Description

Technical Field

[0001] This invention belongs to the field of mold technology, and specifically discloses a hot pressing mold for arc-shaped bamboo composite materials. Background Technology

[0002] The curved bamboo laminated timber hot-press forming mold is the core equipment for processing curved bamboo materials, and its core structure consists of upper and lower curved modules. The working surfaces of the upper and lower molds are matched with an arc shape, and a U-shaped steam pipe is built in. When pressing curved bamboo laminated timber, the raw bamboo needs to be cut into bamboo tubes of a certain length. Then, the bamboo tubes are longitudinally widened or split using a circular saw or a split saw to make curved bamboo veneers. After the curved bamboo veneers are placed into the hot-press forming mold, the mold is heated and softened, and the upper and lower molds are pressed by a veneer press. Finally, the bamboo veneers are glued together to form curved bamboo laminated timber.

[0003] The size of the hot pressing molds in the existing technology is not adjustable, and multiple molds cannot be spliced ​​together to complete the hot pressing of long curved bamboo veneers. As a result, when a longer piece of timber needs to be hot-pressed, a longer mold needs to be replaced.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0031] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0032] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may be practiced in other ways different from those described herein, and therefore the invention is not limited to the specific embodiments disclosed below.

[0033] like Figures 1-12 The illustrated arc-shaped bamboo laminated timber hot-pressing mold includes two mounting plates 1. An upper mold 2 and a lower mold 3 are bolted to one side of each mounting plate 1. The upper mold 2 and the lower mold 3 are used for hot-pressing bamboo veneers. Both the upper mold 2 and the lower mold 3 are equipped with mold splicing mechanisms 4 on their exteriors. The mold splicing mechanisms 4 are used to splice the upper mold 2 and the lower mold 3. A top connecting mechanism 5 is provided on the top of the mounting plate 1. A top splicing mechanism 6 is provided on the top of the top connecting mechanism 5. The top connecting mechanism 5 is used to connect the mounting plate 1 and the top splicing mechanism 6. A heating mechanism 7 is provided inside the upper mold 2. The heating mechanism 7 is used to introduce steam to heat the upper mold 2, thereby facilitating the hot pressing of the bamboo veneers.

