[0001] This utility model relates to the field of automotive wheel arch technology, and in particular to a rear wheel arch frame and injection molding feeding mechanism. Background Technology

[0002] Wheel arches are the semi-circular protrusions on the fenders of a car's tires; they are commonly referred to as wheel eyebrows. Wheel arches are primarily for decorative purposes and to meet the personalized needs of drivers. At the same time, from an aerodynamic perspective, wheel arches also contribute to reducing wind resistance.

[0003] Currently, existing injection molding machines are usually connected to the feed hopper. When injection molding the wheel arch frame, external impurities may enter the injection molding machine through the feed hopper, which will reduce the quality of the injection molded rear wheel arch frame and make the rear wheel arch frame unusable. Utility Model Content

[0004] The purpose of this invention is to provide a rear wheel arch frame and an injection feeding mechanism, which aims to solve the problem that external impurities may enter the injection molding machine through the feed hopper during the injection molding of the wheel arch frame, resulting in a decrease in the quality of the injection molded rear wheel arch frame.

The sleeve is threadedly connected to the screw and located around the screw. The movable cylinder is mounted on the sleeve. The movable plate is mounted on the movable cylinder. The feed hopper is mounted on the movable plate.

[0007] The movable cylinder includes a cylinder body, a slide rail, and a slider. The cylinder body is fixedly connected to the sleeve and is located on one side of the sleeve. The slide rail is fixedly connected to the mounting frame and is located inside the mounting frame. The slider is slidably connected to the slide rail and is fixedly connected to the cylinder body.

[0008] The movable plate includes a plate body, a rotating component, and a supporting plate. The plate body is fixedly connected to the cylinder and located on one side of the cylinder. The rotating component is installed on one side of the plate body, and the supporting plate is installed on the rotating component.

[0009] The rotating component includes a rotating rod, a knob, a horizontal plate, and a guide rod. The rotating rod is threadedly connected to the plate body and is located on one side of the plate body. The knob is fixedly connected to the rotating rod and is located on the rotating rod. The horizontal plate is rotatably connected to the rotating rod and fixedly connected to the abutment plate.

[0019] Please see Figures 1-3 In the first aspect, this utility model provides an injection feeding mechanism for a rear wheel arch frame, including a mounting frame 1, a feeding hopper 2 and a closing mechanism, wherein the closing mechanism includes a turntable 3, a screw 4, a sleeve 5, a moving cylinder and a moving plate;

[0020] The mounting bracket 1 is mounted on the injection molding machine. The feed hopper 2 is mounted on the mounting bracket 1. The turntable 3 is rotatably connected to the mounting bracket 1 and is located on the mounting bracket 1. The screw 4 is fixedly connected to the turntable 3 and is located on one side of the turntable 3. The sleeve 5 is threadedly connected to the screw 4 and is located around the screw 4. The movable cylinder is mounted on the sleeve 5. The movable plate is mounted on the movable cylinder. The feed hopper 2 is mounted on the movable plate.

[0021] In this embodiment, the mounting bracket 1 provides the installation conditions for the closing mechanism. Material can be fed into the injection molding machine through the feed hopper 2. After feeding the injection molding machine, the turntable 3 is rotated, causing the screw 4 to rotate. The screw 4 causes the sleeve 5 to move closer to the turntable 3. The sleeve 5 causes the moving cylinder to move closer to the turntable 3. The moving cylinder causes the feed hopper 2 on the moving plate to move until the feed hopper 2 moves to a preset position. The moving plate then closes the feed port on the mounting bracket 1, preventing impurities from entering the injection molding machine. This solves the problem that external impurities may enter the injection molding machine through the feed hopper during the injection molding of the wheel arch frame, leading to a decrease in the quality of the injection-molded rear wheel arch frame.

[0022] Furthermore, the movable cylinder includes a cylinder body 6, a slide rail 7, and a slider 8. The cylinder body 6 is fixedly connected to the sleeve 5 and is located on one side of the sleeve 5. The slide rail 7 is fixedly connected to the mounting bracket 1 and is located inside the mounting bracket 1. The slider 8 is slidably connected to the slide rail 7 and is fixedly connected to the cylinder body 6.

[0023] In this embodiment, the movement of the cylinder 6 can drive the movement of the plate 9. The slide rail 7 provides installation conditions for the slider 8. The slider 8 can guide and limit the movement of the cylinder 6, thereby improving the stability of the cylinder 6 during movement.

[0024] Furthermore, the movable plate includes a plate body 9, a rotating component, and a supporting plate 11. The plate body 9 is fixedly connected to the cylinder 6 and is located on one side of the cylinder 6. The rotating component is installed on one side of the plate body 9, and the supporting plate 11 is installed on the rotating component.

[0025] In this embodiment, the plate 9 provides installation conditions for the rotating component, which can drive the supporting plate 11 to move. The plate 9, in conjunction with the supporting plate 11, can install the feed hopper 2.

[0026] Furthermore, the rotating component includes a rotating rod 12, a knob 13, a horizontal plate 14, and a guide rod 15. The rotating rod 12 is threadedly connected to the plate body 9 and is located on one side of the plate body 9. The knob 13 is fixedly connected to the rotating rod 12 and is located on the rotating rod 12. The horizontal plate 14 is rotatably connected to the rotating rod 12 and fixedly connected to the abutment plate 11. The guide rod 15 is fixedly connected to the horizontal plate 14 and slidably connected to the plate body 9, and passes through the plate body 9.

[0027] In this embodiment, the knob 13 can rotate the rotating rod 12, which in turn can move the horizontal plate 14, and the movement of the horizontal plate 14 can move the supporting plate 11. The guide rod 15 can guide and limit the horizontal plate 14.

[0028] Furthermore, the closing mechanism also includes a locking block 16 and a return spring 17. The locking block 16 is slidably connected to the mounting frame 1 and passes through the mounting frame 1. The return spring 17 is fixedly connected to the locking block 16 and the mounting frame 1, and is located between the locking block 16 and the mounting frame 1.

[0029] In this embodiment, the turntable 3 has multiple mating holes. The locking block 16 can limit the turntable 3 by cooperating with the corresponding mating hole. The locking block 16 can be pushed into the corresponding mating hole by the rebound force of the reset spring 17.

[0030] After feeding the injection molding machine, the turntable 3 is rotated, which drives the screw 4 to rotate. The screw 4 drives the sleeve 5 to move closer to the turntable 3. The sleeve 5 drives the cylinder 6 to move closer to the turntable 3. The cylinder 6 drives the feed hopper 2 on the plate 9 to move until the feed hopper 2 moves to the preset position. The plate 9 then closes the feed port on the mounting bracket 1, thus preventing impurities from entering the injection molding machine. This solves the problem that when injection molding wheel arch rims, external impurities may enter the injection molding machine through the feed hopper, leading to a decrease in the quality of the injection molded rear wheel arch rim.

[0031] Secondly, a rear wheel arch frame, employing the injection feeding mechanism of the rear wheel arch frame described in the first aspect, wherein the rear wheel arch frame is injection molded using the injection feeding mechanism of the rear wheel arch frame.
