Description

Technical Field

[0001] This utility model belongs to the field of mold temperature controller technology, specifically relating to a high-temperature water-type mold temperature controller. Background Technology

[0002] In industrial fields such as precision injection molding, die casting, composite material molding, and temperature control of chemical reaction vessels, it is often necessary to heat molds or equipment and precisely stabilize them at high temperatures of 120°C or even above 180°C. While traditional thermal oil mold temperature controllers can achieve these high temperatures, they suffer from drawbacks such as the flammability of thermal oil, high replacement costs due to aging, and significant environmental impact. Therefore, high-temperature water-based mold temperature controllers, which use water as the heat transfer medium, are becoming an increasingly important choice due to their advantages such as safety, environmental friendliness, high specific heat capacity, and low cost.

[0003] However, applying water to such high-temperature circulating systems faces severe technical challenges: First, the problem of steam contamination is particularly prominent. Water readily vaporizes under high temperature and pressure, generating steam bubbles. These bubbles accumulate and form airlocks, severely hindering water circulation, leading to a sharp decline in heat transfer efficiency and significant unevenness and fluctuations in mold temperature. Second, pressure control presents significant challenges. High-temperature water systems require maintaining high system pressure to prevent vaporization, but traditional systems lack flexible and rapid auxiliary pressure regulation methods. Third, the cooling bottleneck problem urgently needs to be solved. When high-temperature systems require rapid cooling, traditional methods of injecting cold water into the system cause drastic changes in system pressure and water level, and the cooling rate is limited by the flow rate and temperature of the cold water. Furthermore, scaling, clogging, and maintenance issues are becoming increasingly prominent. High temperatures accelerate the precipitation of dissolved minerals in the water and promote corrosion of metal pipes, leading to system blockage and reduced efficiency. Finally, safety design limitations cannot be ignored. Traditional high-temperature water systems lack adequate safety protection in steam accumulation areas, increasing the risk of system operation.

[0004] To address the aforementioned issues, existing technologies urgently need improvement. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., used to indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0024] In existing technologies, high-temperature water circulation systems face problems such as steam buildup leading to vapor lock, unstable pressure control, low cooling efficiency, insufficient safety pressure relief, and pipeline blockage. Traditional systems rely on manual venting valves to handle steam, the main circulation pump struggles to cope with pressure fluctuations, direct injection of cold water during cooling causes sudden pressure changes, single filters cannot handle high-temperature scaling, and safety pressure relief depends solely on the explosion-proof valve of the heating element. These shortcomings result in decreased temperature control accuracy, frequent maintenance, and significant safety hazards.

[0025] To address the aforementioned issues, automatic venting is implemented by establishing an independent steam venting path to prevent steam buildup; dynamic compensation is achieved by adding an electronic booster pump alongside the main water supply path to address pressure fluctuations; independent heat exchange paths are designed to prevent direct injection of cold water to improve cooling efficiency; pressure relief paths are separated between the water storage tank and the heating tank for added safety redundancy; and multi-stage filtration and check valves are employed to prevent backflow contamination in case of pipe blockage. This multi-path coordinated control system forms a comprehensive solution.

[0026] Therefore, as Figure 1 As shown, a preferred embodiment of this utility model proposes a high-temperature water-type mold temperature controller, which includes a main water supply path: a first water inlet 1, a first Y-type filter 2, a first one-way valve 3, a water storage tank 4, a water pump (not specifically shown in the figure, but pump flange 29 indicates the connection position of the water pump) and a heating tank 5 connected in sequence; a user-side circulation path: the heating tank 5 is connected to the user side through a water outlet pipe 6, and the user side is connected to the water storage tank 4 through a return water pipe 7, the return water pipe 7 being equipped with a second Y-type filter 8; a bypass pressurization path: between the first Y-type filter 2 and the first one-way valve The bypass connection between the three is an electronic booster pump 9 and a solenoid valve 10; the heat exchange cold water path is: the second inlet 11, the third Y-type filter 12, the cold water side of the heat exchanger 13, and the first drain outlet 17 are connected in sequence; the heat exchange hot water path is: the heating tank 5 is connected in sequence to the hot water side of the heat exchanger 13, the first high-temperature solenoid valve 14, the second one-way valve 15, and the water storage tank 4; the steam discharge path is: the top of the water storage tank 4 is connected in sequence to the second high-temperature solenoid valve 16 and the first drain outlet 17; the safety pressure relief path is: the top of the heating tank 5 is connected in sequence to the explosion-proof valve 18 and the second drain outlet 19.

