Description

Technical Field

[0001] The present application relates to the field of mold technology, and in particular to a secondary ejection mechanism and a mold. Background Art

[0002] In the plastic molding process, mold design and process optimization are critical to ensuring product quality and production efficiency. Plastic molds are typically used to inject molten plastic into the mold cavity, where it cools to form the product into the desired shape. However, in actual production, due to factors such as design, materials, and process, product release issues often become a significant factor limiting production efficiency and quality.

[0003] In plastic molding, the product's glue level, structural complexity, and mold design all directly impact clamping force. When the glue level of a plastic product is high, the required clamping force increases significantly. Consequently, the mold ejection mechanism may not be able to fully eject the product from the mold cavity during a single ejection. This phenomenon is particularly pronounced in products with complex structural designs. Parts of the structure may remain on the ejection mechanism, preventing the product from automatically detaching, increasing the complexity of subsequent manual or mechanical removal.

[0004] In this case, production workers or machines need to intervene to pick up the parts. However, due to the complex shape of the product, the gripping point may be unclear due to product design limitations during the gripping process, which brings difficulties to the operation. This not only reduces production efficiency, but may also cause accidental damage to the product during the gripping process, further affecting the product's appearance, function and overall quality. Utility Model Content

[0005] In order to improve the problem that the product cannot be completely pushed out of the mold cavity during the ejection process, the present application provides a secondary ejection mechanism and a mold.

[0006] The secondary ejection mechanism and mold provided in this application adopt the following technical solutions:

[0007] A secondary ejection mechanism comprises an ejector pin, a sleeve, a lever assembly, a pressure block and an ejector plate, wherein the ejector pin, the sleeve and the lever assembly are mounted in the ejector plate, the lever assembly is rotatably arranged and abuts against the sleeve, the ejector pin is passed through the sleeve, one end of the ejector pin and the sleeve passes through the ejector plate and is used to eject the product, and the pressure block is used to apply pressure to the lever assembly to rotate the lever assembly;

[0008] The ejector plate is driven to move, and the ejector pin, the sleeve and the lever assembly are driven to move together. After the ejector pin and the sleeve move, they jointly eject the product a certain distance, completing one ejection operation. The ejector plate is continued to be driven to move. When the lever assembly contacts the pressure block, the pressure block applies pressure to the lever assembly, causing one end of the lever assembly to move downward and the other end to move upward, thereby pushing the sleeve to move further. The sleeve ejects the product again, completing the secondary ejection operation.

[0009] By adopting the above technical solution, the design of the secondary ejection mechanism can effectively eject the product through the cooperation of the ejector pin, sleeve, lever assembly and pressure block, which can effectively improve the product's shedding rate. By providing secondary ejection power, it ensures the complete separation of the product in the complex mold and avoids damage caused by adhesion. In addition, the mechanism adopts the lever principle to reduce the direct impact on the product, which can effectively protect the appearance and functional integrity of the product and reduce the rework rate. The mechanism can adapt to plastic products of different shapes, sizes and complexities, making the mold design more flexible and improving the applicability of the production line.

[0010] In a specific possible implementation scheme, the lever assembly includes a pry plate and a rotating shaft. The pry plate is fixed to the top plate through the rotating shaft. A bayonet is provided on the pry plate. One end of the ejector pin is fixed to the top plate, and the other end first passes through the bayonet and then through the ejector sleeve. The ejector sleeve abuts against the pry plate.

[0011] By adopting the above technical solution, the lever assembly achieves greater ejection force through the rotation of the pry plate, which can more effectively push the product out of the mold and improve ejection efficiency. In addition, compared with the direct force application method, the rotation of the pry plate reduces direct contact and wear between mechanical components, extending the service life of the equipment and reducing maintenance costs.

[0012] In a specific possible implementation manner, the ejector pin interferes with the bayonet, and the bayonet slides along the ejector pin.

[0013] By adopting the above technical solution, the sliding contact of the bayonet on the ejector pin can maintain the alignment of the component throughout the entire operation process, ensuring that the pry plate can accurately perform the secondary ejection action, avoiding incomplete ejection or damage caused by misalignment. In addition, the sliding of the bayonet along the ejector pin provides a smooth operation process, ensuring stable ejection of the product.