[0034] The mold assembly mechanism 4 includes a fixing plate 401, which provides installation space. Two fixing plates 401 are fixedly connected to the outside of the upper mold 2 and the lower mold 3, respectively. A torsion spring 402 is installed inside the fixing plate 401. A connecting hollow column 403 is rotatably connected to the middle of the fixing plate 401. A rotating cap 404 is fixedly connected to one end of the connecting hollow column 403. The torsion spring 402 can exert a force on the connecting hollow column 403 using its own reaction force, thereby preventing the rotating cap 404 from rotating. Fixing columns 405 are fixedly connected to the outside of the upper mold 2 and the lower mold 3, providing installation positions. A fixing box 406 is fixedly connected to the outside of the fixing column 405, providing installation positions. The fixing box 406 has a set of internal components. A limit plate 408 is slidably connected inside the push spring 407 and the fixed box 406. The limit plate 408 has a limiting function. A push head 409 is fixedly connected to the end of the limit plate 408 away from the push spring 407. A spring piece 410 is fixedly connected inside the rotating cap 404. The push head 409 can push the spring piece 410 to bend. A locking head 411 is fixedly connected to the side of the spring piece 410 away from the push head 409. A splicing rod 412 is provided inside one side of both the upper mold 2 and the lower mold 3. A limit cap 413 is fixedly connected to one end of the splicing rod 412. A locking groove 414 is opened on the outside of the other end of the splicing rod 412. The locking head 411 can be inserted into the locking groove 414, thereby preventing the splicing rod 412 from being pulled out of the upper mold 2 or the lower mold 3. Inside mold 3, multiple inserts 416 are fixedly connected to one side of upper mold 2 and lower mold 3. Each insert 416 has a splicing hole 417. Slots 418 are provided on the side of upper mold 2 and lower mold 3 away from the inserts 416. Inserts 416 are inserted into slots 418, allowing splicing of upper mold 2 or lower mold 3. One end of torsion spring 402 is fixedly connected to the inside of fixed plate 401, and the other end is fixedly connected to the outside of connecting hollow column 403. An anti-rotation groove 415 is provided on the outside of rotating cap 404. One end of push spring 407 is fixedly connected to the inside of fixed box 406, and the other end is fixedly connected to the side of limit plate 408 away from push head 409, allowing for multiple upper and lower molds to be spliced. When assembling mold 2 and lower mold 3, firstly, rotate the rotating cap 404. The rotating cap 404 drives the connecting hollow column 403 to rotate, compressing the torsion spring 402. Simultaneously, as the rotating cap 404 rotates, the side of the pushing head 409 closest to it is curved, providing a pushing force towards the fixed box 406. This forces the pushing head 409 out of the rotating cap 404, and also causes the limiting plate 408 to compress the pushing spring 407, rotating the anti-rotation groove 415 to the pushing head 409, causing the pushing head 409 to engage with the anti-rotation groove 415, thus preventing the rotating cap 404 from rotating. After the pushing head 409 moves out of the rotating cap 404...Under the elastic action of the spring piece 410, the locking head 411 is reset, thereby releasing the locking head 411 from the locking groove 414. At this time, the limit cap 413 can be pulled to move the splicing rod 412 out of the upper mold 2 or lower mold 3. Then, the insert post 416 on the upper mold 2 or lower mold 3 to be spliced ​​is inserted into the slot 418. Then, the splicing rod 412 is reinserted into the upper mold 2 or lower mold 3. At this time, the splicing hole 417 on the insert post 416 to be spliced ​​is inserted by the splicing rod 412. When the locking groove 414 on the splicing rod 412 is inserted into the rotating cap 40... After the inside of 4, rotate the rotating cap 404 again. The rotation of the rotating cap 404 forces the push head 409 out of the anti-rotation groove 415 and rotates the spring piece 410 on the rotating cap 404 to the push head 409. At this time, under the reaction force of the push spring 407, the spring piece 410 is pushed, causing it to deform and drive the locking head 411 to insert into the inside of the rotating cap 404. This allows the locking head 411 to insert into the locking groove 414, thus preventing the splicing rod 412 from being pulled out of the upper mold 2 or lower mold 3. At this point, the splicing of the upper mold 2 or lower mold 3 is complete.

[0035] The top connecting mechanism 5 includes a top connecting post 501, the bottom of which is fixedly connected to the top of the mounting plate 1. An insertion hole 502 is provided inside the top connecting post 501. A top connecting sleeve 503 is fitted over the top connecting post 501. The top connecting sleeve 503 can be fitted over the top connecting post 501. A pin 504 is provided inside the top connecting sleeve 503, which can be inserted into the top connecting sleeve 503 and the insertion hole 502, thereby completing the assembly of the top connecting sleeve 503 and the top connecting post 501. A beveled cap 505 is fixedly connected to one end of the pin 504, and an annular groove 50 is provided at the other end of the pin 504. 6. The end of the pin 504 furthest from the beveled cap 505 has an entry groove 507. A fixing cylinder 508 is fixedly connected to the outside of the top connecting sleeve 503, providing an installation position. A return spring 509 is installed inside the fixing cylinder 508. A limiting plate 510 is slidably connected inside the fixing cylinder 508, serving a limiting function. A locking post 511 is fixedly connected to the side of the limiting plate 510 furthest from the return spring 509. After the locking post 511 engages inside the annular groove 506, it prevents the pin 504 from sliding out of the top connecting sleeve 503 and the insertion hole 502. The bottom of the locking post 511 engages with the inside of the annular groove 506. The return spring... One end of spring 509 is fixedly connected to the side of the limiting plate 510 away from the locking post 511, and the other end of spring 509 is fixedly connected to the inside of the fixing cylinder 508. When hot pressing of bamboo veneer is required, first rotate the bevel cap 505. Since the side of the bevel cap 505 near the top connecting sleeve 503 is concave with two longer sides and two shorter sides, when rotating the bevel cap 505, the longer side of the bevel cap 505 rotates from horizontal to vertical, which will drive the pin 504 to move in the direction of the bevel cap 505, and drive the locking post 511 and the limiting plate 510 to move into the inside of the fixing cylinder 508, and use the limiting plate 510 to compress the return spring 509. When entering the groove 5 When the pin 504 is rotated to the position of the locking pin 511, it can be pulled out of the top connecting sleeve 503. At this time, the top connecting sleeve 503 can be fitted onto the outside of the top connecting pin 501, and the pin 504 can be inserted into the insertion hole 502 on the top connecting pin 501 again. The locking pin 511 is slid into the annular locking groove 506 by the entry groove 507. At this time, under the action of the return spring 509, the limiting plate 510 and the locking pin 511 can be pushed to move outward. Since the bevel cap 505 is grooved, the edge of the groove will be in close contact with the outside of the top connecting sleeve 503, and under the action of the locking pin 511, the bevel cap 505 can be prevented from rotating.

