Description

Technical Field

[0001] The utility model relates to the technical field of trimming moulds, and in particular to a trimming mould for a sealing strip of a rear door of an automobile. Background Art

[0002] Car is one of the common means of transportation. The rear door of a car is the door located at the rear side of the car. The door sealing strip is a product that seals the door to make it difficult to open, and plays the role of shock absorption, waterproofing, sound insulation, heat insulation, dust prevention, and fixation. It is mainly used in door panels, door frames, side windows, front and rear windshields, engine hoods and trunk lids, and plays the role of waterproofing, dust prevention, sound insulation, heat insulation, shock absorption, decoration and other fields. Usually, the sealing strip will have burrs when it is just produced. In order to improve the appearance of the sealing strip, the burrs need to be cut off, so a trimming device is needed.

[0003] The existing patent publication number CN210757908U discloses a trimming mold for the sealing strip of a rear door of an automobile, which belongs to the technical field of automobile parts production. It includes a base, a knife groove is provided on one side of the top of the base, and a slide groove is provided on the other side of the top of the base. A slider is slidably connected to the top of the slide groove, an adjusting plate is fixedly connected to the top of the slider, and a fixing frame is fixedly connected to the top of the base. An electric lifting rod is installed on the top of the fixing frame, which can adjust the position of the adjusting plate and thus adjust the spacing between the adjusting plate and the knife groove on the top of the base by moving the slider. By changing the position of the adjusting plate, the width of sealing strips of different specifications can be conveniently cut. The mold is flexible to use and easy to adjust. The lifting and lowering of the mounting plate and the knife holder can be controlled by controlling the lifting and lowering of the electric lifting rod, thereby achieving the purpose of controlling the height of the cutter. The cutting knife can be pressed down to cut the sealing strip, and the cutting process is automatically completed, which is both efficient and accurate.

[0004] The above scheme has the following problems during implementation. The device adjusts the cutting width of the sealing strip by making one side of the sealing strip contact with the adjustment plate and then adjusting the distance between the adjustment plate and the knife groove. After the cutting width of the sealing strip is adjusted, the device is not convenient for fixing the sealing body. Only when cutting is performed, the fixing block will fall together with the cutter to fix the sealing strip. However, during the short time when the fixing block falls, the sealing strip is likely to shift due to external factors such as vibration or accidental touch. At this time, if it is fixed and cut, the sealing strip has already shifted, which will lead to inaccurate cutting, affecting the quality of the sealing strip and greatly reducing the practicality of the device. To this end, we provide a car rear door sealing strip trimming mold to solve the above problems. Utility Model Content
