[0002] A flushing charging port cover typically consists of a cover body and a guide arm. It is usually produced by injection molding. During the injection molding and demolding process, the connection between the cover body and the guide arm is relatively fragile. If the force applied when picking up the flushing charging port cover during demolding is uneven, it can easily cause the guide arm to twist, leading to an increase in the scrap rate.
[0003] Therefore, how to avoid the guide arm of the flushing charging port cover being twisted during demolding due to the injection mold used in the production of flushing charging port covers is a technical problem that urgently needs to be solved by those skilled in the art.
[0004] It should be noted that the information disclosed in this background section is only for understanding the background technology of the present application concept, and therefore, the above description is not considered to constitute prior art information. Utility Model Content

[0013] In one optional embodiment, the bottom surface of the mounting groove is symmetrically provided with a plurality of positioning elements, and the lower end surface of the intermediate mold is provided with a number of positioning holes corresponding to the number of positioning elements.
[0014] In one alternative embodiment, the positioning element is connected to a vertical lifting mechanism located inside the lower mold.
[0015] In one alternative embodiment, the lifting mechanism includes a lifting cylinder and a support rod, the support rod passing through the bottom surface of the mounting groove and connecting to the lower end surface of the positioning member.
[0016] Secondly, embodiments of this disclosure also provide an injection mold, comprising:
[0017] The upper mold has at least one slot on its lower end face;
[0018] The middle mold has grooves on its side and a core mold on its upper surface;
[0019] The lower mold has a mounting groove on its upper end face suitable for placing the middle mold;
[0020] When the upper mold, middle mold, and lower mold are closed, the slot, groove, and core mold form an injection cavity; and,
[0021] A sliding mechanism is provided between the side wall of the intermediate mold and the inner wall of the mounting groove;
[0022] During demolding, the middle mold moves upward via a sliding mechanism.
[0023] In one optional embodiment, the sliding mechanism includes a sliding member disposed on the side wall of the intermediate mold and a sliding groove disposed on the inner wall of the mounting groove.
[0024] During demolding, the middle mold moves upward along the slide groove via a sliding member.

[0027] In one alternative embodiment, the lifting mechanism includes a lifting cylinder and a support rod, the support rod passing through the bottom surface of the mounting groove and connecting to the lower end surface of the positioning member.
[0028] The beneficial effect of this utility model is that the injection mold for producing the flush charging port cover forms an injection cavity through the cooperation of the upper mold, the middle mold and the lower mold. After the flush charging port cover is injection molded, the middle mold is adapted to move upward along the sliding groove on the inner wall of the mounting groove through the sliding part of its side wall to achieve demolding.

