[0002] New energy fast-charging seals are mainly used for fast-changing battery pack cooling pipes and circuit docking ports, and can also be used for ordinary battery packs that do not replace batteries. The function of this type of product is to reduce shock and buffer, and it can follow the movement well when the insertion is misaligned. At the same time, it also needs to have very good sealing performance to ensure that there is no leakage of liquid or electricity; it has excellent aging resistance and coolant resistance, and has the same life as the battery pack. With the rapid development of new energy vehicles, this type of product has a wide range of applications and a large demand for products.

[0003] When the existing fast-filling seal ring mold is used, the mold structure includes three templates, upper, middle and lower. The product is rubber molded, which will produce flash at the parting point, such as Figure 8 As shown in the figure, the flash is in the middle of the product. After the product is demoulded, it needs to be manually trimmed to remove the waste edge, resulting in low work efficiency and requiring a lot of manpower costs. In addition, due to the large number of deep grooves in the mold, the processing is difficult and the cost is high, and the product appearance is difficult to guarantee. For this reason, we propose a mold for processing new energy fast charging sealing rings. Summary of the invention

In the later stage, the accuracy of the insert and the deep groove 5 can be guaranteed by using medium wire cutting;

[0034] The through hole 202 is formed inside the middle mold 2 and passes through the upper and lower surfaces of the middle mold 2. The through hole 202 corresponds to the lower insert 4 and is connected to the inside of the deep groove 5 to form a processing cavity, so that the cavity is concentrated on one side of the lower mold 1, so that the product 7 can be processed through the cavity, and the flash after processing can be avoided from being concentrated in the middle of the product 7.

[0035] The upper mold 3 is disposed on the middle mold 2 to seal the through hole 202 .

[0036] Preferably, the middle part of the lower surface of the upper mold 3 protrudes downward to form a sealing block 301, and the inner side of the sealing block 301 is provided with an upper insert 302 for sealing the processing cavity, so as to facilitate sealing the cavity.

[0037] Preferably, a sealing groove 201 is provided on the middle mold 2, and the sealing groove 201 is equal to the sealing block 301 in shape and size, so as to better seal the multiple cavities and limit the free flow of liquid during processing.

[0038] Preferably, the sealing groove 201 is square, and the sealing groove 201 is communicated with the inside of the through hole 202 .

[0039] Preferably, the upper insert 302 and the lower insert 4 are staggered with each other, so as to improve the convenience of demoulding at a later stage through the staggered design.

[0040] Preferably, a plurality of lower inserts 4 are provided.

[0041] Preferably, the lower insert 4 includes a first insert 401, a second insert 402 and a third insert 403, the third insert 403 is fixed on the lower mold 1, the first insert 401 and the second insert 402 are staggered along the circumference of the third insert 403, and the first insert 401, the second insert 402 and the third insert 403 are not in contact with each other, which facilitates the processing of the lower insert 4 to form the deep groove 5.

[0042] Preferably, a plurality of first inserts 401 and a plurality of second inserts 402 are provided, so as to facilitate respective processing to form deep grooves 5 of predetermined shapes.

[0043] Preferably, a liquid injection hole 6 communicating with the interior of the deep groove 5 is provided on the front surface of the lower mold 1 to facilitate injection molding.

[0044] Existing Figure 8 As shown, both the upper and lower molds have cavities, which results in flash in the middle of the produced sealing ring, making it inconvenient to trim it later.

[0045] The working principle and use process of the present invention are as follows: during processing, the lower insert 4 is processed by using medium wire cutting to ensure the accurate size of the lower insert 4, thereby forming a deep groove 5, which can greatly reduce the difficulty of mold processing, shorten the mold processing cycle, save processing costs, and avoid the traditional deep groove processing, which uses customized lengthened tools or electric pulse processing. Customized tools often bounce and processing is unqualified; the electric pulse processing cycle is long and the efficiency is low, such as Fig. 9 As shown, after the mold of the present invention is processed, the cavities of the product are all concentrated on one side of the lower mold 1, which is convenient for avoiding that both the upper and lower molds have cavities. After the product is produced, the flash appears in the middle of the product, which is inconvenient for trimming. The mold of this patent concentrates the cavity on one side of the template, which is convenient for ensuring that frozen trimming can be used after the product is demolded. In addition, due to the complex structure of the product, it is difficult to demold the product, and it is easy to cause the product to tear during demolding. When designing the mold, this patent greatly improves the demolding efficiency and product qualification rate of the product through the staggered design of the upper insert 302 and the lower insert 4.
