It should be understood that the following text is only used to describe one or several specific implementations of the utility model, and does not strictly limit the protection scope of the specific request of the utility model.

[0027] like Figure 1-4 As shown, an automatic mold removal device includes a mold removal top casing 1, a mold support plate 2 is fixedly installed on one side of the lower surface of the mold removal top casing 1, a main dismantling frame 3 is movably assembled at a position on the lower surface of the mold removal top casing 1 and opposite to the mold support plate 2, and side dismantling frames 4 are symmetrically and movably assembled on the other two sides of the lower surface of the mold removal top casing 1, and a nut removal mechanism 5 for removing nuts is assembled at the bottom of the main dismantling frame 3 and the side dismantling frame 4.

[0028] Refer to the attached Figure 2 and Figure 3 A main rail 101 is fixedly assembled on one side of the mold removal top casing 1, and side rails 102 perpendicular to the main rail 101 are fixedly assembled on both sides of the mold removal top casing 1. A slider 1 301 slidably installed inside the main rail 101 is fixedly arranged on the top of the main dismantling frame 3, and a slider 2 401 slidably installed inside the side guide rail 102 is fixedly arranged on the top of the side dismantling frame 4. A cylinder 103 is fixedly installed inside the mold removal top casing 1, and the telescopic output end of the cylinder 103 is fixedly connected to the slider 1 301.

[0029] Refer to the attached Figure 2 and Figure 3, a transmission arm 104 is symmetrically installed on both sides of the main rail 101 inside the mold removal top casing 1, and a driving arm 105 is symmetrically installed on the top of the transmission arm 104. The driving arm 105 is sequentially provided with a middle straight groove 107 and an end straight groove 106 from the transition point to the end; support rods 302 are fixedly connected to both sides of the top of the slider 1 301, and a sliding sleeve 303 is movably sleeved on the outer surface of the end of the support rod 302, and a top rod 1 304 is fixedly connected to the top of the sliding sleeve 303, and the top rod 1 304 is movably inserted into the inside of the middle straight groove 107, and the end of the transmission arm 104 is rotatably connected to the sliding sleeve 303; the top of the slider 2 401 is fixedly connected to the top rod 2 402 movably inserted into the inside of the end straight groove 106.

[0030] Refer to the attached Figure 2 and Figure 3 The bottom two sides of the main dismantling frame 3 are symmetrically fixedly connected with pipe racks 305, and the ends of the pipe racks 305 are telescopically plugged with inner racks 306, and the outer walls of the ends of the pipe racks 305 are screwed with fixing screws 307 for fixing the inner racks 306. The bottom structure of the main dismantling frame 3 is the same as the bottom structure of the side dismantling frame 4, and the nut removal mechanism 5 is fixedly installed at the end of the inner rack 306.

[0031] According to the above structure, the demoulding top casing 1 is controlled to move downward by the lifting mechanism, one side of the mold will fit with the mold support plate 2, and then the cylinder 103 is started to shrink, the slider 301 will move along the main rail 101, and the main demoulding frame 3 will drive the nut removal mechanism 5 at both ends of the bottom to move toward the mold; while the slider 301 moves, the support rod 302 will move along, and under the connection of the transmission rotating arm 104, the sliding sleeve 303 will simultaneously move along the support rod 302 toward the slider 301 direction, because the top rod 304 on the top of the slider 301 is inserted into the middle straight groove 107, so the driving rotating arm 105 will be driven to rotate at the same time, and because the slider 40 The top push rod 402 at the top is inserted into the end straight groove 106. While driving the rotating arm 105 to rotate, the slider 401 will be driven to move along the side guide rail 102. Finally, the side disassembly frame 4 will simultaneously drive the nut removal mechanisms 5 at both ends of its bottom to move toward the mold, and finally the main disassembly frame 3 and the side disassembly frame 4 will move toward the mold together. This mechanism can realize that only one cylinder 103 drives all the nut removal mechanisms 5 to move toward the mold together, so that all the nuts used to assemble the mold can be disassembled in a short time, thereby quickly completing the disassembly work between the templates of the rectangular mold, reducing the number of electrical equipment, and saving the space occupied by the mechanism.

