PURPOSE: Provided is a mold for forming hydrofoam comprising a lubricating device, which can improve plasticity of the material and prevent the frictional face from being worn. CONSTITUTION: The mold comprises a top mold(10), a bottom mold(20), an inside forming face(40), and a plurality of grooves(50) formed at primary contact region of the forming face and raw material for placing lubricating agent to be projected in a spherical shape inside the grooves to reduce frictional resistance between the forming face and the material.
