Description

Technical Field

[0001] This invention relates to the field of injection molding equipment technology, and in particular to an injection molding device for the side plate of a synchronous belt pulley in an intelligent equipment for a photovoltaic module production line. Background Technology

[0002] With the rapid development of the photovoltaic industry, the production efficiency and quality of photovoltaic modules have become the focus of industry attention. As an important component in the photovoltaic module production line, the quality and production efficiency of the synchronous belt pulley side plate directly affect the stability and capacity of the entire production line. The synchronous belt pulley side plate is usually manufactured by injection molding, but this method has many defects in the production of synchronous belt pulley side plates, which has a direct impact on the actual application of synchronous belt pulley side plates.

[0003] Due to gaps created during mold closing during injection molding or other reasons, the surface of the injection-molded product has many burrs. This not only affects the appearance quality of the product but also causes inconvenience to the subsequent assembly process of the synchronous belt pulley side plate. Furthermore, excess material in the mold during injection molding will be absorbed into the mold surface through the gaps. If waste material remains on the mold's mating surface during the next mold closing production, it will adversely affect the accuracy of mold closing, thus affecting the molding precision and quality of the product. At the same time, the demolding process of the molded product is extremely difficult because the molded product is relatively delicate and is usually embedded in the mold. If manual demolding is used, it is very easy to cause damage. Therefore, the entire process from injection molding to removal of the molded product is time-consuming. In addition, the instability of manual operation will also affect the product quality and production efficiency. Summary of the Invention

[0004] The technical problem to be solved by the present invention is that the existing technology has the disadvantages of difficult removal of production waste and difficult removal of molded parts. To this end, we propose an injection molding device for the side plate of the synchronous belt pulley of the intelligent equipment of photovoltaic module production line.

[0005] To achieve the above objectives, this application adopts the following technical solution: an injection molding device for a synchronous pulley side plate of a photovoltaic module production line intelligent equipment, comprising a lower mold, an injection molding device body installed on the top of the lower mold, two hydraulic rods fixedly connected to the middle of the injection molding device body, an upper mold fixedly connected to the output end of the hydraulic rods, extension plates fixedly connected to both sides of the bottom of the injection molding device body, and support plates fixedly connected to both sides of the top of the lower mold; the injection molding device for a synchronous pulley side plate of a photovoltaic module production line intelligent equipment further includes a scraper and a mold module; The bottom of the extension plate is equipped with a transmission component so that the scraper moves back and forth along the surface of the lower mold as the injection molding device body rises and falls, and moves left and right repeatedly while the scraper moves horizontally, so that the scraper scrapes the waste material on the surface of the lower mold during the movement, and the scraper can move left and right back and forth to enhance the scraping effect on stubborn dirt. The demolding assembly is connected to the injection molding device body for transmission. After the injection molding device body rises to a designated position, it drives the mold module to move upward, so that the mold module is lifted out of the lower mold and the molded product in the lower mold is ejected upward.

[0006] Preferably, the transmission assembly includes: An inclined plate is fixedly connected to both sides of the upper mold. An L-shaped plate is rotatably connected to the bottom of the extension plate, and a connecting rod is rotatably connected to the top of the L-shaped plate. The end of the connecting rod away from the L-shaped plate is rotatably connected to the bottom of the inclined plate. A sliding groove is formed at the bottom of the L-shaped plate. A long groove is formed on the surface of the support plate. A sliding rod is slidably connected to the inner wall of the long groove. A long rod is slidably connected to the inner walls of the two sliding grooves. The bottom of the long rod is fixedly connected to the sliding rod. A scraper is fixedly connected to the surface of the long rod. A slot is formed at the top of the lower mold, and a waste box is embedded in the inner wall of the slot.

[0007] Preferably, the demolding assembly includes: A right-angle plate is fixedly connected to both sides of the mold module. A circular groove is provided on the top of the lower mold. Limiting grooves are provided on both sides of the lower mold. The right-angle plate is slidably connected to the inner wall of the limiting groove. A lifting groove is provided on the surface of the right-angle plate. Irregularly shaped plates are fixedly connected to both sides of the upper mold. The bottom of the irregularly shaped plates is slidably connected to the inner wall of the lifting groove.

