The utility model discloses a low-pressure outer mold of an automobile
flywheel, and belongs to the field of manufacturing of automobile
flywheel parts. The automobile
flywheel low-pressure outer mold comprises a
workbench, the upper surface of the
workbench is fixedly connected with a main
body frame, an injection molding
pipe is installed above the main
body frame, the upper surface of the
workbench is fixedly connected with a guide rod set, and the outer wall of the guide rod set is slidably connected with an upper mold; a lower die is fixedly connected to the position, corresponding to the upper die, of the upper surface of the workbench,
metal particles and dust impurities in a die groove are absorbed, cleanliness of the surface of the die can be kept, the impurities are prevented from affecting the forming quality of a flywheel, surface defects can be reduced, the
surface smoothness and quality of the flywheel are improved, and meanwhile, the flywheel forming quality is improved. The
suction force at the
nozzle can absorb part of high temperature generated by the outer wall of the flywheel, so that the
cooling time after the flywheel is manufactured is shortened, and the production efficiency of the whole equipment for manufacturing the flywheel is improved.
