Description

Auxiliary cooling molding device based on heat recovery Technical Field

[0001] This utility model relates to the field of molding device technology, and in particular to an auxiliary cooling molding device based on heat recovery. Background Technology

[0002] In industrial production, molding equipment, as a key piece of equipment for material forming and processing, is widely used in the large-scale production of products made of plastics, rubber, and composite materials. This equipment applies pressure to a mold and, in conjunction with temperature control, causes physical or chemical changes in the raw materials within a specific cavity, thereby forming a product with a predetermined shape and properties.

[0003] The mechanical structure of existing molding equipment mainly consists of a frame, mold assembly, heating components, and pressurizing mechanism. Its technical principle typically involves heating the mold with heating elements to bring the raw material to a molten or plastic state, and then applying pressure through hydraulic cylinders or mechanical transmission mechanisms to complete the molding process. In terms of heat management, traditional equipment mostly relies on natural heat conduction and radiation between the mold itself and the external environment for cooling.

[0004] However, existing molding equipment has significant shortcomings in heat management. Due to the lack of efficient heat recovery and active heat dissipation components, a large amount of heat generated by the mold during the production process is directly dissipated into the surrounding environment through natural convection and radiation. This not only leads to a large amount of energy waste and increases the production cost of enterprises, but also affects the working comfort of operators and the stability of equipment due to the increase in workshop ambient temperature. Therefore, an auxiliary cooling molding device based on heat recovery is proposed to solve the above problems. Summary of the Invention

The absorption component is used to collect the waste heat generated by the molding machine 1 and realize energy recovery through heat exchange. At the same time, it assists in cooling the mold and improves energy utilization efficiency.

[0035] The absorption assembly includes a suction fan 15, which is fixedly connected to the top of the molding machine 1 at its bottom. The suction fan 15, in conjunction with the filter box 3, performs a gas suction motion to efficiently recover the hot air generated during the molding process.

