Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0020] As Figure 1 As shown in - 2, a self - skinning foaming device for a suitcase carpet includes a lower mold 1. A demolding mechanism 2 is arranged at the bottom of the lower mold 1. Fixed side plates 8 are fixedly installed on both sides of the bottom of the lower mold 1. A replacement mechanism 3 is arranged on one side of the fixed side plate 8. An upper mold 4 is arranged on the top of the lower mold 1. A mounting frame 5 is fixedly installed above the lower mold 1. A cylinder 6 is fixedly installed on the top of the mounting frame 5. The output end of the cylinder 6 is fixedly connected to the top of the upper mold 4. A top plate 9 is arranged inside the lower mold 1. A metal sealing ring 10 is sleeved on the surface of the top plate 9. The metal sealing ring 10 is in contact with the inner wall of the lower mold 1. Support legs 7 are fixedly installed on both sides of the bottom of the lower mold 1.

[0021] The effects achieved by the above components are as follows: By setting the demolding mechanism 2, it is convenient to demold the carpet inside the lower mold 1, facilitating the removal of the carpet and improving the carpet demolding efficiency. By setting the replacement mechanism 3, it is convenient to keep the top plate 9 and the metal sealing ring 10 in a state of being separated from the inside of the lower mold 1, facilitating the replacement of the metal sealing ring 10, improving the service performance of the metal sealing ring 10, and avoiding the wear of the metal sealing ring 10 during long - term use, which affects the integral molding of the carpet, and further affects the wear resistance and waterproofness of the carpet.

[0022] As Figure 3As shown, the demolding mechanism 2 includes a number of push rods 201. The push rods 201 are fixedly installed at the bottom of the top plate 9. The bottom of the push rods 201 extends below the lower mold 1 and is fixedly installed with a connecting plate 202. A spring 203 is fixedly installed at the bottom of the lower mold 1. The bottom of the spring 203 is fixedly connected to the connecting plate 202. A convex block 204 is fixedly installed at the bottom of the connecting plate 202. A motor 205 is fixedly installed on one side of the fixed side plate 8. The output end of the motor 205 is fixedly installed with a lead screw 206. An extrusion block 207 is arranged between the fixed side plates 8. One side of the lead screw 206 penetrates through the extrusion block 207 and is threadedly connected to the extrusion block 207.

[0023] The effects achieved by the above components are as follows: By setting the motor 205 to drive the lead screw 206 to rotate, and then the lead screw 206 drives the extrusion block 207 to move, so that the extrusion block 207 moves in the direction close to the convex block 204. The extrusion block 207 will squeeze the bottom of the convex block 204, causing the convex block 204 to move upward. The convex block 204 drives the connecting plate 202 and the push rod 201 to move upward. Further, the push rod 201 pushes the top plate 9 and the metal sealing ring 10 upward, thereby ejecting the carpet inside the lower mold 1, facilitating the demolding of the carpet. When the extrusion block 207 moves to the other side of the convex block 204, under the elastic force of the spring 203, the top plate 9 and the metal sealing ring 10 are pulled back and reset, facilitating the next processing.

[0024] As Figure 3 shown, a guide rod 208 is fixedly installed between the fixed side plates 8. A guide hole is formed inside the extrusion block 207, and the guide rod 208 penetrates through the guide hole.

[0025] The effects achieved by the above components are as follows: By setting the guide rod 208 and the guide hole to cooperate with each other to limit the extrusion block 207, the stability of the extrusion block 207 during left and right movement is improved, and further the stability of the extrusion block 207 when squeezing the convex block 204 is improved.

[0026] As Figure 3 shown, the top of the extrusion block 207 and the bottom of the convex block 204 are both arranged in an arc shape.

[0027] The effects achieved by the above components are as follows: By arranging the top of the extrusion block 207 and the bottom of the convex block 204 in an arc shape, it is convenient for the extrusion block 207 to squeeze the convex block 204, reducing the resistance between the extrusion block 207 and the convex block 204.

