Detailed Implementation

[0018] The present invention will now be described in detail with reference to the accompanying drawings and embodiments: like Figures 1-12 The diagram shows an embodiment of a flat-edged mold with multi-directional guidance provided by the present invention, including: an upper template 1 and a lower template 2 that are interlocked and fitted together, and a symmetrically distributed support frame 3. A movable frame 4 is movably provided inside the support frame 3 through an elastic element. An upper mold base 5 and a lower mold base 6 that are slidably fitted inside the movable frame 4 and interlocked with the ends of the upper template 1 and the lower template 2, respectively. It also includes a telescopic member 7 and a pressure plate 8. A connecting rod 9 is fixedly connected to the telescopic end of the telescopic member 7. A sliding frame 10 that slidably fits with the connecting rod 9 is fixedly connected to the middle of the pressure plate 8. A compression spring 11 is hung between the telescopic end of the telescopic member 7 and the pressure plate 8. A rotating plate 12 is rotatably connected to the lower mold base 6. A movable rod 13 that fits with the rotating plate 12 is rotatably connected to the end of the connecting rod 9. An arc-shaped plate 14 is fixedly connected to the upper mold base 5. The rotating plate 12 and the edge of the arc-shaped plate 14 are in abutting fit.

[0019] The elastic element includes a plug rod 15 that is fixed to the side of the movable frame 4 and passes through the movable frame 4. A first spring 16 is connected between the movable frame 4 and the support frame 3. Under the action of the rotating plate 12, the upper mold base 5 and the lower mold base 6 move up and down along the movable frame 4. In conjunction with the first spring 16, the movable frame 4 moves horizontally back and forth.

[0020] The movable frame 4 is rotatably connected to a rotating disk 17 that is fixed to the end of the first spring 16. The plug rod 15 is movably plugged into the rotating disk 17. The rotating disk 17 causes the movable frame 4 to tilt. During this process, the plug rod 15 can also rotate on its own when it moves back and forth.

[0021] The support frame 3 has a slot 18 at its edge, and the plug-in rod 15 has a fixing slot 19. The fixing slot 19 communicates and engages with the slot 18. The upper mold base 5 and the lower mold base 6 are rotatably connected to the ends of a protruding structure 28. The inner wall of the movable frame 4 has a limiting groove for sliding engagement with the protruding structure 28. In this application, when the upper mold plate 1 and the lower mold plate 2 are in a static state, an external plug-in plate (not shown in the figure) is simultaneously inserted into the slot 18 and the fixing slot 19, thereby stabilizing the positions of the upper mold plate 1 and the lower mold plate 2 and preventing them from moving.

[0022] It is worth noting that: the movable frame 4 is connected to the upper mold base 5 and the lower mold base 6 respectively with a second spring 20, and a plug ring 21 is fixedly connected to the edge of the rotating plate 12. The upper mold base 5 and the lower mold base 6 are provided with mutually cooperating semi-circular grooves 22. The plug ring 21 moves in the semi-circular groove 22. The installation of the upper template 1 and the lower template 2 is completed by plugging the plug ring 21 into the semi-circular groove 22. The plug ring 21 moves in the semi-circular groove 22 to ensure the stability of the upper template 1 and the lower template 2 and the rotation of the rotating plate 12.

[0023] In this application, two connecting rods 9 are connected and fixed by a fixing rod 23, and a guide plate 24 that cooperates with the pressure plate 8 is fixedly connected to the movable frame 4; a fork plate 29 is fixedly connected to the fixing rod 23, and the bottom end of the fork plate 29 is pressed against the top surface of the upper template 1. When the upper template 1 and the lower template 2 are in a static state, the fork plate 29 is pressed and fixed on the upper template 1 to ensure the stability of the upper template 1 and the lower template 2.

