The present invention provides an injection molded part for a deflector, which is used to be cut to obtain deflectors of different specifications.

In the embodiment of the present invention, as shown in FIG. 1 , the baffle injection part includes a first injection part 100 and a second injection part 200 formed on the first injection part 100 . Wherein, the first injection part 100 corresponds to the installation structure of the molding deflector, and the second injection part 200 includes a base plate 240 and a plurality of cutting structures 210 . A plurality of cutting structures 210 are sequentially arranged on the substrate 240 at intervals, and the cutting structures 210 are protruded or recessed on the substrate 240 . The cutting structure 210 is used for cutting to form the mating end of the deflector and the counterpart.

It can be understood that the function of the deflector is to guide the movement direction of the fluid (gaseous fluid or liquid fluid) to increase the work of the product. Taking the air deflector of the air conditioner as an example, it is usually arranged at the air outlet of the air conditioner to guide the airflow direction at the air outlet of the air conditioner, so as to improve the user experience. Taking the upper air deflector of the car as an example, it can cooperate with the front bumper of the car to play the role of sealing and guiding the air during the driving process of the car, thereby reducing the noise and wind resistance during the driving process of the car. It can be seen that the deflector is not a separate part in the product and needs to be used in conjunction with the product. Then, the installation structure corresponding to the deflector formed by the first injection part 100 can be regarded as the part corresponding to the final cut-and-formed target deflector, which is fixedly or movably matched with the product. Since the installation structures of different baffles, such as studs, screws, threaded holes, etc., are also changed according to different practical applications, the specific structure of the first injection part 100 is not limited in the present application. Specifically, the deflector can be movably installed on the product, or it can be inmovably installed on the product. In this embodiment, the structures or components used to match with the deflector in the product may be collectively referred to as counterparts.

In this application, different baffles are obtained by cutting the injection baffles in different cutting ways, so there is a common structure among different baffles. The second injection molding part 200 is used for cutting, so that the specifications and details of the baffles are different, so as to obtain different baffles. Since these baffles are ultimately cut, there must be dimensional variations between different baffles. And the size of the baffle injection part must meet the maximum size of each baffle. By arranging the plurality of cutting structures 210 on the base plate 240 at intervals, the change of the deflector from the largest size to the smallest size can be adapted to obtain deflectors of different sizes. The cutting structure 210 can also be used as a cutting mark on the second injection molding part 200 to facilitate the staff to cut the injection molding of the baffle. Since the cutting structure 210 is raised or recessed to protrude on the base plate 240, and during cutting, the cutting structure 210 is cut to form the mating end of the deflector and the counterpart, so the extension direction of the mating end of the final deflector is also It is opposite to the extension direction of the base plate 240 , so that when the deflector is matched with the counterpart, the counterpart end is easily deformed, and it is easy to interfere with the counterpart.

Since the existing mold can only inject a specific deflector, the deflector can only be used with a specific product, but cannot be adapted to other products. Even if the structure of the baffles of multiple products is generally similar, the different baffles cannot be used interchangeably. That is, the existing baffles have poor compatibility, resulting in different molds for manufacturing different baffles, and the production cost remains high. For the deflector injection molded part provided by the present application, a plurality of cutting structures 210 are arranged on the second injection part, so that after the deflector injection molded part is cut, different deflectors can be obtained to suit different products. Strong compatibility. In this way, in the production of multiple baffles with similar structures, the design of the mold is reduced, and the production cost is greatly reduced.

Furthermore, due to the characteristics of plastics, and the baffles are mostly sheet-like structures, the baffles usually have different degrees of deformability. Through this deformation ability, the interference fit between the deflector and the counterpart can theoretically be achieved. However, the mating end of the existing deflector that mates with the counterpart extends linearly. When there is an interference fit with the opponent piece, the mating end of the deflector is not easily deformed, and the staff needs to apply greater pressure to deform the overall deflector, so that the interference fit between the deflector and the opponent piece can be achieved. In this way, not only there is a certain degree of difficulty in operation, but also after the overall deformation of the deflector, it is easy to have a certain degree of influence on the deflector and the strength of the deflector, which is not conducive to the work of the product. With the technical solution of the present application, since the cutting structure 210 is raised or recessed to protrude on the base plate 240 , the extension direction of the opposite end of the deflector is different from the extension direction of the base plate 240 . The pressure exerted on the guide plate of the piece is opposite to the extension direction of the opposite end of the guide plate, and the opposite end of the guide plate is easily deformed, while the whole of the guide plate hardly deforms. It can be seen that, compared with the prior art, the deflector injection molded part of the present application also has the advantages of facilitating the interference fit between the deflector and the counterpart, and improving the tightness of the deflector and the counterpart. It should be noted that, in the present application, the substrate 240 is arranged smoothly, and its surface is a smooth arc or straight surface, and the cutting structure 210 is raised or recessed relative to the plane or arc, and is protruded on the substrate 240 .