[0014] In a specific embodiment, the sleeve is provided with a boss, the boss abuts against the pry plate and is arranged across the bayonet.

[0015] By adopting the above technical solution, the direct contact design between the boss and the pry plate ensures effective force transmission. The setting of the boss across the bayonet can effectively enhance the stability of the entire assembly. When the pry plate is working, the presence of the boss can prevent the pry plate from lateral deviation during movement, ensuring that it always remains on the predetermined working trajectory.

[0016] In a specific possible implementation scheme, a spring is further included. A reset groove is provided in the top plate, and the spring is provided in the reset groove. The spring is sleeved on the outer wall of the cylinder, and one end of the spring abuts against the groove wall of the reset groove, and the other end abuts against the boss.

[0017] By adopting the above technical solution, the quick recovery characteristics of the spring can complete the reset of the sleeve in a short time, reducing downtime and thus improving overall work efficiency. The presence of the spring can not only provide a quick reset function, but also buffer the impact force, reduce mechanical wear and protect the key components of the equipment.

[0018] In a specific possible implementation scheme, the contact surface between the pry plate and the boss is set to be a plane, and the upper and lower sides of the pry plate are provided with rotation notches.

[0019] By adopting the above technical solution, the contact surface between the pry plate and the boss is designed to be a plane, which can ensure that the contact between the two is more stable, reduce friction resistance, and improve the load-bearing capacity of the contact surface; the design of providing rotation notches on the upper and lower sides of the pry plate can reduce the obstruction of the pry plate during movement, allowing it to move more flexibly.

[0020] In a specific possible implementation scheme, the top plate is provided with a groove, the groove is arranged corresponding to the pressure block, the pry plate extends into the groove and forms a power structure, and the pressure block applies pressure to the power structure through the groove to rotate the pry plate.

[0021] By adopting the above technical solution and utilizing the corresponding arrangement of the groove and the pressure block, it is ensured that when the pressure block acts on the pry plate, force can be accurately applied to the power structure of the pry plate. The pry plate extends into the interior of the groove, forming a power structure with the pressure block. This structure enables the pry plate to rotate effectively when subjected to the pressure applied by the pressure block, thereby increasing the flexibility and responsiveness of the operation.

[0022] In a specific possible implementation scheme, the contact surface between the power structure and the pressing block is set as a curved surface.

[0023] By adopting the above technical solution, the curved contact surface enables the pressure block to better cooperate with the power structure. The curved surface can optimize the transmission and application of force, so that the force applied to the pry plate during rotation is more uniform. In addition, due to the curvature characteristics of the curved surface, the pry plate rotates more smoothly after being subjected to force, the friction during movement is reduced, and energy loss is reduced, thereby improving the working efficiency and stability of the entire system.

[0024] In a specific embodiment, it further includes a travel positioning column, which is arranged to pass through the top plate, and the top plate is slidably connected to the travel positioning column.

[0025] By adopting the above technical solution, the introduction of the stroke positioning column ensures the precise positioning of the top plate within a specific stroke, thereby enhancing the control accuracy of the entire system. In addition, the sliding connection design between the top plate and the stroke positioning column can effectively reduce vibration and instability during movement, thereby improving the stability of the mechanical system during operation.

[0026] A mold comprises a forming plate, a mounting plate and a bottom plate arranged in sequence from top to bottom, the mold includes the secondary ejection mechanism as described above, the ejector plate is arranged in the mounting plate and slides in the mounting plate, one end of the pressure block is fixed on the forming plate, and the other end is located in the mounting plate, the sleeve and the ejector pin pass through the mounting plate and are inserted into the forming plate to contact the product.

[0027] By adopting the above technical solution, the mold using the above secondary ejection mechanism has significant advantages in improving ejection efficiency, enhancing molding stability, optimizing pressure application methods, and improving operational convenience. The secondary ejection mechanism of the mold can effectively eject the product after it is formed through the cooperation of the ejector pin, sleeve, lever assembly and pressure block, ensuring that the finished product is smoothly ejected from the mold, reducing product damage caused by demolding difficulties, and ensuring the quality of the finished product.

