[0012] The present invention provides a molding tool for producing energy-saving molded air ducts. It has the following beneficial effects: 1. The molding tooling for the production of molded energy-saving air ducts places the tube at the position of the outer wall of the expansion air chamber, and injects air into the rotating main bearing tube through an air pump to expand the expansion air chamber, so that the inner wall of the expansion air chamber is close to the inner wall of the air duct, thereby avoiding deformation of the air duct caused by conventional accumulation. At the same time, the driving motor drives the rotating main bearing tube to rotate, so that the air duct on the outer wall of the expansion air chamber rotates together, so that the outer wall of the air duct is affected by centrifugal force and expands outward evenly under the action of force, while accelerating the gas flow outside the air duct, accelerating the shaping of the air duct, and improving the final product quality.

[0013] 2. The molding tooling for the production of the molded energy-saving air duct makes the outer wall of the air duct fit with the outer wall of the rotating tube. The fixed frame is pushed to rotate by the air duct through friction, which can correct the deviation of the air duct and promote the air duct to become round. At the same time, the spiral plate rotates to promote the air circulation inside the rotating tube, which cools the rotating tube. This makes the rotating tube cool the outer wall of the air duct when it contacts the air duct, promotes the shaping of the air duct, and improves the final product quality.

[0014] 3. The molding tooling used for the production of molded energy-saving air ducts uses gas to push the push plate to move rapidly upward along the inner wall of the rotating main bearing pipe, and then flows to the inner wall of the expanding air chamber and flows downward on the inner wall of the expanding air chamber. The inclined plate will slow down the speed of the liquid flowing down from the expanding air chamber, cool the inner wall of the air duct, promote the shaping of the air duct, and improve the final product quality.

[0015] 4. The molding tooling used for the production of the molded energy-saving air duct is passively driven to rotate by the expansion gas bin, which will make the liquid slide inside the expansion gas bin and contact the inner wall of the expansion gas bin more fully and evenly. In addition, since the conveyor belt is an inclined structure, it will push the liquid upward when rotating, slowing down the speed of the liquid flowing downward from the expansion gas bin, so that the liquid can absorb the heat of the air duct for a longer time, improve the cooling effect, promote the shaping of the air duct, and improve the final product quality.

DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0019] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0020] Example 1: Please refer to Figure 1-6 The present invention provides a technical solution: a molding tool for producing energy-saving molded air ducts, comprising a fixed platform 1, a rotating component 2 is movably connected to the top of the fixed platform 1, and a cooling mechanism 3 is fixedly connected to the top of the fixed platform 1; The rotating assembly 2 comprises: The rotating main bearing pipe 201 is movably connected to the top of the fixed platform 1, and the rotating main bearing pipe 201 is rotatably connected to the rotating main bearing pipe 201 through a bearing; An expansion gas chamber 202, which is fixedly connected to the outer wall of the fixed platform 1. The expansion gas chamber 202 is cylindrical in shape. The expansion gas chamber 202 will expand as the internal air pressure increases. The air pump machine 204 is arranged at the bottom of the fixing platform 1 .

[0021] The air duct removed from the mold is placed on the outer wall of the expansion gas bin 202, and air is injected into the rotating main supporting pipe 201 through the air pump 204. The gas is allowed to enter the expansion gas bin 202 through the holes on the rotating main supporting pipe 201 to expand the expansion gas bin 202. The inner wall of the expansion gas bin 202 is allowed to fit closely against the inner wall of the air duct to provide fixed support for the air duct, thereby avoiding deformation of the air duct caused by conventional stacking. After the air duct is cooled, the air pump 204 discharges the air inside the expansion gas bin 202 through the rotating main supporting pipe 201 for cooling.

[0022] The bottom of the rotating main bearing pipe 201 is movably connected to a connecting pipe 203 through a bearing, and the connecting pipe 203 is fixedly connected to the air pump 204.

[0023] The air pump 204 can fill air into the rotating main bearing pipe 201 through the connecting pipe 203 , and suck air out of the rotating main bearing pipe 201 .

[0024] A driving motor 208 is fixedly connected inside the fixed platform 1 , and a conveyor belt 209 is movably connected to the outer wall of the driving motor 208 , and the conveyor belt 209 is movably connected to the rotating main bearing pipe 201 .

[0025] After the air duct is fixed by expanding the expansion gas chamber 202, the driving motor 208 drives the rotating main supporting pipe 201 to rotate through the conveyor belt 209, and the air duct on the outer wall of the expansion gas chamber 202 is rotated together with the fixing effect of the expansion gas chamber 202, which will make the outer wall of the air duct be affected by the centrifugal force, and expand outward evenly under the action of the force, while accelerating the gas flow on the outside of the air duct and accelerating the shaping of the air duct.

[0026] A pressure relief plate 205 is movably connected to the top of the rotating main bearing tube 201, and the bottom of the pressure relief plate 205 is located inside the expansion gas chamber 202 and is fixedly connected to a reset frame 207, 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 top of the expansion gas chamber 202.

