Most of the existing PVC anti-collision plates are produced by hot pressing;

[0003] After the equipment has been hot-pressed for multiple times, it is very easy for some debris that has not been completely removed or has fallen from the formed anti-collision plate to remain in the mold cavity. If the debris in the cavity is not cleaned in time, it will continue to accumulate in the cavity for a long time. During the subsequent multiple hot pressings, the remaining debris will be pressed tightly in the cavity and difficult to clean.

[0018] The present invention has the beneficial effects:

[0019] 1. The present invention uses a hard brush to perform hard friction cleaning on the inner wall of the cavity of the lower mold as the extended corrugated sheet rotates, so as to prevent the debris accumulated in the cavity from being tightly pressed to the inner wall of the cavity and difficult to clean during the subsequent multiple hot pressings. When the circular empty shell moves upward, the formed anti-collision plate is pushed to gradually move up to the top of the lower mold, so as to prevent the high temperature of the anti-collision plate after hot pressing from making it difficult for the staff to quickly unload it from the cavity and affect the production efficiency. The annular arc sheet scrapes and cleans the outer side surface of the moving circular empty shell, so as to prevent the outer side surface of the circular empty shell from being attached with residual debris from cleaning and affecting the blocking of the second circular hole.

[0020] 2. The present invention provides a chip cleaning mechanism, and a circular through rod passing through the second circular plate performs a through rotation limit on it, so as to prevent the second circular plate from being easily offset and misaligned due to uneven force when rotating with the downward pressure spring. The hard brush performs hard friction cleaning on the inner wall of the cavity of the lower mold as the extended corrugated sheet rotates, so as to prevent the debris accumulated in the cavity from being tightly pressed to the inner wall of the cavity and being difficult to clean during subsequent multiple hot pressings. By providing a corrugated sheet with a plastic rebound effect, it is convenient for the corrugated sheet to shrink in the range covered above the bottom circular plate, so as to prevent the range covered by the corrugated sheet after extension from exceeding the range covered by the bottom circular plate, which makes it difficult for the corrugated sheet to pass through the first circular hole. The bottom circular plate performs contact-type cleaning on the moving hard brush, so as to prevent the dense hard brush from being mixed with too many debris and other debris after long-term use, affecting the subsequent cleaning efficiency.

[0021] 3. The present invention provides a material pushing mechanism, and when the circular empty shell moves upward, it pushes the formed anti-collision plate and pushes it to gradually move up to the top of the lower mold, so as to prevent the high temperature of the anti-collision plate after hot pressing molding, which may make it difficult for the staff to quickly unload it from the cavity and affect the production efficiency. By providing a cooling rod, the gas is sprayed from the ventilation hole after cooling to quickly cool down the high-temperature formed anti-collision plate, so as to prevent the formed anti-collision plate from having a slow natural cooling speed, which may make it difficult to manually unload it during subsequent unloading and easy to deform during the unloading process. The extended corrugated ring sheet surrounds and covers the interior of the circular empty shell, and prevents small pieces of debris in the cavity of the lower mold from infiltrating into the circular empty shell through the ventilation hole in large quantities and accumulating and being difficult to handle. When the inner sliding circular plate moves up, it drives some debris infiltrated into the outer side of the corrugated ring sheet and the area above the inner sliding circular plate to move up together and overflow to the outside through the ventilation hole, so as to prevent some debris from infiltrating into the area outside the corrugated ring sheet and the area above the inner sliding circular plate through the ventilation hole, which is difficult to handle and affects the expansion and contraction of the corrugated ring sheet.

[0022] 4. The present invention provides a cleaning component, and the annular arc sheet scrapes and cleans the outer side surface of the moving circular empty shell to prevent the residual debris attached to the outer side surface of the circular empty shell from affecting the sealing of the second circular hole. The arc-shaped barbed strips on the inner side of the annular arc sheet intermittently penetrate into the ventilation circular hole on the surface of the circular empty shell to prevent the accumulation of some debris in the ventilation circular hole after a long period of cleaning to block it and affect its ventilation effect. An outer oblique ring plate is provided on the outer side of the long connecting rod to block the fallen debris, and a large amount of fallen debris is prevented from being concentrated on the receiving plate and being difficult to handle and finally being sucked into the interior by the high-pressure air pump. A retractable corrugated connecting piece is provided between the outer oblique ring plate and the annular arc sheet to cover the inner area of ​​the outer oblique ring plate, and a part of the large amount of debris falling downward is prevented from passing through the inner side of the outer oblique ring plate and falling on the receiving plate.

