[0024] In one embodiment, as shown in Figures 1-4, a precast template forming device includes a base 100 and an adjustable side mold 200. The adjustable side mold 200 is located on the upper end of the base 100, and a driving mechanism 300 for driving the adjustable side mold 200 to demold is provided at the lower end of the base 100. The adjustable side mold 200 is composed of four side plates 201 arranged on the base 100. Quick-release connectors 400 are provided at the connection between adjacent side plates 201. A lifting assembly 500 is also provided on the base 100. In use, the mold size can be adjusted by adjusting the adjustable side mold 200 as needed, and then concrete can be poured. When demolding, the connection between the side plates 201 is first released by the quick-release connectors 400, and then the driving mechanism 300 drives the side plates 201 to move outward at the same time. At the same time, the lifting assembly 500 lifts the precast component to achieve rapid demolding.

[0025] In one embodiment, as shown in FIG3, the base 100 includes a bottom template 101, a first partition 102 is provided at the lower end of the bottom template 101, a second partition 103 is provided at the lower end of the first partition 102, a support column 104 is provided at the lower end of the second partition 103, and a base plate 105 is provided at the lower end of the support column 104.

[0026] In one embodiment, as shown in FIG3, four through-type slide grooves 106 are symmetrically provided on the bottom template 101, and two guide grooves 107 are symmetrically provided on both sides of each slide groove 106. The bottom template 101 is provided with an installation groove 108 for installing the lifting component 500 in the middle. During demolding, the side plate 201 is driven to move outward along the slide grooves 106 and guide grooves 107 by the drive mechanism 300.

[0027] In one embodiment, as shown in Figure 4, the four side plates 201 are arranged in a rectangle. Each side plate 201 has a movable column 202 rotatably connected to its lower end. Two guide blocks 203 are symmetrically arranged on both sides of the movable column 202. The guide blocks 203 are slidably disposed within the guide groove 107. One end of each side plate 201 has a positioning block 204, and the other end has a positioning groove 205. Two oppositely arranged side plates 201 have a movable template 206 on one side.

The lower end of the movable column 202 extends through the slide groove 106 into the arc-shaped slide groove 302. When the side plate 201 is connected, the positioning block 204 and the positioning groove 205 are matched and aligned to avoid misalignment between the side plates 201. Then, according to the size of the precast component, the screw 207 is rotated to adjust the position of the movable template 206. When demolding, the movable column 202 is driven to move along the slide groove 106 by the drive mechanism 300, and at the same time, the guide block 203 moves along the guide groove 107.

[0028] In one embodiment, as shown in FIG3, the driving mechanism 300 includes a driving plate 301 and a driving assembly. The driving plate 301 is rotatably connected to the upper end of the first partition 102, and the driving assembly is located at the lower end of the first partition 102. Four arc-shaped slide grooves 302 are symmetrically provided on the driving plate 301. During demolding, the driving assembly drives the driving plate 301 to rotate, and the arc-shaped slide grooves 302 drive the movable column 202 to move along the slide groove 106.

[0029] In one embodiment, as shown in FIG3, the driving assembly includes a rotating shaft 303 passing through the first partition 102. The upper and lower ends of the rotating shaft 303 are rotatably connected to the bottom template 101 and the second partition 103, respectively. The rotating shaft 303 is fixedly connected to the driving plate 301. A worm gear 304 is provided on the rotating shaft 303. A worm 305 is meshed with one side of the worm gear 304. Both ends of the worm 305 are rotatably connected to the side wall of the bottom template 101. A stepper motor 306 is provided at one end of the worm 305. In use, the stepper motor 306 drives the worm 305 to rotate, and at the same time, the worm gear 304 drives the rotating shaft 303 and the driving plate 301 to rotate together.

[0030] In one embodiment, as shown in FIG4, the quick-release connector 400 includes a first fixing seat 401 fixed on the side plate 201, a rotating seat 402 rotatably connected to the first fixing seat 401, a connecting rod 403 on one side of the rotating seat 402, a second fixing seat 404 on one side of the connecting rod 403, the second fixing seat 404 fixed on the adjacent side plate 201, the second fixing seat 404 having a slot 405, and a fastening knob 406 threadedly connected to one end of the connecting rod 403. Before concrete pouring, the side plate 201 is closed, and then the connecting rod 403 is rotated to engage with the slot 405, and then the fastening knob 406 is rotated to fix the adjacent side plates 201 together.

[0031] In one embodiment, as shown in FIG5, the lifting assembly 500 includes a cylinder 501 disposed between the second partition plate 103 and the bottom plate 105. The output end of the cylinder 501 is provided with a push rod 502. The upper end of the push rod 502 passes through the entire base 100 and is connected to the top plate 503 installed in the mounting groove 108. The lower end of the top plate 503 is provided with a spring 504. When the cylinder 501 is not working, the top surface of the top plate 503 is flush with the top surface of the bottom template 101. During demolding, the cylinder 501 moves the push rod 502 upward, thereby driving the top plate 503 to lift the precast component. After the cylinder 501 is closed, the top plate 503 and the push rod 502 return to their initial positions by the action of the spring 504.

[0032] The above embodiment discloses a precast template forming device. In use, the four side plates 201 are first closed by the drive mechanism 300, then the connecting rod 403 is rotated to make it snap into the slot 405, and then the fastening knob 406 is rotated to fix the adjacent side plates 201. Next, according to the size of the precast component, the screw 207 is rotated to adjust the position of the movable template 206. Then, concrete is poured. When demolding, the locking of the quick-release connector 400 is first released, and the worm gear 305 is driven to rotate by the stepper motor 306. At the same time, the rotating shaft 303 and the drive plate 301 are driven to rotate together by the worm wheel 304. At the same time, the movable column 202 moves along the slide 106 through the arc-shaped slide 302, which moves the side plates 201 to the outside. At the same time, the top rod 502 is moved upward by the cylinder 501, which drives the top plate 503 to lift the precast component, thereby achieving rapid demolding.