[0008] Preferably, a vertical arc-shaped plate is fixedly connected to the top of the long rod, and guide plates are fixedly connected to both sides of the top of the lower mold.

[0009] Preferably, a fan is fixedly connected to one side of the lower mold, the output end of the fan faces the top of the lower mold, and the fan is installed at an angle on one side of the lower mold.

[0010] Preferably, the inner wall of the long groove has a wavy structure, and the surface of the slide rod is adapted to the inner diameter of the long groove.

[0011] Preferably, the right-angled end of the L-shaped plate rotates with the bottom of the extension plate as the center.

[0012] Preferably, the inner diameter of the lifting groove is greater than the length of the irregular plate, and the bottom of the irregular plate abuts against the surface of the bottom of the lifting groove.

[0013] The technical effects and advantages of this invention are as follows: 1. In this invention, after injection molding is completed when the upper mold rises, the L-shaped plate drives the scraper to move horizontally against the surface of the lower mold. This allows the scraper to remove burrs from the surface of the lower mold and the surface of the molded part. At the same time, the scraper moves left and right to increase its scraping effect on waste material. Removing burrs from the surface of the molded part ensures molding quality and prevents waste material from accumulating on the surface of the lower mold, which could affect the next mold closing production of this device.

[0014] 2. In this invention, the upper mold moves upward and reaches a certain height, which drives the mold module to be lifted from inside the circular groove. This causes the mold module to push the injection molded part formed inside the lower mold upward. This process effectively avoids the problem that the product is embedded inside the lower mold after molding, which would damage the molded product when it is manually removed, or that the product is difficult to remove because it is embedded too tightly.

[0017] The present invention will now be described in further detail with reference to the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the invention in a schematic manner, and therefore only show the components relevant to the invention.

[0018] Reference Figures 1-6As shown, the present invention provides an injection molding device for the side plate of the synchronous belt pulley of the intelligent equipment of the photovoltaic module production line, including a lower mold 1, an injection molding device body 2 installed on the top of the lower mold 1, two hydraulic rods 3 fixedly connected to the middle of the injection molding device body 2, an upper mold 4 fixedly connected to the output end of the hydraulic rods 3, extension plates 5 fixedly connected to both sides of the bottom of the injection molding device body 2, and support plates 6 fixedly connected to both sides of the top of the lower mold 1. The injection molding device for the side plate of the synchronous belt pulley of the intelligent equipment of the photovoltaic module production line also includes a scraper 7 and a mold module 8. The bottom of the extension plate 5 is equipped with a transmission component so that the scraper 7 moves back and forth along the surface of the lower mold 1 as the injection molding device body 2 rises and falls, and moves left and right repeatedly while the scraper 7 moves horizontally, so that the scraper 7 scrapes the waste material on the surface of the lower mold 1 during the movement, and the scraper 7 can move left and right back and forth to enhance the scraping effect on stubborn dirt. The demolding assembly is connected to the injection molding device body 2 via a transmission. After the injection molding device body 2 rises to a designated position, it drives the mold module 8 to move upward, causing the mold module 8 to be lifted upward from inside the lower mold 1. This ejects the molded product from the lower mold 1. When the lower mold 1 separates from the upper mold 4, the scraper 7 automatically removes burrs from the surface of the lower mold 1 and the surface of the molded product, preventing the injection overflow from sticking to the surface of the lower mold 1 and affecting the next mold closing production. At the same time, after the scraper 7 has finished cleaning, the mold module 8 can automatically rise to eject the finished product from inside the lower mold 1, thus completing the demolding process. This facilitates the demolding of the molded product, while automatic cleaning ensures product quality.

