[0017] The present invention will be further described in detail below with reference to the drawings and embodiments: As Figure 1-8 shown, a rotary multi-station foaming device includes a turntable 1, a plurality of molds 2, a plurality of brackets 3, and a plurality of conveying racks 4. The molds 2 are detachably connected to the brackets 3. The plurality of brackets 3 are arranged in an annular and equidistant manner at the top of the turntable 1. The top of the turntable 1 is connected with a plurality of limiting blocks 14 that cooperate with the brackets 3. The bottom of the bracket 3 is clamped with the limiting block 14. An annular groove 9 is opened at the outer end of the turntable 1. The bottom end of the inner wall of the annular groove 9 is connected with an annular slide rail 10. The annular slide rail 10 and the turntable 1 are coaxially arranged. The mold 2 abuts against the outer end of the turntable 1, and a slider 5 is connected to the inner end of the mold 2. The slider 5 is slidably connected with the annular slide rail 10. The top of the conveying rack 4 is inclined.

[0018] The rotary multi-station foaming device is a foaming molding device that adopts a rotating turntable structure to achieve multi-station cyclic operation. This device usually includes multiple independent stations and can simultaneously perform multiple processes such as feeding, foaming, curing, and demolding within the same production cycle, thereby improving production efficiency. Through the automatic rotation of the turntable, the stations sequentially enter different processing stages, eliminating the need for manual handling of molds or machine stoppage waiting, greatly optimizing the production process. There are multiple molds on the multi-station foaming device. The molds are usually installed on special brackets, and the brackets are usually welded to the turntable. During actual use, there is a requirement to replace some or all of the molds. Since the brackets are fixed to the turntable and there is a height difference between the turntable and the ground, it is extremely inconvenient to disassemble, replace, and install the molds, and a lifting device is required, which affects production continuity and increases the corresponding labor force.

[0019] In this solution, the bracket 3 and the turntable 1 are designed separately. The bracket 3 is clamped on the surface of the turntable 1 through the limit block 14, preventing it from displacing. The bottom of the bracket 3 can be inserted into the limit block 14 from the outside of the turntable 1. Since the mold 2 and the bracket 3 itself have a large mass and the rotation speed of the turntable 1 is slow, there is no need to consider that the rotation of the turntable 1 will throw the bracket 3 out. When replacing the mold, the user can install the bracket 3 to be replaced on the mold 2 in advance on-site, then stop the rotation of the turntable 1, and push the conveying frame 4 to move outside the turntable 1. The conveying frame 4 slides on the annular slide rail 10 through the slider 5 and moves along the outer end of the turntable 1. The user pushes the conveying frame 4 to one side of the bracket 3 and the mold 2 to be replaced, and then can push the bracket 3 on the turntable 1 out of the limit block 14 manually and push it down through the inclined surface of the conveying frame 4 to make it land smoothly. Then, push the mold 2 and the bracket 3 to be replaced along the conveying frame 4 onto the turntable 1 until the bottom of the bracket 3 is fully clamped with the limit block 14, and the replacement of the mold 2 can be realized. This replacement process is fast, does not require separate disassembly of the mold 2, does not require the aid of lifting equipment, saves manpower, and improves the production safety to a certain extent.

[0020] In this solution, the number of the conveying frames 4 can be set to two. While ensuring that it can meet the needs of replacing multiple molds simultaneously, it avoids too many conveying frames 4 occupying too much space and causing congestion in the production site.

[0021] The highest point of the inclined surface of the conveying frame 4 is flush with the surface of the turntable 1.

[0022] In this solution, the highest point of the inclined surface of the conveying frame 4 is flush with the surface of the turntable 1, enabling the bracket 3 to transition smoothly between the turntable 1 and the conveying frame 4, avoiding excessive jolts during the movement, and also avoiding the need for the user to lift the bracket 3 multiple times during the process, reducing the work difficulty, and also playing a certain protective role for the bracket 3.

[0023] A positioning block 6 for cooperating with the bracket 3 is connected to the inclined surface of the conveying frame 4.

[0024] In this solution, when the user pushes the bracket 3 onto the conveying frame 4, the bottom of the bracket 3 can be clamped with the positioning block 6 on the conveying frame 4, thereby limiting the moving direction of the bracket 3 and enabling it to move smoothly from within the positioning block 6 to within the limit block 14, avoiding the bracket 3 tilting during the process and making it difficult to complete the docking with the limit block 14.

[0025] A plurality of universal wheels 8 are connected to the bottom end of the conveying frame 4.

[0026] In this solution, the setting of the plurality of universal wheels 8 makes the conveying frame 4 more convenient to move.

[0027] The inner wall of the annular groove 9 is connected with a plurality of mounting blocks 11 arranged at equal intervals in a ring shape. The number of the mounting blocks 11 is the same as that of the limiting blocks 14, and the positions of the mounting blocks 11 correspond to those of the limiting blocks 14. One end of the conveying frame 4 close to the annular groove 9 is provided with a docking hole 7. An electromagnet is connected inside the docking hole 7. The outer end of the mounting block 11 is open, and a docking block 12 matching the docking hole 7 is slidably connected to the inner wall of the mounting block 11. The docking block 12 is made of a magnetic material. A spring 13 is arranged inside the mounting block 11, and two ends of the spring 13 are respectively connected with the inner wall of the mounting block 11 and the docking block 12.

[0028] In this solution, when the user moves the conveying frame 4 to one side of the corresponding bracket 3, the electromagnet in the docking hole 7 can be started, and then the position of the conveying frame 4 can be finely adjusted. When the docking hole 7 is aligned with the docking block 12, the docking block 12 will slide into the docking hole 7 under the influence of the magnetic force of the electromagnet and complete the docking with the docking hole 7. After the docking block 12 is docked with the docking hole 7, the limiting block 14 and the positioning block 6 will be kept completely aligned. At the same time, under the limiting action of the docking block 12, the conveying frame 4 cannot move further. With such a setting, during the process of the user replacing the bracket 3, it can be ensured that the positioning block 6 always maintains precise alignment with the limiting block 14, ensuring that the bracket 3 can smoothly slide from inside the positioning block 6 into the limiting block 14, effectively reducing the occurrence of jamming. At the same time, it also ensures that during the movement of the bracket 3, the conveying frame 4 will not be displaced due to the influence of the bracket 3, further improving the stability of the replacement process.

[0029] In this solution, when the docking block 12 moves outward from the mounting block 11, the spring 13 will be stretched. When the user turns off the electromagnet, the spring 13 will reset under the elastic force of the spring 13. The user does not need to start the electromagnet before moving the conveying frame 4 to one side of the corresponding bracket 3, so that the docking block 12 on the path during the movement of the conveying frame 4 will not be affected by the electromagnet.

[0030] The above are only embodiments of the present invention. Specific technical solutions and / or common knowledge such as characteristics known in the solutions are not described in detail here. It should be pointed out that for those skilled in the art, without departing from the technical solution of the present invention, several deformations and improvements can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the implementation effect of the present invention and the practicality of the patent. The protection scope required by this application should be subject to the content of its claims, and the specific implementation manners and the like recorded in the description can be used to interpret the content of the claims.
