[0002] The injection mold for the airbag shell of new energy vehicles is a tool specially used to produce airbag shells. It is usually made of high-strength steel and can withstand high temperature and high pressure environments. The surface treatment of the mold improves the wear resistance and molding quality, ensuring the safety and reliability of the final product. Through efficient injection molding technology, the mold can achieve mass production to meet the needs of the new energy vehicle industry.

[0003] A Chinese patent with patent announcement number CN215750471U discloses a guide device for an injection mold and an injection mold, including a support part and an insertion part, wherein the support part is connected to the insertion part, a matching curved surface is formed on the support part, and the support part can fit with the Green column of the laminated injection mold through the matching curved surface. There is a groove on the middle active part of the laminated injection mold, and the insertion part is inserted into the groove to limit the rotation of the guide device relative to the axis of the Green column. The patent plays an auxiliary guiding role, which is beneficial to the stable movement of the middle active part of the laminated injection mold.

[0004] However, the current injection mold has the following problems: the injection mold injects into the interior of the upper mold and the lower mold through the injection hole, and it is difficult to cool the injection mold. Therefore, the temperature inside the upper mold and the lower mold is high, which leads to the generation of bubbles in the material. The bubbles cannot be discharged during the molding process, and finally form bubble defects. Therefore, we propose an injection mold for a new energy vehicle airbag shell and an injection molding method thereof. Summary of the invention
