Description

Technical Field

[0001] The utility model belongs to the field of reverse osmosis membrane element production equipment, in particular to a cooling water detection and adjustment device for an injection mold of a reverse osmosis membrane accessory. Background Art

[0002] RO (reverse osmosis) technology is an important water resource treatment method. Its highly efficient desalination and purification capabilities have made it widely used in a variety of fields, including seawater desalination, lithium extraction from salt lakes, industrial wastewater treatment, and domestic drinking water production. Due to its high efficiency, environmental friendliness, and excellent reliability, RO reverse osmosis technology has gradually become a mainstream market in the water treatment sector. Some reverse osmosis components, such as central tubes, connectors, and end caps, are produced using injection molding. During this process, a series of quality issues often arise, such as surface shrinkage, localized depressions, dimensional defects, and difficulty in demolding. These issues seriously affect the production yield of reverse osmosis membrane components and result in unnecessary cost.

[0003] After long-term on-site tracking and analysis, it was found that these problems were mainly caused by insufficient mold cooling. In existing injection molding production processes, the control of mold cooling often relies on traditional cooling systems. These cooling systems have problems such as uneven cooling and low cooling efficiency in actual applications, and cannot meet the requirements of high-precision and high-quality production. Especially when producing complex structures and high-precision parts, improper mold cooling will not only lead to surface defects on the product, but also affect the dimensional accuracy and demolding performance of the product, increasing production costs and defective rates. At the same time, during the long-term use of the mold, rust will appear in the mold cooling channel. The rust will fall off during the cooling process, affecting the water quality and reducing the cooling effect. Therefore, it is necessary to design a cooling device and use the cooling device to achieve the purpose of detection and adjustment to ensure that the cooling effect remains in the best state. Utility Model Content

[0004] The utility model provides a reverse osmosis membrane accessory injection mold cooling water detection and regulation device, the main body of which is composed of an injection mold, an electric flow valve and a filter device, wherein the electric flow valve is used to control the flow of cooling water flowing into the injection mold, the electric flow valve is connected to the water inlet end of the injection mold, the filter device is used to filter the cooling water and remove impurities contained in the cooling water, the filter device is connected to the water inlet pipe and the electric flow valve respectively, and the cooling water flows from the water inlet pipe into the filter device and then passes through the electric flow valve into the cooling channel of the injection mold. In order to detect and control the cooling water entering the injection mold, a water inlet detection box is connected between the filter device and the electric flow valve, and a water temperature detection device and a water quality detection device are installed in the water inlet detection box, so that the water filtered by the filter device first flows through the water inlet detection box and then enters the electric flow valve, and the water temperature detection device and the water quality detection device are used to detect the temperature and water quality of the cooling water, and an alarm is triggered when the detection results do not meet the standards.

[0005] In addition to testing the cooling water entering the injection mold, the cooling water flowing out of the injection mold can be tested to determine the internal cooling water mold conditions. Connect a water outlet detection box to the water outlet of the injection mold, connect the water outlet detection box to the drain pipe, install a water temperature detection device 2 and a water quality detection device 2 in the water outlet detection box, and allow the cooling water flowing out of the injection mold to flow out of the drain pipe through the water outlet detection box. Use the water temperature detection device 2 and the water quality detection device 2 to detect the temperature and water quality of the cooling water flowing out to determine whether there is rust or shedding inside the injection mold.

[0006] In order to clean the cooling channel when an abnormality occurs, a two-position three-way solenoid valve is installed between the water inlet detection box and the electric flow valve, so that the first inlet of the two-position three-way solenoid valve is connected to the water inlet detection box, the second inlet of the two-position three-way solenoid valve is connected to the air intake pipe, and the outlet of the two-position three-way solenoid valve is connected to the electric flow valve. Cooling water or air in the air intake pipe can enter the electric flow valve through the two-position three-way solenoid valve. When the cooling water is blocked, the cooling channel of the injection mold can be blown and cleaned through the air intake pipe.

[0007] In order to quickly discharge the impurities cleaned out of the injection mold, a two-position three-way solenoid valve 2 is installed between the water outlet detection box and the injection mold, so that the inlet of the two-position three-way solenoid valve 1 is connected to the injection mold, and the first outlet of the two-position three-way solenoid valve 2 is connected to the water outlet detection box. The second outlet of the two-position three-way solenoid valve 2 is connected to an exhaust pipe, so that the impurities discharged from the injection mold can enter the drain pipe or the exhaust pipe through the two outlets of the two-position three-way solenoid valve 2. When air blowing cleaning is performed, the port entering the exhaust pipe is blocked, and the impurities cleaned by air blowing are discharged through the exhaust pipe.

[0008] The utility model provides a reverse osmosis membrane accessory injection mold cooling water detection and regulation device that can perform real-time detection of cooling water during the mold cooling process. By detecting the water temperature and water quality of the cooling water, the cooling water can be promptly treated to ensure that the cooling effect reaches the optimal state. By detecting the outflowing cooling water, the internal condition of the cooling channel of the injection mold can be effectively judged. The injection mold can be quickly cleaned by air flow, avoiding the impact of water quality degradation caused by aging of the injection mold on the cooling effect. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0012] To further illustrate the concept of the present invention, the following will further describe the specific implementation of the present invention with reference to the accompanying drawings:

[0013] A cooling water detection and regulation device for a reverse osmosis membrane component injection mold consists of an injection mold 5, an electric flow valve 4, an inlet water detection box 2, an outlet water detection box 7, and a filter 1. The filter 1 utilizes a conventional existing water filter 1, ensuring effective filtration of the cooling water. The electric flow valve 4 controls the cooling water flow rate, while the injection mold 5 is used for injection molding reverse osmosis membrane components. Cooling water is injected into the internal cooling channels to cool the components.

