A locking member 22 for preventing the mold from separating is installed on one side of the forming mold. A lifting mechanism 3 for unlocking the locking member 22 is fixedly installed on one side of the machine body 1, and an opening mechanism 4 for pushing the locking member 22 to drive the forming mold to complete the opening work is fixedly installed on the inner side of the machine body 1.

[0037] When in use, first, the forming module 21 is conveyed to one side of the machine body 1 through the conveying platform 2; then, the locking piece 22 of the forming module 21 is unlocked by using the lifting mechanism 3; then, the opening mechanism 4 is started to push one end of the locking piece 22 until the forming module 21 is in a fully opened state, and the opening work of the insole forming mold is completed, so that the worker can take out the insole inside the mold.

[0038] refer to Figure 1 , Figure 2The molding module 21 includes an upper mold 212 and a lower mold 211, and the upper mold 212 is hinged to one end of the lower mold 211. The lower side of the lower mold 211 is fixedly connected to the upper side of the working plate on the upper side of the conveyor 2, and one end of the working plate is fixedly connected to a baffle with a limit on the opening angle of the upper mold 212, which is used to prevent the opening angle of the upper mold 212 from being too large, so as to facilitate the subsequent mold closing. When in use, the insole raw material is injected into the lower mold 211, and then the upper mold 212 is covered on the upper side of the lower mold 211, and the raw material can be squeezed into the style of the insole. Finally, the upper mold 212 is opened and the formed insole is taken out, and the preliminary production of the insole is completed.

[0039] refer to Figure 1 , Figure 2 The locking member 22 includes two locking blocks fixedly connected to the upper mold 212 and the lower mold 211 respectively, and the two locking blocks are fitted and connected to each other when the upper mold 212 and the lower mold are closed. A rotating rod rotatably connected to the locking block is provided on one side of the upper mold 212, and a limiting rod 221 for limiting the rotation angle of the rotating rod is fixedly connected to the side of the rotating rod close to the upper mold 212. A locking plate for pressing against the locking block on one side of the lower mold 211 is fixedly connected to the side of the rotating rod away from the limiting rod 221. The locking plate is used to fix the two locking blocks together to prevent the upper mold 212 and the lower mold 211 from separating when closing the mold. A gripping rod 222 for pushing the locking plate against one side of the locking block or separating the locking plate from the locking block is fixedly connected to the side of the rotating rod connected to the locking plate.

[0040] When the upper mold 212 and the lower mold 211 are closed, the gripping rod 222 is pulled downward to press the locking plate against the outer side of the lower locking block, thereby completing the locking work of the upper mold 212 and the lower mold 211; the gripping rod 222 is pulled upward to push the rotating rod to rotate, thereby driving the locking plate to separate from the locking seat on the lower side until the limiting rod 221 is in contact with one side of the upper mold 212, thereby completing the unlocking work of the upper mold 212 and the lower mold 211, thereby facilitating the opening operation.

[0041] refer to Figure 3 , Figure 4 The lifting mechanism 3 includes a driving cylinder 31 fixedly connected to the body 1 and a lifting plate 32 fixedly connected to the upper end of the piston rod of the driving cylinder 31. The driving cylinder 31 is used to push the lifting plate 32 to move up and down until the upper side of the lifting plate 32 contacts the gripping rod 222, so that the locking member 22 can be unlocked. A limit frame 33 fixedly connected to the body 1 and sleeved on the outside of the piston rod of the driving cylinder 31 is provided on the lower side of the lifting plate 32. The limit frame 33 is used to limit the movement range of the lifting plate 32, thereby improving the stability of the structure. A first gasket 321 is fixedly connected to the upper surface of the lifting plate 32 and is used to reduce the collision between the lifting plate 32 and the gripping rod 222.

[0042] When the conveying platform 2 conveys the forming module 21 to one side of the lifting mechanism 3, the lifting plate 32 is pushed up by driving the piston rod of the cylinder 31 until the first gasket 321 on the upper side of the lifting plate 32 contacts the gripping rod 222, driving one end of the gripping rod 222 to rotate upward, so that the lower end of the locking plate can be separated from the locking block on the lower side, thereby completing the unlocking work of the locking member 22.

