[0023] In this embodiment, two sets of transmission mechanisms are arranged on the back sides of the bracket 1 to provide power for the lifting of the lifting platform. In order to further improve the stability of the lifting platform in lifting the template, the lifting platform is lifted in a unidirectional and step-by-step manner under the action of the step-by-step lifting assembly, thereby ensuring the safety of the lifting platform in transporting the template.

[0024] Furthermore, the lifting platform includes two through slots 2, which are respectively opened on opposite sides of the bracket 1, and a mounting block 3 slidably installed inside each through slot 2 and can slide longitudinally.

Therefore, when the mounting block 3 is lifted, the template on the placing plate 6 can be lifted to a suitable position, and then the mold closing and demolding process of the template is further completed through the telescopic operation of the hydraulic telescopic rod 5. It is worth noting that the step-by-step lifting component here is used to control the step-by-step locking process of the corresponding mounting block 3, and the transmission mechanism drives the lifting and lowering operation of the corresponding mounting block 3.

[0026] Furthermore, each transmission mechanism includes a transmission groove 7 opened on the outer wall of the bracket 1, and the transmission groove 7 is connected to the through groove 2; and a transmission plate 8 slidably installed inside the transmission groove 7, and the transmission plate 8 is fixedly connected to the corresponding side mounting block 3 through a connecting block; and also includes a pull rope transmission assembly arranged on the outer wall of the bracket 1, and the pull rope transmission assembly is used to drive the transmission plate 8 to move longitudinally.

[0027] Here, the transmission groove 7 is connected with the through groove 2.

Therefore, when the pull rope transmission assembly drives the transmission plate 8 to move longitudinally, it can drive the mounting block 3 to move up and down, thereby realizing the lifting and lowering process of the template.

[0028] Furthermore, the rope transmission assembly includes a third transmission wheel 13 and a fourth transmission wheel 12, and the third transmission wheel 13 and the fourth transmission wheel 12 are rotatably connected to the upper and lower parts of the transmission plate 8 respectively; and a first drive wheel 25, a first transmission wheel 9, a second transmission wheel 10, and a second drive wheel 26 which are rotatably connected at the corners of the bracket 1 in sequence; it also includes a rope body 11 which is sequentially sleeved on the first drive wheel 25, the first transmission wheel 9, the third transmission wheel 13, the second transmission wheel 10, the second drive wheel 26, and the fourth transmission wheel 12 and connected end to end; a trigger assembly is also provided on the transmission plate 8, which is used to control the engagement and disengagement movement of the ratchet bar 20 and the ratchet block 17 where the step-by-step lifting assembly is located.

[0037] like Figure 3 , 7 As shown, when the transmission plate 8 is at a certain height, when the first drive wheel 25 and the second drive wheel 26 are running in the same direction, the third drive wheel 13 and the fourth drive wheel 12 on the transmission plate 8 rotate in the opposite direction of the first drive wheel 25 and the second drive wheel 26, so that the electric sheet on the mounting bar 14 contacts the electric column 15, and the first electric telescopic rod 18 is retracted by the single-chip microcomputer in the device to disengage the ratchet bar 20 from the ratchet block 17, and then the first drive wheel 25 and the second drive wheel 26 are driven to run in the opposite direction to complete the descending process of the transmission plate 8.
