Description

Technical Field

[0001] The present invention relates to the technical field of injection molds, and specifically to an injection mold capable of recycling plastic waste. Background Art

[0002] An injection mold is a key tool for producing plastic products through the injection molding process. In this process, plastic raw materials are heated to a molten state and then injected into the mold. After cooling and solidifying, plastic products with a predetermined shape are formed. However, with the wide application of the injection molding process, the recycling and reuse of plastic waste have become an important means to reduce production costs and environmental pollution. Currently, there are still certain defects in existing injection molds in practical applications. Especially after the mold production is completed, excess waste is likely to be generated on the mold surface, which not only affects production efficiency but also may lead to waste of raw materials.

[0003] In order to overcome the above defects, in the prior art one (a Chinese patent with the publication number CN119704552A and the publication date of March 28, 2025), a battery slot injection mold and its edge waste treatment and recycling device include a fixed mold and a movable mold. An assembly seat is provided at the lower end of the fixed mold, and a demolding block protrudes from one side of the movable mold. A sunk groove is opened on the fixed mold, and an injection hole is opened at one end of the sunk groove away from the fixed mold. Outer clamping strips are distributed around the side wall of the sunk groove to reduce the friction force for the injection molded part to demold from the outside. A top plate is installed inside the movable mold, and a thimble rod is provided on the top plate. A hinge seat is installed on the movable mold, and a group of pressing arms are rotatably installed on the hinge seat. Inner clamping strips are distributed around the side wall of the demolding block to reduce the friction force for the injection molded part to demold from the inside. This mold can reduce the contact area between the inner and outer sides of the injection molded part and the mold during demolding, achieving the effects of reducing stress concentration and friction, and reducing the possibility of the molded part getting stuck in the mold. This edge waste treatment and recycling device can timely grind and recycle the burrs on the edge of the injection molded part. In the prior art two (a Chinese patent with the publication number CN211566756U and the publication date of September 25, 2020), a spare tire compartment injection mold with a floating positioning mechanism belongs to an injection mold, including an injection mold cavity and an injection mold core. The injection mold core seat is fixedly connected inside the injection mold core. The oil cylinder of the floating positioning mechanism is fixed above the inside of the floating positioning mechanism seat. The bottoms of two profiling positioning pins are fixedly connected above the positioning pin connecting plate through screws. The two profiling positioning pins and the positioning pin connecting plate are located outside the floating positioning mechanism seat, and the two profiling positioning pins are slidably connected to the holes in the injection mold core. The front ends of the two profiling positioning pins are located outside the injection mold core. The front end of the cylinder rod of the oil cylinder is fixedly connected to the middle part below the positioning pin connecting plate.

[0004] Although the prior art can reduce waste of resources, during the working process, the burrs on the edge of the injection molded part are polished and recycled in a timely manner through the structure, and the floating positioning mechanism reduces the gap between the molds. The overall structure is complex, increasing the manufacturing difficulty and cost of the mold. Moreover, the overall space occupied is relatively large, affecting the adaptability of the mold. The excess plastic raw material inside the mold injection nozzle will be taken away by the molded part, resulting in unnecessary injection groove accumulation remaining on the molded part. Therefore, secondary treatment is required, which not only increases the production process but also increases the production cost and time.

[0005] In view of the above problems, there is an urgent need to innovate and design on the basis of the original injection mold for recycling plastic waste. Therefore, we have proposed an injection mold for recycling plastic waste that can well solve the above problems. Summary of the Invention