[0043] refer to Figure 5 , Figure 6 and Figure 7 The cover opening mechanism 4 includes two driving motors 41 fixedly connected to the two ends of the machine body 1, and one end of the output shaft of the two driving motors 41 is fixedly connected to two transmission rods 42 that are rotatably connected to the inner wall of the machine body 1, and the outer wall of each transmission rod 42 is fixedly connected to two transmission wheels 43. A transmission belt 44 is rotatably sleeved between the transmission wheels 43 on the outer sides of the two transmission rods 42. The two transmission belts 44 rotate on the inner side of the machine body 1 through the two transmission wheels 43, and the inner wall of the machine body 1 is fixedly connected to an arc rod 8 for guiding the rotation of the transmission belt 44, and the arc rod 8 is used to ensure the stability of the rotation of the transmission belt 44. The opposite side of the two transmission belts 44 is fixedly connected to a connecting piece 441, and a movable plate 45 is fixedly connected between the two connecting pieces 441. An open groove 5 for the movable plate 45 to slide is opened on one side of the machine body 1.

[0044] When the transmission belt 44 rotates, it drives the movable plate 45 to slide on the inner wall of the opening groove 5, and the movable plate 45 further pushes the gripping rod 222 to move, thereby driving the upper mold 212 to complete the cover opening action.

[0045] refer to Figure 5 , Figure 6 and Figure 7 , shock-absorbing pads 7 for buffering the movable plate 45 are provided at both ends of the opening slot 5, one side of one of the shock-absorbing pads 7 is fixedly connected to a positioning block 6 fixedly connected to the machine body 1, and the other shock-absorbing pad 7 is fixedly connected to the inner wall of the lower end of the machine body 1, and the shock-absorbing pad 7 is used to reduce the collision between the movable plate 45 and the machine body 1 when it moves to the two ends of the opening slot 5. Two arc-shaped slide rails 9 are fixedly connected to the inner wall of the machine body 1, and the movable plate 45 is provided with a limiting groove 452 that is slidably connected to the outside of the arc-shaped slide rail 9, and the limiting groove 452 is used for the movable plate 45 to stably slide on the outside of the arc-shaped slide rail 9. A second gasket 451 is fixedly connected to one side of the movable plate 45, and the second gasket 451 is used to reduce the contact friction between the movable plate 45 and the handle 222.

[0046] When the transmission belt 44 rotates, it will drive the movable plate 45 to slide on the inner wall of the opening groove 5 until the second gasket 451 contacts the gripping rod 222; then, the transmission belt 44 continues to rotate, pushing the gripping rod 222 so that the upper mold 212 and the lower mold 211 are in an open and closed state, until the movable plate 45 contacts the upper shock-absorbing pad 7, and the rotating belt stops rotating, and the mold can be opened; finally, the rotating belt rotates in the opposite direction, driving the movable plate 45 back to its original position and fitting with the lower shock-absorbing pad 7, so that the next molding module 21 can be opened.

[0047] The implementation principle of the insole forming mold cover opening device of the embodiment of the present application is as follows: when in use, first, the forming module 21 is conveyed to the inner side of the machine body 1 through the conveying platform 2. When the forming module 21 passes through the lifting mechanism 3, the conveying platform 2 stops running, and the driving cylinder 31 is started to push the lifting plate 32 up, until the lifting plate 32 pushes the gripping rod 222 to rotate upward, so that the locking member 22 is in an unlocked state; then, the conveying platform 2 continues to operate to convey the forming module 21 to one side of the cover opening mechanism 4; then, one of the driving motors 41 is started to drive the transmission rod 42 and the transmission wheel 43 to rotate, so that the transmission belt 4 4 rotates on the inner wall of the body 1, thereby driving the movable plate 45 to slide along the arc-shaped slide rail 9 on the inner wall of the opening groove 5, so that one side of the movable plate 45 contacts the gripping rod 222, and then drives one end of the upper mold 212 to tilt up; with the continuous operation of the driving motor 41, until the movable plate 45 drives the upper mold 212 to complete the cover opening, the driving motor 41 stops running; at this time, another driving motor 41 is started to run in the reverse direction, driving the transmission rod 42, the transmission wheel 43 and the transmission belt 44 to rotate in the reverse direction, thereby driving the movable plate 45 back to the original position, and the cover opening process can be performed on the next molding mold again.

[0048] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
