Description

Technical Field

[0001] The invention relates to the technical field of heat dissipation fins, and in particular to a heat dissipation fin structure of a standard mold frame that is easy to dissipate heat. Background Art

[0002] Standard mold frames play a critical role in the operation of modern industrial molds, especially in the process of injection molding, stamping, etc., where a large amount of heat is continuously generated inside the mold due to physical changes and friction. Once there is a problem in the heat dissipation link, the heat cannot be evacuated in time. For metal mold frames, thermal expansion will be inevitable. This thermal expansion will cause the dimensional accuracy of the mold frame to exceed the tolerance range originally designed, and then directly have a negative impact on the matching mold clamping accuracy. The heat dissipation fin structure is undoubtedly the core of the mold frame heat dissipation system. Based on the basic scientific principles of heat conduction and convection, it successfully increases the contact area with the cooling medium through carefully planned specific structural design and ingenious layout, and comprehensively optimizes the process and mode of heat exchange. In this way, the heat accumulated inside the mold frame can be efficiently transferred to the external environment, effectively ensuring that the mold frame and mold system are always operating in a stable temperature environment. This not only maintains the high precision and high efficiency required for industrial production, but also closely fits the almost demanding requirements of modern manufacturing industry for product quality and production efficiency, laying a solid foundation for the stability and development of industrial production.

[0003] The internal flow channel of the existing mold frame heat dissipation fin is a simple straight channel. Although this straight channel shape is easy to process, the contact mode between the cooling medium and the flow channel wall is relatively simple during the heat exchange process. Water is easy to form laminar flow and produce boundary layer in the straight channel, which limits the rapid transfer of heat to the entire water body. In addition, due to the laminar flow, a temperature gradient is formed in the cross section of the channel. The heat exchange driving force is weakened with the heat transfer, affecting the heat dissipation performance and reliability. At the same time, water quality factors cause scale to easily deposit on the flow channel wall, and the straight channel structure is not conducive to scale discharge and cleaning, thereby increasing thermal resistance and reducing water flow, making it difficult to meet the efficient heat dissipation needs of modern mold frames. Summary of the invention

[0004] In order to solve the technical problems raised in the above-mentioned background technology, the present invention provides a standard mold frame heat dissipation fin structure that is easy to dissipate heat. The advantages thereof are: through the setting of the heat dissipation component, water can continuously circulate between the fin bodies, so that heat can be more fully transferred in a smaller space. Compared with the traditional unidirectional water flow, the circulating water flow can pass through the surface of the fin body multiple times, which increases the contact time and frequency of water and the fin body, and improves the heat dissipation effect of the mold frame.

[0005] In order to achieve the above object, the present invention specifically adopts the following technical solutions: The heat dissipation fin structure of the standard mold frame for easy heat dissipation includes a sealing box and a mold frame body. The number of the sealing boxes is set to two, and the two sealing boxes are respectively located on both sides of the mold frame body. A heat dissipation component is arranged inside each sealing box; There are two groups of heat dissipation components, both used to dissipate heat when the mold frame body is working. Each group of heat dissipation components includes a base, and a plurality of fin bodies are arranged on the top of the base. A plurality of through holes are arranged on the top of each fin body, wherein the apertures of some of the through holes increase from left to right along the horizontal direction of the fin body, and the apertures of other through holes decrease from left to right along the horizontal direction of the fin body.

[0006] Through the above technical solution: the heat dissipation component allows water to circulate continuously between the fin bodies, allowing heat to be more fully transferred in a smaller space. Compared with the traditional one-way water flow, the circulating water flow can pass through the surface of the fin body multiple times, increasing the contact time and frequency of water and the fin body, and improving the heat dissipation effect of the mold frame.

[0007] The present invention is further configured such that a heat dissipation cavity is provided inside each of the two sealed boxes, and each heat dissipation component is located inside a corresponding heat dissipation cavity.

[0008] The present invention is further configured such that one end of the two sealing boxes is connected to a water inlet pipe, one end of the two sealing boxes away from the water inlet pipe is connected to a water outlet pipe, and a valve is provided inside the water inlet pipe.

[0009] Through the above technical solution: the external driving device drives water into the heat dissipation cavity of the sealing box from the water inlet pipe. Since the water inlet pipe is provided with a valve, the flow rate and flow velocity of the water can be controlled.

[0010] The present invention is further configured such that the tops of the two sealing boxes are both provided with fixing blocks, and the interiors of the two fixing blocks are both provided with cleaning components.

