Description

Technical Field

[0001] This utility model relates to the field of automotive wheel cover processing technology, specifically an injection mold for automotive wheel cover processing. Background Technology

[0002] Wheel arch covers, also known as wheel well covers or fenders, are important components installed above the four wheels of a motor vehicle. During vehicle operation, the tires directly contact the ground, generating friction and causing the wheels to rotate. Wheel arch covers prevent dirt, stones, and other debris from splashing onto other parts of the vehicle body, thus reducing scratches and stains and protecting the paint. They also effectively reduce noise from tire-to-ground friction and impacts from stones, providing a quieter and more comfortable driving environment for the driver and passengers.

[0003] Injection molds are required in the processing of automotive wheel covers. Chinese utility model patent CN219926820U discloses an injection mold for automotive wheel coveres, relating to the field of automotive wheel cover injection mold technology. It includes an injection top plate, with an injection molding machine fixedly installed through its center. Support columns are fixedly connected to the four corners of the lower surface of the injection top plate. An injection plate and an injection base are movably connected to the injection top plate via the support columns. The injection base has a cavity containing a demolding device. The demolding device includes a demolding cavity inside the injection base, with motor cavities on both sides of the upper wall of the demolding cavity. This utility model uses a motor to drive a worm gear and worm wheel to rotate, causing a rotating block to rotate. The rotating block continuously presses the linkage plate downwards, thus pushing the demolding top plate against the injection groove by a telescopic spring to complete demolding. This achieves rapid demolding after injection molding, solving the problem of waiting for natural demolding after injection molding in existing technologies, which is time-consuming.

[0004] However, while the demolding top plate can achieve the demolding effect during use, the mold should be sealed during injection molding. The demolding top plate results in poor sealing of the entire mold, causing the injected plastic to enter the gaps, affecting the molding effect and failing to meet production requirements. Therefore, an injection mold for processing automotive wheel covers is proposed to solve the problems mentioned above. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an injection mold for processing automotive wheel covers, which has the advantage of good sealing performance. It solves the problem that while existing injection molds can achieve demolding with a release plate, the mold should be sealed during injection molding. The release plate results in poor sealing of the entire mold, causing the injected plastic to enter the gaps and affecting the molding effect.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an injection mold for processing automobile wheel covers, comprising a mounting base and a lower mold base fixedly connected to the top of the mounting base, wherein a top plate is provided on the top of the mounting base, and a cooling and forming structure is provided between the top plate and the lower mold base;

[0007] The cooling and forming structure includes an upper mold base fixedly installed on the top plate near the lower mold base. An upper mold is fixedly connected to the upper mold base near the lower mold base. Cooling cavities are provided inside both the upper mold and the lower mold base. A liquid inlet pipe communicating with the cooling cavity is fixedly connected to the front of the upper mold base. A lower mold groove adapted to the upper mold is provided on the upper surface of the lower mold base.

[0008] Furthermore, the shapes of the two cooling cavities are respectively adapted to the shapes of the upper mold and the lower mold groove, and the back of the upper mold base is fixedly connected to a liquid outlet pipe that communicates with the cooling cavity.

[0009] Furthermore, a mounting bracket is slidably connected inside the lower mold base, and a filter cylinder extending to its bottom is fixedly installed on the top of the mounting bracket. A connecting pipe communicating with the cooling cavity is fixedly connected to the front of the lower mold base.

[0010] Furthermore, positioning blocks extending into the lower mold base are fixedly connected to both the left and right sides of the mounting bracket, and positioning grooves that match the positioning blocks are provided on the inner wall of the lower mold base.

[0011] Furthermore, the top of the top plate is fixedly connected to an injection pipe extending into it, and the interior of both the upper mold base and the upper mold is provided with an injection channel that communicates with the injection pipe.

[0012] Furthermore, a positioning guide rod penetrating the top plate is fixedly connected to the upper surface of the lower mold base. A rotating handle is provided at the top end of the positioning guide rod, and a threaded block that is threadedly connected to the positioning guide rod is fixedly connected to the bottom of the rotating handle.

[0013] Furthermore, the positioning guide rod is connected to the top plate by a sliding connection, and there are four positioning guide rods.

[0014] Furthermore, the mounting base has four mounting holes inside, which are evenly distributed at the four corners of the mounting base.

[0015] Compared with the prior art, this utility model provides an injection mold for processing automobile wheel covers, which has the following beneficial effects:

[0016] 1. This injection mold for processing automotive wheel covers features two cooling chambers, which can cool the upper mold and lower mold groove separately, resulting in uniform cooling of the plastic material between the upper mold and lower mold groove. This improves cooling efficiency and speeds up the injection molding process. Additionally, the inclusion of inlet and outlet pipes allows the coolant to flow within the cooling chambers, further enhancing the cooling effect. Furthermore, the inclusion of a filter cartridge filters the coolant, preventing impurities from entering the cooling chambers and ensuring their cleanliness.

