The present invention relates to an unmolding-oil spraying apparatus for a mold for spraying unmolding-oil to a mold (A) used to manufacture a concrete pole and a concrete pile. The unmolding-oil spraying apparatus comprises: a guide rail (10) installed on the upper side of the mold (A) in the direction of the mold (A); and unmolding-oil sprayers (40) which have driving units (20) and spray units (30) to move along the guide rail (10) and to spray the unmolding-oil toward the mold (A), and are installed on the guide rail (10). According to the present invention, two left and right unmolding-oil sprayers, which operate independently, spray the unmolding-oil toward the mold while freely moving along the guide rail in left and right directions. Therefore, the unmolding-oil spraying apparatus can increase work productivity by reducing time for spraying the unmolding-oil when compared to an existing apparatus. |