[0014] The water inlet detection box 2 is a water tank. A water temperature detection device 9 and a water quality detection device 10 are installed on the top of the water inlet detection box 2 to detect the water temperature and TDS value of the cooling water. The water temperature detection device 9 and the water quality detection device 10 are detection devices of existing models, which can achieve the detection purpose. The water outlet detection box 7 is a water tank. A water temperature detection device 12 and a water quality detection device 13 are installed on the top of the water outlet detection box 7 to detect the water temperature and turbidity of the cooling water. The above water temperature detection device and water quality detection device are detection devices of existing models, which can achieve the detection purpose. The water inlet and outlet ends of the water inlet detection box 2 and the water outlet detection box 7 are both set at the upper ends of the opposite side walls. Take two two-position three-way solenoid valves as the two-position three-way solenoid valve 13 and the two-position three-way solenoid valve 26 respectively, and use the adjustable characteristics of the two-position three-way solenoid valve to control the flow of the coolant channel.

[0015] The water inlet of filter device 1 is connected to water inlet pipe 8, and the water outlet of filter device 1 is connected to the water inlet of water inlet detection box 2. A two-position three-way solenoid valve 13 is configured as a two-in, one-out arrangement. The water outlet of water inlet detection box 2 is connected to one inlet of two-position three-way solenoid valve 13, and the other inlet of two-position three-way solenoid valve 13 is connected to air inlet pipe 14, which is connected to an external high-pressure air source. The outlet of two-position three-way solenoid valve 13 is then connected to electric flow valve 4, which is in turn connected to the cooling channel inlet of injection mold 5. After being filtered by filter device 1, cooling water can flow through water inlet detection box 2, two-position three-way solenoid valve 13, and electric flow valve 4 before entering the cooling channel of injection mold 5. The two-position three-way solenoid valve 26 is set in a one-in-two-out configuration. The cooling channel outlet of the injection mold 5 is connected to the inlet of the two-position three-way solenoid valve 26, one outlet of the two-position three-way solenoid valve 26 is connected to the water inlet end of the water outlet detection box 7, and the other outlet of the two-position three-way solenoid valve 26 is connected to the exhaust pipe 15. Then, the water outlet end of the water outlet detection box 7 is connected to the drain pipe 11. The coolant of the injection mold 5 can be discharged from the drain pipe 11 through the two-position three-way solenoid valve 26 and the water outlet detection box 7. Figure 1 shown.

[0016] During daily production, the inlet channel of the air intake pipe 14 of the two-position three-way solenoid valve 13 and the outlet channel of the exhaust pipe 15 of the two-position three-way solenoid valve 26 are closed. The cooling water is filtered by the filter device 1 and flows into the water inlet detection box 2 for detection. The cooling water that passes the detection flows through the two-position three-way solenoid valve 13 and the electric flow valve 4 into the injection mold 5 for cooling operation. The cooling water is then discharged from the drain pipe 11 through the two-position three-way solenoid valve 26 and the water outlet detection box 7. If no problems are detected in the water inlet detection box 2 and the water outlet detection box 7, normal production is maintained.

[0017] If the inlet water test box 2 detects a water temperature above 25°C or a TDS value above 500 mg / L, an alarm will sound, indicating that the cooling water temperature is substandard or not being effectively filtered. If the outlet water test box 7 detects a water temperature above 80°C or a turbidity greater than 5 NTU, an alarm will sound, indicating that the cooling water temperature is substandard or the cooling water is contaminated. The machine will be shut down to investigate the cause of the abnormality. If the abnormality is detected by the inlet water test box 2, the problem of the cooling water front-end treatment will be repaired and eliminated. If the water outlet detection box 7 detects an abnormality, when it is due to abnormal water temperature, the cause of the abnormality should be checked and investigated; when the water turbidity is abnormal, it means that impurities such as rust detachment or abnormal water quality in the cooling channel of the injection mold 5 that seriously affect the cooling effect, the technician should first shut down the machine, control the cooling water inlet of the two-position three-way solenoid valve 13 and the cooling water outlet of the two-position three-way solenoid valve 26 to be closed, open the air intake pipe 14 inlet of the two-position three-way solenoid valve 13 and the exhaust pipe 15 outlet of the two-position three-way solenoid valve 26, and introduce high-pressure gas into the cooling channel of the injection mold 5 through the air intake pipe 14, use the high-pressure gas to blow out the impurities in the cooling channel, and discharge the impurities through the exhaust pipe 15. After cleaning, check the water quality, and start the machine after it returns to normal.

[0018] The present invention also includes a control device in the actual production process, through which various electrical equipment such as the electric flow valve 4, the water quality detection device, the water temperature detection device and the two-position three-way solenoid valve are controlled. However, since it does not belong to the technical improvement point of the present invention, it is not further explained. It belongs to the conventional technical means of those skilled in the art, and those skilled in the art can also implement this technical solution without explanation.

[0019] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, various changes and variations are possible. Any modifications, equivalent replacements, improvements, etc. made using the present invention should be included in the scope of protection of the present invention.
