DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, not all the embodiments.

[0026] Reference Figures 1-8 A PMMA pouring plate pressing table device with a rapid exhaust function, comprising a base 1, a support frame 2 and a turnover mechanism 3 are installed on the base 1, an exhaust mechanism 4 is installed on the support frame 2, a positioning mechanism 5 is installed on the turnover mechanism 3, a lower mold 6 and an upper mold 7 are placed on the positioning mechanism 5, a material injection port 8 is installed on the lower mold 6, the exhaust mechanism 4 comprises an air cylinder 401 installed on the support frame 2, a pressing plate 402 is installed on the output end of the air cylinder 401, two exhaust pins 403 are installed on the pressing plate 402, two cavities 404 are opened on the upper mold 7, two first springs 405 are installed in each cavity 404, a connecting block 406 is installed at the opposite end of each first spring 405, a second spring 407 is installed on the bottom wall of the cavity 404, and a floating block 408 is installed at the other end of the second spring 407.

[0027] The device indirectly flips and tilts the upper mold 7 and the lower mold 6 through the flipping mechanism 3, injects the acrylic solution into the mold through the injection port 8, and then closes the injection port 8. The upper mold 7 and the lower mold 6 are flipped to a horizontal state by the flipping mechanism 3, and then the positioning mechanism 5 is activated. The positions of the upper mold 7 and the lower mold 6 are limited by the positioning mechanism 5. Then the exhaust mechanism 4 is turned on, and the cylinder 401 operates to drive the pressing plate 402 to press down. When the pressing plate 402 is pressed down, the exhaust pin 403 first contacts the cavity 404. The exhaust pin 403 is inserted between two adjacent connecting blocks 406, so that the two adjacent connecting blocks 406 are pressed against the two ends of the protrusion on the exhaust pin 403, thereby creating a gap between the two adjacent connecting blocks 406. When the pressing plate 402 continues to press down, the two ends of the exhaust pin 403 always remain in contact with the connecting block 406. The pressing plate 402 presses the upper mold 7 downward, so that the air in the upper mold 7 and the lower mold 6 is squeezed. The acrylic solution flows into the cavity 404 and is then discharged from the gap between the two connecting blocks 406. When the air in the upper mold 7 and the lower mold 6 is completely discharged, the acrylic solution enters the cavity 404. The tension of the second spring 407 is less than the buoyancy of the acrylic solution. When the acrylic solution rises, the floating block 408 moves upward under the influence of the buoyancy of the liquid until the two ends of the floating block 408 are abutted between the two adjacent connecting blocks 406, thereby sealing the cavity 404 and preventing the acrylic solution from flowing out of the cavity 404. After the exhaust is completed, the cylinder 401 drives the exhaust pin 403 to move upward and be pulled out of the cavity 404, causing the first spring 405 to pull the connecting block 406 installed thereon to return to its original position. When the two adjacent connecting blocks 406 approach each other, the floating block 408 is squeezed downward by the connecting block 406 and pushed out from between the two adjacent connecting blocks 406, thereby completing the return of the two adjacent connecting blocks 406.

[0028] Reference Figures 2-8 In this embodiment, the flipping mechanism 3 includes a first support block 301 installed on the base 1, and a sliding groove 314 is provided on the first support block 301. A hydraulic rod 302 is installed on the side of the first support block 301 away from the sliding groove 314, and the output end of the hydraulic rod 302 is connected to the first rack 303. The first rack 303 is slidably installed on the first support block 301, and two second support blocks 304 are installed on the base 1. The two second support blocks 304 are distributed on both sides of the first support block 301, and the same rotating rod 305 is rotatably installed on the two second support blocks 304. Two first connecting frames 306 and a first gear 307 are installed on the rotating rod 305. The first gear 307 is meshed with the first rack 303. The two first connecting frames 306 are distributed on both sides of the first gear 307, and the same connecting plate 308 is installed on the two first connecting frames 306, and the lower mold 6 and the upper mold 7 are placed on the connecting plate 308.

[0029] When the turnover mechanism 3 is started, the hydraulic rod 302 is first operated, the hydraulic rod 302 pushes the first rack 303 to move along the sliding groove 314, so that the first gear 307 rotates, thereby driving the first connecting frame 306 on the rotating rod 305 to rotate, so that the connecting plate 308 rotates, and then drives the upper mold 7 and the lower mold 6 on the connecting plate 308 to rotate synchronously, so that the upper mold 7 and the lower mold 6 are in an inclined state, at this time the hydraulic rod 302 is closed, and the acrylic solution is injected into the mold from the injection port 8. The inclined state of the upper mold 7 and the lower mold 6 makes the acrylic solution quickly flow into the mold under the influence of gravity, and after the appropriate acrylic solution is injected, the hydraulic rod 302 is started again, and the telescopic rod drives the first rack 303 to pull towards the hydraulic rod 302, so that the first connecting frame 306 is flipped towards the hydraulic rod 302, thereby driving the upper mold 7 and the lower mold 6 to flip to the horizontal direction, thereby completing the injection of the acrylic solution.

[0030] With reference to Figure 4 In the embodiment, the two second supporting blocks 304 are installed with L-shaped blocks 309 on the side close to the hydraulic rod 302, and the two L-shaped blocks 309 are installed with first limiting blocks 310, the top end of the first limiting block 310 is in contact with the first connecting frame 306 in the horizontal state, so that when the connecting plate 308 is reset after being flipped, the first connecting frame 306 first contacts the first limiting block 310, and the first limiting block 310 provides support for the first connecting frame 306, thereby preventing the connecting plate 308 installed on the first connecting frame 306 from tilting.

