[0002] During the filter manufacturing process, some filter components require molds. During this manufacturing process, the mold temperature of the filter needs to be controlled, for example, to cool or dissipate heat from the mold. Conventional technology typically uses a mold temperature controller or cooling water to conduct heat to the mold to achieve temperature control. Specifically, pipes are connected to the mold, and valves on the mold temperature controller or cooling water pipes are manually opened or closed to introduce water into the mold. This conventional technology presents the following problems:

[0003] (1) The existing technology for opening temperature control, drainage, and cold water operation requires manual opening or closing of the mold temperature controller or cold water valve, which is cumbersome and prone to errors. This can cause the mold temperature to be uncontrollable, resulting in product quality risks or causing water overflow in the pipes, which harms the environment.

[0004] (2) When the mold is unloaded from the equipment or stopped for production, the water in the mold cannot be drained in advance. Over time, this will cause the mold water channel to rust, affect the mold's heat conduction, and lead to unstable product quality.

[0030] The technical solution of the present invention is described in detail below. The following embodiments may be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments.

[0031] Example 1:

[0032] This embodiment provides a mold temperature control system. Figure 2 The mold temperature control system includes a water supply module 1, a pipeline module 2, a mold 3 and a control module 4. Specifically, the pipeline module 2 includes a valve assembly, and the valve assembly includes a first valve 201 and a second valve 202.

[0033] In this embodiment, the water supply module 1 is a cooling water tower. Specifically, the system can provide cold water at room temperature through the cooling water tower, that is, the temperature of the mold 3 is controlled by using cold water.

[0034] In this embodiment, the water supply module 1 is connected to the mold 3 through the pipeline module 2. Specifically, the water supply module 1 is connected to the mold 3 through the first valve 201 and the second valve 202. Specifically, the first valve 201 is used to control the water inlet of the cooling water tower, that is, the opening and closing of the water path from the cooling water tower to the mold 3; the second valve 202 is used to control the return water of the cooling water tower, that is, the opening and closing of the water path from the mold 3 to the cooling water tower.

[0035] In this embodiment, the control module 4 is connected to the valve assembly, and the control module 4 controls the water supply module 1 by controlling the valve assembly to control the temperature of the mold 3. Specifically, the control module 4 is connected to the first valve 201 and the second valve 202, respectively. The control module 4 opens the first valve 201 and the second valve 202, and controls the system to enter the cold water working mode, that is, cold water from the cooling water tower continuously enters the mold 3 through the first valve 201. After entering the mold 3, the cold water removes the heat of the mold 3 and returns to the cooling water tower through the second valve 202, forming a cycle, thereby reducing the temperature of the mold 3 and achieving the purpose of cooling the mold 3.

[0036] Example 2:

[0037] This embodiment provides a mold temperature control system. Figure 3 The mold temperature control system includes a water supply module 1, a pipeline module 2, a mold 3, a control module 4, and a mold temperature control module 5. Specifically, the pipeline module 2 includes a valve assembly, and the valve assembly includes a third valve 203, a fourth valve 204, a fifth valve 205, and a sixth valve 206.

[0038] In this embodiment, the water supply module 1 is a cooling water tower, and the mold temperature control module 5 is a mold temperature controller. Specifically, the cooling water tower can provide room temperature cold water, and the mold temperature controller can adjust the temperature of the room temperature cold water to provide water at a specified temperature.

[0039] In this embodiment, the mold temperature control module 5 is connected to the water supply module 1 and the mold 3 respectively through the pipeline module 2. Specifically, the water supply module 1 and the mold temperature control module 5 are connected via the sixth valve 206 and the fifth valve 205; the mold temperature control module 5 is connected to the mold 3 via the third valve 203 and the fourth valve 204. Specifically, the third valve 203 is used to control the water inlet of the mold temperature controller, that is, the opening and closing of the water path from the mold temperature controller to the mold 3; the fourth valve 204 is used to control the water return of the mold temperature controller, that is, the opening and closing of the water path from the mold 3 to the mold temperature controller; the fifth valve 205 is used to control the water return of the cooling water tower, that is, the opening and closing of the water path from the mold temperature controller to the cooling water tower; and the sixth valve 206 is used to control the water inlet of the cooling water tower, that is, the opening and closing of the water path from the cooling water tower to the mold temperature controller.

