The invention provides a guide plate injection molding piece which is used for being cut to obtain guide plates with different specifications.
In the embodiment of the invention, as shown in fig. 1, the baffle injection molding member includes a first injection molding portion 100 and a second injection molding portion 200 formed on the first injection molding portion 100. The first injection molding portion 100 corresponds to a mounting structure of the molded deflector, and the second injection molding portion 200 includes a substrate 240 and a plurality of cutting structures 210. The plurality of dicing structures 210 are sequentially disposed on the substrate 240 at intervals, and the dicing structures 210 are raised or recessed and protruding on the substrate 240. The cutting structure 210 is used for cutting to form a mating end of the deflector, which is matched with the hand piece.
It will be appreciated that the baffle acts to direct the direction of movement of the fluid (gaseous or liquid) to enhance the operation of the product. Taking an example, the air conditioner baffle is generally disposed at an air outlet of the air conditioner to guide an air flow direction at the air outlet of the air conditioner, so as to improve user experience. And taking an upper guide plate of the automobile as an example, the upper guide plate can be matched with a front bumper of the automobile to play a role in sealing and guiding in the running process of the automobile, so that noise and wind resistance in the running process of the automobile are reduced. It can be seen that the baffle is not a separate component in the product and is required to be used with the product. Then, the first injection part 100 corresponds to the mounting structure of the baffle, and then can be regarded as the final cut target baffle, which corresponds to the structure of the fixed/movable fit of the product. Since the mounting structure of different guide plates may be changed according to the actual application, such as a stud, a screw, a threaded hole, etc., the specific structure of the first injection molding part 100 is not limited in this application. Specifically, the guide plate can be movably installed on the product or can be immovably installed on the product. In this embodiment, the structure or the parts of the product for matching with the deflector may be referred to as an opponent.
In this application, different deflectors are obtained by cutting the deflector injection-molded part in different cutting modes, so that a common structure exists between different deflectors. The second injection molding part 200 is used for cutting, so that the specification and the detail of the guide plate are different, and different guide plates are obtained. Since these baffles are ultimately cut, there must be dimensional variation between different baffles. And the size of the baffle injection molding necessarily meets the maximum size of each baffle. The plurality of cutting structures 210 are sequentially arranged on the substrate 240 at intervals, so that the change from the maximum size to the minimum size of the baffle can be adapted to obtain baffles with different sizes. The cutting structure 210 may also be used as a cutting mark on the second injection molding portion 200, so as to facilitate the operator to cut the injection molding of the baffle. Since the cutting structure 210 is raised or recessed and protrudes from the substrate 240, and when cutting, the cutting structure 210 is cut to form the mating end of the baffle and the counterpart, so that the extending direction of the mating end of the baffle is also staggered with the extending direction of the substrate 240, and thus, when the baffle is mated with the counterpart, the mating end of the baffle is easy to deform and is easy to be in interference fit with the counterpart.
Because the existing mould can only be used for injection molding a certain specific guide plate, the guide plate can only be matched with a certain specific product for use, and cannot be matched with other products. Even though the structures of the deflectors of the plurality of products are generally similar, the deflectors cannot be replaced among different deflectors. That is, the existing guide plates have poor universality, so that different dies are required for manufacturing different guide plates, and the production cost is high. The utility model provides a guide plate injection molding sets up a plurality of cutting structures 210 through in the second injection molding for the guide plate injection molding is cut the back, can obtain different guide plates, with the different product of adaptation, and the wild-type nature is strong. Therefore, in the process of producing a plurality of guide plates with similar structures, the design of a die is reduced, and the production cost is greatly reduced.
Furthermore, because of the nature of plastics, the baffles are often sheet-like structures, and therefore the baffles generally have varying degrees of deformability. By this deformability, an interference fit of the deflector with the opponent piece can theoretically be achieved. However, the mating ends of the prior deflector and the counter-piece are straight extensions. When the guide plate is in interference fit with the opponent, the paired ends of the guide plate are not easy to deform, and a worker is required to apply larger pressure so that the guide plate is deformed integrally, and the interference fit between the guide plate and the opponent can be realized. Therefore, the guide plate has certain difficulty in operation, and after the guide plate is integrally deformed, the guide effect and the strength of the guide plate are easily influenced to a certain extent, so that the guide plate is not beneficial to the work of products. Through the technical scheme of the application, because the cutting structure 210 bulges or is sunken and is convexly arranged on the substrate 240, the extending direction of the opposite ends of the guide plates is staggered with the extending direction of the substrate 240, so that when the guide plates are in interference fit with the opposite parts, the pressure applied to the guide plates by the opposite parts is staggered with the extending direction of the opposite ends of the guide plates, the opposite ends of the guide plates are easy to deform, and the whole guide plates are hardly deformed. Compared with the prior art, the guide plate injection molding part has the advantages that interference fit of the guide plate and the opponent is convenient to achieve, and the compactness of the guide plate and the opponent is improved. It should be noted that, in the present application, the substrate 240 is smoothly disposed, the surface thereof is a smooth arc surface or a straight surface, and the cutting structure 210 is raised or recessed with respect to the plane or the arc surface, and is protruding on the substrate 240.