The connecting pipe 16, in conjunction with the heat exchanger 17, performs heat transfer motion, transferring heat to the heat exchange medium. The connecting pipe 16 connects the suction fan 15 and the heat exchanger 17, forming a complete heat recovery loop. One end of the connecting pipe 16 is fixedly connected to the heat exchanger 17. The heat exchanger 17, in conjunction with the heat transfer medium, performs heat exchange motion, realizing the reuse of heat energy. The heat exchanger 17 is used to transfer the heat from the exhaust gas to the working medium, improving the overall energy utilization rate. The bottom of the heat exchanger 17 is fixedly connected to the top of the base plate 2. The base plate 2, in conjunction with the heat exchanger 17, provides stable support motion, ensuring the safe operation of the equipment. The base plate 2 is used to fix all functional components and maintain the structural integrity of the components. The swing assembly includes multiple connecting blocks 11, which cooperate with the rotating bar 11. 2. Rotational motion is performed to drive the swing of the heat absorption cover 13. Connecting block 3 11 connects the swing mechanism to the heat absorption cover 13, transmitting mechanical motion. The bottom of each connecting block 3 11 is fixedly connected to the outer wall of the heat absorption cover 13. The outer wall of the heat absorption cover 13 cooperates with the connecting block 3 11 for fixed connection motion, ensuring stable swing transmission. Fixing plates 1 4 are fixedly connected to both sides of the filter box 3. Fixing plates 1 4 cooperate with fixing frames 1 5 to support the component movement and provide an installation base for the motor 6. Fixing plates 1 4 are used to reinforce the structure of the filter box 3 and withstand the reaction force of the swing component. Fixing frames 1 5 and 2 7 are fixedly connected to the opposite side of the two fixing plates 1 4. Fixing frames 1 5 and 2 7 cooperate to fix the motor 6, forming a double support for the motor 6.Fixed frame 5 and fixed frame 7 are used to distribute the operating load of motor 6 and improve the stability of the mechanism. Each fixed frame 5 has a motor 6 fixedly connected inside. The motor 6, in conjunction with connecting block 8, outputs power to drive the entire swing mechanism. Motor 6 provides the swing power source to ensure the continuous operation of the heat absorption cover 13. Each motor 6 output end is fixedly connected to connecting block 8. Connecting block 8, in conjunction with connecting block 9, performs a compound motion, converting rotation into swing. Connecting block 8 is used to convert the output motion form of motor 6, realizing non-circular motion transmission. Each connecting block 8 is located on the inner wall of fixed frame 7. The inner wall of fixed frame 7, in conjunction with connecting block 8, limits the movement and prevents the mechanism from dislodging. Each connecting block 8 has a rotatably connected connecting block 9 inside. Connecting block 9, in conjunction with the arc-shaped connecting plate 10, slides to form a specific trajectory swing. Connecting block 9 is used for motion form conversion, realizing the transition from rotation to cycloidal motion. Each fixed frame 7 has a rotatably connected connecting block 9 inside. There is a rotating bar 12, which works in conjunction with connecting block 3 11 to pivot, providing a pivot point for the swing of the heat absorber 13. The rotating bar 12 provides the center of rotation, ensuring accurate motion trajectory. The outer wall of each rotating bar 12 is fixedly connected to the inside of connecting block 3 11, which in turn works with the rotating bar 12 to form a stable rotation node. Each connecting block 3 11 has two fixedly connected arc-shaped connecting plates 10, which work with connecting block 2 9 to guide the movement and limit the swing angle. The arc-shaped connecting plates 10 provide a sliding track to control the maximum swing amplitude of the heat absorber 13. Each arc-shaped connecting plate 10 has an arc-shaped groove inside, which works with connecting block 2 9 to constrain the movement and precisely control the swing path. The arc-shaped groove is used for mechanical limiting to prevent overload. Connecting blocks 2 9 are slidably connected to the inner walls of adjacent arc-shaped grooves, and their inner walls slide relative to each other, achieving trajectory conversion.

[0036] Referring to Figures 4 and 5, the filter assembly is used to automatically remove impurities from hot air, maintain filtration efficiency, and reduce the need for manual maintenance. The filter assembly includes multiple filter screens 22, which rotate in conjunction with limiting rings 26 to achieve a self-cleaning function. The filter screens 22 are used to intercept solid particles in the hot airflow to ensure the safety of subsequent equipment. The multiple filter screens 22 are located inside the filter box 3, and the filter screens 22 are arranged in layers inside the filter box 3 to form a multi-stage filtration. A fixing plate 28 is fixedly connected to the inner wall of the filter box 3. The fixing plate 28, in conjunction with the limiting rings 26, supports the movement of the filter screens 22 and maintains the stable operation of the filter screens 22. The fixing plate 28 is used to fix the rotation axis of the filter screens 22 to prevent skewing. Each filter screen 22 is fixedly connected to the outer wall. Limiting ring 26, in conjunction with fixed plate 2 18, performs rotational limiting motion to ensure stable operation of filter screen 22. Limiting ring 26 is used for axial positioning to prevent radial movement of filter screen 22. Multiple limiting rings 26 are rotatably connected inside fixed plate 2 18, and the interior of fixed plate 2 18 precisely engages with the limiting rings 26 to reduce rotational friction. Multiple connecting brackets 19 are fixedly connected to the bottom of the inner wall of filter box 3. Connecting brackets 19 support the movement of rotating bar 21, providing an installation base for fan 20. Connecting brackets 19 maintain the verticality of rotating bar 21 to ensure transmission accuracy. Each connecting bracket 19 has a rotating bar 21 rotatably connected inside. Rotating bar 21 works in conjunction with fan 20 to convert airflow kinetic energy into mechanical energy. 21 is used to transmit rotational torque and drive the filter screen 22 to rotate. Each rotating bar 21 has a fan 20 fixedly connected to its outer wall. The fan 20, in conjunction with the hot airflow, performs passive rotational motion to achieve automatic energy conversion. The fan 20 senses the airflow speed and automatically adjusts the rotational speed of the filter screen 22. Each fan 20 is located at one end of the delivery hose 14. The outlet of the delivery hose 14, in conjunction with the fan 20, guides the airflow to optimize airflow distribution. One end of each rotating bar 21 extends through to the outside of the connecting frame 19 and is fixedly connected to a bevel gear 23. The bevel gear 23, in conjunction with a bevel gear 25, performs transmission motion to change the rotational axis. The bevel gear 23 is used for 90-degree power steering to adapt to spatial layout. Each filter screen 22 has a fixed connection on one side. The second bevel gear 25 meshes with the first bevel gear 23 to achieve self-driven rotation of the filter screen 22. The second bevel gear 25 is used to transmit driving torque, driving the filter screen 22 to centrifugally clean. Each second bevel gear 25 meshes with the first bevel gear 23, and the meshing surfaces of the bevel gears make precise movements to ensure transmission efficiency. Each second bevel gear 25 has a support plate 24 rotatably connected to its outer wall. The support plate 24 works with the second bevel gear 25 to provide auxiliary support and reduce bearing load. The support plate 24 is used to stabilize the transmission mechanism and prevent gear misalignment. The bottom of multiple support plates 24 is fixedly connected to the bottom of the inner wall of the filter box 3. The bottom of the inner wall of the filter box 3 is fixedly connected to the support plates 24 to form a stable support structure.