[0036] The top splicing mechanism 6 includes splicing columns 601, which are capable of splicing. Two bottom connecting columns 602 are fixedly connected to the bottom of the splicing column 601, providing an installation position. A connector 603 is fixedly connected to the bottom of each bottom connecting column 602. A sliding sleeve 604 is slidably connected to the outside of each bottom connecting column 602. A thrust spring 605 is sleeved on the outside of each bottom connecting column 602, pushing the sliding sleeve 604 downwards. A threaded connector 606 is fixedly connected to one end of the splicing column 601, and a threaded groove 607 is formed inside the other end of the splicing column 601. The splicing column 601 is installed by screwing the threaded connector 606 into the threaded groove 607. A second connector 608 is fixedly connected to the top of the top connecting sleeve 503. After the second connector 608 engages with the first connector 603, the sliding sleeve 604 slides into the second connector. The splicing point of connector 608 and connector 603 allows for the splicing of connector 603 and connector 608. Connector 608 engages with threaded groove 607. One end of thrust spring 605 is fixedly connected to the top of sliding sleeve 604, and the other end is fixedly connected to the bottom of splicing post 601. First, sliding sleeve 604 is pushed upward, which compresses thrust spring 605, exposing connector 603 and engaging connector 603 with connector 608. Then, sliding sleeve 604 is released, and under the push of thrust spring 605, sliding sleeve 604 moves downward and fits over connector 603 and connector 608. This completes the splicing of bottom connecting post 602 and top connecting sleeve 503, allowing top connecting mechanism 5 to be installed on top splicing mechanism 6, and finally, installation of mounting plate 1.

[0037] The heating mechanism 7 includes a steam inlet pipe 701, which provides a path for steam to enter and transfers heat to the upper mold 2 via thermal conduction. The exterior of the steam inlet pipe 701 is located inside the upper mold 2. A retaining ring 702 is fixedly connected to one end of the steam inlet pipe 701, providing an installation position. A splicing insert pipe 705 is fixedly connected to the other end of the steam inlet pipe 701. A retaining spring 703 is located at one end of the retaining ring 702. A sliding sealing sleeve 704 is slidably connected inside the steam inlet pipe 701. The retaining spring 703 exerts its own reaction force on the sliding sealing sleeve 704, causing the sliding sealing sleeve 704 to press tightly against the splicing insert pipe 705. The upper mold 2 and the lower mold 3 are spliced ​​together with the upper mold 2 and the lower mold 3. The splicing tube 705 on the upper mold 2 can be inserted into the steam inlet tube 701 on the upper mold 2 to be spliced. After the splicing tube 705 is inserted, it can contact the sliding sealing sleeve 704 and compress the upper mold 703. The reaction force of the upper mold 703 can make the sliding sealing sleeve 704 stick tightly to the end of the splicing tube 705, thereby improving the sealing performance and allowing steam to smoothly enter the interior of the spliced ​​steam inlet tube 701.

