Description

Technical Field

[0002] As a key temperature control device in industrial production, mold temperature controllers typically release a large amount of waste heat generated during the cooling process into the environment directly through air cooling or water cooling, resulting in energy waste. Existing patented energy-saving and consumption-reducing mold temperature controllers, patent publication number CN214188395U, include a main body, a base fixedly connected to the lower outer surface of the main body, a mold plate disposed between the inner surfaces of both sides of the main body, a heat dissipation mechanism on one side of the main body, heat dissipation holes on the other side of the main body, and a cooling device on the lower inner surface of the main body. The energy-saving and consumption-reducing mold temperature controller of this utility model, when the mold temperature controller needs to be cooled, turns on the cooling motor, which drives the first connecting rod to rotate. The first connecting rod drives the first cooling fan blade to rotate, and the first connecting rod can then drive the second connecting rod to rotate via a conveyor belt. The second connecting rod drives the second cooling fan blade to rotate. The two sets of fan blades rotate simultaneously and provide auxiliary heat dissipation to the inside of the mold temperature controller through the ventilation port, blowing the heat out through the heat dissipation hole. This saves the power consumption required for cooling the mold temperature controller and brings better application prospects.

[0003] Regarding the aforementioned technologies, the inventors believe that the following defects exist: the existing technologies lack an efficient heat recovery mechanism, resulting in high energy consumption of the mold temperature controller, which does not meet the requirements of green production. Therefore, we propose an energy-saving mold temperature controller with heat recovery to solve the above-mentioned problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an energy-saving mold temperature controller with heat recovery, which solves the problem that the lack of an efficient heat recovery mechanism in existing technologies leads to high energy consumption of mold temperature controllers, failing to meet the requirements of green production.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: an energy-saving mold temperature controller with heat recovery, including a mold temperature chamber, wherein a flow-concentrating hood is fixedly connected to the inner side of the mold temperature chamber, and the flow-concentrating hood has a frustoconical structure that is thicker at the top and thinner at the bottom;

[0006] A radiator is fixedly connected to the top opening of the flow hood. The radiator is used to draw air from the inside of the mold temperature chamber. A tailpipe is fixedly connected to the bottom surface of the flow hood. The tailpipe is connected to the flow hood. A hollow water tank mechanism is fixedly connected to the left end of the mold temperature chamber. A circulation pipe is fixedly connected inside the water tank mechanism. The rear end of the circulation pipe extends out of the water tank mechanism, and the front end of the circulation pipe is connected to the tailpipe. The end extending out of the water tank mechanism is used to discharge exhaust gas.

[0007] Preferably, an inlet pipe is fixedly connected to the outside of the water tank mechanism, the inlet pipe is used to supply liquid to the inside of the water tank mechanism, and a circulation module is fixedly connected to the inside of the mold temperature chamber.

[0008] Preferably, there are two circulation modules, which are fixedly connected to the left and right sides of the mold temperature chamber. A supply pipe is fixedly connected to the top of the water tank mechanism, which is used to supply liquid to the inside of the two circulation modules.

[0013] Beneficial effects

[0014] This invention provides an energy-saving mold temperature controller with heat recovery. Compared with the prior art, it has the following advantages:

[0015] This energy-saving mold temperature controller with heat recovery, through the cooperation of a concentrator, exhaust pipe, and circulation pipe, guides the hot air generated during the cooling process in the mold temperature chamber to the water tank mechanism. The liquid in the circulation pipe absorbs the heat of the exhaust gas, avoiding the waste of direct heat discharge in traditional technologies. Compared with existing mold temperature controllers, this invention converts the waste heat in the cooling stage into a reusable heat source, reducing energy consumption in the cooling and heating processes, achieving the energy-saving effect of "cooling and recovering simultaneously", and meeting the needs of green production.

[0016] This energy-saving mold temperature controller with heat recovery increases the contact area with the mold through two opposing circulation modules. Combined with the liquid circulation system of supply and discharge pipes, it ensures uniform cooling of the mold and avoids product defects caused by uneven temperature. The fixed structure of the bracket assembly and mounting plate enhances the stability of the equipment, while the design of the door, control panel and air inlet improves the ease of operation and heat dissipation efficiency, forming an integrated solution of "high-efficiency heat dissipation - precise temperature control - convenient maintenance", which solves the problems of high energy consumption and insufficient temperature control accuracy of traditional mold temperature controllers.

[0024] 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.

[0025] Please see Figures 1-6This utility model provides a technical solution: an energy-saving mold temperature controller with heat recovery, including a mold temperature box 1, and a flow-concentrating hood 201 fixedly connected to the inner side of the mold temperature box 1. The flow-concentrating hood 201 is a frustoconical structure with a thicker upper part and a thinner lower part.

