[0035] like Figure 1 , Figure 2 and Figure 6 As shown, the wiping mechanism 4 includes a guide rod 41, a sliding member 42, a wiping member 43 and a reciprocating threaded tube 44. The guide rod 41 is slidably connected to the left part of the sliding frame 33, the sliding member 42 is connected to the upper part of the guide rod 41, the wiping member 43 is connected between the left and right sides of the sliding member 42, the wiping member 43 is made of soft material, the outer ring of the rotating member 36 is connected to the reciprocating threaded tube 44, and the reciprocating threaded tube 44 is threadedly connected to the sliding member 42.

[0036] The injection molding machine injection mold that is easy to exhaust is used to make a plastic honeycomb grille. When in use, the upper mold 1 needs to be moved upward first to remove the upper mold 1. At this time, the cavity of the lower mold 2 is exposed, and then it is necessary to ensure that the flip cover 22 is in an unopened state and the first spring 23 is in a state of neither stretching nor compression. Then, plastic is injected into the cavity through the injection molding machine. Because the air permeable member 21 is made of special material, only gas can penetrate and pass through the air permeable member 21, and plastic cannot pass through the air permeable member 21, so the air permeable member 21 will not affect the plastic molding. Then, the exhaust pipe 24 is connected to the external air pump, and the upper mold 1 is covered back on the top of the lower mold 2 to make the cavity sealed. The lower side of the lower mold 2 is plugged with cloth to prevent air leakage, and then the external air pump is started. The gas in the plastic is sucked out and discharged through the exhaust pipe 24 and the breathable member 21, so that there are no residual bubbles in the plastic, which can improve the quality of the obtained plastic honeycomb grille, and then the external air pump is turned off, and the plastic honeycomb grille is solidified after a series of processing, and then the upper mold 1 is moved upward again, so as to remove the upper mold 1, remove the plastic honeycomb grille, remove the external air pump, remove the cloth, and then turn the one-way screw 32 by hand, so that the one-way screw 32 drives the sliding frame 33 to move upward, so that the waterproof motor 34, the first straight gear 35, the rotating member 36, the telescopic member 37 and the second spring 38 are all moved upward, and at the same time, the guide rod 41, the sliding member 42, the wiping member 43 and the reciprocating threaded tube 44 are all moved upward, so that the telescopic member 37 The telescopic member 37 contacts the breathable member 21, and as the rotating member 36 continues to move upward, the lower part of the telescopic member 37 is retracted into a point in the rotating member 36, and the second spring 38 is compressed, so that the telescopic member 37 further presses the breathable member 21, and then the waterproof motor 34 is started. Driven by the output shaft of the waterproof motor 34, the adjacent first spur gear 35 rotates, so that the other first spur gear 35 drives the rotating member 36 to rotate, and the rotating member 36 drives the telescopic member 37 and the second spring 38 to rotate. In this way, the telescopic member 37 can scrape off impurities on the lower side of the breathable member 21, so that the impurities adhere to the telescopic member 37 to avoid blockage. Because the upper part of the telescopic member 37 is provided with an inclined surface, it is more conducive to the telescopic member 37 to scrape off impurities. At the same time as the rotating member 36 rotates When the wiper 43 is moved upward and downward, the wiper 43 and the guide rod 41 are moved upward and downward, and the wiper 43 is able to wipe off the impurities on the inner wall of the lower mold 2, so that these impurities adhere to the wiper 43, thereby avoiding blockage. After cleaning, the waterproof motor 34 is turned off, and the one-way screw 32 is rotated in the opposite direction by hand, so that the one-way screw 32 drives the sliding frame 33 to move downward, thereby making the waterproof motor 34, the first straight gear 35, and the rotating member 36 move downward, and at the same time, the guide rod 41, the sliding member 42, the wiper 43 and the reciprocating threaded tube 44 move downward, so that the second spring 38 will stretch and recover first,Then the second spring 38 and the telescopic member 37 will move downward and reset together with the rotating member 36, and then the upper mold 1 will be placed back on the lower mold 2, and the telescopic member 37 and the wiping member 43 will be cleaned. The air-permeable member 21 and the lower mold 2 are cleaned by the telescopic member 37 and the wiping member 43, so that the gas flow path will not be blocked by impurities, thereby achieving the purpose of avoiding blockage and facilitating exhaust.