Two ejection mechanisms 6 are provided, and the two ejection mechanisms 6 are evenly distributed at the bottom of the lower mold 1;

[0039] Wherein, the chip cleaning mechanism 5 comprises:

[0040] A hard brush 501, which is used to perform hard friction cleaning on the inner wall of the cavity of the lower mold 1;

[0042] The top of the hydraulic push rod 4 is fixedly connected to the inner side of the curved connecting plate 7, and two second circular holes 9 are provided, and the two second circular holes 9 are evenly distributed at the bottom of the lower mold 1;

[0043] The chip cleaning mechanism 5 also includes a first concave plate 502, an inner side of the first concave plate 502 is fixedly connected to a motor 503, a driving shaft of the motor 503 is fixedly connected to a first circular plate 504, a bottom of the first circular plate 504 is fixedly connected to a downward pressure spring 505, a bottom of the downward pressure spring 505 is fixedly connected to a second circular plate 506, a top of the second circular plate 506 is penetrated and slidably connected to a circular through rod 507, a bottom of the second circular plate 506 is fixedly connected to a bottom connecting rod 508, a bottom of the bottom connecting rod 508 is fixedly connected to a bottom circular plate 509, and a corrugated sheet 510 is fixedly connected to the outer side of the bottom connecting rod 508;

[0044] The bottom of the first concave plate 502 is fixedly connected to the top of the upper mold 3, the top of the circular penetration rod 507 is fixedly connected to the bottom of the first circular plate 504, the outer side of the corrugated sheet 510 is fixedly connected to one end of the hard brush 501, three corrugated sheets 510 are provided, and the three corrugated sheets 510 are evenly distributed on the outside of the bottom connecting rod 508, multiple hard brushes 501 are provided, and multiple hard brushes 501 are evenly distributed on the outside of the corrugated sheet 510. When in use, the heated molding material is inserted into the concave splint 2 for fixing, and then the upper mold 3 is pushed downward by the hydraulic push rod 4 to perform hot pressing molding on the molding material. The raw material is hot pressed in the mold cavity of the lower mold 1 for molding. After molding, the part of the raw material covered by the concave splint 2 is aligned with the lower The part in the mold 1 is cut and separated. After separation, the molded anti-collision plate can be ejected from the bottom of the lower mold 1 through the ejection mechanism 6. When the molded anti-collision plate is completely ejected from the lower mold 1, it can be taken down. When there is no molding material in the lower mold 1, the hydraulic push rod 4 can push the chip cleaning mechanism 5 to move downward as a whole until the bottom of the chip cleaning mechanism 5 contacts the bottom of the cavity of the lower mold 1. At this time, the chip cleaning mechanism 5 can be used to clean the debris pressed in the cavity of the lower mold 1. After cleaning, the hydraulic push rod 4 can be used to adjust the chip cleaning mechanism 5 upward to move a certain distance, so that the ejection mechanism 6 enters the cavity of the lower mold 1 to blow the cleaned debris, and then cooperates with the fanning of the chip cleaning mechanism 5 to clean the debris out of the cavity. After cleaning, the next step can be carried out During hot pressing, the chip cleaning mechanism 5 is adjusted by the hydraulic push rod 4 to move down as a whole to the bottom of the bottom circular plate 509 and contact the bottom of the inner wall of the cavity of the lower mold 1.

The circular penetration rod 507 that penetrates the second circular plate 506 is subjected to a through-type rotation limit. The rotation of the second circular plate 506 drives the bottom bottom connecting rod 508 to rotate. When the bottom connecting rod 508 rotates, it drives the outer corrugated sheet 510 and the bottom circular plate 509 at the bottom to rotate together.

When the corrugated sheet 510 stretches, it drives the hard brush 501 on the outside to move together. As the stretched corrugated sheet 510 rotates, the hard brush 501 performs hard friction cleaning on the inner wall of the cavity of the lower mold 1. After cleaning, the motor 503 is turned off. At this time, the corrugated sheet 510 loses the centrifugal force of high-speed rotation and performs corrugated contraction in the direction of the bottom connecting rod 508. By setting the corrugated sheet 510 with a plastic rebound effect, it is convenient for the corrugated sheet 510 to perform corrugated contraction in the range covered above the bottom circular plate 509. When the corrugated sheet 510 performs corrugated contraction, it drives the hard brush 501 on the outside to move in the direction of the bottom connecting rod 508. When the hard brush 501 moves in the direction of the bottom connecting rod 508, it contacts the outer side of the bottom circular plate 509 in turn.The bottom circular plate 509 performs contact-type cleaning on the moving hard brush 501.

