[0055] Embodiment 1

[0056] See also Figures 1 to 12 As shown, the present invention is a four-oil cylinder mold frame rotating device 100, the four-oil cylinder mold frame rotating device 100 comprises a mold frame body 1 and a rotating drive mechanism 2 arranged at both ends of the mold frame body 1, so that the rotating drive mechanism 2 at both ends cooperates to drive the mold frame body 1 to rotate;

[0057] Please refer to Figure 4-Figure 8 As shown, the rotary drive mechanism 2 includes a support housing 21, a first drive cylinder 22, a second drive cylinder 23, a third drive cylinder 24, a fourth drive cylinder 25, an output shaft 26, a first piston rack 27 and a second piston rack 28;

[0058] The first drive cylinder 22 and the second drive cylinder 23 are arranged on either side of the support shell 21, and the third drive cylinder 24 and the fourth drive cylinder 25 are arranged on the other side of the support shell 21; the central axes of the first drive cylinder 22 and the third drive cylinder 24 are located on the same straight line, the first piston rack 27 is arranged in the support shell 21, one end of the first piston rack 27 is movably connected to the first drive cylinder 22, and the other end of the first piston rack 27 is movably connected to the third drive cylinder 24, that is, the movable ends of the first drive cylinder 22 and the third drive cylinder 24 are arranged facing each other, and the first drive cylinder 22 and the third drive cylinder 24 are connected by the first piston rack 27, so that in specific operation, when the first drive cylinder 22 pushes the first piston rack 27 forward, the third drive cylinder 24 will correspondingly retract the first piston rack 27 inward, and vice versa, when the third drive cylinder When the first piston rack 27 is pushed forward by the second drive cylinder 24, the first drive cylinder 22 will correspondingly retract the first piston rack 27 inward; the central axes of the second drive cylinder 23 and the fourth drive cylinder 25 are located on the same straight line, one end of the second piston rack 28 is movably connected to the second drive cylinder 23, and the other end of the second piston rack 28 is movably connected to the fourth drive cylinder 25, that is, the movable ends of the second drive cylinder 23 and the fourth drive cylinder 25 are arranged facing each other, and the second drive cylinder 23 and the fourth drive cylinder 25 are connected through the second piston rack 28, so that in specific operation, when the second drive cylinder 23 pushes the second piston rack 28 forward, the fourth drive cylinder 25 will correspondingly retract the second piston rack 28 inward, and vice versa, when the fourth drive cylinder 25 pushes the second piston rack 28 forward, the second drive cylinder 23 will correspondingly retract the second piston rack 28 inward;

[0059] The output shaft body 26 is rotatably arranged in the support shell 21 and is located between the first piston rack 27 and the second piston rack 28. The output shaft body 26 is provided with driving teeth 261 around the circumferential direction. The first piston rack 27 and the second piston rack 28 are both engaged with the driving teeth 261 on the output shaft body 26, so that the first piston rack 27 and the second piston rack 28 can drive the output shaft body 26 to rotate when moving, wherein the movement directions of the first piston rack 27 and the second piston rack 28 are opposite; one end of the output shaft body 26 extends to the outside of the support shell 21 and is connected to the mold frame body 1, so that the output shaft body 26 is used to drive the mold frame body 1 to rotate.

[0060] When the four-cylinder mold frame rotating device 100 of the present invention is working, when the first driving cylinder 22 pushes the first piston rack 27 forward, it is necessary to make the fourth driving cylinder 25 push the second piston rack 28 forward synchronously, and at the same time, the third driving cylinder 24 will correspondingly retract the first piston rack 27 inward, and the second driving cylinder 23 will correspondingly retract the second piston rack 28 inward; on the contrary, when the third driving cylinder 24 pushes the first piston rack 27 forward, it is necessary to make the second driving cylinder 23 push the second piston rack 28 forward synchronously, and at the same time, the first driving cylinder 22 will correspondingly retract the first piston rack 27 inward. The fourth drive cylinder 25 will correspondingly retract the second piston rack 28 inward; because the first piston rack 27 and the second piston rack 28 are both engaged with the driving teeth 261 on the output shaft 26, they can well drive the output shaft 26 to rotate. Since the present invention is to rotate the mold frame body 1 180° to achieve demolding or material distribution, during the specific implementation, the first piston rack 27 and the second piston rack 28 can be designed to drive the mold frame body 1 to rotate exactly 180° within an active stroke. In this way, the reciprocating motion of the first piston rack 27 and the second piston rack 28 can drive the mold frame body 1 to rotate reciprocatingly.