[0037] Embodiment 2: Based on embodiment 1, Figure 1 , Figure 2 , Figure 7 and Figure 8 As shown, it also includes a flipping mechanism 5, which includes a pull rope 51, a rotating wheel 52, a fixed frame 53, a sliding rod 54, a third spring 55, a first rack 56 and a one-way gear 57. The fixed frame 53 is connected to the right side of the middle position of the lower mold 2, the rotating wheel 52 is rotatably connected to the lower left part of the fixed frame 53, the sliding rod 54 is slidably connected to the right side of the middle position of the lower mold 2, the sliding rod 54 is located on the left side of the fixed frame 53, a third spring 55 is wound between the lower part of the sliding rod 54 and the lower mold 2, the third spring 55 is wound on the sliding rod 54, a pull rope 51 is connected between the lower part of the sliding rod 54 and the sliding frame 33, the pull rope 51 bypasses the rotating wheel 52, the upper part of the sliding rod 54 is connected to the first rack 56, the first rack 56 is squeezed and matched with the flip cover 22, and the right side of the air permeable member 21 is connected to the one-way gear 57, and the one-way gear 57 is meshed with the first rack 56.

[0038] In the initial state, the first rack 56 is on the upper side, the first rack 56 lifts up the flip cover 22, and the first spring 23 is in a stretched state. At this time, in order to inject plastic into the cavity of the lower mold 2, it is necessary to first refer to the process described above to control the sliding frame 33 to move upward, so that the sliding frame 33 pulls one side of the pull rope 51. Under the action of friction, the rotating wheel 52 will rotate, and the other side of the pull rope 51 will pull the sliding rod 54 downward, so that the third spring 55 is stretched, and the first rack 56 moves downward, so that the third spring 55 is stretched. A rack 56 releases the flip cover 22, and the flip cover 22 moves downward on the cover under the action of the first spring 23, so the flip cover 22 will not affect the injection molding. Driven by the first rack 56, the outer gear ring of the one-way gear 57 rotates clockwise, and at this time, the outer gear ring of the one-way gear 57 cannot drive the inner gear ring to rotate clockwise together, so the outer gear ring of the one-way gear 57 will idle, and the air-permeable member 21 remains stationary. Then, the lower side of the lower mold 2 is plugged with cloth to prevent air leakage, and then the injection is carried out normally by referring to the steps described above. The plastic machine can inject plastic and extract the gas in the plastic. After the plastic is taken out, the cloth can be taken out. The waterproof motor 34 can be started to clean the current lower side of the breathable member 21 by referring to the process described above. Then the sliding frame 33 is moved downward, so the pull rope 51 is loosened. Under the action of the third spring 55, the sliding rod 54 drives the first rack 56 to move upward, the first spring 23 is stretched, and the rotating wheel 52 rotates in the opposite direction. At this time, the first rack 56 drives the outer gear ring of the one-way gear 57 to rotate counterclockwise, and the one-way gear 57 rotates counterclockwise. The outer gear ring of the unidirectional gear 57 drives the inner gear ring of the one-way gear 57 to rotate counterclockwise, thereby causing the inner gear ring of the one-way gear 57 to drive the air-permeable member 21 to rotate counterclockwise and turn over. The original upper side of the air-permeable member 21 will now face downward, and then the process described above can be referred to to move the telescopic member 37 upward again, and allow the telescopic member 37 to clean the other side of the air-permeable member 21. In this way, the air-permeable member 21 can be further cleaned to avoid blockage of the air-permeable member 21, and then the sliding frame 33 can be moved downward to reset.

[0039] like Figure 1 , Figure 2 , Fig. 9 and Fig.10As shown, a cleaning mechanism 6 is also included, which includes a fixed block 61, an extruding member 62, a water tank 63, a nozzle 64, a torsion spring 65, a fixed member 66, a water pump 67 and a water pipe 68. The water tank 63 is connected to the lower part of the lower mold 2. The water tank 63 is divided into two left and right areas. There are two fixed blocks 61, and the two fixed blocks 61 are respectively connected to the right front side and the left rear side of the lower part of the rotating member 36. Two fixed members 66 are connected to the right side of the middle position of the lower mold 2. The nozzle 64 is rotatably connected between the fixed members 66. Both sides of the nozzle 64 Torsion springs 65 are wound between the fixing member 66, and the torsion springs 65 are wound on the nozzle 64. The lower part of the nozzle 64 is connected to the extrusion member 62, and the extrusion member 62 and the fixing block 61 are extruded and matched. A water pump 67 is connected to the right front side of the middle position of the lower mold 2, and the lower part of the water pump 67 is connected to a water pipe 68, which is connected to the water pump 67. The water pipe 68 extends into the water tank 63, and another water pipe 68 is connected between the upper part of the water pump 67 and the nozzle 64. The water pipe 68 is connected to the water pump 67, and the water pipe 68 is also connected to the nozzle 64.

