The present invention is installed on a press on which cavities are formed by upper and lower molds and is characterized by including jetting units which are installed on the sides of the upper or lower mold and which jet air to the cavities; lifting units which lift the jetting units; a sensing unit which senses the condition of the upper and lower molds which closing movement is completed; and a control unit which operates the jetting units when the sensing unit senses the condition of the upper and lower molds which closing movement is completed. The present invention removes scales remaining inside the cavities of the press by installing the jetting units lifted by the lifting units on the upper and lower molds of the press and jetting air to the cavities of the press with the jetting units, thereby obtaining molded articles having a good quality. |
