PROBLEM TO BE SOLVED: To provide a metallic mold for casting aluminum composite parts and a casting method using the metallic mold with which a preform preset in the metallic mold is not broken or deformed caused by pressure when molten aluminum is impregnated, and the air in a gap of the preform is continuously and surely exhausted and the molten aluminum can uniformly be impregnated into the preform. SOLUTION: In the metallic mold for casting the aluminum composite parts, the upper surface of a cavity for pouring the molten aluminum is regulated with the bottom surface of the cavity and plurality of grooves for air-vent are formed on the preform-contacting surface abutting with the preform composed of the strengthening material included into the cavity in the bottom surface and also, a first metallic mold for forming push-out pin holes for inserting push-out pins communicated with these grooves, and a second metallic mold for regulating the cavity together with the bottom surface of the first metallic mold by mold-fastening to the bottom surface of the first metallic mold, and push-out pins inserted so as to be freely advanced/retreated under state of forming the clearance communicatable with the grooves for air-vent are provided.
