The utility model provides a guide plate injection molding for be cut in order to obtain the guide plate of different specifications.

In the embodiment of the present invention, as shown in fig. 1, the injection-molded component of the guide plate includes a first injection-molded portion 100 and a second injection-molded portion 200 formed on the first injection-molded portion 100. The first injection molding part 100 corresponds to a mounting structure for forming a baffle, and the second injection molding part 200 includes a substrate 240 and a plurality of cutting structures 210. The plurality of cutting structures 210 are sequentially disposed 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 a mating end for the deflector to mate with the counterpart member.

It will be appreciated that the role of the baffles is to direct the direction of movement of the fluid (gaseous or liquid) to gain the operation of the product. Taking the air deflector of the air conditioner as an example, the air deflector is generally arranged at the air outlet of the air conditioner and used for guiding the airflow direction at the air outlet of the air conditioner so as to improve the user experience. And taking the guide plate on the automobile as an example, the guide plate can be matched with a front bumper of the automobile to play a role in sealing and guiding the flow in the driving process of the automobile, so that the noise and the wind resistance in the driving process of the automobile are reduced. It can be seen that the baffle is not a separate component in the product and needs to be used with the product. The first injection molding part 100 corresponding to the installation structure forming the baffle can be regarded as the final cut and formed target baffle corresponding to the structure fixedly matched/movably matched with the product. Because the mounting structure of different guide plates also can change along with according to practical application's difference, like double-screw bolt, screw rod, screw hole etc. therefore this application does not do the restriction to the concrete structure of first portion of moulding plastics 100. Specifically, the deflector is movably mounted on the product, and may not be movably mounted on the product. In the present embodiment, the structure or the component of the product for matching with the baffle can be collectively referred to as the opponent.

In the present application, different baffles are obtained by cutting the baffle injection-molded part in different cutting ways, so that there is a common structure between different baffles. The second injection molding part 200 is used for cutting, so that the specifications and the details of the guide plate are different, and different guide plates can be obtained. Since these baffles are eventually cut, there must be a variation in size between different baffles. And the size of the guide plate injection molding must satisfy the maximum size of each guide plate. By sequentially spacing a plurality of cutting structures 210 on the substrate 240, the diversion plate can be adapted to change from the maximum size to the minimum size, so as to obtain diversion plates with different size specifications. The cutting structure 210 can also be used as a cutting mark on the second injection molding part 200, so that a worker can conveniently cut the guide plate injection molding piece. Because the cutting structure 210 is protruded or recessed on the substrate 240, and when cutting, the cutting structure 210 is cut to form a mating end of the flow guide plate mating with the counterpart member, so that the extending direction of the mating end of the flow guide plate is also staggered with the extending direction of the substrate 240, so that when the flow guide plate is mating with the counterpart member, the mating end of the flow guide plate is easily deformed, and is easily in interference fit with the counterpart member.

Because the existing mold can only inject a certain specific guide plate, the guide plate can only be matched with a certain specific product for use, but can not be matched with other products. Even if the structures of the guide plates of a plurality of products are basically similar, different guide plates cannot be used alternatively. That is, the conventional guide plate has poor compatibility, so that different molds are required for manufacturing different guide plates, and the production cost is high. The application provides a guide plate injection molding through set up a plurality of cutting structures 210 in the second portion of moulding plastics for the guide plate injection molding is cut the back, can obtain different guide plates, in order to adapt to different products, and the commonality is strong. Like this, produce a plurality of guide plates that the structure is similar and be, reduced the design of mould, greatly reduced manufacturing cost.

It should be noted that, due to the characteristics of plastics, the baffle is mostly a sheet structure, so the baffle usually has different degrees of deformability. Through this kind of deformability, can realize guide plate and the interference fit of opponent's piece in theory. However, the mating end of the existing deflector with the counter-element is linearly extended. When with opponent's piece interference fit, the counterpoint end non-deformable of guide plate needs the staff to apply great pressure to make the whole deformation that takes place of guide plate, just can realize guide plate and opponent's interference fit. Like this, not only have certain degree of difficulty in the operation, and the whole deformation back of guide plate, cause the influence to a certain extent to the water conservancy diversion fruit and the intensity of guide plate easily, be unfavorable for the work of product. And through the technical scheme of this application, because cutting structure 210 is protruding or sunken and protruding locate base plate 240 on for the extending direction of guide plate counterpoint is mutually wrong with the extending direction of base plate 240, consequently when with counterpoint interference fit, to the pressure that the guide plate was applyed to the adversary spare and the extending direction of guide plate counterpoint mutually wrong, the guide plate counterpoint easily takes place to deform, and the whole of guide plate then can hardly take place to deform. It is thus clear that, compare with prior art, the guide plate injection molding of this application still has the interference fit who is convenient for realize guide plate and adversary's piece, improves the advantage of guide plate and adversary's piece complex compactness. It should be noted that, in the present application, the substrate 240 is disposed smoothly, and the surface thereof is a smooth curved surface or a straight surface, and the cutting structure 210 is raised or recessed relative to the plane or the curved surface and is disposed on the substrate 240 in a protruding manner.

