Technical Field

[0001] This utility model relates to the field of mold temperature controller technology, and in particular to a mold temperature controller inlet and outlet water module. Background Technology

[0002] Mold temperature controllers are key devices used in industrial production to control equipment temperature. They achieve heat transfer and regulation through a water circulation system.

[0003] Traditional mold temperature controllers often use decentralized pipeline connections for their inlet and outlet water systems. Each component (such as check valves, solenoid valves, connecting pipes, etc.) is installed independently, which results in problems such as complex pipeline layout and assembly processes, low assembly efficiency, inconvenient maintenance, and occupation of installation space.

[0004] In addition, the decentralized structure can easily lead to uneven water resistance, affecting the accuracy of temperature control, and the large number of pipe interfaces increases the risk of leakage.

[0005] To solve the above problems, it is necessary to design an integrated inlet and outlet water module, which can simplify the system structure and improve operational stability by integrating core components and pipelines. Summary of the Invention

Detailed Implementation

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0018] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0019] like Figures 1-3 As shown, a mold temperature controller inlet / outlet water module is installed inside the mold temperature controller, including a module body 1 installed inside the mold temperature controller. The top surface of module body 1 is equipped with an inlet check valve 2, a circulation check valve 3 and a solenoid valve 4; A pressure connection pipe 5 is provided on the bottom surface of the module body 1; The front side of module body 1 is provided with system water outlet pipe 6, water inlet connection pipe 7, heat exchange connection pipe 8 and pressurization connection pipe 9; The rear side of the module body 1 is provided with a system water inlet pipe 10 and a water outlet connection pipe 11; A cold water outlet pipe 12 is provided on the left side of the module body 1; A cold water inlet pipe 13 is provided on the right side of the module body 1; The cold water inlet pipe 13 and the cold water outlet pipe 12 are connected inside the module body 1 for the circulation of cooling water; The system inlet pipe 10 and the inlet connection pipe 7 are connected inside the module body 1 to introduce external water. The pressurized connecting pipe 9 is connected to the inlet one-way valve 2 inside the module body 1, and is used to transport pressurized water. The heat exchange connecting pipe 8 is connected to the circulation check valve 3 inside the module body 1 for the return flow of the water after circulation cooling. The system outlet pipe 6 is connected to the outlet connection pipe 11 and the inlet check valve 2 respectively, and the solenoid valve 4 controls the switching connection between the system outlet pipe 6 and the outlet connection pipe 11 and the inlet check valve 2 (that is, the solenoid valve 4 can switch the system outlet pipe 6 to be connected to the outlet connection pipe 11, or the system outlet pipe 6 to be connected to the inlet check valve 2). The pressure connection pipe 5 is connected to the connection point of the pressurizing connection pipe 9 and the water inlet check valve 2. The pressure connection pipe 5 is connected to the pressure switch inside the mold temperature controller. The pressure switch is electrically connected to the solenoid valve 4. The pressure switch is used to detect the water pressure connected between the pressurizing connection pipe 9 and the water inlet check valve 2 in real time. When the pressure switch detects abnormal water pressure, it can control the solenoid valve 4 to switch its working state. For example, when the pressure switch detects that the water pressure is too high, it controls the solenoid valve 4 to switch the connection between the system outlet pipe 6 and the outlet connection pipe 11, so that the water that has been introduced can be discharged, thus ensuring the safety and reliability of the mold temperature controller.

[0020] The excessive water pressure is caused by the fact that after the water is continuously heated by the heating tank, the cooling and heat absorption rate of the heat exchanger is lower than the heating rate of the water, which leads to an increase in water temperature and volume expansion in the circulating water circuit, and consequently, an increase in pressure in the pipeline.

[0021] The system inlet pipe 10 is connected to an external filter. The system inlet pipe 10 is used to introduce pure water that has been filtered by the external filter to prevent impurities from clogging the pipe or damaging the components.

[0022] The water inlet connection pipe 7 is connected to the input end of the booster pump in the mold temperature controller, and the pressurization connection pipe 9 is connected to the output end of the booster pump in the mold temperature controller. After the booster pump pressurizes the water, it is delivered to the water inlet check valve 2 through the pressurization connection pipe 9.

[0023] Both the inlet check valve 2 and the circulation check valve 3 are connected to the input end of the heating water tank inside the mold temperature controller. The output end of the heating water tank is connected to the input end of the customer equipment. The output end of the customer equipment is connected to the system outlet pipe 6 through the circulation pipe. The heating water tank provides heating for the water body and then introduces the heated water body into the customer equipment to provide heat to the customer equipment. When the pressure switch does not detect abnormal water pressure, the system outlet pipe 6 and the inlet check valve 2 are in a conductive state, so that the system outlet pipe 6, the inlet check valve 2, the heating water tank, the customer equipment and the circulation pipe form a circulating water circuit; The circulation pipe also has the input end of a heat exchanger connected in series, and the output end of the heat exchanger is connected to the input end of the heat exchange connection pipe 8. The output end of the heat exchange connection pipe 8 is connected to the input end of the circulation check valve 3. A portion of the water returning from the customer's equipment enters the heat exchanger, is cooled by heat exchange, and then is connected to the heat exchange connection pipe 8 through the output end of the heat exchanger. The heat exchange connection pipe 8 is then connected to the circulation check valve 3, and finally the water flows back to the heating water tank through the circulation check valve 3. The cold water inlet pipe 13 is connected to the external cooling water, and the cold water outlet pipe 12 is connected to the heat exchanger, and the cooling water is introduced into the heat exchanger. The cooling water absorbs heat in the heat exchanger, that is, it absorbs the high-temperature water flowing into the heat exchanger, thereby achieving the cooling effect of the high-temperature water. In order to prevent the water flowing back to the heating water tank from being too hot and affecting the heating quality of the user equipment on the materials. In addition, the cooling water entering the heat exchanger absorbs the high-temperature water and is then discharged from the heat exchanger's outlet.

[0024] Working principle: After being filtered by an external filter, the external water enters the module body 1 through the system inlet pipe 10, is connected to the inlet connection pipe 7 through an internal passage, and then enters the booster pump; the water pressurized by the booster pump enters the module body 1 through the pressurization connection pipe 9, is connected to the inlet check valve 2 through an internal passage, and finally flows into the heating water tank. The hot water output from the heating tank enters the customer's equipment and then flows back to the system outlet pipe 6 through the circulation pipe; at this time, the solenoid valve 4 controls the system outlet pipe 6 to connect with the inlet check valve 2, and the returning water enters the heating tank again through the inlet check valve 2 to form a circulation. Among them, some hot water will enter the heat exchanger through the circulation pipe. At the same time, the cold water inlet pipe 13 and the cold water outlet pipe 12 will pass external cooling water into the heat exchanger. The cooling water absorbs the high-temperature water entering the heat exchanger. After absorbing heat, the cooled water flows back to the heating water tank through the heat exchange connection pipe 8 and the circulation check valve 3 to avoid the temperature of the circulating water being too high. When the pressure switch detects that the water pressure at the connection between the pressurization connection pipe 9 and the inlet check valve 2 is too high through the pressure connection pipe 5, the pressure switch controls the solenoid valve 4 through the electrical connection to adjust the water circuit status. The solenoid valve 4 switches to connect the system outlet pipe 6 and the outlet connection pipe 11, so that the circulating high-temperature water is discharged to ensure the safe operation of the system.

[0025] It should be noted that the aforementioned customer equipment is an injection molding machine, a device used for heating and injecting plastics.
