DETAILED DESCRIPTION OF THE EMBODIMENTS

[0016] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0017] Please refer to Figures 1-3 , a forming device for autoclaved aerated concrete blocks in this embodiment includes a conveyor 1. A bracket 2 is fixedly installed at the left end of the outside of the conveyor 1. Two vertical rods 4 are fixedly installed on the front and back of the bracket 2. A forming mechanism is arranged inside the bracket 2, and a leveling mechanism is arranged inside the forming mechanism. A pallet 21 with one end in contact with the forming mechanism is placed on the top of the conveyor 1;

[0018] In this embodiment, the forming mechanism includes a demolding cylinder 5, a bearing platform 7, and an adjusting cylinder 9. The demolding cylinder 5 is fixedly installed on the top of the bracket 2. The demolding cylinder 5 penetrates and extends into the inside of the bracket 2. The output end of the demolding cylinder 5 is fixedly installed with a movable seat 20. A pressing plate 6 is detachably installed at the bottom of the movable seat 20. The movable seat 20 is slidably installed on the outside of the whole vertical rod 4. There are two adjusting cylinders 9, and the adjusting cylinders 9 are respectively fixedly installed on the front and back of the bracket 2. The output end of the whole adjusting cylinder 9 is fixedly connected with the bearing platform 7. The bearing platform 7 is slidably installed on the outside of the whole vertical rod 4. A prefabricated mold 10 is fixedly installed inside the bearing platform 7. Vibration motors 11 are fixedly installed at both the front and back ends of the top of the bearing platform 7. A guiding groove 3 is fixedly installed on the left side of the prefabricated mold 10. Buffer springs 8 are arranged at the four corners of the top of the movable seat 20 and the four corners of the bottom of the bearing platform 7. The buffer springs 8 are sleeved on the outside of the vertical rod 4 and are fixedly connected with the bracket 2. The pallet 21 is in contact with the bottom of the prefabricated mold 10. The upper and lower buffer springs 8 as a whole are respectively in contact with the movable seat 20 and the bearing platform 7. The guiding groove 3 penetrates and extends into the inside of the prefabricated mold 10.

[0019] It should be noted that the lower buffer spring 8 as a whole effectively buffers the force of the operation of the vibration motor 11 to ensure the overall safety of the device during use and extend the overall service life of the device; the upper buffer spring 8 as a whole plays a buffering role after the movable seat 20 is reset.

[0020] Specifically, a quantitative amount of cement slurry is guided into the interior of the precast mold 10 through the guiding groove 3. Then, the vibration motor 11 is started to cause the bearing platform 7 to oscillate, driving the precast mold 10 to oscillate, so that the cement slurry inside the precast mold 10 is evenly distributed. Then, the leveling mechanism is started to level the top of the block formed by the cement slurry. At this time, the leveling mechanism resets. The demolding cylinder 5 is started to drive the pressing plate 6 to move downward through the movable seat 20 to contact the top of the formed block. The adjusting cylinder 9 is started to drive the bearing platform 7 to move the precast mold 10 upward, so that the formed block is completely demolded onto the top of the pallet 21 and transported to the next process on the right side through the conveyor 1. Before the forming mechanism operates again, another pallet 21 is transported under the precast mold 10 through the conveyor 1, and the block forming can be carried out again to enable continuous operation.

[0021] In this embodiment, the leveling mechanism includes L-shaped support plates 12 and a reduction motor 14. The number of L-shaped support plates 12 is four. The L-shaped support plates 12 are evenly and fixedly installed at the front and rear ends of the top of the bearing platform 7. An adjusting screw 13 is rotatably installed between the L-shaped support plates 12. The adjusting screw 13 penetrates and extends to the right side of the right L-shaped support plate 12. The precast mold 10 is located between the left and right L-shaped support plates 12 as a whole. A reduction motor 14 is fixedly installed on the top of the bearing platform 7. The output end of the reduction motor 14 is fixedly connected to the left side of the front adjusting screw 13. An adjusting nut 15 is threadedly installed on the outside of the adjusting screw 13. A U-shaped positioning plate 16 is fixedly installed between the adjusting nuts 15. The U-shaped positioning plate 16 is slidably installed on the outside of the precast mold 10. A leveling plate 17 is detachably installed between the U-shaped positioning plates 16. A linkage sprocket 18 is fixedly installed on the outside of the adjusting screw 13. A transmission chain 19 is installed on the outside of the whole linkage sprocket 18 in a driving manner.

[0022] It should be noted that the leveling plate 17 is at the same horizontal plane as the top of the block inside the precast mold 10.

[0023] Specifically, after the cement inside the precast mold 10 oscillates evenly, the reduction motor 14 is started to drive the front adjusting screw 13 to rotate. Then, the front and rear two linkage sprockets 18 are driven to rotate through the transmission chain 19, so that the rear adjusting screw 13 rotates, thereby driving the adjusting nut 15 to move to the right under the restriction of the U-shaped positioning plate 16 to level the top of the block inside the precast mold 10.