[0019] Reference Figures 1-6 As shown in this embodiment, the transmission assembly includes: Inclined plate 9 is fixedly connected to both sides of the upper mold 4. An L-shaped plate 10 is rotatably connected to the bottom of the extension plate 5. A connecting rod 11 is rotatably connected to the top of the L-shaped plate 10. The end of the connecting rod 11 furthest from the L-shaped plate 10 is rotatably connected to the bottom of the inclined plate 9. A groove 12 is provided at the bottom of the L-shaped plate 10. A long groove 14 is provided on the surface of the support plate 6. A sliding rod 15 is slidably connected to the inner wall of the long groove 14. A long rod 16 is slidably connected to the inner walls of the two grooves 12. The bottom of the long rod 16 is fixedly connected to the sliding rod 15. A scraper 7 is fixedly connected to the surface of the long rod 16. A slot 17 is provided at the top of the lower mold 1. The inner wall of the slot 17 is embedded... The device has a waste box 18. The right-angle end of the L-shaped plate 10 rotates around the bottom of the extension plate 5. The device uses the extension and retraction of the hydraulic rod 3 to drive the upper mold 4 to approach the lower mold 1 for mold closing. Then, the hydraulic rod 3 introduces injection molding material into the upper mold 4. The hot-melt material cools in the complete mold formed by the lower mold 1 and the upper mold 4 to form the synchronous belt pulley side plate of the photovoltaic module production line intelligent equipment. Afterwards, the hydraulic rod 3 drives the upper mold 4 to rise, causing the lower mold 1 to separate from the upper mold 4. The formed product is then manually removed, thus completing one production of the synchronous belt pulley side plate. During this process, when the lower mold 1 separates from the upper mold 4, the device will be in a state of... Figure 1 In the middle form, when the upper mold 4 moves down and closes with the lower mold 1 under the action of the hydraulic rod 3, the inclined plate 9 also moves down with the upper mold 4. The position of the extension plate 5 is always fixed. When the inclined plate 9 moves down with the upper mold 4, it pulls the connecting rod 11, so that the end of the connecting rod 11 connected to the L-shaped plate 10 gradually forms a curved state. During the process, the L-shaped plate 10 rotates at the bottom of the extension plate 5 with the rotation angle of the connecting rod 11. When the connecting rod 11 pulls the top of the L-shaped plate 10 and it is curved, the bottom of the L-shaped plate 10 will rotate along the extension plate 5 as the center, turning the bottom end of the L-shaped plate 10 to the other side of the lower mold 1. At the same time, the long rod 16 slides inside the slide groove 12 and moves with the L-shaped plate 10. This makes the position of the scraper 7 also turn to the other side of the lower mold 1. At this time, the lower mold 1 and the upper mold 4 will complete the mold closing. After injection molding is completed, the upper mold 4 rises away from the lower mold 1. During this process, the inclined plate 9 moves upward to reset, driving the L-shaped plate 10 and the connecting rod 11 back to their initial state. This causes the bottom end of the L-shaped plate 10 to rotate to the other side of the lower mold 1. At this time, the lower mold 1 separates from the upper mold 4, and the finished product is exposed. When the L-shaped plate 10 resets to the other side, the long rod 16 slides inside the slide groove 12 and moves with the L-shaped plate 10. This causes the long rod 16 to flatten at the top of the lower mold 1. The scraper 7 is moved so that it adheres to the surface of the lower mold 1, removing burrs from the exposed injection-molded surface and scraping away excess material generated during injection on the surface of the lower mold 1. While the long rod 16 is in its normal position, the sliding rod 15 is restricted to sliding along the inner wall of the long groove 14. This causes the sliding rod 15 to move along the inner wall of the long groove 14 when the long rod 16 moves horizontally. Since the inner wall of the long groove 14 is wavy, the sliding rod 15 will move in a wavy pattern along the inner wall of the long groove 14, thereby causing the long rod 16 to move repeatedly left and right. The long rod 16 can move left and right repeatedly on the inner wall of the slide 12. At the same time, the long rod 16 will adjust its position on the inner wall of the slide 12 according to the rotation angle of the L-shaped plate 10, so as to ensure that it moves with the L-shaped plate 10. This process will allow the long rod 16 to move left and right repeatedly while moving horizontally, thereby driving the scraper 7 to move horizontally and scrape on the surface of the lower mold 1. At the same time, it will push the waste material to the waste box 18 and scrape the waste material into the waste box 18 for collection. Meanwhile, the scraper 7 will move left and right to perform friction scraping, so that when scraping the burrs on the surface of the lower mold 1 and the surface of the finished product, the scraper 7 has a sawing-like cutting force, which can move horizontally and cut repeatedly, thereby improving the scraping effect of the scraper 7 on the waste material and the finished product burrs. It can effectively scrape away stubborn and tough waste material, ensuring the cleanliness of the injection molded finished product of this device, avoiding the impact of overflow waste material generated during injection molding on the next mold closing production, and facilitating the removal of burrs generated in the merging gap of the synchronous belt pulley side plate after production. Finally, the scraper 7 moves upward with the upper mold 4 and is moved to the initial state through the transmission component, completing one injection molding production. When the lower mold 1 and the upper mold 4 are closed for the next production, the above operation process will continue to clean the waste generated by the operation of this device. Each operation of this device can drive the scraper 7 to remove waste from the lower mold 1 and the surface of the finished product, ensuring the molding quality of the injection molded parts and avoiding the accumulation of waste that may affect the next mold closing production of this device.

