Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0032] With reference to Figure 1 , Figure 3 and Figure 5 An embodiment provided by the utility model: a buckle injection mold capable of rapid demolding, comprising a base 1, the top of the base 1 is fixedly connected with a support frame 2, the top of the support frame 2 is installed with a hydraulic cylinder 3, the output end of the hydraulic cylinder 3 is fixedly connected with an upper die 4, the top of the base 1 is fixedly connected with a lower die 5, the inside upper side of the lower die 5 is provided with a forming cavity 6, the inner wall of the lower die 5 is fixedly connected with a baffle 7, the forming cavity 6 is located directly above the baffle 7, the inner wall of the lower die 5 is fixedly connected with a guide column 8, the outer side of the guide column 8 is slidably connected with a sliding block 9, the top of the sliding block 9 is rotatably connected with a connecting rod 10, the top of the connecting rod 10 is rotatably connected with a top plate 11, the outer side of the top plate 11 is slidably connected to the inner wall of the baffle 7, the outer side of the guide column 8 is sleeved with a spring I 12, one side of the sliding block 9 close to the spring I 12 is fixedly connected with a pull rope 13, the bottom of the upper die 4 is fixedly connected with a sealing ring 18, the top of the lower die 5 is provided with a sealing groove 19.

[0033] Specifically, the support frame 2 serves to connect the base 1 and the hydraulic cylinder 3, enhancing the overall integrity of the entire mold structure. The hydraulic cylinder 3 serves as a power source, providing stable driving force for the up-and-down movement of the upper mold 4. The movement speed and position of the upper mold 4 can be accurately controlled, ensuring the accuracy and efficiency of mold closing and opening. The upper mold 4 and the lower mold 5 together constitute the key part of injection molding. Their shape and structure determine the shape and size of the injection-molded part. The molding cavity 6 contains the injection material during the injection process and solidifies the injection-molded part after cooling. The baffle 7 provides guidance and limiting function for the sliding of the top plate 11, ensuring that the top plate 11 can move vertically upward during demolding. The guide column 8 provides precise guidance for the sliding of the slider 9, ensuring that the slider 9 can stably move in the designated direction during demolding. The slider 9 converts the pulling force of the pull rope 13 into the upward thrust of the top plate 11 through cooperation with the connecting rod 10. The connecting rod 10 serves to connect the slider 9 and the top plate 11, converting the linear motion of the slider 9 into the vertical upward motion of the top plate 11. The top plate 11 directly contacts and loosens the injection-molded part during demolding. During demolding, the spring 12 is compressed, storing elastic potential energy. When the injection-molded part is ejected, the elastic force of the spring 12 can quickly reset the slider 9, preparing for the next injection and demolding operation. When the upper mold 4 rises, the pull rope 13 pulls the slider 9 to slide along the guide column 8. The design of the pull rope 13 is simple and reliable, which can effectively transmit power. The sealing ring 18 and the sealing groove 19 form a sealing structure to prevent leakage of the injection material during the injection process. It ensures the stability of the injection pressure and improves the quality and precision of the injection-molded part.

[0034] Referring to Figure 1 , Figure 4 and Figure 6 , the outer part of the upper mold 4 is provided with a reinforcing assembly for reinforcing the connection between the sealing ring 18 and the sealing groove 19. The reinforcing assembly includes four mounting shells 22, which are fixedly connected to the outer sides of the upper mold 4 on both sides. The inner wall of the mounting shell 22 is slidably connected with the movable plate 23. One end of the movable plate 23 is fixedly connected with the clamping column 24. The other end of the movable plate 23 is fixedly connected with the connecting rod 25. The end of the connecting rod 25 away from the movable plate 23 is fixedly connected with the pull plate 26. The outer side of the connecting rod 25 is sleeved with the spring 17. The outer sides of the sealing ring 18 are provided with two clamping grooves 21. The outer sides of the lower mold 5 are provided with two connecting holes 20. The shapes of the clamping columns 24 are matched with the shapes of the connecting holes 20 and the clamping grooves 21. The outer sides of the plurality of clamping columns 24 are slidably connected with the inner walls of the corresponding connecting holes 20. The outer sides of the plurality of clamping columns 24 are insertedly matched with the inner walls of the corresponding clamping grooves 21. One end of each of the plurality of springs 17 is fixedly connected with one side of the corresponding movable plate 23. The other end of each of the plurality of springs 17 is fixedly connected with the inner wall of the corresponding mounting shell 22.

[0035] Specifically, the installation shell 22 provides installation and accommodation space for components such as the movable plate 23, the clamping column 24, and the connecting rod 25. The movable plate 23 connects the clamping column 24 and the connecting rod 25, and plays a role in force transmission. The clamping column 24 is inserted into the connecting hole 20 and the clamping groove 21 to reinforce the connection of the sealing ring 18 with the sealing groove 19. During the injection molding process, the clamping column 24 can prevent the sealing ring 18 from being pulled out of the sealing groove 19, ensuring the stability of the sealing performance. The connecting rod 25 connects the movable plate 23 and the pull plate 26, and transmits the external force of the pull plate 26 to the movable plate 23, thereby controlling the movement of the clamping column 24. By pulling the pull plate 26, the movement of the connecting rod 25, the movable plate 23, and the clamping column 24 can be controlled. During the mold closing process, the elastic force of the spring 2 17 pushes the movable plate 23, causing the clamping column 24 to be inserted into the connecting hole 20 and the clamping groove 21.

