Description

Technical Field

[0001] This utility model relates to the field of graphite mold technology, specifically to a graphite product mold that is easy to demold. Background Technology

[0002] In recent years, the mold industry has developed rapidly. Graphite materials, new processes, and an increasing number of mold factories have been constantly impacting the mold market. Graphite, with its excellent physical and chemical properties, has gradually become the preferred material for mold making.

[0003] The existing authorized announcement number CN218985876U discloses a graphite mold with a rapid demolding structure, belonging to the field of graphite mold technology. It includes a lower mold base with a mold cavity inside. This utility model designs a rapid demolding mechanism composed of a telescopic column, a spring, a magnetic block, an electromagnet, a threaded cavity, and a locking screw. During processing, the electromagnet is energized to attract the magnetic block, thereby causing the top plate to move downwards and the telescopic column and spring to compress. Then, the locking screw is screwed into the threaded cavity in the top plate to fix it. At this time, the electromagnet can be de-energized, and the top plate is limited and fixed by the locking screw. Then processing is carried out. After processing is completed, the locking screw is reversed to separate it from the threaded cavity in the top plate, thus releasing the fixation. At this time, the spring's rebound force can quickly eject the processed workpiece, enabling rapid demolding. This not only facilitates operation but also ensures the processing efficiency of the mold and improves the practicality of the device.

[0004] The above technical solution utilizes an electromagnet to attract a magnetic block downwards, thereby causing the top plate to move downwards and compressing the telescopic column and spring. A locking screw is then screwed into the threaded cavity within the top plate to fix it in place. However, the electromagnet's magnetic attraction will decrease over time, and fixing the top plate by turning the locking screw requires more time and effort from the workers, increasing the workload of demolding the graphite material. Therefore, we provide a graphite product mold that facilitates demolding. Utility Model Content

The top plate will be released from the fixed limit, and the telescopic spring and the spring will lose the squeezing force, thereby releasing the elastic force to push the top plate to move upward. As the top plate rises, the graphite material in the lower mold base can be lifted and demolded, reducing the workload of the demolding staff.

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0023] This utility model provides a technical solution: such as Figures 1-4As shown, in this embodiment, a graphite product mold that facilitates demolding includes: a demolding mechanism 1, which includes a lower mold base 11. A top plate 13 is provided inside the lower mold base 11. Two sliders 14 are provided on both sides of the top plate 13. Limiting grooves 15 are provided on both sides of the inner wall of the lower mold base 11 near the sliders 14. The outer side of the top plate 13 is slidably connected to the inner wall of the lower mold base 11. Two sliders 14 are fixedly connected to both sides of the top plate 13. The outer side of the sliders 14 is slidably connected to the inner wall of the limiting grooves 15. Pull rods 17 are provided in slots on both sides of the top of the lower mold base 11. Fixing grooves 18 are provided at both ends of the other two sides of the top plate 13. Baffles 19 are provided at both ends of both sides of the outer surface of the lower mold base 11. The bottom ends of the two pull rods 17 pass through the slots on both sides of the top of the lower mold base 11 and are fixedly connected to the top of the sliders 14. The side of the baffle 19 closest to the lower mold base 11 contacts the outside of the lower mold base 11. All four baffles 19 are close to the lower mold base 11. Each of the four movable rods 110 is provided on one side, and each of the four movable rods 110 is provided with a return spring 111. Each of the four movable rods 110 is provided with a fixed block 112 at the end away from the platen 19. One end of the movable rod 110 is movably connected to the inside of the platen 19, and the other end of the movable rod 110 passes through the slot opened on one side of the lower mold base 11 and the inner ring of the return spring 111 and is fixedly connected to one end of the fixed block 112. Each of the four corners at the bottom of the top plate 13 is provided with a telescopic return mechanism. The other end of the spring 113 and the fixing block 112 are engaged with the inner wall of the fixing groove 18. The top of the telescopic spring 113 is fixedly connected to the bottom of the top plate 13, and the bottom of the telescopic spring 113 is fixedly connected to the bottom side of the inner wall of the lower mold base 11. Four spring pieces 115 are provided at the bottom of the top plate 13. The top of the spring pieces 115 is fixedly connected to the bottom of the top plate 13, and the bottom of the spring pieces 115 is fixedly connected to the bottom side of the inner wall of the lower mold base 11. A positioning mechanism 2 is provided at the top of the lower mold base 11.