[0011] The present invention is further configured such that two groups of cleaning components are provided, each group of cleaning components includes a fixed plate, the fixed plate is located inside the fixed block, the bottom of the fixed plate is fixedly connected to the cleaning plate, a plurality of dust suction holes are opened inside the cleaning plate, and the plurality of dust suction holes are all connected to the fixed plate.

[0012] The present invention is further configured such that each cleaning assembly also includes a vacuum cleaner, which is located on one side of the mold frame body. Both ends of the vacuum cleaner are connected with connecting pipes, and one of the connecting pipes is connected to the fixed plate.

[0013] The present invention is further configured such that fixed seats are provided on both sides of the mold frame body, electric cylinders are provided inside the two fixed seats, the output ends of the two electric cylinders extend through the interior of the fixed blocks and are fixedly connected to the corresponding fixed plates respectively, the two fixed blocks are respectively connected to the corresponding heat dissipation cavities, and the two fixed plates are respectively slidably connected to the corresponding heat dissipation cavities.

[0014] Through the above technical solution: the combination of scraping and vacuuming in the cleaning component can ensure the efficiency and thoroughness of the cleaning process. The scraping action can remove the impurities that are stubbornly attached to the surface of the fin body, while the vacuuming can clean these impurities in time to prevent them from floating again or reattaching to the fin body. During the cleaning process, the running speed and stroke of the electric cylinder need to be controlled so that its running speed is not too fast to avoid unnecessary collision or damage to the cleaning plate and the fin body, so as to achieve the cleaning of the fin body.

[0015] The present invention is further configured such that sealing plates are slidably connected to the interiors of the two sealing boxes, and the two sealing plates are respectively located between the corresponding cleaning plates and the fin bodies.

[0016] Through the above technical solution: after cleaning, the sealing plate is installed on the sealing box, because there is a friction groove between the sealing box and the sealing plate, the friction groove between the sealing box and the sealing plate can make the contact between the two closer. When the sealing plate is installed on the sealing box, the friction groove will generate friction, and this friction force makes the contact surface of the sealing plate and the sealing box fit together better.

[0017] The beneficial effects of the present invention are: 1. The present invention arranges the heat dissipation assembly so that water circulates continuously between the fin bodies, allowing heat to be more fully transferred in a smaller space. Compared with the traditional one-way water flow, the circulating water flow can pass through the surface of the fin body multiple times, increasing the contact time and frequency between the water and the fin body, and improving the heat dissipation effect of the mold frame.

[0018] 2. The present invention can reach deep into the heat dissipation cavity of the sealing box to clean the fin body through the cleaning component, and the dust suction hole can absorb dust, debris and other impurities attached to the surface of the fin body and the heat dissipation cavity, thereby avoiding the accumulation of impurities that affect the heat dissipation efficiency of the fin body, ensuring the cleanliness of the surface of the fin body, and maintaining good heat dissipation performance.

DETAILED DESCRIPTION

[0021] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0022] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0023] Reference Figure 1-Figure 8 The heat dissipation fin structure of the standard mold frame for easy heat dissipation includes a sealing box 1 and a mold frame body 2. The number of the sealing boxes 1 is set to two. The two sealing boxes 1 are respectively located on both sides of the mold frame body 2. A heat dissipation component is arranged inside each sealing box 1. There are two groups of heat dissipation components, both used for dissipating heat when the mold frame body 2 is working. Each group of heat dissipation components includes a base 5, and a plurality of fin bodies 6 are provided on the top of the base 5. A plurality of through holes 7 are provided on the top of each fin body 6. The apertures of some of the through holes 7 increase from left to right along the horizontal direction of the fin body 6, and the apertures of other through holes 7 decrease from left to right along the horizontal direction of the fin body 6.

[0024] Reference Figure 1-Figure 6 A heat dissipation cavity 4 is provided inside the two sealed boxes 1, and each heat dissipation component is located inside the corresponding heat dissipation cavity 4. One end of the two sealed boxes 1 is connected to a water inlet pipe 3, and the ends of the two sealed boxes 1 away from the water inlet pipe 3 are connected to a water outlet pipe 8, and a valve is provided inside the water inlet pipe 3.