[0028] To sum up, the beneficial technical effects of the present application are: effective ejection is achieved through the cooperation of the ejector pin, sleeve, lever assembly and pressure block, thereby improving the product's shedding rate. The mechanism ensures the complete detachment of the product from the complex mold by providing secondary ejection power, avoiding damage caused by adhesion; and the mechanism adopts the lever principle to reduce the direct impact on the product, which can effectively protect the product's appearance and functional integrity and reduce the rework rate. The mechanism can adapt to plastic products of different shapes, sizes and complexities, making the mold design more flexible and improving the applicability of the production line.

DETAILED DESCRIPTION

[0035] The following is combined with Figure 1-5 This application is described in further detail.

[0036] Reference Figure 1 and Figure 2 , the embodiment of the present application discloses a secondary ejection mechanism, including an ejector pin 1, a sleeve 2, a lever assembly 3, a pressure block 4 and an ejector plate 5. The ejector pin 1, the sleeve 2 and the lever assembly 3 are installed in the ejector plate 5. One end of the ejector pin 1 and the sleeve 2 passes through the ejector plate 5 and is used to eject the product 9. In this embodiment, the ejector pin 1 and the sleeve 2 are both vertically arranged. The ejector pin 1 passes through the sleeve 2. Both ends of the ejector pin 1 pass through the sleeve 2, and one end of the ejector pin 1 contacts the product 9. The lever assembly 3 is rotatably arranged in the ejector plate 5 and abuts against the sleeve 2. The pressure block 4 is used to apply pressure to the lever assembly 3 to rotate the lever assembly 3.

[0037] In this embodiment, a driving member is further included, which is connected to the top plate 5 and is used to drive the top plate 5 to move up and down along the vertical direction Y;

[0038] After the injection molding is completed, the driving member is started to drive the ejector plate 5 to move upward in the vertical direction Y. The ejector plate 5 drives the ejector pin 1, the sleeve 2 and the lever assembly 3 to move upward together. After the ejector pin 1 and the sleeve 2 move, they jointly eject the product 9 a certain distance, completing the first ejection of the product 9; the ejector plate 5 is continued to be driven upward. When the lever assembly 3 on the ejector plate 5 contacts the pressure block 4, the pressure block 4 applies downward pressure. The downward pressure of the pressure block 4 causes one end of the lever assembly 3 to move downward, causing the lever assembly 3 to rotate. According to the lever principle, the other end of the lever assembly 3 moves upward, thereby pushing the sleeve 2 to move further upward. The sleeve 2 acts on the product 9 again to eject the product 9, completing the second ejection of the product 9, and the product 9 is completely separated from the mold 8;

[0039] The design of the secondary ejection mechanism can effectively improve the shedding rate of the product 9. By providing secondary ejection power, it ensures the complete separation of the product 9 from the complex mold 8 and avoids damage caused by adhesion. In addition, the mechanism adopts the lever principle to reduce the direct impact on the product 9, which can effectively protect the appearance and functional integrity of the product 9 and reduce the rework rate. The mechanism can adapt to plastic products 9 of different shapes, sizes and complexities, making the mold 8 design more flexible and improving the applicability of the production line.

[0040] Reference Figure 2 and Figure 3 The lever assembly 3 includes a pry plate 31 and a rotating shaft 32. The pry plate 31 is fixed to the top plate 5 through the rotating shaft 32. In this embodiment, the rotating shaft 32 is arranged horizontally, passes through the pry plate 31 and is fixedly connected to the pry plate 31. The end of the rotating shaft 32 passes through the pry plate 31 and is rotatably arranged on the top plate 5.

[0041] The cam 35 is provided with a plurality of springs 52 and 53, and the springs 53 are provided with a plurality of springs 54 and 55 respectively. The cam 35 is provided with a plurality of springs 52 and 53 respectively. The cam 35 is provided with a plurality of springs 54 and 53 respectively. The cam 35 is provided with a plurality of springs 54 and 53 respectively.

[0042] In this embodiment, the contact surface between the power structure 35 and the pressure block 4 is configured as an arc surface. The arc-shaped contact surface enables the pressure block 4 to better cooperate with the power structure 35. The arc surface can optimize the transmission and application of force, so that the force applied to the pry plate 31 during rotation is more uniform. Moreover, due to the curvature characteristics of the arc surface, the pry plate 31 rotates more smoothly after being subjected to force, and the friction during the movement is reduced, thereby reducing energy loss, thereby improving the working efficiency and stability of the entire system.

