Description

Technical Field

[0001] This utility model relates to the field of mold technology, and in particular to a two-color mold slider anti-retraction structure. Background Technology

[0002] Two-color mold sliders are a key component in two-color injection molds, used to mold products with complex shapes. The design and application of two-color mold sliders play a crucial role in the two-color injection molding process. Sliders are typically used to handle parts of the product that require core pulling or movement, ensuring smooth demolding and maintaining the desired shape and quality.

[0003] The existing Chinese patent with publication number CN116141592A discloses a simplified two-color mold sliding block mechanism that does not retract during the first shot and retracts during the second shot. This relates to the field of injection molding equipment technology. The mechanism includes a male mold plate and a female mold plate. The female mold plate contains a sliding block lever and a sliding block clamping block. The male mold plate contains a sliding block, a sliding block seat, a sliding block movable, a sliding block floating, and an elastic component. The sliding block movable is installed inside the sliding block seat and slidably connected to it via a groove. During the first shot, the female mold does not have a sliding block lever, so the sliding block does not open when the mold opens. During the second shot, when the mold closes, the sliding block lever pushes the sliding block movable downwards, and simultaneously, the sliding block movable moves backwards along the groove. While moving backwards, the sliding block movable pushes the sliding block floating downwards. The sliding block lever pushes the sliding block movable to a certain distance, at which point the sliding block movable disengages from the sliding block lever. The elastic component, through the stored energy, pushes the sliding floating block to reset, and the elastic component pushes the sliding block movable to reset. This design simplifies the overall structure.

[0004] While this patented technology has an anti-retraction effect, its structure is relatively auxiliary and requires the combined operation of multiple components to achieve the desired effect. When a certain operating component malfunctions or is damaged, it directly affects the anti-retraction effect of the structure. Although the complex structure can achieve more effects, it also increases the problems. When performing a single process, a simplified structure can be used. Further processing and improvement of the air structure are required, which increases the number of processes and reduces work efficiency. Therefore, the inventor has proposed a dual-color mold slider anti-retraction structure to solve the above-mentioned technical problems. Utility Model Content

[0005] To overcome the shortcomings mentioned above, this utility model aims to provide a technical solution that can solve the aforementioned problems.

[0006] A dual-color mold slider anti-retraction structure includes a connecting base and an anti-retraction frame. The connecting base and the anti-retraction frame are independently set and are detachable. One end of the connecting base is a connecting platform, and the connecting base and the connecting platform are integrally formed. One end of the anti-retraction frame is connected to an anti-retraction rod, and a slider is connected to the surface of the anti-retraction rod. The slider can slide along the surface of the anti-retraction rod. The connecting base is U-shaped, and a movable pushing block is connected inside the connecting base. The slider is located on the surface of the pushing block and fits against the surface of the pushing block. One end of the anti-retraction rod passes through the slider, and the other end of the anti-retraction rod is connected to an adjusting block. The end of the adjusting block near the slider is provided with a magnetic block for preventing the slider from retracting.

[0007] This structure operates using a horizontal opening and closing mold method. When the push block is pushed by the driving force of the external push rod, the driving force causes the push block to slide along the surface of the anti-retraction rod, and at the same time, it causes the slider to slide along the surface of the anti-retraction rod. When it moves to the position of the designated magnetic block, one end of the slider is in contact with the magnetic block, so that the magnetic block can attract the slider. When the mold is opened, the push block is reset. With the magnetic block attracting the slider, the reaction force of the push block is prevented from causing the slider to deviate to the designated position, thereby achieving the anti-retraction effect and completing the anti-retraction process, which facilitates the subsequent processes.

[0008] The simplified structure achieves the limiting effect and also enables mold opening and closing operations. While assisting in operation, it avoids the impact of anti-retraction on subsequent processes, improves work efficiency and progress, further reduces labor costs, lowers expenses, and saves costs.

[0009] Furthermore, both ends of the anti-retraction frame are equipped with push rods to assist the slider to retract. A buffer rubber block is installed at the end of the push rod near the slider. The buffer rubber block is arc-shaped and its surface is 1-2 mm higher than the surface of the magnetic block.

[0010] The design of the buffer rubber block can buffer the movement of the slider, reduce the hard collision between the slider and the anti-reverse frame, thereby reducing the impact force and protecting the equipment from damage. The arc-shaped design of the buffer rubber block can provide a smooth contact surface, making the slider more stable when it moves backward and reducing instability caused by collision.

