[0002] A charging port cover typically includes a base assembly, a hinge assembly, an outer panel, and an actuator. The outer panel matches the outer panel of the vehicle's side panel and has high surface difference (DTS) requirements. The outer panel is mounted on the hinge assembly, and the actuator controls the height of the hinge assembly through a latch, thereby adjusting the surface difference between the charging port cover's outer panel and the side panel.

[0003] The actuator is mounted on the base assembly via two boss columns. The position and height of the actuator can be adjusted by adjusting the height of the boss columns, thereby adjusting the surface difference of the outer panel of the charging port cover.

[0004] In the past, only one insert was made for the boss column in the charging port cover base component mold. The insert was detachably connected to the mold. However, the insert needed to be replaced every time the height of the boss column needed to be adjusted, resulting in a long mold repair cycle and low production efficiency. Utility Model Content

[0027] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0028] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" 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.

[0029] In related technologies, the actuator is mounted on the base assembly via two boss columns. Adjusting the height of the boss columns allows for adjustment of the actuator's position and height, thereby adjusting the surface difference of the charging port cover's outer panel. In previous charging port cover base assembly molds, only one insert was made for the boss column, which was detachably connected to the mold. However, this insert needed to be replaced each time the boss column height needed adjustment, resulting in long mold repair cycles and low production efficiency.

[0030] In view of this, such as Figures 1-7 As shown, some embodiments of this utility model provide a charging port cover mold, including a mold body 1, a pin 2, a gasket 10, and a fixing block 3; the pin 2 is inserted into the mold body 1 and slidably connected to the mold body 1; the mold body 1 has a mold cavity for forming an injection molded part 4; one end of the pin 2 extends into the mold cavity to form a boss 5 on the injection molded part 4; the other end of the pin 2 is connected to the fixing block 3; the gasket 10 is disposed between the fixing block 3 and the mold body 1; both the fixing block 3 and the gasket 10 are detachably connected to the mold body 1 by bolts; the gasket 10 is used to adjust the distance between the fixing block 3 and the surface of the mold body 1; the fixing block 3 can drive the pin 2 to slide relative to the mold body 1 to adjust the height of the formed boss 5.

[0031] In the above embodiment, the mold body 1, insert pin 2, gasket 10, and fixing block 3 can all be made of metal. The end of insert pin 2 that extends into the mold cavity can be set as conical or cylindrical. The diameter of insert pin 2 used to form boss pillar 5 is smaller than the diameter of the contact point between insert pin 2 and mold body 1. Under the action of fixing block 3 and gasket 10, insert pin 2 can move relative to mold body 1 along the axial direction, thereby adjusting the length of insert pin 2 entering the mold cavity and thus adjusting the height of boss pillar 5 formed on injection molded part 4. Fixing block 3 is used to fix insert pin 2 and can also move relative to mold body 1 with insert pin 2. The mold cavity is used to form injection molded part 4 after being filled with molten plastic, and boss pillar 5 is formed on injection molded part 4 with the cooperation of insert pin 2. The movement of insert pin 2, gasket 10, and fixing block 3 relative to mold body 1 can all be fixed, so that the distance of adjustment of insert pin 2 under the cooperation of fixing block 3 and gasket 10 can be fixed to meet the production requirements.

[0032] The thickness of the shim 10 can be changed. The shim 10 can be an inflatable shim 10, thereby adjusting the distance between the fixing block 3 and the surface of the mold body 1. Alternatively, the shim 10 can be replaced by detachably connecting shims of different thicknesses, thereby adjusting the distance between the fixing block 3 and the surface of the mold body 1, and thus adjusting the height of the formed boss column 5.