[0040] In this embodiment, the control module 4 is connected to the valve assembly and controls the mold temperature control module 5 by controlling the valve assembly to control the temperature of the mold 3. Specifically, the control module 4 is connected to the third valve 203, the fourth valve 204, the fifth valve 205, and the sixth valve 206, respectively. The control module 4 controls the system to enter the mold temperature working mode by opening the third valve 203, the fourth valve 204, the fifth valve 205, and the sixth valve 206. Specifically, cold water from the cooling tower enters the mold temperature controller through the sixth valve 206. The mold temperature controller adjusts the temperature of the cold water. The adjusted water enters the mold 3 through the third valve 203, removes heat from the mold 3, and then returns to the mold temperature controller through the fourth valve 204, forming a water circuit between the mold temperature controller and the mold 3, thereby lowering the temperature of the mold 3 and achieving the purpose of cooling the mold 3. Specifically, the water circulation between the mold temperature controller and the mold 3 will cause the temperature of the water in the mold temperature controller to rise. In order to ensure the subsequent cooling effect, it is necessary to detect the temperature in the mold temperature controller. When the temperature of the mold temperature controller exceeds the threshold, the water in the mold temperature controller returns to the cooling water tower through the fifth valve 205. At this time, the built-in valve inside the mold temperature controller automatically opens, and the cold water in the cooling water tower enters the mold temperature controller through the sixth valve 206, thereby achieving the purpose of lowering the temperature of the mold temperature controller.

[0041] Example 3:

[0042] This embodiment provides a mold temperature control system. Figure 4 The mold temperature control system includes a water supply module 1, a pipeline module 2, a mold 3, a control module 4, and a mold temperature control module 5. Specifically, the pipeline module 2 includes a valve assembly, which includes a first valve 201, a second valve 202, a third valve 203, a fourth valve 204, a fifth valve 205, a sixth valve 206, a seventh valve 207, and an eighth valve 208. Specifically, the first valve 201, the second valve 202, the third valve 203, the fourth valve 204, the fifth valve 205, the sixth valve 206, and the seventh valve 207 are all solenoid valves, and the eighth valve 208 is a pneumatic solenoid valve. Specifically, the seventh valve 207 is an exhaust valve, and the eighth valve 208 is an intake valve. Compressed air enters the pipeline module 2 through the eighth valve 208.

[0043] In this embodiment, the water supply module 1 is a cooling water tower, and the mold temperature control module 5 is a mold temperature controller. The system can select either a cold water mode or a mold temperature mode. Specifically, when the cold water mode is selected, the mold 3 is temperature-controlled using cold water from the cooling water tower. When the mold temperature mode is selected, the mold 3 is temperature-controlled using the mold temperature controller. Specifically, the mold temperature controller can introduce water at a set temperature into the mold 3 to control the temperature of the mold 3. Specifically, in the cold water mode, the cold water is at room temperature. In the mold temperature mode, the water temperature can be adjusted according to actual conditions.

[0044] In this embodiment, the water supply module 1 is connected to the mold temperature control module 5 via the sixth valve 206 and the fifth valve 205. The mold temperature control module 5 is connected to the mold 3 via the third valve 203 and the fourth valve 204. The water supply module 1 is connected to the mold 3 via the first valve 201 and the second valve 202. The seventh valve 206 is located between the mold temperature control module 5 and the mold 3, and the eighth valve 207 is connected to the water supply module 1 and the mold 3, respectively.