[0027] It is understood that the main water supply path refers to the channel through which external water enters the system via the first inlet 1, which is the basic water supply line of the system. Specifically, stainless steel pipes can be used for connection. The first inlet 1 refers to the inlet of the external water source (usually softened or deionized water); the first Y-type filter 2 is used to filter impurities from the external water source, preventing impurities from entering the system; the first one-way valve 3 is used to prevent water from flowing back to the first inlet 1, ensuring the direction of water flow, and a spring-loaded check valve can be selected. The storage tank 4 is used to store the system water, acting as a buffer container to balance system pressure fluctuations, accommodate expansion water, and provide a stable suction head for the water pump (preventing pump cavitation). The water pump provides circulation power, pressurizing and delivering water from the storage tank 4 to the heating tank 5 and subsequent circuits. Specifically, it can be connected to the storage tank 4 and the heating tank 5 via the pump flange 29 respectively. The heating tank 5 is the core heating component (usually with a built-in electric heating element or similar device), heating the water to a set high temperature.

[0028] The user-side circulation path is the main working loop of the mold temperature controller. This means that the high-temperature water generated by the heating tank is delivered to the user equipment (such as the mold) requiring temperature control via the outlet pipe 6. After providing heat, the water, whose temperature has changed, returns to the storage tank 4 via the return pipe 7, thus achieving circulation. The second Y-type filter 8 is used to filter impurities such as scale, rust, sealing material debris, and polymer residues that may accumulate in the internal pipes or seals of the user-side equipment (such as the mold) during long-term high-temperature and high-pressure circulation, preventing these impurities from being carried back into the system by the circulating water. The user-side return water enters the storage tank 4 directly, rather than the heating tank 5. This is beneficial for: mixing water of different temperatures within the storage tank 4, stabilizing the water temperature, and accommodating volume expansion caused by temperature changes.

[0029] The bypass booster path refers to an auxiliary pressure compensation channel connected in parallel to the main water supply pipeline. In this bypass booster path, the electronic booster pump 9 and the solenoid valve 10 are connected in series. The electronic booster pump 9 can be a variable frequency centrifugal pump, and the solenoid valve 10 can be a normally closed two-position two-way valve. When a sudden increase in user-side flow demand leads to insufficient main water supply pressure, the solenoid valve 10 in the bypass booster path opens, and the electronic booster pump 9 starts to supplement the pressure.

[0030] The heat exchange cold water path refers to the cooling water flow channel independent of the main circulation, forming a forced cooling loop with the heat exchange hot water path. The heat exchanger 13 can be a plate heat exchanger 13 to achieve efficient heat exchange. The second inlet 11 is the inlet for the external water source (usually softened or deionized water), sharing the same source as the first inlet 1, but controlled independently. The third Y-type filter 12 is used to filter impurities from the external water source, preventing impurities from entering the heat exchanger 13. The first drain outlet 17 is the outlet for the cooled water (which has absorbed system heat) after heat exchange. The first high-temperature solenoid valve 14 is used to control the on / off state of this cooling loop; specifically, a solenoid valve with a temperature resistance of 200℃ can be used for automatic control. The second one-way valve 15 is used to prevent water from the storage tank 4 from flowing back into the heat exchanger 13, ensuring the direction of water flow; specifically, a spring-loaded check valve can be used. When the system temperature is too high and rapid cooling is required, the first high-temperature solenoid valve 14 opens, and the high-temperature water in the heating tank 5 is driven by the water pump (or uses pressure difference) to flow through the hot water side of the heat exchanger 13; in the heat exchanger 13, the high-temperature system water exchanges heat with the cooling water flowing through the cold water side, and the temperature decreases; the cooled water flows back to the water storage tank 4 through the second one-way valve 15.