All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0024] Embodiment 1: In this embodiment, the cutting knife 8 on the lifting plate 7 separates the accumulated material in the injection groove inside the injection nozzle 4 from the formed part in the fixed mold 2, reducing the cost problem of secondary processing, such as Figures 1-8The described technical solution includes a movable mold 1 and a fixed mold 2. The movable mold 1 is moved by a driving cylinder 3. An injection groove 4 is provided inside the fixed mold 2, and a storage groove 5 is provided inside the fixed mold 2. A lifting plate 7 is connected inside the storage groove 5 through a driving component. A cutter 8 for cutting the accumulated material in the injection groove is provided on the lifting plate 7. The inside of the driving cylinder 3 drives a moving rod 9 through gas. An auxiliary component is provided inside the movable mold 1, and a conveying bladder 12 is provided on the auxiliary component. The output end of the conveying bladder 12 is connected to a blowing component. A vibration component is provided inside the storage groove 5. The auxiliary component includes a cavity 10 provided inside the movable mold 1. After the moving rod 9 moves, it contacts the ejector 11. The ejector 11 is located inside the cavity 10, and the moving rod 9 is located inside the conveying bladder 12. When the moving rod 9 moves, it squeezes the conveying bladder 12. The driving component includes a telescopic cylinder 6 installed inside the storage groove 5. The output end of the telescopic cylinder 6 is connected to the bottom of the lifting plate 7. The blowing component includes a conveying pipeline 13 connected to the output end of the conveying bladder 12. The output end of the conveying pipeline 13 is connected to a first pipeline 15 and a second pipeline 16 through a connector. The ends of the first pipeline 15 and the second pipeline 16 are located on the inner wall of the injection groove 4, and the gas inside the first pipeline 15 and the second pipeline 16 is transported unidirectionally. A conveying cylinder 14 is provided inside the storage groove 5. The first pipeline 15 is connected through the inside of the conveying cylinder 14. An annular conveying cavity 17 is provided inside the conveying cylinder 14. The inside of the conveying cavity 17 is communicated with the inner cavity of the conveying cylinder 14 through an interface 18. The first pipeline 15 is connected to the inside of the conveying cavity 17 through the inner cavity of the conveying cylinder 14. The interface 18 inside the inner cavity of the conveying cylinder 14 is adapted to a blocking rod 19. The blocking rod 19 is connected to the bottom of the lifting plate 7. The vibration component includes a toothed block 20 installed on the side end of the lifting plate 7. A support 23 is provided inside the storage groove 5. A gear 21 is connected to the support 23 through a rotating shaft 22. The gear 21 meshes with the toothed block 20. A striking member 24 for knocking on the storage groove 5 and the injection groove 4 is provided on the rotating shaft 22. A torsion spring 25 for rebounding is provided on the outside of the rotating shaft 22. The driving cylinder 3 drives the movable mold 1 of the injection mold to move to the side of the fixed mold 2. At this time, the plastic raw material is conveyed to the injection nozzle 4 and flows into the inside of the movable mold 1 and the fixed mold 2 through the injection nozzle 4. The cooling structure of the injection molding machine is started, so that the molded parts inside the movable mold 1 and the fixed mold 2 are cooled and solidified. At this time, the driving component inside the storage groove 5 is opened. The driving component in this embodiment is a telescopic cylinder 6. The telescopic cylinder 6 drives the upper lifting plate 7 to move, which is convenient for the cutter 8 on the lifting plate 7 to separate the accumulated material in the injection nozzle 4 from the molded parts inside the fixed mold 2. The whole can accurately cut off the connection between the accumulated material and the molded parts, avoid the accumulated material sticking to the molded parts during the subsequent demolding process, ensure the appearance quality of the molded parts, and at the same time make the accumulated material in the injection groove easy to collect, reduce the waste residue, and improve the efficiency of waste recycling. The overall structure is simple, reducing the problem of inconvenient maintenance caused by setting complex structures. At this time, the driving cylinder 3 drives the movable mold 1 to move the molded parts, and gas is injected into the driving cylinder 3, so that the gas squeezes the moving rod 9 to move.The moving rod 9 drives the ejector 11 to move inside the cavity 10. The ejector 11 facilitates the movement of the molded part out of the female mold 1, improving the automation degree and production efficiency of the device's demolding. When the moving rod 9 moves inside the driving cylinder 3, it squeezes the conveying bladder 12, causing the gas inside the conveying bladder 12 to be transmitted through the conveying pipe 13 to the inside of the conveying cylinder 14 and the second pipe 16. The gas inside the conveying cylinder 14 is output through the first pipe 15. The gas ejected from the first pipe 15 and the second pipe 16 loosens the accumulated material in the injection groove inside the injection nozzle 4. Overall, using the energy generated during the demolding process, the gas is transmitted to the injection nozzle to loosen the accumulated material, facilitating the collection of the accumulated material later. The overall energy consumption is low, improving the overall resource utilization rate. The cutting knife 8 at the upper end of the lifting plate 7 is driven by the telescopic cylinder 6 to move downward. At this time, the blocking rod 19 on the side of the lifting plate 7 moves into the conveying cylinder 14. When the blocking rod 19 moves to the interface 18 of the conveying cylinder 14, the passage between the inside of the conveying cavity 17 and the first pipe 15 is blocked, causing the gas passing through the second pipe 16 to be blown out under pressure, and the accumulated material in the injection groove inside the injection nozzle 4 is blown out, facilitating the collection of the accumulated material in the injection groove later and reducing the waste of resources. The overall structure is simple, reducing the problem of reduced mold adaptability caused by setting a larger structure. When the lifting plate 7 moves up and down, the tooth block 20 on its side contacts the gear 21 on the support 23. The gear 21 is driven to rotate by the tooth block 20, and the gear 21 drives the rotating shaft 22 to rotate, facilitating the striker 24 on the rotating shaft 22 to strike the placement groove 5, causing the injection nozzle 4 to vibrate, facilitating the accumulated material in the injection groove to shake and fall. Through the cooperation of the vibration component and the blowing component, the accumulated material in the injection groove can be thoroughly cleaned, improving the effect of waste recycling and treatment. Since a torsion spring 25 is arranged outside the rotating shaft 22, when the tooth block 20 moves away from the surface of the gear 21, the rotating shaft 22 drives the gear 21 to return to its initial position through the rebound of the torsion spring 25. Overall, it reduces the problem of increased overall production processes caused by the accumulated material in the injection groove on the molded part, reducing the overall production cost and time.

