Description

Technical Field

[0001] This invention relates to the field of aerogel felt production technology, specifically to an aerogel felt mold release device and a release method. Background Technology

[0002] Aerogel felt is a flexible thermal insulation felt made primarily of nano-silica or metallic aerogel, combined with carbon fiber, ceramic glass fiber wool, or pre-oxidized fiber felt through a special process. It is characterized by low thermal conductivity and certain tensile and compressive strength, making it a novel type of pipe insulation material.

[0003] In response, Chinese patent CN214725680U proposes an aerogel felt mold demolding device and aerogel production equipment. This aerogel felt mold demolding device includes a mounting frame, a pushing drive mechanism, an ejection mechanism, and a fixing hoop. The fixing hoop is mounted on the mounting frame and remains fixed in position. The fixing hoop can fix the cylindrical aerogel felt mold. The pushing drive mechanism drives the ejection mechanism to eject the aerogel felt towards the fixing hoop, causing the aerogel felt in the mold to move relative to the mold, thereby demolding the aerogel felt. This is convenient and labor-saving. However, in actual use, since the ejection mechanism simply applies a force to the aerogel felt, when the aerogel felt moves under the pushing force, uneven force may cause deformation and breakage. Summary of the Invention

[0004] The purpose of this invention is to provide a demolding device and demolding method for aerogel felt molds, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A demolding device for an aerogel felt mold includes:

[0007] A processing rack, and a mold rotatably mounted on the processing rack;

[0008] Also includes:

[0012] A strength adjustment mechanism is provided on the mold and connected to the horizontal opening and closing mechanism and the ejection assembly. The ejection assembly can adjust the supporting force of the horizontal opening and closing mechanism on the support plate through the strength adjustment mechanism.

[0015] As a further embodiment of the present invention: the follow-up translation mechanism includes a guide post installed on the side wall of the mold, a guide sleeve slidably installed on the guide post, a movable plate and a rack plate provided on the side wall of the guide sleeve, and a guide assembly connected to the hollow rod provided on the movable plate.

[0016] As a further embodiment of the present invention: the guiding component includes a guide groove formed on the movable plate, a guide rod that cooperates with the guide groove is rotatably mounted on the movable plate, a fixing block that abuts against the guide rod is provided on the movable plate, and a limiting post that slides and engages with the guide groove is provided on the hollow rod.

[0017] As a further embodiment of the present invention: the rotating assembly includes a first rotating rod rotatably mounted on the mold, the first rotating rod being provided with a gear and a first bevel gear, the gear meshing with the rack plate;

[0018] It also includes a second rotating rod and a third rotating rod rotatably mounted on the mold. The second rotating rod is connected to the third rotating rod via a first belt. The second rotating rod is provided with a second bevel gear that meshes with the first bevel gear.

[0019] As a further embodiment of the present invention: the horizontal opening and closing mechanism includes a second spiral groove formed on the third rotating rod, a symmetrically arranged sliding sleeve is slidably mounted on the third rotating rod, a second limiting block is provided inside the sliding sleeve and slidably engaged with the second spiral groove, a guide ring is provided on the side wall of the sliding sleeve and slidably connected to the second rotating rod, and an elastic support component is provided on the sliding sleeve.

[0020] As a further embodiment of the present invention: the elastic support assembly includes a support sleeve mounted on the sliding sleeve, a support rod slidably mounted inside the support sleeve, the support rod being connected to the support plate, and a movable ring slidably mounted on the support sleeve;

[0021] It also includes a slot formed on the support sleeve, a limiting ring that is slidably connected to the slot on the support rod, and a second spring sleeved on the support sleeve, with the two ends of the second spring abutting against the movable ring and the limiting ring respectively.

[0022] As a further embodiment of the present invention: the strength adjustment mechanism includes a vertical groove and a first spiral groove formed on the outer circumference of the hollow rod, the ends of the vertical groove and the first spiral groove being connected to each other, a first limiting block being provided inside the rotating sleeve and slidingly engaging with the vertical groove and the first spiral groove, a fourth rotating rod being rotatably mounted on the mold, a second belt connected to the rotating sleeve being sleeved on the fourth rotating rod, and a lifting assembly connected to the movable ring being provided on the fourth rotating rod.