[0020] Reference Figure 1 , Figure 2 , Figure 3 and Figure 6 As shown in this embodiment, the demolding component includes: A right-angle plate 19 is fixedly connected to both sides of the mold module 8. A circular groove 20 is provided on the top of the lower mold 1, and limit grooves 21 are provided on both sides of the lower mold 1. The right-angle plate 19 is slidably connected to the inner wall of the limit grooves 21. A lifting groove 22 is provided on the surface of the right-angle plate 19. Irregularly shaped plates 23 are fixedly connected to both sides of the upper mold 4. The bottom of the irregularly shaped plates 23 is slidably connected to the inner wall of the lifting grooves 22. The inner diameter of the lifting grooves 22 is greater than the length of the irregularly shaped plates 23. The bottom of the irregularly shaped plates 23 abuts against the surface of the bottom of the lifting grooves 22. When the upper mold 4 moves down to close with the lower mold 1, the irregularly shaped plates 23... The shaped plate 23 will slide along the inner wall of the lifting groove 22. When the upper mold 4 moves down to a certain position, the shaped plate 23 will slide to the bottom of the inner wall of the lifting groove 22. At the same time, the bottom of the shaped plate 23 will press down on the right-angle plate 19, causing the right-angle plate 19 to move downward and push it into the bottom of the inner wall of the limiting groove 21. This will also drive the mold module 8 to reset to the middle of the inner wall of the lower mold 1, so that the mold module 8 and the inner wall of the lower mold 1 form a complete lower mold groove. After injection molding, the upper mold 4 will gradually rise and drive the shaped plate 23 to reset, so that the shaped plate 23 first moves along the lifting groove 22 towards the bottom of the lower mold 1. The upper mold 4 slides upwards. After sliding to the bottom of the inner wall of the lifting groove 22, the right-angle plate 19 is pulled upwards, causing it to rise along the inner wall of the limiting groove 21. At the same time, the right-angle plate 19 drives the mold module 8 to move upwards from the circular groove 20, causing the mold module 8 to push the injection molded product embedded in the inner wall of the lower mold 1 molding groove upwards, thereby completing the demolding process of the product on the inner wall of the lower mold 1. During the process, the irregular plate 23 will first slide upwards along the lifting groove 22, so that when the upper mold 4 rises, it will not initially drive the mold module 8 to move upwards. Only when the upper mold 4 is about to move to the top will it drive the mold module 8 to eject the injection molded product. This ensures that the L-shaped plate 10 can move the scraper 7 on the surface of the lower mold 1 without affecting the movement of the scraper 7. At the same time, when the upper mold 4 descends, the inner wall of the lifting groove 22 is no longer constrained by the irregular plate 23 and will naturally fall back into the circular groove 20 due to the gravity of the mold module 8 and the right-angle plate 19. This allows the mold module 8 to automatically eject the molded product after injection molding and cleaning with the scraper 7, so that the operator can take out the molded product from the lower mold 1. This avoids the problem of damaging the molded product when it is manually removed because it is embedded in the lower mold 1, or the problem of removing the product because it is embedded too tightly.