[0031] With reference to Figure 3 , Figure 5 and Figure 8 In the embodiment, the connecting plate 308 is installed with a limiting groove 311 on the end close to the hydraulic rod 302, and the limiting groove 311 is fitted with two second limiting blocks 312, and the connecting plate 308 is installed with two third limiting blocks 313 away from the second limiting blocks 312, so that the upper mold 7 and the lower mold 6 are located between the second limiting blocks 312 and the third limiting blocks 313, so that when the connecting plate 308 is flipped, the upper mold 7 and the lower mold 6 contact the third limiting blocks 313, preventing the upper mold 7 and the lower mold 6 from falling off the connecting plate 308, and when the connecting plate 308 is reset, the second limiting blocks 312 contact the upper mold 7 and the lower mold 6, preventing the upper mold 7 and the lower mold 6 from being offset in position on the connecting plate 308 due to inertia, and the second limiting blocks 312 are slidingly installed on the connecting plate 308, so that the two second limiting blocks 312 can be moved to the two ends of the connecting plate 308, facilitating the placement of the upper mold 7 and the lower mold 6 on the connecting plate 308 from the side of the second limiting blocks 312.

[0032] With reference to Figure 6In the embodiment, the air inlet hole 409 and the air outlet hole 410 are arranged on each cavity 404, and the air inlet hole 409 and the air outlet hole 410 are communicated with the cavity 404, so that the acrylic solution and the air between the upper die 7 and the lower die 6 can enter the cavity 404 through the air inlet hole 409, and the air is discharged from the mold through the air outlet hole 410, thereby achieving the purpose of air exhaust.

[0033] With reference to Figure 6 In the embodiment, the moving groove 411 is arranged on the upper wall of each cavity 404, and the moving strip 412 is arranged on each two adjacent connecting blocks 406, and the moving strip 412 is matched with the moving groove 411, so that when the connecting block 406 moves, the moving strip 412 moves synchronously on the moving groove 411, and the moving strip 412 always contacts with the upper wall of the cavity 404 when moving, so that the acrylic solution cannot flow out of the mold from the gap between the connecting block 406 and the cavity 404 in the non-air exhaust state, thereby ensuring the sealing property of the cavity 404.

[0034] With reference to Figure 7 In the embodiment, the sealing strip 413 is arranged on each two adjacent connecting blocks 406, and the two adjacent sealing strips 413 are staggered, so that when the two adjacent connecting blocks 406 move to the minimum distance, the two sealing strips 413 are driven to move close to each other, and the two sealing strips 413 partially overlap, thereby covering the distance between the two adjacent connecting blocks 406, so as to prevent the acrylic solution from flowing out of the mold from the gap between the two adjacent connecting blocks 406 in the non-air exhaust state, and further ensure the sealing property of the cavity 404.

[0035] With reference to Figures 2-5 In the embodiment, the positioning mechanism 5 comprises a second connecting frame 501 arranged on the lower wall of the connecting plate 308, a servo motor 502 is arranged on the lower wall of the second connecting frame 501, the output end of the servo motor 502 penetrates through the second connecting frame 501 and is connected with a second gear 503, one end of the second gear 503 away from the servo motor 502 is rotatably arranged on the lower wall of the connecting plate 308, and the two ends of the second gear 503 are respectively engaged with a second rack 504 and a third rack 505, and one end of the second rack 504 and the third rack 505 away from each other is respectively connected with a first connecting strip 506 and a second connecting strip 507, and the first connecting strip 506 and the second connecting strip 507 are respectively connected with a first positioning plate 508 and a second positioning plate 509.

[0036] When the positioning mechanism 5 is enabled, first, the servo motor 502 is started, and when the servo motor 502 rotates clockwise, the second gear 503 is driven to rotate clockwise, so that the second rack 504 and the third rack 505 are moved away from each other at one end to the center of the second gear 503, so that the first positioning plate 508 and the second positioning plate 509 are moved to the center of the device, and when they are in the appropriate position, they are in contact with the mold, thereby clamping the mold, and the position of the upper mold 7 and the lower mold 6 is limited, and the servo motor 502 rotates counterclockwise, so that the first positioning plate 508 and the second positioning plate 509 move away from the second gear 503, thereby releasing the limitation of the mold.

[0037] With reference to Figure 5 In the embodiment, two grooves 510 are formed on the lower wall surface of the connecting plate 308, and the second rack 504, the third rack 505, the first connecting strip 506 and the second connecting strip 507 are each provided with a moving block 511 at one end close to the connecting plate 308, and the moving block 511 and the groove 510 are matched, so that the second rack 504 and the third rack 505 can be slidably installed on the connecting plate 308 through the matching of the moving block 511 and the groove 510, thereby providing the second rack 504 and the third rack 505 with tension through the connecting plate 308, preventing the second rack 504 and the third rack 505 from falling off.

[0038] With reference to Figure 2 In the embodiment, two positioning grooves 512 are formed on the connecting plate 308, and the positions of the two positioning grooves 512 correspond to the first positioning plate 508 and the second positioning plate 509 respectively, so that the first positioning plate 508 and the second positioning plate 509 can extend out of the connecting plate 308 through the two positioning grooves 512, thereby positioning the mold through the movement of the first positioning plate 508 and the second positioning plate 509.

[0039] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto, and any person skilled in the art can make equivalent replacement or change according to the technical solution and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