[0025] Embodiment 2: In this embodiment, the flexible movement of the lifting plate 7 is realized through an electromagnetic drive structure. The overall drive response speed is fast, and the separation operation of the cutting knife 8 on the accumulated material can be quickly realized. Specifically, as Figures 1-4 and Figure 9As shown, it is disclosed that: The driving component includes a first electromagnetic block 26 installed inside the storage slot 5. The first electromagnetic block 26 is adapted to the second electromagnetic block 27. The second electromagnetic block 27 is installed at the bottom of the lifting plate 7. The driving component of this embodiment is a cooperative structure of the first electromagnetic block 26 and the second electromagnetic block 27. By energizing the first electromagnetic block 26 and the second electromagnetic block 27 to generate magnetic force, the lifting plate 7 moves up and down. By changing the magnetism of the first electromagnetic block 26, when the magnetisms of the first electromagnetic block 26 and the second electromagnetic block 27 are opposite, the two generate suction force, facilitating the downward movement of the lifting plate 7 through the cooperation of the second electromagnetic block 27. When the magnetisms of the first electromagnetic block 26 and the second electromagnetic block 27 are the same, the two generate repulsive force, facilitating the second electromagnetic block 27 to drive the lifting plate 7 to move upward, facilitating the lifting plate 7 to drive the cutter 8 at the upper end to separate the accumulated material in the injection slot inside the injection nozzle 4 from the molded part in the fixed mold 2. Through the electromagnetic drive structure, the flexible movement of the lifting plate 7 is realized. The overall driving response speed is fast, and the separation operation of the accumulated material by the cutter 8 can be quickly realized, effectively improving the efficiency of waste recycling and treatment. And the electromagnetic force can be precisely adjusted by controlling the current magnitude to adapt to the separation requirements of accumulated materials with different hardnesses, enhancing the applicability of the mold.

[0026] Embodiment 3: In this embodiment, the lifting plate 7 moves upward through the rebound of the spring 29. The entire structure operates stably and reliably, facilitating later maintenance. Specifically, as shown in Figures 1-4 、 Figure 10 and Figure 11 As shown, it is disclosed that: The driving component includes a positioning rod 28 and a spring 29 installed inside the storage slot 5. The positioning rod 28 is connected through the inside of the lifting plate 7. A spring 29 is arranged outside the positioning rod 28. A storage box 30 is arranged inside the storage slot 5. A driving member 31 is arranged inside the storage box 30. The output end of the driving member 31 is connected with a positive and negative screw rod 32. A moving plate 34 is connected through the outside of the positive and negative screw rod 32. A guide rod 33 is connected through the inside of the moving plate 34. The upper end of the moving plate 34 is connected with an inclined block 35. The inclined block 35 is arranged in an inverted trapezoid shape. The inclined block 35 is located on the surface of the lifting plate 7. The driving component of this embodiment is a structure of the positioning rod 28 and the spring 29. Through the expansion and contraction of the spring 29, the lifting plate 7 performs a lifting operation on the positioning rod 28. Open the driving member 31 inside the storage box 30. Drive the positive and negative screw rod 32 to rotate through the driving member 31, so that the moving plate 34 on the positive and negative screw rod 32 performs a lateral movement through the cooperation of the guide rod 33, facilitating the inclined block 35 on the moving plate 34 to squeeze the lifting plate 7. Since a spring 29 is arranged outside the positioning rod 28, when the inclined block 35 moves away from the surface of the lifting plate 7, the lifting plate 7 moves upward through the rebound of the spring 29, facilitating the lifting plate 7 to drive the cutter 8 at the upper end to separate the accumulated material in the injection slot inside the injection nozzle 4 from the molded part in the fixed mold 2. The entire structure operates stably and reliably, facilitating later maintenance.