[0023] As a further embodiment of the present invention: the lifting assembly includes a third spiral groove formed on the fourth rotating rod, a movable sleeve is slidably mounted on the fourth rotating rod, a third limiting block is provided inside the movable sleeve and slidably fitted with the third spiral groove, and an adjusting plate is provided on the movable sleeve and sleeved on the supporting sleeve, the adjusting plate abutting against the movable ring.

[0024] A demolding method for an aerogel felt mold demolding device includes the following steps:

[0025] Step 1: After the aerogel felt is placed in the mold and formed, the ejector plate can be controlled to move toward the mold opening through the ejector assembly to eject the aerogel felt;

[0026] Step 2: The ejector component will also drive the follow-up translation mechanism to move, and control the translation opening and closing mechanism by rotating the component, so that the two support plates move toward each other;

[0027] Step 3: When the side walls of the support plates abut against each other, the mold is sealed under the action of the support plates. As the ejector plate continues to move, the aerogel felt is placed between the support plate and the ejector plate.

[0028] Step 4: At this time, the mold opening direction is rotated to face the processing frame, and the ejector component continues to control the movement of the ejector plate, so that the aerogel felt is detached from the mold. At the same time, the ejector component will also reduce the downward pressure of the support plate on the aerogel felt through the strength adjustment mechanism.

[0029] Step 5: When the ejector assembly controls the ejector plate to move toward the initial position, the follow-up translation mechanism causes the support plate to move away from each other until the aerogel felt is detached from the mold.

[0030] Compared with the prior art, the beneficial effects of the present invention are: the present application can ensure that the glass fiber mat will not be deformed and damaged during ejection by the cooperation of the support plate and the ejector plate. When the ejector assembly moves, the ejector plate controls the glass fiber mat to move towards the mold opening. The ejector assembly also drives the rotating assembly to move through the follow-up translation mechanism, so as to control the two support plates to move towards each other through the horizontal opening and closing mechanism. When the side walls of the two support plates are in contact with each other and block the mold opening, the ejector plate continues to move. At this time, the support plate stops moving. When the ejector plate... When the fiberglass mat is pushed to the position where it abuts the support plate, the mold can be controlled to flip. The ejector assembly continues to control the movement of the ejector plate until the fiberglass mat is removed from the mold. At this time, the ejector assembly moves toward the initial position and the horizontal opening and closing mechanism is reset by the follow-up translation mechanism and the rotation assembly to control the support plate to move away from the mold. During this process, the ejector plate always provides a force to the fiberglass mat in the direction of the support plate to ensure that the fiberglass mat does not deform until the support plate separates from the fiberglass mat. Under the action of gravity, the fiberglass mat separates from the ejector plate, thereby achieving the demolding effect.

[0031] During the process of the ejector plate controlling the glass fiber mat to detach from the mold, the ejector assembly also adjusts the compressive force of the support plate on the glass fiber mat through the strength adjustment mechanism to prevent the glass fiber mat from breaking due to excessive compressive force.

[0048] Please see Figures 1-13 In this embodiment of the invention, an aerogel felt mold demolding device includes:

[0049] A processing frame 1, and a mold 2 rotatably mounted on the processing frame 1;

[0050] Also includes:

[0051] Please see Figures 1-5 , Figure 9 , Figure 11An ejector assembly is disposed on the mold 2. An ejector plate 7 is connected to the ejector assembly and is slidably and sealingly connected to the mold 2. The ejector assembly includes a rotating sleeve 3 rotatably mounted on the bottom of the mold 2. A hollow rod 4 penetrating the mold 2 is slidably mounted inside the rotating sleeve 3. A movable rod 5 is slidably mounted inside the hollow rod 4 and is connected to the ejector plate 7. The assembly also includes a first spring 9 installed inside the hollow rod 4 and abutting against the movable rod 5. A connecting plate 6 is provided at the end of the hollow rod 4. A cylinder 8 connected to the connecting plate 6 is provided on the mold 2.

