[0022] The embodiments of the present utility model will be further described below in conjunction with the accompanying drawings. Example
[0023] like Figure 1-Figure 4 As shown, a mold structure for forming a leak-proof trim strip for an electric vehicle comprises a mold body 1, a demoulding mechanism 2 is provided on the inner side of the mold body 1, a fixed mold core 3 is provided on the inner side of the mold body 1, a partition sealing strip 4 is provided on the inner middle part of the fixed mold core 3, a leak-proof trim strip body 7 is formed on the inner side of the fixed mold core 3, an inclined top glue feeding block 5 is movably provided inside the fixed mold core 3, and a side glue feeding port 6 is provided on the inner side of the fixed mold core 3.
[0024] The working principle of the above technical solution is as follows:
[0025] During use, the glue can be injected from the top and the side under the action of the oblique push-in glue block 5, so that the anti-leakage decorative strip body 7 can enter the inner side of the fixed mold core 3 for molding. After molding is completed, it can be demolded quickly under the action of the demolding mechanism 2, and can be demolded stably. It can also prevent the anti-leakage decorative strip body 7 from warping and deformation, and is easy to use.
[0026] In another embodiment, if Figure 3 As shown, the demoulding mechanism 2 includes a slider 8 , one side of the slider 8 is provided with a turning core 9 , and one side of the slider 8 is provided with a straight side core 10 .
[0027] When the slider 8 moves laterally, the ends of the steering core 9 and the straight side core 10 can be drawn out from the inside of the anti-leakage decorative strip body 7 after molding, thereby completing the demoulding process of the anti-leakage decorative strip body 7, which is easy to operate.
[0028] In another embodiment, if Figure 3 As shown, the separation sealing strip 4 separates and seals the interior of the molding core.
[0029] It is convenient to separate the interior of the fixed mold core 3 when injecting glue into the inner side of the fixed mold core 3, and form two chambers for production and processing, which can also prevent the glue from sticking.
[0030] In another embodiment, if Figure 3 As shown, a fixed limiting guide block 11 is symmetrically provided on the top of the fixed mold core 3 .
[0031] It is convenient to fix the limiting guide block 11 so as to limit and guide the turning and drawing core 9 .
[0032] In another embodiment, if Figure 3 As shown, the number of the straight side drawing cores 10 is three, and the number of the turning drawing cores 9 is two.
[0033] The turning core 9 and the straight side core 10 can stably restrict and shape the anti-leakage decorative strip body 7, thereby improving the stability in use. At the same time, multiple points can be moved synchronously, and the anti-leakage decorative strip body 7 can be quickly demoulded.
[0034] In another embodiment, if Figure 3 As shown, the turning draw core 9 and the straight side draw core 10 are in contact with the anti-leakage decorative strip body 7 to form an undercut.
[0035] The turning core 9 and the straight side core 10 can stably perform molding processing on the undercut of the anti-leakage decorative strip body 7.
[0036] In another embodiment, if Figure 3 As shown, the turning draw core 9, the slider 8 and the fixed limiting guide block 11 are slidably fitted with each other.
[0037] It is convenient for the turning and drawing core 9 to be able to move stably, so that the end portion is separated from the inside of the anti-leakage decorative strip body 7, and then the anti-leakage decorative strip body 7 can be demoulded quickly.
[0038] The working principle of the utility model: during use, the glue can be injected from the top and the side under the action of the oblique push-in glue block 5, so that the anti-leakage decorative strip body 7 can enter the inner side of the fixed mold core 3 for molding. After the molding is completed, the steering draw core 9 and the straight side draw core 10 can be driven to move under the action of the slider 8, so that the ends of the steering draw core 9 and the straight side draw core 10 can be drawn out from the inner side of the anti-leakage decorative strip body 7, so as to quickly perform the demoulding process, stably perform the demoulding, and avoid the anti-leakage decorative strip body 7 from warping and deformation. The overall structure is simple and the operation is convenient and quick.
[0039] The above embodiments only express the specific implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
