[0005] (2) Normal corrugated dust covers are extremely easy to be damaged when they are taken out after the mold is opened, which increases production costs.

[0028] The present application will be further described below with reference to specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0029] In the description of this application, it should be noted that the directional terms such as "center", "lateral", "longitudinal", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", and "counterclockwise" indicate the orientation and positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. They should not be construed as limiting the specific protection scope of this application.

[0030] It should be noted that the terms "first," "second," etc., in the specification and claims of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0031] The terms “comprising” and “having”, and any variations thereof, in the specification and claims of this application are intended to cover non-exclusive inclusion, for example, a process, method, system, product, or device that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or device.

[0032] One preferred embodiment of this application, such as Figures 1 to 8 As shown, a corrugated dust cover molding die includes a pair of molding molds 1 and demolding parts 2 slidably disposed on the two molding molds 1 respectively. The demolding parts 2 on the two molding molds 1 are arranged opposite to each other. The demolding parts 2 can cooperate with the molding molds 1 to form a cavity 10 for molding the corrugated dust cover when the molding molds 1 are closed, and the demolding parts 2 can disengage the molded corrugated dust cover from the cavity 10 when the molding molds 1 are opened.

[0033] It should be noted that, in existing corrugated dust cover molding molds, the process of removing the already formed corrugated dust cover from the cavity 10 after mold opening is extremely cumbersome, which significantly impacts production efficiency. Furthermore, in traditional processes, the formed dust cover is very easily damaged during removal, further increasing production costs.

[0034] Therefore, in this embodiment, a demolding component 2 is provided on the molding mold 1. The demolding component 2 can automatically demold the corrugated dust cover after the two molding molds 1 are opened, simplifying the cumbersome demolding process of the corrugated dust cover in the traditional process. In addition, the demolding component 2 is not easily damaged during the demolding process of the corrugated dust cover. This design not only improves the production efficiency of the corrugated dust cover, but also reduces the production cost to a certain extent.

[0035] In this embodiment, the demolding components 2 are slidably mounted on the two molding molds 1 respectively, and the demolding components 2 on the two molding molds 1 are arranged opposite to each other. At the same time, the demolding components 2 can cooperate with the two molding molds 1 when the two molding molds 1 are closed to form a cavity 10 for molding the corrugated dust cover.

[0036] It should be understood that since the demolding component 2 can cooperate with the two molding molds 1 when the two molding molds 1 are closed to form the cavity 10 for molding the corrugated dust cover, the structure of the two molding molds 1 must be the same.

[0037] Understandably, the demolding component 2 allows the formed corrugated dust cover to detach from the cavity 10. As is well known, the corrugated dust cover has a certain height, and the thickness of the demolding component 2 can be set to be either thick or thin. However, if the thickness of the demolding component 2 is set too thick, although it can detach the corrugated dust cover from the cavity 10, a subsequent problem arises: an excessively thick demolding component 2 becomes difficult to separate from the formed corrugated dust cover, requiring further time to separate them, which is counterproductive and similar to the problems encountered in traditional processes. Simultaneously, if the thickness of the demolding component 2 is too thin, it will inevitably generate some impact force during demolding; however, an excessively thin demolding component 2 impacting the corrugated dust cover may damage it.

[0038] Therefore, in this embodiment, as Figure 2 As shown, multiple demolding components 2 are selected, their thickness is limited, and they are distributed along the axial direction of the cavity 19. For example, three demolding components 2 with limited thickness are arranged along the axial direction of the cavity 10 on a single molding mold 1, respectively located in the upper, middle, and lower parts of the molding mold 1. Multiple demolding components 2 with limited thickness can cooperate to stably demold the formed corrugated dust cover, and because the thickness of the demolding components 2 is limited, demolding is easier than demolding the entire cavity 10. The number and distribution of the demolding components 2 described above are merely illustrative examples, and can be set according to the actual needs of those skilled in the art.

[0039] In this embodiment, as can be seen from the above, the demolding component 2 can cooperate with the two molding molds 1 when the two molding molds 1 are closed to form a complete cavity 10 for molding the corrugated dust cover.

