Description

Technical Field

[0001] This utility model relates to the field of automobile roof manufacturing, and in particular to a pressing mold for installing the bracket of the interior light of the automobile roof. Background Technology

[0002] One step in manufacturing a car headliner is installing interior light brackets. These brackets consist of a rectangular bracket panel with its inner edges protruding upwards to form an upper convex frame. Operators use a pressing mold to install the brackets, following these steps: The operator takes the car headliner and places it on the top wall of the lower mold of the pressing mold; adhesive is applied to the area of ​​the headliner where the interior light brackets will be installed. Then, the operator takes the interior light bracket and adheres it to the corresponding area of ​​the headliner. The bottom wall of the upper mold is flat, pressing down on the upper convex part of the interior light bracket to ensure the panel is firmly adhered to the headliner. The drawback of the existing technology is that when operators manually adhere the interior light bracket panel to the headliner, they may accidentally stick it crookedly, causing misalignment of the interior light brackets on the headliner. Utility Model Content

[0003] The present invention aims to provide a pressing mold for installing the interior light bracket of a car roof, so as to prevent the interior light bracket panel from being glued crookedly to the corresponding part of the car roof.

[0004] A pressing mold for installing an interior light bracket for an automotive headliner includes an upper mold, a lower convex frame mounted on the bottom wall of the upper mold, a movable pressing block surrounded by the lower convex frame, and a driving device. The lower convex frame accommodates the upper convex frame of the interior light bracket through the gap between its inner sidewall and the movable pressing block. The movable pressing block is driven by the driving device to move laterally and press the upper convex frame laterally onto the inner sidewall of the lower convex frame.

[0005] Furthermore, a first notch is partially opened on the bottom wall of the lower convex frame, the first notch leading upward to the bottom wall of the upper mold, and a first optical coupler sensor is installed vertically downward on the part of the bottom wall of the upper mold located within the first notch. The first optical coupler sensor detects the distance between itself and the top wall of the interior light bracket panel; the upper mold is equipped with a controller, and the controller is connected to the first optical coupler sensor.

[0006] Furthermore, the bottom wall of the first optocoupler sensor is located lower than the bottom wall of the lower convex frame.

[0007] Furthermore, a second notch is partially provided on the bottom wall of the lower convex frame; a second optical coupler sensor, which is surrounded by the lower convex frame, is installed on the bottom wall of the upper mold, and the second optical coupler sensor is laterally aligned with the second notch; the second optical coupler sensor is connected to the controller.

[0008] The beneficial effect is that the operator no longer needs to manually glue the bottom wall of the interior light bracket panel to the corresponding part of the car roof. Instead, the operator lifts up the upper convex frame of the interior light bracket and places it into the gap between the inner wall of the lower convex frame and the movable pressure block. The movable pressure block presses the upper convex frame laterally onto the inner wall of the lower convex frame. On the one hand, this allows the interior light bracket to be temporarily mounted on the bottom wall of the upper mold. On the other hand, the inner wall of the lower convex frame corrects the position of the interior light bracket to prevent it from being installed crookedly. When the interior light bracket is pressed down by the upper mold and glued to the corresponding part of the car roof, it will not be misaligned. Attached Figure Description

[0010] The present invention will be further described in detail below with reference to specific embodiments.

[0011] The upper mold 1 of this pressing mold is as follows Figure 1 As shown, the bottom wall of the upper mold 1 is equipped with a lower protruding frame 2. Two first notches 3 are partially formed in the left half of the bottom wall of the lower protruding frame 2, opening upwards to the bottom wall of the upper mold 1. A vertically downward-facing first optocoupler sensor 4 is installed within the first notches 3 on the bottom wall of the upper mold 1. A second notch 8 is partially formed in the left half of the bottom wall of the lower protruding frame 2, opening upwards to the bottom wall of the upper mold 1. A second optocoupler sensor 7 is installed within the area enclosed by the lower protruding frame 2 on the bottom wall of the upper mold 1, and the second optocoupler sensor 7 is horizontally aligned with the second notch 8.

[0012] The bottom wall of the upper mold 1 has two mounting slots 13 within the area enclosed by the lower convex frame 2. Each mounting slot 13 contains a front and rear transverse cylinder (obscured in the figure). Movable pressure blocks 5 are mounted on the drive rods of the front and rear transverse cylinders, extending downwards beyond the mounting slots 13 and flush with the bottom wall of the lower convex frame 2. The upper mold 1 is equipped with a controller (not shown in the figure), which connects to the first optocoupler sensor 4, the second optocoupler sensor 7, and the two front and rear transverse cylinders.

[0013] The interior light bracket includes a square-shaped interior light bracket panel 9, with the inner edge of the square protruding upwards to form an upper convex frame 10. The outer wall of the upper convex frame 10 matches the shape and size of the inner wall 11 of the lower convex frame. The installation process of the interior light bracket is described in detail below.

[0014] The operator lifts the bottom wall of the interior light bracket panel 9, inserting the upper convex frame 10 of the interior light bracket upwards into the gap 14 between the inner wall 11 of the lower convex frame and the movable pressure block 5. During this process: the first photocoupler sensor 4 detects that the distance between itself and the top wall of the interior light bracket panel 9 has decreased to a preset value and sends a position signal A to the controller; the detection light emitted by the second photocoupler sensor 7, which normally passes laterally through the second notch 8 to the outside of the lower convex frame 2, will not normally detect a feedback signal. Once a feedback signal is detected, it means that the second notch 8 is blocked by the upper convex frame 10, and a position signal B is sent to the controller. Upon receiving the position signals A and B, the controller controls the two front and rear lateral cylinders to extend in opposite directions. The two movable pressure blocks 5 are driven by the corresponding front and rear lateral cylinders to move laterally toward the corresponding gap 14 until the upper convex frame 10 is laterally pressed onto the inner wall 11 of the lower convex frame. Figure 2 As shown. The operator takes the car roof and places it on the top wall of the lower mold of the pressing mold, applying adhesive to the area of ​​the car roof where the interior light bracket needs to be installed. Then the upper mold 1 moves down, sticking the bottom wall of the interior light bracket panel 9 to the car roof.

[0015] In a less preferred embodiment, the mounting slot can be omitted, and two front and rear transverse cylinders are positioned back-to-back between two movable pressure blocks 5, mounted on the bottom wall of the upper mold 1, with the end of the drive shaft connected to the side wall of the corresponding movable pressure block 5.

[0016] The above description is merely an embodiment of this utility model and does not limit the scope of patent protection. Any non-substantial changes or substitutions made by those skilled in the art based on this utility model will still fall within the scope of patent protection.