[0043] The bottom end of the sleeve 2 is located in the upper top plate 51, and the other end passes through the upper top plate 51 and contacts the product 9. The bottom end of the sleeve 2 abuts against the side of the pry plate 31 away from the lower top plate 52. The sleeve 2 is provided with a boss 21. The sleeve 2 abuts against the pry plate 31 through the boss 21, and the boss 21 is arranged across the bayonet 33. The direct abutment design of the boss 21 and the pry plate 31 ensures effective force transmission. The arrangement of the boss 21 across the bayonet 33 can effectively enhance the stability of the entire assembly. When the pry plate 31 is working, the presence of the boss 21 can prevent the pry plate 31 from lateral deviation during movement, ensuring that it always remains on the predetermined working trajectory.

[0044] A bayonet 33 is provided on the pry plate 31. One end of the ejector pin 1 is fixed to the lower ejector plate 52, and the other end first passes through the bayonet 33 and then through the sleeve 2 and out of the sleeve 2 to contact the product 9. The outer wall of the ejector pin 1 contacts the inner wall of the bayonet 33, and the bayonet 33 slides along the ejector pin 1. The sliding contact of the bayonet 33 on the ejector pin 1 can maintain the alignment of the components throughout the operation, ensuring that the pry plate 31 can accurately perform the secondary ejection action, avoiding incomplete ejection or damage due to misalignment. In addition, the sliding of the bayonet 33 along the ejector pin 1 provides a smooth operation process, ensuring the stable ejection of the product 9.

[0045] The contact surface between the pry plate 31 and the boss 21 is flat, and rotation notches 34 are provided on the upper and lower sides of the pry plate 31. When force is applied to the pry plate 31, the flat contact surface ensures uniform force transmission, allowing the pry plate 31 to effectively contact the boss 21 and achieve prying. Due to the presence of the notch, the pry plate 31 can rotate when force is applied, further enhancing the prying effect. The presence of the rotation notch 34 can reduce obstruction to the movement of the pry plate 31, allowing it to move more flexibly.

[0046] The cam 35 of the cam 35 is pressed against the top of the cam 35 and the cam 36 is released, and the cam 36 is released, so that the cam 35 of the cam 35 can be pushed upward and the cam 36 is released, thereby the cam 36 is pushed upward and the cam 36 is released.

[0047] Reference Figure 2 and Figure 3 , the secondary ejection mechanism also includes a spring 6. In this embodiment, a reset groove 53 is provided in the upper top plate 51. The reset groove 53 is connected to the cavity 55. In this embodiment, the reset groove 53 is arranged along the outer circumference of the sleeve 2. The sleeve 2 and the ejector pin 1 first pass through the reset groove 53 and then pass through the top plate 5. The spring 6 is arranged in the reset groove 53 and is sleeved on the outer wall of the sleeve 2. One end of the spring 6 abuts against the groove wall of the reset groove 53, and the other end abuts against the boss 21.

[0048] During the secondary ejection process, the sleeve 2 continues to rise, and the sleeve 2 and its boss 21 move further upward. At this time, the spring 6 is gradually compressed, and its elastic potential energy increases accordingly. When the ejection work is completed, the top plate 5 is driven to move down and reset. At this time, the compressed state of the spring 6 is released, and the elastic potential energy of the spring 6 will be converted into kinetic energy. The spring 6 will quickly return to its original length and transfer the kinetic energy it generates to the sleeve 2, driving the sleeve 2 to quickly return to its initial position; through the rapid recovery characteristics of the spring 6, the sleeve 2 can be reset in a short time, reducing downtime, thereby improving overall work efficiency. The presence of the spring 6 not only provides a rapid reset function, but also buffers impact force, reduces mechanical wear, and protects key components of the equipment.

[0049] Reference Figure 2The secondary ejection mechanism also includes a stroke positioning column 7, which is vertically arranged and passes through the top plate 5. The top plate 5 is slidingly connected to the stroke positioning column 7. During the operation of the top plate 5, the stroke positioning column 7 provides a stable sliding track, allowing the top plate 5 to move up and down smoothly on the track. The introduction of the stroke positioning column 7 ensures the precise positioning of the moving parts within a specific stroke, thereby enhancing the control accuracy of the entire system. In addition, the sliding connection design between the top plate 5 and the stroke positioning column 7 can effectively reduce vibration and instability during movement, thereby improving the stability of the mechanical system during operation.