[0040] It is understandable that the edge of the corrugated dust cover is arc-shaped, that is, the cavity 10 is arc-shaped. The demolding component 2 can cooperate with the two molding molds 1 when they are closed to form the cavity 10, so the end face of the demolding component 2 that cooperates with the molding mold 1 to form the cavity 10 is arc-shaped. Therefore, in this embodiment, the demolding component 2 has a molding groove 24 on the end face that cooperates with the molding mold 1 to form the cavity 10. The molding groove 24 is arc-shaped so that after the two molding molds 1 are opened, when the two opposing demolding components 2 demold the corrugated dust cover, the corrugated dust cover remains relatively stationary at the positions of the two molding grooves 24. This is equivalent to the opposing demolding components 2 on the two molding molds 1 remaining abutted within a set distance of the mold opening, so that the formed corrugated dust cover separates from the cavity 10 by maintaining its position.

[0041] Therefore, in this embodiment, the number of demolding parts 2 on the individual molding mold 1 is limited to multiple, and they are distributed along the axial direction of the cavity 10. The height of the molding groove 24 along the axial direction of the cavity 10 is 5% to 10% of the height of the corrugated dust cover. At the same time, the height of the molding groove 24 along the axial direction of the cavity 10 corresponds to at least one full waveform height of the corrugated dust cover.

[0042] It is also understandable that the arc length of the forming groove 24 is particularly important in this embodiment. If the arc length of the forming groove 24 is too short, after the two forming molds 1 open, the demolding component 2 may not be able to stably demold the formed corrugated dust cover, and the corrugated dust cover may fall off during the demolding process. Therefore, in this embodiment, the arc length of the forming groove 24 is limited to 5% to 50% of the circumference of the corrugated dust cover.

[0043] It should be noted that the overall structure of the corrugated dust cover is relatively fragile and easily damaged during demolding. If the edge of the demolding component 2 comes into contact with the crest of the corrugated dust cover during demolding, the corrugated dust cover is very likely to be damaged during the demolding process.

[0044] Therefore, in this embodiment, the position of the parting line 23 of the demolding component 2 is extremely important. As mentioned above, if the parting line 23 of the demolding component 2 is positioned against the crest of the corrugated dust cover, the corrugated dust cover may be damaged during demolding. Similarly, if the parting line 23 of the demolding component 2 is positioned between the crest and trough of the corrugated dust cover, it is also easy to damage the corrugated dust cover when the demolding component 2 demolds it. Therefore, in this embodiment, the edge of the molding groove 24 is defined to correspond to the trough of the corrugated dust cover, so that the parting line 23 of the demolding component 2 corresponds to the trough of the corrugated dust cover.

[0045] It is understandable that if the parting line 23 of the demolding part 2 is aligned with the trough of the corrugated dust cover, the corrugated dust cover can minimize the impact force generated by the demolding part 2 during demolding, thus ensuring the integrity of its structure.

[0046] In this embodiment, all the above functions depend on the demolding component 2 being slidably installed on the molding mold 1. There are various ways to specifically install the demolding component 2 on the molding mold 1, including but not limited to the two described below.

[0047] Method 1: The demolding component 2 is slidably installed on the molding mold 1, and the demolding component 2 is driven by a screw and a motor.

[0048] Method 2: For example Figure 3 As shown, the demolding component 2 is elastically mounted on the molding mold 1 via the elastic component 22.

[0049] It should be understood that both of the above-mentioned configuration methods can meet the requirements of this application, and those skilled in the art can choose according to actual needs; in this embodiment, the second method is preferred.

[0050] Specifically, the molding mold 1 is provided with an installation cavity 11, and the demolding component 2 is elastically installed in the installation cavity 11 through the elastic element 22. At the same time, the demolding component 2 is provided with a connecting cavity 20 at one end relative to the molding groove 24, and a guide rod 21 is provided in the connecting cavity 20. The connecting cavity 20 and the elastic element 22 are connected so that the demolding component 2 can be elastically installed in the molding mold 1.

[0051] The basic principles, main features, and advantages of this application have been described above. Those skilled in the art should understand that this application is not limited to the above embodiments. The embodiments and descriptions in the specification are merely the principles of this application. Various changes and modifications can be made to this application without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection claimed by this application is defined by the appended claims and their equivalents.