[0027] When the air pump 204 delivers gas into the rotating main bearing pipe 201 through the connecting pipe 203, the expansion gas chamber 202 expands and fits the inner wall of the air duct. Then, the air pressure inside the expansion gas chamber 202 gradually increases until it pushes the pressure relief plate 205 outward and compresses the spring 206, thereby discharging excess gas from the expansion gas chamber 202 to avoid damage to the air duct due to excessive pressure inside the expansion gas chamber 202.

[0028] Example 2: Please refer to Figure 1-8 Based on the first embodiment, the present invention provides a technical solution: The cooling mechanism 3 comprises a fixing frame 301 , which is fixedly connected to the top of the fixing platform 1 , and a rotating tube 302 is movably connected to the outer wall of the fixing frame 301 , and a spiral plate 303 is fixedly connected to the inside of the rotating tube 302 .

[0029] After the expansion gas chamber 202 fixes the air duct, it drives the air duct to rotate, which will make the outer wall of the air duct fit with the outer wall of the rotating tube 302. Since the position of the fixing frame 301 is fixed, the fixing frame 301 will be driven to rotate by friction when the air duct rotates, so that the fixing frame 301 can correct the deviation of the air duct when the air duct rotates, so that the air duct is pushed to become round during the rotation process. At the same time, when the rotating tube 302 rotates, it will bring the internal spiral plate 303 to rotate, and promote the air to circulate inside the rotating tube 302, which has a cooling effect on the rotating tube 302. This makes the rotating tube 302 cool the air duct when it contacts the air duct, thereby promoting the shaping of the air duct.

[0030] The expansion gas chamber 202 is movably connected with a push plate 304 inside. When in use, a liquid with good thermal conductivity will be 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 located at the bottom of the movable plate 305 and a corresponding opening is provided. The outer wall of the rotating main bearing tube 201 is fixedly connected with an outer ring plate 306. The top of the outer ring plate 306 is fixedly connected with a centrifugal plate 307. The outer wall of the rotating main bearing tube 201 is fixedly connected with an opening at a corresponding position of the outer ring plate 306. The inner wall of the rotating main bearing tube 201 is provided with a limiting protrusion at a corresponding position of the outer ring plate 306. The inner wall of the expansion gas chamber 202 is fixedly connected with an inclined plate 309.

[0031] When the air pump 204 blows air into the rotating main bearing tube 201, the air pressure at the bottom of the push plate 304 increases, causing the push plate 304 to move rapidly upward along the inner wall of the rotating main bearing tube 201 until the push plate 304 is intercepted by the corresponding limit protrusion. At this time, the expansion gas chamber 202 is expanded by the gas pressed into the expansion gas chamber 202 by the top of the push plate 304. At the same time, the driving motor 208 drives the air duct to start rotating through the conveyor belt 209, and the liquid flows outward. The outer ring plate 306 is driven to rotate by the rotating main bearing tube 201 and the liquid generates an outward centrifugal force through the push of the centrifugal plate 307. At the same time, the movable plate 305 is opened to push the expansion gas chamber 202 to the expansion gas chamber 202. Driven by the gas filled in the bin 202, the liquid flows toward the inner wall of the expansion bin 202 and flows downward on the inner wall of the expansion bin 202. The inclined plate 309 will slow down the speed of the liquid flowing down from the expansion bin 202. At the same time, due to the passive rotation of the expansion bin 202, the liquid will slide inside the expansion bin 202 and contact the inner wall of the expansion bin 202 more fully and evenly. Moreover, since the conveyor belt 209 is an inclined structure, it will push the liquid upward when rotating, slowing down the speed of the liquid flowing downward from the expansion bin 202. These liquids will absorb the heat of the air duct through the expansion bin 202 to accelerate the cooling of the air duct and promote the shaping of the air duct.

[0032] A connecting rope 308 is fixedly connected to the bottom of the push plate 304, and a blocking ring 310 is movably connected to the bottom of the air pump 204 inside the rotating main supporting pipe 201. The top of the blocking ring 310 is fixedly connected to the connecting rope 308, and an opening is provided on the outer wall of the rotating main supporting pipe 201 at a position corresponding to the blocking ring 310.

[0033] A movable magnet 312 is fixedly connected to the inner wall of the blocking ring 310 , and a fixed magnet 311 is fixedly connected to the outer wall of the rotating main bearing tube 201 at a position corresponding to the movable magnet 312 .

[0034] When the push plate 304 is pushed upward by the air pressure, the blocking ring 310 will be pulled upward together through the connecting rope 308. When the push plate 304 is intercepted by the corresponding limiting protrusion, the blocking ring 310 will be straightened by the connecting rope 308 to the corresponding position of the fixed magnet 311. The fixed magnet 311 and the movable magnet 312 will attract each other and cause the fixed magnet 311 to block the corresponding opening to prevent the liquid from flowing out from the inside of the expansion gas chamber 202 through the opening, and make the liquid flowing to the bottom from the expansion gas chamber 202 fit the outer wall of the rotating main bearing tube 201. The outflowing liquid will make the temperature of the rotating main bearing pipe 201 lower, which can dissipate heat and cool 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, which will make the movable plate 305 fit with 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, and the blocking ring 310 will no longer block the opening, and let the liquid flow back to the top of the pushing plate 304 through the opening. After the air duct is finalized, the air duct can be removed.

[0035] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