[0050] Reference Figure 4 and Figure 5 The present application further provides a mold 8, which includes a movable mold and a fixed mold. The fixed mold includes a forming plate 81, a mounting plate 82, and a bottom plate 83 arranged in sequence from top to bottom. In this embodiment, a core 84 for producing a product 9 is provided on the forming plate 81. The forming plate 81, the mounting plate 82, and the bottom plate 83 are fixed together including but not limited to being connected by bolts.

[0051] The mold 8 includes the secondary ejection mechanism as described above. In this embodiment, the secondary ejection mechanism is installed on the fixed mold. The number of secondary ejection mechanisms on the mold 8 can be designed according to the number and structure of the products 9 actually produced by the mold 8. In the secondary ejection mechanism: the top plate 5 is arranged in the mounting plate 82, and the top plate 5 slides up and down in the mounting plate 82 along the vertical direction Y. One end of the pressure block 4 is fixed on the forming plate 81, and the other end is located in the mounting plate 82 and corresponds to the groove 54 of the top plate 5. The sleeve 2 and the ejector pin 1 pass through the mounting plate 82 and are inserted into the forming plate 81 and the core 84 to contact the product 9 in the core 84. In this embodiment, one end of the travel positioning column 7 abuts against the bottom plate 83 and is fixed to the bottom plate 83 by bolts, and the other end passes through the top plate 5 and abuts against the forming plate 81 and is fixed;

[0052] After the injection molding of the mold 8 is completed, the movable mold is driven to move away from the fixed mold. At this time, the product 9 on the core 84 of the fixed mold is exposed; the driving member is started to drive the ejector plate 5 to move upward in the vertical direction Y. During this process, the ejector plate 5 moves upward along the travel positioning column 7, and the ejector plate 5 drives the ejector pin 1, the sleeve 2 and the lever assembly 3 to move upward together. After the ejector pin 1 and the sleeve 2 move, they jointly eject the product 9 a certain distance, completing the ejection of the product 9.

[0053] Continue to drive the top plate 5 to move upward. When the lever assembly 3 on the top plate 5 contacts the pressure block 4, the pry plate 31 contacts the pressure block 4. The power structure 35 of the pry plate 31 is subjected to the downward pressure exerted by the pressure block 4. The pressure block 4 presses the power structure 35 of the pry plate 31 downward. The downward movement of the power structure 35 causes the pry plate 31 to rotate. One side of the bayonet 33 of the pry plate 31 rotates upward along the ejector pin 1. The rotation of the pry plate 31 causes the sleeve 2 abutting against its plane to rise. By utilizing the principle of leverage, one end of the bayonet 33 of the pry plate 31 rises, pushing the sleeve 2 boss 2 up, thereby continuing to push the sleeve 2 upward, further pushing the product 9, completing the secondary ejection, and the product 9 completely leaving the mold 8.

[0054] During the secondary ejection process, the sleeve 2 continues to rise, and the sleeve 2 and its boss 21 move further upward. At this time, the spring 6 is gradually compressed, and its elastic potential energy increases accordingly. When the ejection work is completed, the ejector plate 5 is driven to move down and reset. At this time, the compressed state of the spring 6 is released, and the elastic potential energy of the spring 6 is converted into kinetic energy. The spring 6 will quickly return to its original length and transfer the kinetic energy generated by it to the sleeve 2, driving the sleeve 2 to quickly return to its initial position, and the next injection molding work can be carried out;

[0055] The mold 8 of the present application uses the above-mentioned secondary ejection mechanism, which has significant advantages in improving ejection efficiency, enhancing molding stability, optimizing pressure application methods, and improving operational convenience. The secondary ejection mechanism of the mold 8 can effectively eject the product 9 after it is formed through the cooperation of the ejector pin 1, the sleeve 2, the lever assembly 3 and the pressure block 4, ensuring that the finished product is smoothly ejected from the mold 8, reducing damage to the product 9 caused by demolding difficulties, and ensuring the quality of the finished product; the design of the secondary ejection mechanism enables the mold 8 to adapt to products 9 of various shapes and sizes. By adjusting the length and position of the ejector pin 1 and the sleeve 2, different types of molded products 9 can be effectively processed, thereby enhancing the versatility of the mold 8.

[0056] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