[0036] Referring to Figure 1 and Figure 3 , the shape of the sealing ring 18 matches the shape of the sealing groove 19, and the outer side of the sealing ring 18 is inserted into the inner wall of the sealing groove 19.

[0037] Specifically, the shape of the sealing ring 18 matches and is inserted into the shape of the sealing groove 19, which can form a good sealing effect during the injection molding process, preventing the leakage of injection material from the joint of the upper and lower molds 5. This helps to ensure the stability of the injection molding pressure, improve the quality and precision of the injection molded parts, reduce the waste of raw materials, and also avoid potential safety hazards and environmental pollution caused by leakage.

[0038] Referring to Figure 3 and Figure 5 , one end of the spring 1 12 is fixedly connected to the outer side of the sliding block 9, the other end of the spring 1 12 is fixedly connected to the inner wall of the lower mold 5, the outer side of the guide column 8 is fixedly connected with the stop block 14, and the outer side of the stop block 14 is in contact with the outer side of the sliding block 9.

[0039] Specifically, the spring 1 12 is connected between the sliding block 9 and the inner wall of the lower mold 5. During the demolding process, when the pull rope 13 pulls the sliding block 9 to slide along the guide column 8, the spring 1 12 is compressed and stores elastic potential energy. After the injection molded part is ejected, the elastic force of the spring 1 12 can quickly reset the sliding block 9, preparing for the next injection and demolding operation, and improving the working efficiency of the mold. The stop block 14 is fixed to the outer side of the guide column 8 and in contact with the outer side of the sliding block 9, which can effectively prevent the sliding block 9 from sliding off the guide column 8. It ensures that the sliding block 9 always moves within the specified range, ensuring the stability and reliability of the demolding operation. The stop block 14 is fixed to the outer side of the guide column 8 and in contact with the outer side of the sliding block 9, which can effectively prevent the sliding block 9 from sliding off the guide column 8. It ensures that the sliding block 9 always moves within the specified range, ensuring the stability and reliability of the demolding operation.

[0040] Referring to Figure 1 andFigure 2 The upper die 4 is fixedly connected with guide blocks 15 on both sides, and the base 1 is fixedly connected with guide rods 16 on both sides of the top. The inner through holes of the two guide blocks 15 are respectively and slidably connected with the outer sides of the corresponding guide rods 16.

[0041] Specifically, during the closing and opening of the mold, the guide blocks 15 move along the guide rods 16, which can ensure the vertical and stable movement of the upper die 4. This helps to ensure the accurate alignment of the upper die 4 and the lower die 5, improve the precision of the mold closing, and prevent the quality problems of the injection molded parts caused by the deviation of the upper die 4.

[0042] Working principle: start the hydraulic cylinder 3, and the output end of the hydraulic cylinder 3 pushes the upper die 4 to move downward. The guide blocks 15 on both sides of the upper die 4 slide along the guide rods 16 on the top of the base 1, ensuring the vertical and stable descent of the upper die 4. The upper die 4 gradually approaches the lower die 5, and the sealing ring 18 at the bottom of the upper die 4 is aligned with the sealing groove 19 at the top of the lower die 5. Then pull the pull plate 26, the pull plate 26 drives the connecting rod 25 to move, and then drives the movable plate 23 to move, and drives the clamping column 24 to move, and separates from the inner wall of the clamping groove 21, and compresses the second spring 17, and then the sealing ring 18 is inserted into the sealing groove 19 to form a sealing structure to prevent leakage of the raw materials during injection molding. Then loosen the pull plate 26, and the movable plate 23 is moved under the elastic action of the second spring 17, so that the clamping column 24 slides on the inner wall of the connecting hole 20, and then is inserted into the clamping groove 21, and the connection of the sealing ring 18 and the sealing groove 19 is reinforced, further improving the sealing performance. And the injection material is injected into the molding cavity 6 on the upper side inside the lower die 5, which is filled with the molding cavity 6 under the action of pressure, and gradually cools and forms.

[0043] When the clasp injection molded part is cooled and formed, repeat the above steps to pull the pull plate 26 to make the clamping column 24 separate from the inner wall of the connecting hole 20 and the clamping groove 21, start the hydraulic cylinder 3 to drive the upper die 4 to move upward, and after the upper die 4 is separated from the lower die 5, the injection molded part is left in the molding cavity 6 of the lower die 5. Then pull the drawstring 13, which will pull the sliding block 9 to slide along the guide column 8. The sliding block 9 compresses the first spring 12 during sliding, and at the same time, the abutment rod 10 on the top of the sliding block 9 drives the top plate 11 to slide upward on the inner wall of the baffle 7. The upward movement of the top plate 11 ejects part of the clasp injection molded part in the molding cavity 6, effectively breaking the adhesion between the clasp injection molded part and the inner wall of the molding cavity 6, and generating a certain gap between them, greatly reducing the difficulty of subsequent demolding, thus achieving rapid demolding. When the clasp injection molded part is ejected, the elastic force of the first spring 12 resets the sliding block 9, and the stop block 14 provides a limiting action for the sliding block 9, which can effectively prevent the sliding block 9 from sliding off the guide column 8.

[0044] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and is not intended to limit the present application, although the foregoing embodiments of the present application has been described in detail, for the skilled in the art, it still can be modified, or for part of the technical features of the equivalent replacement, the spirit and principles of the present application, made any modification, equivalent replacement, improvement, etc., should be included within the scope of the present application.