The chip cleaning mechanism 5 is adjusted by the hydraulic push rod 4 to move down as a whole until the bottom of the bottom circular plate 509 contacts the bottom of the inner wall of the cavity of the lower mold 1. At this time, the motor 503 can be started to drive the first circular plate 504 to rotate. The rotation of the first circular plate 504 drives the bottom pressure spring 505 and the circular penetration rod 507 to rotate. The rotation of the circular penetration rod 507 drives the second circular plate 506 sleeved on the outside to rotate, and the second circular plate 506 is penetrated by the second circular plate 506. The circular through rod 507 is used to limit the rotation of the through-type, and the rotation of the second circular plate 506 drives the bottom connecting rod 508 to rotate. When the bottom connecting rod 508 rotates, it drives the outer corrugated sheet 510 and the bottom circular plate 509 to rotate together. As the bottom connecting rod 508 rotates, the corrugated sheet 510 is gradually stretched outward to a flat state under the action of centrifugal force. When the corrugated sheet 510 stretches, it drives the outer hard brush 501 to move together. As the stretched corrugated sheet 510 rotates, the hard brush 501 performs hard friction cleaning on the inner wall of the cavity of the lower mold 1. After cleaning, the motor 503 is turned off. At this time, the corrugated sheet 510 loses the centrifugal force of high-speed rotation and shrinks in a corrugated shape toward the bottom connecting rod 508. By setting the corrugated sheet 51 with a plastic rebound effect 0 is convenient for the corrugated sheet 510 to perform corrugated contraction within the range covered above the bottom circular plate 509. When the corrugated sheet 510 performs corrugated contraction, it drives the hard brush 501 on the outside to move toward the bottom connecting rod 508. When the hard brush 501 moves toward the bottom connecting rod 508, it contacts the outside of the bottom circular plate 509 in turn. The bottom circular plate 509 performs contact-type toggling cleaning on the moving hard brush 501. After the raw material is hot-pressed, the receiving plate 603 is pushed upward by the electric push rod 602 to move. The receiving plate 603 moves upward to drive the long connecting rod 604 on the top to move upward. The long connecting rod 604 moves upward to drive the circular empty shell 606 on the top to move upward. When the circular empty shell 606 moves upward, it punches the formed anti-collision plate and pushes it to gradually move upward to the top of the lower mold 1.When the circular hollow shell 606 gradually moves up to the outer ventilation hole 607 located in the cavity of the lower mold 1, the high-pressure air pump 609 can be started to spray the cooling rod 613 in the circular hollow shell 606 through the bottom air pipe 608. The cooling rod 613 is blown by the high-pressure gas to drive the inner smooth circular plate 611 on the top to move up. When the inner smooth circular plate 611 moves up, it pushes and compresses the corrugated ring sheet 612 and the extension spring 610 on the top. When the inner smooth circular plate 611 and the cooling rod 613 gradually move up, the gas at the bottom of the inner smooth circular plate 611 will be ejected outward through the ventilation hole 607 in turn. A cooling rod 613 is provided so that the gas is cooled and then ejected from the vent hole 607 to quickly cool down the high-temperature formed anti-collision plate. When the formed anti-collision plate is pushed to the top of the lower mold 1, the high-pressure air pump 609 can be turned off. At this time, the inner smooth circular plate 611 loses its blowing power, and the extension spring 610 at the top pushes the inner smooth circular plate 611 downward through the extension force. When the inner smooth circular plate 611 moves downward, it drives the top corrugated ring piece 612 to stretch. The stretched corrugated ring piece 612 surrounds and covers the inside of the circular shell 606. At the same time, when the inner smooth circular plate 611 moves upward, it drives the outer corrugated ring piece 612 to move upward. Some debris that infiltrated into the area above the inner smooth circular plate 611 moves upward together and overflows to the outside through the ventilation circular hole 607. After the formed anti-collision plate is successfully unloaded and removed, the circular empty shell 606 can be driven by the electric push rod 602 to move down to the top surface and be flush with the bottom surface of the inner wall of the cavity of the lower mold 1. When the circular empty shell 606 moves down and passes through the second circular hole 9, the outer side contacts the cleaning component 605 and is scraped and cleaned. When the circular empty shell 606 moves down and passes through the second circular hole 9, the outer side contacts the annular arc sheet 6051 at all times, and the annular arc sheet 6051 scrapes the outer side of the moving circular empty shell 606 At the same time, the arc-shaped barbed strip 6052 on the inner side of the annular arc piece 6051 intermittently penetrates into the vent hole 607 on the surface of the circular shell 606. The debris cleaned by the annular arc piece 6051 and the arc-shaped barbed strip 6052 accumulates on the inner side of the annular arc piece 6051 and overflows and falls outward through the arc surface hole 6053. The falling debris is blocked by setting an outer oblique ring plate 6055 on the outer side of the long connecting rod 604, and the inner area of ​​the outer oblique ring plate 6055 is covered by setting a retractable corrugated connecting piece 6054 between the outer oblique ring plate 6055 and the annular arc piece 6051.
