Those skilled in the art can make adjustments according to needs to adapt to specific application scenarios.

[0025] In the description of the embodiments of this application, it should be noted that unless otherwise clearly specified and limited, the terms "fixed" and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of this application can be understood according to specific situations.

[0026] In the description of this utility model, it should be noted that the orientation or positional relationship indicated by the terms "upper end", "lower end", "front and back", "left and right", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing this utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0027] The following further elaborates on this application in detail with reference to the drawings and specific embodiments.

[0028] See Figures 1 to 5 As shown, the embodiments of this application disclose an automotive interior front and rear carpet lap pressing device, including a frame 1. The frame 1 is a rectangular structure, which includes a bottom plate and a top plate symmetrically arranged up and down, and the bottom plate and the top plate are connected by four columns. On the top plate of the frame 1, there is an upper mold core 2 and a pressing drive cylinder 3 for driving the upper mold core 2 to move up and down. Here, the pressing drive cylinder 3 is a vertically arranged oil cylinder. In some other embodiments, the pressing drive cylinder 3 can also be a cylinder or an electric push cylinder.

[0029] At the rear end of the bottom plate of the frame 1, a rear fixed mold core 4 for placing and positioning the rear carpet is provided. At the front end of the bottom plate, a movable plate 5 and a transverse movement driving assembly 6 for driving the movable plate 5 to move back and forth along the frame 1 are provided. A lifting plate 7 that can move vertically is connected to the movable plate 5, and a lifting driving assembly for driving the lifting plate 7 to move up and down is provided. A front movable mold core for placing and positioning the front carpet is provided on the lifting plate 7. In this embodiment, the transverse movement driving assembly 6 includes two transverse movement driving cylinders extending in the front-back direction of the frame 1. The driving ends of the two transverse movement driving cylinders are connected to the movable plate 5, and the movable plate 5 is slidably connected to the bottom plate through a linear guide rail assembly.

[0030] In the structure of this embodiment, a front movable mold core and a rear fixed mold core 4 are respectively provided on the bottom plate to support and limit the front and rear two carpets. And under the action of the transverse movement driving assembly 6 and the lifting driving assembly, the front movable mold core can adjust its position back and forth and up and down, so that the rear carpet on the rear fixed mold core 4 and the front carpet on the front movable mold core are overlapped up and down with accurate positions in a staggered manner. And after the overlapping is completed, the pressing driving cylinder 3 drives the upper mold core 2 to descend until it is pressed on the staggered overlapping part of the front and rear carpets to realize the pressing of the overlapping part. In this structure, before the front and rear carpets are positioned, glue needs to be applied at the overlapping position to ensure that the front and rear carpets can be firmly connected together after overlapping and pressing.

[0031] In the above structure, in order to ensure the smoothness of the up and down movement of the upper mold core 2, vertically extending linear slide rails 30 are provided on the four columns between the top plate and the bottom plate. A horizontally arranged fixing plate 31 is connected to the driving end at the lower end of the pressing driving cylinder 3. The four corner positions of the fixing plate 31 are respectively slidably connected to the four linear slide rails 30 through sliders 32, and the upper mold core 2 is connected to the middle of the fixing plate 31. On the other hand, in this embodiment, in order to prevent a safety accident from occurring due to the fall of the upper mold core 2 caused by a failure of the pressing driving cylinder 3 when the device is in a non-use state, two insertion holes are opened on the top plate. Correspondingly, two insertion plates are connected to the upper end surface of the fixing plate 31, and positioning jacks are provided at the upper ends of the insertion plates. Positioning cylinders 26 are respectively installed at positions on the top plate corresponding to the two insertion holes. The driving ends of the two positioning cylinders 26 are both connected with positioning pins. When the device is in a non-use state or when replacing the carpet at the work station, the fixing plate 31 moves up to the highest point, and the two positioning cylinders 26 drive the positioning pins to move horizontally until they are inserted and limited in the positioning jacks of the two insertion plates.

[0032] In this embodiment, after the front and rear carpets are placed on the upper ends of the front moving mold core and the rear fixed mold core 4 at a set angle, they are both pressed and limited by specific limiters. Specifically, a first flipping cylinder 8 and a second flipping cylinder 9 are connected to the bottom plate and / or the rear fixed mold core 4. A first pressing block 10 for pressing and limiting the rear side wall of the rear carpet is connected to the flipping arm of the first flipping cylinder 8; a second pressing block 11 for pressing and limiting the upper surface of the rear carpet is connected to the flipping arm of the second flipping cylinder. More specifically in this structure, two second flipping cylinders 9 and one first flipping cylinder 8 are provided, and the two second flipping cylinders 9 are symmetrically arranged at the left and right ends of the rear fixed mold core 4. Second pressing blocks 11 are connected to the flipping arms of the two second flipping cylinders 9 to achieve vertical pressing on the upper end surface of the rear carpet and limit the position of the rear carpet on the rear fixed mold core 4.