[0043] Research has revealed the following drawbacks of the existing technology: during the demolding process of the flushing charging port cover injection molding, the connection between the cover and the guide arm is relatively fragile. If the force applied when removing the flushing charging port cover during demolding is uneven, it can easily cause the guide arm to twist, leading to an increase in the scrap rate.
[0044] Based on the above research, this disclosure provides an injection mold for producing a flush charging port cover, which achieves demolding by moving the middle mold upward, thereby avoiding the guide arm from being twisted by lateral force and solving the above problems.
[0045] The shortcomings of the above solutions are the result of the inventor's practical experience and careful research. Therefore, the discovery process of the above problems and the solutions proposed in this disclosure should be considered as the inventor's contribution to this disclosure.
[0046] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.
[0047] The following detailed description, with reference to the accompanying drawings, describes some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.
[0048] See Figure 1 and Figure 3This disclosure provides an injection mold for producing a washable charging port cover, comprising: an upper mold 100, the lower end face of which is provided with at least one slot 110 adapted to the shape of the cover body 400; a middle mold 200, the side of which is provided with a groove 210 adapted to the shape of the guide arm 500, and the upper end face of the middle mold 200 is also provided with a core mold 220; and a lower mold 300, the upper end face of which is provided with an installation groove 310 suitable for placing the middle mold 200; wherein, when the upper mold 100, the middle mold 200 and the lower mold 300 are closed, the slot 110, the groove 210 and the core mold 220 form an injection cavity for the washable charging port cover.
[0049] See also Figure 1 The middle mold 200 has a sliding member 240 on its side wall, and the inner wall of the mounting groove 310 has a sliding groove 312 that mates with the sliding member 240. When the charging port cover is injection molded and demolded, the middle mold 200 moves upward along the sliding groove 312 to achieve demolding. By adopting an upward demolding method, the connection between the cover 400 and the guide arm 500 is not subjected to lateral forces, thus avoiding the guide arm 500 being subjected to lateral forces during demolding and preventing the guide arm 500 from twisting.
[0050] See also Figure 1 In some embodiments, the bottom surface of the mounting groove 310 is symmetrically provided with a plurality of positioning elements 311, and the lower end surface of the middle mold 200 is provided with a number of positioning holes 230 corresponding to the number of positioning elements 311. Through the cooperation of the positioning elements 311 and the positioning holes 230, the assembly error between the middle mold 200 and the lower mold 300 can be eliminated, ensuring that the cavity alignment between the groove 210 of the middle mold 200 and the slot 110 of the upper mold 100 and the core mold 220 is accurate, so that the guide arm 500 has no residual internal stress after injection molding, thereby reducing the uneven force on the guide arm 500 caused by cavity misalignment during demolding from the root.
[0051] See Figure 2 In some embodiments, the positioning element 311 is connected to a vertical lifting mechanism 320 located inside the lower mold 300. During demolding, the middle mold 200 rises vertically by lifting the symmetrically arranged positioning elements 311 through the lifting mechanism 320. Preferably, the symmetrically arranged positioning elements 311 ensure that the middle mold 200 is subjected to uniform force at all points during demolding, avoiding tilting or jamming of the middle mold 200 due to unilateral force, further eliminating lateral force during demolding, and protecting the structural integrity of the guide arm 500.
[0052] See also Figure 2In some embodiments, the lifting mechanism 320 includes a lifting cylinder 321 and a support rod 322. The support rod 322 passes through the bottom surface of the mounting groove 310 and connects to the lower end surface of the positioning member 311. Each positioning member 311 is connected to the same lifting cylinder 321 via an independent support rod 322, so that the stroke height of the support rod 322 is synchronized, preventing the middle mold 200 from tilting or jamming due to uneven local force, thereby ensuring that the guide arm 500 is subjected to uniform force during demolding.
[0053] See Figure 1 Some embodiments also provide an injection mold, including: an upper mold 100, the lower end face of which is provided with at least one slot 110; a middle mold 200, the side of which is provided with a groove 210, and the upper end face of the middle mold 200 is provided with a core mold 220; and a lower mold 300, the upper end face of which is provided with a mounting groove 310 suitable for placing the middle mold 200; wherein, when the upper mold 100, the middle mold 200 and the lower mold 300 are closed, the slot 110, the groove 210 and the core mold 220 form an injection cavity. A sliding mechanism is provided between the side wall of the middle mold 200 and the inner wall of the mounting groove 310; during demolding, the middle mold 200 moves upward through the sliding mechanism.
[0054] See also Figure 1 In some embodiments, the sliding mechanism includes a slider 240 disposed on the side wall of the intermediate mold 200 and a groove 312 disposed on the inner wall of the mounting groove 310. During demolding, the intermediate mold 200 moves upward along the groove 312 via the slider 240.
[0055] In summary, the injection mold for producing the flush charging port cover forms an injection cavity through the cooperation of the upper mold 100, the middle mold 200, and the lower mold 300. After the flush charging port cover is injection molded, the middle mold 200 is adapted to move upward along the sliding groove on the inner wall of the mounting groove 310 via the sliding member 240 on its side wall to achieve demolding. The upward movement ensures that the connection between the cover body 400 and the guide arm 500 is not subjected to lateral force, thereby avoiding the guide arm 500 being subjected to lateral force during demolding and causing the guide arm 500 to twist.
[0056] In the description of the embodiments of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0057] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing this utility model 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, and therefore should not be construed as a limitation of this utility model. Furthermore, terms such as "first," "second," and other numerical terms used herein do not imply order or sequence unless expressly indicated herein. Therefore, without departing from the teachings of the exemplary embodiments, the first element, component, region, layer, or segment discussed above may be referred to as the second element, component, region, layer, or segment.
[0058] Spatially relative terms, such as “inside,” “outside,” “below,” “below,” “down,” “above,” “up,” etc., may be used herein to describe the relationship between one element or feature illustrated in the figures and another element or feature. In addition to the orientations depicted in the figures, spatially relative terms may be intended to cover different orientations of the device in use or operation. For example, if the device in the figure is flipped, an element described as “below” or “below” other elements or features would be oriented as “above” other elements or features. Thus, the example term “below” can cover both above and below orientations. The device may be oriented in other ways (rotated 90 degrees or in other orientations), and the spatially relative descriptors used herein are interpreted accordingly.
[0059] In the above discussion, unless otherwise stated, when used to describe numerical values, the terms “about,” “approximately,” “basically,” etc., indicate a change of + / - 10% in that value.
[0060] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