Of course, the design of the present application is not limited thereto, and in some cases, the baffle may be a close fit or a clearance fit with the opponent. When the deflector is tightly matched with the opponent, the mating end which is staggered with the extending direction of the base plate 240 can improve the tightness of the fitting of the deflector and the opponent, thereby improving the matching tightness of the deflector and the opponent. When the guide plate is matched with the gap between the opponent pieces, the matched end of the guide plate can be used as a mark to improve the identification degree of the gap between the guide plate and the opponent pieces, so that the guide plate is convenient for the operation and the inspection of staff.
Specifically, in this embodiment, the baffle injection molding is an automobile baffle injection molding, and is injection molded by a single-cavity two-color molding process, the first injection molding portion 100 of the baffle injection molding is injection molded of a hard rubber material, and the second injection molding portion 200 is injection molded of a soft rubber material. Of course, the design of the present application is not limited thereto, and in other embodiments of the present application, the baffle may be an injection molding piece of another baffle, such as an air conditioner baffle injection molding piece. The material of the first injection molding portion 100 and/or the second injection molding portion 200 may be made of soft rubber and/or hard rubber, and the specific arrangement may be selected according to different actual use situations.
As shown in fig. 1 and fig. 2, the cutting structure 210 includes a first cutting structure 211, and the first cutting structure 211 is disposed at an edge of the second injection molding portion 200 facing away from the first injection molding portion 100. It will be appreciated that, since the mating end of the baffle can be obtained after the cutting structure 210 is cut, the first cutting structure 211 is disposed on the edge of the second injection molding portion 200 facing away from the first injection molding portion 100, and the baffle with the largest size can be directly obtained after the cutting of the first cutting structure 211. The setting like this can satisfy under the prerequisite of guide plate and opponent spare complex compactness, the material of guide plate injection molding is reduced as far as possible 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 in a direction away from the first injection molding portion 100. Since the first cutting structure 211 is cut, the mating end of the baffle is formed, and the mating end of the baffle is deformed when being matched with the opponent. The first cutting structure 211 is provided with an arc shape, and a certain radian can be maintained after the first cutting structure 211 is partially cut, so that the paired ends of the guide plates are favorably deformed, and the guide plates and the opponent pieces are conveniently assembled. And the arc-shaped guide plate pairing end is more tightly attached to the opponent piece after deformation, so that the matching tightness of the guide plate and the opponent piece is improved. 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 in a straight line, or in a wave shape, etc.
With continued reference to fig. 2, the first cutting structure 211 is gradually thickened from the end away from the substrate 240 toward the substrate 240. Because the first cutting structure 211 is formed at the edge of the substrate 240 away from the first injection molding part 100, and after the first cutting structure 211 is cut, the first cutting structure 211 is used for being matched with an opponent and does not play a role in guiding, the first cutting structure 211 is gradually thicker, so that the structural strength of the first cutting structure 211 can be reduced, the first cutting structure 211 is deformed conveniently, and the difficulty in matching the guide plate with the opponent is reduced. Moreover, the gradually-thick arrangement of the first cutting structure 211 can save the material 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 provided with a uniform thickness.
