from the air supply pipe 25, the first on-off valve 26 on the air supply pipe 25 is closed to prevent gas from leaking out of the air supply pipe 25. When the airflow detection meter 24 is connected to the air supply pipe 25, the first on-off valve 26 is opened to enable the airflow detection meter 24 to test whether there are air leaks in the air intake pipe 20 and the detection housing 21. The airflow detection meter 24 can check whether the detection component 2 itself is faulty, thereby further avoiding inaccurate detection results of the cooling component 1 due to a fault in the detection component 2.

[0054] Specifically, the airflow detection meter 24 can adopt any airflow detection meter 24 in the prior art, which will not be described in detail here.

[0055] In one embodiment, a second on-off valve 27 is provided on the air inlet pipe 20. It is understood that by providing the second on-off valve 27, the second on-off valve 27 can be opened only when it is necessary to detect whether the cooling assembly 1 is functioning properly, and closed when the mold is in use, so that the gas circulating in the cooling assembly 1 is used to cool the mold, while also extending the service life of the detection assembly 2.

[0056] In one embodiment, the cooling mechanism 10 includes at least two coolers 101, and the at least two coolers 101 are sequentially connected. It is understood that the sequential connection of the at least two coolers 101 further cools the gas. The gas in the first gas pipe 11a is first cooled in one cooler 101 and then further cooled in the other cooler 101, resulting in a better cooling effect.

[0057] In another embodiment, at least two coolers 101 are arranged in parallel, and each cooler 101 provides gas separately through the first gas pipe 11a, and the cooled gas is then uniformly output to the second gas pipe 11b, which can achieve cooling of a large amount of gas at the same time and with higher efficiency.

[0058] The above description is merely an exemplary embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made using the contents of the present invention specification and drawings under the technical concept of the present invention, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