Of course, the design of the present application is not so limited, and in some cases, there may be a close or clearance fit between the baffle and the opposing member. When the guide plate is closely matched with the counterpart member, the mating end which is staggered with the extending direction of the substrate 240 can improve the close degree of the fit between the guide plate and the counterpart member, so that the matching tightness between the guide plate and the counterpart member is improved. When the guide plate is in clearance fit with the opponent piece, the opposite end of the guide plate can be used as an identifier, so that the identification degree of the clearance between the guide plate and the opponent piece is improved, and the operation and the inspection of a worker are facilitated.

Specifically, in this embodiment, this guide plate injection molding is car guide plate injection molding, and through single chamber double-colored forming process injection moulding, the first portion of moulding plastics 100 of guide plate injection molding is ebonite material injection moulding, and the second portion of moulding plastics 200 is by the injection moulding of flexible glue material. Of course, the design of this application is not limited to this, and in other embodiments of this application, this guide plate also can be the injection molding of other guide plates such as air conditioner guide plate injection molding. The material of the first injection molding part 100 and/or the second injection molding part 200 can also be made of soft glue and/or hard glue by injection molding, and how to set the material can be selected according to different actual use conditions.

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 an edge of the second molding part 200 facing away from the first molding part 100. It can be understood that, since the opposite end of the baffle can be obtained after the cutting structure 210 is cut, the baffle with the maximum size can be directly obtained after the first cutting structure 211 is cut by arranging the first cutting structure 211 at the edge of the second injection molding part 200 away from the first injection molding part 100. Set up like this, can satisfy the guide plate and to the prerequisite of the matched compactness of hand piece under, the material of minimize guide plate injection molding to reduce cost.

Referring to fig. 3, after the first cutting structure 211 is disposed at the edge of the substrate 240, the present embodiment further proposes that the first cutting structure 211 extends in an arc shape from the substrate 240 to a direction away from the first injection molding part 100. Because first cutting structure 211 is cut the back, can form the end of counterpointing of guide plate, and the end of counterpointing of guide plate can take place deformation when with counterpiece cooperation. Set up first cutting structure 211 into the arc, by the partial cutting back at first cutting structure 211, still can keep certain radian, like this, be favorable to the guide plate to join in marriage the end and take place deformation to be convenient for the guide plate with the assembly between the counterpart piece. And, curved guide plate joins in marriage the end, after the deformation with to the inseparable more of counterpiece laminating, be favorable to improving guide plate and to the inseparable nature of counterpiece cooperation. Of course, the design of the present application is not limited thereto, and in other embodiments of the present application, the first cutting structure 211 may also extend linearly, or extend in a wave shape, etc.

With reference to fig. 2, the first cutting structure 211 is gradually thickened from the end away from the substrate 240 to the substrate 240. Because first cutting structure 211 is formed at the edge that base plate 240 deviates from first portion 100 of moulding plastics, and first cutting structure 211 is cut the back, be used for with counterparty's cooperation to do not play the effect of water conservancy diversion, consequently set up first cutting structure 211 gradually thickly, can reduce first cutting structure 211's structural strength, so that first cutting structure 211 takes place deformation, thereby reduces guide plate and counterparty's complex degree of difficulty. Moreover, the gradually-thick arrangement of the first cutting structure 211 can save the materials of the guide plate injection molding part to a certain extent, thereby reducing the cost. In other embodiments of the present application, the first cutting structure 211 may also be configured to have a uniform thickness.

Referring to fig. 1 and fig. 2, in the present embodiment, the cutting structure 210 further includes a second cutting structure 212, and the second cutting structure 212 is disposed on a side of the first cutting structure 211 close to the first injection molding part 100 and extends in an arc shape. The second cutting structure 212 is located inside the first cutting structure 211 with reference to the first injection part 100. It is clear that by cutting the second cutting structure 212 a baffle of relatively small size can be obtained. The second cutting structure 212 is arranged to be arc-shaped, which aims to improve the convenience of the matching of the guide plate and the counterpart piece and improve the tightness of the matching of the guide plate and the counterpart piece. Meanwhile, in the baffle in which the second cutting structure 212 is not cut, since the second cutting structure 212 is configured in an arc shape, the surface shape thereof is also beneficial to the passage of fluid, so as to improve the flow guiding function of the baffle. 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, and the like.

