Description

Technical Field

[0001] This utility model relates to the field of mold technology, specifically to an injection mold that facilitates guiding and pushing materials. Background Technology

[0002] Injection molds are key equipment for molding and processing plastic products. They are formed by injecting molten plastic into the mold cavity and then cooling and solidifying it to form a product of a specific shape. The core structure of injection molds includes two main parts: the fixed mold and the moving mold. However, existing injection molds still have certain defects in use.

[0003] For example, the injection mold proposed in application number CN202323039755.6, which facilitates material ejection, includes a support frame. Hydraulic cylinders are symmetrically installed on the top inner wall of the support frame. An upper mold is installed on the telescopic end of the hydraulic cylinders. An ejection assembly is symmetrically installed on the top of the upper mold. The ejection assembly is used to eject the injection molded part adhering to the mold cavity of the upper mold. The ejection assembly includes a sleeve. The sleeve has symmetrically opened limit grooves inside. A through hole is opened through the bottom inner wall of the sleeve. An ejector rod is installed through the top of the sleeve. In actual use, this injection mold ejects the injection molded product by manually pushing the material, and cannot use the kinetic energy generated by the moving mold during the movement to achieve the material ejection and demolding work, which reduces the use effect. Moreover, the manual pushing method poses a safety hazard. In addition, the material ejection structure and the moving mold in this injection mold are fixedly connected, which makes it inconvenient to disassemble and maintain.

[0004] Therefore, we propose an injection mold that facilitates guiding and pushing the material, in order to solve the problems mentioned above. Utility Model Content

[0005] The purpose of this invention is to provide an injection mold that facilitates material pushing and ejection, thereby solving the problems mentioned in the background art, such as the inability to utilize the kinetic energy generated during the movement of the moving mold to achieve material pushing and demolding, and the inconvenience of disassembly and maintenance due to the fixed connection method.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an injection mold that facilitates guiding and pushing materials, comprising a fixed mold and a moving mold, wherein a first fixing plate is fixedly installed on the front side of the fixed mold, an injection port is provided at the center of the fixed mold and the first fixing plate, and docking rods are symmetrically installed at both ends of the rear side of the fixed mold, and docking grooves are symmetrically provided at both ends of the moving mold;

[0007] The rear side of the moving mold is symmetrically and movably connected to a positioning seat, and the rear end of the positioning seat is connected to a second fixing plate.

[0008] The module positioning mechanism is connected between the second fixed plate, the positioning seat and the moving mold for the combined connection of the three.

[0009] The guide and push mechanism is installed inside the positioning seat to cooperate with the moving mold for pushing and demolding.

[0010] Preferably, the positions of the connecting rod and the connecting groove correspond one-to-one, and the connecting rod and the connecting groove are movably inserted into each other.

[0011] The above-mentioned structural design enables rapid and precise alignment of the fixed mold and the moving mold, ensuring accurate connection of the mold cavity during injection molding.

[0012] Preferably, the module positioning mechanism includes symmetrically arranged insertion slots at both ends of the front side of the second fixed plate, and the insertion slots are tightly fitted and connected to the rear end of the positioning seat.

[0013] The above-mentioned structural design allows for preliminary positioning of the positioning seat and the second fixing plate, reducing the difficulty of alignment during subsequent adjustment screw fixing and improving assembly efficiency. At the same time, the tight fit enhances the stability between the second fixing plate and the positioning seat, preventing loosening during mold operation.

[0014] Preferably, the module positioning mechanism further includes positioning bearings symmetrically installed at the middle of both ends of the positioning seat. The inner ring of the positioning bearing is connected to an adjusting screw, and the outer ring of the adjusting screw is threaded with a snap-fit ​​plate. The snap-fit ​​plate has symmetrically opened limit holes inside, and a limit rod passes through the limit holes. The inner end of the limit rod is fixedly connected to the positioning seat. The snap-fit ​​plate is slidably connected to the limit rod through the limit holes. The two ends of the moving mold have front snap-fit ​​grooves, and the two ends of the second fixed plate have rear snap-fit ​​grooves. The snap-fit ​​plate is engaged with the front snap-fit ​​grooves and the rear snap-fit ​​grooves.

[0015] The above-mentioned structural design allows for rapid engagement and disengagement between the second fixed plate, positioning seat, and moving mold by rotating the adjusting screw to drive the snap-fit ​​plate. Compared with traditional fixed connection methods, this greatly simplifies the disassembly and maintenance process. The cooperation between the limiting rod and the limiting hole restricts the movement direction of the snap-fit ​​plate, ensuring the stability of the snap-fit ​​process.

