The present invention relates to a foaming mold of a sound absorbing material for a vehicle engine room, which foam molds a sound absorbing material for reducing noise of a vehicle engine room. The foaming mold of the present invention includes: a lower mold in which cavity is formed; an upper mold which is combined with the lower mold to open or close the cavity; and a gas exhaust means which is provided in a recessed portion of the upper mold to exhaust gas inside the cavity to the outside. The gas exhaust means includes: exhaust holes which are penetrated to connect the cavity with an external air; opening and closing members which integrally operate the exhaust holes to open or close the same; and cylinder units which vertically operate the opening and closing members. The opening and closing members maintain a predetermined distance from the exhaust holes, and two or more of the opening and closing members are formed in a second thickness portion thicker than a first thickness portion of the sound absorbing material for the vehicle engine room to be molded.