[0011] By setting the buffer rubber block 1-2mm higher than the surface of the magnetic block, it is ensured that the slider contacts the buffer rubber block first when it approaches the limit position, preventing equipment or personal injury caused by hard collision. Through the buffering effect of the buffer rubber block, the position control accuracy of the slider during the backward movement can be improved, avoiding excessive displacement. Then, after the force of the slider stabilizes, the magnetism of the magnetic block attracts the slider. When the mold is opened, the anti-reverse frame or push block drives the slider to move, preventing it from being pulled away and achieving the anti-reverse effect.

[0012] Furthermore, the surface of the anti-reverse frame is provided with an adjustment groove for assisting the adjustment block in position adjustment. The adjustment block can slide along the inside of the adjustment groove. The surface of the adjustment groove is provided with a connecting groove for assisting the external screw in installing the adjustment block. The connecting groove passes through the adjustment groove and extends to the surface of the anti-reverse frame.

[0013] The adjusting block can slide along the adjusting groove to achieve accurate position adjustment, ensuring that the position of the equipment or component is accurate. The structure of free sliding in the adjusting groove improves the flexibility of adjustment and makes it easy to adjust the position according to different needs. At the same time, the guiding effect of the adjusting groove makes the adjusting block more stable during sliding, reducing position deviation caused by poor sliding.

[0014] The design of the connecting groove allows the adjusting block to be installed with the anti-reverse bracket via external screws, simplifying the installation and disassembly process. The design of the groove extends through the adjusting groove to the surface of the anti-reverse bracket, ensuring that the screws are more securely fixed and preventing the adjusting block from loosening or falling off during use. This allows the adjusting block to distribute pressure more evenly when under stress, reducing local stress concentration. The simple structural design reduces the complexity of the manufacturing process, lowers manufacturing costs, and improves operational safety.

[0015] Furthermore, both ends of the connecting base are provided with slots for assisting in positioning the connecting base. The inner surface of the slots is provided with blocks, which have a raised structure. The cooperation between the slots and the blocks ensures the positional accuracy of the connecting base and prevents positional deviations caused by improper installation. The raised blocks provide a more secure connection, preventing the connecting base from shifting or loosening due to external forces during use. In addition, the raised blocks stabilize the connection, reduce wear caused by friction on the inner surface of the slots due to vibration during operation, extend service life, distribute pressure evenly, reduce local stress concentration, and prevent sudden detachment during use, thus improving operational safety.

[0016] Furthermore, both ends of the connecting base are provided with a top block and a guide post for assisting in positioning the pushing block. One end of the top block abuts against the surface of the connecting base, and the surface of one end of the top block is in contact with the surface of the pushing block. One end of the guide post is higher than the surface of the top block and extends into the interior of the top block. The top block and the guide post work together to accurately position the pushing block, ensuring that it will not deviate during operation and improving the positioning accuracy of the overall device. The fact that the guide post is higher than the surface of the top block and extends into the interior of the top block can provide stronger support, preventing the pushing block from shaking or shifting due to external forces during operation and enhancing the stability of the device.

[0017] Furthermore, one end of the connecting base is provided with a mounting groove for assisting in the positioning of the connecting base. The mounting groove has a concave structure. The concave mounting groove can precisely align with the protruding parts of external mating parts, such as connectors or other components, thereby improving the positioning accuracy of the connecting base. The concave structure provides a more secure connection, preventing the connection from loosening or falling off due to vibration or external force, and enhancing the stability of the connection. In addition, the concave mounting groove makes it easier to align and insert connectors, facilitating installation and disassembly operations.

[0018] Furthermore, the surface of the connecting platform is provided with a chip removal groove for assisting in the discharge of chips; the chip removal groove can effectively guide the grease or lubricating oil generated during the mold opening and closing process to be discharged along a predetermined path, preventing grease from accumulating in the processing area and preventing grease from solidifying. In addition, the design of the chip removal groove makes the cleaning work more convenient, reducing the amount of work required to manually pick out and scrape off the grease during the cleaning process. Moreover, the effective chip removal design can reduce equipment failures caused by grease mixed with chips clogging, and improve the reliability and stability of the equipment.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows: It operates by using a horizontal opening and closing mold method. When the push block is pushed by the driving force of the external push rod, the driving force causes the push block to slide along the surface of the anti-retraction rod, and at the same time, it drives the slider to slide along the surface of the anti-retraction rod. When it moves to the position of the designated magnetic block, one end of the slider is attached to the magnetic block, so that the magnetic block can attract the slider. When the mold is opened, the push block is reset. When the magnetic block attracts the slider, the reaction force of the push block is prevented from causing the slider to deviate to the designated position, thereby achieving the anti-retraction effect and completing the anti-retraction process, which facilitates the subsequent processes.