[0033] This utility model provides a charging port cover mold, including a mold body 1, a pin 2, a gasket 10, and a fixing block 3. The pin 2 is inserted into the mold body 1 and slidably connected to the mold body 1. The mold body 1 has a cavity for forming an injection molded part 4. One end of the pin 2 extends into the cavity to form a boss 5 on the injection molded part 4. The other end of the pin 2 is connected to the fixing block 3. The gasket 10 is disposed between the fixing block 3 and the mold body 1. Both the fixing block 3 and the gasket 10 are detachably connected to the mold body 1 by bolts. The gasket 10 is used to adjust the distance between the fixing block 3 and the surface of the mold body 1. By setting gaskets 10 of different thicknesses, the fixing block 3 can drive the pin 2 to slide relative to the mold body 1 to adjust the depth of one end of the pin 2 extending into the cavity, thereby controlling the height of the formed boss 5. The adjustment is simpler and more precise, solving the technical problems of long mold repair cycle and low production efficiency in the prior art, and achieving the technical effect of short mold repair cycle and high production efficiency.

[0034] In an optional embodiment, a plurality of gaskets 10 are provided, and the plurality of gaskets 10 are detachably connected to the fixing block 3 by bolts, and at least one gasket 10 is selectively provided between the surface of the fixing block 3 and the mold body 1.

[0035] In the above embodiments, multiple shims 10 can be provided. The multiple shims 10 have the same projected size, but their thicknesses can be set differently. The multiple shims 10 can be stacked together for use. Thus, shims 10 of the desired thickness can be selectively set between the fixing block 3 and the mold body 1. When the desired thickness between the fixing block 3 and the mold is large, the requirements of the fixing block 3 can be achieved by stacking multiple shims 10, thereby satisfying a wider range of height adjustment for the formed boss column 5.

[0036] In an optional embodiment, the gasket 10 is provided with a through hole for the bolt to pass through, and the gasket 10 is also provided with a relief groove, which is spaced apart from the through hole. The relief groove extends along the width direction of the gasket 10, and the insert pin 2 extends into the relief groove through the opening of the relief groove.

[0037] In the above embodiment, the through hole can be circular, and there can be two through holes. The two through holes are respectively set on both sides of the relief groove. Correspondingly, there can also be two bolts. The two bolts pass through the through holes on the fixing block 3 and the gasket 10 in sequence and are threadedly connected to the mold body 1, thereby fixing the gasket 10 and the fixing block 3. During the installation of the gasket 10, the relief groove on the gasket 10 can be first locked on the insert pin 2, and then the gasket 10 can be moved towards the fixing block 3 so that the gasket 10 is attached to the fixing block 3. At this time, the two bolts on the fixing block 3 protrude through the two through holes on the gasket 10. Then, the fixing block 3 and the gasket 10 are pressed against the surface of the mold body 1 and fixed by bolts.

[0038] Optionally, the shim 10 can also be set as a ring shape, with each bolt fitted with an individual shim 10. When installing the shim 10, the shim 10 can be fitted onto the bolt passing through the fixing block 3, and then the shim 10 can be moved along the direction close to the fixing block 3 until the shim 10 abuts against the fixing block 3. It should be noted that the total thickness of the shims 10 fitted on different bolts is set to be the same, so that the distance between the fixing block 3 and the surface of the mold body 1 can be adjusted by using the individual ring-shaped shim 10.

[0039] In an optional embodiment, the side wall of the fixing block 3 is provided with a snap-fit ​​groove 6, and one end of the insert pin 2 is provided with a snap-fit ​​flange 7. The snap-fit ​​flange 7 is snapped into the snap-fit ​​groove 6 to fix the insert pin 2 and the fixing block 3.

[0040] In the above embodiment, the snap-fit ​​groove 6 can penetrate through the fixing block 3, or at least penetrate through half the width of the fixing block 3, thereby satisfying the requirement that the snap-fit ​​flange 7 is completely submerged in the snap-fit ​​groove 6. The cross-section of the snap-fit ​​groove 6 is T-shaped, and the diameter of the snap-fit ​​flange 7 on the end face of the insert pin 2 is larger than the diameter of the insert pin 2. Thus, after the snap-fit ​​flange 7 extends into the snap-fit ​​groove 6, the insert pin 2 can extend out through the snap-fit ​​groove 6. Therefore, when the fixing block 3 moves in the axial direction of the insert pin 2, the insert pin 2 can be moved through the snap-fit ​​groove 6 and the snap-fit ​​flange 7, thereby achieving the effect of adjusting the length of the insert pin 2 extending into the mold cavity.