[0024] In this embodiment, when the operator needs to use the graphite mold, they can first move the lever 19. When the lever 19 is moved, it will press against the outside of the lower mold base 11, thus opening the angle of the lever 19. At the same time, the lever 19 will pull the movable rod 110 and the fixed block 112 towards the lever 19, and the fixed block 112 will move into the slot opened in the lower mold base 11. During the movement, the return spring 111 will be pressed, and the return spring 111 will contract and deform. Then, the operator can press the pull rod 17 to make the slider 14 slide down in the limiting slide groove 15, and the top plate 13 will move downward in the lower mold base 11. When the top plate 13 descends, it will press the telescopic return member 113 and the spring piece 115, so the spring piece 115 and the telescopic return member 113 will contract and deform. When the mold descends to its limit position, the fixing groove 18 and the fixing block 112 will remain on the same horizontal plane. The operator can release the lever 19, and the return spring 111 will release its elastic force to push the fixing block 112 into the fixing groove 18. Then the top plate 13 will be limited and fixed inside the lower module. The operator can then use the mold to process the graphite material. When it is necessary to demold the graphite material in the lower mold base 11, the lever 19 can be moved again. Then, using the lever 19, the movable rod 110 and the fixing block 112, the fixing block 112 will be disengaged from the fixing groove 18 opened in the top plate 13. The top plate 13 will be released from its fixed position. At the same time, the telescopic spring 113 and the spring piece 115 will lose their compressive force and release their elastic force to push the top plate 13 upward. As the top plate 13 rises, the graphite material in the lower mold base 11 can be lifted and demolded.

[0025] like Figure 1 and Figure 4 As shown, the positioning mechanism 2 includes a cover plate 21, an upper mold base 22 is fixedly connected to the bottom of the cover plate 21, and positioning posts 23 are fixedly connected to the four corners of the bottom of the cover plate 21. Positioning grooves 24 are opened at the four corners of the top of the lower mold base 11, and the bottom of the positioning posts 23 is slidably connected in the positioning grooves 24.

[0026] In this embodiment, in order to ensure that the upper mold base 22 can be fully connected to the lower mold base 11, the connection process between the upper mold base 22 and the lower mold base 11 can be quickly completed by the positioning pin 23 and the positioning groove 24. This not only improves the assembly accuracy of the entire mold, but also improves the overall production efficiency.

[0027] This utility model provides a graphite product mold that facilitates demolding. The specific working principle is as follows:

[0028] When workers need to process graphite molds, they can first move lever 19. Lever 19 is ingeniously designed; when it is moved, it makes contact with the outside of the lower mold base 11. Simultaneously, lever 19 pulls the movable rod 110 and the fixed block 112 towards lever 19. This design creates a linkage mechanism between lever 19, movable rod 110, and fixed block 112. When lever 19 is moved, movable rod 110 and fixed block 112 also move accordingly. During this process, fixed block 112 will... The slide block 14 will move into the slot provided in the lower mold base 11. This slot is designed to ensure that the fixing block 112 can be recessed during movement. During the movement of the fixing block 112, the return spring 111 will also be compressed. This compression will cause the return spring 111 to contract and deform, providing the necessary force for subsequent operations. Next, the operator can press the pull rod 17 to make the slide block 14 slide down in the limiting slide groove 15. As the slide block 14 slides down, the top plate 13 will also move downward in the lower mold base 11. This movement will affect the telescopic return spring. The compression force generated by 113 and spring 115 causes them to contract and deform. When the top plate 13 descends to its limit position, the fixing groove 18 and the fixing block 112 will remain on the same horizontal plane. This design ensures that the fixing block 112 can be accurately engaged in the fixing groove 18, thereby ensuring that the top plate 13 can be stably fixed inside the lower module. At this time, the operator can release the lever 19, and the return spring 111 will release its elastic force to push the fixing block 112 into the fixing groove 18. When it is necessary to demold the graphite material in the lower mold base 11, The operator can move the lever 19 again. This time, moving the lever 19 will utilize the linkage between the lever 19, the movable rod 110 and the fixed block 112 to make the fixed block 112 disengage from the fixed groove 18 opened in the top plate 13. As the fixed block 112 disengages, the top plate 13 will also be released from its fixed limit. At the same time, the telescopic spring 113 and the spring sheet 115 will also lose their compressive force, thereby releasing the elastic force to push the top plate 13 upward. This movement will cause the top plate 13 to gradually rise, eventually lifting the graphite material in the lower mold base 11 for demolding.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