Preferably, the arc of the second cutting structure 212 is larger than the arc of the first cutting structure 211. As can be seen from the above, the second cutting structure 212 is disposed inside the first cutting structure 211, so that, unlike the first cutting structure 211, the second cutting structure 212 also has a function of supporting the baffle before being cut. Therefore, setting the radian of the second cutting structure 212 to be greater than the first cutting structure 211 can increase the structural strength of the second cutting structure 212 to improve the structural strength of the baffle. And, set up to gradually thickly different from the direction of keeping away from the end side of the second portion of moulding plastics 200 to the second portion of moulding plastics 200 with the thickness of first cutting structure 211, for the structural strength who guarantees the guide plate, the thickness of second cutting structure 212 evenly sets up. Of course, in some embodiments of the present disclosure, the curvature of the second cutting structure 212 may be equal to or less than the curvature of the first cutting structure 211, and the thickness may also vary, provided the structural strength of the baffle is sufficient.

Referring to fig. 1 and fig. 2, the substrate 240 includes a first connecting plate 220 and a second connecting plate 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 molding part 100, and the second connecting plate 230 and the first connecting plate 220 are stacked. Since the first cutting structure 211 and the second cutting structure 212 are both arc-shaped, and the first connecting plate 220 and the second connecting plate 230 are stacked, it can be understood that the arc center directions of the first cutting structure 211 and the second cutting structure 212 are located on the same side of the second injection molding part 200. Like this, can simplify the structural design of guide plate injection molding, can strengthen the deformability of guide plate moreover, make the guide plate not fragile. Meanwhile, the first connecting plate 220 and the second connecting plate 230 are stacked and arranged, and have a certain avoiding effect, so that the guide plate can be conveniently installed in a product. Of course, in other embodiments of the present application, when the first cutting structure 211 and the second cutting structure 212 are both configured to be arc-shaped, the arc centers of the first cutting structure 211 and the second cutting structure 212 may be located on both sides of the second injection molding part 200.

Referring to fig. 1 and fig. 2, the cutting structure 210 further includes a third cutting structure 213, and the third cutting structure 213 is disposed on a side of the second cutting structure 212 close to the first injection molding part 100 and protrudes from the substrate 240. With reference to the first injection molding part 100, the third cutting structure 213 is located inside the second cutting structure 212, and obviously, a baffle with a smaller size can be obtained by cutting the third cutting structure 213. Specifically, in the present embodiment, the third cutting structure 213 is protruded on the second connection plate 230. Set up third cutting structure 213 to protruding and locate on base plate 240, compare in the flat face, can strengthen the structural strength of second portion 200 of moulding plastics, and then strengthen the structural strength of guide plate. And, the third cutting structure 213 can also form a distinct cutting mark on the second injection molding part 200 to facilitate the user operation.

Preferably, the second connecting plate 230 is recessed corresponding to the third cutting structure 213. Thus, the thickness of the baffle at the third cutting structure 213 can be more even, which is beneficial to the injection molding of the second injection molding part 200.

Referring to fig. 2 and 3, the third cutting structure 213 includes a first inclined section 213a, a second inclined section 213b and a connecting section 213 c. Wherein the connection segment 213c is connected between the first inclined segment 213a and the second inclined segment 213b, and is disposed parallel to the second connection plate 230; the first inclined segment 213a extends obliquely from the second cutting structure 212 in the direction of the connecting plate 213c, and the second inclined segment 213b extends obliquely from the connecting segment 213c in the direction of the first injection part 100. Providing the third cutting structure 213 as a three-stage structure can simplify the structural design of the third cutting structure 213, so as to facilitate the formation of the third cutting structure 213. It should be noted that, in this embodiment, since the injection-molded part of the air deflector is an injection-molded part of an automobile air deflector, the third cutting structure 213 may be used to be cut and cooperate with other parts on the automobile to position or fix the air deflector.

It should be noted that the design of the present application is not limited to providing three cutting structures 210 on the second injection molding part 200, and one, two, four, five or even more cutting structures 210 may be provided on the second injection molding part 200 according to different actual requirements.