[0052] In detail, when producing aerogel felt, the raw materials need to be mixed in a certain proportion and added into the mold 2 containing glass fiber felt. The glass fiber felt will be placed on the surface of the ejector plate 7. After standing for a certain period of time, the surface of the glass fiber felt will gel, forming wet gel fiber felt. At this time, the material needs to be removed from the mold 2. In the initial state, under the action of the cylinder 8, the hollow rod 4 is controlled by the connecting plate 6 to be at the end of its stroke away from the mold 2. At the same time, due to the gravity of the ejector plate 7, the first spring 9 is slightly compressed. When ejection is required, under the action of the cylinder 8, the hollow rod 4 is driven to move by the connecting plate 6, which in turn drives the movable rod 5 to move by the first spring 9. The movable rod 5 also drives the ejector plate 7 to move. Under the action of the ejector plate 7, the glass fiber felt placed in the mold 2 is pushed in the direction of detaching from the mold 2.

[0053] Preferably, since the dimensions of the ejector plate 7 are the same as the internal dimensions of the mold 2, the fiberglass mat will not deform when it is pushed, ensuring that it will not be damaged during demolding.

[0054] Please see Figures 1-5 , Figures 7-10 A follow-up translation mechanism is disposed on the side wall of the mold 2 and connected to the ejection assembly. The follow-up translation mechanism includes a guide post 11 installed on the side wall of the mold 2. A guide sleeve 12 is slidably installed on the guide post 11. A movable plate 13 and a rack plate 16 are provided on the side wall of the guide sleeve 12. A guide assembly connected to the hollow rod 4 is provided on the movable plate 13. The guide assembly includes a guide groove formed on the movable plate 13. A guide rod 14 that cooperates with the guide groove is rotatably installed on the movable plate 13. A fixing block 15 that abuts against the guide rod 14 is provided on the movable plate 13. A limiting post 10 that slidably engages with the guide groove is provided on the hollow rod 4.

[0055] It should be noted that the guide groove can be divided into multiple sections, namely the first straight groove 1301, the first inclined groove 1302, the second straight groove 1303, and the second inclined groove 1304. One end of the first inclined groove 1302 is connected to the end of the second straight groove 1303, and the other end is connected to the first straight groove 1301. One end of the second inclined groove 1304 is connected to the end of the first straight groove 1301, and the other end is connected to the second straight groove 1303. Two guide rods 14 are provided, one of which is located at the connection position between the first inclined groove 1302 and the first straight groove 1301, and the other is located at the connection position between the second inclined groove 1304 and the second straight groove 1303. A torsion spring is sleeved on the rotating shaft of the guide rod 14. Under the action of the torsion spring, the guide rod 14 abuts against the fixing block 15.

[0056] In the initial state, under the action of cylinder 8, the hollow rod 4 is located at the end of its stroke away from the mold 2, and the limiting post 10 is located at the end of its stroke on the side of the first straight groove 1301 away from the second inclined groove 1304. When demolding is required, under the action of cylinder 8, the hollow rod 4 is controlled to move along the length direction of the rotating sleeve 3, so as to control the glass fiber mat to perform demolding through the ejector plate 7. The hollow rod 4 will also drive the limiting post 10 to move, so that the limiting post 10 slides along the first straight groove 1301. When the limiting post 10 moves to the position of abutting with one of the guide rods 14, the guide rod 14 will not rotate because it abuts with the fixing block 15.

[0057] Therefore, the limiting post 10 will disengage from the first straight groove 1301 and enter the first inclined groove 1302, so that the guide sleeve 12 can be controlled by the movable plate 13 to move along the length direction of the guide post 11. The guide sleeve 12 and the guide post 11 have a guiding function to ensure that the movable plate 13 will not deviate during movement. The guide sleeve 12 will also drive the rack plate 16 to move, so as to drive the rotating component to move. The rotating component will drive the horizontal opening and closing mechanism to move, so as to control the two support plates 28 to move towards each other. When the limiting post 10 disengages from the first inclined groove 1302 and enters the second straight groove 1303, the movable plate 13 will no longer move, so that the rotating component will no longer move. At this time, the two support plates 28 will just move to the position of mutual contact to seal the opening of the mold 2.