[0025] When the mold frame body 2 generates heat during operation, the heat will be conducted to the sealing box 1 and the heat dissipation components inside it. Water is introduced into the heat dissipation cavity 4 of the sealing box 1 from the water inlet pipe 3 through an external drive device. Since the water inlet pipe 3 is provided with a valve, the flow rate and flow velocity of the water can be controlled. When the water flows in the heat dissipation cavity 4, it will be in full contact with the fin body 6. The aperture of a part of the through holes 7 on the fin body 6 increases from left to right in the horizontal direction, and the other part decreases from left to right. This design makes the water flow produce different flow rates and pressure changes when it flows through the fin body 6, forming a relatively complex water flow path and turbulence effect, thereby enhancing the heat exchange efficiency between the water and the fin body 6. After the water absorbs the heat of the fin body 6, the temperature rises, and then flows out from the water outlet pipe 8, thereby taking out the heat of the mold frame body 2 and achieving the purpose of circulating heat dissipation.

[0026] Because there is a fin body 6 whose aperture of a through hole 7 decreases from left to right along the horizontal direction between every two through holes 7 whose aperture increases from left to right along the horizontal direction of the fin body 6, and because water flows more easily from the area with a larger aperture, and when water flows from the area with a smaller aperture to the area with a larger aperture, a local microcirculation is formed between the two fin bodies 6. In this microcirculation, water circulates continuously between the different aperture areas of the two fin bodies 6. This circulating flow is similar to a small convection system, forming a relatively independent water flow path in the narrow space between the fins.

[0027] The through hole 7 provided on the fin body 6 may also be Figure 8 As shown, the effect described above can also be achieved.

[0028] By setting the heat dissipation component, water circulates continuously between the fin bodies 6, allowing heat to be more fully transferred in a smaller space. Compared with the traditional one-way water flow, the circulating water flow can pass through the surface of the fin body 6 multiple times, increasing the time and frequency of contact between the water and the fin body 6, and improving the heat dissipation effect of the mold frame.

[0029] Reference Figure 6-Figure 7 A fixing block 9 is provided on the top of each of the two sealing boxes 1, and a cleaning assembly is provided inside each of the two fixing blocks 9. There are two groups of cleaning assemblies, and each group of cleaning assemblies includes a fixing plate 13, which is located inside the fixing block 9. A cleaning plate 16 is fixedly connected to the bottom of the fixing plate 13, and a plurality of dust suction holes 17 are provided inside the cleaning plate 16. The plurality of dust suction holes 17 are all connected to the fixing plate 13. Each group of cleaning assemblies also includes a vacuum cleaner 14, which is located on one side of the mold frame body 2. Connecting pipes 15 are provided at both ends of the vacuum cleaner 14, and one of the connecting pipes 15 is connected to the fixing plate 13.

[0030] After a period of use, when the fin body 6 in the heat dissipation cavity 4 needs to be cleaned, the cooling medium in the sealing box 1 is first discharged, and then the sealing plate 12 is pulled out to prevent the sealing plate 12 from causing obstacles to the running track of the fixed plate 13, and then the electric cylinder 10 is started, and the output end of the electric cylinder 10 pushes the fixed plate 13 to move along the fixed block 9 into the heat dissipation cavity 4, thereby driving the cleaning plate 16 to enter the heat dissipation cavity 4 to scrape the impurities on the outer wall of the fin body 6. When the cleaning plate 16 enters the heat dissipation cavity 4 and scrapes the impurities on the outer wall of the fin body 6, the vacuum cleaner 14 is started. The vacuum cleaner 14 generates suction, so that the scraped impurities can be quickly sucked into the channel inside the fixed plate 13 through the dust suction holes 17 on the cleaning plate 16, and then collected into the external dust collection container (not shown) equipped with the vacuum cleaner 14 through the connecting pipe 15. This scraping and dust collection method can ensure the efficiency and thoroughness of the cleaning process. The scraping action can peel off the impurities that are more stubbornly attached to the surface of the fin body 6, and the vacuuming can clean up these impurities in time to prevent them from floating again or re-attaching to the fin body 6. During the cleaning process, the running speed and stroke of the electric cylinder 10 need to be controlled so that its running speed is not too fast to avoid unnecessary collision or damage to the cleaning plate 16 and the fin body 6, thereby achieving the cleaning of the fin body 6.

[0031] The cleaning component can penetrate into the heat dissipation cavity 4 of the sealing box 1 to clean the fin body 6, and the dust suction hole 17 can absorb dust, debris and other impurities attached to the surface of the fin body 6 and the heat dissipation cavity 4, thereby avoiding the accumulation of impurities affecting the heat dissipation efficiency of the fin body 6, ensuring the cleanliness of the surface of the fin body 6, and maintaining good heat dissipation performance.