[0020] The simplified structure achieves the limiting effect and also enables mold opening and closing operations. While assisting in operation, it avoids the impact of anti-retraction on subsequent processes, improves work efficiency and progress, further reduces labor costs, lowers expenses, and saves costs.

Detailed Implementation

[0027] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0028] For this embodiment, please refer to Figures 1-5 The specific implementation of the dual-color mold slider anti-retraction structure includes a connecting base 1 and an anti-retraction frame 2. The connecting base 1 and the anti-retraction frame 2 are independently set and are detachable. One end of the connecting base 1 is a connecting platform 3, and the connecting base 1 and the connecting platform 3 are integrally formed. One end of the anti-retraction frame 2 is connected to an anti-retraction rod 4, and a slider 5 is connected to the surface of the anti-retraction rod 4. The slider 5 can slide along the surface of the anti-retraction rod 4. The connecting base 1 is U-shaped, and a movable push block 6 is connected inside the connecting base 1. The slider 5 is located on the surface of the push block 6 and is in contact with the surface of the push block 6. One end of the anti-retraction rod 4 passes through the slider 5, and the other end of the anti-retraction rod 4 is connected to an adjusting block 7. The adjusting block 7 is provided with a magnetic block 8 for preventing the slider 5 from retracting at the end near the slider 5.

[0029] This structure operates using a horizontal opening and closing mold method. When the push block 6 is pushed by the driving force of the external push rod, the driving force causes the push block 6 to slide along the surface of the anti-retraction rod 4, and at the same time, it drives the slider 5 to slide along the surface of the anti-retraction rod 4. When it moves to the designated position of the magnetic block 8, one end of the slider 5 is attached to the magnetic block 8, so that the magnetic block 8 can attract the slider 5. When the mold is opened, the push block 6 is reset. When the magnetic block 8 attracts the slider 5, the reaction force of the push block 6 is prevented from causing the slider 5 to shift to the designated position, thereby achieving the anti-retraction effect and completing the anti-retraction process, which facilitates the subsequent processes.

[0030] The simplified structure achieves the limiting effect and also enables mold opening and closing operations. While assisting in operation, it avoids the impact of anti-retraction on subsequent processes, improves work efficiency and progress, further reduces labor costs, lowers expenses, and saves costs.

[0031] Both ends of the anti-retraction frame 2 are equipped with push rods 9 for the sliding block 5 to retract. A buffer rubber block 10 is installed at the end of the push rod 9 near the sliding block 5. The buffer rubber block 10 is arc-shaped and the surface of the buffer rubber block 10 is 1-2mm higher than the surface of the magnetic block 8.

[0032] The design of the buffer rubber block 10 can buffer the slider 5 when it is in operation, reduce the hard collision between the slider 5 and the anti-reverse frame 2, thereby reducing the impact force and protecting the equipment from damage. The arc-shaped design of the buffer rubber block 10 can provide a smooth contact surface, making the slider 5 more stable when it moves backward and reducing instability caused by collision.

[0033] By setting the buffer rubber block 10 1-2mm higher than the surface of the magnetic block 8, it can be ensured that when the slider 5 approaches the limit position, it first contacts the buffer rubber block 10, preventing equipment or personal injury caused by hard collision. Through the buffering effect of the buffer rubber block 10, the position control accuracy of the slider 5 during the backward process can be improved, avoiding excessive displacement. Then, after the force of the slider 5 stabilizes, the magnetism of the magnetic block 8 attracts the slider 5. When the mold is opened, the anti-reverse frame 2 or the push block 6 drives the slider 5 to move, preventing the slider from being pulled along and achieving the anti-reverse effect.

[0034] The surface of the anti-retraction frame 2 is provided with an adjustment groove 11 for assisting the adjustment block 7 in position adjustment. The adjustment block 7 can slide along the inside of the adjustment groove 11. The surface of the adjustment groove 11 is provided with a connecting groove 12 for assisting the external screw to be installed with the adjustment block 7. The connecting groove 12 passes through the adjustment groove 11 and extends to the surface of the anti-retraction frame 2.

