The invention relates to the technical field of automobile tool machining and discloses an automobile part injection molding method and an injection mold. The automobile part injection molding methodcomprises the specific steps that an injection molding material is guided in, after the material is preliminarily formed, a forming cavity is pressurized, and after the material is completely solidified, heat in the forming cavity is brought away through a decompression exhaust method. Through the automobile part injection molding method, a plastic melt in the forming cavity can be cooled rapidly,and the mold forming efficiency is improved. 本发明涉及汽具加工技术领域，公开了种汽车零件注塑方法以及注塑模具，具体步骤包括导入注塑物料，物料初步成型后对成型腔加压，物料完全凝固后，通过降压排气的方法带有成型腔中的热量，本发明通过上述方法可快速度成型腔内的塑料熔体进行冷却，提高模具成型效率。