[0033] Similarly, a third flipping cylinder 12 and a rotating lifting cylinder 13 are connected to the lifting plate 7 and / or the front moving mold core. A third pressing block 14 for pressing and limiting the front side wall of the front carpet is connected to the flipping arm of the third flipping cylinder 12, and a fourth pressing block 15 for vertically pressing the upper end surface of the outer peripheral skirt of the front carpet is connected to the driving wall of the rotating lifting cylinder 13. Specifically, there are also two rotating lifting cylinders 13, which are symmetrically arranged on the left and right sides of the front moving mold core to achieve pressing and limiting of the skirts on both sides of the front carpet. The third flipping cylinder 12 is located in the middle of the front moving mold core and is used to press the front carpet forward and backward and limit it on the front moving mold core. At the same time, combined with the two vertically pressing fourth pressing blocks 15, stable limiting of the front carpet is achieved.

[0034] In this embodiment, four ejector rods 16 for preventing the front side of the rear carpet from collapsing and four ejector cylinders for respectively driving the ejector rods 16 to lift and lower are provided on the rear fixed mold core 4. Specifically, four mounting holes arranged at intervals in the left-right direction are concavely provided on the upper end surface of the rear fixed mold core 4, and ejector cylinders are respectively installed in the four mounting holes. The four ejector rods 16 extend in the front-rear direction and are arranged parallel to each other. One ends of the four ejector rods 16 are respectively connected to the driving ends of the four ejector cylinders, and the other ends of the four ejector rods 16 extend towards the front moving mold core direction to support the front end of the rear carpet. Because the front end part of the rear carpet protrudes outward from the rear fixed mold core 4 during positioning, the front end part of the rear carpet without the support of the mold core is prone to collapse and deform downward, resulting in unevenness after overlapping and pressing. Therefore, the arrangement of the four ejector rods 16 in this structure can prevent the front end part of the rear carpet from collapsing and deforming.

[0035] In addition, in order to further ensure the flatness of the overlapping and pressing parts of the front and rear carpets and avoid height differences, the front moving die core in this structure includes a first moving die core 17 and a second moving die core 18 that are distributed before and after along the lifting plate 7. The second moving die core 18 is slidably connected to the lifting plate 7 before and after through a linear guide rail, and a translation driving cylinder 19 for driving the second moving die core 18 to move back and forth is arranged on the lifting plate 7. After the transverse cylinder drives the front moving die core to move backward in place, the second moving die core 18 continues to move backward a short distance under the action of the translation driving cylinder 19, so that the misaligned overlapping part of the front and rear carpets can be better supported on the upper end of the second moving die core 18, ensuring that the overlapping part can be stably and firmly pressed together after the upper die core 2 is pressed.

[0036] In this embodiment, the lifting drive assembly includes a number of lifting drive cylinders 20 vertically connected to the movable plate 5. The piston rods of the lifting drive cylinders 20 are connected to the lower end surface of the lifting plate 7. A limit assembly for defining the up and down movement stroke of the lifting plate 7 is arranged between the lifting plate 7 and the movable plate 5. Specifically, upper pull plates 21 are connected to the left and right ends of the lower end surface of the lifting plate 7, and upper limit blocks 22 are arranged on the outer walls of the lower ends of the two upper pull plates 21; two lower pull plates 23 are correspondingly connected to the upper end surface of the movable plate 5, and lower limit blocks 24 for abutting and limiting with the upper limit blocks 22 are arranged on the outer walls of the upper ends of the two lower pull plates 23. When the lifting plate 7 rises to the limit height, the lower limit blocks 24 abut against the upper end surfaces of the upper limit blocks 22, restricting the further lifting of the lifting plate 7, ensuring the flatness of the overlapping and pressing parts of the front and rear carpets, and avoiding height differences.

[0037] More specifically, an upper positioning seat 25 is also convexly arranged on the lower end surface of the lifting plate 7. A positioning cylinder 26 is arranged on the movable plate 5. A lower positioning support block 27 is connected to the piston rod of the positioning cylinder 26. When the lifting plate 7 rises to the limit height, the positioning cylinder 26 drives the lower positioning support block 27 to move to abut against the lower end of the upper positioning seat 25, which is used to prevent the lifting plate 7 from descending during the pressing process. And when the lifting plate 7 descends to the lowest point, the lower end surface of the upper positioning seat 25 abuts against the upper end surface of the movable plate 5, realizing stable positioning when the lifting plate 7 falls back to its original position.

[0038] In addition, safety light curtains are respectively arranged on the four columns to ensure the personal safety of the operating workers. And an air storage tank is arranged on the top plate to supply air to each driving cylinder, eliminating the compressor and facilitating the movement of the entire equipment.

[0039] See attached Figure 2, in this embodiment, upper positioning columns 28 are arranged at both ends of the lower end surface of the upper die insert 2, and positioning protrusions are provided on the lower ends of the two upper positioning columns 28 protruding outward; two lower positioning columns 29 corresponding to the upper positioning columns 28 respectively are connected to both ends of the bottom plate, and positioning grooves for the positioning protrusions to cooperate are provided inwards concave at the upper ends of the two lower positioning columns 29, so as to limit the pressing height of the upper die insert 2 and avoid damage to the front and rear carpet pressing surfaces or deformation of equipment parts caused by excessive pressing force.