Of course, the design of the present application is not limited to this, and in some cases, a tight fit or a clearance fit can also be provided between the deflector and the counterpart. When the deflector is closely matched with the counterpart, the mating end that is opposite to the extension direction of the base plate 240 can improve the tightness of the deflector and the counterpart, thereby improving the tightness of the deflector and the counterpart. When the deflector is clearance-fitted with the opponent piece, the paired end of the deflector can be used as a mark to improve the recognition of the gap between the deflector and the opponent piece, and facilitate the operation and inspection of the staff.

Specifically, in this embodiment, the air deflector injection molded part is an automotive air deflector injection molded part, and is injection molded through a single-cavity two-color molding process, and the first injection part 100 of the air deflector injection molded part is injection molded from a hard rubber material , the second injection part 200 is injection-molded by soft rubber material. Of course, the design of the present application is not limited to this, and in other embodiments of the present application, the air deflector may also be an injection molded part of other air deflectors such as an air-conditioning air deflector injection molded part. Moreover, the material of the first injection part 100 and/or the second injection part 200 can also be made of soft rubber and/or hard rubber. The specific setting can be selected according to the actual usage.

Referring to FIG. 1 and FIG. 2 , the cutting structure 210 includes a first cutting structure 211 , and the first cutting structure 211 is disposed on the edge of the second injection part 200 on the side away from the first injection part 100 . It can be understood that, since the counterpart end of the deflector can be obtained after the cutting structure 210 is cut, the first cutting structure 211 can be directly arranged on the edge of the second injection molding part 200 away from the first injection molding part 100 after cutting the first cutting structure 211 Get the largest size deflector. In this way, the materials used for the injection molded parts of the deflector can be reduced as much as possible on the premise of satisfying the tightness of the deflector and the counterpart, so as to reduce the cost.

Referring to FIG. 3 , after the first cutting structure 211 is disposed on the edge of the substrate 240 , this embodiment further proposes that the first cutting structure 211 extends in an arc shape from the substrate 240 to the direction away from the first injection part 100 . After the first cutting structure 211 is cut, a counterpart end of the air guide plate will be formed, and the counterpart end of the air guide plate will be deformed when matched with the counterpart. The first cutting structure 211 is set in an arc shape, and after the first cutting structure 211 is partially cut, it can still maintain a certain arc, which is beneficial to the deformation of the paired end of the deflector, so as to facilitate the connection between the deflector and the counterpart. between the assembly. In addition, the mating end of the arc-shaped deflector is more closely attached to the counterpart after being deformed, which is beneficial to improve the tightness of the fit between the deflector and the counterpart. Of course, the design of the present application is not limited to this, and in other embodiments of the present application, the first cutting structure 211 may also extend in a straight line, or extend in a wave shape, or the like.

Please continue to refer to FIG. 2 , the first cutting structure 211 is gradually thickened from the end side away from the substrate 240 toward the direction of the substrate 240 . Since the first cutting structure 211 is formed on the edge of the substrate 240 away from the first injection molding part 100 , and after the first cutting structure 211 is cut, it is used to cooperate with the counterpart and does not play a role in guiding the flow. Therefore, the first cutting structure 211 is 211 is gradually thickened, which can reduce the structural strength of the first cutting structure 211, so as to facilitate the deformation of the first cutting structure 211, thereby reducing the difficulty of matching the deflector with the counterpart. In addition, the gradual thickness setting of the first cutting structure 211 can also save the materials used for the injection molding parts of the deflector to a certain extent, thereby reducing the cost. In other embodiments of the present application, the first cutting structure 211 may also be set to have a uniform thickness.

Referring to FIG. 1 and FIG. 2 , in this embodiment, the cutting structure 210 further includes a second cutting structure 212 , and the second cutting structure 212 is disposed on the side of the first cutting structure 211 close to the first injection molding part 100 . , and extends in an arc. Taking the first injection molding part 100 as a reference, the second cutting structure 212 is located inside the first cutting structure 211 . Obviously, by cutting the second cutting structure 212, a baffle with a relatively small size can be obtained. The purpose of setting the first cutting structure 211 to be arc-shaped is the same as the purpose of setting the second cutting structure 212 to be arc-shaped. tightness. Meanwhile, in the guide plate where the second cutting structure 212 is not cut, since the second cutting structure 212 is arranged in an arc shape, its surface shape is also conducive to the passage of fluid, so as to improve the guide function of the guide plate. Of course, in other embodiments of the present application, the second cutting structure 212 may also be configured to extend in a straight line, a wave shape, or the like.