[0026] A radiator 2011 is fixedly connected to the top opening of the flow hood 201. The radiator 2011 is used to draw air from the inside of the mold temperature chamber 1. A tail gas pipe 2012 is fixedly connected to the bottom surface of the flow hood 201. The tail gas pipe 2012 is connected to the flow hood 201. A water tank mechanism 3 with an internal hollow structure is fixedly connected to the left end of the mold temperature chamber 1. A circulation pipe 301 is fixedly connected inside the water tank mechanism 3. The rear end of the circulation pipe 301 extends out of the water tank mechanism 3, and the front end of the circulation pipe 301 is connected to the tail gas pipe 2012. One end extending out of the water tank mechanism 3 is used to discharge exhaust gas.

[0027] The converging shroud 201 inside the mold temperature chamber 1 adopts a frustoconical structure that is thicker at the top and thinner at the bottom. When the top heat sink 2011 draws air, the frustoconical structure can accelerate the convergence of air inside the mold temperature chamber 1 towards the center. The hot air is introduced into the circulation pipe 301 of the water tank mechanism 3 through the exhaust pipe 2012. The liquid in the water tank absorbs the heat of the exhaust gas, realizing heat energy recovery and avoiding energy waste caused by direct emission.

[0028] See Figures 1-3 An inlet pipe 3011 is fixedly connected to the outside of the water tank mechanism 3. The inlet pipe 3011 is used to supply liquid to the inside of the water tank mechanism 3, and a circulation module 3012 is fixedly connected to the inside of the mold temperature box 1.

[0029] Liquid is supplied to the interior through the liquid inlet pipe 3011 on the outside of the water tank mechanism 3. The circulation module 3012 on the inside of the mold temperature box 1 is connected to the supply pipe 3013. The liquid enters the circulation module 3012 through the supply pipe 3013, absorbs the heat of the mold and rises in temperature. Then, it exchanges heat with the hot air of the exhaust pipe 2012 through the circulation pipe 301, realizing the dual function of "liquid cooling heat dissipation + waste heat recovery of exhaust gas" and improving the thermal energy utilization rate.

[0030] See Figures 4-5 There are two circulation modules 3012, and the two circulation modules 3012 are fixedly connected to the left and right sides inside the mold temperature box 1. The top of the water tank mechanism 3 is fixedly connected to a supply pipe 3013, which is used to supply liquid to the inside of the two circulation modules 3012.

[0031] The two opposing circulation modules 3012 increase the contact area with the mold. The supply pipe 3013 at the top of the water tank mechanism 3 supplies liquid to the two circulation modules 3012 at the same time, ensuring uniform cooling on both sides of the mold and avoiding product deformation caused by uneven cooling. At the same time, the residual heat generated by the two circulation modules 3012 is recovered simultaneously to improve heat dissipation efficiency.

[0032] See Figures 1-6 A discharge pipe 3015 is fixedly connected to the outside of the supply pipe 3013, and a discharge pipe 3015 is fixedly connected to the right side of the circulation module 3012. The discharge pipe 3015 is used to discharge the waste liquid in the two circulation modules 3012.

[0033] The waste liquid that has absorbed heat in the circulation module 3012 can be discharged in a timely manner through the discharge pipe 3015 outside the supply pipe 3013, so as to avoid the waste liquid from stagnating and affecting the cooling effect, and to ensure the circulation efficiency of the heat transfer medium. At the same time, in conjunction with the waste heat recovery of the circulation pipe 301, a complete closed loop of "liquid supply-cooling-discharge-heat recovery" is formed, which improves the stability of the system.

[0034] See Figures 3-5 A support assembly 101 is fixedly connected to the bottom surface of the mold temperature chamber 1. There are two support assemblies 101 in total. The two support assemblies 101 are fixedly connected to the left and right sides of the bottom surface of the mold temperature chamber 1 in opposite directions. A support frame 2 for placing the mold is fixedly connected to the inside of the mold temperature chamber 1.

[0035] The equipment is stably supported by two support components 101 at the bottom of the mold temperature chamber 1. They are distributed on the left and right sides of the bottom end face to balance the center of gravity of the equipment and prevent the equipment from shifting due to vibration caused by the operation of the internal components of the mold temperature chamber 1, thus ensuring the stability of the heat recovery process.

[0036] See Figures 1-2 Mounting plates 1012 are fixedly connected to the front and rear sides of the two bracket assemblies 101, and mounting holes 1013 are provided inside the mounting plates 1012.

[0037] The equipment can be fixed to the workbench or frame through the mounting plates 1012 on the front and rear sides of the bracket assembly 101 via the mounting holes 1013, which enhances the flexibility of equipment installation, adapts to the fixed requirements of different production scenarios, and avoids fluctuations in heat recovery efficiency caused by movement.