[0032] Reference Figure 6-Figure 7 A fixed seat 11 is provided on both sides of the mold frame body 2, and an electric cylinder 10 is provided inside the two fixed seats 11. The output ends of the two electric cylinders 10 extend through the interior of the fixed block 9 and are fixedly connected with the corresponding fixed plates 13 respectively. The two fixed blocks 9 are respectively connected with the corresponding heat dissipation cavity 4, and the two fixed plates 13 are respectively slidably connected with the corresponding heat dissipation cavity 4. The interiors of the two sealing boxes 1 are slidably connected with sealing plates 12, and the two sealing plates 12 are respectively located between the corresponding cleaning plates 16 and the fin body 6.

[0033] After cleaning, the sealing plate 12 is installed on the sealing box 1, and the heat dissipation operation is continued, because there is a friction groove (which is a prior art and not shown in the figure) between the sealing box 1 and the sealing plate 12, and the friction groove between the sealing box 1 and the sealing plate 12 can make the contact between the two closer. When the sealing plate 12 is installed on the sealing box 1, the friction groove will generate friction, and this friction force makes the contact surface of the sealing plate 12 and the sealing box 1 fit together better.

[0034] For example, during the actual installation process, the friction groove can prevent the sealing plate 12 from shifting due to external vibrations or internal pressure changes, ensuring that the sealing plate 12 is always in the correct position, thereby effectively sealing the heat dissipation cavity 4, and its close fit can prevent the cooling medium from leaking or external impurities from entering.

[0035] Working principle: During the operation of the mold frame body 2, heat is inevitably generated, and this heat will be quickly transferred to the sealing box 1 on both sides thereof and the internal heat dissipation components. At this time, water is driven from the water inlet pipe 3 into the heat dissipation cavity 4 of the sealing box 1 through an external driving device. Since the water inlet pipe 3 is provided with a valve, the flow rate and flow velocity of the water can be controlled. When the water flows in the heat dissipation cavity 4, it will be in full contact with the fin body 6.

[0036] The core component of the heat dissipation assembly, the fin body 6, is designed so that the aperture of a portion of the through holes 7 on its top increases horizontally from left to right, while the other portion decreases horizontally from left to right, so that when the water flows through the fin body 6, the flow velocity and pressure undergo complex changes, forming a water flow path and turbulence effect. At the level of a single fin body 6, the turbulence effectively destroys the thermal boundary layer formed between the water and the fin surface, greatly enhancing the heat exchange efficiency. At the same time, due to the difference in the aperture of adjacent through holes 7, water forms a local microcirculation between the two fin bodies 6, forming a small convection system. This microcirculation enables heat to be fully transferred in a smaller space. The circulating water flows repeatedly through the surface of the fin body 6, significantly increasing the contact time and frequency between the water and the fin body 6, thereby greatly improving the heat dissipation effect of the entire mold frame.

[0037] After long-term use, in order to ensure the continued high efficiency of the heat dissipation system, the cleaning component begins to play a role. When it is necessary to clean the fin body 6, the cooling medium in the sealing box 1 must first be completely emptied, and the sealing plate 12 must be pulled out to make room for the cleaning operation. Then start the electric cylinder 10, which pushes the fixed plate 13 to move slowly along the fixed block 9 into the heat dissipation cavity 4, thereby driving the cleaning plate 16 to go deep into it. In the process of entering the heat dissipation cavity 4, the cleaning plate 16 will scrape off the impurities attached to the outer wall of the fin body 6. At the same time, the vacuum cleaner 14 is started synchronously, and its suction force quickly sucks the scraped impurities into the external dust collection container through the dust suction hole 17, the channel inside the fixed plate 13, and the connecting pipe 15. This method of closely combining scraping and dust collection ensures that the cleaning process is both efficient and thorough, effectively avoids the adverse effects of impurity accumulation on the heat dissipation efficiency of the fin body 6, always maintains the cleanliness of the surface of the fin body 6, and ensures good heat dissipation performance.

[0038] After the cleaning work is completed, the sealing plate 12 with the friction groove is installed back on the sealing box 1 to continue the heat dissipation operation. When the sealing plate 12 is installed in place, the friction groove can generate just the right friction force, so that the contact surface of the sealing plate 12 and the sealing box 1 fits tightly together. In the actual installation scenario, the friction groove can effectively prevent the sealing plate 12 from shifting due to external vibration interference or fluctuations in internal pressure, ensuring that the sealing plate 12 is always in a precise and correct position, thereby reliably sealing the heat dissipation cavity 4, preventing the leakage of the cooling medium and the intrusion of external impurities, and providing a solid and powerful guarantee for the stable and efficient operation of the entire mold frame heat dissipation system.

Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