[0024] The rotating plate 12 is provided with a sliding groove 25 that slides with the movable rod 13. A reciprocating plate 26 is movably inserted into the rotating plate 12 and passes through the sliding groove 25. A third spring 27 is connected between the inner end of the reciprocating plate 26 and the movable rod 13. The outer end of the reciprocating plate 26 is pressed against the arc plate 14. The connecting rod 9 moves up and down. Through the cooperation between the movable rod 13 and the sliding groove 25, the rotating plate 12 rotates, thereby causing the upper mold base 5 and the lower mold base 6 to shake and drive the reciprocating plate 26 to move back and forth, thereby intermittently striking the arc plate 14 and further striking the upper mold base 5 (during this process, part of the insertion ring 21 is located in the semi-circular groove 22 on the upper mold base 5, and the other part of the insertion ring 21 is located in the semi-circular groove 22 on the lower mold base 6, thereby ensuring a stable connection between the upper mold base 5 and the lower mold base 6), thus facilitating the uniform and dense molding of the product.

[0025] Working principle: Regarding the installation of the upper template 1 and the lower template 2: Manually rotate the rotating plate 12 so that the rotating plate 12 is on top and the insertion ring 21 (semi-circular) is on the bottom, with the insertion ring 21 completely located in the semi-circular groove 22 inside the lower mold base 6; The upper mold base 5 and the lower mold base 6 are pressed together, and the upper template 1 and the lower template 2 are inserted and fixed. At this time, the two semi-circular grooves 22 are engaged.

[0026] Regarding shaking the upper mold plate 1 and the lower mold plate 2 to make the molded material uniform and dense: activate the telescopic component 7 (electric telescopic rod or pneumatic cylinder assembly), so that the telescopic end of the telescopic component 7 moves up and down reciprocally (the distance of the up and down reciprocating movement is limited), the connecting rod 9 moves up and down reciprocally, so that the top end of the movable rod 13 moves up and down, and the bottom end of the movable rod 13 moves back and forth in the sliding groove 25, thereby causing the rotating plate 12 to rotate. During the rotation of the rotating plate 12, part of the insertion ring 21 is located in the semi-circular groove 22 on the upper mold base 5, and the other part of the insertion ring 21 is located in the semi-circular groove 22 on the lower mold base 6, thereby ensuring a stable connection between the upper mold base 5 and the lower mold base 6 during the compaction process; The reciprocating rotating plate 12 allows the upper mold base 5 and the lower mold base 6, as well as the upper template 1 and the lower template 2, to move in the horizontal and vertical directions. Meanwhile, the movable frame 4 moves back and forth along the plug rod 15. Since the protruding structure 28 is rotated with the template and the lower template 2, it does not affect the rotation of the movable frame 4 at a certain angle. That is, when the plug rod 15 rotates, the rotating disk 17 rotates adaptively on the movable frame 4, which can also ensure that the upper mold base 5 and the lower mold base 6, as well as the upper template 1 and the lower template 2, can rotate at a certain angle. The reciprocating connecting rod 9, together with the sliding frame 10 and the compression spring 11, drives the pressure plate 8 to move up and down reciprocally. During this process, the pressure plate 8 will not press tightly against the top surface of the movable frame 4. The telescopic end of the telescopic component 7 moves up and down reciprocally, thereby driving the pressure plate 8 to move up and down. Under the action of the inclined guide plate 24, the pressure plate 8 rotates back and forth at a certain angle. The ends of the pressure plate 8 press against the guide plate 24 in an alternating manner, further enhancing the effect of the movable frame 4 moving back and forth along the direction of the plug-in rod 15. During the rotation of the rotating plate 12, the reciprocating plate 26 moves back and forth (the moving rod 13 moves along the sliding groove 25, promoting the reciprocating plate 26 to move back and forth along the rotating plate 12), and knocks the arc plate 14 at intervals, thereby vibrating the upper mold base 5. When the reciprocating plate 26 is tilted, the insertion ring 21 is simultaneously located in the two semi-circular grooves 22, ensuring that the upper mold base 5 and the lower mold base 6 are stably connected when the upper mold base 5 is vibrating. During this process, the bottom of the fork plate 29 will not come into contact with the upper template 1.

[0027] Regarding stabilizing the upper template 1 and lower template 2, and placing the molded object in a static position to facilitate stable molding: the telescopic end of the telescopic component 7 moves downward (the downward movement distance is greater than the above-mentioned up-and-down reciprocating movement distance), so that the pressure plate 8 tightly presses against the movable frame 4, thereby restricting the movable frame 4 and preventing it from rotating at an angle, thus stabilizing the movable frame 4; and the bottom end of the fork plate 29 presses against the upper template 1, stabilizing the upper template 1 and lower template 2, thereby ensuring a static state.