Preferably, the arc of the second cutting structure 212 is greater than the arc of the first cutting structure 211 . It can be seen from the above content that the second cutting structure 212 is disposed inside the first cutting structure 211 , then, different from the first cutting structure 211 , the second cutting structure 212 also has the function of supporting the deflector before being cut. Therefore, setting the radian of the second cutting structure 212 to be larger than that of the first cutting structure 211 can increase the structural strength of the second cutting structure 212 to improve the structural strength of the deflector. Moreover, unlike the thickness of the first cutting structure 211 being set to gradually increase from the end side away from the second injection molding part 200 to the direction of the second injection molding part 200 , in order to ensure the structural strength of the baffle, the thickness of the second cutting structure 212 Set evenly. Certainly, on the premise that the structural strength of the deflector is sufficient, in some embodiments of the present application, the radian of the second cutting structure 212 can also be equal to or smaller than the radian of the first cutting structure 211, and the thickness thereof can also vary.

As shown in FIG. 1 and FIG. 2 , the substrate 240 includes a first connecting board 220 and a second connecting board 230 . The first connecting plate 220 is connected between the first cutting structure 211 and the second cutting structure 212, the second connecting plate 230 is connected between the second cutting structure 212 and the first injection part 100, and the second connecting plate 230 is connected The board 230 is stacked with the first connection board 220 . Since the first cutting structure 211 and the second cutting structure 212 are both arranged in an arc shape, and the first connecting plate 220 and the second connecting plate 230 are arranged in layers, it can be understood that the first cutting structure 211 and the second cutting structure The arc center direction of 212 is located on the same side of the second injection part 200 . In this way, the structural design of the injection molded part of the deflector can be simplified, and the deformability of the deflector can be enhanced, so that the deflector is not easily damaged. At the same time, the stacked arrangement of the first connecting plate 220 and the second connecting plate 230 also has a certain position avoidance effect, so as to facilitate the installation of the deflector in the product. Of course, in other embodiments of the present application, when both the first cutting structure 211 and the second cutting structure 212 are set to be arc-shaped, the arc centers of the first cutting structure 211 and the second cutting structure 212 may also be located at the second Both sides of the injection molding part 200 .

Referring to FIG. 1 and FIG. 2 , the cutting structure 210 further includes a third cutting structure 213 . The third cutting structure 213 is disposed on the side of the second cutting structure 212 close to the first injection part 100 and protrudes from the substrate. 240. Taking the first injection molding part 100 as a reference, the third cutting structure 213 is located on the inner side of the second cutting structure 212 . Obviously, a smaller size baffle can be obtained by cutting the third cutting structure 213 . Specifically, in this embodiment, the third cutting structure 213 is protruded on the second connecting plate 230 . Setting the third cutting structure 213 to protrude on the base plate 240 can enhance the structural strength of the second injection molding part 200 compared with a flat plate surface, thereby enhancing the structural strength of the deflector. In addition, the third cutting structure 213 can also form an obvious cutting mark on the second injection molding part 200 to facilitate the user's operation.

Preferably, the second connecting plate 230 defines a groove corresponding to the third cutting structure 213 . In this way, the thickness of the deflector at the third cutting structure 213 can be made more uniform, which is beneficial to the injection molding of the second injection part 200 .

2 and 3, the third cutting structure 213 includes a first inclined section 213a, a second inclined section 213b and a connecting section 213c. The connecting section 213c is connected between the first inclined section 213a and the second inclined section 213b, and is disposed parallel to the second connecting plate 230; the first inclined section 213a extends obliquely from the second cutting structure 212 to the connecting plate 213c , the second inclined section 213b extends from the connecting section 213c to the direction of the first injection part 100 inclinedly. Setting the third cutting structure 213 as a three-section structure can simplify the structural design of the third cutting structure 213 and facilitate the formation of the third cutting structure 213 . It is worth noting that, in this embodiment, since the air deflector injection molded part is an automobile air deflector injection molded part, the third cutting structure 213 can be used not only to be cut, but also to cooperate with other parts of the car to locate or fixed deflectors.

It should be noted that the design of the present application is not limited to only setting three cutting structures 210 on the second injection molding part 200. According to different actual needs, the second injection molding part 200 can also be provided with one, two, four, Five or more cutting structures 210 .

Referring to FIG. 2 , in this embodiment, the third cutting structure 213 is protruded on the second connecting plate 230 , with the third cutting structure 213 as the limit, in order to facilitate the installation of the vehicle air deflector, the second connecting plate The 230 has an escape concave surface formed on the side away from the third cutting structure 213 , and the escape concave surface is located on the side of the third cutting structure 213 close to the first injection part 100 .

The present invention also provides an injection mold for a deflector, which is used to prepare an injection mold for a deflector. The specific structure of the deflector injection molded part refers to the above-mentioned embodiments. Since the deflector injection molded part prepared by the deflector injection mold adopts all the technical solutions of all the above-mentioned deflector injection molded parts, it has at least the above-mentioned implementation.

Under the inventive concept of the present invention, the equivalent structural transformations made by the contents of the description and drawings of the present invention, or the direct/indirect application Other related technical fields are included in the scope of patent protection of the present invention.