[0035] The adjusting block 7 can slide along the adjusting groove 11 to achieve accurate position adjustment and ensure that the position of the equipment or component is accurate. The structure of free sliding in the adjusting groove 11 improves the flexibility of adjustment and makes it easy to adjust the position according to different needs. At the same time, through the guiding effect of the adjusting groove 11, the adjusting block 7 is more stable during the sliding process, reducing the position deviation caused by poor sliding.

[0036] The design of the connecting groove 12 allows the adjusting block 7 to be installed with the anti-reverse bracket 2 via external screws, simplifying the installation and disassembly process. The use of a through-groove 11 extending to the surface of the anti-reverse bracket 2 ensures that the screws are more securely fixed, preventing the adjusting block 7 from loosening or falling off during use. This allows the adjusting block 7 to distribute pressure more evenly when under force, reducing local stress concentration. The simple structural design reduces the complexity of the manufacturing process, lowers manufacturing costs, and improves operational safety.

[0037] Both ends of the connecting base 1 are provided with slots 13 for assisting in positioning the connecting base 1. The inner surface of the slots 13 is provided with blocks 14, which have a raised structure. The cooperation between the slots 13 and the blocks 14 can ensure the positional accuracy of the connecting base 1 and prevent positional deviation caused by improper installation. The raised blocks 14 can provide a more secure connection and prevent the connecting base 1 from shifting or loosening due to external forces during use. In addition, the raised blocks 14 can stabilize the connection, reduce wear caused by friction on the inner surface of the slots 13 due to vibration during operation, and extend the service life. They can also distribute pressure evenly, reduce local stress concentration, and prevent sudden disengagement during use, thereby improving operational safety.

[0038] Both ends of the connecting base 1 are provided with a top block 15 and a guide post 16 to assist in positioning the push block 6. One end of the top block 15 abuts against the surface of the connecting base 1, and the surface of the top block 15 is in contact with the surface of the push block 6. One end of the guide post 16 is higher than the surface of the top block 15 and extends into the interior of the top block 15. The top block 15 and the guide post 16 work together to accurately position the push block 6, ensuring that it will not deviate during operation and improving the positioning accuracy of the overall device. The fact that the guide post 16 is higher than the surface of the top block 15 and extends into the interior of the top block 15 can provide stronger support and prevent the push block 6 from shaking or shifting due to external forces during operation, thereby enhancing the stability of the device.

[0039] One end of the connecting base 1 is provided with a mounting groove 17 for assisting in the positioning of the connecting base 1. The mounting groove 17 has a concave structure. The concave mounting groove 17 can accurately align with the protruding parts of external mating parts, such as connectors or other components, thereby improving the positioning accuracy of the connecting base 1. The concave structure can provide a more secure connection, preventing the connection from loosening or falling off due to vibration or external force, and enhancing the stability of the connection. In addition, the concave mounting groove 17 makes it easier to align and insert connectors, facilitating installation and disassembly operations.

[0040] The surface of the connecting platform 3 is provided with a chip discharge groove 18 for assisting in the discharge of chips. The chip discharge groove 18 can effectively guide the grease or lubricating oil generated during the mold opening and closing process to be discharged along a predetermined path, preventing the grease from accumulating in the processing area and preventing the grease from solidifying. In addition, the design of the chip discharge groove 18 makes the cleaning work more convenient, reducing the amount of work required to manually pick out and scrape off the grease during the cleaning process. Furthermore, the effective chip discharge design can reduce equipment failures caused by grease mixed with chips clogging, and improve the reliability and stability of the equipment.

[0041] The key design features of this invention are: it operates using a horizontal mold opening and closing mechanism. When the push block 6 is pushed by the driving force of the external push rod, the driving force causes the push block 6 to slide along the surface of the anti-retraction rod 4, while simultaneously causing the slider 5 to slide along the surface of the anti-retraction rod 4. When it moves to the designated position of the magnetic block 8, one end of the slider 5 is in contact with the magnetic block 8, thus facilitating the magnetic block 8 to attract the slider 5. When the mold is opened, the push block 6 is reset. With the magnetic block 8 attracting the slider 5, the reaction force of the push block 6 is prevented from causing the slider 5 to shift to the designated position, thereby achieving the anti-retraction effect and completing the anti-retraction process, which facilitates the subsequent processes.

[0042] The simplified structure achieves the limiting effect and also enables mold opening and closing operations. While assisting in operation, it avoids the impact of anti-retraction on subsequent processes, improves work efficiency and progress, further reduces labor costs, lowers expenses, and saves costs.

[0043] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of the present invention, and all such modifications and substitutions should be considered within the scope of protection of the present invention.