[0061] Since the overall weight of the mold frame body 1 and the formed water grooves in the present invention is very heavy, when the mold frame body 1 and the formed water grooves are driven to rotate together, if the output shaft is unevenly stressed, it will be easy to cause shaking, swaying, shaft deformation, etc. To this end, the present invention cleverly designs and utilizes the method of mutual cooperation between four drive cylinders and two piston racks, and the four drive cylinders cooperate in pairs to drive the two piston racks to make linear motion; at the same time, an output shaft body 26 is provided between the two piston racks, and the output shaft body 26 is provided with drive teeth 261 meshing with the two piston racks around the circumferential direction, so as to realize the conversion of the linear motion of the two piston racks into rotational motion, thereby driving the mold frame body 1 to rotate; by adopting the above structural design of the present invention, on the one hand, because the output shaft body 26 is located between the two piston racks, the output shaft body 26 can effectively reduce the rotational motion of the two piston racks. Between the bars, the upper and lower piston racks will act on the output shaft 26 when working, so that the upper and lower sides of the output shaft 26 are symmetrically stressed, thereby reliably driving the mold frame body 1 and the formed water groove to rotate smoothly, ensuring that there will be no shaking, shaking, etc. in the process of rotation, and the output shaft 26 will not bend or deform due to uneven force, which is beneficial to improving the service life; on the other hand, it is only necessary to control the active stroke of the two piston racks to accurately control the required rotation angle of the mold frame body 1, which is simple to implement and can ensure the rotation accuracy.

[0062] As a specific implementation of the present invention, the first drive cylinder 22, the second drive cylinder 23, the third drive cylinder 24 and the fourth drive cylinder 25 are all hydraulic cylinders.

[0063] In some embodiments of the present invention, the rotary drive mechanism 2 further includes a bearing 29; the output shaft 26 is rotatably connected to the support housing 21 via the bearing 29, and the output shaft 26 is provided with the bearing 29 on both sides of the driving tooth 261. By providing the bearing 29 between the output shaft 26 and the support housing 21, the friction between the output shaft 26 and the support housing 21 can be effectively reduced, ensuring that the output shaft 26 can rotate smoothly and reliably.

[0064] Furthermore, the output shaft body 26 has a first shaft section 262 rotatably disposed in the support housing 21, a gear ring 20 with the driving teeth 261 is fixedly sleeved in the middle of the first shaft section 262, and bearing sleeve sections 2621 are formed at both ends of the first shaft section 262, and the inner ring of the bearing 29 is fixedly sleeved on the bearing sleeve section 2621 to achieve the installation of the bearing 29. In the embodiment of the present invention, the driving teeth 261 are formed by fixing the gear ring 20 in the middle of the first shaft section 262, but the present invention is not limited thereto, and the driving teeth 261 can also be directly formed in the middle of the first shaft section 262 in a specific implementation.

[0065] In some embodiments of the present invention, a first sealing cover 211 is provided on the outside of the support shell 21 at a position corresponding to each of the bearings 29. The first sealing cover 211 is detachably connected to the support shell 21. In a specific implementation, the first sealing cover 211 and the support shell 21 can be locked together by screws or bolts.

[0066] The present invention provides a removable first sealing cover 211 at a position corresponding to the bearing 29 on the outside of the support shell 21. On the one hand, the first sealing cover 211 can be opened during installation, repair, and maintenance, thereby facilitating actual installation, repair, and maintenance operations; on the other hand, the first sealing cover 211 can be sealed during normal use to ensure that external dust and the like will not enter the interior of the support shell 21.