[0037] Working Principle: During the heat recovery process of the molding machine 1, the suction fan 15 is started. The airflow generated by the suction fan 15 drives the heat absorption cover 13 at one end of the conveying hose 14 through the filter box 3, absorbing the heat into the heat exchanger 17 at one end of the connecting pipe 16. The heat emitted by the mold is transferred to a specific medium, such as heat transfer oil or water. This heat-absorbing medium is then guided to other stages that require heat, such as preheating raw materials or heating the production workshop environment. At the same time, the medium can also carry away some of the heat from the mold during circulation, achieving an auxiliary cooling effect, thereby improving energy utilization efficiency and reducing production costs. Subsequently, the motor 6 is started, and the output end of the motor 6 drives... When connecting block 18 rotates, since connecting block 18 and connecting block 29 are rotatably connected, connecting block 29 will rotate around the output end of motor 6 and slide on the inner wall of the arc groove of the arc connecting plate 10. This will cause the heat absorption cover 13 on one side of connecting block 31 to swing back and forth around the rotating bar 12, thereby expanding the heat absorption range of the heat absorption cover 13 and ensuring that the heat generated by the mold is fully absorbed. This achieves the effect of good heat recovery and auxiliary cooling of the mold surface, solving the problem that traditional molding devices generate a lot of heat during use, which will naturally dissipate outward and easily cause resource waste. This enhances the efficiency of resource utilization.

[0038] During the filtration of impurities in the heat, after the heat is transferred to the inside of the filter box 3, the filter screen 22 filters out particulate impurities in the heat gas. The flow force of the gas drives the fan 20 to rotate. While the fan 20 is rotating, it drives the bevel gear 23 at one end of the rotating bar 21 to rotate. Since the bevel gear 23 meshes with the bevel gear 25, the rotational force of the bevel gear 23 is transmitted to the filter screen 22 through the bevel gear 25. The limiting ring 26 engages and rotates inside the fixing plate 18, causing the filter screen 22 to shift its position and preventing it from tilting. The centrifugal force generated by the rotation of the filter screen 22 throws out the impurities attached to the surface of the filter screen 22, achieving the filtration effect of impurities in the heat and preventing it from affecting the subsequent utilization of heat. Compared with traditional equipment, the heat recovery effect is greatly enhanced.
