[0018] The present invention provides a shaping tooling for the production of energy-saving air ducts for molding. It has the following beneficial effects:
[0019] 1. The shaping tooling for the production of the molded energy-saving air duct places the duct at the position of the outer wall of the expansion air chamber. The air pump injects air into the rotating main bearing pipe, causing the expansion air chamber to expand, and the inner wall of the expansion air chamber to closely adhere to the inner wall of the air duct. This can avoid the deformation of the air duct caused by conventional accumulation. At the same time, the driving motor drives the rotating main bearing pipe to rotate, causing the air duct on the outer wall of the expansion air chamber to rotate together, making the outer wall of the air duct expand uniformly under the action of centrifugal force, accelerating the gas flow on the outer side of the air duct, accelerating the shaping of the air duct, and improving the final product quality.
[0020] 2. The shaping tooling for the production of the molded energy-saving air duct makes the outer wall of the air duct fit the outer wall of the rotating pipe. The fixing frame is pushed to rotate by the air duct through friction, which can correct the deviation of the air duct, promote the air duct to become round. At the same time, the spiral plate rotates to push the air to flow inside the rotating pipe, playing a role in cooling the rotating pipe. When the rotating pipe contacts the air duct, it cools the outer wall of the air duct, promoting the shaping of the air duct and improving the final product quality.
[0021] 3. The shaping tooling for the production of the molded energy-saving air duct uses gas to push the push plate to quickly move upward along the inner wall of the rotating main bearing pipe, and then makes it flow towards the inner wall of the expansion air chamber and flow downward along the inner wall of the expansion air chamber. The inclined plate will slow down the speed of the liquid flowing down from the expansion air chamber, cooling the inner wall of the air duct, promoting the shaping of the air duct, and improving the final product quality.
[0022] 4. The shaping tooling for the production of the molded energy-saving air duct is driven to rotate passively by the expansion air chamber, which will cause the liquid to slide inside the expansion air chamber, making it contact the inner wall of the expansion air chamber more fully and evenly. And because the conveyor belt is inclined, it will have the effect of pushing the liquid upward during rotation, slowing down the speed of the liquid flowing down from the expansion air chamber, enabling the liquid to absorb the heat of the air duct for a longer time, improving the cooling effect, promoting the shaping of the air duct, and improving the final product quality.

[0032] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.
[0033] Examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions from beginning to end. The embodiments described below by referring to the accompanying drawings are exemplary and are intended to explain the present invention, and should not be construed as a limitation of the present invention.
[0034] Embodiment 1: Please refer to Figure 1-6 , the present invention provides a technical solution: A shaping tool for the production of a molded energy-saving air duct, including a fixed table 1, a rotating assembly 2 is movably connected to the top of the fixed table 1, and a cooling mechanism 3 is fixedly connected to the top of the fixed table 1;
[0035] The rotating assembly 2 includes:
[0036] A rotating main bearing pipe 201, the rotating main bearing pipe 201 is movably connected to the top of the fixed table 1, and the rotating main bearing pipe 201 is rotationally connected to the fixed table 1 through a bearing;
[0037] An expansion air chamber 202, the expansion air chamber 202 is fixedly connected to the outer wall of the fixed table 1, the normal shape of the expansion air chamber 202 is cylindrical, and the expansion air chamber 202 will expand as the internal air pressure increases;
[0038] The air pump 204 is arranged at the bottom of the fixed platform 1.
[0039] Place the air duct removed from the mold at the position on the outer wall of the expansion air chamber 202. Inject air into the interior of the rotating main bearing pipe 201 through the air pump 204, and let the gas enter the interior of the expansion air chamber 202 through the holes on the rotating main bearing pipe 201, so that the expansion air chamber 202 expands, making the inner wall of the expansion air chamber 202 closely adhere to the inner wall of the air duct, fixing and supporting the air duct, which can avoid the deformation of the air duct caused by conventional stacking. After the air duct cools down, the air pump 204 discharges the air inside the expansion air chamber 202 through the rotating main bearing pipe 201 for cooling.
[0040] The bottom of the rotating main bearing pipe 201 is movably connected by a bearing to a connecting pipe 203, and the connecting pipe 203 is fixedly connected to the air pump 204.
[0041] The air pump 204 can fill air into the interior of the rotating main bearing pipe 201 through the connecting pipe 203, and suck air out of the rotating main bearing pipe 201.
[0042] A driving motor 208 is fixedly connected inside the fixed platform 1. The outer wall of the driving motor 208 is movably connected to a conveyor belt 209, and the conveyor belt 209 is movably connected to the rotating main bearing pipe 201.
[0043] After the air duct is fixed by the expansion of the expansion air chamber 202, the driving motor 208 drives the rotating main bearing pipe 201 to rotate through the conveyor belt 209, and drives the air duct on the outer wall of the expansion air chamber 202 to rotate together through the fixing effect with the expansion air chamber 202, which will cause the outer wall of the air duct to be affected by the centrifugal force, and the force acts evenly outward, while accelerating the gas flow outside the air duct and accelerating the shaping of the air duct.
[0044] The top of the rotating main bearing pipe 201 is movably connected to a pressure relief piece 205. The bottom of the pressure relief piece 205 is fixedly connected to a reset frame 207 inside the expansion air chamber 202. The top of the reset frame 207 is fixedly connected to a spring 206, and the top of the spring 206 is fixedly connected to the inner top of the expansion air chamber 202.
