Description

Technical Field

[0001] The utility model relates to the technical field of injection molds, in particular to a circulating cooling system. Background Art

[0002] Injection molding, also known as injection molding, is a molding method that combines injection and molding.

[0003] The advantages of the injection molding method are fast production speed, high efficiency, automated operation, a wide variety of colors and patterns, shapes from simple to complex, sizes from large to small, and precise product size. The product is easy to update and can be made into parts with complex shapes. Injection molding is suitable for mass production and molding processing fields such as products with complex shapes. Injection molds are more common molds for the production of plastic products. They are usually composed of an upper mold and a lower mold for opening and closing and injection molding. Due to the high temperature of the injection molded product, the plastic product is easy to adhere to the mold and cannot be automatically demolded. It is usually necessary to install a cooling device on the mold to speed up the product molding efficiency and facilitate demolding.

[0004] Current injection mold cooling mechanisms use air cooling or water cooling for cooling.

[0005] Among them, water-cooled water circulation cooling has a faster cooling speed and cools the mold more evenly. Although the mold circulation cooling mechanism in the prior art can achieve circulation cooling, it cannot effectively avoid water pipe leakage, resulting in poor cooling effect and waste of water resources.

[0006] In order to solve this problem, the present application discloses a circulation cooling system. Utility Model Content

[0027] Example

[0028] In order to solve the problem that the circulating cooling system of the injection mold 10 in the prior art cannot realize leakage detection, resulting in poor cooling effect and waste of water resources, refer to Figure 1 As shown, the present application discloses a circulating cooling system, which is used to connect a circulating cooling pipeline 20 arranged on an injection mold 10, and the circulating cooling pipeline 20 is provided with a water inlet 21 and a water outlet 22 on the outside of the injection mold 10, and includes a cooling water tank 30, a water storage tank 40 and a pipeline leakage detection mechanism 50;

[0029] A tee 60 is installed on the water inlet 21 of the circulating cooling pipeline 20;

[0030] The cooling water tank 30 is connected to the tee 60 through a first pipeline 70, and a first valve 80 is installed at the joint between the first pipeline 70 and the tee 60;

[0031] The water storage tank 40 is connected to the water outlet 22 of the circulating cooling pipeline 20 through the second pipeline 90, and a second valve 100 is installed at the joint between the second pipeline 90 and the water outlet 22 of the circulating cooling pipeline 20;

[0032] The water storage tank 40 is connected to the cooling water tank 30 via a third pipe 110;

[0033] The pipeline leakage detection mechanism 50 includes an air blowing component 51 and a pressure gauge 53 . The air blowing component 51 is connected to the tee 60 through a fourth pipeline 54 . The pressure gauge 53 is connected to the fourth pipeline 54 . A third valve 55 is installed at the connection between the fourth pipeline 54 and the tee 60 .

[0034] In order to realize water circulation between the circulating cooling pipeline 20 in the injection mold 10 and the cooling water tank and the water storage tank, the present application installs a first water pump 120 at the connection between the first pipeline 70 and the cooling water tank 30, a second water pump 130 is installed at the connection between the second pipeline 90 and the water storage tank 40, and a third water pump 140 is installed at the connection between the third pipeline 110 and the cooling water tank 30. During specific use, the first water pump 120 is used to pump the cooling water in the cooling water tank 30 into the circulating cooling pipeline 20, the second water pump 130 is used to pump the hot water in the circulating cooling pipeline 20 into the water storage tank 40, and the third water pump 140 is used to pump the hot water in the water storage tank 40 into the cooling water tank 30.

[0035] In this embodiment, the blowing component 51 in this application is a compressor, and the compressor is connected to the fourth pipeline 54 through the fifth pipeline 52. The gas blown out by the compressor will enter the circulating cooling pipeline 20 along the fifth pipeline 52 and the fourth pipeline 54.

[0036] In addition to the above structure, the present application also provides a liquid level detector 150 in the cooling water tank 30 . During specific use, the operator determines whether to perform a water replenishment operation based on the amount of water in the cooling water tank 30 .

[0037] In the specific implementation process, firstly, normal temperature water is injected into the water storage tank 40 and the cooling water tank 30 respectively, and the cooling water tank 30 will cool the normal temperature water inside it;

[0038] Before the specific implementation of the present application, the first valve 80 and the second valve 100 are closed, and the third valve 55 is opened. At this time, the blowing assembly 51 will blow air into the circulating cooling pipeline 20 and detect the air pressure in real time through the pressure gauge 53. If the pressure gauge 53 detects an abnormality, it means that the circulating cooling pipeline 20 has a leak. At this time, the operator needs to repair the circulating cooling pipeline 20 in the injection mold 10;

[0039] When the circulating cooling pipeline 20 is tested to be qualified, the injection mold 10 can then carry out production activities, and the specific operation process is as follows:

[0040] When the injection mold 10 is injection-cooled, the second valve 100 and the third valve 55 are closed, the first valve 80 is opened, and the first water pump 120 pumps the cooling water in the cooling water tank 30 into the circulating cooling pipeline 20. When all the cooling water in the cooling water tank 30 is injected into the circulating cooling pipeline 20, the second water pump 130 pumps the normal temperature water in the water storage tank 40 into the cooling water tank 30 for further cooling.

[0041] After the mold is cooled after injection molding, the first valve 80 and the third valve 55 are closed, the second valve 100 is opened, and the second water pump 130 draws the hot water in the circulating cooling pipeline 20 into the water storage tank 40 for storage.

[0042] The above-mentioned action is recycled according to the production needs of the injection mold 10, which reduces the waste of water resources, saves production costs, and has a strong use value.