[0041] In an optional embodiment, the fixing block 3 is provided with two countersunk holes, which are respectively located on both sides of the axis of the insert pin 2. Both countersunk holes are provided through the fixing block 3 along the height direction, and each countersunk hole is connected to the mold body 1 by a bolt.

[0042] In an optional implementation, the axes of the two countersunk holes are symmetrically arranged relative to the axis of the insert 2.

[0043] In the above embodiment, both countersunk holes can be circular and penetrate the fixing block 3 along the height direction of the fixing block 3. Two threaded holes can be provided on the surface of the mold body 1. The two threaded holes are respectively arranged to coincide with the axis of the two countersunk holes, so that the bolt in each countersunk hole can be connected to the threaded hole of the mold body 1. While connecting the fixing block 3 to the mold body 1 with bolts, the space occupied by the bolts can also be reduced by the countersunk holes. The axes of the two symmetrically arranged countersunk holes are parallel to each other and parallel to the axis of the insert pin 2, so that the two bolts can be more firmly connected to the mold body 1, and the connection between the fixing block 3 and the gasket 10 is more secure.

[0044] In an optional embodiment, the surface of the mold body 1 is provided with an installation groove 9, the fixing block 3 and the gasket 10 are embedded in the installation groove 9, and the insert pin 2 is inserted through the bottom of the installation groove 9, so that the end of the fixing block 3 away from the injection molded part 4 is lower than the surface of the mold body 1.

[0045] In the above embodiment, the cross-section of the mounting groove 9 can be similar to that of the fixing block 3. The size of the mounting groove 9 is slightly larger than that of the fixing block 3, so that the fixing block 3 can smoothly enter the mounting groove 9. The depth of the mounting groove 9 is greater than the height of the fixing block 3 and the gasket 10 combined. So that after the gasket 10 and the fixing block 3 are fixed in the mounting groove 9, the fixing block 3 cannot protrude from the mounting groove 9, reducing the space occupied by the fixing block 3 and making the appearance neater.

[0046] In an optional embodiment, a fixing hole 8 is provided in the mold body 1. One end of the fixing hole 8 is located at the bottom of the mounting groove 9, and the other end of the fixing hole 8 is connected to the mold cavity. The insert pin 2 is inserted into the fixing hole 8 and slidably connected to the fixing hole 8.

[0047] In the above embodiment, the fixing hole 8 can be cylindrical. One end of the fixing hole 8 can be connected to the mold cavity, and the other end is set at the bottom of the mounting groove 9. The inner diameter of the fixing hole 8 can be the same as the outer diameter of the insert pin 2, or slightly larger than the diameter of the insert pin 2, so that the insert pin 2 can be tightly connected to the fixing hole 8 after it is inserted into the fixing hole 8. At the same time, the insert pin 2 can slide relative to the fixing hole 8, thereby limiting the movement direction of the insert pin 2 and making the formed boss column 5 more accurate.

[0048] In an optional embodiment, the axis of the pin 2 is set perpendicular to the surface of the fixing block 3.

[0049] In the above embodiment, the axis of the insert pin 2 is set perpendicular to the surface of the fixing block 3, so that the fixing block 3 can better fix the insert pin 2 and make the insert pin 2 more stable. At the same time, when the fixing block 3 drives the insert pin 2 to move, the adjusted position of the fixing block 3 is parallel to the original position, making it easier to adjust the depth of the insert pin 2 into the mold cavity through the shim 10.

[0050] In an optional embodiment, the axis of the bolt is arranged parallel to the axis of the insert 2.

[0051] In the above embodiment, since the axes of the two countersunk holes are symmetrically arranged relative to the insert pin 2, after the two bolts are inserted into the two countersunk holes respectively, the axes of the two bolts are also symmetrically arranged, and the axes of the bolts are parallel to the axis of the insert pin 2. At this time, the bolts can better fix the insert pin 2 through the fixing block 3, and no matter how many washers 10 are added, the bolts can be connected to the threaded holes after being inserted through multiple washers 10. The round holes on the washers 10 can be set in the same position.

[0052] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