[0045] In this embodiment, the control module 4 is connected to the first valve 201, the second valve 202, the third valve 203, the fourth valve 204, the fifth valve 205, the sixth valve 206, the seventh valve 207, and the eighth valve 208, respectively. By controlling the valve assembly, the control module 4 controls the water supply module 1 or the mold temperature control module 5 to control the temperature of the mold 3. Specifically, the control module 4 can control the system to enter the cold water operating mode, the mold temperature operating mode, the drainage mode, and the exhaust mode. Specifically, the control module 4 is provided with selection buttons corresponding to the cold water operating mode, the mold temperature operating mode, the drainage mode, and the exhaust mode, respectively, which can be used to manually select the operating mode of the system. Specifically, when the mold 3 needs to be disassembled, the drainage mode is selected to drain the water in the mold 3. This prevents water from flowing out of the mold 3 during pipe removal and adversely affecting the working environment. It also prevents residual water in the mold 3 from adversely affecting the mold 3. Specifically, in both the mold temperature operating mode and the cold water operating mode, drainage is required before replacing the mold. Specifically, after replacing the mold 3, if you are going to select the mold temperature working mode, you need to first vent the mold 3. The reason is that in the mold temperature working mode, the mold temperature control module 5 is in a state of being filled with water. If there is gas in the mold 3 or the pipeline module 2, the gas cannot be released through the mold temperature control module 5. In the early stage of replacing the mold, a large amount of gas exists in the mold 3 and the pipeline module 2. Due to the large difference in heat dissipation performance between water and gas, the gas will affect the heat dissipation effect. Specifically, in the cold water working mode, since there is a certain amount of space in the cooling water tower, the gas in the pipeline / mold can be released through the loop to the cooling water tower, so there is no need to vent.

[0046] In this embodiment, when the cold water operating mode is selected by the control module 4, the control module 4 opens the first valve 201 and the second valve 202, and closes the third valve 203, the fourth valve 204, the fifth valve 205, the sixth valve 206, the seventh valve 207, and the eighth valve 208. Specifically, cold water from the cooling water tower continuously enters the mold 3 through the first valve 201. After entering the mold 3, the cold water removes heat from the mold 3 and returns to the cooling water tower through the second valve 202, forming a cycle, thereby reducing the temperature of the mold 3 and achieving the purpose of cooling the mold 3.

[0047] In this embodiment, when the mold temperature operating mode is selected by the control module 4, the control module 4 opens the third valve 203, the fourth valve 204, the fifth valve 205, and the sixth valve 206, and closes the first valve 201, the second valve 202, the seventh valve 207, and the eighth valve 208. Specifically, cold water from the cooling water tower enters the mold temperature controller through the sixth valve 206. The mold temperature controller adjusts the temperature of the cold water. The adjusted water enters the mold 3 through the third valve 203, removes heat from the mold 3, and then returns to the mold temperature controller through the fourth valve 204, forming a water circuit between the mold temperature controller and the mold 3, thereby lowering the temperature of the mold 3 and cooling the mold 3.

[0048] In this embodiment, when the drainage mode is selected by the control module 4, the control module 4 opens the second valve 202 and the eighth valve 208, and closes the first valve 201, the third valve 203, the fourth valve 204, the fifth valve 205, the sixth valve 206, and the seventh valve 207. Specifically, pressurized gas enters the system through the eighth valve 208, and pushes the water in the mold 3 from the pipeline module 2 to enter the water supply module 1 through the second valve 202, thereby draining the water in the mold 3.

[0049] In this embodiment, when the exhaust mode is selected by the control module 4, the control module 4 opens the third valve 203 and the seventh valve 207, and closes the first valve 201, the second valve 202, the fourth valve 204, the fifth valve 205, the sixth valve 206, and the eighth valve 208. Specifically, the mold temperature control module 5 delivers water at a set temperature into the mold 3 through the third valve 203. The water pushes the gas in the mold 3 into the pipe module 2 and is discharged through the seventh valve 207.