[0021] Reference Figure 5 and Figure 6As shown in this embodiment: a vertical arc-shaped plate 24 is fixedly connected to the top of the long rod 16, and guide plates 25 are fixedly connected to both sides of the top of the lower mold 1. With the vertical arc-shaped plate 24 positioned at the top of the long rod 16, when the scraper 7 removes burrs from the surface of the lower mold 1 or the finished product, the waste material slides along the surface of the scraper 7 towards the long rod 16. At this time, the waste material is restricted by the arc-shaped guide of the vertical arc-shaped plate 24. After accumulating on the surface of the scraper 7, the waste material gradually guides to one side of the scraper 7 along the arc of the surface of the vertical arc-shaped plate 24, thereby preventing the waste material from being scraped away. After being removed, the waste material slides along the surface of the scraper 7 to the other side of the scraper 7, while remaining on the surface of the lower mold 1. Then, the scraper 7 and the vertical arc plate 24 push the waste material to the edge of the lower mold 1. The waste material will gradually fall into the waste box 18 along the surface of the guide plate 25 and follow the arc of the guide plate 25 for collection. Through the arc-shaped guiding structure of the guide plate 25 and the vertical arc plate 24, it is ensured that the waste material can be accurately collected into the waste box 18, avoiding the problem that the waste material is difficult to clean when it is scraped and pushed by the scraper 7 and falls across the surface of the scraper 7 onto the surface of the lower mold 1.

[0022] Reference Figures 1-3 As shown in this embodiment: a fan 13 is fixedly connected to one side of the lower mold 1. The output end of the fan 13 faces the top of the lower mold 1, and the fan 13 is installed at an angle on one side of the lower mold 1. Due to the angled installation of the fan 13 and the airflow direction of the fan 13 facing the waste box 18, the wind force generated by the fan 13 can blow the waste material on the surface of the lower mold 1 towards the waste box 18. The wind force generated by the fan 13 can blow away the small waste materials and dirt remaining on the surface of the lower mold 1, further ensuring the cleanliness of the injection molding process. At the same time, the operation of the fan 13 can deliver natural air to the surfaces of the lower mold 1 and the upper mold 4, thereby accelerating the cooling speed of the mold and the molded part, which is more conducive to the demolding of the finished product and improves the efficiency of the injection molding process of this device.

[0023] Reference Figure 5 As shown in this embodiment: the inner wall of the long groove 14 has a wavy structure, and the surface of the slide rod 15 is adapted to the inner diameter of the long groove 14. The slide rod 15 slides along the inner wall of the long groove 14. At the same time, the slide rod 15 is I-shaped. While it can slide along the inner wall of the long groove 14, the top and bottom positions are limited by the height of the fan 13, so that the long rod 16 will not cause the scraper 7 to have gaps from the surface of the lower mold 1 due to sliding inside the groove 12. Through the connection between the slide rod 15 and the long groove 14, the position of the long rod 16 and the scraper 7 is restricted, ensuring that the scraper 7 and the lower mold 1 maintain a close distance to ensure the stable operation of the device.