[0058] Preferably, a conveyor belt for receiving the demolded glass fiber mat can be provided below the mold 2. The ejector plate 7 continues to move, driving the glass fiber mat to continue moving, so that the limiting post 10 moves along the length direction of the second straight groove 1303. When the glass fiber mat moves to the position of being in contact with the support plate 28, the glass fiber mat will be placed between the support plate 28 and the ejector plate 7 to ensure that the glass fiber mat will not deform. At this time, the mold 2 flips so that the opening of the mold 2 faces the processing frame 1. The cylinder 8 continues to move to control the glass fiber mat to continue moving through the ejector plate 7. When the elastic potential energy of the first spring 9 is greater than the supporting force on the support plate 28, the ejector plate 7 will control the support plate 28 to move through the glass fiber mat, so that the glass fiber mat is removed from the mold 2.

[0059] During this process, the limiting post 10 will abut against another guide rod 14, causing the guide rod 14 to rotate and separate from the fixing block 15, ensuring that the limiting post 10 can continue to slide along the second straight groove 1303. When the limiting post 10 separates from the guide rod 14, the guide rod 14 will reset under the action of the torsion spring. When the limiting post 10 moves to the end of the stroke on one side of the second straight groove 1303, the glass fiber felt is completely separated from the mold 2 and the gap between it and the conveyor belt is very small. At this time, the cylinder 8 controls the connecting plate 6 to move toward the initial position, and the first spring 9 is released elastically to control the position of the ejector plate 7 to remain unchanged through the movable rod 5, so as to always provide downward pressure to the glass fiber felt. At the same time, the limiting post 10 will slide along the second straight groove 1303 again.

[0060] When the limiting post 10 moves to the position where the second straight groove 1303 and the second inclined groove 1304 are connected, the limiting post 10 abuts against the guide rod 14. Under the action of the guide rod 14, the limiting post 10 enters the second inclined groove 1304, so that the guide sleeve 12 moves toward the initial position through the movable plate 13, thereby driving the rack plate 16 to move. Under the action of the rack plate 16, the support plate 28 moves toward the opposite direction through the rotating component and the horizontal opening and closing mechanism until the limiting post 10 disengages from the second inclined groove 1304 and returns to the first straight groove 1301. At this time, the support plate 28 returns to the initial position and is no longer in contact with the glass fiber mat. Under the action of gravity, the glass fiber mat will separate from the ejector plate 7 and fall onto the conveyor belt, thereby achieving a smooth demolding effect.

[0061] Please see Figures 1-7 , Figure 9A rotating assembly is disposed on the side wall of the mold 2 and connected to the follow-up translation mechanism. The rotating assembly includes a first rotating rod 17 rotatably mounted on the mold 2, on which a gear 18 and a first bevel gear 19 are disposed. The gear 18 meshes with the rack plate 16. The assembly also includes a second rotating rod 20 and a third rotating rod 22 rotatably mounted on the mold 2. The second rotating rod 20 is connected to the third rotating rod 22 via a first belt 23. The second rotating rod 20 is provided with a second bevel gear 21 that meshes with the first bevel gear 19.

[0062] Furthermore, when the fiberglass mat needs to be ejected, the movable plate 13 is controlled to move under the action of the limiting post 10 and the guide groove, thereby controlling the movement of the rack plate 16. Under the action of the rack plate 16 and the gear 18, the first rotating rod 17 is controlled to rotate, thereby driving the first bevel gear 19 to rotate. Under the action of the first bevel gear 19 and the second bevel gear 21, the second rotating rod 20 is rotated. The second rotating rod 20 also controls the third rotating rod 22 to rotate through the first belt 23, so as to control the two support plates 28 to move toward each other through the horizontal opening and closing mechanism. Similarly, when the rack plate 16 moves toward the initial position, the two support plates 28 move toward each other.