[0031] The steam venting path refers to the directional steam discharge channel at the top of the water storage tank 4. The second high-temperature solenoid valve 16 controls the opening and closing of this steam venting path; a normally closed solenoid valve with a temperature resistance of 120-200℃ can be used. During system operation (especially at high temperatures), steam may accumulate at the top of the water storage tank 4. When the pressure (usually requiring an additional pressure switch or sensor in conjunction with the controller) indicates the need for venting, the second high-temperature solenoid valve 16 is triggered to open briefly, releasing the steam through the first drain port 17; after venting, the valve closes to maintain system pressure.

[0032] The safety pressure relief path refers to the overpressure protection channel at the top of the heating tank 5. The second drain outlet 19 is an emergency discharge outlet for high-temperature water / steam, typically leading to a safe area. The explosion-proof valve 18 is set with a maximum burst pressure; when the pressure exceeds this limit, the valve automatically opens mechanically or the rupture disc breaks. This safety pressure relief path is the last mechanical safety line of defense, preventing the heating tank 5 from exploding due to overpressure (such as temperature control failure, cooling failure, etc.).

[0033] Through the above technical solutions, this utility model embodiment can automatically discharge the steam accumulated at the top of the water storage tank 4, eliminating the air resistance phenomenon; quickly compensate for pressure fluctuations through the electronic booster pump 9 to maintain stable system pressure; achieve controllable cooling by using an independent heat exchange path to avoid sudden pressure changes; the dual pressure relief mechanism targets the steam pressure of the water storage tank 4 and the working pressure of the heating tank 5 respectively, improving safety redundancy; and the multi-stage filtration system effectively intercepts pipeline impurities, reducing the risk of blockage.

[0034] Furthermore, a bypass return pipe 20 is connected between the outlet pipe 6 and the return pipe 7. The bypass return pipe 20 is an independent pipe connecting the outlet and return ends on the user side, and can be made of copper. Its diameter can be set to, for example, 20 mm, according to the system flow requirements. This pipe connects to both the outlet pipe 6 and the return pipe 7 via stainless steel fittings, forming a branch connected in parallel to the user-side circulation path. A flow regulating valve (not shown in the figure), such as an electric proportional valve, can be installed on the bypass return pipe 20 to control the bypass flow ratio.

[0035] Specifically, when the flow resistance on the user side suddenly increases, causing a decrease in the flow rate of the main circulation path, some of the high-temperature water flows directly back to the storage tank 4 through the bypass return water pipe 20, preventing the main pump outlet pressure from rising sharply due to the sudden drop in flow. For example, when the mold water circuit valve is closed, the diversion effect of the bypass return water pipe 20 can maintain a stable pump outlet flow rate, preventing the generation of steam bubbles in the heating tank 5 due to insufficient local flow. At the same time, when the system is in a low-flow standby state, the bypass return water pipe 20 can provide a minimum circulation flow rate, preventing the main pump from running dry or the water flow in the heating tank 5 from stagnating. By adjusting the opening of the bypass return water pipe 20, the difference between the actual demand flow rate on the user side and the output flow rate of the main pump can be dynamically balanced, thereby suppressing pressure fluctuations. Thus, through the above technical solution, this utility model embodiment can maintain stable system pressure through the diversion effect of the bypass return water pipe 20 under conditions of changing flow resistance on the user side or low flow rate, avoiding the risk of local vaporization caused by insufficient pressure or leakage caused by excessive pressure. For example, when the water circuit valve of the mold is partially closed, the bypass flow can automatically compensate for the flow loss, keeping the water flow velocity in the heating tank 5 above the critical vaporization velocity, while controlling the system pressure fluctuation range within ±5% of the set pressure.