[0016] Preferably, the guiding and pushing mechanism includes a groove formed inside the positioning seat, and fixed rods are installed at equal intervals inside the groove. A connecting plate is slidably sleeved on the outer ring of the fixed rods. A spring is sleeved on the outer ring of the fixed rods behind the connecting plate. The connecting plate and the second fixed plate form a telescopic structure through the spring.

[0017] With the above-mentioned structural design, the spring is compressed and stores kinetic energy during the docking process between the moving mold and the fixed mold. When the moving mold completes the injection return stroke, the spring releases kinetic energy to push the connecting plate and the ejector assembly forward, realizing the ejection and demolding by using the kinetic energy generated by the movement of the moving mold. No additional power source is required, reducing energy consumption and improving demolding efficiency.

[0018] Preferably, the guiding and pushing mechanism further includes a pushing plate fixedly installed between the two connecting plates. A positioning plate is fixedly installed on the front side of the pushing plate by bolts. Linkage rods are symmetrically installed at both ends of the positioning plate. An ejector pin is fixedly installed inside the positioning plate. The linkage rods and ejector pins are slidably connected to the moving mold.

[0019] With the above-mentioned structural design, the pusher plate, positioning plate, linkage rod and ejector pin form a linkage pusher assembly, which moves synchronously under the drive of the spring to ensure uniform force on the product and effectively avoid product deformation caused by uneven pusher. The through sliding connection between the linkage rod and the moving mold plays a guiding role and further improves the stability of the pusher process.

[0020] Compared with the prior art, the beneficial effects of this utility model are: the injection mold that facilitates guiding and pushing materials;

[0021] 1. During the docking process between the moving mold and the fixed mold, the spring is compressed to store kinetic energy. When the injection molding is completed and the moving mold returns, the spring releases the kinetic energy to drive the ejector assembly. Ejection and demolding can be achieved without an additional power source, which significantly reduces energy consumption. At the same time, the ejector assembly moves synchronously under the drive of the spring to ensure uniform force on the product, avoid deformation caused by uneven ejection, and improve demolding efficiency and product quality.

[0022] 2. In terms of disassembly and maintenance, the optimization of the module positioning mechanism greatly improves the shortcomings of the traditional fixed connection method. By adjusting the screw, the snap-fit ​​plate and the limiting structure, the snap-fit ​​and separation between the second fixed plate, the positioning seat and the moving mold can be quickly realized, simplifying the disassembly process. With the initial positioning and tight fit of the insertion slot, it not only improves the assembly efficiency, but also enhances the stability between the components, reduces the risk of loosening during mold operation, and makes the maintenance and repair of the mold more convenient and efficient, effectively extending the service life of the mold.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figure 1-5 This utility model provides a technical solution: an injection mold that facilitates guiding and pushing materials, including a fixed mold 1 and a moving mold 5. A first fixed plate 2 is fixedly installed on the front side of the fixed mold 1. An injection port 3 is opened in the center of the fixed mold 1 and the first fixed plate 2. A connecting rod 4 is symmetrically installed at both ends of the rear side of the fixed mold 1. A connecting groove 6 is symmetrically opened at both ends of the moving mold 5. The positions of the connecting rod 4 and the connecting groove 6 correspond one-to-one. The connecting rod 4 and the connecting groove 6 are movably inserted into each other.

[0031] In the initial stage of mold operation, the fixed mold 1 and the first fixed plate 2 are securely installed on the front template of the injection molding machine, while the moving mold 5 and the second fixed plate 8 are in standby mode. At this time, the connecting rod 4 and the connecting groove 6 are separated from each other. When the injection molding process starts, the moving mold 5 is driven to move forward and close with the fixed mold 1. During this process, the connecting rods 4, which are symmetrically distributed on the rear side of the fixed mold 1, gradually insert into the connecting groove 6 as the moving mold 5 continues to move forward, thanks to their precise positional relationship with the connecting grooves 6 at both ends of the moving mold 5 and their movable insertion design characteristics. The two work together to achieve precise alignment of the center lines of the fixed mold 1 and the moving mold 5.

