Description

Technical Field

[0001] This utility model relates to the field of aerogel preparation technology, and in particular to a curing device for preparing fiber aerogel raw materials. Background Technology

[0002] Aerogel is the lightest known solid material in the world. Due to its extremely low thermal conductivity, durability, high temperature resistance, and explosion-proof properties, it has broad application prospects in aerospace, defense, green building, new energy, environmental governance, and solar thermal utilization.

[0003] Waste textiles are characterized by large output, low price, and difficulty in degradation. Through specific processing techniques, they can be transformed into aerogel materials with excellent properties. In preparing fiber aerogels, waste fibers are mixed evenly with a polyvinyl alcohol (PVA) solution, poured into a silicone resin mold, and then heated to cure. This process promotes cross-linking between the fibers and PVA, allowing hydrogen bonds to form between the hydroxyl groups of the polymer fibers and the PVA chains, thereby enhancing the overall structure and properties of the aerogel.

[0004] In existing small-scale production, the cured aerogel material often needs to be manually demolded. Since manual operation is often difficult to control the force and angle precisely, it is easy to damage the fragile aerogel structure, which not only reduces production efficiency but also increases the risk of product damage.

[0027] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. These drawings are simplified schematic diagrams, which are only used to illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0028] like Figure 1 , Figure 2 and Figure 3 As shown, a curing device for preparing fiber aerogel raw materials includes: a curing platform 1, a placement groove 11 formed on the top of the curing platform 1, and a curing mold 2 disposed inside the placement groove 11; the curing mold 2 includes: a mold block 21 snapped into the inside of the placement groove 11, a mold groove 22 formed on the top of the mold block 21, and a heating layer 23 embedded inside the mold block 21; a plurality of ejector pin holes 24 are formed on the inner sides of both the placement groove 11 and the mold groove 22; a movable groove 3 is formed on the inner side of the curing platform 1, a movable plate 31 is disposed on the inner side of the movable groove 3, a plurality of demolding ejector pins 32 are fixed on the top of the movable plate 31, the tops of the plurality of demolding ejector pins 32 are located inside the plurality of ejector pin holes 24, a connecting component for elastically connecting the movable plate 31 is disposed on the inner side of the movable groove 3, and a lifting component for driving the movable plate 31 to rise and fall is disposed on the bottom of the movable plate 31.

[0029] It should be noted that the number of ejector pins 32 is the same as the number of ejector pin holes 24. The top of the ejector pins 32 is flush with the bottom of the inner side of the mold groove 22. The mold block 21 and the placement groove 11 have the same shape and size. The heating layer 23 achieves heating by thermal radiation or thermal conduction. The uniformly mixed fiber and PVA blend solution is placed in the mold groove 22 on the top of the mold block 21. The heating layer 23 provides the required curing temperature for cross-linking. After curing and cross-linking are completed, with the cooperation of the lifting component and the connecting component, the movable plate 31 and several ejector pins 32 on the top of the movable plate 31 can be driven to move upward under the limit of several ejector pin holes 24. This can synchronously drive the aerogel material in the mold groove 22 to achieve stable and rapid demolding vertically upward. Moreover, the contact surface between several ejector pins 32 and the bottom of the aerogel material is small, making it easy to remove. The operation is simple and convenient, which not only improves production efficiency but also avoids the risk of product damage.

[0030] like Figure 3 As shown, in some embodiments, the connecting assembly includes: a plurality of telescopic rods 4 fixed between the top of the movable plate 31 and the inner side of the movable groove 3, and a return spring 41 sleeved on the side of the telescopic rods 4; one end of the return spring 41 is fixed to the top of the movable plate 31, and the other end is fixed to the inner side of the movable groove 3.

[0031] It should be noted that the telescopic rod 4 and the return spring 41 are fixed between the top of the movable plate 31 and the inner side of the movable groove 3, so that the movable plate 31 can be elastically connected. When the movable plate 31 moves up and down, it will squeeze the telescopic rod 4 upward to retract. At the same time, the return spring 41 will be subjected to the upward squeezing force. When the upward force applied to the movable plate 31 is removed, the return spring 41 will return to its original position, pushing the telescopic rod 4 to extend and return to its original position. This will drive several demolding ejector pins 32 to return to the same height as the bottom of the inner side of the mold groove 22, thus ensuring the reset effect after demolding.

[0032] In some embodiments, the lifting assembly includes: a hinge plate 5 fixed to the bottom of the movable plate 31, a pressure rod 51 hinged to the bottom of the hinge plate 5, and a connecting groove 52 formed on the front of the curing table 1; one end of the pressure rod 51 extends through the connecting groove 52 to the front of the curing table 1, and a fulcrum limiting member is provided between the pressure rod 51 and the connecting groove 52 to provide a connection point for the pressure rod 51.

[0033] It should be noted that when it is necessary to move the movable plate 31 and several demolding ejector pins 32 up and down, manually pressing down on one end of the pressure rod 51 located on the front of the curing table 1, with the cooperation of the fulcrum limiting component, can provide a connection point for the pressure rod 51. As a result, the end of the pressure rod 51 located inside the movable groove 3 will tilt upward. By hinged to the hinge plate 5 at the bottom of the movable plate 31, the lever principle can be used to easily move the movable plate 31 upward synchronously, thereby simultaneously moving several demolding ejector pins 32 to lift and remove the aerogel material, which helps to improve the operability in the test.