[0050] Example 4:

[0051] This embodiment provides a mold temperature control system. Figure 5 The mold temperature control system includes a water supply module 1, a piping module 2, a mold 3, a control module 4, and a mold temperature control module 5. Specifically, the piping module 2 includes a valve assembly, which includes a first valve 201, a second valve 202, a third valve 203, a fourth valve 204, a fifth valve 205, a sixth valve 206, a seventh valve 207, an eighth valve 208, and a water distribution drain 209.

[0052] In this embodiment, the water supply module 1 is a cooling water tower, and the mold temperature control module 5 is a mold temperature controller. The system can select either a cold water operating mode or a mold temperature operating mode. Specifically, when the cold water operating mode is selected, the mold 3 is temperature-controlled using cold water from the cooling water tower. When the mold temperature operating mode is selected, the mold temperature controller is used to control the mold 3. Specifically, the mold temperature controller can introduce water at a set temperature into the mold 3 to control the temperature of the mold 3.

[0053] In this embodiment, the water diversion drain 209 is connected to the mold 3. The water supply module 1 is connected to the mold temperature control module 5 via the sixth valve 206 and the fifth valve 205. The mold temperature control module 5 is connected to the water diversion drain 209 via the third valve 203 and the fourth valve 204. The water supply module 1 is connected to the water diversion drain 209 via the first valve 201 and the second valve 202. The seventh valve 207 is located between the mold temperature control module 5 and the mold 3. The eighth valve 208 is connected to the water supply module 1 and the water diversion drain 209, respectively.

[0054] In this embodiment, the control module 4 is connected to the first valve 201, the second valve 202, the third valve 203, the fourth valve 204, the fifth valve 205, the sixth valve 206, the seventh valve 207, and the eighth valve 208, respectively. The control module 4 controls the water supply module 1 or the mold temperature control module 5 by controlling the valve assemblies to control the temperature of the mold 3. Specifically, the control module 4 can control the system to enter the cold water operating mode, the mold temperature operating mode, the drainage mode, and the exhaust mode. Specifically, the control module 4 is provided with selection buttons corresponding to the cold water operating mode, the mold temperature operating mode, the drainage mode, and the exhaust mode, respectively. These buttons can be used to manually select the operating mode of the system. The control module 4 controls the opening and closing of the valve assemblies according to the selected operating mode. The operating process is the same as in the third embodiment and will not be repeated here.

[0055] In this embodiment, the water distribution row 209 is used to adjust the water from the cooling water tower or mold temperature controller into multiple sets of parallel water channels to enter the mold 3. Through the multiple sets of parallel water channels, the temperature difference between the water inlet and the water outlet of the mold 3 can be reduced, the temperature inside the mold 3 can be kept balanced, and the cooling effect can be further improved.

[0056] Embodiment 5:

[0057] This embodiment describes the installation and use of the mold temperature control system described in Example 4 to further illustrate the technical solution of the present utility model. The steps for installing and using the system are as follows:

[0059] (2) The control module 4 is connected to the valve assembly.

[0060] (3) The system operating mode is manually selected through the control module 4, and the mold temperature operating mode or the cold water operating mode can be selected. When the mold temperature operating mode is selected, the water from the water supply module 1 enters the mold temperature control module 5, the water temperature is set by the mold temperature control module 5, and then enters the mold 3, removing the heat in the mold 3, thereby cooling the mold 3; when the cold water operating mode is selected, the cold water from the water supply module 1 enters the mold 3 through the pipe module 2, removing the heat in the mold 3, thereby cooling the mold 3.

[0061] (4) The system can select the drainage mode in the mold temperature working mode or the cold water working mode. The system can also select the exhaust mode in the mold temperature working mode.

[0062] This mold temperature control system, through a control module that controls the opening and closing of the valve assembly, can conveniently control the system's switching between cold water operation mode, mold temperature operation mode, drainage mode, and exhaust mode. This eliminates the need for manual pipe disassembly, improving work efficiency and reducing safety hazards and product quality risks caused by manual misoperation.
