Technical Field

[0001] This utility model relates to the technical field of engine side covers, and in particular to a die-casting mold core structure for automobile engine side covers. Background Technology

[0002] During vehicle operation, the side cover of an automobile engine needs to have good heat dissipation performance. Therefore, the overall thickness of the side cover of an automobile engine is relatively small. When produced by die casting mold, the overall thickness of the mold cavity structure is relatively small, making it difficult for gas to escape quickly. This causes air shrinkage cavities to appear inside the side cover, which greatly reduces the quality of the product. In order to solve the above problems, the mold structure needs to be improved.