[0028] As Figure 4As shown in the figure, the replacement mechanism 3 includes a fixed rod 301. The fixed rod 301 is fixedly installed on one side of the connecting plate 202. A side rod 303 is fixedly installed on the side of the fixed rod 301 close to the fixed side plate 8. A limiting groove 302 is formed inside the fixed side plate 8. The other end of the side rod 303 penetrates through the limiting groove 302. Two limiting rings 305 are fixedly installed at the other end of the side rod 303. A movable plate 306 is arranged on one side of the side rod 303. A clamping rod 307 is fixedly installed on the side of the movable plate 306 close to the limiting ring 305. One side of the clamping rod 307 penetrates through the limiting ring 305. A clamping groove 304 is formed on the side of the fixed side plate 8 close to the limiting ring 305. The size of the clamping rod 307 is adapted to the size of the clamping groove 304.

[0029] The effects achieved by the above components are as follows: When it is necessary to replace the metal sealing ring 10, the top plate 9 and the metal sealing ring 10 need to be moved to be separated from the inside of the lower die 1. The connecting plate 202 is moved upward, so that the outer ring of the top plate 9 and the metal sealing ring 10 is separated from the inside of the lower die 1. The connecting plate 202 drives the fixed rod 301 and the side rod 303 to move upward. The side rod 303 moves upward inside the limiting groove 302. When the side rod 303 moves to the top inside the limiting groove 302, the limiting ring 305 is located on one side of the clamping groove 304. At this time, the movable plate 306 is driven to drive the clamping rod 307 to move, so that one side of the clamping rod 307 penetrates through the limiting ring 305 and is clamped inside the clamping groove 304.

[0030] As Figure 4 shown in the figure, one side of the side rod 303 is connected by a bearing to a screw rod 308. The other side of the screw rod 308 penetrates through the movable plate 306 and is threadedly connected to the movable plate 306. A baffle is fixedly installed on the surface of the screw rod 308, and the baffle is clamped on one side of the movable plate 306.

[0031] The effects achieved by the above components are as follows: By arranging the screw rod 308 to drive the movable plate 306 to move, it is convenient for the movable plate 306 to drive the clamping rod 307 to move, so that one side of the clamping rod 307 is clamped inside the clamping groove 304, facilitating the state that the top plate 9 and the metal sealing ring 10 are separated from the inside of the lower die 1 and convenient for replacing the metal sealing ring 10.

[0032] The working principle of this kind of self-skinning foaming device for suitcase carpet:

[0033] The motor 205 drives the lead screw 206 to rotate. Further, the lead screw 206 drives the extrusion block 207 to move, causing the extrusion block 207 to move in the direction closer to the convex block 204. The extrusion block 207 will exert extrusion on the bottom of the convex block 204, causing the convex block 204 to move upward. The convex block 204 drives the connecting plate 202 and the push rod 201 to move upward. Further, the push rod 201 pushes the top plate 9 and the metal sealing ring 10 upward, thereby ejecting the carpet inside the lower mold 1, facilitating the demolding of the carpet. When the extrusion block 207 moves to the other side of the convex block 204, under the elastic force of the spring 203, the top plate 9 and the metal sealing ring 10 are pulled back and reset, facilitating the next processing;

[0034] When the metal sealing ring 10 needs to be replaced, the top plate 9 and the metal sealing ring 10 need to be moved to be separated from the inside of the lower mold 1. The connecting plate 202 is moved upward, causing the outer ring of the top plate 9 and the metal sealing ring 10 to be separated from the inside of the lower mold 1. The connecting plate 202 drives the fixing rod 301 and the side rod 303 to move upward. The side rod 303 moves upward inside the limiting groove 302. When the side rod 303 moves to the top inside the limiting groove 302, the limiting ring 305 is located on one side of the clamping groove 304. At this time, the movable plate 306 is driven to drive the clamping rod 307 to move, so that one side of the clamping rod 307 penetrates through the limiting ring 305 and is clamped inside the clamping groove 304.

[0035] Obviously, the above embodiments of the present invention are merely examples for clearly explaining the present invention, rather than limitations on the implementation manners of the present invention. For those of ordinary skill in the art, other different forms of changes or variations can be made based on the above description. It is impossible to list all the implementation manners here. Any obvious changes or variations derived from the technical solutions of the present invention still fall within the protection scope of the present invention.