[0067] In some embodiments of the present invention, the first piston rack 27 and the second piston rack 28 are each provided with a limit block 3 on the side opposite to the teeth, and the limit block 3 is adjacent to the side opposite to the teeth of the first piston rack 27 and the second piston rack 28, and a second sealing cover 212 is provided on the outside of the support shell 21 at a position corresponding to each limit block 3, and the second sealing cover 212 is detachably connected to the support shell 21, and specifically, the second sealing cover 212 and the support shell 21 can be locked together by screws or bolts, and the limit block 3 is connected to the second sealing cover 212. Since the toothed side of the first piston rack 27 and the second piston rack 28 are meshed with the driving teeth 261 of the output shaft body 26, by arranging the limit blocks 3 on the side of the first piston rack 27 and the second piston rack 28 facing away from the teeth, the first piston rack 27 and the second piston rack 28 can be well limited to ensure that the first piston rack 27 and the second piston rack 28 will not be separated from the driving teeth 261 of the output shaft body 26, thereby ensuring the stability of use; at the same time, the second sealing cover 212 can not only support the limit blocks 3, but also prevent external dust and the like from entering the support shell 21.

[0068] In some embodiments of the present invention, support members 11 are provided at both ends of the mold body 1, and a vibration-damping structure 4 is provided between the support members 11 and the mold body 1; because the mold body 1 needs to use a vibration mechanism 5 (such as a vibration motor) to vibrate the mold body 1 when the water groove is specifically formed, the vibration mechanism 5 is arranged at the bottom of the mold body 1 to ensure the quality of the formed water groove; and in the process of the vibration mechanism vibrating the mold body 1, since the rotating drive mechanism 2 is connected to the mold body 1, the vibration force generated by the vibration mechanism 5 will inevitably be transmitted to the rotating drive mechanism 2, which will have an adverse effect on the rotating drive mechanism 2; for this reason, the present invention adopts a vibration-damping structure 4 provided between the support member 11 and the mold body 1, so that in specific operation, the vibration-damping structure 4 can be used to reduce the vibration force generated by the vibration mechanism 5, so as to effectively reduce the impact on the rotating drive mechanism 2.

[0069] Please refer to Fig. 9 As shown, a shaft sleeve 12 is fixedly provided in the middle of the support member 11, and a first key groove 121 is formed on the inner wall of the shaft sleeve 12, and the first key groove 121 extends to both ends of the shaft sleeve 12; the output shaft 26 also has a second shaft section 263 extending to the outside of the support shell 21, and the second shaft section 263 is provided with a second key groove 2631 matching the first key groove 121, and the second shaft section 263 and the shaft sleeve 11 are assembled together by a key.

[0070] The present invention arranges a shaft sleeve 12 in the middle of the support member 11, forms a first keyway 121 on the inner wall of the shaft sleeve 12, and designs the output shaft 26 to have a second shaft section 263, and a second keyway 2631 is arranged on the second shaft section 263, so that during the specific assembly, a key connection method can be used to assemble the output shaft 26 and the support member 11 together, and the assembly operation is simple and the reliability is good.

[0071] Furthermore, in order to achieve a better vibration reduction effect, the vibration reduction structure 4 includes an assembly part 41, a vibration reduction block 42 and a locking part 43;

[0072] The assembly part 41 is fixedly arranged on the end face of the mold frame body 1, and the support member 11 is provided with a horizontal support plate 111 on the side facing the mold frame body 1, and the top and bottom of the horizontal support plate 111 are provided with vibration-damping blocks 42. In the specific implementation of the present invention, the top and bottom of the horizontal support plate 111 are provided with vibration-damping blocks 42 on both sides of the shaft sleeve 12, and the vibration-damping blocks 42 can be made of elastic material blocks such as rubber blocks; the vibration-damping blocks 42, the horizontal support plate 111 and the assembly part 41 are locked together by the locking member 43, wherein the locking member 43 can include bolts and nuts.

[0073] The present invention can effectively reduce vibration by arranging vibration-damping blocks 42 at the top and bottom of the horizontal support plate 111, and assembling and connecting the vibration-damping blocks 42, the horizontal support plate 111 and the assembly parts 41 together using locking parts 43, thereby ensuring that the vibration force generated by the vibration mechanism 5 has almost no effect on the rotating drive mechanism 2.