[0017] 2. This injection mold for processing automotive wheel covers, by setting injection pipes and channels, can achieve uniform injection, ensuring a more uniform thickness and better molding effect for the molded wheel cover. Simultaneously, it accelerates cooling, allowing for faster removal of the molded wheel cover. This achieves rapid demolding without affecting the overall sealing environment. It solves the problem that while demolding with a release plate can achieve demolding, the mold should be sealed during injection molding; a release plate would result in poor sealing, causing injected plastic to enter gaps and affecting the molding effect.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1 to 3This embodiment of an injection mold for processing automotive wheel covers includes a mounting base 1 and a lower mold base 2 fixedly connected to the top of the mounting base 1. A top plate 3 is provided on the top of the mounting base 1. A cooling and forming structure is provided between the top plate 3 and the lower mold base 2. The cooling and forming structure includes an upper mold base 4 fixedly installed on the side of the top plate 3 near the lower mold base 2. An upper mold 5 is fixedly connected to the side of the upper mold base 4 near the lower mold base 2. Cooling cavities 8 are provided inside both the upper mold 5 and the lower mold base 2. A liquid inlet pipe 6 connected to the cooling cavity 8 is fixedly connected to the front of the upper mold base 4. A lower mold groove 7 adapted to the upper mold 5 is provided on the upper surface of the lower mold base 2.

[0024] Specifically, the shapes of the two cooling chambers 8 are adapted to the shapes of the upper mold 5 and the lower mold groove 7, respectively. The back of the upper mold base 4 is fixedly connected to the liquid outlet pipe that communicates with the cooling chamber 8. The lower mold base 2 is slidably connected to the mounting bracket 9. The top of the mounting bracket 9 is fixedly installed with a filter cylinder 10 that extends to its bottom. The front of the lower mold base 2 is fixedly connected to the connecting pipe 11 that communicates with the cooling chamber 8.

[0025] It should be noted that positioning blocks extending into the lower mold base 2 are fixedly connected to both the left and right sides of the mounting bracket 9, and positioning grooves that match the positioning blocks are provided on the inner wall of the lower mold base 2.

[0026] It should be noted that by setting two cooling chambers 8, the upper mold 5 and the lower mold groove 7 can be cooled separately, thereby making the injection plastic between the upper mold 5 and the lower mold groove 7 cool evenly, improving the cooling efficiency and speeding up the injection molding speed. At the same time, by setting the liquid inlet pipe 6 and the liquid outlet pipe, the coolant can flow inside the cooling chamber 8, thereby improving the cooling effect.

[0027] Please see Figure 1 and Figure 3 In this embodiment, the top of the top plate 3 is fixedly connected to an injection pipe 12 extending into it, and the upper mold base 4 and the upper mold 5 are both provided with injection channels 13 that communicate with the injection pipe 12.

[0028] Specifically, by setting the injection pipe 12 and injection channel 13, a uniform injection effect can be achieved, ensuring that the thickness of the molded car wheel cover is more uniform and the molding effect is better. At the same time, the cooling speed can be accelerated to remove the molded car wheel cover more quickly, achieving a rapid demolding effect without affecting the overall sealing environment.

[0029] Please see Figure 1 and Figure 2In this embodiment, a positioning guide rod 14 that penetrates the top plate 3 is fixedly connected to the upper surface of the lower mold base 2. A rotating handle 15 is provided at the top of the positioning guide rod 14. A threaded block 16 that is threadedly connected to the bottom of the rotating handle 15 is fixedly connected to the positioning guide rod 14. The positioning guide rod 14 is connected to the top plate 3 by sliding connection. There are four positioning guide rods 14.

[0030] Specifically, the mounting base 1 has four mounting holes 17 inside, which are evenly distributed at the four corners of the mounting base 1.

[0031] The working principle of the above embodiments is as follows:

[0032] First, the staff fixes the device in a suitable position using the mounting base 1. Then, the top plate 3 is moved downwards by the hydraulic cylinder until the upper mold 5 and the lower mold groove 7 are aligned. At this time, the staff delivers the injection plastic through the injection pipe 12 to the space between the upper mold 5 and the lower mold groove 7. Then, the coolant is delivered to the cooling chamber 8. The coolant is then filtered by the filter cartridge 10. After cooling and molding, the hydraulic cylinder moves the top plate 3 upwards, and the staff can then remove the molded car wheel cover.

[0033] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods, and any method that can achieve its beneficial effects can be implemented.