[0063] Please see Figures 1-7 , Figure 9 , Figure 12 The rotating assembly is provided with a horizontal opening and closing mechanism, and symmetrically arranged support plates 28 are connected to the horizontal opening and closing mechanism. The rotating assembly can move when the follow-up translation mechanism moves, and the horizontal opening and closing mechanism controls the two support plates 28 to move toward or away from each other. The horizontal opening and closing mechanism includes a second spiral groove 2201 formed on the third rotating rod 22. A symmetrically arranged sliding sleeve 24 is slidably installed on the third rotating rod 22. A second limiting block 2401 is provided inside the sliding sleeve 24 and slidably engages with the second spiral groove 2201. The side wall of the sliding sleeve 24 is provided with a sliding contact with the second rotating rod 20. The guide ring 25 is connected, and the sliding sleeve 24 is provided with an elastic support assembly. The elastic support assembly includes a support sleeve 26 installed on the sliding sleeve 24, a support rod 27 slidably installed inside the support sleeve 26, the support rod 27 being connected to the support plate 28, and a movable ring 30 slidably installed on the support sleeve 26. It also includes a slot 2601 formed on the support sleeve 26, a limiting ring 2701 slidably connected to the slot 2601 on the support rod 27, and a second spring 29 sleeved on the support sleeve 26. The two ends of the second spring 29 abut against the movable ring 30 and the limiting ring 2701, respectively.

[0064] Furthermore, in the initial state, the second spring 29 is in a compressed state, controlling the support rod 27 to be at the end of its stroke toward the support sleeve 26 via the limiting ring 2701, causing the support plate 28 to tend to move toward the support sleeve 26. The second limiting block 2401 is located at the end of its stroke on one side of the second spiral groove 2201, maximizing the distance between the two sliding sleeves 24. When it is necessary to close the opening of the mold 2, the third rotating rod 22 rotates, driving the second spiral groove 2201 to move. Under the action of 1, the sliding sleeve 24 is driven to move, thereby driving the guide ring 25 to move along the length direction of the second rotating rod 20. Under the action of the guide ring 25 and the second rotating rod 20, the sliding sleeve 24 is ensured not to rotate with the third rotating rod 22 and to move along the length direction of the third rotating rod 22. The sliding sleeve 24 will also drive the support sleeve 26 to move, thereby controlling the two support plates 28 to move towards each other through the support rod 27. When the limiting post 10 disengages from the first inclined groove 1302 and enters the second straight groove 1303, the two support plates 28 will abut.

[0065] Preferably, in the initial state, the compression of the second spring 29 is greater than that of the first spring 9. Therefore, when the ejector plate 7 controls the glass fiber mat to abut against the support plate 28, under the action of the connecting plate 6, the size of the engagement between the hollow rod 4 and the movable rod 5 increases, thereby increasing the compression of the first spring 9. Before the compression of the first spring 9 exceeds the compression of the second spring 29, the ejector plate 7 will not move, so as to provide a certain compressive force to the glass fiber mat and prevent the glass fiber mat from deforming when the mold 2 rotates. When the compression of the first spring 9 is greater than that of the second spring 29, the ejector plate 7 will not move, thus providing a certain compressive force to the glass fiber mat and preventing deformation of the glass fiber mat when the mold 2 rotates. When the second spring 29 is in motion, the ejector plate 7 will drive the support plate 28 to move via the fiberglass mat, causing the support rod 27 to move away from the support sleeve 26. This compresses the second spring 29 via the limiting ring 2701. Simultaneously, when the hollow rod 4 moves, it will also drive the strength adjustment mechanism to move, ensuring that the elastic potential energy of the first spring 9 remains constant when the support plate 28 moves away from the support sleeve 26. This prevents the fiberglass mat from being damaged due to excessive compression caused by excessive compression of the first spring 9 and the second spring 29.