[0032] Refer to the attached Figure 4The nut removal mechanism 5 includes a motor 501, and the end of the output shaft of the motor 501 is fixedly connected to a removal tube 502. A nut abutment tube 503 is rotatably installed inside the end of the removal tube 502. A hexagonal groove 504 is opened at the end of the nut abutment tube 503, and a magnet 505 is fixedly installed on the inner wall of the hexagonal groove 504.

[0033] See attached Figure 4 An inner rotating tube 506 is rotatably installed inside the dismantling tube 502, and the side walls of the nut butt tube 503 close to the inner rotating tube 506 are both provided with pointed bevel teeth 507 in a circular array, and a spring 508 is provided between the nut butt tube 503 and the inner rotating tube 506, an inner extension rod 509 is fixedly connected to the inside of one end of the dismantling tube 502, and the inner extension rod 509 extends to the surface of the inner rotating tube 506 and a partition 1 510 is provided in a circular array, and the inner wall of the inner rotating tube 506 is provided with a partition 2 in a circular array, and the partition 1 510 and the partition 2 are arranged alternately and a curved spring is connected between the two.

[0034] The nut push tube 503 is then moved inwardly through the meshing of the tip bevel teeth 507 and the tip bevel teeth 507, so that the nut push tube 503 can be connected to the inner rotating tube 506. During the meshing of the tip bevel teeth 507 on both sides, the inner rotating tube 506 can simultaneously rotate relative to the inner extension rod 509. At this time, the corresponding partition 1 510 and partition 2 will approach and squeeze the curved spring at the same time. Finally, the motor 501 is started. The motor 501 will finally drive the nut push tube 503 to rotate, so that the nut can be removed by rotating the nut push tube 503. The removed nut will remain in the hexagonal groove 504 under the adsorption of the magnet 505, which is convenient for the subsequent mold to be reinstalled. This nut removal mechanism 5 specially designed for removing nuts can facilitate the removal of nuts at different installation angles, and can ensure that nuts at different installation angles can finally be embedded in the hexagonal groove 504, thereby facilitating the rapid rotation and removal of the nuts.

[0035] The working principle of the utility model is as follows: when disassembling a mold, the demoulding top casing 1 is controlled to move downward by the lifting mechanism, at which time one side of the mold will fit with the mold abutment plate 2, and then the cylinder 103 is started to shrink, at which time the slider 1 301 will move along the main guide rail 101, and the main dismantling frame 3 will drive the nut removal mechanisms 5 at both ends of the bottom to move toward the mold; while the slider 1 301 moves, the support rod 302 will move along with it, and under the connection of the transmission rotating arm 104, the sliding sleeve 303 will move toward the slider 1 301 along the support rod 302 at the same time, because the top rod 1 304 at the top of the slider 1 301 is inserted into the middle straight groove 107, the driving rotating arm 105 will be driven to rotate at the same time, and because the top rod 2 402 at the top of the slider 2 401 is inserted into the end straight groove 106, while the driving rotating arm 105 rotates, the slider 2 401 will be driven to move along the side guide rail 102, and finally, the side dismantling frame 4 will simultaneously drive the nut removal mechanisms 5 at both ends of its bottom to move toward the mold;

[0036] According to the position of the nut on the outer wall of the mold, the position of the corresponding nut removal mechanism 5 can be changed by adjusting the telescopic position between the inner insert frame 306 and the pipe frame 305, and finally the inner insert frame 306 is fixed with the fixing screw 307;

[0037] When the nut is removed by the nut removal mechanism 5, the nut will enter the hexagonal groove 504, and the nut push tube 503 will move inward, and then the tip bevel gear 507 will mesh with the tip bevel gear 507, so that the nut push tube 503 can be connected with the inner rotating tube 506. During the meshing of the tip bevel gears 507 on both sides, the inner rotating tube 506 will rotate relative to the inner extension rod 509 at the same time. At this time, the corresponding partition 1 510 and partition 2 will approach and squeeze the curved spring at the same time. Finally, the motor 501 is started. The operation of the motor 501 will drive the removal tube 502 to rotate, and the removal tube 502 will drive the inner rotating tube 506 to rotate. Because the nut push tube 503 and the inner rotating tube 506 are connected due to the meshing of the tip bevel gear 507, the nut push tube 503 will be driven to rotate at last, and then the nut will be removed by the rotation of the nut push tube 503. The removed nut will remain in the hexagonal groove 504 under the adsorption of the magnet 505, which is convenient for the subsequent reinstallation of the mold.

[0038] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the technical field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention.