[0038] Working principle: When assembling multiple upper molds 2 and lower molds 3, firstly, the rotating cap 404 is rotated. The rotating cap 404 drives the connecting hollow column 403 to rotate, compressing the torsion spring 402. Simultaneously, as the rotating cap 404 rotates, because the side of the pushing head 409 closest to the rotating cap 404 is curved, rotating the rotating cap 404 provides a pushing force to the fixed box 406, thereby squeezing the pushing head 409 out of the rotating cap 404 and causing it to... The moving limit plate 408 compresses the push spring 407 and rotates the anti-rotation groove 415 to the push head 409, causing the push head 409 to engage with the anti-rotation groove 415, thereby preventing the rotating cap 404 from rotating. After the push head 409 moves out of the interior of the rotating cap 404, the elastic action of the spring piece 410 drives the locking head 411 to reset, thereby releasing the locking head 411 from the locking groove 414. At this time, the limit cap 413 can be pulled and the splicing rod 412 can be moved out of the upper mold 2 or the lower mold 2. Inside mold 3, insert the pin 416 on the upper mold 2 or lower mold 3 to be spliced ​​into the slot 418. Then, re-insert the splicing rod 412 into the upper mold 2 or lower mold 3. At this time, the splicing hole 417 on the insert pin 416 to be spliced ​​is inserted into the splicing rod 412. After the engaging groove 414 on the splicing rod 412 is inserted into the rotating cap 404, rotate the rotating cap 404 again. After the rotating cap 404 rotates, it can push the push head 409 out of the anti-rotation groove 415. Inside the rotating cap 404, the spring piece 410 on the rotating cap 404 is rotated to the push head 409. At this time, under the reaction force of the push spring 407, the spring piece 410 can be pushed to deform the spring piece 410 and drive the clip head 411 to be inserted into the rotating cap 404. The clip head 411 is inserted into the locking groove 414, which can prevent the splicing rod 412 from being pulled out of the upper mold 2 or the lower mold 3. At this time, the splicing of the upper mold 2 or the lower mold 3 can be completed, which facilitates the hot pressing of long bamboo veneers.

[0039] When hot pressing bamboo veneer is required, first rotate the bevel cap 505. Since the bevel cap 505 has a concave shape with two longer sides and two shorter sides near the top connecting sleeve 503, rotating the bevel cap 505 causes its longer side to rotate from horizontal to vertical. This moves the pin 504 towards the bevel cap 505, and causes the locking post 511 and the limiting plate 510 to move into the fixed cylinder 508. The limiting plate 510 then compresses the return spring 509. When the slot 507 rotates to the locking post 511, the pin 504 can be pulled out of the top connecting sleeve 503. Inside the sleeve 503, the top connecting sleeve 503 can be fitted onto the outside of the top connecting post 501, and the pin 504 can be inserted into the insertion hole 502 on the top connecting post 501 again. The locking post 511 is slid into the annular locking groove 506 using the inlet groove 507. At this time, under the action of the return spring 509, the limiting plate 510 and the locking post 511 can be pushed to move outward. Since the beveled cap 505 is grooved, the edge of the groove will be in close contact with the outside of the top connecting sleeve 503, and under the pushing force of the locking post 511, the beveled cap 505 can be prevented from rotating.

[0040] First, push the sliding sleeve 604 upward, which will compress the thrust spring 605, exposing the first connector 603 and engaging it with the second connector 608. Then, release the sliding sleeve 604, which will then move downward under the push of the thrust spring 605 and fit over the outside of the first connector 603 and the second connector 608. This completes the splicing of the bottom connecting post 602 and the top connecting sleeve 503. Then, the top connecting mechanism 5 can be installed on the top splicing mechanism 6, and the installation of the mounting plate 1 can be completed.

[0041] When the upper mold 2 and lower mold 3 are spliced ​​together with the spliced ​​upper mold 2 and lower mold 3, the splicing tube 705 on the upper mold 2 can be inserted into the steam inlet tube 701 on the upper mold 2 to be spliced. After the splicing tube 705 is inserted, it can contact the sliding sealing sleeve 704 and compress the clamping spring 703. The reaction force of the clamping spring 703 can make the sliding sealing sleeve 704 stick tightly to the end of the splicing tube 705, thereby improving the sealing performance and allowing steam to smoothly enter the interior of the spliced ​​steam inlet tube 701.