[0074] In some embodiments of the present invention, please refer to Figure 10-12 As shown, the four-cylinder mold frame rotating device 100 also includes a hook plate mechanism 6, and the two ends of the mold frame body 1 are provided with the hook plate mechanism 6; because in specific use, after the water groove in the mold frame body 1 is formed, before the mold frame body 1 and the formed water groove are rotated, it is necessary to place a support plate 200 on the top of the mold frame body 1, so as to use the support plate 200 to support the formed water groove to ensure that the water groove will not fall, and it is also convenient to use the support plate 200 to send out the demoulding water groove; therefore, in order to ensure that the support plate 200 will not fall during the rotation process, the present invention adopts the use of hook plate mechanisms 6 at both ends of the mold frame body 1, so as to use the hook plate mechanism 6 to hook the support plate 200 placed on the mold frame body 1 tightly;

[0075] The hook plate mechanism 6 includes a telescopic assembly 61 and a connecting rod assembly 62. The telescopic assembly 61 is installed at the end of the mold frame body 1. Specifically, the telescopic assembly 61 can be installed on the assembly part 41. The connecting rod assembly 62 is connected to the telescopic end of the telescopic assembly 61. The free end of the connecting rod assembly 62 is formed with a hook portion 621. The telescopic assembly 61 drives the connecting rod assembly 62 to link the hook portion 621 to hook or loosen the pallet 200 placed on the mold frame body 1. Specifically, after the pallet 200 is placed on the mold frame body 1, the telescopic assembly 61 drives the connecting rod assembly 62 to link the hook portion 621 to hook the pallet 200 on the mold frame body 1; and after the mold frame body 1 and the formed water groove are rotated 180° and the pallet 200 is supported, the telescopic assembly 61 drives the connecting rod assembly 62 to link the hook portion 621 to loosen the pallet 200.

[0082] The rotation method comprises:

[0083] The first driving cylinder 22 is controlled to push the first piston rack 27 forward by a preset length, and the fourth driving cylinder 25 is controlled to synchronously push the second piston rack 28 forward by a preset length. The movement directions of the first piston rack 27 and the second piston rack 28 are opposite to each other, so as to ensure that the output shaft 26 can be driven to rotate under the action of the first piston rack 27 and the second piston rack 28. During this process, the third driving cylinder 24 correspondingly retracts the first piston rack 27 inward by a preset length, and the second driving cylinder 23 correspondingly retracts the second piston rack 28 inward by a preset length. At the same time, the first piston rack 27 and the second piston rack 28 drive the output shaft 26 to rotate 180° in the forward direction through the meshing driving teeth 261, thereby driving the mold frame body 1 to rotate 180° in the forward direction;

[0084] The third driving cylinder 24 is controlled to push the first piston rack 27 forward by a preset length, and the second driving cylinder 23 is controlled to synchronously push the second piston rack 28 forward by a preset length. The movement directions of the first piston rack 27 and the second piston rack 28 are opposite to each other, so as to ensure that the output shaft 26 can be driven to rotate under the action of the first piston rack 27 and the second piston rack 28. During this process, the first driving cylinder 22 correspondingly retracts the first piston rack 27 inward by a preset length, and the fourth driving cylinder 25 correspondingly retracts the second piston rack 28 inward by a preset length. At the same time, the first piston rack 27 and the second piston rack 28 drive the output shaft 26 to rotate 180° in the opposite direction through the meshing driving teeth 261, thereby driving the mold frame body 1 to rotate 180° in the opposite direction.

[0085] In a specific implementation of the present invention, after the mold frame body 1 has formed the water groove, the mold frame body 1 and the formed water groove can be driven by the rotary drive mechanism 2 to rotate forward 180° together, and in order to support the formed water groove and prevent the support plate 200 from falling off, the rotation method also includes: after the mold frame body 1 has formed the water groove, the support plate 200 is placed on the top of the mold frame body 1, and the hook plate mechanism 6 is controlled to hook the support plate 200; at the same time, after the rotary drive mechanism 2 drives the mold frame body 1 and the formed water groove to rotate forward 180° together, and the support plate 200 is supported, the hook plate mechanism 6 is controlled to release the support plate 200. At the same time, after the mold frame body 1 completes the demoulding of the water groove, the mold frame body 1 and the formed water groove are driven by the rotary drive mechanism 2 to rotate backward 180° together, thereby driving the mold frame body 1 to return to its position, so as to continue the fabrication and molding.

[0086] Although the specific implementation modes of the present invention are described above, those skilled in the art should understand that the specific implementation modes described are only illustrative and are not intended to limit the scope of the present invention. Equivalent modifications and changes made by those skilled in the art in accordance with the spirit of the present invention should be included in the scope of protection of the claims of the present invention.
