[0031] 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. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0032] Referring to Figures 1 - 2 , an embodiment provided by the present invention: a cooling and shaping mold for sound-absorbing cotton, including a processing table 1. The inner top surface of the processing table 1 is fixedly connected with a lifting cylinder 2. The bottom end of the lifting cylinder 2 is provided with a pressing plate 3. When the lifting cylinder 2 is started, it can drive the pressing plate 3 below it to move downward. The inner bottom surface of the processing table 1 is fixedly connected with a mold base 4. After placing the sound-absorbing cotton waiting to be cooled into the mold base 4, the lifting cylinder 2 can be started to drive the pressing plate 3 to move downward to quickly press and shape the sound-absorbing cotton.

[0033] Referring to Figures 3 - 5 , the inner bottom surface of the mold base 4 is fixedly connected with an elastic member 5. The upper end of the elastic member 5 is fixedly connected with a moving plate 6. After placing the sound-absorbing cotton above the moving plate 6, the pressing plate 3 is moved downward to press and shape the sound-absorbing cotton. At this time, the moving plate 6 will move downward accordingly to compress the elastic member 5, causing the elastic member 5 to compress and generate elastic potential energy. When the pressing and shaping are completed and the pressing plate 3 moves upward to reset, the moving plate 6 will move upward to reset under the action of the elastic potential energy of the elastic member 5, so that the sound-absorbing cotton is removed from the mold base 4, and the upper surface of the moving plate 6 is flush with the upper surface of the mold base 4, which is convenient for the staff to take. At the same time, the staff can quickly clean the upper surface of the moving plate 6. The moving plate 6 is sleeved inside the mold base 4, and the outer wall of the moving plate 6 fits with the inner wall of the mold base 4. The left and right inner wall surfaces of the mold base 4 are fixedly connected with limiting rods 7, which can limit the movement of the moving plate 6 to prevent the moving plate 6 from moving downward excessively and exceeding the compression limit of the elastic member 5, resulting in damage to the elastic member 5.

[0034] A cooling unit is provided at the bottom of the movable plate 6. The movable plate 6 is made of a heat-conducting material. The cooling unit includes a blower 81. The blower 81 is fixedly connected to the right surface of the mold base 4. The left output end of the blower 81 penetrates through the right surface of the mold base 4. When the blower 81 is started, cold air can be blown into the bottom of the mold base 4. An air outlet 82 is provided on the left surface of the mold base 4. The air entering the interior of the mold base 4 can be discharged through the air outlet 82. A dust-proof net 83 is fixedly connected inside the air outlet 82. The outer wall of the dust-proof net 83 fits with the inner wall of the air outlet 82. The dust-proof net 83 can perform dust-proof treatment at the air outlet 82 to prevent dust and impurities in the outside air from entering the mold base 4, making it difficult to clean. When the cold air generated by the blower 81 passes through the bottom of the movable plate 6, it can take away the heat transferred from the sound-absorbing cotton to the movable plate 6, further accelerating the cooling and forming of the sound-absorbing cotton.

[0035] A cleaning unit is provided above the mold base 4. The cleaning unit includes a U-shaped chute 91. The U-shaped chute 91 is opened on the upper surface of the mold base 4. A roller 92 is slidably connected inside the U-shaped chute 91. The roller 92 can slide along the path of the U-shaped chute 91 inside the U-shaped chute 91. The right end of the roller 92 is fixedly connected to a U-shaped frame 93. When the U-shaped frame 93 moves, it can drive the roller 92 to move synchronously. A cleaning sponge 94 is fixedly connected to the left inner wall surface of the U-shaped frame 93. When the U-shaped frame 93 moves, it can drive the cleaning sponge 94 to move synchronously. The left surface of the cleaning sponge 94 fits with the right surface of the mold base 4. The width of the cleaning sponge 94 is greater than the width of the movable plate 6. Through the cooperation of the U-shaped chute 91 and the roller 92 provided, the movement of the U-shaped frame 93 can be guided and limited, so that the U-shaped frame 93 can move around the upper end of the mold base 4, preventing the U-shaped frame 93 from detaching from the mold base 4. When the U-shaped frame 93 moves along the upper side of the mold base 4, it can drive the cleaning sponge 94 to quickly wipe and clean the upper surface of the movable plate 6, preventing impurities from adhering to the upper surface of the movable plate 6 and damaging the flatness and forming quality of the sound-absorbing cotton when the sound-absorbing cotton is extruded and formed.