[0038] See Figures 4-6 The front end of the mold temperature chamber 1 is hinged with a door 1014, and the front end of the door 1014 is also fixedly connected to a control panel 1015. The front end of the door 1014 is also fixedly connected to a handle 1016 and an air inlet slot 1017.

[0039] The mold temperature chamber 1 is opened via the handle 1016 through the front door 1014, which facilitates maintenance of the internal circulation module 3012 and the concentrator hood 201. The control panel 1015 displays parameters such as temperature in real time. It works with the air inlet slot 1017 to introduce cold air, which helps the radiator 2011 to form air convection, improving heat dissipation efficiency while facilitating real-time monitoring and adjustment by the operator.

[0040] During operation, the heat-gathering shroud 201 inside the mold temperature chamber 1 serves as the core for heat energy collection. Its frustum-shaped structure (thicker at the top and thinner at the bottom) utilizes fluid dynamics principles. When the top radiator 2011 (such as a fan or air pump) is activated, a negative pressure environment is created inside the mold temperature chamber 1. At this time, the hot air generated by the mold cooling inside the mold temperature chamber 1 is guided by the inner wall of the frustum and converges towards the top opening of the heat-gathering shroud 201, forming an accelerated airflow. The hot air enters the circulation pipe 301 of the water tank mechanism 3 through the exhaust pipe 2012 at the bottom of the heat-gathering shroud 201. The circulation pipe 301 adopts a spiral coil design to increase the contact area with the hot air. The cooling liquid (such as water or ethylene glycol solution) flowing inside the pipe absorbs heat from the hot air through the pipe wall, causing the hot air temperature to drop before being discharged from the rear end of the circulation pipe 301. During this process, the liquid temperature inside the water tank mechanism 3 rises, realizing the transfer of heat energy from exhaust gas to liquid and avoiding energy waste caused by direct discharge.

[0041] The water tank mechanism 3 injects room temperature cooling liquid through the liquid inlet pipe 3011. The liquid is transported to two circulation modules 3012 in the mold temperature chamber 1 through the supply pipe 3013. The circulation module 3012 is a flat metal cavity that fits tightly against the mold surface. When the high temperature mold comes into contact with the circulation module 3012, heat is conducted to the liquid in the cavity, causing the liquid temperature to rise. The heated waste liquid flows back to the water tank mechanism 3 through the discharge pipe 3015 and mixes with the liquid in the circulation pipe 301 that has risen due to absorbing the heat of the waste gas. The temperature of the mixed liquid is between the mold cooling requirement and the waste heat temperature of the waste gas. The power of the supply pump 3014 can be adjusted through the control panel 1015 to directly use some of the high temperature liquid for the mold that needs preheating, or mix with the room temperature liquid injected through the liquid inlet pipe 3011 and circulate again, forming an intelligent temperature control closed loop of "waste heat utilization + on-demand liquid supply".

[0042] Two support assemblies 101 at the bottom of the mold temperature chamber 1 are symmetrically distributed. Their support plate assemblies 1011 and mounting plates 1012 are fixed with bolts. Mounting holes 1013 can accommodate workbenches or frames of different sizes, ensuring stable operation of the equipment in high-frequency vibration environments. The chamber door 1014 is hinged to the front of the mold temperature chamber 1. The handle 1016 is ergonomically designed, allowing operators to quickly open the door 1014 to clean the seals of the circulation module 3012 and the dust accumulation on the inner wall of the flow collector 201. The control panel 1015 integrates… Temperature sensor and flow monitoring module display parameters such as temperature, liquid flow rate and heat recovery efficiency inside mold temperature chamber 1 in real time. Operators can switch between "energy saving mode" and "rapid cooling mode" through touch interface, and adjust the speed of radiator 2011 and the flow rate of supply pump 3014. Air inlet 1017 is set at the front of the chamber door 1014 and adopts a louvered structure, which can prevent foreign objects from entering while guiding cold air from the front of mold temperature chamber 1 to flow in and form convection with the hot air drawn out by radiator 2011, further improving heat dissipation efficiency.

[0043] A temperature sensor is installed at the connection between the circulation pipe 301 and the exhaust pipe 2012. When the exhaust gas temperature exceeds the set threshold, the control system automatically increases the liquid supply of the inlet pipe 3011. By increasing the circulation liquid flow rate, the hot air temperature is reduced, thus preventing high temperature from damaging the water tank mechanism 3. The discharge pipe 3015 has a built-in filter device that can trap metal debris or impurities in the waste liquid to prevent blockage of the circulation pipe. In addition, the inner wall of the flow hood 201 is coated with a high-temperature resistant coating, and both the exhaust pipe 2012 and the circulation pipe 301 are wrapped with heat insulation material to reduce heat loss during transmission and ensure maximum heat recovery efficiency.

[0044] In summary, this device can achieve rapid air intake operation through the air intake slot 1017.

[0045] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.