[0032] A positioning seat 7 is symmetrically and movably connected to the rear side of the moving mold 5. A second fixing plate 8 is connected to the rear end of the positioning seat 7. A module positioning mechanism is connected between the second fixing plate 8, the positioning seat 7, and the moving mold 5 for assembly connection. The module positioning mechanism includes insertion slots 9 symmetrically opened at both ends of the front side of the second fixing plate 8. The insertion slots 9 are tightly fitted to the rear end of the positioning seat 7. The module positioning mechanism also includes positioning bearings 10 symmetrically installed at the middle of both ends of the positioning seat 7. The inner ring of the positioning bearing 10 is connected to... There is an adjusting screw 11, and the outer ring of the adjusting screw 11 is threaded with a snap-fit ​​plate 12. The snap-fit ​​plate 12 has symmetrical limit holes 13 inside, and a limit rod 14 passes through the limit holes 13. The inner end of the limit rod 14 is fixedly connected to the positioning seat 7. The snap-fit ​​plate 12 is slidably connected to the limit rod 14 through the limit holes 13. The two ends of the moving mold 5 have front snap-fit ​​grooves 15, and the two ends of the second fixed plate 8 have rear snap-fit ​​grooves 16. The snap-fit ​​plate 12 is engaged with the front snap-fit ​​grooves 15 and the rear snap-fit ​​grooves 16.

[0033] In the above-mentioned structure design, during the assembly process, the initial connection between the positioning seat 7 and the second fixing plate 8 relies on the precise fit of the insertion slot 9. The rear end of the positioning seat 7 is aligned with the insertion slot 9 on the front side of the second fixing plate 8 and pushed in. The tightly fitting structure of the two forms a pre-positioning, which quickly determines the relative position and reduces the subsequent installation and debugging time.

[0034] When further fixing, by rotating the adjusting screw 11, the positioning bearing 10 is used to reduce the rotation resistance of the screw, and at the same time, the snap-fit ​​plate 12 with the outer ring threaded sleeve moves along the limiting rod 14. Due to the cooperation between the limiting hole 13 and the limiting rod 14, the snap-fit ​​plate 12 can only move in a straight line to avoid deviation. As the adjusting screw 11 rotates, the snap-fit ​​plate 12 gradually moves towards the moving mold 5 and the second fixed plate 8 until it is embedded in the front snap-fit ​​groove 15 at both ends of the moving mold 5 and the rear snap-fit ​​groove 16 at both ends of the second fixed plate 8, forming a stable connection whole.

[0035] When disassembly and maintenance are required, rotate the adjusting screw 11 in the opposite direction to retract the snap-fit ​​plate 12 along the limit rod 14, so that it is disengaged from the front snap-fit ​​groove 15 and the rear snap-fit ​​groove 16. After the snap-fit ​​plate 12 is completely disengaged, the second fixing plate 8, the positioning seat 7 and the moving mold 5 can be easily separated. Compared with the traditional bolt fixing method, the disassembly time is significantly shortened.

[0036] The guide and push mechanism is installed inside the positioning seat 7 to cooperate with the moving mold 5 for pushing and demolding. The guide and push mechanism includes a slide groove 17 opened inside the positioning seat 7. Fixed rods 18 are installed at equal intervals inside the slide groove 17. A connecting plate 19 is slidably sleeved on the outer ring of the fixed rods 18. A spring 20 is sleeved on the outer ring of the fixed rods 18 on the rear side of the connecting plate 19. The connecting plate 19 and the second fixed plate 8 form a telescopic structure through the spring 20. The guide and push mechanism also includes a push plate 21 fixedly installed between the two connecting plates 19. A positioning plate 22 is fixedly installed on the front side of the push plate 21 by bolts. Linkage rods 23 are symmetrically installed at both ends of the positioning plate 22. Ejector pins 24 are fixedly installed inside the positioning plate 22. The linkage rods 23 and ejector pins 24 are slidably connected to the moving mold 5.

[0037] In the above structure design, during the mold closing stage, the moving mold 5 moves forward and docks with the fixed mold 1. During this process, the moving mold 5 presses the positioning plate 22 and the push plate 21 through the linkage rod 23, thereby driving the connecting plate 19 to slide backward along the fixed rod 18, compressing the spring 20 sleeved on the fixed rod 18. After the spring 20 is compressed, it stores elastic potential energy. At the same time, under the guidance and constraint of the slide groove 17 and the fixed rod 18, the connecting plate 19 ensures that the movement direction is stable and avoids deviation.

[0038] After injection molding is completed, the mold opening stage begins. The moving mold 5 moves backward to release the pressure on the linkage rod 23. At this time, the compressed spring 20 begins to release its elastic potential energy, pushing the connecting plate 19 forward. Since the ejector plate 21 is fixedly installed between the two connecting plates 19, the movement of the connecting plate 19 drives the ejector plate 21 to move synchronously. The positioning plate 22, linkage rod 23 and ejector pin 24 on the front side of the ejector plate 21 form a linkage assembly. As the ejector plate 21 moves, the linkage rod 23 and ejector pin 24 slide forward along the through hole of the moving mold 5. The ejector pin 24 accurately presses the product and pushes it out of the mold cavity smoothly, realizing the demolding action.

[0039] This completes a series of tasks. The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0040] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