Referring to fig. 1 and 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 near the first injection molding portion 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 molding part 100. Obviously, a relatively small size of the baffle can be obtained by cutting the second cutting structure 212. The second cutting structure 212 is provided in an arc shape, which is the same as the first cutting structure 211 is provided in an arc shape, and is aimed at improving the convenience of the cooperation of the baffle and the opponent, and improving the tightness of the cooperation of the baffle and the opponent. Meanwhile, in the baffle plate in which the second cutting structure 212 is not cut, since the second cutting structure 212 is provided in an arc shape, the surface shape thereof is also advantageous for the fluid to pass through so as to improve the flow guiding function of the baffle 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 second cutting structure 212 has a curvature that is greater than the curvature 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, and the second cutting structure 212 has a function of supporting the baffle before being cut, unlike the first cutting structure 211. Therefore, the radian of the second cutting structure 212 is set to be greater than that of the first cutting structure 211, so that the structural strength of the second cutting structure 212 can be increased to improve the structural strength of the baffle. And, unlike the first cutting structure 211, which is provided to be gradually thicker from the end far from the second injection part 200 toward the second injection part 200, the thickness of the second cutting structure 212 is uniformly provided in order to secure structural strength of the baffle. Of course, in some embodiments of the present application, the arc of the second cutting structure 212 may be equal to or smaller than the arc of the first cutting structure 211, and the thickness thereof may also be changed, provided that the structural strength of the baffle is sufficient.
Referring to fig. 1 and fig. 2, the substrate 240 includes a first connection plate 220 and a second connection 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 portion 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 configured as arc shapes, and the first connecting plate 220 and the second connecting plate 230 are configured as lamination, it can be understood that the arc center directions of the first cutting structure 211 and the second cutting structure 212 are located at the same side of the second injection molding portion 200. Therefore, the structural design of the guide plate injection molding part can be simplified, and the deformability of the guide plate can be enhanced, so that the guide plate is not easy to damage. Meanwhile, the stacked arrangement of the first connecting plate 220 and the second connecting plate 230 also has a certain clearance function, so that the installation of the guide plate in the product is facilitated. Of course, in other embodiments of the present application, when the first cutting structure 211 and the second cutting structure 212 are both configured in an arc shape, the arc centers of the first cutting structure 211 and the second cutting structure 212 may be located at two sides of the second injection molding portion 200, respectively.
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 near the first injection molding portion 100 and protrudes out of the substrate 240. The third cutting structure 213 is located inside the second cutting structure 212 with reference to the first injection part 100, and it is apparent that a smaller-sized baffle can be obtained by cutting the third cutting structure 213. Specifically, in the present embodiment, the third cutting structure 213 is protruding on the second connection plate 230. The third cutting structure 213 is disposed protruding on the substrate 240, and compared with a flat plate surface, the structural strength of the second injection molding portion 200 can be enhanced, so that the structural strength of the baffle can be enhanced. And, the third cutting structure 213 can also form a distinct cutting mark on the second injection part 200 to facilitate the user's operation.
Preferably, the second connecting plate 230 is grooved corresponding to the third cutting structure 213. In this way, the thickness of the baffle at the third cutting structure 213 can be more even, which is beneficial for injection molding of the second injection molding portion 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 213c. Wherein 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 in the direction of the connecting plate 213c, and the second inclined section 213b extends obliquely from the connecting section 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 to facilitate formation of the third cutting structure 213. It should be noted that, in this embodiment, since the baffle injection molding is an automobile baffle injection molding, the third cutting structure 213 may be used to be matched with other parts of an automobile to position or fix the baffle in addition to being cut.
It should be noted that the design of the present application is not limited to only providing three cutting structures 210 on the second injection molding portion 200, and one, two, four, five or more cutting structures 210 may be provided on the second injection molding portion 200 according to different actual requirements.
Referring to fig. 2, in the present embodiment, the third cutting structure 213 is disposed on the second connecting plate 230 in a protruding manner, and the third cutting structure 213 is used as a boundary, so that for facilitating the installation of the automobile deflector, a concave avoidance surface is formed on a side of the second connecting plate 230 away from the third cutting structure 213, and the concave avoidance surface is located on a side of the third cutting structure 213 close to the first injection molding portion 100.
The invention further provides a guide plate injection mold which is used for preparing the guide plate injection molding piece. The specific structure of the guide plate injection molding part refers to the above embodiment, and since the guide plate injection molding part prepared by the guide plate injection molding mold adopts all the technical schemes of all the embodiments of the guide plate injection molding part, the guide plate injection molding part at least has all the beneficial effects brought by the technical schemes of the embodiments, and the description is omitted herein.
The foregoing description is only of the preferred embodiments of the present invention and is not intended to limit the scope of the invention, and all equivalent structural changes made by the description of the present invention and the accompanying drawings or direct/indirect application in other related technical fields are included in the scope of the invention.