[0034] like Figure 4 As shown, in some embodiments, the fulcrum limiting member includes: a sliding groove 53 formed on the side of the pressure rod 51, and a connecting rod 54 fixed inside the sliding groove 53; the side of the connecting rod 54 is located inside the sliding groove 53.

[0035] It should be noted that the length of the sliding groove 53 is greater than the diameter of the connecting rod 54, which facilitates the sliding groove 53 to slide on the side of the connecting rod 54. When pressing the pressure rod 51, since the inner side of the sliding groove 53 on the side of the pressure rod 51 is located on the side of the connecting rod 54, it can provide a connection point when pressing the pressure rod 51, which makes it easy to use the lever principle to make one end of the pressure rod 51 tilt up and down.

[0036] like Figure 2 As shown, in some embodiments, the top of the mold block 21 is provided with a plurality of connecting countersunk holes 6, the bottom of the inner side of the placement groove 11 is provided with a plurality of positioning holes 61, the top of the plurality of connecting countersunk holes 6 is threaded with a plurality of screws 62, and the bottom end of the screws 62 is threadedly connected to the inner side of the positioning holes 61.

[0037] It should be noted that the number of connecting countersunk holes 6, positioning holes 61, and screws 62 is the same. After placing the mold block 21 in the curing mold 2 inside the placement groove 11, screws 62 are screwed in from the top of the connecting countersunk holes 6, and the bottom of the screws 62 are continuously screwed in until they are threaded into the inner side of the positioning hole 61. This can fix the curing mold 2 inside the placement groove 11, which facilitates the disassembly of the curing mold 2 or the replacement of curing molds 2 with other testing specifications, thus improving the flexibility of use.

[0038] like Figure 1 As shown, in some embodiments, the top of the curing table 1 is provided with a top cover 7. One side of the top cover 7 is hinged to the back of the curing table 1, and the other side is snapped into the front of the curing table 1. With the top cover 7, it can be rotated around the hinge point between the top cover 7 and the curing table 1, so that one side of the top cover 7 is snapped into the top of the curing table 1, thereby sealing the top of the curing table 1 and improving the temperature retention effect during curing.

[0039] In some embodiments, a handle 71 is fixed on one side of the top cover 7 for easy rotation of the top cover 7; the handle 71 makes it easy for the operator to hold the handle 71 and rotate the top cover 7.

[0040] In some embodiments, a base plate 8 is fixed to the bottom of the curing table 1, and a plurality of mounting holes 81 are provided on the surface of the base plate 8; the shape of the mounting holes 81 is one of circular, polygonal or irregular shape; the shape of the mounting holes 81 is preferably circular, and threads are provided on its inner wall to facilitate the use of screws or bolts and other connecting parts to cooperate with the mounting holes 81, and the curing table 1 is installed and positioned in the working position by the base plate 8.

[0041] In some embodiments, the mold block 21 is made of silicone resin. By using silicone resin, it has excellent heat resistance, cold resistance, weather resistance, and water repellency. In addition, it is colorless and transparent and has good adhesion and wear resistance, making it easy to use as an anti-sticking and demolding material.

[0042] In use, the mold block 21 in the curing mold 2 is placed inside the placement groove 11. Several screws 62 are screwed into the top of several connecting countersunk holes 6, and the bottom ends of the screws 62 are continuously screwed in until they are threaded into the inner side of the positioning hole 61. This fixes the curing mold 2 inside the placement groove 11. The uniformly mixed fiber and PVA blend solution is placed in the mold groove 22 on the top of the mold block 21. Holding the handle 71, the top cover 7 is rotated around the hinge point between the top cover 7 and the curing table 1, so that one side of the top cover 7 is engaged with the top of the curing table 1, thereby sealing the top of the curing table 1. The required cross-linking curing temperature is provided by the heating layer 23. After the curing and cross-linking are completed, the top cover 7 is opened, and the pressure rod 51 located on the front side of the curing table 1 is manually pressed down. Since the sliding groove 53 on the side of the pressure rod 51 is located inside the connecting groove 61, the curing mold 2 can be fixed inside the placement groove 11. The side of the connecting rod 54 can provide a connection point when the pressure rod 51 is pressed, so that the end of the pressure rod 51 located inside the movable groove 3 will tilt upward. By hinged to the hinge plate 5 at the bottom of the movable plate 31 through one end of the pressure rod 51, the movable plate 31 can be easily driven to move upward synchronously using the lever principle. When the movable plate 31 moves up and down, it will squeeze the telescopic rod 4 upward to retract. At the same time, the return spring 41 will be subjected to the upward extrusion force, which will drive the movable plate 31 and several demolding pins 32 on the top of the movable plate 31 to move upward under the limit of several ejector pin holes 24. This can synchronously drive the aerogel material in the mold groove 22 to achieve stable and fast demolding vertically upward. Moreover, the contact surface between the several demolding pins 32 and the bottom of the aerogel material is small, making it easy to remove. The operation is simple and convenient, which not only improves production efficiency, but also avoids the risk of product damage.