[0066] Please see Figures 1-9 , Figure 11 , Figure 13A strength adjustment mechanism is provided on the mold 2 and connected to the horizontal opening and closing mechanism and the ejection assembly. The ejection assembly can adjust the supporting force of the horizontal opening and closing mechanism on the support plate 28 through the strength adjustment mechanism. The strength adjustment mechanism includes a vertical groove 401 and a first spiral groove 402 formed on the outer circumference of the hollow rod 4. The ends of the vertical groove 401 and the first spiral groove 402 are connected to each other. A first limiting block 301 is provided inside the rotating sleeve 3, which slides and engages with the vertical groove 401 and the first spiral groove 402. A fourth rotating rod 32 is rotatably mounted on the mold 2. The fourth rotating rod 32 is fitted with a second belt 31 connected to the rotating sleeve 3. The fourth rotating rod 32 is provided with a lifting assembly connected to the movable ring 30. The lifting assembly includes a third spiral groove 3201 formed on the fourth rotating rod 32. The movable sleeve 33 is slidably installed on the fourth rotating rod 32. The movable sleeve 33 is provided with a third limiting block 3301 that slidably engages with the third spiral groove 3201. The movable sleeve 33 is provided with an adjusting plate 34 fitted on the support sleeve 26. The adjusting plate 34 abuts against the movable ring 30.

[0067] In the initial state, the hollow rod 4 is located at the end of its stroke away from the mold 2. At this time, the first limiting block 301 is located at the end of its stroke on the side of the vertical groove 401 away from the first spiral groove 402, and the third limiting block 3301 is located at the end of its stroke on the side of the third spiral groove 3201 away from the support plate 28, so as to minimize the distance between the adjusting plate 34 and the sliding sleeve 24. When the hollow rod 4 moves toward the mold 2, the ejector plate 7 will push the glass fiber felt toward the opening of the mold 2. The hollow rod 4 will also drive the vertical groove 401 to move, so that the first limiting block 301 slides along the vertical groove 401, ensuring that the fourth rotating rod 32 will not rotate. When the ejector plate 7 controls the glass fiber felt to abut against the support plate 28, the first limiting block 301 is still located in the vertical groove. Inside 401, when the elastic potential energy of the first spring 9 exceeds the elastic potential energy of the second spring 29, the ejector plate 7 will control the movement of the support plate 28 through the glass fiber felt. At this time, the first limiting block 301 just disengages from the vertical groove 401 and enters the first spiral groove 402, causing the rotating sleeve 3 to rotate. This, in turn, controls the rotation of the fourth rotating rod 32 through the second belt 31. Under the action of the third spiral groove 3201 and the third limiting block 3301, the regulating plate 34 moves along the length of the fourth rotating rod 32 and moves away from the sliding sleeve 24. Since the support plate 28 is also moving away from the sliding sleeve 24 at this time, the compression of the second spring 29 remains unchanged, thus ensuring that the compressive force on the glass fiber felt is not too great.

[0068] A demolding method for an aerogel felt mold demolding device includes the following steps:

[0069] Step 1: After the aerogel felt is placed in the mold 2 and formed, the ejector plate 7 can be controlled to move toward the opening of the mold 2 through the ejector assembly to eject the aerogel felt.

[0070] Step 2: The ejector component will also drive the follow-up translation mechanism to move, and control the translation opening and closing mechanism by rotating the component, so that the two support plates 28 move toward each other.

[0071] Step 3: When the side walls of the support plate 28 abut against each other, the mold 2 is sealed under the action of the support plate 28. As the ejector plate 7 continues to move, the aerogel felt is placed between the support plate 28 and the ejector plate 7.

[0072] Step 4: At this time, the opening direction of mold 2 is rotated to face the processing frame 1, and the ejector assembly continues to control the movement of ejector plate 7, so that the aerogel felt is detached from the mold. At the same time, the ejector assembly will also reduce the downward pressure of support plate 28 on aerogel felt through strength adjustment mechanism.

[0073] Step 5: When the ejector assembly controls the ejector plate 7 to move toward the initial position, the follow-up translation mechanism causes the support plate 28 to move toward directions away from each other until the aerogel felt is detached from the mold 2.

[0074] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics.
