[0025] Reference Figure 1 As shown, this utility model provides a technical solution: a handle cover injection mold, including a base 1, a collection box 7 installed inside the base 1, two first electric telescopic rods 2 and a second electric telescopic rod 3 fixedly connected to the upper surface of the base 1, connecting plates 4 fixedly connected to the sides of the two first electric telescopic rods 2, and the sides of the two connecting plates 4 away from the first electric telescopic rods 2 fixedly connected to the second electric telescopic rods 3, an upper mold 6 fixedly connected to the output ends of the two first electric telescopic rods 2 and the second electric telescopic rods 3, a lower mold 5 rotatably connected between the two connecting plates 4, a feeding device 8 provided on the side of the base 1, and a buffer device 9 provided on the surface of the base 1.

[0026] The specific settings and functions of the feeding device 8 and the buffer device 9 will be explained in detail below.

[0027] Reference Figure 1 and Figure 2 as well as Figure 3 As shown in this embodiment: the feeding device 8 includes two "L"-shaped plates 81, both of which are fixedly connected to the side of the base 1. Sliding rods 82 are slidably connected to the inner walls of both "L"-shaped plates 81. A horizontal plate 83 is fixedly connected to the end of the sliding rod 82 near the lower mold 5, and several rubber pillars 84 are fixedly connected to the side of the horizontal plate 83 away from the sliding rod 82. After the injection molding of the handle cover is completed, the rubber pillars 84 can be controlled to approach the lower mold 5 via the sliding rod 82 and the horizontal plate 83, striking it to promote the separation of the handle cover from it. A drive plate 85 is fixedly connected to the end of the sliding rod 82 away from the horizontal plate 83, and a drive screw 88 is threaded into the inner wall of the drive plate 85. The drive screw 88 controls the movement of the drive plate 85, thereby using the drive plate 85 to move the sliding rod 82.

[0028] A drive motor 87 is mounted on the side of the drive plate 85 away from the "L"-shaped plate 81, and the output end of the drive motor 87 is fixedly connected to the drive screw 88. The drive motor 87 can control the rotation of the drive screw 88. A stabilizing plate 89 is rotatably connected to the end of the drive screw 88 away from the drive motor 87. Both sides of the stabilizing plate 89 are fixedly connected to the "L"-shaped plates 81, and the stabilizing plate 89 is installed between the two "L"-shaped plates 81. A mounting bracket 86 is fixedly connected to the side of the stabilizing plate 89 away from the lower mold 5. The mounting bracket 86 is driven by the drive motor 87 and slidably connected to the inner wall of the drive plate 85. The stabilizing plate 89 improves the stability of the drive screw 88 during installation and rotation, and the mounting bracket 86 ensures the stable installation of the drive motor 87.

[0029] Reference Figure 1 and Figure 2 as well as Figure 4 and Figure 5 As shown, specifically, the buffer device 9 includes a first slider 91. A first groove is provided on the side of the base 1. The first slider 91 is slidably connected to the surface of the first groove on the base 1. A mounting plate 92 is fixedly connected to the side of the first slider 91. The mounting plate 92 is slidably connected to the surface of the base 1. Two movable plates 93 are slidably connected to the surface of the mounting plate 92. An inclined plate 94 is fixedly connected to the side of the two movable plates 93 that are close to each other. Through the inclined plate 94 and the mounting plate 92, the handle cover can be buffered during the fall, minimizing the risk of damage due to impact.

[0030] Two second sliding grooves are formed on the surface of the mounting plate 92. Second sliders 95 are slidably connected to the surfaces of the second sliding grooves on both mounting plates 92. The second sliders 95 are fixedly connected to the moving plate 93. A fixing rod 96 is slidably connected to the inner wall of the second slider 95, and the fixing rod 96 is fixedly connected to the surface of the second sliding groove on the mounting plate 92. By using the second sliders 95, a stable connection between the moving plate 93 and the mounting plate 92 can be maintained while allowing the moving plate 93 to move relative to the mounting plate 92. A spring 97 is fitted onto the surface of the fixing rod 96, and both ends of the spring 97 are fixedly connected to the second slider 95 and the mounting plate 92, respectively. The fixing rod limits the offset of the spring 97 and restricts the position of the second slider 95.

[0031] Working principle: When using the injection mold to produce the handle cover, the first electric telescopic rod 2 and the second electric telescopic rod 3 are activated first, causing the upper mold 6 to move closer to the lower mold 5. Then, the injection molding material is injected between the upper mold 6 and the lower mold 5. After the injection molding of the handle cover is completed, the first electric telescopic rod 2 and the second electric telescopic rod 3 control the upper mold 6 to move away from the lower mold 5. Then, the lower mold 5 is controlled to rotate between the two connecting plates 4. After that, the drive motor 87 on the mounting frame 86 is activated, which controls the drive screw 88 to rotate on the inner wall of the drive plate 85 and the surface of the stabilizing plate 89. Thus, the drive plate 85 controls the horizontal plate 83 and the rubber column 84 to move closer to the lower mold 5 through the slide rod 82. The drive plate 85 approaches the "L"-shaped plate 81, promoting the separation of the handle cover inside the lower mold 5 from it, completing the unloading of the handle cover. With the feeding device 8, after the handle cover is produced by injection molding, the rubber column 84 is controlled by the horizontal plate 83 to strike the lower mold 5, thereby promoting the separation of the handle cover from the lower mold 5 and improving the stability of the finished handle cover feeding.

[0032] As the handle cover detaches from the lower mold 5 and approaches the collection box 7 under gravity, it comes into contact with the inclined plate 94 and the mounting plate 92. Simultaneously, under gravity, the handle cover presses against the inclined plate 94, causing the inclined plate 94 to move the moving plate 93 and the second slider 95. This allows the handle cover to slide between the inclined plate 94 and the mounting plate 92 and fall into the collection box 7. Then, under the force of the spring 97, the second slider 95 slides on the surface of the fixed rod 96, causing the inclined plate 94 to move closer to the upper mold 6. When it is necessary to separate the collection box 7 from the base 1, the mounting plate 92 is controlled to move the first slider 91 on the surface of the first groove on the base 1, causing the inclined plate 94 and the mounting plate 92 to move closer to the upper mold 6, thus facilitating the disassembly of the collection box 7. The buffer device 9, when the handle cover detaches from the lower mold 5 and falls into the collection box 7, provides a cushioning effect, minimizing the risk of damage from impacts during the fall.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
