[0051] The specific implementation of the embodiment of the utility model is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the embodiment of the utility model, and is not used to limit the embodiment of the utility model.

[0052] Figure 1 It is a structural schematic diagram of an online trimming device for door seals according to an embodiment of the utility model; Figure 2 is based on Figure 1 A magnified schematic diagram of the middle A area; Figure 3 is a cross-sectional view of an in-line trimming device for a door seal according to an embodiment of the utility model; Figure 4 is based on Figure 3 A magnified schematic diagram of area B. Figures 1 to 4 In the embodiment, the door seal online trimming device may include a trimming seat 4, a mold seat 13 and a cutting assembly. Specifically, the mold seat 13 may include a mold groove 14 and a sealing opening 15.

[0053] The mold base 13 is arranged on the top of the trimming base 4, the mold groove 14 is opened inside the mold base 13, and the edge sealing opening 15 is opened on the side wall of the mold base 13 and communicates with the inner bottom of the mold groove 14. The cutting assembly is arranged on the side wall of the mold base 13 close to the edge sealing opening 15 and fits with the side wall of the mold base 13, and is used to shape and cut the door edge extending out of the edge sealing opening 15. Specifically, the shaping and cutting is cutting according to a preset shape.

[0054] When the door sealing edge of the door seal needs to be cut, the door seal is inserted along one end of the mold groove 14, the door sealing edge enters along the sealing edge opening 15, and the door seal is pulled to move along the inside of the mold groove 14. After the door sealing edge of the door seal reaches the position to be cut, the cutting assembly is started, and the cutting assembly cooperates with the side wall of the mold base 13 to cut the door sealing edge of the door seal to form the actual required cutting shape.

[0055] Traditional door edge cutting mostly uses manual auxiliary cutting tools to cut according to a certain shape, but this cutting method is inefficient, has poor cutting effect, and has certain safety hazards. In this embodiment of the utility model, the cutting assembly is used in conjunction with the mold base 13 to perform shaping cutting on the door edge, which can effectively improve the cutting efficiency and effect of the door edge and reduce safety hazards.

[0056] In this embodiment of the present invention, if Figure 1 as well as Figure 2 As shown, the cutting assembly may include a cutting knife 10 and a driving assembly 7 .

[0057] The side of the cutting knife 10 close to the edge sealing opening 15 is in contact with the side wall of the mold seat 13. The driving assembly 7 is arranged on the top of the edge cutting seat 4, and the output end of the driving assembly 7 is connected to the top of the cutting knife 10, so as to drive the cutting knife 10 to move up and down along the side wall of the mold seat 13 and cut the door edge of the door seal.

[0058] When the door seal edge of the door seal needs to be cut, the driving component 7 is started, and the driving component 7 drives the cutting knife 10 to descend and cut the extended door seal edge. After the cutting is completed, the driving component 7 drives the cutting knife 10 to reset and wait for the next cutting. Specifically, the cutting method using the driving component 7 to drive the cutting knife 10 has high cutting efficiency and is simple and convenient.

[0059] In this embodiment of the utility model, the shape of the cutting knife 10 can be various forms known to those skilled in the art, such as a blade shape. However, in a preferred embodiment of the utility model, considering the stability and effect of shaping and cutting the door edge, the specific shape of the cutting knife 10 can be as follows: Figure 1 and Figure 2 Specifically, Figure 1 and Figure 2 In the embodiment, the shape of the cutting blade 10 includes a block shape, and the two ends of the cutting blade 10 close to the edge sealing opening 15 are provided with symmetrical first inclined surfaces 11. Specifically, the cutting edges of the block-shaped cutting blade 10, that is, the three bottom edges close to the mold seat 13, are all sharp.

[0060] In this embodiment of the present invention, if Figure 1 and Figure 2 As shown, the cutting assembly further includes two groups of inclined seats 12. Specifically, the inclined seats 12 may include a second inclined surface and an edge sealing groove.

[0061] Two sets of inclined seats 12 are arranged on the side wall of the mold seat 13 and are respectively located at both ends of the cutting knife 10. The second inclined surface is in contact with the corresponding first inclined surface 11, and the edge sealing groove is opened on the side of the inclined seat 12 close to the mold seat 13, which is used to limit the edge sealing of the door extending out of the edge sealing opening 15.

[0062] The two sets of inclined seats 12 can cooperate with the mold seat 13 to limit the cutting shape and cutting position of the cutting knife 10 on the door edge. And because the edge sealing groove can cooperate with the edge sealing opening 15 to limit the door edge sealing at the non-cutting position of the door edge, the cutting effect of the cutting knife 10 is good. In addition, the inclination angle of the first inclined surface 11 and the second inclined surface can be determined according to the actual required angle of cutting the door edge. Specifically, the two sets of inclined seats 12 and the mold seat 13 are used to fit the three sides of the cutting knife 10, which can further improve the cutting effect of the cutting knife 10.

[0063] In this embodiment of the present invention, if Figure 1 As shown, the cutting assembly may further include a plurality of guide seats 8 and a plurality of slide seats 9.