[0024] Working Principle: This device uses the extension and retraction of hydraulic rod 3 to move the upper mold 4 closer to the lower mold 1 for mold closing. Then, hydraulic rod 3 introduces injection molding material into the upper mold 4. The hot-melt material cools within the complete mold formed by the lower mold 1 and the upper mold 4, forming the side plate of the synchronous belt pulley in the intelligent equipment of the photovoltaic module production line. Afterwards, hydraulic rod 3 drives the upper mold 4 to rise, causing the lower mold 1 to separate from the upper mold 4. The formed product is then manually removed, thus completing one production cycle of the synchronous belt pulley side plate. During this process, when the lower mold 1 separates from the upper mold 4, the device will be in a state of... Figure 1 In the middle form, when the upper mold 4 moves down and closes with the lower mold 1 under the action of the hydraulic rod 3, the inclined plate 9 also moves down with the upper mold 4. The position of the extension plate 5 is always fixed. When the inclined plate 9 moves down with the upper mold 4, it pulls the connecting rod 11, so that the end of the connecting rod 11 connected to the L-shaped plate 10 gradually forms a curved state. During the process, the L-shaped plate 10 rotates at the bottom of the extension plate 5 with the rotation angle of the connecting rod 11. When the connecting rod 11 pulls the top of the L-shaped plate 10 and it is curved, the bottom of the L-shaped plate 10 will rotate along the extension plate 5 as the center, turning the bottom end of the L-shaped plate 10 to the other side of the lower mold 1. At the same time, the long rod 16 slides inside the slide groove 12 and moves with the L-shaped plate 10. This makes the position of the scraper 7 also turn to the other side of the lower mold 1. At this time, the lower mold 1 and the upper mold 4 will complete the mold closing. After injection molding is completed, the upper mold 4 rises away from the lower mold 1. During this process, the inclined plate 9 moves upward to reset, driving the L-shaped plate 10 and the connecting rod 11 back to their initial state. This causes the bottom end of the L-shaped plate 10 to rotate to the other side of the lower mold 1. At this time, the lower mold 1 separates from the upper mold 4, and the finished product is exposed. When the L-shaped plate 10 resets to the other side, the long rod 16 slides inside the slide groove 12 and moves with the L-shaped plate 10. This causes the long rod 16 to move horizontally at the top of the lower mold 1, so that the scraper 7 fits against the surface of the lower mold 1 to remove burrs from the exposed injection molded product surface. At the same time, it removes the overflow material generated during injection molding on the surface of the lower mold 1. When the long rod 16 moves horizontally, the sliding rod 15 is restricted to sliding along the inner wall of the long groove 14. This causes the sliding rod 15 to move along the inner wall of the long groove 14 when the long rod 16 moves horizontally. As the inner wall of the long groove 14 is wavy, the slide bar 15 will move along the inner wall of the long groove 14 in a wavy manner, thereby driving the long bar 16 to move left and right repeatedly. This allows the long bar 16 to move left and right repeatedly on the inner wall of the slide groove 12. At the same time, the long bar 16 will adjust its position on the inner wall of the slide groove 12 according to the rotation angle of the L-shaped plate 10, ensuring that it moves with the L-shaped plate 10. This process will allow the long bar 16 to move left and right repeatedly while moving horizontally, thereby driving the scraper 7 to move horizontally and scrape on the surface of the lower mold 1, while pushing the waste material to the waste box 18 and scraping the waste material into the waste box 18 for collection. At the same time, the scraper 7 will move left and right to perform friction scraping, so that when scraping the burrs on the surface of the lower mold 1 and the surface of the finished product, the scraper 7 has a sawing-like cutting force, which can move horizontally and cut repeatedly. When the upper mold 4 moves down and closes with the lower mold 1, the irregular plate 23 will slide along the inner wall of the lifting groove 22. After the upper mold 4 moves down to a certain position, the irregular plate 23 will slide to the bottom of the inner wall of the lifting groove 22. At the same time, the bottom of the irregular plate 23 will press down on the right-angle plate 19, causing the right-angle plate 19 to move downward and push it into the bottom of the inner wall of the limiting groove 21. This also drives the mold module 8 to reset to the middle of the inner wall of the lower mold 1, so that the mold module 8 and the inner wall of the lower mold 1 form a complete lower mold groove. After injection molding, the upper mold 4 gradually rises, which will drive the irregular plate 23 to reset. The irregular plate 23 will first slide upward along the lifting groove 22, and after sliding to the bottom of the inner wall of the lifting groove 22, it will pull the right-angle plate 19 upward, causing the right-angle plate 19 to... 9 rises along the inner wall of the limiting groove 21, while the right-angle plate 19 drives the mold module 8 to move upward from the circular groove 20, so that the mold module 8 pushes the injection molded product embedded in the inner wall of the forming groove of the lower mold 1 upward, thereby completing the demolding process of the product on the inner wall of the lower mold 1. During the process, the irregular plate 23 will slide upward along the lifting groove 22 first, so that when the upper mold 4 rises, it will not drive the mold module 8 to move upward first. When the upper mold 4 is about to move to the top, it will drive the mold module 8 to eject the injection molded product, thus not affecting the L-shaped plate 10 to drive the scraper 7 to move on the surface of the lower mold 1. At the same time, when the upper mold 4 descends, the inner wall of the lifting groove 22 is no longer bound by the irregular plate 23 and will naturally fall back to the inside of the circular groove 20 due to the gravity of the mold module 8 and the right-angle plate 19.