[0045] When the air pump 204 sends gas into the interior of the rotating main bearing pipe 201 through the connecting pipe 203, the expansion air chamber 202 expands and fits with the inner wall of the air duct. Subsequently, the air pressure inside the expansion air chamber 202 gradually increases until it pushes the pressure relief piece 205 outward and compresses the spring 206, discharging the excess gas from the interior of the expansion air chamber 202 to avoid damage to the air duct caused by excessive pressure inside the expansion air chamber 202.
[0046] Embodiment 2: Please refer to Figure 1-8 , on the basis of Embodiment 1, the present invention provides a technical solution:
[0047] The cooling mechanism 3 includes a fixed frame 301, which is fixedly connected to the top of the fixed platform 1. The outer wall of the fixed frame 301 is movably connected with a rotating pipe 302, and a spiral plate 303 is fixedly connected inside the rotating pipe 302.
[0048] After the expansion air chamber 202 fixes the air duct and drives the air duct to rotate, the outer wall of the air duct will be in contact with the outer wall of the rotating pipe 302. Since the position of the fixed frame 301 is fixed, when the air duct rotates, the rotating pipe 302 will be driven to rotate by friction. When the air duct rotates, the rotating pipe 302 will play a role in correcting the deviation of the air duct, so that the air duct will be pushed to become round during the rotation process. At the same time, when the rotating pipe 302 rotates, it will drive the internal spiral plate 303 to rotate, pushing the air to flow inside the rotating pipe 302, which plays a role in cooling the rotating pipe 302. This makes the rotating pipe 302 play a role in cooling the air duct when it is in contact with the air duct, promoting the shaping of the air duct.
[0049] A push plate 304 is movably connected inside the expansion air chamber 202. During use, a liquid with good thermal conductivity is added to the top of the push plate 304. The top of the push plate 304 is movably connected with a movable plate 305. The push plate 304 is provided with corresponding openings at the bottom of the movable plate 305. An outer ring plate 306 is fixedly connected to the outer wall of the rotating main pipe 201, and a centrifugal plate 307 is fixedly connected to the top of the outer ring plate 306. Openings are fixedly connected to the outer wall of the rotating main pipe 201 at positions corresponding to the outer ring plate 306, and limiting protrusions are arranged on the inner wall of the rotating main pipe 201 at positions corresponding to the outer ring plate 306. An inclined plate 309 is fixedly connected to the inner wall of the expansion air chamber 202.
[0050] When the air pump 204 blows air into the inside of the rotating main bearing pipe 201, it will cause the air pressure at the bottom of the push plate 304 to increase, causing the push plate 304 to quickly move upward along the inner wall of the rotating main bearing pipe 201 until the push plate 304 is intercepted by the corresponding limit protrusion. At this time, the expansion air chamber 202 will be expanded by the gas pressed into the expansion air chamber 202 by the top of the push plate 304. At the same time, the drive motor 208 drives the air duct to start rotating through the conveyor belt 209, and the liquid will flow outward. The outer ring plate 306 is driven to rotate by the rotating main bearing pipe 201 and generates an outward centrifugal force on the liquid through the push of the centrifugal plate 307. At the same time, driven by the gas filled into the expansion air chamber 202 by pushing open the movable plate 305, it flows toward the inner wall of the expansion air chamber 202 and flows downward along the inner wall of the expansion air chamber 202. The inclined plate 309 will slow down the speed of the liquid flowing down from the expansion air chamber 202. At the same time, due to the passive rotation of the expansion air chamber 202, the liquid will slide inside the expansion air chamber 202, making more full and uniform contact with the inner wall of the expansion air chamber 202. And because the conveyor belt 209 is an inclined structure, it will have the effect of pushing the liquid upward during rotation, slowing down the speed of the liquid flowing down from the expansion air chamber 202. These liquids will absorb the heat of the air duct through the expansion air chamber 202 to accelerate the cooling of the air duct and promote the shaping of the air duct.
[0051] A connecting rope 308 is fixedly connected to the bottom of the push plate 304. A blocking ring 310 is movably connected to the inside of the rotating main bearing pipe 201 at the bottom of the air pump 204. The top of the blocking ring 310 is fixedly connected to the connecting rope 308. An opening is provided at the corresponding position of the outer wall of the rotating main bearing pipe 201 where the blocking ring 310 is located.
[0052] A movable magnet 312 is fixedly connected to the inner wall of the blocking ring 310. A fixed magnet 311 is fixedly connected to the outer wall of the rotating main bearing pipe 201 at the corresponding position of the movable magnet 312.
[0053] When the pushing plate 304 is pushed upward by air pressure, it will pull the blocking ring 310 upward together through the connecting rope 308. When the pushing plate 304 is intercepted by the corresponding limiting protrusion, at this time, the blocking ring 310 will be straightened by the connecting rope 308 at the corresponding position of the fixed magnet 311. Due to the mutual attraction between the fixed magnet 311 and the movable magnet 312, the fixed magnet 311 will block the corresponding opening, preventing the liquid from flowing out of the expansion air chamber 202 through the opening, and making the liquid flowing from the expansion air chamber 202 to the bottom fit against the outer wall of the rotating main bearing pipe 201. Since the liquid continuously flows out of the rotating main bearing pipe 201, the temperature of the rotating main bearing pipe 201 will be relatively low, which can dissipate heat from the liquid. After the air duct is cooled, the air pump 204 will extract the gas inside the rotating main bearing pipe 201 through the connecting pipe 203, causing the movable plate 305 to fit against the pushing plate 304 under the action of air pressure and move downward together. When the pushing plate 304 meets the blocking ring 310, the gas will push the blocking ring 310 downward together through the pushing plate 304, causing the blocking ring 310 to no longer block the opening, and allowing the liquid to flow back to the top of the pushing plate 304 through the opening. After the air duct is shaped, the air duct is removed.
[0054] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
