[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0021] like Figures 1 to 5 As shown, the floor door frame back panel forming equipment of the present invention includes an upper mold assembly 1 and a lower mold assembly 2. The upper mold assembly 1 is arranged at the upper end of the lower mold assembly 2. The upper mold assembly 1 is equipped with a cylinder 3, a pressure block 4, a mounting plate 5, and a forming block 6, while the lower mold assembly 2 is equipped with a support plate 7 and a back panel 8.

[0022] A pressure block 4 is mounted at the lower end of the cylinder 3. A mounting plate 5 is also provided at the lower end of the pressure block 4. A forming block 6 is also provided at the lower end of the mounting plate 5. A movable member 9 is also provided at the lower end of the mounting plate 5. The movable member 9 is mounted to the lower end of the mounting plate 5 via a movable assembly 10. The cylinder 3 pushes the pressure block 4 downward, causing the mounting plate 5 and forming block 6 at the lower end to move downward together. The movable member 9 can adjust the size of the punched slots 11 on both sides of the back panel 8, where the buttons are placed, according to actual needs. Because buildings of varying heights require different numbers of buttons, the size of the button slots 12 must be adjusted accordingly.

[0023] The support plate 7 is provided with a receiving area 13 for receiving the back plate 8 and a stamping groove 11 cooperating with the forming block 6 and the moving part 9. The stamping groove 11 includes a key groove 12 and a door opening groove 14. The door opening groove 14 is used for entering and exiting the elevator and closing the floor door.

[0024] The movable assembly 10 is provided with an adjusting member 15 and a fastening bolt 16. A sunken groove 17 is provided in the middle of the movable member 9. The adjusting member 15 is placed in the sunken groove 17. The fastening bolt 16 is provided with a threaded portion 18. A threaded hole 19 is provided in the middle of the sunken groove 17 to cooperate with the threaded portion 18. The adjusting member 15 is provided with a first tooth 20, and the mounting plate 5 is provided with a strip hole 21. The length of the strip hole 21 is greater than the length of the adjusting member 15, so that the adjusting member 15 can be moved out from above the stamping grooves 11 on both sides. Second teeth 22 that cooperate with the first teeth 20 are provided around the strip hole 21. The first teeth 20 and the second teeth 22 cooperate to limit the position of the adjusting member 15.

[0025] The adjusting member 15 is composed of a moving block 23 and a sliding block 24. The first tooth 20 is arranged on the sliding block 24, and the sliding block 24 is arranged in the sinking groove 17. The depth of the sinking groove 17 is greater than the thickness of the sliding block 24.

[0026] A strip block 25 and a stop block 26 are provided on either side of the movable block 23. Receiving openings 27 are formed on either side of the strip block 25, and a V-shaped opening 28 is formed between the strip block 25 and the stop block 26. A V-shaped member 29 is positioned within the V-shaped opening 28. The V-shaped member 29 has a certain degree of elasticity. Both ends of the V-shaped member 29 maintain contact with the mounting plate 5. The V-shaped member 29 is mounted between the stop block 26 and the strip block 25 using bolts 30.

[0027] When installing the adjusting member 15, first install the V-shaped member 29 on the moving block 23, and then insert it from the lower end of the mounting plate 5 so that the strip hole 21 restricts the V-shaped member 29 and keeps both ends of the V-shaped member 29 entering the accommodating opening 27, thereby driving the V-shaped member 29 through the strip hole 21, and then keeping the V-shaped member 29 in contact with the upper end surface of the mounting plate 5.

[0028] When the fastening bolt 16 is rotated, the adjusting member 15 is pushed downward, causing the V-shaped member 29 to be squeezed and the angle between them to increase, thereby causing the sliding block 24 to move downward in the sinking groove 17, keeping the first tooth 20 and the second tooth 22 disengaged, so that the adjusting member 15 can be moved so that the adjusting member 15 is no longer above the stamping grooves 11 on both sides. Then, the support block that cooperates with the moving member 9 is placed in the stamping groove 11 to support the back plate 8.

[0029] In addition, the number of movable components 10 and movable parts 9 can be increased according to actual conditions to match the actual length of the key slot 12. When adjusting, they do not need to be removed, but only need to be moved along with the mounting plate 5. No additional storage is required, which speeds up the adjustment time and improves industrial output to a certain extent.

[0030] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
