Description

Technical Field

[0001] This utility model relates to the field of casting cooling technology, and in particular to a mold return water collection and conveying device. Background Technology

[0002] In the existing technology, after the cooling water exchanges heat through multiple cooling channels of the mold, it flows directly to the main cooling channel of the mold through the mold return water branch pipe. Due to the influence of the mold structure, the pressure and temperature of the cooling water returning from different cooling channels are different, which makes it impossible for the cooling water in the mold return branch pipe to flow out quickly. As a result, the mold return branch pipe bursts due to increased pressure or excessive temperature, affecting production efficiency and mold life.

[0003] Therefore, by developing a mold return water collection and conveying device, the return water from each mold branch pipe can be concentrated into the water collection tank without affecting the mold cooling effect. The flow rate can be automatically adjusted according to the temperature to prevent the temperature from getting too high. This can prevent the mold return branch pipe from bursting due to increased pressure or excessive temperature, and ensure that the cooling water flows more stably to the mold return water main pipe, thereby ensuring production efficiency and extending the service life of the mold.

[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0029] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments:

[0030] like Figure 1 As shown, a mold return water collection and conveying device includes a mold return water main pipe 1, a water collection component 2 and multiple mold return water branch pipes 3, wherein the water collection component 2 includes a water collection tank 21;

[0031] One end of the mold return water branch pipe 3 is connected to the cooling flow channel return water interface of the mold 4, and the other end is connected to the mold return water main pipe 1 through the water collection tank 21. A water conveying component is provided between the water collection tank 21 and the mold return water main pipe 1. The water conveying component is used to transport the cooling water of the water collection tank 21 to the mold return water main pipe 1.

[0032] Each of the mold return water branch pipes 3 is equipped with a flow regulating component 5 and a temperature sensor 6, and the temperature sensor 6 is electrically connected to the flow regulating component 5.

[0033] In this embodiment, by setting a water collection assembly 2 between the main mold return water pipe 1 and multiple mold return water branch pipes 3, the pressurized cooling water in each mold return water branch pipe 3 can flow smoothly and quickly to the water collection assembly 2, so as to release the pressure inside the pipe and avoid the mold return water branch pipe 3 from bursting due to excessive pressure.

[0034] Meanwhile, by installing a flow regulating component 5 and a temperature sensor 6 that are electrically connected to each other on the mold return water branch pipe 3, the flow regulating component 5 is controlled to adjust the flow rate of the mold return water branch pipe 3 based on the temperature of the cooling water monitored by the temperature sensor 6. That is, when the temperature is too high, the opening is adjusted to increase the water flow rate, and vice versa, the water flow rate is reduced, thereby preventing the mold return water branch pipe 3 from bursting due to excessive temperature.

[0035] The above structure, without affecting the cooling effect of mold 4, can prevent the return branch pipe of mold 4 from bursting due to increased pressure or excessive temperature, and allows the cooling water to flow more stably and controllably to the mold return main pipe 1, ensuring production efficiency and extending the service life of mold 4.

[0036] Furthermore, such as Figure 1 As shown, the water collection assembly 2 also includes a level switch 22 disposed in the water collection tank 21. The level switch 22 includes an upper level sensor 221 and a lower level sensor 222. The level switch 22 is electrically connected to the water delivery assembly.

[0037] In this embodiment, when the water level of the cooling water in the water collection tank 21 exceeds the upper liquid level sensor 221, the water supply component is activated to deliver the cooling water to the mold return water main pipe 1. When the water level is lower than the lower liquid level sensor 222, the water supply component is stopped, thereby controlling the water collection volume of the water collection tank 21 while automatically delivering the cooling water to the mold return water main pipe 1.

[0038] Furthermore, such as Figure 1 As shown, in order to improve water delivery efficiency, the water delivery assembly includes a first valve 7 and a delivery pump 8 sequentially disposed on the mold return water main pipe 1; the liquid level switch 22 is electrically connected to the first valve 7 and the delivery pump 8.

[0039] In this embodiment, when the water delivery assembly is started, the first valve 7 opens and the delivery pump 8 starts.

[0040] Furthermore, such as Figure 1 As shown, in order to ensure a stable and continuous water supply and prevent excessive cooling water in the water collection tank 21 from causing the mold return water branch pipe 3 to burst, the water supply assembly also includes a bypass pipe 9, a standby pump 10, and a second valve 11.

[0041] Both ends of the bypass pipe 9 are connected to the mold return water main pipe 1, and the second valve 11 and the standby pump 10 are installed on the bypass pipe 9;

[0042] The level switch 22 also includes a warning level sensor 223 located above the upper level sensor 221, and the backup pump 10 and the second valve 11 are electrically connected to the level switch 22.

[0043] In this embodiment, when the water level in the water collection tank 21 exceeds the expected liquid level sensor, it indicates that the delivery pump 8 is damaged. At this time, the automatic control of the backup pump 10 starts, the second valve 11 opens, and the cooling water from the water collection tank 21 is pumped to the mold return water main pipe 1 through the bypass pipe 9.

[0044] Furthermore, such as Figure 1 As shown, the flow regulating component 5 includes a flow regulating valve 51 and an electronic flow meter 52 sequentially disposed on the mold return water branch pipe 3;

[0045] The flow regulating valve 51 is electrically connected to the temperature sensor 6.

[0046] In this embodiment, the flow regulating valve 51 is controlled to adjust the flow rate of the mold return water branch pipe 3 based on the temperature of the cooling water monitored by the temperature sensor 6. That is, when the temperature is too high, the opening is adjusted to increase the water flow rate, and vice versa, to prevent the mold return water branch pipe 3 from bursting due to excessive temperature. At the same time, the cooling water flow rate of each mold return water branch pipe 3 can be viewed in real time through the electronic flow meter 52.

[0047] Furthermore, such as Figure 1 As shown, in order to filter out various impurities in the cooling water and improve the quality of the return water, the water supply assembly also includes two filters 12 respectively installed on the mold return water main pipe 1 and the bypass pipe 9.

[0048] Furthermore, such as Figure 1 As shown, in order to prevent the cooling water from flowing back and damaging the pump body when the delivery pump 8 or the standby pump 10 stops working, and to extend the service life of the pump body, the delivery assembly also includes two check valves 13 respectively installed on the mold return water main pipe 1 and the bypass pipe 9.

[0049] Furthermore, such as Figure 1 As shown, in order to avoid a large temperature difference in the cooling water supplied to the mold return water main 1, the water collection assembly 2 also includes a circulation pipe 23, a fourth valve 24 and a circulation pump 25;

[0050] The two ends of the circulation pipe 23 are respectively connected to the water collection tank 21, and the fourth valve 24 and the circulation pump 25 are installed on the circulation pipe 23.

[0051] Furthermore, such as Figure 1As shown, in order to monitor the temperature of the cooling water in the mold return water main pipe 1, a bimetallic thermometer 14 is installed at the end of the mold return water main pipe 1 away from the water collection tank 21.

[0052] For those skilled in the art, various other corresponding changes and modifications can be made based on the technical solutions and concepts described above, and all such changes and modifications should fall within the protection scope of the claims of this utility model patent.