[0036] Furthermore, the bottom of the heating tank 5 is connected to the third drain outlet 22 via a drain valve 21. The bottom of the heating tank 5 refers to its lowest point, where scale particles and corrosion products tend to accumulate, facilitating targeted discharge. The drain valve 21 is a valve device that controls the flow of fluid; it can be implemented using a manual ball valve, allowing for periodic or emergency discharge of deposits through opening and closing operations. The third drain outlet 22 is a discharge interface independent of other drainage paths; it can be implemented using a water nozzle, used to directly discharge impurities outside the system.

[0037] Specifically, during the high-temperature water circulation process, the heating tank 5, as the core heating area, has its bottom becoming the main deposition area for scale particles and metal corrosion products due to gravity. By installing a drain valve 21 and a third drain outlet 22 in this area, the valve can be opened during system downtime or maintenance, allowing the deposits to be directly discharged from the bottom with the water flow. This design reduces interference with other drainage functions through an independent drainage path. For example, during shutdown maintenance, operators can clean the deposits by opening the bottom drain valve 21 without disassembling the heating tank 5, reducing maintenance complexity. Thus, through the above technical solution, this application can effectively prevent local blockage caused by impurities at the bottom of the heating tank 5, reduce fluctuations in circulating water flow resistance, extend the continuous operation cycle of the equipment, and simultaneously reduce labor maintenance costs and downtime.

[0038] Furthermore, a dual-channel pressure switch 26 is connected between the water storage tank 4 and the heating tank 5. The dual-channel pressure switch 26 is an electronic switch device that monitors the absolute pressure of the water storage tank 4 (to prevent steam overpressure) and the absolute pressure of the heating tank 5 (to prevent vaporization pressure loss).

[0039] Specifically, the dual-channel pressure switch 26 monitors the pressure status of the two containers in real time and automatically triggers an adjustment action when the absolute pressure exceeds the set range. For example, when the pressure in the heating tank 5 suddenly rises due to local vaporization and exceeds the safety threshold, the dual-channel pressure switch 26 immediately cuts off the power supply to the heating tube of the heating tank 5 and sounds an alarm to prevent the system from overpressure and exploding. When the pressure inside the heating tank 5 is lower than the anti-vaporization threshold, it is determined that there is a risk of leakage or steam accumulation in the system, and the shutdown protection is also triggered to prevent the high-temperature water from flashing and vaporizing due to insufficient pressure. At the same time, the dual-channel pressure switch 26 forms a closed-loop control with the electronic booster pump 9, the solenoid valve 10, and the second high-temperature solenoid valve 16: when the pressure inside the water storage tank 4 is higher than the safety threshold, the dual-channel pressure switch 26 immediately turns on the power to the second high-temperature solenoid valve 16 and opens the second high-temperature solenoid valve 16 to release pressure. When the pressure inside the water storage tank 4 is lower than the anti-vaporization threshold, the dual-channel pressure switch 26 immediately turns on the power to the electronic booster pump 9 and the solenoid valve 10, automatically starting the bypass booster pump to replenish pressure and maintain the system pressure stability. Therefore, through the above technical solution, this utility model embodiment can prevent the formation of steam bubbles due to insufficient pressure when the user-side operating conditions change suddenly or the system heating power is adjusted, while avoiding leakage of seals or rupture of pipelines due to excessive pressure. This pressure control mechanism enables the system to maintain a stable pressure environment under high-temperature operating conditions, ensuring the continuity of water circulation and reducing the risk of temperature control deviation and equipment damage caused by pressure fluctuations.