[0064] Multiple sets of guide seats 8 are arranged on the top of the trimming seat 4 and are located on the side of the cutting knife 10 away from the mold seat 13. Multiple sets of slide seats 9 are arranged on the side of the cutting knife 10 away from the mold seat 13, and the slide seats 9 are slidably connected with the corresponding guide seats 8.

[0065] During the cutting and resetting process of the cutting knife 10, the slide 9 is driven to slide along the guide seat 8, that is, the slide 9 and the guide seat 8 can cooperate to guide the cutting knife 10 to move, so as to improve the stability and reliability of the cutting knife 10 during the cutting process.

[0066] In this embodiment of the present invention, if Figure 5As shown, the bottom of the cutting knife 10 is provided with an arc surface 19. Specifically, the middle of the bottom of the cutting knife 10 is concave inward. Therefore, when the cutting knife 10 cuts the door edge, the two ends of the bottom of the cutting knife 10 first cut the door edge, and then gradually cut the middle of the door edge. This cutting method from the two ends to the middle effectively disperses the stress of the door edge during cutting, avoids deformation of the door edge during cutting, and further improves the effect of cutting the door edge.

[0067] In this embodiment of the present invention, if Figure 1 and Figure 2 As shown, the driving assembly 7 may include a fixing seat 6 and a driving cylinder 5 .

[0068] The fixing seat 6 is arranged on the top of the trimming seat 4 , the driving cylinder 5 is arranged on the fixing seat 6 , and the output end of the driving cylinder 5 is fixedly connected to the top of the cutting knife 10 .

[0069] When the door edge needs to be cut, the driving cylinder 5 is started, and the driving cylinder 5 drives the rod cutting knife 10 to move downward to cut the door edge. Conversely, the driving cylinder 5 is controlled to move in the reverse direction to drive the cutting knife 10 to reset.

[0070] In this embodiment of the present invention, if Figure 1 and, Figure 3 and Figure 4 As shown, the trimming seat 4 may include a support frame 2, a support plate 1 and a recovery box 3. Specifically, the support plate 1 may include a recovery port 16.

[0071] The support plate 1 is arranged on the top of the support frame 2, and the support plate 1 is provided with a recovery port 16 directly below the cutting blade 10. The recovery box 3 is arranged at the inner bottom of the support frame 2, and the top of the recovery box 3 is open, and is used to cooperate with the recovery port 16 to recover the cut door edge.

[0072] After the cutting knife 10 cuts the door edge seal, the cut door edge seal falls along the recovery port 16 into the recovery box 3 for recovery, thereby facilitating the unified treatment of the cut waste.

[0073] In this embodiment of the present invention, if Figure 6 As shown, the number of the trimming seat 4, the mold seat 13 and the cutting assembly can include two groups. Specifically, the two groups of trimming seats 4, the mold seat 13 and the cutting assembly are symmetrically arranged along the conveying direction of the door seal.

[0074] For the two cutting components, the same cutting specifications can be adopted, that is, the specifications of the cutting blades 10 in the cutting components are consistent. The method of cutting with two cutting structures at the same time can effectively improve the cutting efficiency. For the two cutting components, different cutting specifications can also be adopted, that is, the specifications of the cutting blades 10 in the cutting components are inconsistent. The method of cutting with two cutting structures for different sizes can effectively improve the versatility of cutting.

[0075] In this embodiment of the present invention, if Figure 1 As shown, considering that the door seal generally moves in a fixed direction under the action of a traction machine after injection molding, in order to improve the versatility of cutting the door seal after injection molding, the door seal online trimming device can also include a base 17 and a moving component 18.

[0076] The moving assembly 18 is arranged on the top of the base 17 , and the bottom of the trimming seat 4 is connected to the output end of the moving assembly 18 . The moving assembly 18 is used to drive the trimming seat 4 to move in a direction perpendicular to the conveying direction of the door seal.

[0077] When it is necessary to switch the cutting specifications to perform door edge cutting of different sizes, the moving component 18 is started, and the moving component 18 drives the edge cutting seat 4 to move so that the corresponding cutting structure is directly opposite to the door seal delivered in the previous process, so that the door seal can stably enter the corresponding mold groove 14.

[0078] In this embodiment of the present invention, the specific structure of the moving component 18 includes but is not limited to a ball screw, a cylinder, etc. known to those skilled in the art.

[0079] Through the above technical scheme, the online trimming device for door seals provided by the utility model realizes the limited conveying of the door seals by allowing the door seals formed by injection molding to pass along the mold groove, and the door sealing edge of the door seals passes along the sealing edge opening. When it is necessary to cut the side of the door sealing edge, the cutting component is driven to start, and the cutting component cooperates with the mold base to limit the door sealing edge, so that the door sealing edge extending out of the sealing edge opening can be stably shaped and cut, that is, it is cut according to a preset shape. The method of shaping and cutting the door sealing edge by using the cutting component in cooperation with the mold base can effectively improve the cutting efficiency and effect of the door sealing edge, and reduce safety hazards.

[0080] It should also be noted that the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, commodity or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, commodity or device. In the absence of more restrictions, the elements defined by the sentence "comprises a ..." do not exclude the existence of other identical elements in the process, method, commodity or device including the elements.

[0081] The above are only embodiments of the present application and are not intended to limit the present application.
