Description

Technical Field

[0001] This utility model relates to the technical field of automotive rear door sealing strip trimming equipment, and in particular to an automotive rear door sealing strip trimming mold. Background Technology

[0002] The rear door sealing strip is an essential sealing component on the rear door of a car. It is made by casting a special-shaped sealing rubber C onto a stainless steel profile D as the skeleton. During the molding process, the excess edge of the rear door sealing strip needs to be cut off.

[0003] Currently, when trimming the excess edge of the rear door sealing strip of a car, manual assistance is still required for loading and unloading the sealing strip before the trimming operation can be carried out. The trimming mold is not automated enough, resulting in low work efficiency. In addition, there is no function to collect the waste material after trimming, and manual cleaning is required after each trimming, which is not very practical. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a cutting mold for automotive rear door sealing strips. When using the cutting mold, the operator places the sealing strip on the placement rack and starts the device. The upper and lower limit plates are moved to both sides of the excess edge of the sealing strip by the limit cylinder in the limit assembly to press and limit it, preventing the sealing strip from shifting during trimming. Then, the axial drive assembly drives the trimming blade to move axially to complete the removal of the excess edge. The cutting process is more automated, greatly improving cutting efficiency.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] A cutting mold for a car rear door sealing strip, characterized by comprising a base plate, a positioning frame, a limiting component, a trimming blade, an axial drive component, and a waste collection box. The positioning frame is screwed and fixedly mounted on the base plate. The sealing strip is placed on the positioning frame. An axial drive component for driving the trimming blade axially and a limiting component for limiting the sealing strip are installed beside the positioning frame. The axial drive component is connected to the trimming blade via a connecting frame. A waste collection box is located below the trimming blade.

[0007] The limiting assembly consists of a support rod, a limiting cylinder, a rear plate, an upper limiting plate, and a lower limiting plate. The support rod is bolted to the base plate, and the limiting cylinder is fixedly installed at the upper end of the support rod. The telescopic end of the limiting cylinder is connected to the rear plate, the upper limiting plate is fixed at the upper end of the rear plate, and the lower limiting plate is fixed at the lower end of the rear plate.

[0008] The axial drive assembly consists of a support base, an axial frame, a motor, a lead screw, a guide rod, and a moving block. Both ends of the axial frame are fixed to the support base, which is fixed to a base plate. The axial frame is located between an upper limit plate and a lower limit plate. A lead screw is axially mounted on the axial frame, with one end connected to the motor. The moving block is threaded onto the lead screw, and a guide rod passes through a guide hole in the moving block. Both ends of the guide rod are mounted on the axial frame.

[0009] The movable block is fixedly connected to the connecting frame, and the connecting frame is provided with a tool holder, on which a trimming knife is installed.

[0010] Furthermore, a baffle is provided below the axial frame, and the baffle is located between the axial frame and the lower limit plate.

[0011] Furthermore, the upper limit plate and the lower limit plate are located on both sides of the remaining edge of the sealing strip, respectively, to press and limit the remaining edge on both sides to prevent the sealing strip from shifting during trimming.

[0012] The beneficial effects of this utility model are:

[0013] When using the trimming mold designed in this utility model, the operator places the sealing strip on the placement rack and starts the equipment. The upper and lower limit plates are moved to both sides of the excess edge of the sealing strip by the limit cylinder in the limit assembly to press and limit it, so as to prevent the sealing strip from shifting when the trimming knife is trimming. Then the axial drive assembly drives the trimming knife to move axially to complete the removal of the excess edge. The trimming process is more automated and greatly improves the trimming efficiency.

[0014] This utility model provides a baffle below the axial frame, positioned between the axial frame and the lower limit plate. After the trimming is completed, the trimmed excess material falls onto the lower limit plate. When the lower limit plate is moved back to its original position by the limit cylinder, the waste material is blocked by the baffle. After the lower limit plate is moved away, the waste material falls into the waste collection box for collection and processing, making the processing environment cleaner.

[0023] Example 1

[0024] As shown in the figure, a positioning bracket 2 is fixedly installed on the base plate 1 with screws. This positioning bracket 2 is used to place the sealing strip 100.

[0025] An axial drive assembly for driving the trimming knife 5 to move axially and a limiting assembly for limiting the sealing strip 100 are installed beside the positioning frame 2. The support rod 41 in the limiting assembly is bolted to the base plate 1. A limiting cylinder 42 is fixedly installed at the upper end of the support rod 41. The telescopic end of the limiting cylinder 42 is connected to the rear plate 43. An upper limiting plate 44 is fixed at the upper end of the rear plate 43, and a lower limiting plate 45 is fixed at the lower end.

[0026] The two ends of the axial frame 62 in the axial drive assembly are fixed on the support base 61, which is fixed on the base plate 1. The height of the axial frame 62 is between the upper limit plate 44 and the lower limit plate 43. The axial frame 62 is axially mounted with a lead screw 64. One end of the lead screw 64 is connected to the motor 63. The lead screw 64 is threadedly connected to the moving block 65. The guide hole on the moving block 65 is connected by a guide rod 66. The two ends of the guide rod 66 are respectively mounted on the axial frame 62. The moving block 65 is fixedly connected to the connecting frame 3. The tool holder 51 is fixed on the connecting frame 3. The tool holder 51 is equipped with a trimming knife 5 for trimming the excess edge 101.

[0027] Furthermore, a baffle 8 is provided below the axial frame 62, the baffle 8 is located between the axial frame 62 and the lower limit plate 45, and a waste collection box 7 is provided below the axial frame 62 and next to the positioning frame 2 for holding waste.

[0028] Example 2

[0029] The cutting die designed in this utility model is mainly used for the sealing strip 100 of the rear door of a car. In use, the operator needs to place the sealing strip 100 on the positioning frame 2, and then start the equipment.

[0030] When the limiting cylinder 42 in the limiting assembly is activated, it controls the upper limiting plate 44 and the lower limiting plate 45 to move to both sides of the excess edge 101 of the sealing strip 100, thereby pressing and limiting both sides of the excess edge 101 to prevent the sealing strip from shifting during trimming.

[0031] Then, the motor 63 in the axial drive assembly that drives the trimming knife 5 to move axially is started, and the moving block 65 is controlled to move axially through the lead screw 64, thereby controlling the axial movement of the trimming knife 5 to cut off the excess edge 101, until the trimming knife 5 moves to the other end of the axial frame 62 to complete the entire cutting operation.

[0032] After the cutting is completed, since the lower limit plate 45 is located below the excess edge 101 and above the opening of the waste collection box 7, the cut excess edge 101 falls onto the lower limit plate 45 first. Therefore, when the limit cylinder 42 controls the lower limit plate 45 to reset and move, the lower limit plate 45 located below the axial frame 62 slowly moves backward. The fallen excess edge 101 will be blocked by the baffle 8 between the axial frame 62 and the lower limit plate 45 and will not move to the rear side with the lower limit plate 45. After the lower limit plate 45 is moved away, the waste falls into the waste collection box 7 below for the same collection process, making the processing environment cleaner.

[0033] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. The various components mentioned in this utility model are common technologies in the existing field. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