[0040] Furthermore, the first drain outlet 17 is connected via a first tee 23 to the outlet of the second high-temperature solenoid valve 16 and the outlet of the cold water side of the heat exchanger 13, respectively. The first tee 23 refers to a pipe fitting with three ports, specifically a T-type or Y-type stainless steel tee fitting, used to collect fluids from two different sources to the same outlet. The cold water outlet of the heat exchanger 13 refers to the port in the plate heat exchanger 13 used to discharge cooling water, specifically a copper alloy interface with a flange connection.

[0041] Specifically, the steam discharge path at the top of the water storage tank 4 and the cold water drainage path of the heat exchanger 13 converge at the first drain outlet 17 via the first tee 23. When the system (i.e., the dual-channel pressure switch 26) detects that the steam pressure inside the water storage tank 4 exceeds the safety threshold, the second high-temperature solenoid valve 16 is energized and opened, allowing steam to flow to the drain outlet via the tee. When the heat exchanger 13 performs a cooling operation, the cold water outlet enters the drain outlet through the same tee. The drainage process under both operating conditions shares the same pipeline structure; steam and water converge and mix in the first tee 23, and the steam is cooled before being discharged. Thus, through the above technical solution, this embodiment of the invention effectively solves the pipeline redundancy problem caused by the separation of steam discharge and cooling drainage paths, while ensuring safe steam discharge. The shared drain outlet structure simplifies the external pipeline layout of the equipment and facilitates drainage management during maintenance operations.

[0042] Furthermore, the second inlet 11 is connected to the water pressure switch 25 and the cold water inlet of the heat exchanger 13 via a second tee 24. The second tee 24 is a pipe fitting with three ports, specifically a T-type or Y-type stainless steel tee fitting, used to divide the water flow at the inlet into two paths. The water pressure switch 25 is a device capable of detecting pipeline water pressure and outputting an electrical signal, specifically a mechanical pressure switch or an electronic pressure sensor, used to monitor the cold water inlet pressure in real time. The cold water inlet of the heat exchanger 13 is the inlet end of the heat exchanger 13 used to receive cooling water, specifically a copper alloy interface with a flange connection, used to introduce cooling water into the heat exchanger 13 for heat exchange.

[0043] Specifically, the diversion structure of the second three-way valve 24 divides the cooling water into two paths before it enters the heat exchanger 13: one path directly supplies cooling water to the cold water inlet of the heat exchanger 13 to maintain the cooling water supply, and the other path connects to the water pressure switch 25 to monitor the inlet water pressure in real time. When the system starts up or a sudden change in user-side resistance causes insufficient cold water pressure, the water pressure switch 25 detects that the pressure is lower than a set threshold and triggers the booster pump to start or adjusts the valve opening to quickly replenish the pressure. This diversion design avoids the mutual interference between pressure detection and cooling water delivery in a single-pipe structure, ensuring the real-time nature of pressure monitoring while guaranteeing the independence and stability of the cold water inlet path of the heat exchanger 13. Thus, through the above technical solution, this application can quickly establish the cold water inlet pressure during the system startup phase, preventing local vaporization inside the heat exchanger 13 due to insufficient pressure; when there is a sudden change in user-side resistance, real-time pressure monitoring and rapid pressurization maintain a stable cooling water flow, avoiding a decrease in heat exchange efficiency; and the independent diversion path design reduces the mutual interference between pressure detection and cooling water delivery, improving the system control accuracy and reliability.

[0044] Furthermore, a pressure gauge 27 for monitoring the water pump outlet pressure is provided on the pipeline from the water pump to the heating tank 5; a thermometer 28 for monitoring the outlet water temperature of the heating tank is provided on the pipeline from the heating tank 5 to the user side (i.e., the outlet pipe 6).

Therefore, any equivalent changes made in accordance with the claims of the present utility model shall still fall within the scope of the present utility model.