[0036] Refer to Figure 2, a water tank 10 is fixedly connected to the upper surface of the pressing plate 3. The pressing plate 3 and the moving plate 6 are both made of heat-conducting materials. The bottom of the water tank 10 is arranged in an open structure, so that the cold water entering the inside of the water tank 10 can be in full contact with the upper surface of the pressing plate 3. When the pressing plate 3 presses and forms the sound-absorbing cotton, the heat inside the sound-absorbing cotton can be transferred to the water tank 10 through the pressing plate 3, enabling the sound-absorbing cotton to be quickly cooled. The upper end of the water tank 10 is fixedly connected with a U-shaped circulation pipe 11. The inside of the U-shaped circulation pipe 11 is interconnected with the inside of the water tank 10. The upper and lower sides of the right surface of the water tank 10 are respectively fixedly connected with a water inlet pipe and a water outlet pipe. By setting the water inlet pipe and the water outlet pipe, an external water source can be connected to realize the filling and discharging of water inside the water tank 10. A circulation pump 12 is fixedly connected to the outside of the U-shaped circulation pipe 11. When the circulation pump 12 is started, it can extract the cold water inside the water tank 10 through the U-shaped circulation pipe 11 for circulating flow, thereby accelerating the heat exchange efficiency between the cold water and the upper surface of the pressing plate 3 and further improving the cooling efficiency of the sound-absorbing cotton.

[0037] Working principle: Place the sound-absorbing cotton waiting to be cooled above the moving plate 6. After filling the water tank 10 with cold water, start the lifting cylinder 2 to drive the pressing plate 3 to move downward to press the sound-absorbing cotton. During the downward movement of the pressing plate 3, it will press the moving plate 6, causing the moving plate 6 to move downward to press the elastic member 5. As the moving plate 6 moves downward to the position of the limiting rod 7, it will stop moving. At this time, the moving plate 6 and the pressing plate 3 will cooperate to press and form the sound-absorbing cotton. During the pressing process, the blower 81 and the circulation pump 12 can be started. While blowing air to the bottom surface of the moving plate 6, the cold water flow in the water tank 10 is accelerated to achieve the accelerated cooling of the sound-absorbing cotton and improve the cooling and forming efficiency. It can avoid the need to set ventilation nets and ventilation hoods inside the mold base 4, which may easily cause the ventilation nets and ventilation hoods to be caught in the sound-absorbing cotton during the pressing of the sound-absorbing cotton, thereby damaging the flatness of the sound-absorbing cotton and affecting the product quality of the sound-absorbing cotton. After the cooling and forming are completed, start the lifting cylinder 2 to drive the pressing plate 3 to move upward for resetting. At this time, the moving plate 6 will automatically reset upward under the elastic potential energy of the elastic member 5, thereby lifting the sound-absorbing cotton upward, which is convenient for the staff to take. At the same time, the upper surface of the reset moving plate 6 will be on the same horizontal plane as the upper surface of the mold base 4. At this time, when the staff pulls the U-shaped frame 93, the cleaning sponge 94 can quickly wipe and clean the upper surface of the moving plate 6, avoiding impurities adhering to the upper surface of the moving plate 6 and affecting the flatness of the sound-absorbing cotton after pressing and forming. The operation is simple, and the whole process ends.

[0038] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or perform equivalent replacements on some of the technical features.