[0040] In order to clean the telescopic member 37 and the wiping member 43, when the telescopic member 37 and the wiping member 43 are cleaned of impurities and are located at the bottom, people can inject clean water into the area on the right side of the water tank 63, then start the water pump 67, and then start the waterproof motor 34. The water pump 67 will pump the clean water in the area on the right side of the water tank 63 into the nozzle 64 through the water pipe 68, and spray it out through the nozzle 64. At the same time, because the output shaft of the waterproof motor 34 will drive the rotating member 36 to rotate, the rotating member 36 drives the fixed block 61 to rotate. When the fixed block 61 contacts the extruding member 62, the extruding member 62 will move downward under the extrusion of the fixed block 61, so that the nozzle 64 will swing accordingly. As the fixing block 61 continues to rotate, the extruding member 62 is gradually loosened, and the nozzle 64 is reversely swung and reset under the action of the torsion spring 65. In this way, the spraying range of the nozzle 64 is expanded, so that the nozzle 64 can spray water on the telescopic member 37 and the wiping member 43, and the impurities on the telescopic member 37 and the wiping member 43 are washed off, so that the telescopic member 37 and the wiping member 43 can also have a good cleaning effect when cleaning next time. The sewage and impurities will flow into the area on the left side of the water tank 63 and accumulate. When the telescopic member 37 and the wiping member 43 are cleaned, turn off the waterproof motor 34, turn off the water pump 67, and then clean the water in the water tank 63.

[0041] like Figure 1 , Figure 2 and Fig.11As shown, it also includes a sealing mechanism 7, which includes a second slide rail 71, a bidirectional screw 72, a second spur gear 73, a second rack 74, a connecting rod 75 and a sealing member 76. The second slide rail 71 is connected to the left side of the middle position of the lower mold 2, and the bidirectional screw 72 is rotatably connected between the front and rear sides of the second slide rail 71. The front and rear sides of the bidirectional screw 72 are both threadedly connected with sealing members 76. The sealing members 76 and the second slide rail 71 are both slidably connected. The second spur gear 73 is connected to the middle position of the bidirectional screw 72. The left part of the sliding frame 33 is connected with a connecting rod 75. The upper and lower sides of the connecting rod 75 are both connected with second racks 74, and the upper second rack 74 is short and the lower second rack 74 is long. The two second racks 74 are both meshed with the second spur gear 73.

[0042] When the second rack 74 on the lower side moves to contact with the second spur gear 73, the wiper 43 has moved upward to pass over the seal 76, and the second rack 74 drives the second spur gear 73 to rotate, so that the double-direction screw 72 can continue to drive the seal 76 to move to the side of the close direction. When the second rack 74 on the upper side is released from the second spur gear 73, the second rack 74 on the upper side will drive the second spur gear 73 to rotate in the opposite direction, thereby causing the bidirectional screw 72 to rotate in the opposite direction, and then the bidirectional screw 72 will drive the seal 76 to move to the side in the direction of moving away from each other, and then the second rack 74 on the lower side will pass over the second spur gear 73. At this time, the wiping member 43 has moved downward to pass over the seal 76. When the second rack 74 on the upper side is released from the second spur gear 73, the second rack 74 on the upper side will drive the second spur gear 73 to rotate in the opposite direction, thereby causing the bidirectional screw 72 to rotate in the opposite direction, and then the bidirectional screw 72 will continue to drive the seal 76 to move to the side in the direction of moving away from each other, thereby causing the telescopic member 37 to move downward to separate from the lower mold 2.

[0043] like Figure 2 and Fig.12As shown, a dirt removing mechanism 8 is also included, which includes a fixed tube 81, a knocking piece 82, a fourth spring 83 and a wedge block 84. Three wedge blocks 84 are connected to the upper right side of the sealing member 76. There are two fixed tubes 81, which are respectively connected to the front and rear sides of the middle position of the lower mold 2. There are two knocking pieces 82, which are respectively slidably connected to the left parts of the two fixed tubes 81. The knocking pieces 82 are in contact with the adjacent sealing members 76. The knocking pieces 82 are squeezed and matched with the three adjacent wedge blocks 84. There are two fourth springs 83, which are respectively wound between the left sides of the two knocking pieces 82 and the left sides of the adjacent fixed tubes 81. The fourth springs 83 are each wound around the corresponding knocking pieces 82.

[0044] When the seal 76 moves toward the side in the direction of approaching each other, the corresponding wedge block 84 will also move therewith. When the wedge block 84 contacts the knocking piece 82, the knocking piece 82 will move toward the side away from the seal 76, and the fourth spring 83 will be compressed. When the convex part of the wedge block 84 passes over the knocking piece 82, under the action of the fourth spring 83, the knocking piece 82 will move to the side close to the seal 76 and reset, so that the knocking piece 82 knocks the seal 76, causing the seal 76 to vibrate, and impurities on the seal 76 can fall off, thereby avoiding too many impurities adhering to the seal 76 and affecting its use. The same is true when the seal 76 moves toward the side in the direction of moving away from each other.

[0045] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
